description: We use the Bethe-Salpeter equation in rainbow-ladder truncation to calculate the ground state mesons from the chiral limit to bottomonium, with an effective interaction that was previously fitted to the chiral condensate and pion decay constant. Our results are in reasonable agreement with the data, as are the vector and pseudoscalar decay constants. The meson mass differences tend to become constant in the heavy-quark limit. We also present calculations for the pion and rho electromagnetic form factors, and for the single-quark form factors of the η_c and J/ψ.

description: Το μάρκετινγκ σχέσεων αλλά και η διαχείριση πελατειακών σχέσεων έχουν λάβει κεντρική θέση στη στρατηγική μάρκετινγκ κατά τις τελευταίες δύο δεκαετίες. Μάρκετινγκ σχέσεων είναι μια στρατηγική που αποσκοπεί στην προώθηση της εμπιστοσύνης των πελατών, την αντίδραση και τη διατήρηση των σχέσεων. Για τις επιχειρήσεις που χρησιμοποιούν ή επιθυμούν να χρησιμοποιήσουν σχέσεις μάρκετινγκ στην επιχείρησή τους, το κύριο ερώτημα είναι, πώς μπορεί να εφαρμοστεί το μάρκετινγκ σχέσεων για τη βελτίωση της εμπιστοσύνης των πελατών και τις πωλήσεις του πωλητή. Ένα βασικό εργαλείο που χρησιμοποιήσαμε και στην εργασία μας είναι η διαχρονική αξία του πελάτη (Customer Lifetime Value-CLV). Ο προσδιορισμός της CLV είναι ένα σημαντικό στοιχείο στη λήψη στρατηγικών αποφάσεων τόσο στη διαφήμιση όσο και στην προώθηση των προϊόντων. Σε αυτή την εργασία προτείνουμε ένα στοχαστικό μοντέλο δυναμικού προγραμματισμού με την διαδικασία λήψης αποφάσεων Markov πρώτης και δεύτερης τάξης για τη βελτιστοποίηση της CLV. Στη συνέχεια το μοντέλο εφαρμόστηκε σε εικονικά δεδομένα μιας εταιρείας εξυπηρέτησης πελατών. Ολοκληρώνοντας την εργασία, τα δύο μοντέλα που συγκρίθηκαν και καταλήξαμε με πιθανές μελλοντικές επεκτάσεις του μοντέλου.
description: Relationship marketing and customer relationship management have taken a central position in marketing strategy in the past two decades. Relationship marketing is a strategy designed to foster customer loyalty, reaction and retention of relationships. For firms who use-or wish to use- relationship marketing in their business, the primary question is, How can relationship marketing be implemented to improve customer loyalty and seller's sales? One basic tool that we also used in our thesis is customer lifetime value (Customer Lifetime Value-CLV). The determination of CLV is an important element in making strategic decision in both advertising and promotion. In this thesis we propose a stochastic dynamic programming with a Markov decision process in the first and second order for the optimization of CLV. The model is then applied to virtual data of a customer service company. Finally, the two models are compared and we conclude with possible future expansions of the above models.

description: We present a method for computing transition points of the random cluster model using a generalization of the Newman-Ziff algorithm, a celebrated technique in numerical percolation, to the random cluster model. The new method is straightforward to implement and works for real cluster weight $q>0$. Furthermore, results for an arbitrary number of values of $q$ can be found at once within a single simulation. Because the algorithm used to sweep through bond configurations is identical to that of Newman and Ziff, which was conceived for percolation, the method loses accuracy for large lattices when $q>1$. However, by sampling the critical polynomial, accurate estimates of critical points in two dimensions can be found using relatively small lattice sizes, which we demonstrate here by computing critical points for non-integer values of $q$ on the square lattice, to compare with the exact solution, and on the unsolved non-planar square matching lattice. The latter results would be much more difficult to obtain using other techniques.

