description: Product Line Engineering (PLE) has attracted attention in the last two decades due to its promising capabilities to reduce system life-cycle costs and time to market through the reuse of requirements and components. Current PLE methods, however, mainly focus on the software aspects and are called Software Product Line Engineering (SPLE). While SPLE is important in the systems domain, Systems Engineering is a much broader discipline; it includes the consideration of hardware aspects (mechanical and electrical engineering) as well as the overall integration of hardware and software components.This thesis proposes a novel and practical method to support a development of Model-based Product Line Engineering (MBPLE) for Embedded Real-Time Systems (RTS) for both Domain Engineering and Application Engineering processes. It consists of four main contributions: (i) a variability modelling framework that provides capability to capture variabilities with Systems Engineering disciplines. (ii) a Domain Engineering framework to combine proposed variability model (introduced in (i)) with system models to build system reusable artefacts. (iii) a Product Line Systems Engineering Process that consumes legacy system models to semi-automate the generation of variability model and variability dependency (achieved through formalising dependencies existed in the variability model, the functional artefacts and between the two); and reduces configuration efforts of variability model by a proposed algorithm (grounded in formal notation and mathematical framework, which promises trustworthiness and verifiability of the reduced variability model). (iv) an approach that extends the UML profile for ROSETTA (UPR) for proposed variability framework to facilitate trade-off analysis during Application Engineering process for target system generation.To verify the feasibility and evaluate the effectiveness of the proposed MBPLE for Embedded RTS, it is further applied to case studies in different engineering domains including Engine Control Systems, Aircraft Systems, Logistics Systems, Automotive Systems and Remote Health Monitoring Systems at different levels of complexity. Subjected to system model availability, a reduction of 14%–50% in the number of variation points is demonstrated in the case studies.

Η βιβλιογραφική ανασκόπηση του ζητήματος παρουσιάζεται εκτενώς μαζί με ένα εννοιολογικό πλαίσιο της προσωπικότητας της μάρκας, του Word of Mouth και Revisit Intention. Η συλλογή των δεδομένων και πληροφοριών πραγματοποιήθηκε μέσω ερωτηματολογίου σε μέγεθος δείγματος 95 ατόμων – πελατών του καταλύματος. Με βάση αυτά τα δεδομένα πραγματοποιήθηκε ανάλυση παραγόντων των διαστάσεων του Brand Personality, καθώς και ανάλυση απλής γραμμικής παλινδρόμησης, προκειμένου να διαπιστωθεί η επίδραση του Brand Personality στην πρόθεση διάδοσης του Word of Mouth και της επανάληψης της επίσκεψης (Revisit Intention). Τα αποτελέσματα της έρευνας φανερώνουν πως παρ’ όλο που υπήρξε μονοδιάστατη προσωπικότητα της μάρκας, οι 5 διαστάσεις του Brand Personality επιδρούν σημαντικά στο Word of Mouth και τα Revisit Intentions.
description: The purpose of this study is to investigate the influence of Brand Personality of the tourist accommodation “La Sirenetta Apartments” in Sivota of Thesprotia on the intention of tourists to spread a positive Word of Mouth, but also on their intention to visit the accommodation again in the future. The literature review of the issue is presented extensively along with a conceptual framework of Brand Personality, Word of Mouth and Revisit Intention. The collection of data and information was carried out through a questionnaire in a sample size of 95 people - customers of the accommodation. Based on these data, a factor analysis of Brand Personality dimensions was performed, as well as a simple linear regression analysis, in order to determine the effect of Brand Personality on the intention to spread the Word of Mouth and Revisit Intention. The results of the research show that although there was a one-dimension Brand Personality, the 5 dimensions of Brand Personality have a significant impact on Word of Mouth and Revisit Intentions.

description: We study the profile $X_{n,k}$ of random search trees including binary search trees and $m$-ary search trees. Our main result is a functional limit theorem of the normalized profile $X_{n,k}/\mathbb{E}X_{n,k}$ for $k=\lfloorα\log n\rfloor$ in a certain range of $α$. A central feature of the proof is the use of the contraction method to prove convergence in distribution of certain random analytic functions in a complex domain. This is based on a general theorem concerning the contraction method for random variables in an infinite-dimensional Hilbert space. As part of the proof, we show that the Zolotarev metric is complete for a Hilbert space.

