description: The intensity of Smith-Purcell radiation from metallic and dielectric gratings (silicon, silica) is compared in a frequency-domain simulation. The numerical model is discussed and verified with the Frank-Tamm formula for Cherenkov radiation. For 30 keV electrons, rectangular dielectric gratings are less efficient than their metallic counterpart, by an order of magnitude for silicon, and two orders of magnitude for silica. For all gratings studied, radiation intensity oscillates with grating tooth height due to electromagnetic resonances in the grating. 3D and 2D numerical models are compared.

description: Σκοπός της παρούσης εργασίας ήταν να αναδειχθεί το δικαίωμα των παιδιών με ειδικές ανάγκες στην αγωγή και την εκπαίδευση, καθώς και ο ρόλος των δυο σημαντικότερων παραγόντων για την ανατροφή τους, που είναι η οικογένεια και το σχολείο. Αρχικά εξετάσαμε την σημασιολογική προσέγγιση και τη διευκρίνιση της ορολογίας που χρησιμοποιήθηκε, καθώς και την ισχύουσα νομοθεσία που κατοχυρώνει την συνεργασία των δυο φορέων. Στη συνέχεια ασχοληθήκαμε με την αναγκαιότητα της συνεργασίας και την επίδραση προς τα παιδιά, ενώ παράλληλα έγινε μια αναφορά στα μοντέλα μέσω των οποίων μπορεί να επιτευχθεί. Έπειτα επιχειρήθηκε ο προσδιορισμός των διαπροσωπικών σχέσεων γονέων – εκπαιδευτικών. Τέλος αναφερθήκαμε μέσα από την πατερική παράδοση, στις στάσεις του Χριστιανισμού και της ορθόδοξης Εκκλησίας προς τα άτομα με ειδικές ανάγκες, καθώς επίσης και στον ηθικό προβληματισμό μιας διαπιστωμένης κύησης παιδιού με ειδικές ανάγκες.
description: The aim of the present work was to highlight the right of children with special needs to education, as well as the role of the two major factors of their upbringing which are family and school. Firstly, we studied the semantic approach and the clarification of terminology used, as well as the existing law which guarantees the cooperation between the two factors. Secondly, we examined the necessity of this cooperation and its effect to the children, while there was a reference to the models through which the cooperation can be achieved. Then we attempted to identify the interpersonal relation between parents and teachers. Finally, we referred to the Christianity and the Orthodox Church attitude towards disabled people, through the patristic tradition, as well as to the moral reflection concerning a diagnosed pregnancy of a special child.

Στη συνάφεια αυτή λαμβάνεται υπόψην η άποψη της σύγχρονης Ψυχολογίας και Παιδαγωγικής, ενώ τονίζεται η συμβολή των επιστημών αυτών στην ηθική ανάπτυξη του παιδιού και του εφήβου. Προβάλλονται οι απόψεις των J. Piaget, L. Kohlberg, A. Bandura, B. Skinner, καθώς και των σημαντικότερων Ελλήνων παιδαγωγών. Στη συνέχεια, παρουσιάζουμε την προσέγγιση της Χριστιανικής Ηθικής σχετικά με την ελευθερία και την ηθική ανάπτυξη του ανθρώπου. Οι θέσεις της Χριστιανικής Ηθικής αντιπαραβάλλονται με τις αντιλήψεις που επικρατούν στη σύγχρονη κοινωνία. Στη συνάφεια αυτή δίνεται έμφαση στη διδασκαλία των Τριών Ιεραρχών σχετικά με την αγωγή και την ηθική διάπλαση του χαρακτήρα του παιδιού από τους γονείς και τους δασκάλους. Τέλος, η εργασία ολοκληρώνεται με αναφορά στη σημασία του μαθήματος των θρησκευτικών στο σχολείο, καθώς κρίνεται ότι αυτό βοηθά στην ηθική ανάπτυξη και στην ελεύθερη κριτική άποψη του μαθητή.
description: The present project begins with a classical presentation of various theories, which were put forward about the value of ethics education and freedom that a child and an adolescent could develop. After that, this project presents the different stages of child’s and adolescent’s maturity throughout the development of morality. In this context, we take into consideration the view of modern Psychology and Pedagogy, while we mention the contribution of these scientists in children’s and adolescents’ moral development. Shown are views of J. Piaget, L. Kohlberg, A. Bandura, B. Skinner, and the most important Greek educators. Then, we present the approach of Christian Ethics on freedom and moral development of man. Christian Ethics’ vies are in contrast with the perceptions of modern society. In relevance with the above, we emphasize on teaching the Three Hierarchs on the education and moral formation of a child’s character by parents and teachers. Finally, this project ends with reference to the importance of religious education at school, believing that it embraces students’ moral development and free critical view.

description: Strange nonchaotic attractors (SNAs) have been identified and studied in the literature exclusively in quasiperiodically driven nonlinear dynamical systems. It is an interesting question to ask whether they can be identified with other types of forcings as well, which still remains as an open problem. Here, we show that robust SNAs can be created by a small amount of noise in periodically driven nonlinear dynamical systems by a single force. The robustness of these attractors is tested by perturbing the system with logical signals leading to the emulation of different logical elements in the SNA regions.

