MacedoniaKremydi - Sicilianou, Sophia2004Στο άρθρο αυτό παρουσιάζονται οι «θησαυροί» που έχουν βρεθεί στην περιοχή της Μακεδονίας κατά τους ρωμαϊκούς χρόνους με ιδιαίτερη έμφαση στα πρόσφατα ευρήματα. Συζητείται η διάδοση του ρωμαϊκού νομίσματος στην περιοχή και αντιδιαστέλλεται η σχετικά συχνή εμφάνιση των αργυρών υποδιαιρέσεων, κυρίως των δηναρίων, με την εξαιρετικά σπάνια εμφάνιση των χαλκών και την πλήρη απουσία των χρυσών. Οι «θησαυροί» που περιέχουν χάλκινες κοπές των επαρχιακών νομισματοκοπείων ταξινομούνται σε τέσσερεις γεωγραφικές ενότητες που αντιστοιχούν στις τέσσερεις μερίδες. Τα συμπεράσματα που προκύπτουν από το υλικό είναι τα ακόλουθα: Η συντριπτική πλειονότητα των χάλκινων κοπών που κυκλοφορούσαν στη περιοχή ανήκαν στα μακεδονικά νομισματοκοπεία ενώ, εντελώς εξαιρετικά, εμφανίζονται νομίσματα από τη Μικρά Ασία. Επιπλέον, παρόλο που οι «θησαυροί» του πρώτου αιώνα είναι ελάχιστοι, φαίνεται πως την περίοδο αυτή τα νομίσματα δεν απομακρύνονταν σχεδόν καθόλου από την περιοχή που κόπηκαν. Κατά τον δεύτερο αλλά κυρίως κατά τον τρίτο αιώνα, οι επαρχιακές κοπές κυκλοφορούσαν ευρύτερα μέσα στη Μακεδονία• οι κοπές της πρώτης μερίδας ωστόσο εξακολουθούσαν να μετακινούνται λιγότερο, τουλάχιστον προς δυσμάς. Η ευρύτερη κυκλοφορία των νομισμάτων του τρίτου αιώνα θα πρέπει να συνδέεται με την παρατηρημένη μετρολογική αλλά και τεχνοτροπική τους ομοιομορφία. Τέλος προτείνεται πως, αντίθετα με ότι συνέβαινε σε παλαιότερες περιόδους, οι κοπές των επαρχιακών πόλεων στους αυτοκρατορικούς χρόνους μπορούσαν να γίνουν αμοιβαία αποδεκτές ως νόμιμο μέσο συναλλαγής από γειτονικές πόλεις. Εάν η υπόθεση είναι ορθή, τότε η πρακτική αυτή αποτελεί ένα πρώτο βήμα προς την κατεύθυνση της νομισματικής ενοποίησης της αυτοκρατορίας που επεβλήθη με τις μεταρρυθμίσεις του Διοκλητιανού.Patterns of monetary circulation in Roman Macedonia: The hoard evidenceΝομισματική κυκλοφορία στη Ρωμαϊκή Μακεδονία: Η μαρτυρία των θησαυρώνLCC::C::CJLCC::D::D1::D51Textenghttp://hdl.handle.net/10442/8425 +

ΜακεδονίαΡιζάκης, ΑθανάσιοςΤουρατσόγλου, Γ.1987La Haute Macédoine, une région délimitée par deux dépressions parallèles et enfermée de tous les côtés par les masses montagneuses de Pinde, Cambuniens, Olympe, Vermion et Caticica loin de la mer et des grands centres urbains des régions voisines de la Grèce du Sud et de la Basse Macédoine, elle resta toujours en marge de l'intérêt des historiens des temps anciens. D'autre part la pauvreté des vestiges archéologiques n'encouragea pas les spécialistes modernes à entreprendre son exploration et son étude systématique. Il est naturel que toute apparition d'étude, basée sur le matériel archéologique de la Haute Macédoine soit, donc, considérée comme une contribution bienvenue pour la connaissance de cette contrée isolée qui fut "le berceau des Macédoniens". Or les trois articles de D. Samsaris, parus dans Makedonika 22, 1982 (1984) 259-291; 295-306; 485-491 et traitant de l'anthroponymie, des institutions et comprenant des remarques sur la langue des inscriptions est un événement qui mérite l'attention des savants. La présente critique reflète l'intérêt qu'ont suscité ces études et sa seule ambition est d'aider à la meilleure compréhension de certains points épineux tout en apportant d'autres solutions. Sans pénétrer dans les détails, qui sont exposés dans notre article, il faut mettre l'accent sur une constatation générale: il est universellement adopté que les travaux de synthèse ne doivent pas précéder ceux de base, sinon l'auteur de tels projets doit mobiliser une très grande attention ainsi qu*un sens critique pour éviter les malentendus et les conclusions simplifiées. Toute entreprise, contraire à ces principes, contient un très grand danger que l'auteur η 'a pas pu éviter: les erreurs de lecture, la confusion dans les provenances et les interpretations parfois superficielles, l'ont conduit à des statistiques et à des conclusions qui sont à refaire. En effet la recherche historique ne peut s'effectuer qu ' après une étude simultanée et approfondie des documents littéraires, archéologiques et épigraphiques et les synthèses prématurées entraînent des risques de désorientation pour l'auteur lui-même et ses lecteurs.Τρεις μελέτες για την Άνω Μακεδονία.

DelosMacedoniaElisEuboea4th - 1st centuries b.C.Andrianou, Dimitra2007Miniature furniture falls within the study of full-sized furniture and replicas on a much reduced scale. Greek Hellenistic miniature furniture, in particular, forms a small group of objects made mainly of lead and found in domestic, funerary and sacred areas. The precise context is often unknown. Various hypotheses, often influenced by modern habits of furniture use, have been put forward concerning their meaning and production. This study focuses on miniature chairs and tables excavated in Delos, Macedonia, Elis and Euboea and dated to between the 4th and 1st centuries BC. Evidence of miniature furniture in literary and epigraphical texts will be considered. Since there is no unique way of interpreting these artefacts, this study will evaluate their significance on the basis of the evidence available, while also attempting to shed light on aspects of daily- and afterlife.A World in Miniature: Greek Hellenistic Miniature Furniture in ContextLCC::C::CCTextenghttp://hdl.handle.net/10442/8509 +

Λόγω της θέσης της, στη δυτική ακτή του νησιού, όπου βρίσκεται και η ευφορότερη κοιλάδα όλης της Κέας, η οικονομία της πόλης ήταν προσανατολισμένη τόσο στις θαλάσσιες εμπορικές ανταλλαγές, όσο και στην εκμετάλλευση των γαιών της περιοχής.

The + benefits of MTFC for efficient freeway traffic flow have been demonstrated recently using an + optimal control approach and a feedback control approach. In this paper, both control approaches + are reviewed and applied to a freeway network in a simulation environment. The validated network + model used reflects an actual freeway (a ring-road), fed with actual (measured) demands. The + optimal and feedback control results are discussed, compared and demonstrated to improve + significantly the system performance. In particular, the feedback control scheme is deemed + suitable for immediate practical application as it takes into account operational requirements + and constraints, while its results are shown to be satisfactory. In addition, the control system + performance was not very sensitive to variations of the parameters of the feedback controller. + This result indicates that the burden associated with fine tuning of the controller may be + reduced in the field. + + ANPET - Associação Nacional de Pesquisa e Ensino em Transportes + + Presented on: Transportes + peer-reviewed + Bibliographic citation: R.C.

The benefits of MTFC for efficient freeway traffic flow have been demonstrated recently using an optimal control approach and a feedback control approach. In this paper, both control approaches are reviewed and applied to a freeway network in a simulation environment. The validated network model used reflects an actual freeway (a ring-road), fed with actual (measured) demands. The optimal and feedback control results are discussed, compared and demonstrated to improve significantly the system performance. In particular, the feedback control scheme is deemed suitable for immediate practical application as it takes into account operational requirements and constraints, while its results are shown to be satisfactory. In addition, the control system performance was not very sensitive to variations of the parameters of the feedback controller. This result indicates that the burden associated with fine tuning of the controller may be reduced in the field.ANPET - Associação Nacional de Pesquisa e Ensino em TransportesPresented on: Transportespeer-reviewedBibliographic citation: R.C.

An optimisation problem, formulated as a Quadratic Programming (QP) problem, is developed with the purpose of minimising traffic congestion. The proposed problem is based on a first-order macroscopic traffic flow model able to capture the lane changing and the capacity drop phenomena. An application example demonstrates the achievable improvements in terms of the Total Time Spent if the vehicles travelling on the motorway are influenced by the control actions computed as a solution of the optimisation problem.Παρουσιάστηκε στο: International Conference on Engineering and Applied Sciences OptimizationNational Technical University of AthensΒιβλιογραφική αναφορά: C.

Although it was designed mainly to enhance driver comfort and passengers’ safety, it also affects the dynamics of traffic flow. For this reason, a strong research interest in the field of modelling and simulation of ACC-equipped vehicles has been increasingly observed in the last years. In this work, previous modelling efforts reported in the literature are reviewed, and some critical aspects to be considered when designing or simulating such systems are discussed. Moreover, the integration of ACC-equipped vehicle simulation in the commercial traffic simulator Aimsun is described; this is subsequently used to run simulations for different penetration rates of ACC-equipped vehicles, different desired time-gap settings and different networks, to assess their impact on traffic flow characteristics.Παρουσιάστηκε στο: International Symposium of Transport Simulation 2014ElsevierBibliographic citation: I.A.

Previous studies in a macroscopic simulator have shown optimal and feedback MTFC potential to improve traffic conditions. In this paper, local feedback MTFC is applied in microscopic simulation for an on-ramp merge bottleneck. Traffic behavior reveals important aspects that had not been previously captured in macroscopic simulation. Mainly, the more realistic VSL application at specific points instead of along an entire freeway section produces a slower traffic response to speed limit changes. In addition, the nonlinear capacity flow/speed limit relation observed in the microscopic model is more pronounced than what was observed at the macroscopic level. After appropriate modifications in the control law, significant improvements in traffic conditions are obtained.Institute of Electrical and Electronics EngineersPresented on: IEEE Transactions on Intelligent Transportation Systemspeer-reviewedBibliographic citation: E.R.

This may lead to improvements in traffic management because of the augmented possibilities of using VACS both as sensors and as actuators. To achieve this, appropriate studies, developing potential control strategies to exploit the VACS availability, are essential. This paper describes a model predictive control framework that can be used for the integrated and coordinated control of a motorway system, considering that vehicles are equipped with specific VACS. Microscopic simulation testing demonstrates the effectiveness and the computational feasibility of the proposed approach.Παρουσιάστηκε στο: 17th International IEEE Conference on Intelligent Transportation SystemsInstitute of Electrical and Electronics EngineersBibliographic citation: C.

Based on appropriate VACS-based actuators, future traffic control may incorporate vehicle speed control and lane-assignment or lane-changing recommendations. To this end, an appropriate traffic flow model is needed, both for control strategy design and as a no-control base case for comparative evaluation studies. In this context, this paper presents a novel first-order multi-lane macroscopic traffic flow model for motorways which is mainly intended for use within a related optimal control problem formulation. The starting point is close to the well-known cell-transmission model (CTM), which is modified and extended to consider additional aspects of the traffic dynamics, such as lane changing and the capacity drop. The model has been derived with a view to combine realistic traffic flow description with a simple (piecewise linear) mathematical form, which can be exploited for efficient optimal control problem formulations. Although the model has been primarily derived for use in future traffic conditions including VACS, it may also be used for conventional traffic flow representation. In fact, the accuracy of the proposed modelling approach is demonstrated through calibration and validation procedures using conventional real data from an urban motorway located in Melbourne, Australia.Presented on: Transportation Research BoardBibliographic citation: C.

Under critical traffic conditions, the merging of main road traffic and on-ramp traffic is known to trigger speed breakdown and congestion. Additionally, merging is one of the most stressful tasks for the driver, since it requires a synchronized set of observations and actions. Consequently, drivers often perform merging maneuvers with low efficiency. Emerging vehicle technologies, such as cooperative adaptive cruise control and/or merging-assistance systems, are expected to enable the so-called “cooperative merging”. The purpose of this work is to propose a cooperative merging system and evaluate its performance and its impact on highway capacity. The modeling and simulation of the proposed methodology is performed within the framework of a microscopic traffic simulator. The proposed model allows for the vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication, which enables the effective handling of the available gaps between vehicles. Different cases are examined through simulations, in order to assess the impact of the system on traffic flow, under various traffic conditions. Useful conclusions are derived from the simulation results, which can form the basis for more complex merging algorithms and/or strategies that adapt to traffic conditions.Presented on: American Society of Mechanical EngineersBibliographic citation: I.