Legacy Survey of Space and Time

description: The Vera C. Rubin Observatory’s Legacy Survey of Space & Time (LSST) will be a 10-year optical and near infrared survey of the southern sky, expected to start operations in mid 2025. Exploring the transient optical sky is a key LSST science driver; LSST will issue 1 million alerts from transient, variable, and moving sources via a world-public alert stream. Seven full-stream “community brokers” are preparing to receive the LSST alert stream, add value and redistribute it to the scientific community. In this talk I will review the time-domain infrastructure for exploiting the LSST data and enabling follow up observations. I will also discuss Rubin’s plans for a Target of Opportunity (ToO) program and plans for processing of ToO data in early operations
Stress response of porphyromonas gingivalis

description: The heat shock response of Porphyromonas gingivalis was examined by one-and two-dimensional polyacrylamide gel electrophoresis after metabolic labeling with (14C)-amino acids. When P. gingivalis cells were shifted from 37°C to 42°C, elevated synthesis of four proteins with the apparent molecular weight of 92, 80, 74, and 62kDa was observed, whereas synthesis of a 50kDa protein decreased during heat shock. The 74 and 62kDa proteins were identified as homologs of E. coli DnaK and GroEL respectively by Western immunoblotting. On two-dimensional Western blots, two forms of DnaK and four forms of GroEL were identified due to their slightly different isoelectric points. dnaK and groEL gene homologs were identified in several P. gingivalis and some other black-pigmented Bacteroides strains by Southern hybridization. DnaK and GroEL homolog proteins and some other proteins were also induced when P. gingivalis cells were challenged by ethanol. Exposure to oxidative stress and an elevation or decrease in pH did not show a discernible induction of these heat shock proteins. GroEL and DnaK homolog proteins were not induced in P. gingivalis cells recovered from a guinea-pig infection model.

Stochastic resonance was first introduced as a possible mechanism to explain long term climatic variation. Since then, there have been many applications of stochastic resonance in physical and biological systems. I will show that in complex system, stochastic resonance can substantially change as a function of the ``system complexity''. Also, I will briefly mention how to apply stochastic resonance for the case of Brownian motors.

description: The generalized Lin-Taylor model defined on the hexagonal lattice is used to investigate the phase separation in an asymmetric binary liquid mixture consisting of large A (hexagons) and small B (triangles) particles. By considering interaction energies between A-A and A-B pairs of particles that occupy nearest-neighbour cells of the hexagonal lattice, we have derived an exact solution for the considered model system having established a mapping correspondence with the two-dimensional Ising model on its dual triangular lattice. Altogether, six different types of coexistence curves including those with reentrant miscibility regions (i.e. closed-loop coexistence curves) were found in dependence on the relative strength between both coupling constants.

description: This paper presents (Lagrangian) variational formulations for single and multicomponent semi-compressible fluids with both reversible (entropy-conserving) and irreversible (entropy-generating) processes. Semi-compressible fluids are useful in describing \textit{low-Mach} dynamics, since they are \textit{soundproof}. These models find wide use in many areas of fluid dynamics, including both geophysical and astrophysical fluid dynamics. Specifically, the Boussinesq, anelastic and pseudoincompressible equations are developed through a unified treatment valid for arbitrary Riemannian manifolds, thermodynamic potentials and geopotentials. By design, these formulations obey the 1st and 2nd laws of thermodynamics, ensuring their thermodynamic consistency. This general approach extends and unifies existing work, and helps clarify the thermodynamics of semi-compressible fluids. To further this goal, evolution equations are presented for a wide range of thermodynamic variables: entropy density $s$, specific entropy $η$, buoyancy $b$, temperature $T$, potential temperature $θ$ and a generic entropic variable $χ$; along with a general definition of buoyancy valid for all three semicompressible models and arbitrary geopotentials. Finally, the elliptic equation is developed for all three equation sets in the case of reversible dynamics, and for the Boussinesq/anelastic equations in the case of irreversible dynamics; and some discussion is given of the difficulty in formulating the elliptic equation for the pseudoincompressible equations with irreversible dynamics.