description: Σκοπός της παρούσας διπλωματικής εργασίας ήταν η μελέτη του πώς αυτό-προσδιορίζονται τα παιδιά Ρομά ηλικίας 11-14 χρονών. Η συγκεκριμένη εργασία διενεργήθηκε κατά τη διάρκεια θερινών μαθημάτων για παιδιά Ρομά στη Ρόδο (2011-2013). Κατά τη διάρκεια της εργασίας οι μαθητές είχαν την ευκαιρία μέσα από την ανάγνωση κειμένων να παράγουν δικά τους κείμενα ταυτότητας. Το ενδιαφέρον μας ήταν πώς οι μαθητές θα μπορούσαν να οδηγηθούν στη βελτίωση της γλωσσικής τους ικανότητας και στο γραμματισμό, αλλά και στην ενδυνάμωση της προσωπικότητας τους. Αρχικά, παρουσιάζουμε συνοπτικά τα εκπαιδευτικά προγράμματα που έχουν συντελεστεί τις τρεις τελευταίες δεκαετίες στην Ελλάδα και μετά τη συγκεκριμένη δράση που πραγματοποιήθηκε στη Ρόδο (2011-13). Στη συνέχεια, όσον αφορά στη θεωρητική προσέγγιση, παρουσιάζουμε και επεξεργαζόμαστε την έννοια της κατασκευής νοήματος και της ταυτότητας στα πλαίσια του πολιτισμού και της εκπαίδευσης. Σ’ ότι αφορά στη μεθοδολογική προσέγγιση, παρουσιάζουμε και επεξεργαζόμαστε την έρευνα-δράση και τα εργαλεία που χρησιμοποιήθηκαν για τη διεξαγωγή της. Τέλος, παρουσιάζουμε και σχολιάζουμε τα αποτελέσματα/ συμπεράσματα της έρευνας καταθέτοντας προτάσεις για περαιτέρω έρευνα.
description: The objective of this thesis is to present a study regarding self-definitions of Roma children of 11-14 years of age. The specific project was realized during (a) summer course(s) for Roma children that took place in Rhodes (2011-2013) in the school spaces. During the project the students had the opportunity to read texts and to create their own identity texts. Our concern was to see how students would be supported in their language proficiency and towards literacy and how their personality would be empowered. At the beginning we present the educational programs for Roma students that were carried out in Greece during the last three decades and then we present the specific action that took place in Rhodes (2011-2013). Furthermore, as regards the theoretical approach we present and elaborate the notion of meaning making as well as the notion of identity in cultural and educational contexts. As regards the methodological approach we present and elaborate action-research and the applied tools. At the end we present and discuss our outcomes making suggestions for further research.

description: We investigate what the orbits of globular clusters (GCs) in the Fornax dwarf spheroidal (dSph) galaxy can teach us about dark matter (DM). This problem was recently studied for ultralight dark matter (ULDM). We consider two additional models: (i) fermionic degenerate dark matter (DDM), where Pauli blocking should be taken into account in the dynamical friction computation; and (ii) self-interacting dark matter (SIDM). We give a simple and direct Fokker-Planck derivation of dynamical friction, new in the case of DDM and reproducing previous results in the literature for ULDM and cold DM. ULDM, DDM and SIDM were considered in the past as leading to cores in dSphs, a feature that acts to suppress dynamical friction and prolong GC orbits. For DDM we derive a version of the cosmological free streaming limit that is independent of the DM production mechanism, finding that DDM cannot produce an appreciable core in Fornax without violating Ly-$α$ limits. If the Ly-$α$ limit is discounted for some reason, then stellar kinematics data does allow a DDM core which could prolong GC orbits. For SIDM we find that significant prolongation of GC orbits could be obtained for values of the self-interaction cross section considered in previous works. In addition to reassessing the inspiral time using updated observational data, we give a new perspective on the so-called GC timing problem, demonstrating that for a cuspy cold DM profile dynamical friction predicts a $z=0$ radial distribution for the innermost GCs that is independent of initial conditions. The observed orbits of Fornax GCs are consistent with this expectation with a mild apparent fine-tuning at the level of $\sim25\%$.