ALINEA uses real-time occupancy measurements from the ramp flow merging area that may be at most few hundred meters downstream of the metered on-ramp nose. In many practical cases, however, bottlenecks with smaller capacity than the merging area may exist further downstream for various reasons, which suggests using measurements from those further downstream bottlenecks. Recent theoretical and simulation studies indicate that ALINEA may lead to a poorly damped closed-loop behavior in this case, but PI-ALINEA, a suitable Proportional-Integral (PI) extension of ALINEA, can lead to satisfactory control performance. This paper addresses the same local ramp-metering problem in the presence of downstream bottlenecks, with a particular focus on the general capacity of PI-ALINEA with three distinct types of bottleneck that may often be encountered in practice, i.e. (1) an uphill case; (2) a lane-drop case; (3) an un-controlled on-ramp case. Extensive simulation studies are conducted using a macroscopic traffic flow model to demonstrate that the performance of ALINEA indeed deteriorates in each of these bottleneck cases, +while significant improvement is obtained using PI-ALINEA in all cases. Moreover, with its control parameters appropriately tuned beforehand, PI-ALINEA is found to be universally applicable, with little fine-tuning required for field applications.Παρουσιάστηκε στο: 17th International IEEE Conference on Intelligent Transportation SystemsInstitute of Electrical and Electronics EngineersBibliographic citation: Y.

We adopt the probabilistic model of Vlassis and Toussaint (2009) for model-free RL, and we propose a Monte Carlo EM algorithm (MCEM) for control learning that searches directly in the space of controller parameters using information obtained from randomly generated robot trajectories. MCEM is related to, and generalizes, the PoWER algorithm of Kober and Peters (2009). In the finite-horizon case MCEM reduces precisely to PoWER, but MCEM can also handle the discounted infinite-horizon case. An interesting result is that the infinite-horizon case can be viewed as a ‘randomized’ version of the finite-horizon case, in the sense that the length of each sampled trajectory is a random draw from an appropriately constructed geometric distribution. We provide some preliminary experiments demonstrating the effects of fixed (PoWER) vs randomized (MCEM) horizon length in two simulated and one real robot control tasks. +Springer VerlagPresented on: Autonomous Robotspeer-reviewedBibliographic citation: N.

The RothC model was used in a Monte-Carlo based framework to assess the uniqueness of solution in carbon sequestration simulations. The model was applied to crop production to set aside conversions in Iowa (sandy clay-loam soil, humid-continental climate) and Greece (clay-loam soil, +Mediterranean). The model was initialized and calibrated with particulate organic carbon data obtained by physical fractionation. The calibrated values for the Iowa grassland were 5.05 t C ha-1, 0.34 y-1, and 0.27 y-1 24 for plant litter input and decomposition rate constants for resistant plant material (RPM) and humus, respectively, while for the Greek shrubland these were 3.79 +t C ha-1, 0.21 y-1, and 0.0041 y-126 , correspondingly. The sensitivity analysis revealed that for both sites, the total plant litter input and the RPM rate constant showed the highest sensitivity. The Iowa soil was projected to sequester 17.5 t C ha-1 and the Greek soil 54 tC ha- 28 1 29 over 100 years and the projected uncertainty was 65.6% and 70.8%, respectively.

After a release of nitrates (NO3--N) in the first 6 days after compost incorporation, soil NO3--N content remained constant in all the treatments by day 62 suggesting immobilization of N. Then, soil NO3--N content increased, especially in the highest compost dose implying that the immobilization effect has been relieved, at least to some extent. amoA gene copies of ammonia oxidizing archaea (AOA) and ammonia oxidizing bacteria (AOB) followed strictly the pattern of soil NO3--N content throughout the study providing evidence that both groups were involved in ammonia oxidation and changes in their population can be used as ‘indicator’ for predicting changes in soil nitrification status. Moreover, the strong correlation between AOA 12 and AOB amoA copies (R2: 0.94) and the high slope (13) of the curve suggest that AOA had probably a more important role on ammonia oxidation under conditions of low ammonia availability. Denitrifying genes (nirS, nirK, nosZ) also followed the general pattern of soil NO3–-N and they were strongly correlated with both groups of ammonia oxidizers, and particularly archaea, suggesting strong interrelationships among them. Losses of N through denitrification, as they were estimated from total nitrogen decrease, were inversely related to soil NO3--N content. Similar to ammonia oxidizers, denitrifying gene copies did not differ among compost treatments an effect that could be probably explained by the low availability of organic-C of the MSW compost and hence the competition with aerobic heterotrophs.Springer VerlagPresented on: peer-reviewedBibliographic citation: N.

Sustainable agricultural practices are necessary if we are to face the challenge of food security while preserving the integrity of soil and aquatic ecosystems. Conservation agriculture which is comprised of zero or minimum tillage, carbon amendments and crop rotations holds great promise in delivering higher yields, using water and soil resources in a sustainable manner and increasing soil biodiversity. This paper presents a synthesis of current knowledge on soil ecosystem processes and modeling with a focus on carbon and nitrogen dynamics and their link to soil structure, and proposes a conceptual framework for model parameterization capable of predicting critical soil functions and potential shifts. +We reviewed the dynamics of carbon, nitrogen and soil structure with an emphasis in elucidating predominant state variables and the interaction with plants and food web dynamics. Existing models that simulate the dynamics of organic matter and structure in soils at various scales were evaluated for their ability to simulate the functions of soil ecosystem. Current modeling approaches treat carbon, nitrogen and soil structure for the most part separately without incorporating feedback mechanisms. The synergistic and antagonistic processes between bacteria and plants and fungi and plants are partially understood and more importantly the community lacks the knowledge to predict if and when these processes fail and any related potential ecosystem shift. A conceptual modeling framework is proposed, developed along the following three axes: incorporate emerging ecosystem state variables, account for the ecology of life in soils, and model processes from first principles. A synthesis of the carbon and nitrogen cycles is suggested in which the dynamics of the two cycles are interlinked. State variables in soil ecosystem models that link carbon and nitrogen dynamics with soil structure and the biological community are recommended. Plant feedback mechanisms with the physical, biochemical and biotic soil components and the symbiotic relationship between bacteria, fungi, and plants should be modeled using principles from the ecological succession theory that would relate the taxonomic structure with function and nutrient fluxes. A conceptual model of soil structure and soil stability is suggested that links the soil organic matter sub-model to an aggregation sub-model and a dynamic soil structure sub-model. The development of new generation soil ecosystem models is a necessary step to better quantify soil functions, assess possible soil tipping points, and develop methods to restore soil functions.Appearing in: Sustainable Agriculture ReviewsSpringer VerlagBibliographic citation: N.

The aquifer is packed with a wellcharacterized +relatively uniform sand. A conservative tracer is employed for the +determination of the longitudinal and transverse aquifer dispersivities. The dissolution +studies are conducted using a circular trichloroethylene (TCE) pool. The sorption +characteristics of TCE onto the aquifer sand are independently determined from a flowthrough +column experiment. Steady state dissolved TCE concentrations at specific +downstream locations within the aquifer are collected under three different interstitial +velocities.

The dispersed source is viewed as an active device contributing towards the regulation of real and reactive power flows while improving the stability of the power system. Conceptual means are developed for an effective DSG-utility grid interface. Computer models of appropriate interconnection and control equipment are used in simulation studies to test the effectiveness of control strategies and optimize design parameters. Simulation results indicate that load frequency control and voltage regulation may be effectively accomplished with dispersed generators within a fraction of the time required for conventional regulating units. Appropriate modulation and conditioning of the DSG-output power can assist in damping out undesirable power oscillations. Implementation of the proposed policies may result in reduced load following requirements for conventional power generating units, increase the value and acceptability of new energy technologies, and improve power quality and stability of the interconnected system.Institute of Electrical and Electronics EngineersΠαρουσιάστηκε στο: Power Systems, IEEE Transactions onpeer-reviewedBibliographic citation: G.J.

One of the emerging techniques in this area is liquid-phase microextraction (LPME), where a hollow fibre impregnated with an organic solvent is used to accommodate or protect microvolumes of acceptor solution. This novel methodology proved to be an extremely simple, low-cost and virtually solvent-free sample-preparation technique, which provided a high degree of selectivity and enrichment by additionally eliminating the possibility of carry-over between runs. This article presents the different modes and hollow-fibre configurations of LPME, followed by an up-to-date summary of its applications. The most important parameters and practical considerations for method optimisation are also discussed. The article concludes with a comparison of this novel method with solid-phase microextraction (SPME) and single-drop microextraction (SDME). +ElsevierPresented on: peer-reviewedBibliographic citation: E.

The most recent trends include solvent microextraction, a miniaturisation of the traditional liquid–liquid extraction method, where the solvent to aqueous ratio is greatly reduced. Single-drop microextraction is a methodology that evolved from this approach. It is a simple, inexpensive, fast, effective and virtually solvent-free sample pretreatment technique. This article provides a detailed and updated discussion of the developments, modes and applications of single-drop microextraction, followed by a brief description of the theoretical background of the method. Finally, the most important parameters as well as some practical considerations for method optimisation and development are summarised.ElsevierPresented on: Trends in Analytical Chemistrypeer-reviewedBibliographic citation: E Psillakis, N.

Anion selective membranes containing a few micrograms of different complexing reagents in polyvinyl chloride (PVC) matrix were produced in quartz reflectors. The membranes were immersed in water solutions with low concentrations of cationic metals, Cu, Co, Ni, Zn, and of anionic ligands (CN−, etc.). After the equilibration time the reflectors were left to dry and they were analyzed by Total X-Ray Fluorescence (TXRF). Many experimental parameters (pH effect, size of the membrane, volume sample) were examined. The minimum detection limits were estimated to be 1 ng/ml for all metallic cations even in seawater. The method needs less working labor than other enrichment procedures, the cations are collected directly on the TXRF reflector surface and very small chemical reagent consumption is needed.

The quality of the interconnected system performance is specified in terms of operational constraints. Load-flow and power-system-stability studies were preformed in order to evaluate the penetration impact of a 4·5 MW wind farm on the local grid fo Sitia-Crete. The results show that the above wind energy penetration level will not cause any problem to the existing electric power grid.Taylor & FrancisPresented on: International Journal of Solar Energypeer-reviewedBibliographic citation: K.C.

Parameters, such as organic solvent, exposure time, agitation, organic drop volume and salt concentration were controlled and optimised. Overall, extraction was achieved by suspending a 1.5 μl toluene drop to the tip of a microsyringe immersed in a 5 ml donor aqueous solution containing 2.5% NaCl (w/v) and stirred at 800 rpm. The developed protocol was found to yield a linear calibration curve in the concentration range from 0.5 to 100 μg l−1 for all target analytes. Under selected ion monitoring mode, the limits of detection were found to be in the range between 0.010 and 0.073 μg l−1.Παρουσιάστηκε στο: Analytica chimica actapeer-reviewedBibliographic citation: D.

This compound has two potentially chelating N,N′-bidentate arms linked by an apical PO 2 - group. Reaction with AgNO 3 , Tl(O 2 CMe), Pb(NO 3 ) 2 or Ba(NO 3 ) 2 in dry MeCN followed by recrystallisation afforded crystals of the complexes [AgL]·2H 2 O, [TlL]·MeOH, [PbL 2 ]·H 2 O and [(BaL 2 ) 3 ]·6MeCN·2H 2 O respectively, all of which have been crystallographically characterised. The compound [AgL]·2H 2 O contains infinite helical chains (AgL) ∞ in which each ligand donates one N,N′-bidentate arm to each of two metals and each metal ion is four-co-ordinated by two arms from different ligands. The strands are held together in the crystal by a complex network of hydrogen bonds involving lattice water molecules and also by aromatic π-stacking interactions. The compound [TlL]·MeOH is likewise a one-dimensional helical polymer of TlL units, with each ligand bridging two metals and each Tl ion in a ‘2 + 3’ co-ordination geometry with two short bonds to ligands (<2.71 Å) and three longer, weak bonds (>2.87 Å): there is an obvious gap in the co-ordination sphere due to a stereochemically active lone pair. A combination of interstrand aromatic π-stacking interactions and hydrogen-bonding interactions involving the lattice MeOH molecule is present.Royal Society of ChemistryΠαρουσιάστηκε στο: Journal of the Chemical Society, Dalton Transactionspeer-reviewedBibliographic citation: E.