description: A dilute suspension of motile microorganisms subjected to a strong ambient flow, such as algae in the ocean, can be modelled as a population of non-interacting, orientable active Brownian particles (ABPs). Using the Smoluchowski equation (i.e. Fokker-Planck equation in space and orientation), one can describe the non-trivial transport phenomena of ABPs such as taxis and shear-induced migration. This work transforms the Smoluchowski equation into a transport equation, in which the drifts and dispersions can be further approximated as a function of the local flow field. The new model can be applied to any global flow field due to its local nature, unlike previous methods such as those utilising the generalised Taylor dispersion theory. The transformation shows that the overall drift includes both the biased motility of individual particles in the presence of taxis and the shear-induced migration in the absence of taxis. In addition, it uncovers other new drifts and dispersions caused by the interactions between the orientational dynamics and the passive advection-diffusion of ABPs. Finally, the performance of this model is assessed using examples of gyrotactic suspensions, where the proposed model is demonstrated to be most accurate when the biased motility of particles (i.e. taxis) is weak.

H2 ro-vibrational excitation in protoplanetary disks and its effects on the chemistry

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The effect of H$_2$ ro-vibrational excitation on the chemistry of protoplanetary disks is studied using a framework that solves for the disk physical and chemical structure and includes a detailed calculation of H$_2$ level populations. Chemistry with ro-vibrationally excited H$_2$ is found to be important for the formation of several commonly observed species in disks and this work demonstrates the need to accurately treat PDR chemistry in disks if we are to make inferences on the chemical state of the disk during planet formation epochs. This is found to be even more critical for molecules like C$_2$H, CN or HCN that are commonly used to infer changes in the elemental disk C/O and N/O ratios, with implications for planetesimal formation and the composition of exoplanet atmospheres. Computed vertical column densities with the full H$_2$ population calculation are increased by $\sim1-2$ orders of magnitude for molecules such as CN, HCN/HNC compared to calculations with no treatment of excited H$_2$. For the commonly used pseudo-level approximation, the computed columns of these molecules are overestimated by a factor of $\sim3-5$ when compared to the full model. We further note that the computed abundance for these molecules strongly depends on the strength of the FUV photons at energies that pump H$_2$ (i.e. 11-13.6 eV), which is not well constrained in disks, and that rate constants as a function of H$_2$ ro-vibrational levels for the key reaction N + H$_2\rightarrow $ NH are needed for a more accurate assessment of CN/HCN chemistry but are currently unavailable.

description: The growing challenges of modern global ecological crisis render the study of urban landscapes necessary to address these challenges, to improve the environmental quality in the context of sustainability as well as to strengthen the identity of landscapes and people living in them, something that is broadly recognized in the European Landscape Convention. The Education for the Environment and Sustainability may contribute to the information and awareness raising of individuals and institutions for their activation in planning and management of urban landscape with the goal of sustainable fuction of modern cities. As case study, in the investigation of questions concerning the evolution of landscapes over space and time and the role of human activities, has been chosen the 4th Munipality of Thessaloniki, namely the region of Toumpa, as it is a region of particular cultural and environmental interest.

description: Astrometric precision and knowledge of the point spread function are key ingredients for a wide range of astrophysical studies including time-delay cosmography in which strongly lensed quasar systems are used to determine the Hubble constant and other cosmological parameters. Astrometric uncertainty on the positions of the multiply-imaged point sources contributes to the overall uncertainty in inferred distances and therefore the Hubble constant. Similarly, knowledge of the wings of the points spread function (PSF) is necessary to disentangle light from the background sources and the foreground deflector. We analyze adaptive optics (AO) images of the strong lens system J0659+1629 obtained with the W. M. Keck Observatory using the laser guide star AO system. We show that by using a reconstructed point spread function we can i) obtain astrometric precision of $< 1$ milliarcsecond (mas), which is more than sufficient for time-delay cosmography; and ii) subtract all point-like images resulting in residuals consistent with the noise level. The method we have developed is not limited to strong lensing, and is generally applicable to a wide range of scientific cases that have multiple point sources nearby.