description: A decision maker is choosing between an active action (e.g., purchase a house, invest certain stock) and a passive action. The payoff of the active action depends on the buyer's private type and also an unknown state of nature. An information seller can design experiments to reveal information about the realized state to the decision maker, and would like to maximize profit from selling such information. We characterize, in closed-form, the revenue-optimal information selling mechanism for the seller. After eliciting the buyer's type, the optimal mechanism charges the buyer an upfront payment and then simply reveals whether the realized state exceeds a certain threshold or not. The optimal mechanism features both price discrimination and information discrimination. The special buyer type who is a-priori indifferent between the active and passive action benefits the most from participating in the mechanism.

description: Two important classes of quantum structures, namely orthomodular posets and orthomodular lattices, can be characterized in a classical context, using notions like partial information and points of view. Using the formalism of representation systems, we show that these quantum structures can be obtained by expressing conditions on the existence of particular points of view, of particular ways to observe a system.

description: We present a derivation of the numerical phenomenon that differences between the Riemann zeta function's nontrivial zeros tend to avoid being equal to the imaginary parts of the zeros themselves, a property called statistical "repulsion" between the zeros and their differences. Our derivation relies on the statistical properties of the prime zeta function, whose singularity structure specifies the positions of the Riemann zeros. We show that the prime zeta function on the critical line is asymptotically normally distributed with a covariance function that is closely approximated by the logarithm of the Riemann zeta function's magnitude on the 1-line. This creates notable negative covariance at separations approximately equal to the imaginary parts of the Riemann zeros. This covariance function and the singularity structure of the prime zeta function combine to create a conditional statistical bias at the locations of the Riemann zeros that predicts the zero-difference repulsion effect. Our method readily generalizes to describe similar effects in the zeros of related L-functions.

description: Pt‐based alloy catalysts supported on carbon are commonly characterized for oxygen reduction reaction (ORR) activity using the rotating disk electrode technique (RDE). Within this study, we show exemplarily for PtNiMo/C catalysts that the applied pretreatment influences strongly the determined activity. The classically employed descriptor of unchanged cyclic voltammetry response is insufficient to portrait completed surface restructuring, and gives an incorrect impression that stable activity can be determined. This might be one of the reasons for the strongly deviating activities reported in literature. Following the changes in activity during pretreatment also with in‐situ FTIR and online dissolution measurements gives insights to an up to now largely overseen high activity of the trimetallic catalysts. A maximum activity of 0.57 mA cmPt⁻² at 0.95 VRHE is reached quickly during the first six cycles and decreases slowly subsequently. The maximum activity and change of activity over the cycle number is affected by the scan rate and electrolyte refreshing, while the gas atmosphere plays only a minor role. This exemplary study might be important for Pt alloy catalysts in general.

description: The issue of ergodicity is often underestimated. The presence of zero-frequency excitations in bosonic Green's functions determine the appearance of zero-frequency momentum-dependent quantities in correlation functions. The implicit dependence of matrix elements make such quantities also relevant in the computation of susceptibilities. Consequently, the correct determination of these quantities is of great relevance and the well-established practice of fixing them by assuming the ergodicity of the dynamics is quite questionable as it is not justifiable a priori by no means. In this manuscript, we have investigated the ergodicity of the dynamics of the $z$-component of the spin in the 1D Heisenberg model with anisotropic nearest-neighbor and isotropic next-nearest-neighbor interactions. We have obtained the zero-temperature phase diagram in the thermodynamic limit by extrapolating Exact and Lanczos diagonalization results computed on chains with sizes $L = 6 ÷26$. Two distinct non-ergodic regions have been found: one for $J^\prime/J_z \lesssim 0.3$ and $|J_\perp|/J_z < 1$ and another for $J^\prime/J_z \lesssim 0.25$ and $|J_\perp|/J_z = 1$. On the contrary, finite-size scaling of $T \neq 0$ results, obtained by means of Exact diagonalization on chains with sizes $L = 4 ÷18$, indicates an ergodic behavior of dynamics in the whole range of parameters.