Dihydrobis[3-(2-pyridyl)pyrazolyl]borate (L 1 ) - is a tetradentate ligand with two bidentate chelating pyridyl/pyrazolyl arms linked by an apical BH 2 group; 2,6-bis(1H-pyrazol-3-yl)pyridine (L 2 ) is a terdentate chelating ligand reminiscent of terpyridine. Reaction of L 1 with lanthanide salts gave complexes of the type [M(L 1 ) 2 X] n+ ; the crystal structures of [Eu(L 1 ) 2 (dmf)][ClO 4 ]· 2.5CH 2 Cl 2 , [Tb(L 1 ) 2 (NO 3 )]·2CH 2 Cl 2 and [Tb(L 1 ) 2 (H 2 O)][L 1 ]· H 2 O·0.5CH 2 Cl 2 were determined and all contain two tetradentate ligands L 1 and an ancillary ligand X [dimethylformamide (dmf), nitrate or water] whose nature depends on the reaction/recrystallisation conditions to complete the co-ordination sphere. Luminescence studies of [Tb(L 1 ) 2 (NO 3 )] in water or D 2 O and MeOH or CD 3 OD showed that in methanol the solvation number q is ≈1.8, consistent with displacement of nitrate by the solvent; however in water q ≈ 4.5, indicating additional displacement of some of the N-donor heterocyclic rings of L 1 by co-ordinating water molecules. Reaction of L 2 with lanthanide salts afforded [M(L 2 ) 3 ] 3+ , all isolated as their hexafluorophosphate salts. The crystal structures of three of these (M = Eu, Gd or Ho) showed that they are isostructural and isomorphous, with tricapped trigonal-prismatic nine-co-ordinate geometries similar to that of [M(terpy) 3 ] 3+ (terpy = 2,2′:6′,2″- terpyridine).

Treatment of 4c with the Ru(CO) 2 (η 5 -7,8-C 2 B 9 H 11 ) fragment yielded the diruthenium complex [Ru 2 (μ-Ph 2 PCH 2 PPh 2 )(CO) 4 (η 5 -7,8-C 2 B 9 H 11 ) 2 ] (6). The structure, based on the linking of two Ru(CO) 2 (η 5 -7,8-C 2 B 9 H 11 ) groups by the ligand Ph 2 PCH 2 PPh 2 , was determined by X-ray crystallography.

Photolysis took place directly on the polydimethylsiloxane coating of the LT-SPME fibre, yielding an “in situ” generation of photoproducts. Maintaining the temperature of the cold fibre at 0 °C eliminated, for the first time, problems of analyte losses due to volatilisation, inherent to the conventional room temperature photo-SPME studies. During the present studies, nearly complete photoremoval of HCB could be achieved within 20 min of irradiation. Photoreduction through photodechlorination was shown to be the main decay pathway in which lesser chlorinated congeners were sequentially formed as intermediates. Accordingly, initial generation of pentachlorobenzene was followed in order from 1,2,3,5-tetrachlorobenzene, 1,2,4,5-tetrachlorobenzene and 1,3,5-trichlorobenzene.

Initial experiments revealed that the direct photolysis of 2,4-DNT in deionized water solutions under sunlight and artificial light followed a pseudo-first order kinetic. Humic acids (HA) appeared to act as sensitizers in the aqueous photolysis of 2,4-DNT and the calculated half life was found to be approximately 2 h, which is faster than the half life calculated in the case of deionized water (∼4 h). The presence of salt (NaCl) in the deionized water solutions was found to have a more pronounced sensitizing effect upon the photolysis of 2,4-DNT, yielding half lives of the order of 1 h. Investigations on seawater and groundwater spiked with 2,4-DNT, revealed that photolysis is enhanced in the order seawater > groundwater∼deionized water.Παρουσιάστηκε στο: Journal of hazardous materialspeer-reviewedBibliographic citation: O.

In HL, an intramolecular OH … N hydrogen bond between the phenolic OH and the adjacent nitrogen atom of the phenanthroline fragment constrains these two donor atoms to be cisoid, with the proton ‘chelated’. The molecules of HL are associated into pairs in the crystal via a face-to-face aromatic π-stacking interaction. Complex 1 has a conventional distorted octahedral structure; sections of the aromatic ligands overlap between adjacent molecules to form an interleaved stack. It is high-spin down to 83 K, and its EPR spectrum (frozen glass at 77 K) is entirely typical of a rhombically distorted high-spin FeIII site.PergamonΠαρουσιάστηκε στο: Polyhedronpeer-reviewedBibliographic citation: J.

A total of 9 sampling sites were chosen (4 in urban and 5 in non-urban areas) in each country and pine needles from the Pinus pinea L. species were collected. Although the mean total PAH levels was similar in the three countries (279 ± 236 ng g−1 for Portugal, 294 ± 258 ng g−1 for Spain, 301 ± 253 ng g−1 for Greece, all dry weight) and, in general, 3-ring and 4-ring PAHs were predominant (being phenanthrene consistently the most abundant), there were some visible differences in the aromatic ring patterns and possible sources between the three regions. Source apportionment was done using PAH ratios (Phen/Ant and Flt/Pyr crossplots) and reflected mixed petrogenic and pyrogenic sources. Furthermore, Principal Component Analysis (PCA) clearly separated the urban and the non-urban sites and all three countries, which reinforces that the sources of contaminations vary in each case and the suitability of pine needles for trans-boundary biomonitoring of PAHs.Taylor & Francis GroupΠαρουσιάστηκε στο: Analytical Letterspeer-reviewedBibliographic citation: N.

The procedure was investigated both theoretically and experimentally. According to the theory, reducing the total pressure increases the vapor flux of chemicals at the soil surface, and hence improves HSSPME extraction kinetics. Vac-HSSPME sampling could be further enhanced by adding water as a modifier and creating a slurry mixture. For these soil-water mixtures, reduced pressure conditions may increase the volatilization rates of compounds with a low KH present in the aqueous phase of the slurry mixture and result in a faster HSSPME extraction process. Nevertheless, analyte desorption from soil to water may become a rate-limiting step when significant depletion of the aqueous analyte concentration takes place during Vac-HSSPME. Sand samples spiked with PAHs were used as simple solid matrices and the effect of different experimental parameters was investigated (extraction temperature, modifiers and extraction time). Vac-HSSPME sampling of dry spiked sand samples provided the first experimental evidence of the positive combined effect of reduced pressure and temperature on HSSPME. Although adding 2 mL of water as a modifier improved Vac-HSSPME, humidity decreased the amount of naphthalene extracted at equilibrium as well as impaired extraction of all analytes at elevated sampling temperatures. Within short HSSPME sampling times and under mild sampling temperatures, Vac-HSSPME yielded linear calibration curves in the range of 1–400 ng g−1 and, with the exception of fluorene, regression coefficients were found higher than 0.99. The limits of detection for spiked sand samples ranged from 0.003 to 0.233 ng g−1 and repeatability from 4.3 to 10 %. Finally, the amount of PAHs extracted from spiked soil samples was smaller compared to spiked sand samples, confirming that soil could bind target analytes more strongly and thus decrease the readily available fraction of target analytes.ElsevierPresented on: Analytica Chimica Actapeer-reviewedBibliographic citation: E.

This approach uses diagrams instead of abstract symbols to visualize complex multifold integrals that appear in the perturbative expansion of the stochastic flow solution and reduces the original flow problem to a closed set of equations for the mean and the covariance functions. Diagrammatic analysis provides an improved formulation of the flow problem over conventional first-order series approximations, which are based on assumptions such as constant mean hydraulic gradient, infinite flow domain, and neglect of cross correlation terms. This formulation includes simple schemes, like finite-order diagrammatic perturbations that account for mean gradient trends and boundary condition effects, as well as more advanced schemes, like diagrammatic porous media description operators which contain infinite-order correlations. In other words, diagrammatic analysis covers not only the cases where low-order diagrams lead to good approximations of flow, but also those situations where low-order perturbation is insufficient and a more sophisticated analysis is needed. Diagrams lead to a nonlocal equation for the mean hydraulic gradient in terms of which necessary conditions are formulated for the existence of an effective hydraulic conductivity. Three-dimensional flow in an isotropic bounded domain with Dirichlet boundary conditions is considered, and an integral equation for the mean hydraulic head is derived by means of diagrams. This formulation provides an explicit expression for the boundary effects within the three-dimensional flow domain. In addition to these theoretical results, the numerical performance of the diagrammatic approach is tested, and useful insight is obtained by means of one-dimensional flow examples where the exact stochastic solutions are available.Παρουσιάστηκε στο: Water Resources Researchpeer-reviewedBibliographic citation: G.

An issue of practical interest is the permissible range and the relations between different fractal exponents used to characterize these processes. Here we derive the bounds of the covariance exponent for fGn and the Hurst exponent for fBm based on the permissibility theorem by Bochner. We exploit the theoretical constraints on the spectral density to construct explicit two-point (covariance and structure) functions that are band-limited fractals with smooth cutoffs. Such functions are useful for modeling a gradual cutoff of power-law correlations. We also point out certain peculiarities of the relations between fractal exponents imposed by the mathematical bounds. Reliable estimation of the correlation and Hurst exponents typically requires measurements over a large range of scales (more than 3 orders of magnitude). For isotropic fractals and partially isotropic self-affine processes the dimensionality curse is partially lifted by estimating the exponent from measurements along fixed directions. We derive relations between the fractal exponents and the one-dimensional spectral density exponents, and we illustrate the relations using measurements of paper roughness.Springer-VerlagΠαρουσιάστηκε στο: Stochastic Environmental Research and Risk Assessmentpeer-reviewedBibliographic citation: D.T.

Fuzzy PID, fuzzy PD and adaptive fuzzy PD control methods are applied. The inputs to any controller are: the PMV index affecting thermal comfort, the CO2 concentration affecting indoor air quality and the illuminance level affecting visual comfort. The adaptive fuzzy PD controller adapts the inputs and outputs scaling factors and is based on a second order reference model. More specifically, the scaling factors are modified according to a sigmoid type function, in such a way that the measured variable to be as closer as possible to the reference model. The adaptive fuzzy PD controller is compared to a non-adaptive fuzzy PD and to an ON–OFF one. The comparison criteria are the energy required and the controlled variables response. Both, energy consumption and variables responses are improved if the adaptive fuzzy PD type controller is used. The buildings’ response to the control signals has been simulated using MATLAB/SIMULINK.ElsevierPresented on: Energy and Buildingspeer-reviewedBibliographic citation: D. Kolokotsa, D.

Several approaches including Gaussian encoding backpropagation (BP), window random activation, radial basis function networks, real-time recurrent neural networks and their innovative variations are proposed, compared and discussed in this paper. The performance of each presented structure is evaluated by means of an extensive simulation study, using actual hourly load data from the power system of the island of Crete, in Greece. The forecasting error statistical results, corresponding to the minimum and maximum load time-series, indicate that the load forecasting models proposed here provide significantly more accurate forecasts, compared to conventional autoregressive and BP forecasting models. Finally, a parallel processing approach for 24 h ahead forecasting is proposed and applied. According to this procedure, the requested load for each specific hour is forecasted, not only using the load time-series for this specific hour from the previous days, but also using the forecasted load data of the closer previous time steps for the same day. Thus, acceptable accuracy load predictions are obtained without the need of weather data that increase the system complexity, storage requirement and cost.ElsevierPresented on: Electric Power Systems Researchpeer-reviewedBibliographic citation: K.

Their installation in existing buildings is far from being cost effective due to the incompatibility of communication protocols between BEMS designed by various manufacturers and unavoidable modifications for data transmission. On the other hand, current research for energy efficient buildings has proved that although the design and the facilities including BEMS aim to satisfy the thermal and visual comfort plus the air quality demands while minimising the energy needs, they often do not reach their goals due to users interference. Latest trends in designing Intelligent Building Energy Management Systems (IBEMS) offer a Man Machine Interface that could store the users preferences and adapt the control strategy accordingly. The objectives of the present paper are to present the advantages of the use of a man machine interface based on a smart card terminal together with fuzzy control techniques in satisfying the users preferences plus to underline the capabilities that the LON network offers to the design. A fuzzy PID controller is developed to reach the first of the above objectives. The monitoring of the energy consumption along with satisfying the users preferences is achieved by the use of a suitable cost function for the whole system. All the above parameters as well as the cost function are kept between acceptable limits. The overall control system including the cost function is modeled and tested using MATLAB/SIMULINK. The implementation of the control system in an existing building requires interconnection of sensors and actuators installed across the building, is well served by the LonWorks technology due to its high standards and flexibility features. + +Taylor & FrancisPresented on: International Journal of Solar Energypeer-reviewedBibliographic citation: D.