description: Non-Hermitian skin effect exhibits the collapse of the extended bulk modes into the extensive number of localized boundary states in open boundary conditions. Here we demonstrate the disorder-driven phase transition of the trivial non-Hermitian system to the higher-order non-Hermitian skin effect phase. In contrast to the clean systems, the disorder-induced boundary modes form an arc in the complex energy plane, which is the manifestation of the disorder-driven dynamical phase transition. At the phase transition, the localized corner modes and bulk modes characterized by trivial Hamiltonian coexist within the single-band but are separated in the complex energy plane. This behavior is analogous to the mobility edge phenomena in the disordered Hermitian systems. Using effective medium theory and numerical diagonalizations, we provide a systematic characterization of the disorder-driven phase transitions.

description: The subject of my thesis is the satire against women in the Cretan and the Heptanese comedies. My focus is to study the satirical comments in these works, from male or female characters, against women. In the case of Cretan drama, I will approach this subject throughout the three extant comedies: Katzourbos by Georgios Chortatsis, Fortounatos by Markos-Antonios Foskolos and Stathis, from an anonymous writer. In the Heptanese drama on the other hand, I examine the three conclusive comic scenes of the tragedy Ifigeneia by Petros Katsaitis, the comic plays by Savogias Rousmelis: the Intermezzo of Lady-Olive (Ιντερμέδιο της κυρα-Λιάς) and the Comedy of Pseudo-Doctors (Κωμωδία των Ψευγογιατρών), and the comedy Chasis by Dimitrios Gouzelis. In my thesis, I will not confine this study in a simple exposition-description of those satiric comments, but I will take a close look into the functionality of the comic impact on those works, and then move on to the examination of interlocutory correlations between the plays as to the anti-women satire.

Πράγματι, υπό το φως μίας σειρά τεχνολογικών και κοινωνικών παραγόντων που καθιστούσαν επιβεβλημένη τη συγκεκριμένη εξέλιξη, ο νόμος αυτός δημιούργησε ένα ολοκληρωμένο σύστημα συλλογικής προστασίας, διαφορετικό κατά τη φύση και τα αποτελέσματά του από την κλασική ατομοκεντρική προστασία. Από την άλλη πλευρά, οι ΗΠΑ θεωρούνται η πατρίδα της class action. Μέσω αυτής, η δίκη διεξάγεται από ένα ή περισσότερα άτομα, τα οποία θεωρούνται αντιπρόσωποι της ομάδας, χωρίς να καθίσταται αναγκαία η συμμετοχή του συνόλου των μελών της ομάδας στη δίκη. Στο πλαίσιο της παρούσας, ξεκινάμε περιγράφοντας τη διαδικασία της συλλογικής αγωγής και της class action αντίστοιχα, εμμένοντας ιδίως σε ζητήματα σχετικά με τα νομιμοποιούμενα υποκείμενά τους. Στη συνέχεια, εντοπίζουμε τα νόμιμα αιτήματα των δύο, δίνοντας έμφαση στο ζήτημα της κυρωτικής αποζημίωσης. Τέλος, εξετάζουμε τη δεσμευτικότητα των αποφάσεων που εκδίδονται επί συλλογικής αγωγής και class action, παρακολουθώντας ιδίως τις διαφορετικές προσεγγίσεις μεταξύ των θεωρητικών του δικαίου αλλά και της νομολογίας σε σχέση με τη συλλογική αγωγή.
description: Law No 2251/94 added a novel legal remedy, namely the class action, alongside the standard individual protection offered by civil law. Indeed, under numerous technological and social factors, this development appeared as necessary. The aforementioned law introduced a fully fledged system of collective protection, different by its nature and results from the standard individualist protection. On the other hand, class action is considered to have been born in the USA. In this framework, the trial is conducted by one or more persons, considered to be the representatives of the relevant group. The participation of the remaining members of the group is non-obligatory. In this thesis, we begin by describing both processes, putting emphasis on who qualifies to conduct such a trial. Next we examine the lawful requests in both procedures, stressing the issue of punitive damages. We conclude by exploring the binding effect of the relevant decisions, emphasizing the discrepancy between theory and case law in relation to collective action.

