Development of methodologies for the deployment and the evaluation of wireless sensor networks using computational geometry algorithms
In recent years, Wireless Sensor Networks and GeoSensor Networks (WSN and GSN) have rapidly evolved and now comprise a powerful tool in monitoring and observation of the natural environment, among other fields. The use of WSNs is critical in early warning systems, which are in high importance today.The optimum deployment of sensors is a multi-dimensional problem, which has two main components; network and positioning approach. In some cases, it is hard or even impossible to achieve perfect geometry in nodes’ deployment. The ideal and desirable scenario of nodes arranged in square or hexagonal grid would raise extremely the cost of the network, especially in unfriendly or hostile environments. In such environments the positions of the sensors have to be chosen among a list of possible points, which in most cases are randomly distributed. This constraint has to be taken under consideration during the WSN planning. Full geographical coverage is in some applications of the same, if not of greater importance than the network coverage. Cost is a crucial factor in network planning and given that resources are often limited, what matters, is to cover the whole area with the minimum number of sensors.In this PhD thesis a new methodology for sensor deployment and evaluation of the geometry of WNS is developed. The proposed methodology can be applied in any application, in which a WSN is required, with or without limitations to the positioning of the sensors, such as a fire detection WSN in a forest area or an extensive network for detecting deformations.The thesis consists of five chapters.The first chapter presents the relatively new science of WSNs and geosensorics. Definitions and basic concepts are given regarding the use of these instruments as a means for detection and monitoring of natural and artificial environment.In the second chapter the optimal deployment problem of a WSN is described. An introduction to the computational geometry and its application fields is made. The solution is approached by using the properties of Voronoi Diagrams and more specifically, the Centroidal Voronoi Tessellation (CVT). The theoretical background for both VD and CVT is given, before the proposed methodology is thoroughly explained.In the third chapter the evaluation method of the deployment of a WSN is approached, using the Delaunay triangulation, which is the dual graph of the Voronoi diagram.The fourth chapter presents the software created for the proposed deployment and evaluation methodologies of a WSN.In order to examine the functioning and the efficiency of the algorithm, different simulation scenarios were created and tests with different parameters were conducted. Special occasions of deployment are also faced. The findings of all these scenarios are recorded and analyzed.In the fifth and final chapter the conclusions of the research are presented and recommendations for future work are made.The main conclusion of the thesis is that the specific deployment and evaluation methodologies for WSNs and GSNs in any environment is efficient, fully customizable and reliable.With criterion the minimizing of the cost of the installation and the maintenance of the network, the optimum positions among all the candidate ones are searched, in order to achieve full coverage of the area with geometry that is as close as possible to the ideal one (equilateral triangles).Τα τελευταία χρόνια, τα ασύρματα δίκτυα αισθητήρων και γεωαισθητήρων (WSN και GSN) εξελίσσονται με γρήγορο ρυθμό και συνθέτουν ένα ισχυρό εργαλείο για την παρακολούθηση και την παρατήρηση του φυσικού περιβάλλοντος.

Homophobic Statements, a Bishop, and the Limits of Freedom of Expression. An In-Depth Commentary on ECtHR 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20
Dichiarazioni omofobe, un vescovo e i limiti della libertà di espressione. Un commento approfondito su CEDU 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20.
ABSTRACT: The decision of the ECtHR of 31.08.2023, Amvrosios-Athanasios Lenis v. Greece (no. 47833/20), is a further step toward an increasingly dense jurisprudence on “hate speech” and the limits of freedom of expression. The public proclamation of religious doctrines that are in conflict with the values of the contracting States enshrined in the ECHR is protected to a certain extent by the fundamental right of freedom of religion and belief. However, the qualification of a statement as religious does not justify “hate speech.” The AUTHOR shows the tension between freedom of religion, freedom of expression, and protection against discrimination, and analyzes the decision against the backdrop of Article 17 of the ECHR (prohibition of abuse of rights).

The Procedure and Reasoning of the Court - 4.1 The ECtHR’s Preliminary Considerations on Fundamental Rights - 4.2 Legal assessment - 4.3 Some Remarks on (the Non-Invoked) Article 9 of the ECHR - 5.