Research in several fields of traffic applications has resulted in a wealth of video processing and analysis methods. Two of the most demanding and widely studied applications relate to traffic monitoring and automatic vehicle guidance. In general, systems developed for these areas must integrate, amongst their other tasks, the analysis of their static environment (automatic lane finding) and the detection of static or moving obstacles (object detection) within their space of interest. In this paper we present an overview of image processing and analysis tools used in these applications and we relate these tools with complete systems developed for specific traffic applications. More specifically, we categorize processing methods based on the intrinsic organization of their input data (feature-driven, area-driven, or model-based) and the domain of processing (spatial/frame or temporal/video). Furthermore, we discriminate between the cases of static and mobile camera. Based on this categorization of processing tools, we present representative systems that have been deployed for operation. Thus, the purpose of the paper is threefold. First, to classify image-processing methods used in traffic applications. Second, to provide the advantages and disadvantages of these algorithms. Third, from this integrated consideration, to attempt an evaluation of shortcomings and general needs in this field of active research.ElsevierPresented on: Image and Vision Computingpeer-reviewedBibliographic citation: V.

However, in some EU regions solar applications, and especially the innovative ones (such as solar heating/cooling, solar drying, solar-powered desalination), remain at an early stage. The degree of development of each market does not depend on climate conditions (e.g., insolation) or on different technological developments. The major strengths, weaknesses, opportunities and threats of STTs are examined, in order to identify the most important actions that should be taken to reduce existing barriers, as opposed to RTD (Research and Technology Development) of the new STTs. These include financing schemes, publications, electronic dissemination tools, campaigns, events, creation of information centres, audits and studies.PergamonPresented on: Journal of Renewable Energypeer-reviewedBibliographic citation: T.

The existing BMS techniques are examined in this paper and a new design methodology for a generalized reliable BMS is proposed. The main advantage of the proposed BMS compared to the existing systems is that it provides a fault-tolerant capability and battery protection. The proposed BMS consists of a number of smart battery modules (SBMs) each of which provides battery equalization, monitoring, and battery protection to a string of battery cells. An evaluation SBM was developed and tested in the laboratory and experimental results verify the theoretical expectations.Institute of Electrical and Electronics EngineersPresented on: IEEE Transactions on Industrial Electronicspeer-reviewedBibliographic citation: J.

Therefore, there is great interest in the development, investigation and use of binders alternatives to Portland cement. Natural hydraulic lime (NHL) binders have become nowadays materials with high added value, due to their advantages in various construction applications. Some of them include compatibility, suitability, workability and the versatility in applications. NHL binders are made from limestones which contain sufficient argillaceous or siliceous components fired at relatively low temperatures, with reduction to powder by slaking with or without grinding. This study is focused in developing technology for small-scale production of cementitious binders, combining the knowledge and experience of geologists and mineral resources engineers. The first step of investigation includes field techniques to the study the lithology, texture and sedimentary structure of Neogene carbonate sediments, from various basins of Crete Island, Greece and the construction of 3D geological models, in order to determine the deposits of each different geological formation. Sampling of appropriate quantity of raw materials is crucial for the investigation. Petrographic studies on the basis of the study of grain type, grain size, types of porosity and depositional texture, are necessary to classify effectively industrial mineral raw materials for this kind of application. Laboratory tests should also include the study of mineralogical and chemical composition of the bulk raw materials, as well as the content of insoluble limestone impurities, thus determining the amount of active clay and silica components required to produce binders of different degree of hydraulicity. Firing of the samples in various temperatures and time conditions, followed by X-ray diffraction analysis and slaking rate tests of the produced binders, is essential to insure the beneficiation of their behavior. Beneficiation is defined as the implementation of the best available techniques to insure the production of an economically usable final product which combines both the hydraulicity of the silicates, aluminates and ferrites, as well as the reactivity of the calcium oxide amounts that are present. + +Investigation of carbonate rocks appropriate for the production of natural hydraulic lime binders (PDF Download Available).

The method is based on differences in the X-ray diffraction (XRD) patterns of the three smectites after (a) heating at 500°C for 90 min and (b) glycerol solvation of the Cs-forms of the smectites for 20 h. After heating at 500°C, well below the dehydroxylation temperature of the three smectites, saponite and hectorite re-expand upon ethylene glycol (EG) solvation, whereas stevensite layers remain collapsed. Saponite forms one-layer and hectorite two-layer complexes after Cs-saturation and glycerol solvation. Cs-stevensite displays a gradual increase in d 001 with increasing solvation time in glycerol vapours and forms two-layer glycerol complexes with prolonged solvation. Except for the individual Mg-smectites, the proposed method may be used to identify compositional heterogeneity that may exist in the smectites. Furthermore, it should be useful in identifying the individual trioctahedral Mg-smectites when present in mixtures, and in detecting interstratified layers of different Mg-trioctahedral smectites. Application of the method revealed that the SYnL-1 laponite (CMS Source Clay Project) is not homogeneous but consists of hectorite, stevensite and possibly mixed-layer hectorite/stevensite layers.Mineralogical SocietyPresented on: Clay Mineralspeer-reviewedBibliographic citation: G.

In the present work, the quality of El-Tih kaolin, Egypt, was investigated using the chemical/mineralogical characteristics as well as the field observations of the clay. Chemical analysis of major oxides was carried out using energy dispersive X-ray fluorescence (EDS-XRF) spectrometry. Mineralogical analyses were carried out using X-ray diffraction (XRD) and scanning electron microscopy coupled with wavelength-dispersive X-ray spectroscopy (SEM-WDS). Spatial heterogeneity of the quality was evaluated applying kriging geostatistical techniques and potential zones were identified. +Mineralogical SocietyPresented on: Clay Mineralspeer-reviewedBibliographic citation: A.

Volcanic and volcaniclastic rocks have variable concentrations of LIL elements (Ba, Sr, Rb, Th) and HFS elements (Zr, V) due to their mode of origin. The pyroclastic flows frequently show more or less intense devitrification, vapour-phase crystallization and, in some cases, evidence of fumarolic activity, as is indicated by the presence of scapolite. The volcanic and volcaniclastic rocks display various types of alteration including formation of zeolites (clinoptilolite, heulandite, mordenite, and laumontite) and smectite, as well as hydrothermal alteration (development of silicic, argillic, sericitic and propylitic zones) associated with polymetallic mineralization. The behaviour of chemical elements during alteration varies. Some are immobile and their distribution is controlled by the conditions prevailing during parent-rock formation and emplacement, but others, such as Ba and Sr, are mobile and selectively fractionate in zeolite extra-framework sites. The formation of zeolite from alteration of volcanic glass is accompanied by an increase in Mg and Al content, and a decrease in Si and Na content, whereas Ca is not affected by alteration. In certain pyroclastic flows, there is a significant difference in K-content between incipient glass and altered rock, due to K-feldspar formation during devitrification and vapour-phase crystallization. + +Presented on: Clay Mineralspeer-reviewedΒιβλιογραφική αναφορά: I.

The overestimation of layer charge by SF is based on assumptions +about the permanent CEC (CECperm) of smectites i) on the association of the molar mass of half unit cell (MHUC) with the CECperm of the smectitic +clay fraction and ii) on imbalanced SF calculated for a series of used smectites. The CECperm of smectites should not be determined at pH 4 +because of competitive adsorption of H+ cations at exchangeable sites. This was verified by monitoring the pH of acidified smectite suspensions. +Instead the pH at the isoelectric point (iep) should be used for determination of permanent charge of smectites. Moreover it is suggested that the +equation of Lagaly [Lagaly, G., 1994. Layer charge determination by alkylammonium ions. In: Mermut, A.R. (Ed.), Layer Charge Characteristics +of 2:1 Silicate Clay Minerals. CMS Workshop lectures, vol. 6.

The pyroclastic flow deposits frequently show intense devitrification, vapour-phase crystallization and evidence of fumarolic activity, which involves deposition of scapolite in pore spaces. The Feres basin can be subdivided on the basis of mineral alteration assemblages: (1) the Pefka region; characterized by intense hydrothermal alteration of the volcanic rocks and mineral zoning (silicic, arg illic, sericitic and propylitic zones) with polymetallic mineralization, and (2) the remainder of the basin; where the volcaniclastic rocks are characterized by the alteration of volcanic glass to zeolites (clinoptilolite, heulandite, mordenite, analcime), clay minerals (smectite, illite, celadonite, chlorite), SiO2 polymorphs (cristobalite, opal-CT, quartz), K-feldspar and calcite. Laumontite is also present as an alteration product of plagioclase, with stilbite sporadically occurring in veinlets. Locally, rhyolites are also altered to zeolites (clinoptilolite and/or mordenite). The zeolitization process has occurred rapidly with the depositional environment, temperature, rate of cooling (of the volcanic rocks), nature and temperature of the mineral-forming fluids and composition of the parent material controlling the formation of zeolites. + +Presented on: Mineralogical Magazinepeer-reviewedBibliographic citation: I.

Layer charge and charge distribution were determined by XRD using the LayerCharge program [Christidis, +G.E., Eberl, D.D., 2003. Determination of layer charge characteristics of smectites. Clays Clay Miner. 51, 644–655.]. The +rheological properties were determined, after sodium exchange using the optimum amount of Na2CO3, from free swelling tests. +Rheological properties were determined using 6.42% suspensions according to industrial practice. In smectites with layer charges +of −0.425 to −0.470 per half formula unit (phfu), layer charge is inversely correlated with free swelling, viscosity, gel strength, +yield strength and thixotropic behaviour. In these smectites, the rheological properties are directly associated with the proportion of +low charge layers. By contrast, in low charge and high charge smectites there is no systematic relation between layer charge or the +proportion of low charge layers and rheological properties. However, low charge smectites yield more viscous suspensions and +swell more than high charge smectites. The rheological properties of bentonites also are affected by the proportion of tetrahedral +charge (i.e. beidellitic charge), by the existence of fine-grained minerals having clay size, such as opal-CT and to a lesser degree by +the ionic strength and the pH of the suspension. A new method for classification of smectites according to the layer charge based on +the XRD characteristics of smecites is proposed, that also is consistent with variations in rheological properties. In this +classification scheme the term smectites with intermediate layer charge is proposed.ElsevierPresented on: Applied Clay Sciencepeer-reviewedBibliographic citation: G. E. Christidis , A. E.

Grinding +decreased the grain size of all three minerals. The crystallite size and structure of smectite was not +affected but the crystallite size of talc decreased.

Delamination of talc +crystallites was observed in the initial stages of grinding, whereas with more intense treatment, +amorphous material was formed. Comminution improved the colour properties of all three minerals, +namely brightness, L* (lightness) and DE*ab (deviation from perfect white diffuser). Grinding time +exerts greater influence on the reflectance from calcite surfaces than from clay minerals. This +difference is attributed to continuous formation of progressively smaller diffuse reflection units +forming a smoother calcite surface. Decrease of grain size does not form considerably smaller diffuse +reflection units in clay minerals unless delamination takes place.

The technique was tested using 29 well characterized smectites. According to their XRD +patterns, smectites were classified as group 1 (low-charge smectites) and group 2 (high-charge smectites). +The boundary between the two groups is at a layer charge of –0.46 equivalents per half unit-cell. Lowcharge +smectites are dominated by 17.1 AÊ layers, whereas high-charge smectites contain only 20% fully +expandable layers on average. Smectite properties and industrial applications may be dictated by the +proportion of 17.1 AÊ layers present. Non-expanding layers may control the behavior of smectites during +weathering, facilitating the formation of illite layers after subsequent cycles of wetting and drying. The +precision of the method is better than 3.5% at a layer charge of –0.50; therefore the method should be +useful for basic research and for industrial purposes.Clay Minerals SocietyPresented on: Clays and Clay Mineralspeer-reviewedBibliographic citation: G.

The study of the kinetics of adsorption showed that decolorization of maize oil is a first-order +process which occurs in two steps: a first fast step with higher activation energy (25.6 kJ mol –1), +indicating the influence of a chemical interaction between the pigment and the clay surface, followed by a +second slow step with low activation energy (12.3 kJ mol –1), characteristic of physical adsorption on the +previously adsorbed molecules. Decolorization of sunflower oil is also a first-order process, described by a +single mechanism with intermediate activation energy (19.0 kJ mol –1). Adsorption isotherms of +decolorization of maize oil follow the Freundlich equation, indicating the existence of heterogeneous +adsorption sites on the solid’s surface. Heterogeneity is attributed both to different active centers on the +smectite surface (Bro¨ nsted and Lewis centers) and to the different phases present in bentonite, such as +illitic layers and clinoptilolite, which also have active centers on their surfaces.Clay Minerals SocietyPresented on: Clays and Clay Mineralspeer-reviewedBibliographic citation: G.