description: Fluid retention is associated with congestive heart failure (CHF). The role played by atrial natriuretic factor (ANF), brain natriuretic peptide (BNP), C-type natriuretic peptide (CNP) and arginine vasopressin (AVP) in CHF is not fully understood. Studies were done in 300days old male normal and cardiomyopathic hamsters with moderate CHF. Their body and heart weights were measured. Blood was collected for ANF measurement. Urine was collected for cAMP, cGMP and creatinine measurement. In vitro cGMP accumulation studies were done in inner medullary duct cells (IMCD) cells upon stimulation by ANF, and in glomeruli upon stimulation by ANF, BNP and CNP. cAMP accumulation studies were done in IMCD cells upon addition of AVP and forskolin. ANF, BNP and CNP radioligand studies were performed in glomerular membrane. Results showed that baseline cGMP/creatinine ratios and the plasma ANF levels were higher in the cardiomyopathic hamsters. The plasma ANF levels correlated with the total heart weight/body weight ratios of the diseased hamsters. The urinary cGMP/creatinine ratios also correlated with the plasma ANF levels. ANF-stimulated cGMP accumulation in glomeruli and IMCD cells of cardiomyopathic hamsters were higher than normal animals. Greater accumulation of cGMP also occurred in cardiomyopathic hamster glomeruli after BNP addition. No increase in cGMP was observed in glomeruli stimulated by CNP in both groups. AVP- and forskolin-stimulated cAMP accumulations in IMCD cells were higher in cardiomyopathic animals. ANF radioligand studies showed that the affinities of the high affinity receptor were similar between the two groups, but the affinity of the low affinity receptors was reduced in cardiomyopathic hamsters. The density of high and low affinity ANF receptors were both increased in cardiomyopathic hamsters. The affinity of BNP high affinity receptor increased significantly. Other changes of BNP receptor properties were similar to that of ANF. CNP radioligand experiments showed no CNP binding in hamster glomeruli. In conclusion, there is activation of the natriuretic peptide system at the hormonal, receptor and second messenger levels in CHF. It is likely that AVP hypersensitivity rather than natriuretic peptide hyposensitivity in kidney is the possible underlying mechanism of fluid retention in CHF.

description: Two-dimensional election gases (2DEG), arising due to quantum confinement at interfaces between transparent conducting oxides, have received tremendous attention in view of electronic applications. The challenge is to find a material system that exhibits both a high charge-carrier density and mobility, at and even above room temperature. Here, we explore the potential of interfaces formed by two lattice-matched wide-gap oxides of emerging interest, $\textit{i.e.}$, the polar, orthorhombic perovskite LaInO$_{3}$ and the non-polar, cubic perovskite BaSnO$_{3}$, employing density-functional theory and many-body theory. We demonstrate that this material combination exhibits all the key features for reaching the goal. For periodic heterostructures, we find that the polar discontinuity at the interface is mainly compensated by electronic relaxation through charge transfer from the LaInO$_{3}$ to the BaSnO$_{3}$ side. This leads to the formation of a 2DEG hosted by the highly-dispersive Sn-$s$-derived conduction band and a 2D hole gas of O-$p$ character, strongly localized inside LaInO$_{3}$. Remarkably, structural distortions through octahedra tilts induce a depolarization field counteracting the polar discontinuity, and thus increasing the $critical$ (minimal) LaInO$_{3}$ thickness, $t_c$, required for the formation of a 2DEG. These polar distortions decrease with increasing LaInO$_{3}$ thickness, enhancing the polar discontinuity and leading to a 2DEG density of 0.5 electron per unit-cell surface. Interestingly, in non-periodic heterostructures, these distortions lead to a decrease of $t_c$, thereby enhancing and delocalizing the 2DEG. We rationalize how polar distortions, termination, and thickness can be exploited in view of tailoring the 2DEG characteristics, and why this material is superior to the most studied prototype LaAlO$_{3}$/SrTiO$_{3}$.