Structural adjustment in India: economic crisis and policy choice
Creators: name: Samuel, Ava Lillian
Publisher: name: University of British Columbia
Year: 2009

description: The decision to undertake a structural adjustment program usually comes at a time when a country is facing a severe economic crisis. In India, the conditions surrounding the economic crisis of 1991 left Indian policy-makers with little alternative but to pursue liberal economic policies. This thesis examines three aspects of India's economic crisis, political, economic and international, in an attempt to explain the Narasimha Rao government's policy choice. Three dimensions of the decision - timing, scope, and content - are used to simplify the analysis, and to measure the contributions of various factors. Whereas the ideology and international systems explanations only play an indirect role in India's policy choice, I argue that convergence of factors highlighted by the interest group, political institutional and international financial institutional explanations resulted in India's decision to liberalize its economy.

description: We demonstrate fast and ultrasensitive charge detection with a cavity-embedded Cooper pair transistor (cCPT) via dispersive readout of its Josephson inductance. We report a minimum charge sensitivity of $14$ $μe/\sqrt{\mathrm{Hz}}$ with a detection bandwidth on the order of $1$ MHz using $16$ attowatts of power, corresponding to the single-photon level of the cavity. In addition, our measured sensitivities are within a factor of $5$ of the quantum limit for this device. The single-photon-level sensitivity of the cCPT is comparable to that of the rf-SET, which typically operates using picowatts of power corresponding to hundreds of thousands of photons in its tank circuit. Our results support the feasibility of using the cCPT to mediate an optomechanical interaction that reaches the single-photon strong coupling regime.

description: The thermodynamics of massless ideal gas of overlap quarks has been investigated both analytically and numerically for both zero and nonzero baryon chemical potential. Any μ^2-divergence is shown analytically to be absent for a class of actions with nonzero chemical potential. All such actions are shown to violate chiral invariance. While the parameter M can be shown to be irrelevant in the continuum limit, as expected, it is shown numerically that the continuum limit can be reached with relatively coarser lattices for certain ranges of M. Numerical limitations of the existing method of introduction of chemical potential are demonstrated. Finally we also show that the energy density for the massive overlap fermions has the correct continuum limit.

Galaxies with unusually high abundances of molecular hydrogen

description: A sample of 66 galaxies from the catalog of Bettoni et al. (CISM) with anomalously high molecular-to-atomic hydrogen mass ratios (M_{mol}/M_{HI}>2) is considered. The sample galaxies do not differ systematically from other galaxies in the catalog with the same morphological types, in terms of their photometric parameters, rotational velocities, dust contents, or the total mass of gas in comparison with galaxies of similar linear sizes and disk angular momentum. This suggests that the overabundance of $H_2$ is due to transition of HI to H_2. Galaxies with bars and active nuclei are found more frequently among galaxies which have M_{mol} estimates in CISM. In a small fraction of galaxies, high M_{mol}/M_{HI} ratios are caused by the overestimation of M_{mol} due to a low conversion factor for the translation of CO-line intensities into the number of H_2 molecules along the line of sight. It is argued that the "molecularization" of the bulk of the gas mass could be due 1) to the concentration of gas in the inner regions of the galactic disks, resulting to a high gas pressure and 2) to relatively low star-formation rate per unit mass of molecular gas which indeed takes place in galaxies with high M_{mol}/M_{HI} ratios.

description: A four electrode electrostatic trap geometry is demonstrated that can be used to combine a dipole, quadrupole and hexapole field. A cold packet of 15ND3 molecules is confined in both a purely quadrupolar and hexapolar trapping field and additionally, a dipole field is added to a hexapole field to create either a double-well or a donut-shaped trapping field. The profile of the 15ND3 packet in each of these four trapping potentials is measured, and the dependence of the well-separation and barrier height of the double-well and donut potential on the hexapole and dipole term are discussed.

In this work we introducing a variety of pairwise symmetry breaking constraints, specific to k-robust planning, that can efficiently find compatible and optimal paths for pairs of conflicting agents. We give a thorough description of the new constraints and report large improvements to success rate ina range of domains including: (i) classic MAPF benchmarks;(ii) automated warehouse domains and; (iii) on maps from the 2019 Flatland Challenge, a recently introduced railway domain where k-robust planning can be fruitfully applied to schedule trains.