Lime formation was monitored by means of kinetic curves and TTT diagrams. Particle size seems to control th onset of lime crystallization at low temperatures, but it is of minor importance at higher temparatures. With the experimental setting used, lime formation was completed at 900°C. The specific surface area of the end products increases with firing temperature up to 800°C, decreasing thereafter. Decrepitation of lime increases gradually with firing temperature. Hydration temperature during slaking increases rapidly up to 900°C being constant thereafter.

Although equilibrium is attained rapidly for all three metals, exchange is incomplete, with At(max) (maximum equilibrium fraction of the metal in the zeolite) being 0.95 for Pb, 0.76 for Zn, and 0.27 for Ni. In both Na ~ ␣89 and Na --* ␣89 exchange, the normalized selectivity coefficient is virtually constant for :~A~(normalized equilibrium fraction of the metal in the zeolite) values of --<0.6, suggesting a pronounced homogeneity of the available exchange sites. The Gibbs standard free energy, AG~ of the Na ---)␣89 exchange calculated from the normalized selectivity coefficient is -3.11 kJ eq and, for the Na ~ 1/2Znexchange, it is 2.75 kJ eq ~. +Examination of the solid exchange products with X-ray diffraction (XRD) revealed a possible decrease in crystallinity of zeolite Pb-Pc as suggested by the significant broadening and disappearance of diffraction lines. This decrease is associated with a reduction of pore opening, as indicated from Fourier-transform infrared analysis (FTIR), which in turn results in a decrease of the amount of zeolitic water. Thermogra- vimetric-differential thermogravimetric (TG-DTG) analysis showed that water loss occurs in three steps, the relative significance of which depends on the type of exchangeable cation and subsequently on the type of complex formed with the cation and/or the zeolite channels. Zeolite Na-Pc might be utilized in environmental applications, such as the treatment of acid-mine drainage and electroplating effluents.Clay Minerals SocietyPresented on: Clays and Clay Mineralspeer-reviewedBibliographic citation: G.E.

Testing included measurement of CEC (cation exchange capacity), swelling capacity, pH, rheological properties and some important foundry properties including green and dry compression strength, shatter index, wet tensile strength, compactability and permeability. The rheological and foundry properties are mainly influenced by the bentonite grade (smectite content) and the degree of disaggregation of the smectite quasicrystals due to the nature of the interlayer cation, the presence of mordenite and undevitrified glass shards, the degree of the oxidation of iron and the type of smectite–opal-CT interaction. Na-activation improves green compressive strength and especially wet tensile strength and decreases permeability, while its influence on the remaining foundry properties is unpredictable. Swelling properties are affected by bentonite grade, expressed by CEC, and the presence of characteristic phases (glass shards and opal-CT) decreases swelling, while zeolites increase CEC. The swelling capacity is closely related to the CEC, if smectite chemistry is controlled. It is shown that although the presence of zeolites like mordenite or small amounts of opal-CT may not affect rheological properties, the bonding properties always deteriorate. However, the presence of undevitrified glass reduces viscosity. + +ElsevierPresented on: Applied Clay Sciencepeer-reviewedBibliographic citation: G. E.

The activated materials have been rendered suitable for decolorization (bleaching) of rapeseed oil through removal of β-carotene. The optimum bleaching capacity is not associated with maximum surface area. Activation is characterized by destruction of the original smectite structure, removal of octahedral cations, uptake of OH− and formation of au amorphous Si-rich phase. Mg is the most readily removed element affecting the tendency for activation. The Otay-type montmorillonites are activated. more easily. Optimum conditions for activation are obtained using a variety of combinations of acid strength and residence time. The combination which is likely to be preferred on an industrial scale, is the least energy consuming. Therefore shorter treatments with more dilute acid are preferable. + +ElsevierPresented on: Applied Clay Sciencepeer-reviewedBibliographic citation: G.E. Christidis ,P.W. Scott ,A.C.

They contain opal-CT and, sometimes, zeolite along with smectite, and have been derived from the alteration of +rhyolitic volcanic rocks. The Miloan white bentonites contain Tatatilla-type montmorillonite and beidellite. The Kimolian +ones have Chambers-type montmorillonite. The alteration process involved removal of alkalis and uptake of Mg, probably from +sea water. Si is either redistributed or partially removed. The Kimolian white bentonites have higher brightnesses, L* and whiteness index values, and lower yellowness index and ΔE*ab values compared with the Miloan ones. The variations in white colour are inversely related to the abundance of Fe oxides +and anatase, the occurrence of Fe in the smectite structure and its oxidation state. The presence of silica minerals is not +an important factor affecting colour, but is undesirable since it imparts high abrasiveness in commercial products. The formation +of white bentonites of high quality requires the removal of alkalis and silica during alteration of acid volcanics in order +to avoid crystallization of zeolites and opal-CT. Fe needs to be incorporated into the smectite structure. Such conditions +are rarely attained. Springer VerlagPresented on: Mineralium Depositapeer-reviewedBibliographic citation: G.E.

The size of the constituents of a colloid plume is an important factor affecting the partitioning of dense colloids +at the bifurcation.

We considered the miscible displacement of a fluid initially free of particles by +another fluid containing particles of finite size in suspension within a fracture formed by two semi-infinite parallel plates. Particle spreading +occurs due to the combined actions of molecular diffusion and the dispersive effect of the Poiseuille velocity profile. Unlike Taylor dispersion, +here the finite size of the particles is taken into account. It is shown that because the finite size of a particle excludes it from the slowest +moving portion of the velocity profile, the effective particle velocity is increased, while the overall particle dispersion is reduced. A similar +derivation applied to particles flowing in uniform tubes yields analogous results. The effective velocity and dispersion coefficient derived in +this work for particle transport in fractures with uniform aperture are unique and ideally suited for use in particle tracking models.Παρουσιάστηκε στο: Journal of Colloid and Interface Sciencepeer-reviewedBibliographic citation: S.C.

The contaminant is assumed to decay, and sorb on to fracture surfaces and on to colloidal particles, as well as to diffuse into the rock matrix; whereas, colloids are envisioned to deposit irreversibly on to fracture surfaces without penetration into the rock matrix. The governing one-dimensional equations describing the contaminant and the colloid transport in the fracture, colloid deposition on to fracture surfaces, and contaminant diffusion into the rock matrix are coupled. This coupling is accomplished by assuming that the amount of contaminant mass captured by colloidal particles in solution and the amount captured by deposited colloids on fracture surfaces are described by modified Freundlich reversible equilibrium sorption relationships, and that mass transport by diffusion into the rock matrix is a first-order process. The contaminant sorption on to fracture surfaces is described by a linear equilibrium sorption isotherm, while the deposition of colloids is incorporated into the model as a first-order process. The resulting coupled contaminant transport non-linear equation is solved numerically with the fully implicit finite difference method. The constant concentration as well as the constant flux boundary conditions have been considered. The impact of the presence of colloids on contaminant transport is examined. According to model simulations the results show that, depending on the conditions of the physical system considered, colloids can increase or decrease the mobility of contaminants. +Παρουσιάστηκε στο: Journal of Hydrologypeer-reviewedBibliographic citation: A.

A smaller time step yields an increasingly accurate, yet +more computationally demanding solution. Selection of this time step becomes an important consideration and, depending on the +complexity of the problem, a single optimum value may not exist. The characteristics of the system under consideration may be +such that a constant time step may yield solutions with insu cient accuracy in some portions of the domain and excess computation +time for others. In this work, new particle tracking equations speci%cally designed for the solution of problems associated with +di(usion processes in one, two, and three dimensions are presented. Instead of a constant time step, the proposed equations employ +a constant spatial step. Using a traditional particle tracking algorithm, the travel time necessary for a particle with a di(usion +coe cient inversely proportional to its diameter to achieve a pre-speci%ed distance was determined. Because the size of a particle +a(ects how it di(uses in a quiescent 8uid, it is expected that two di(erently sized particles would require di(erent travel times to +move a given distance. The probability densities of travel times for plumes of monodisperse particles were consistently found to +be log-normal in shape. The parameters describing this log-normal distribution, i.e., mean and standard deviation, are functions of +the distance speci%ed for travel and the di(usion coe cient of the particles. Thus, a random number selected from this distribution +approximates the time required for a given particle to travel a speci%ed distance. The new equations are straightforward and may be +easily incorporated into appropriate particle tracking algorithms. In addition, the new particle tracking equations are as accurate and +often more computationally e cient than the traditional particle tracking equationΠαρουσιάστηκε στο: Chemical Engineering Sciencepeer-reviewedBibliographic citation: S.

The aperture in the fracture plane is considered as a lognormally distributed random variable with spatial fluctuations described by an exponential autocovariance function. Colloids are envisioned to irreversibly deposit onto fracture surfaces without penetrating the rock matrix; whereas, the contaminant is assumed to decay, sorb onto fracture surfaces and onto colloidal particles, as well as to diffuse into the rock matrix. The governing stochastic transport equations are solved numerically for each realization of the aperture fluctuations by a fully implicit finite difference scheme. Emphasis is given on the effects of variable aperture on colloid and colloid-facilitated contaminant transport. Simulated breakthrough curves of ensemble averages of several realizations show enhanced colloid transport and more pronounced fingering when colloids are subject to size exclusion from regions of small aperture size. Moreover, it is shown that an increase in the fracture aperture fluctuations leads to faster transport and increases dispersion. For the case of contaminant/colloids cotransport it is shown, for the conditions considered in this work, that colloids enhance contaminant mobility and increase contaminant dispersion. + +Παρουσιάστηκε στο: Transport in Porous Mediapeer-reviewedBibliographic citation: C.

Dense colloids travel in +water-saturated fractures by advection and diffusion while subject to the influence of gravity. Colloids +are assumed to neither attach onto the fracture walls nor penetrate the rock matrix based on the assumptions +that they are inert and their size is larger than the pore size of the surrounding solid matrix. Both +the size distribution of a colloid plume and colloid density are shown to be significant factors impacting +their transport when gravitational forces are important. A constant-spatial-step particle-tracking code +simulates colloid plumes with increasing densities transporting in water-saturated fractures while +accounting for three forces acting on each particle: a deterministic advective force due to the Poiseuille +flow field within the fracture, a random force caused by Brownian diffusion, and the gravitational force. +Integer angles of fracture orientation with respect to the horizontal ranging from ±90 are considered: +three lognormally distributed colloid plumes with mean particle size of 1 lm (averaged on a volumetric +basis) and standard deviation of 0.6, 1.2 and 1.8 lm are examined. Colloid plumes are assigned densities +of 1.25, 1.5, 1.75 and 2.0 g/cm3. The first four spatial moments and the first two temporal moments are +estimated as functions of fracture orientation angle and colloid density.

The fracture is assumed to possess a spatially +variable aperture in its two-dimensional plane, whereas the rock matrix is treated as a +two-dimensional homogeneous and tight porous medium. The aperture fluctuations in the +fracture plane are described stochastically. Moisture exchange between the fracture and +the rock matrix is accounted for via an advective coupling term that governs the transfer +of moisture at the fracture-matrix interface and takes into account the effect of a fracturesurface +coating material. Although the variable aperture fracture is two-dimensional, the +coupling term between the fracture and the rock matrix accounts for the threedimensional +nature of the physical system. The stochastic nonlinear set of partial +differential equations is solved numerically by the Galerkin finite element method in +conjunction with the Picard iterative scheme and an automatic time step marching. +Simulations are performed to investigate phenomena which have been ignored in previous +studies. It is demonstrated that, for the case of no moisture exchange with the rock matrix, +the moisture follows preferential flow paths within the fracture plane and exhibits +pronounced fingering effects. Furthermore, it is shown that the larger the fracture +aperture fluctuations the more extended the moisture flow in the fracture. In addition, for +the case where there exists moisture exchange with the rock matrix, the movement of the +moisture front is considerably reduced, whereas fracture-surface coatings tend to slow +down moisture absorption by the rock matrix.Παρουσιάστηκε στο: Water resource researchpeer-reviewedBibliographic citation: A.

Systematic variation of the major chemical +elements reveals that the deposits were formed from different precursors which were erupted from different +volcanic centers belonging to at least two separate volcanic provinces. The volcanic eruptions were +probably subaqueous. The major authigenic phases are smectite, K-feldspar, opal-CT and the zeolites +mordenite and clinoptilolite. The deposits have a complex history and have been affected by hydrothermal +alteration. +The geological features ofbentonites coupled by the presence of abundant authigenic K-feldspar indicate +that alteration of the parent volcanoclastic rocks took place under low temperatures and is probably not +related to hydrothermal alteration, which is a separate event. Hydrothermal alteration has modified both +the mineralogical characteristics and the properties of bentonites. Alteration of the parent rocks to bentonites +was favoured by high water : wall rock ratios and fluid flow and is associated with leaching and +subsequent removal of Na, K and Ca. The source of Mg was the parent rocks and only small scale Mguptake +from the sea water has probably taken place. The formation of authigenic K-feldspar has probably +been favoured by a high K§ + activity ratio and high Si activity of the pore fluid.