description: Ο σκοπός αυτής της εργασίας ήταν η ανάπτυξη ενός συστήματος απόδοσης της σωματικής και πνευματικής άσκησης σε τρισδιάστατα μοντέλα τα οποία θα χρησιμοποιούνταν για την τρισδιάστατη εκτύπωση ψηλαφητών ανταμοιβών για τις ασκήσεις από τις οποίες προήλθαν. Η εμπορική συσκευή ηλεκτροεγκεφαλογραφήματος (ΗΕΓ) Muse χρησιμοποιήθηκε για την καταγραφή σήματος στα κανάλια TP9, TP10, AF7, και AF8 διαρκείας 5 λεπτών. Η εμπορική συσκευή έξυπνου ρολογιού Vivosmart HR+ της εταιρίας Garmin χρησιμοποιήθηκε για τη λήψη του καρδιακού ρυθμού πριν την έναρξη και αμέσως μετά τη λήψη της καταγραφής. Ο καρδιακός ρυθμός κατά τη διάρκεια της καταγραφής προσεγγίστηκε με την καταμέτρηση των διαστημάτων RR, χάρη στη παρουσία της συνιστώσας του ηλεκτροκαρδιογραφήματος στο ΗΕΓ. Η ένταση της πνευματικής ενσυνείδησης εξήχθη από την ζώνη α του ΗΕΓ ενώ η ένταση της φυσικής άσκησης εξήχθη από τον καρδιακό ρυθμό. Το σύστημα που υλοποιήθηκε χρησιμοποίησε κάθε ζεύγος μετρήσεων σωματικής/ενσυνείδητης άσκησης για τον σχεδιασμό ενός τρισδιάστατου μοντέλου το οποίο στη συνέχεια τροφοδοτήθηκε στον τρισδιάστατο εκτυπωτή Finder της εταιρίας Flashforge. Τα φυσικά μοντέλα που προέκυψαν από τη διαδικασία της εκτύπωσης δόθηκαν στον χρήστη από τον οποίο προέκυψε η καταγραφή με τη μορφή ανταμοιβής. Με αυτόν τον τρόπο ο κάθε χρήστης έχει τη δυνατότητα να αναλογιστεί και να εσωτερικεύσει καλύτερα την έκταση της προσπάθειας και της αποτελεσματικότητας της άσκησής του.
description: The purpose of this work was to develop a system to demonstrate physical and mental activity data in a 3D model which would be used to 3D print tangible rewards for the exercises from which they were generated from. The proprietary electroencephalography (EEG) device Muse was used to record signal from the TP9, TP10, AF7, and AF8 leads for 5 minutes. The proprietary smartwatch Vivosmart HR+ from the company Garmin was used to log the heart rate right before and after the EEG recording. The heart rate during the recording was approximated by measuring the RR intervals, thanks to the electrocardiogram’s contribution to the EEG signal. The meditation state was extracted from the Alpha frequency band of the EEG while the physical activity intensity was inferred from the heart rate. The implemented system used every pair of physical/mental measurements to generate a 3D model which in turn was used by the 3D printer Finder from the Flashforge company. The printed physical tokens were then given to their corresponding users as a reward. As such each user had the opportunity to reflect and internalize better the extent of their effort and the effectiveness of their exercises.

description: A requirement in the design and operation of gas turbines is to control the metal temperature of the combustor. One method by which this can be achieved is by passing compressor delivery air through arrays of cylindrical, angled effusion holes located in the combustor walls. However, recent advances in additive manufacturing technology have presented the opportunity to develop intricate effusion geometries that offer potential improvements in cooling performance compared to the current state-of-the-art. Much progress has been made in the development of experimental techniques to measure external heat transfer coefficients, film cooling effectiveness and overall cooling effectiveness in these complex effusion cooled walls. However, spatially resolved measurements of the internal convective heat transfer coefficient (HTC) are also required to fully explore the new design space. The research presented in this thesis has developed the capability to quantify these internal HTC distributions from transient convective heat transfer experiments at combustor-scaled near-atmospheric conditions employing thermochromic liquid crystals (TLCs) and 3D infrared (IR) thermography. The transient TLC technique has been improved by using a state-of-the-art imaging system and a new post-processingmethodology. These, along with fundamental research on the optical and ageing effects of multiple TLC films, have allowed to reduce and more accurately quantify the true measurement uncertainty of internal HTC distributions. For test specimens in which internal optical access is limited or not possible, such as for the study of surface roughness effects, a hybrid inverse-conduction technique comprising 3D IR thermography and transient heat transfer simulations has been developed to quantify internal HTCs. This technique is expected to play an important role in the design and development of low-cost additive-manufactured combustors for future aero-engines.