Orbis pictus to hypertext: a quest for a self-directed multimedia German acquisition programme
Creators: name: Ross, Ingrid
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates the research area of the formation of a self-directed, interactive multimedia, German acquisition programme, intended for first-year university students. Chapter 1 introduces the thesis by discussing the methodology, which is chiefly historical and analytic; by surveying the relevant literature; and by advancing a rationale for the study. Since the thesis emphasizes a historical dimension, Chapter 2 presents research on the career of the seventeenthcentury education reformer Comenius, who is identified as the first systematic theorist of language didactics. His seminal ideas and textbooks connected with language acquisition (LA), which prefigure much in contemporary practice, have been unjustly neglected, and the thesis is intended in part to help correct this situation. Chapter 3 offers research on a historical panorama of landmark theory in linguistics and applied linguistics from Comenius’ time to ours, to explore significant ideas that help to shape LA programmes. From the joint perspective of Comenian didactics and modern philosophy of curriculum, Chapter 4 analyses textbooks now or recently in use in a first-year university German course to derive guidelines, principally from the communicative approach, for the proposed German programme. Chapter 5 synthesizes leading ideas gained from study of Comenius and arising from first-hand investigation of later theorists, also it brings in awareness of the possibilities of interactive multimedia, to present an original outline of a self-directed German programme as a contribution to research on second language acquisition. Appendix A presents pictures illustrating the far off intellectual world of Comenius. Appendix B reports on practices and resources at innovative university language centres in Germany and Britain, and surveys some self-directed LA programmes, but chiefly W.E. Mackey’s multimedia self-directed English LA version for Francophone children in New Brunswick, to establish the main features of what is being called the post-communicative approach to LA.

description: The present master study deals with the attacks against computer systems through a technical perspective and legal approach on a level of European Union and Greek criminal law legislation. In the first part, that deals with technical perspective, attacks like SYN flood, DoS, Man-in-the-middle, port scan etc. are being discussed. In the second part, there is a comparative analysis of relating provisions of the Cybercrime Convention, the Council Framework Decision 2005/222/EU on attacks against computer systems, and also of the -recently adopted- 2013/40/EU Directive of the European Parliament and of the Council on attacks against computer systems, replacing the abovementioned Council Framework Decision. Finally, in the third part, already existing provisions of Greek substantial criminal law that could lead to criminalization of attacks against computer systems are being discussed, while some thoughts on the proposed new draft of Greek Criminal Code are committed to paper.

description: Being reformulated in the color dipole basis of small-x QCD Adler's theorem establishes a connection between perturbative and non-perturbative descriptions of DIS and quantifies the effect of non-perturbative dynamics on would-be-perturbative observables. In particular, it provides a quantitative measure of the non-perturbative influence on the longitudinal structure function in charged current DIS and imposes stringent constraints on non-perturbative parameters of color dipole models. Our analysis calls for new experimental tests of Adler's theorem in diffractive neutrino scattering.

description: We analyse the Higgs sector of an $S_3$ model with three Higgs doublets and no CP violation. After electroweak breaking there are nine physical Higgs bosons, one of which corresponds to the Standard Model one. We study the scalar and gauge sectors of this model, taking into account the conditions set by the minimisation and stability of the potential. We calculate the masses, trilinear and quartic Higgs-Higgs, and Higgs-gauge couplings. We consider two possible alignment scenarios, where only one of the three neutral scalars has couplings to the gauge bosons and corresponds to the SM Higgs, and whose trilinear and quartic couplings reduce exactly to the SM ones. We also obtain numerically the allowed parameter space for the scalar masses in each of the alignment scenarios. We use the calculated trilinear and quartic couplings to find the analytical structure of the one-loop neutral scalar mass matrix, without fermionic contributions. We show that it is possible to have a compact mass spectrum where the contribution to the oblique parameters might be small. We explore some scenarios for the loop contributions to the neutral scalar masses.

description: We propose a straightforward implementation of the phenomenon of diffractive focusing with uniform atomic Bose-Einstein condensates. Both, analytical as well as numerical methods not only illustrate the influence of the atom-atom interaction on the focusing factor and the focus time, but also allow us to derive the optimal conditions for observing focusing of this type in the case of interacting matter waves.