The product K-bentonite which contains illite/smectite, kaolinite, K-feldspar, +quartz, sulphates and sulphides exhibits an unusual tendency for increase of expandability with depth. +Mineralogy and I/S textures were determined with X-ray diffraction and SEM and TEM methods +respectively and chemistry using X-ray fluorescence. Illitization is characterized by a 5- to 6-fold increase +of K and release of Si, Fe, Mg Na, and Ca from the parent rock, indicating a K-influx (K-metasomatism) +in the system. +The I/S particle morphology is characterized by both flaky and lath-like particles, the former dominating +in the range 100-50% expandable layers (R0 ordering) and the latter in the range 50-10% expandable +layers (R1 and R > 1 ordering). Flaky particles are also abundant in samples with R1 ordering and +abundant kaolinite, indicating that the latter might affect illitization. The I/S particles are classified in +populations with thickness multiples of 10 A, their thickness being probably smaller than the coherent +XRD domain. As the reaction proceeds, particles grow thicker and more equant. The distribution of I/S +particle dimensions forms steady state profiles showing log-normal distribution; however, sensu stricto +Ostwald ripening is unlikely. It seems that the reaction proceeds toward minimization of the surface free +energy of I/S, being affected principally by temperature and K-availability. The spatial distribution of +expandability implies that the heating source was probably a mineralized vein with T < 200~ directed +away from the bentonite, suggesting that illitization might be used as an exploration guide for mineral +deposits.Clay Minerals SocietyPresented on: Clays and Clay Mineralspeer-reviewedBibliographic citation: G.E.

In this environment, organizations and companies adopt the Linked Data practices utilizing Semantic Web (SW) technologies, in order to publish their data and offer SPARQL endpoints (i.e., SPARQL-based search services). On the other hand, the dominant standard for information exchange in the Web today is XML. Additionally, many international standards (e.g., Dublin Core, MPEG-7, METS, TEI, IEEE LOM) in several domains (e.g., Digital Libraries, GIS, Multimedia, e-Learning) have been expressed in XML Schema. The aforementioned have led to an increasing emphasis on XML data, accessed using the XQuery query language. The SW and XML worlds and their developed infrastructures are based on different data models, semantics and query languages. Thus, it is crucial to develop interoperability mechanisms that allow the Web of Data users to access XML datasets, using SPARQL, from their own working environments. It is unrealistic to expect that all the existing legacy data (e.g., Relational, XML, etc.) will be transformed into SW data. Therefore, publishing legacy data as Linked Data and providing SPARQL endpoints over them has become a major research challenge. In this direction, we introduce the SPARQL2XQuery Framework which creates an interoperable environment, where SPARQL queries are automatically translated to XQuery queries, in order to access XML data across the Web. The SPARQL2XQuery Framework provides a mapping model for the expression of OWL–RDF/S to XML Schema mappings as well as a method for SPARQL to XQuery translation. To this end, our Framework supports both manual and automatic mapping specification between ontologies and XML Schemas. In the automatic mapping specification scenario, the SPARQL2XQuery exploits the XS2OWL component which transforms XML Schemas into OWL ontologies. Finally, extensive experiments have been conducted in order to evaluate the schema transformation, mapping generation, query translation and query evaluation efficiency, using both real and synthetic datasets.Springer VerlagPresented on: World Wide Webnon peer-reviewedBibliographic citation: G.Skevakis , K.Makris , V.Kalokyri , P.

Design/methodology/approach – The observations are automatically associated with contextual metadata that allow them to be visualized on top of 2D or 3D maps. The observations are managed by a multimedia management system, and annotated by the same and/or other users with common interests. Annotations made by the crowd support the knowledge distillation of the data and data provenance processes in the system. Findings – MoM-NOCS is complementary and interoperable with systems that are managed by natural history museums like MMAT (Makris et al., 2013) and biodiversity metadata management systems like BIOCASE (BioCASE) and GBIF (GBIF) so that they can link to interesting observations in the system, and the statistics of the observations that they manage can be visualized by the software. Originality/value – The Framework offers rich functionality for visualizing the observations made by the crowd as function of time.EmeraldPresented on: International Journal of Pervasive Computing and Communicationspeer-reviewedBibliographic citation: G.

They allow wireless connection to computers and the images can be automatically transferred to a PC or can be integrated into a GIS system. In this paper, we present an approach for personalised spatial information retrieval and visualisation for picture databases using ontologies and semantic maps. Ontologies are used in our case to describe domain knowledge in relation to spatial coordinates, to enhance image annotation, search capability and information visualisation. Individuals from the ontologies are represented by their footprint in semantic maps. Personalised semantic maps are constructed selecting ontologies, concept types or individuals that reflect the interests of the user. We describe a developed prototype system with a database design for ontologies and semantic maps. We demonstrate the automatic image annotation and the visualisation of the spatial queries. An application of the system targets the area of culture and tourism and provides a user friendly interface.Παρουσιάστηκε στο: International Journal of Digital Culture and Electronic Tourismpeer-reviewedBibliographic citation: S.Christodoulakis , M.Foukarakis, , L.

The MP7QL has the MPEG-7 as +data model and allows for querying every aspect of an MPEG-7 multimedia content description. It allows the users to express +the conditions that should hold for the multimedia content returned to them regarding semantics, low-level visual and audio +features and media-related aspects. The MP7QL queries may utilize the users’ FASP and Usage History as context, thus allowing +for personalized multimedia content retrieval. The FASP model supported is compatible with the MP7QL and has the model of +the standard MPEG-7 FASPs as a special case. The proposed FASPs essentially are MP7QL queries. Both the MP7QL and its compatible +FASP model allow for the exploitation of domain knowledge encoded using pure MPEG-7 constructs. In addition, they allow the +explicit specification of boolean operators and/or preference values in order to allow both the combination of the query conditions +according to the user intentions and the expression of the importance of the individual conditions for the users. The MP7QL +query results are represented as MPEG-7 documents, guaranteeing the closure of the results within the MPEG-7 space. The MP7QL +and the FASP model have been expressed using both XML Schema and OWL syntax. An implementation of the MP7QL, on top of an +XML Native Database is currently in progress. A real world-world evaluation study on the expressive power of the MP7QL shows +that it covers both general purpose and domain specific requirements in multimedia content retrieval.

The use of well-accepted standards is of paramount importance for interoperability support in open environments. In addition, the semantic description of multimedia content utilizing domain ontologies is very useful for indexing, query specification, retrieval, filtering, user Interfaces, and knowledge extraction from audiovisual material. With the MPEG-7 and MPEG-21 standards dominating the multimedia content and service description domain and OWL dominating the ontology description languages, it is important to establish a framework that allows these standards to interoperate. We describe here the DS-MIRF framework, a software engineering framework that facilitates the development of knowledge-based multimedia applications such as multimedia information retrieval, filtering, browsing, interaction, knowledge extraction, segmentation, and content description. DS-MIRF supports interoperability of OWL with the MPEG-7/21 so that domain and application ontologies expressed in OWL can be transparently integrated with MPEG-7/21 metadata. This allows applications that recognize and use the constructs provided by MPEG-7/21 to make use of domain and application ontologies, resulting in more effective retrieval and user interaction with the audiovisual material.Institute of Electrical and Electronics EngineersPresented on: IEEE Transactions on Knowledge and Data Engineeringpeer-reviewedBibliographic citation: C.

Our work aims to provide a methodology to enhance the retrieval effectiveness of audiovisual content, while maintaining compatibility with the international multimedia standards. +In our framework, domain-specific ontologies guide the definition of both the application-specific metadata and the instance-description metadata that describe the contents of audiovisual programs and/or their segments. The ontologies are also used in order to provide compatible descriptions in both audiovisual content standards (MPEG-7 and TV-Anytime) for the same content. This approach allows indexing compatibility and interoperability of TV-Anytime and digital library applications. +We describe the design and implementation of a system supporting this framework. The components of the system include a segmentation tool for segmenting audiovisual information, which also provides ontology-based semantic indexing capabilities, and an appropriate API for semantic query support. An application testbed for the domain of soccer games has been developed on top of this system. An ontology for soccer games has been defined and used for indexing and retrieval of soccer games that have been stored in the system database. +The methodology we developed opens up a wide opportunity for the creation of MPEG-7 and TV-Anytime services offering structured domain-specific ontologies that can be integrated to these standards for enhancing audiovisual content retrieval performance.

Solutions to this problem have been reported for some widely available disk technologies, such as magnetic CAV and optical CLV disks. However, important new technologies such as multizoned magnetic disks, have been recently introduced. For such technologies no formal solution to the ODP problem has been reported. In this paper, we first identify the fundamental characteristics of disk-device technologies which influence the solution to the ODP problem. We develop a comprehensive solution to the problem that covers all currently available disk technologies. We show how our comprehensive solution can be reduced to the solutions for existing disk technologies, contributing thus a solution to the ODP problem for multizoned disks. Our analytical solution has been validated through simulations and through its reduction to the known solutions for particular disksIEEEPresented on: IEEE Transactions on Knowledge and Data Engineeringpeer-reviewedBibliographic citation: C.

The errors that exist in the histogram approximations directly or transitively affect many estimates derived by the database system. We identify the class of serial histograms and its subclass of end-btased histograms; the latter is of particular interest because such histograms are used in several database systems. We concentrate on equality join queries without function symbols where each relation is joined on the same attribute(s) for all joins in which it participates. Join queries of this restricted type are called t-cllque queries. We show that the optimal histogram for reducing the worst-case error in the result size of such a query is always serial. For queries with one join and no function symbols (all of which are vacuously t-clique queries), we present results on finding the optimal serial histogram and the optimal end-biased histogram based on the query characteristics and the frequency distributions of values in the join attributes of the query relations. Finally, we prove that for t-clique queries with a very large number of joins, h~gh-bzased h zstograms (which form a subclass of end-biased histograms) are always optimal. To construct a histogram for the join attribute(s) of a relation, the values in the attribute(s) must first be sorted based on their frequency and then assigned into buckets according to the optimality results above. + +Presented on: ACM Transactions on Database Systemspeer-reviewedBibliographic citation: Y.

Delay-sensitive data include digital audio, animations, and video. Retrieval of these data types from secondary storage has to satisfy certain time constraints in order to be acceptable to the user. The presentation is based on digital audio in order to provide intuition to the reader, although the results are applicable to all delay-sensitive data. A theoretical framework is developed for the real-time requirements of digital audio playback. We show how to describe these requirements in terms of the consumption rate of the audio data and the nature of the data-retrieval rate from secondary storage. Making use of this framework, bounds are derived for buffer space requirements for certain common retrieval scenarios. Storage placement strategies for multichannel synchronized data are then categorized and examined. The results presented in this paper are basic to any playback of delay-sensitive data and should assist the multimedia system designer in estimating hardware requirements and in evaluating possible design choices.Association for Computing MachineryPresented on: ACM Transactions on Information Systemspeer-reviewedBibliographic citation: J.

Since objects frequently involve diverse data types (such as text, compressed images, graphics, etc.) as well as composite structures, they may have a largely variable length. In this paper, we assume that in the case of composite objects their components are clustered together and that object file organizations have overflows. The blocks of the main file are grouped so that they share a common number of overflow blocks. For this class of file organizations we present and analyze the performance of three different overflow searching algorithms. We show that the third algorithm gives very significant performance advantages under certain circumstances. + +Presented on: Information Systemspeer-reviewedBibliographic citation: Y.

Above all, they need to develop their own competencies and critical thinking on games. The overarching framework for a fruitful answer to this challenge could be structured around a particular type of literacy, the so-called gaming literacy. This new type of literacy seeks to provide a firm ground for cultivating a new type of thinking about the world that is more close to the children's way of thinking: “What does the world look like from the point of view of gaming?” To enable educators effectively move towards this direction, it is important to formalize the professional knowledge and skills they need to develop, offer new learning opportunities for them (either pre-service or in-service) and build communities of practice within which they could exchange their experiences and continue their professional development. We present our work towards this direction, the underlying learning framework, its initial conception, the first pilot implementation and directions of further developments focusing on mobile games.Παρουσιάστηκε στο: International Conference on Interactive Mobile Communication Technologies and Learning (IMCL) 2014 IEEEBibliographic citation: N.Moumoutzis , M.Christoulakis , A.Pitsiladis , G.