description: Το τοπίο αποτελεί το χώρο όπου αποτυπώνεται η εμπλοκή του ανθρώπου με τον κόσμο. Η σχέση μεταξύ ανθρώπου και τοπίου είναι διαλεκτική, καθώς οι άνθρωποι διαμορφώνουν το χώρο γύρω τους σύμφωνα με τις ανάγκες τους, ενώ ταυτόχρονα προσαρμόζουν τις τελευταίες σύμφωνα με τη διαμόρφωση του τοπίου. Στόχος της παρούσας έρευνας είναι η εξέταση τόσο της προσαρμογής όσο και της παρέμβασης του ανθρώπου στο περιβάλλον, μέσω της περίπτωσης της Πιερίας. Το βασικό μεθοδολογικό εργαλείο της μελέτης αυτής είναι τα Γεωγραφικά Συστήματα Πληροφοριών (GIS). Μέσω της εφαρμογής αυτής της μεθοδολογίας γίνεται προσπάθεια να ανιχνευθούν τα κριτήρια επιλογής των θέσεων, τόσο για οικιστική όσο και για ταφική χρήση. Επιπλέον, εξετάζεται η επικοινωνία μεταξύ των θέσεων σε διακοινοτικό επίπεδο, αλλά και η επικοινωνία (μετακίνηση και ορατότητα) του οικιστικού με τον ταφικό χώρο και αντίστροφα. Σκοπός της εφαρμογής των παραπάνω αναλύσεων είναι η κατανόηση των κοινωνικών αλλαγών όπως αυτές διαμορφώθηκαν στην περιοχή της Πιερίας διαχρονικά κατά την Εποχή του Χαλκού και σε συνάρτηση με το τοπίο.
description: Landscape is where the human involvement in the world is embodied. The relation between human and landscape is interactive, as people form the space around them according to their needs and simultaneously adapt them to the landscape configuration. This paper aims to investigate not only the adaptive, but also the interfering human behavior to the landscape, through the case study from central Macedonia, Greece, via the methodological tool of the Geographical Information Systems (GIS). By this application, the selection of the place for both settlement activity and mortuary practices are analyzed. Moreover, the aforementioned analysis focus on the aspects of the mobility in intercommunity level, but also on the correlation (mobility and visibility) between residential areas and burial sites. Therefore, the main goal of this kind of study is the understanding of the cultural development and changes throughout all the Bronze Age sub phases in central Macedonia in relation to the landscape.

description: This paper addresses the transition of the Self- Sovereign Identity (SSI) model to Post-Quantum Cryptography (PQC) and its practical implementation in the IOTA Identity library. The design and the implementation provide pure Post-Quantum (PQ) and Post-Quantum/Traditional (PQ/T) hybrid solutions for the SSI model based on Decentralized IDentifier (DID), Verifiable Credential (VC), and Verifiable Presentation (VP) data models. The PQ/T hybrid approach leverages a novel type of verification method called CompositeSignaturePublicKey, which exploits the concept of composite public key. This novel type, specifically designed for authentication in SSI ecosystem, provides the Weak Non-Separability (WNS) property of the hybrid signature and performance comparable to the pure PQ approach. Moreover, the PQ/T hybrid approach ensures backward compatibility and today’s level of security in case the selected PQ algorithms are found to be theoretically flawed in the future. The experimental results demonstrate the validity and effectiveness of the open source implementation.