La tomba III di Haghios Athanasios e il valore semantico dell'incarnato
The tomb III at Haghios Athanasios stands out among the Macedonian tombs for the exceptional painted decoration of the temple-like façade. Excavated in the '90s by M. Tsimbidou-Avloniti it has been published by the scholar in full detail and the iconographic program of the monument has been the object of many publications. This article re-examines the different ways of reproducing the skin color (το ανδρείκελον) in the figures of the miniature frieze and in the megalographic figures beside the door. The realistic rendering of the megalographic figures of armed men in Macedonian attire, showing their sorrow for the lost of an etairos, is contrasting with the pale color of the participants to the symposion in the frieze above the door, a scene whose illusionistic overtone has been yet perceived by the critics. This symposion is articulated in three scenes and it can be interpeted as a necrodeipnon, but in the same time as a celebration of the Macedonian banquet style, centered on the royal court. The author suggests that the first figure on the right of the frieze, related to the group of armed men looking towards the banqueters feasting in the center of the frieze, can be read as the dead himself, for the particular rendering of his ανδρείκελον, showing the typical ochròtes or necròdes face color, according to the contemporary medical lexicon. The pathetic stance assumed by the same figure, the sole in the group which is not bearing arms, seems to confirm his role in the context of the scene

Historical elements with regard to the development of total stations, as well as the characteristics of the distance measurement using laser radiation are given. The chapter is focused in both used methods for the distance measurement by the total stations. The methods are compared. A brand new method that combines the advantages of the two previous methods is described. The chapter ends with a detailed list of the today widely used total stations including their characteristics. In the second chapter some of the classical methods for the points’ coordinates determination are described. Methods for the height determination (3rd dimension) and for 2D and 3D determination are referred. The precision of each one and the factors that affect them are also analyzed. Extensive analysis of the method of the Accurate Trigonometric Heighting (ATH) for the determination of the height differences between accessible or/and inaccessible points is attained. The precision of the intersection method is also analyzed. The third chapter presents the use of the method of ATH for the vertical control network of the Karaiskaki Stadium. The network is measured and adjusted. The heights of the control points are calculated. The results are evaluated in reference to the precision succeeded and the time needed. Comparisons between specific height differences that had been measured using spirit levelling in a previous work is carried out. The fourth chapter deals with the process of the measurement of a crane. The method of polar coordinates is used. The aim of the present application is the investigation of the precision could achieved using the polar coordinates’ method (instead of the intersection method that is traditionally used in similar applications) and its appropriateness for the control of the safety specifications of the crane. In the fifth chapter the process for the determination of the position of the inaccessible points of an electric power transportation cable is developed. The process of the geometric documentation of the cable and the investigation of the best polynomial fitting curve are analyzed. Finally, in the last chapter (6th) the conclusions and the proposals that were came out by this work are presented.Αθανάσιος Ε. Ηλιοδρομίτη
Computational Modelling of Compaction in Asphaltic Mixtures and Geomaterials
Asphaltic mixtures are heterogeneous composite materials consisting of aggregates coated and bound by asphalt binder. The long term performance of asphaltic pavements is highly dependent on the mechanical behaviour of the asphaltic mixture during construction (mixing and compaction) and operation; inadequate mixture compaction leads to faster moisture and oxygen diffusion, ravelling, rutting and poor fatigue life
Moisture damage susceptibility of asphalt mixtures: Experimental characterization and modelling
A well-functioning, long-lasting and safe highway infrastructure network ensures the mobility of people and facilitates the transport of goods, promoting thus environmental, economic, and social sustainability. The development of sustainable highway infrastructure requires, among other activities, the construction of pavement systems with enhanced durability. Moisture damage in asphalt pavements is associated with inferior performance, unexpected failures and reduced service life. All of these contribute to the increase of operational and maintenance costs in order to fulfill the intended service life of the pavement system. Moreover, global warming and climate change events such as temperature extremes, high mean precipitation and rainfall intensity may further increase the probability and rate of pavement deterioration. This dissertation aims to obtain an advanced understanding of the influence of moisture on pavement durability by developing a set of tools, i.e. experimental methods and computational models, which will provide insight into the fundamental moisture damage processes and on their impact on pavement systems. Based on this knowledge, researchers and practitioners will be able not only to design pavements with increased resiliency, thereby providing reliable services to road users, but also to minimize the risks in the face of changing climate conditions.Moisture diffusion is well-known to degrade the mechanical properties of asphalt mortars, namely