The colloids used in these experiments +were bacteriophage MS2 (0.025 mm), and 0.05- and 3-mm spherical polystyrene beads, and +were compared with a conservative nonsorbing tracer (KCl). The results show that early +breakthrough of colloids increases with colloid size and water velocity, compared with the +tracer. These results are in line with our previous observations at the pore scale that +indicated that larger colloids are restricted by the size exclusion effect from sampling all +paths, and therefore they tend to disperse less and move in the faster streamlines, if they +are not filtered out. The measured macroscopic dispersion coefficient decreases with +colloid size due to the preferential flow paths, as observed at the pore scale. Dispersivity, +typically considered only a property of the medium, is in this case also a function of +colloid size, in particular at low Peclet numbers due to the size exclusion effect. Other +parameters for colloid transport, such as collector efficiency and colloid filtration rates, +were also estimated from the experimental breakthrough curve using a numerical fitting +routine.

The solution is developed for a third- or flux-type inlet boundary condition, which is applicable when considering resident (volume-averaged) solute concentrations, and a semi-infinite porous medium. For mathematical simplicity it is hypothesized that the sorption processes are based on linear equilibrium isotherms and that the local chemical equilibrium assumption is valid. The results from several simulations, compared with predictions based on the classical advection-dispersion equation with constant coefficients, indicate that at early times, spatially variable retardation affects the transport behavior of sorbing solutes. The zeroth moments corresponding to constant and variable retardation are not necessarily equal. The impact of spatially variable retardation increases with increasing Péclet number. + +Παρουσιάστηκε στο: Water Resources Researchpeer-reviewedBibliographic citation: C. V. Chrysikopoulos ,P. K.

A semianalytical and an approximate analytical solution were derived to the one-dimensional advection-dispersion equation for a semi-infinite medium under local equilibrium conditions, with a flux-type inlet boundary condition accounting for solute recirculation between the extraction-injection well pair. Solutions were obtained by taking Laplace transforms to the equations with respect to time and space. The semianalytical solution is presented in Laplace domain and requires numerical inversion, while the approximate analytical solution is given in terms of a series of simple nested convolution integrals which are easily determined by numerical integration techniques. The applicability of the well-to-well recirculation model is limited to field situations where the actual flow field is one dimensional or where an induced flow field is obtained such that the streamlines in the neighborhood of the monitoring wells are nearly parallel. However, the model is fully applicable to studies of solute transport through packed columns with recirculation under controlled laboratory conditions. + +Παρουσιάστηκε στο: Water Resources Researchpeer-reviewedBibliographic citation: C.

The solutions are suitable for homogeneous porous media with unidirectional interstitial velocity. The dissolved solute may undergo first-order decay or may sorb under local equilibrium conditions. The solutions are obtained for rectangular and elliptic as well as circular source geometries, assuming that the dissolution process is mass transfer limited, by applying Laplace and Fourier transforms. Although the solutions contain integral expressions, these integrals are easily evaluated numerically. These solutions are useful for verifying the accuracy of numerical solutions to more comprehensive models and for design and interpretation of experiments in laboratory-packed beds and possibly some field studies. The results of several simulations indicate that for short downstream distances, predictions of contaminant concentrations are sensitive to the source structure and orientation with respect to the direction of interstitial flow . + +Παρουσιάστηκε στο: Water Resources Research peer-reviewedΒιβλιογραφική αναφορά: C.

The porous medium is considered to possess spatially periodic geochemical characteristics in all three directions, where the spatial periods define a rectangular parallelepiped or a unit-element. The spatially-variable geochemical parameters of the solid matrix are incorporated into the transport equation by a spatially-periodic distribution coefficient and consequently a spatially-periodic retardation factor. Expressions for the effective or large-time coefficients governing the macroscopic solute transport are derived for solute sorbing according to a linear equilibrium isotherm as well as for the case of a first-order kinetic sorption relationship. The results indicate that for the case of a chemical equilibrium sorption isotherm the longitudinal macrodispersion incorporates a second term that accounts for the eflect of averaging the distribution coefficient over the volume of a unit element. Furthermore, for the case of a kinetic sorption relation, the longitudinal macrodispersion expression includes a third term that accounts for the effect of the first-order sorption rate. Therefore, increased solute spreading is expected if the local chemical equilibrium assumption is not valid. The derived expressions of the apparent parameters governing the macroscopic solute transport under local equilibrium conditions agreed reasonably with the results of numerical computations using particle tracking techniques. + +Kluwer Academic PublishersΠαρουσιάστηκε στο: Transport in Porous Media peer-reviewedBibliographic citation: C.

Bacteriophages +MS2 and X174 were used as model viruses, kaolinite (kGa-1b) and montmorillonite (STx-1b) +as model clay colloids, and glass beads as model packing material. The combined and synergistic effects +of clay colloids and pore water velocity on virus transport and retention in porous media were examined +at three pore water velocities (0.38, 0.74, and 1.21 cm/min). The results indicated that the mass recovery +of viruses and clay colloids decreased as the pore water velocity decreased; whereas, for the cotransport +experiments no clear trend was observed. Temporal moments of the breakthrough concentrations suggested +that the presence of clays significantly influenced virus transport and irreversible deposition onto +glass beads. Mass recovery values for both viruses, calculated based on total virus concentration in the +effluent, were reduced compared to those in the absence of clays. The transport of both suspended and +attached onto suspended clay-particles viruses was retarded, compared to the tracer, only at the highest +pore water velocity. Moreover both clay colloids were shown to hinder virus transport at the highest pore +water velocity.

The fracture plane is partitioned into unit elements with different apertures generated stochastically from a log-normal distribution. The model also accounts for colloid size exclusion from fracture elements with small apertures. Both equilibrium and kinetic colloid deposition onto fracture surfaces are investigated. Colloid surface exclusion is incorporated in the dynamics of kinetic deposition. The impact of deposited colloids on further colloid deposition is described by either a linear or a non-linear blocking function. The resulting system of governing partial differential equations is solved numerically using the fully implicit finite difference method. Model simulations illustrate the presence of preferential colloid transport in the fracture plane. It is shown that size exclusion increases the dispersion of colloids and leads to earlier breakthrough, especially for large-size particles. Furthermore, it is demonstrated that surface exclusion enhances colloid transport, and the assumption of clean-bed media may underestimate liquid-phase colloid concentrations. + +Presented on: Colloids and Surfaces A: Physicochemical and Engineering Aspectspeer-reviewedBibliographic citation: C.

The model aquifer comprised a packing of +homogeneous, medium-sized sand and conveyed steady, unidirectional flow. +Tetrachloroethene (PCE) pools were introduced within model aquifers atop glass- and +clay-lined aquifer bottoms. Transient breakthrough at an interstitial velocity of 7.2 cm/h, +and three-dimensional steady state concentration distributions at velocities ranging from +0.4 to 7.2 cm/h were monitored over periods of 59 and 71 days for the glass- and claybottom +experiments, respectively. Pool-averaged mass transfer coefficients were obtained +from the observations via a single-parameter fit using an analytical model formulated with +a second type boundary condition to describe pool dissolution [Chrysikopoulos, 1995]. +Other model parameters (interstitial velocity, longitudinal and transverse dispersion +coefficients, and pool geometry) were estimated independently. Simulated and observed +dissolution behavior agreed well, except for locations relatively close to the pool or the +glass-bottom plate. Estimated mass transfer coefficients ranged from 0.15 to 0.22 cm/h, +increasing weakly with velocity toward a limiting value. Pool mass depletions of 31 and +43% for the glass- and clay-bottom experiments failed to produce observable changes in +the plumes and suggested that changes in pool interfacial area over the period of the +experiment were negligible. Dimensionless mass transfer behavior was quantified using a +modified Sherwood number (Sh*). Observed Sh* values were found to be about 2–3 +times greater than values predicted by an existing theoretical mass transfer correlation, +and 3–4 times greater than those estimated previously for an ideally configured +trichloroethene (TCE) pool (circular and smooth). It appeared that the analytical model’s +failure to account for pore-scale pool-water interfacial characteristics and larger scale pool +shape irregularities biased the Sh* estimates toward greater valuesΠαρουσιάστηκε στο: Water Resources Research peer-reviewedBibliographic citation: B.

An idealized three-dimensional porous formation of infinite domain with spatially periodic retardation factor, velocity field, and microdispersion coefficients in all three directions was considered. Sorption was assumed to be governed by a linear equilibrium isotherm under local chemical equilibrium conditions. The analytical expressions presented are based on a perturbation method where all of the spatially periodic parameters employed were assumed to have ``small'' fluctuations. It was shown that the effective velocity vector is given by the volume-averaged interstitial velocity vector divided by the volume-averaged retardation factor, and the effective dispersion dyadic (second-order tensor) is given by the volume-averaged microdispersion dyadic divided by the volume-averaged dimensionless retardation factor plus a dyadic expressing the increase in solute spreading caused by the spatial variability of the parameters. + +Παρουσιάστηκε στο: Water Resources Researchpeer-reviewedBibliographic citation: C.

Biosorption +is a promising, low cost, and environmentally friendly clean up technique. Malt spent rootlets (MSR), a +brewery by-product, were used as sorbents for the removal of mercury from aquatic systems. The effect +of the solution pH, contact time between sorbent, solid to liquid ratio, and initial mercury concentration +on mercury removal were investigated experimentally. It was found that the optimum pH for the mercury +sorption onto MSR was approximately 5. Sorption kinetic experiments revealed that mercury sorption +is a relatively rapid process, where film diffusion and intra-particle diffusion play an important role. +The kinetic data were successfully described by both the pseudo-second-order and Elovich models. The +isotherm data were adequately fitted by the Langmuir model determining a monolayer capacity qmax +equal to 50 mg/g and suggesting a functional group-limited sorption process. MSR were capable of +removing significant amounts of mercury, mainly due to the carboxyl and phosphonate groups of their +surfaces.Παρουσιάστηκε στο: The Chemical Engineering Journalpeer-reviewedBibliographic citation: V.

They +have also been used as viral indicators in environmental systems. Coliphages (e.g., MS2, ΦX174) have also +been studied as indicators of viral pollution in fecally contaminated water. Our objective was to evaluate the +distribution of three viral fecal indicators (hAdVs, MS2, and ΦΧ174), between two different phyllosilicate clays +(kaolinite and bentonite) and the aqueous phase. A series of static and dynamic experiments were conducted +under two different temperatures (4, 25 °C) for a time period of seven days. HAdV adsorption was examined +in DNase I reaction buffer (pH=7.6, and ionic strength (IS)=1.4 mM), whereas coliphage adsorption in phosphate +buffered saline solution (pH=7, IS=2 mM). Moreover, the effect of IS on hAdV adsorption under static +conditions was evaluated. The adsorption of hAdVwas assessed by real-time PCR and its infectivitywas tested by +cultivation methods. The coliphages MS2 and ΦΧ174 were assayed by the double-layer overlay method. The +experimental results have shown that coliphage adsorption onto both kaolinite and bentonite was higher for +the dynamic than the static experiments; whereas hAdV adsorption was lower under dynamic conditions. The +adsorption of hAdV increased with decreasing temperature, contrary to the results obtained for the coliphages. +This study examines the combined effect of temperature, agitation, clay type, and IS on hAdV adsorption onto +clays.

For the special case of a monodisperse colloid +suspension the particle-tracking model is in perfect agreement with predictions based on +an existing analytical solution. It is shown that lognormal colloid size distributions exhibit +greater spreading than monodisperse suspensions. Increasing the fracture porosity of the +solid matrix leads to higher matrix diffusion, which in turn delays particle breakthrough +for both the monodisperse and variably sized colloid suspensions. The smallest particles of +a distribution are more greatly affected by matrix diffusion whereas the largest particles +are transported faster and further along a fracture. Both perfect sink and kinetic colloid +deposition onto fracture surfaces are examined. Kinetic deposition accounts for colloid +surface exclusion by either a linear or nonlinear blocking function. For both cases the +smallest colloid particles tend to preferentially deposit onto the fracture wall. Both matrix +diffusion and surface deposition tend to discretize colloid distributions according to +particle size so that larger particles are least retarded and smaller particles are more +slowly transported. Furthermore, it is shown that the rate of colloid deposition is inversely +proportional to the fracture aperture.Παρουσιάστηκε στο: Water Resources Researchpeer-reviewedBibliographic citation: S.C.

A kinetic isotherm describes contaminant sorption +onto colloids and sorbed contaminants assume the +unique transport properties of colloids. Sorption of the +contaminants that have diffused into the matrix is governed +by a first-order kinetic reaction.