description: To elucidate the relationship between a crystal's structure, its thermal conductivity, and its phonon dispersion characteristics, an analysis is conducted on layered diatomic Lennard-Jones crystals with various mass ratios. Lattice dynamics theory and molecular dynamics simulations are used to predict the phonon dispersion curves and the thermal conductivity. The layered structure generates directionally dependent thermal conductivities lower than those predicted by density trends alone. The dispersion characteristics are quantified using a set of novel band diagram metrics, which are used to assess the contributions of acoustic phonons and optical phonons to the thermal conductivity. The thermal conductivity increases as the extent of the acoustic modes increases, and decreases as the extent of the stop bands increases. The sensitivity of the thermal conductivity to the band diagram metrics is highest at low temperatures, where there is less anharmonic scattering, indicating that dispersion plays a more prominent role in thermal transport in that regime. We propose that the dispersion metrics (i) provide an indirect measure of the relative contributions of dispersion and anharmonic scattering to the thermal transport, and (ii) uncouple the standard thermal conductivity structure-property relation to that of structure-dispersion and dispersion-property relations, providing opportunities for better understanding of the underlying physical mechanisms and a potential tool for material design.

Symbolic Models for Infinite Networks of Control Systems: A Compositional Approach

description: This paper presents a compositional framework for the construction of symbolic models for a network composed of a countably infinite number of finite-dimensional discrete-time control subsystems. We refer to such a network as infinite network. The proposed approach is based on the notion of alternating simulation functions. This notion relates a concrete network to its symbolic model with guaranteed mismatch bounds between their output behaviors. We propose a compositional approach to construct a symbolic model for an infinite network, together with an alternating simulation function, by composing symbolic models and alternating simulation functions constructed for subsystems. Assuming that each subsystem is incrementally input-to-state stable and under some small-gain type conditions, we present an algorithm for orderly constructing local symbolic models with properly designed quantization parameters. In this way, the proposed compositional approach can provide us a guideline for constructing an overall symbolic model with any desired approximation accuracy. A compositional controller synthesis scheme is also provided to enforce safety properties on the infinite network in a decentralized fashion. The effectiveness of our result is illustrated through a road traffic network consisting of infinitely many road cells.

description: Στην παρούσα διπλωματική εργασία περιγράφεται ο σχεδιασμός και η παρασκευή δύο εναντιομερών 18-αιθέρων-στεμμάτων-6 (διμερών της myo-ινοσιτόλης), σε 7 στάδια και πρώτη ύλη τη myo-ινοσιτόλη, που θα χρησιμοποιηθούν μεταγενέστερα ως καταλύτες μεταφοράς φάσης σε στερεοεκλεκτικές αντιδράσεις. Σημαντικό ενδιάμεσο της σύνθεσης ήταν η δικετάλη (±)-(2,3),(4,5)-δι-Ο-κυκλοεξυλιδενο-myo-ινοσιτόλη. Κομβικά σημεία αποτέλεσαν ο διαχωρισμός της δικετάλης αυτής από τα regio-ισομερή της, ο διαχωρισμός των εναντιομερών της και η εκλεκτική προστασία των υδροξυλίων της. Το πρώτο επετεύχθη με κρυστάλλωση ενός προστατευμένου παραγώγου της, το δεύτερο με την εισαγωγή κατάλληλης χειρόμορφης ομάδας και το τρίτο με τη χρήση κασσιτερικών κεταλών. Η σύνθεση ολοκληρώθηκε εφαρμόζοντας ένα γραμμικό σχήμα σύνδεσης των δύο ινοσιτολικών μονάδων.
description: In this dissertation, the design and synthesis of two enantiomers of 18-crown-ethers-6 (dimers of myo-inositol), in 7 steps and using myo-inositol as the starting material, which will be subsequently used as phase transfer catalysts in stereoselective reactions. Important intermediate in the synthesis is the diketal (±)-(2,3),(4,5)-bis-Ο-cyclohexylidene-myo-inositol. Κey points were the separation of this diketal from it regioisomers, the separation of its enantiomers and the selective protection of its hydroxyls. The first goal was realized with crystallization of a protected derivative, the second one with the introduction of a chiral group and the third with the employment of tin acetals. The synthesis was completed applying a linear protocol in order to connect the two inositol units.