bitumen, filler and sand, thus increasing the propensity of pavements to cracking. To determine the changes in the cohesion properties of the mortar, uniaxial tension tests were performed. Mortar samples were prepared and then subjected to five combinations of moisture and thermal conditioning, in an attempt to reproduce the various conditioning states that pavements undergo in the field, before being tested. Tensile strength and fracture energy were used to evaluate the changes in mechanical properties due to the various conditioning protocols. To post-process the experimental data, a new data analysis procedure was suggested in order to obtain a more accurate calculation of fracture energy. The procedure uses nonlinear finite element analysis to specify the unloading response outside the fracture zone, and then utilizes this information to compute the fracture energy of the binders. This methodology yields a framework for the calculation of fracture energy when only force-displacement data are available and therefore the estimation of the true stress-strain curve is not feasible.The experimental investigation revealed the deteriorating impact of moisture on the fracture characteristics of asphalt mortars, especially as regards to their low temperature properties. These effects were not reversible upon drying. On the contrary, the application of a drying cycle caused embrittlement of the mortars and indicated that continuous wet and drying cycles in the field may result in materials with poor performance characteristics. Also, the application of freeze-thaw cycles was shown to increase the susceptibility of mortars to low temperature cracking. Nevertheless, on the whole, the effect of freeze-thaw on fracture properties was observed to depend on the conditioning state (dry or wet) and composition of the mortars. The use of additives, such as hydrated lime filler and SBS modifiers, were found to improve the wet strength and fracture energy of the mortars. On the basis of moisture uptake measurements, it was confirmed that the chemical composition influences significantly the diffusivity characteristics of the mortars. Also, the maximum moisture uptake was found to be the main parameter that dictates the intensity of mortar damage. In addition, moisture susceptibility was studied at mixture level. At this level, besides moisture diffusion, excess pore pressure can contribute to the degradation of mixture performance depending on the mixture type, the traffic loading and the environmental conditions. Hence, a moisture conditioning protocol that comprises two conditioning types, namely bath immersion and pore pressure application, was proposed for evaluating susceptibility of asphalt mixtures to moisture. Also, evidence was collected of the effect that dynamic pore pressure has on mixture degradation by means of X-ray computed tomography and image analysis techniques. The two damage mechanisms were found to be relatively independent from each other, suggesting that an asphalt mixture can be more prone to one damage mode than the other, depending on its composition. The proposed protocol captures both processes that occur when water interacts with a pavement and can provide more reliable conclusions with regard to mixture sensitivity.In order to improve our perception of the influence of material microstructures on moisture sensitivity of the asphalt composite, an energy-based elasto-visco-plastic model with softening was implemented to model damage due to the coupled effects of moisture diffusion and mechanical loading. The model consists of a generalized Maxwell model, with hyperelastic springs and viscous time-dependent components, in series with an inelastic component that accounts for the irreversible processes within the microstructure of the material. Then, a computational scheme was proposed by means of a staggered approach: first a three-dimensional diffusion model was applied to obtain information on the accumulation of moisture within the mixtures and then the elasto-visco-plastic model was used to quantify mortar damage due to moisture diffusion. This method was successfully applied to study the influence of mixture morphology on moisture sensitivity. The results demonstrated that moisture content in a mixture strongly depends on its morphology, whereas the interconnectivity of the voids network controls the rate of damage development. Also, the analysis revealed the positive effect of using binders with high resistivity against moisture and quantified the benefits that would arise due to this choice, especially when designing porous mixtures that have an intrinsic sensitivity to moisture due to their morphological characteristics.More broadly, frost damage can be classified as part of the moisture damage related mechanisms. In the field, frost damage can be mainly attributed to the expansion of water accumulated in the pores of the pavement at sub-zero temperatures that causes additional stresses to the pavement structure. A numerical scheme to simulate frost damage was proposed. This scheme comprises a model that simulates the volume expansion of water during the water-to-ice phase-change, a thermal conduction model to simulate temperature distribution in the pavement, and the elasto-visco-plastic model to determine critical areas with a propensity to cracking on the basis of the pavement stresses.In conclusion, this thesis contributes to establishing a relationship of the physico-mechanical properties of the constituent materials and mixture morphology with the moisture susceptibility of pavement structures. The proposed experimental methods and computational models can serve as tools to investigate a great variety of parameters before a pavement structure is actually built. This allows for new materials and mixture designs to be investigated and the risks involved with their use to be minimized.<br/