To support +flow modeling at arbitrary resolution, three methods of parameter interpolation are described including piece-wise linear interpolation, +monotone piece-wise-cubic Hermitian interpolation, and universal kriging. The latter gives parameter estimates that +minimize the mean square error of the interpolator, and therefore can be used as a standard against which the accuracy of polynomial +methods can be assessed. Based on the application of these methods to a dataset describing cross-sectional properties at 283 +stations, piece-wise linear interpolation gives parameter estimates that closely track universal kriging estimates and therefore this +method is recommended for routine modeling purposes. Piece-wise-cubic interpolation gives parameter estimates that do not track +as well. Differences between cubic and kriging estimates were found to be 2–10 times larger than differences between linear and kriging +parameter estimates. In the context of one-dimensional flow modeling, the sensitivity of steady state water level predictions to +the channel bed interpolator is comparable to a 5% change in the Manning coefficient.Παρουσιάστηκε στο: Advances in Water Resourcespeer-reviewedBibliographic citation: Brett F.

Batch experiments were conducted in a flow-through electrolytic cell with internal recycle at voltage of 5, 7 +and 9V, NaCl concentrations of 1%, 2% and 4%, recirculation rates of 0.4 and 0.62 L/s and initial chemical oxygen +demand (COD) concentrations of 1475, 3060, 5180 and 6545 mg/L. The conversion of total phenols and COD as well as +the extent of decolorization generally increased with increasing voltage, salinity and recirculation rate and decreasing +initial concentration. In most cases, nearly complete degradation of phenols and decolorization were achieved at short +treatment times up to 60 min; this was accompanied by a relatively low COD removal that never exceeded 40% even +after prolonged (up to 240 min) times. The consumption of energy per unit mass of COD removed after 120 min of +treatment was found to be a strong function of the operating conditions and was generally low at high initial +concentrations and/or reduced salinity. The acute toxicity to marine bacteria Vibrio fischeri decreased slightly during +the early stages of the reaction and this was attributed to the removal of phenols. However, as the reaction proceeded +toxicity increased due to the formation of organochlorinated by-products as confirmed by GC/MS analysis. The +toxicity to Daphnia magna increased sharply at short treatment times and remained quite high even after prolonged +oxidation.PergamonΠαρουσιάστηκε στο: Water Researchpeer-reviewedBibliographic citation: M.

According to VALLME, dispersion of +microvolumes of a low density extractant organic solvent into the aqueous sample is achieved by using +for the first time vortex mixing, a mild emulsification procedure. The fine droplets formed could extract +target analytes towards equilibrium faster because of the shorter diffusion distance and larger specific +surface area. Upon centrifugation the floating extractant acceptor phase restored its initial single microdrop +shape and was used for high-performance liquid chromatographic analysis. Different experimental +parameters were controlled and the optimum conditions found were: 50l of octanol as the extractant +phase; 20 ml aqueous donor samples; a 2 min vortex extraction time with the vortex agitator set at a +2500rpm rotational speed; centrifugation for 2 min at 3500 rpm; no ionic strength or pH adjustment. +The calculated calibration curves gave high levels of linearity yielding correlation coefficients (r2) greater +than 0.9935. The repeatability and reproducibility of the proposed method were found to be good and +the limits of the detection were calculated in the low g l−1 level ranging between 0.01 and 0.07g l−1. +Matrix effects were determined by applying the proposed method to spiked tap, river water and treated +municipal wastewater samples.ElsevierΠαρουσιάστηκε στο: Talantapeer-reviewedBibliographic citation: E.

A Plackett–Burman design +for screening was carried out in order to determine the significant experimental conditions affecting the HS-SDME process (namely drop volume, +aqueous sample volume, stirring speed, ionic strength, extraction time and temperature), and then a central composite design was used to optimize +the significant conditions.

Since there exists a huge amount of audiovisual content in the cultural heritage domain, it is expected that several cultural heritage objects, as well as entities related with them (i.e. people, places, events etc.), have been described using MPEG-7. On the other hand, the dominant standard in the cultural heritage domain is the CIDOC/CRM; consequently, the MPEG-7 descriptions cannot be directly integrated in the cultural heritage digital libraries. +We present in this paper a mapping model and a system that allow the transformation of the MPEG-7 descriptions to CIDOC/CRM descriptions, thus allowing the exploitation of multimedia content annotations in the cultural heritage digital libraries. In addition, the proposed mapping model allows linking MPEG-7 descriptions to CIDOC/CRM descriptions in a Linked Data scenario.Παρουσιάστηκε στο: International Conference on Theory and Practice of Digital Libraries, TPDSpringer VerlagBibliographic citation: A.Angelopoulou, C.

In addition, the captured multimedia content often fails to give the viewer a comprehensive understanding of the event captured in context. We present a model and a mobile system for multimedia event capturing by a one-man-crew. The system supports: (a) the real time capturing of complex multimedia events of different types, (b) the recording of the capturing process and the metadata associated with the events, (c) the visualization of the events and the capturing process, and (d) the learning and preparation of the one-man-crew that will do the multimedia event capturing. +Παρουσιάστηκε στο: n the proceedings of the FTRA MUE 2011 Conference 28-30 JuneIEEEBibliographic citation: A.

In particular, the aim of this paper is to explore the issues surrounding curriculum design for computer courses with a special focus on programming. It has been argued that the utilisation of learning activities that demonstrate specific pedagogic approaches (inquiry-based learning, collaborative learning, cognitive constructivism or activity based) is limited suggesting that teachers are not fully aware of how to apply different pedagogical considerations to their actual practice. This is more apparent in programming courses because of the increased level of abstraction which may cause certain difficulties in teaching and learning. The creation of curricula based on pedagogically-rich teaching and learning activities, and the introduction of Educational Programming Languages (EPLs) designed for teachers to teach students how to develop computer programs, may generate powerful learning opportunities. The main purpose of this paper is to outline the theoretical underpinning of teaching and learning EPLs, and to argue that, to be comprehensive, curriculum design for programming courses must consider important perspectives, each of which leads to specific ways of teaching programming. The paper starts by surveying the current state of computer science curriculum in the participating countries in the context of curriculum design, before looking at learning theories and EPLs that may be used to support informed decisions for pedagogically-driven programming course design. Each decision requires different approaches to teaching programming which are necessary for aligning theory and practice within a viable educational model. The paper concludes by proposing that information and communication technology (ICT) tools may provide a framework to design and structure teaching and learning activities for programming courses.Παρουσιάστηκε στο: hort paper presented at the ALT-C conference, Nottingham, UK, 7-9 SeptembeBibliographic citation: P.

In the recent years XML databases have also acquired industrial importance due to the widespread applicability of XML in the Web. In this paper we present a framework that bridges the heterogeneity gap and creates an interoperable environment where SPARQL queries are used to access XML databases. Our approach assumes that fairly generic mappings between ontology constructs and XML Schema constructs have been automatically derived or manually specified. The mappings are used to automatically translate SPARQL queries to semantically equivalent XQuery queries which are used to access the XML databases. We present the algorithms and the implementation of SPARQL2XQuery framework, which is used for answering SPARQL queries over XML databases.Παρουσιάστηκε στο: In the proceedings of the 20th International Conference on Database and Expert Systems Applications DEXASpringer VerlagBibliographic citation: N.

However, semantic applications may have to access data from diverse sources across the network. Thus, SPARQL queries may have to be submitted and evaluated against existing XML or relational databases, and the results transferred back to be assembled for further processing. In this paper we describe the SPARQL2XQuery framework, which translates the SPARQL queries to semantically equivalent XQuery queries for accessing XML databases from the Semantic Web environment.Παρουσιάστηκε στο: In the Proceedings of the 2nd World Summit on the Knowledge Society, Crete, GreeceSpringer VerlagBibliographic citation: N.

In the case of objects related to culture and history there is a wealth of related information stored in Digital Libraries. CIDOC/CRM is a new, rapidly adopted standard in the field of cultural heritage that provides a very powerful model for encoding cultural heritage knowledge. In this paper we propose that knowledge is extracted and encoded in MPEG-7 multimedia object descriptions in an automatic manner so that the multimedia objects are augmented with very rich metadata descriptions coming from Digital Libraries. We analyze the mapping problem between CIDOC/CRM and MPEG-7 and we present the algorithms and a software system that supports this mapping.Παρουσιάστηκε στο: In the Proceedings of the ACM International Conference on Image and Video Retrieval (CIVR), Niagara Falls, Canada, July 7-9Association for Computing MachineryBibliographic citation: A.Ntousias,N.

In this paper we propose an approach for spatial information retrieval from images using the concept of ontologies and semantic maps. The term of ontology is used in our case to describe spatial domain knowledge to enhance the search capability and image annotation. The objects are represented by their location in semantic maps. We describe a developed prototype system with a database design for ontologies and semantic maps. We demonstrate the automatic image annotation and the visualization of the spatial queries.

However, several applications need semantic support offered by domain ontologies and semantic Web tools like logic-based reasoners. Thus, there is a strong need for interoperability between XML Schema and OWL. This can be achieved if the XML schema constructs are expressed in OWL, where the enrichment with OWL domain ontologies and further semantic processing are possible. After semantic processing, the derived OWL constructs should be converted back to instances of the original schema. We present in this paper XS2OWL, a model and a sys-tem that allow the transformation of XML Schemas to OWL-DL constructs. These constructs can be used to drive the automatic creation of OWL domain ontologies and individuals. The XS2OWL transformation model allows the cor-rect conversion of the derived knowledge from OWL-DL back to XML con-structs valid according to the original XML Schemas, in order to be used trans-parently by the applications that follow XML Schema syntax of the standards.Παρουσιάστηκε στο: In the proceedings of the 6th International Conference on Ontologies, DataBases, and Applications of SemanticsSpringer VerlagBibliographic citation: C.Tsinaraki, S.

Advanced semantic support, provided by domain ontologies and se-mantic Web tools like logic-based reasoners, is still very useful for many appli-cations. In order to provide it, interoperability between XML Schema and OWL is necessary so that XML schemas can be converted to OWL. This way, the semantics of the standards can be enriched with domain knowledge encoded in OWL domain ontologies and further semantic processing may take place. In or-der to achieve interoperability between XML Schema and OWL, we have de-veloped XS2OWL, a model and a system that are presented in this paper and enable the automatic transformation of XML Schemas in OWL-DL. XS2OWL also enables the consistent transformation of the derived knowledge (individu-als) from OWL-DL to XML constructs that obey the original XML Schemas.Παρουσιάστηκε στο: In the proceedings of the 1st DELOS Conference,Springer VerlagBibliographic citation: C.Tsinaraki , S.

The Object Management Group (OMG) defines a four layered modelling architecture, the Model Driven Architecture (MDA), which provides mechanisms for rapid development of modelling languages addressing domain problems using the Meta Object Facility (MOF). MOF incorporates object oriented concepts and is a subset of UML. Furthermore, as users typically don’t know how to make requests, the system has to be tolerant. The Query Metamodel Language (QML) is a language that ex-ploits the Object Constraint Language (OCL) (which is very closely associated with UML and therefore MOF) to provide powerful query support on model repositories. This paper presents the motivation for QML along with its abstract syn-tax. It also introduces the framework for QML processing that incorporates information retrieval functionality and is used to formulate fuzzy queries using the extended boolean model. It describes how QML is integrated in the MOF architecture and how semantic expansion of queries and evaluation can be done in an effective way.Presented on: IEEEBibliographic citation: G.

Most of these measures use WordNet as their central resource and not domain ontologies of a particular context. We propose and evaluate a semantic relatedness measure for OWL domain ontologies that concludes to the semantic ranking of ontological, grammatically-related structures. This procedure is used to disambiguate in a particular domain of context and represent in an ontology query language, natural language expressions. The ontology query language that we use is the SPARQL. The construction of the queries is automated and also dependent on the semantic relatedness measurement of ontology concepts. The methodology has been successfully integrated into the OntoNL Framework, a natural language interface generator for knowledge repositories. The experimentations show a good performance in a number of OWL ontologies. +Παρουσιάστηκε στο: Ιn the Proceedings of the 4th European Semantic Web Conference (ESWC), Innsbruck, Austria, 3-7 JuneSpringer VerlagBibliographic citation: A.

In addition to the syntactic analysis components, +OntoNL has semantic analysis components which exploit +domain ontologies to provide better disambiguation of the +user input. We present in this paper the algorithms used +for semantic processing of the natural language queries, as +well as an ontology-driven semantic relatedness measure +developed for this purpose. We also present extensive evaluation +results with different ontologies using human subjects.Presented on: Bibliographic citation: A. Karanastasi , S.