description: We address the phase space formulation of a noncommutative extension of quantum mechanics in arbitrary dimension, displaying both spatial and momentum noncommutativity. By resorting to a covariant generalization of the Weyl-Wigner transform and to the Seiberg-Witten map we construct an isomorphism between the operator and the phase space representations of the extended Heisenberg algebra. This map provides a systematic approach to derive the entire structure of noncommutative quantum mechanics in phase space. We construct the extended starproduct, Moyal bracket and propose a general definition of noncommutative states. We study the dynamical and eigenvalue equations of the theory and prove that the entire formalism is independent of the particular choice of Seiberg-Witten map. Our approach unifies and generalizes all the previous proposals for the phase space formulation of noncommutative quantum mechanics. For concreteness we rederive these proposals by restricting our formalism to some 2-dimensional spaces.

description: The topic of this thesis is the petition for annulment of criminal proceedings. The petition for annulment is a legal remedy given to the defendant who, for reasons of force majeur, did not manage to notify the court about an insuperable obstacle concerning his/her appearance before it and request the abjournment of the trial, resulting in his/her conviction by default. The petition arises from the principle quoting “impossibilium nulla est obligatio” and intends to protect the convicted by default defendant’s right to be heard. The aim of the petition is the annulment of the court proceedings performed without his/her presence and the repetition in his/her presence. The petition can be filed against convictions for serious offences (article 341 of the Code of Criminal Procedure) or felonies (article 435 of the CCP). It can be also filed against judgments of Courts of Appeals (art. 501 § 1 of the CCP). The preconditions of the petition, the field of its application as well as the failure of the relevant regulations that result in the restriction of the defendant’ s right to be heard are discussed in this thesis.

description: Dispersionless bands -- \emph{flatbands} -- provide an excellent testbed for novel physical phases due to the fine-tuned character of flatband tight-binding Hamiltonians. The accompanying macroscopic degeneracy makes any perturbation relevant, no matter how small. For short-range hoppings flatbands support compact localized states, which allowed to develop systematic flatband generators in $d=1$ dimension in Phys. Rev. B {\bf 95} 115135 (2017) and Phys. Rev. B {\bf 99} 125129 (2019). Here we extend this generator approach to $d=2$ dimensions. The \emph{shape} of a compact localized state turns into an important additional flatband classifier. This allows us to obtain analytical solutions for classes of $d=2$ flatband networks and to re-classify and re-obtain known ones, such as the checkerboard, kagome, Lieb and Tasaki lattices. Our generator can be straightforwardly generalized to three lattice dimensions as well.

description: The electronic and magnetic properties of the cubic double perovskite Ba2NaOsO6 were examined by performing first-principles density functional theory calculations and analyzing spin-orbit coupled states of an Os7+ (d1) ion at an octahedral crystal field. The insulating behavior of Ba2NaOsO6 was shown to originate from a cooperative effect of electron correlation and spin-orbit coupling. This cooperative effect is responsible not only for the absence of orbital ordering in Ba2 NaOsO6 but also for a small magnetic moment and a weak magnetic anisotropy in Ba2NaOsO6.

description: In the local Universe, there is a handful of dwarf compact star-forming galaxies with extremely low oxygen abundances. It has been proposed that they are young, having formed a large fraction of their stellar mass during their last few hundred Myr. However, little is known about the fraction of young stellar populations in more massive galaxies. In a previous article, we analyzed 280 000 SDSS spectra to identify a surprisingly large sample of more massive Very Young Galaxies (VYGs), defined to have formed at least $50\%$ of their stellar mass within the last 1 Gyr. Here, we investigate in detail the properties of a subsample of 207 galaxies that are VYGs according to all three of our spectral models. We compare their properties with those of control sample galaxies (CSGs). We find that VYGs tend to have higher surface brightness and to be more compact, dusty, asymmetric, and clumpy than CSGs. Analysis of a subsample with HI detections reveals that VYGs are more gas-rich than CSGs. VYGs tend to reside more in the inner parts of low-mass groups and are twice as likely to be interacting with a neighbour galaxy than CSGs. On the other hand, VYGs and CSGs have similar gas metallicities and large scale environments (relative to filaments and voids). These results suggest that gas-rich interactions and mergers are the main mechanisms responsible for the recent triggering of star formation in low-redshift VYGs, except for the lowest mass VYGs, where the starbursts may arise from a mixture of mergers and gas infall.

description: The triad refers to embedding the Macdonald polynomials into the Noumi-Shiraishi functions and their reduction to solutions of simple linear equations at particular values of $t$. It provides an alternative definition of Macdonald theory. We discuss lifting the triad to an elliptic generalization of the Noumi-Shiraishi functions. The central unknown ingredient is linear equations, for which we discuss various possible approaches, including immediate elliptic deformation of periodicity conditions, (elliptic) Ding-Iohara-Miki algebra operators, and elliptic Kostka coefficients.

description: Clusters of galaxies and the large scale filaments that connect neighboring clusters are expected to be sites of acceleration of charged particles and sources of non-thermal radiation from radio frequencies to gamma rays. Gamma rays are particularly interesting targets of investigation, since they may provide precious information on the nature and efficiency of the processes of acceleration and magnetic confinement of hadrons within clusters of galaxies. Here we review the status of viable scenarios that lead to the production of gamma rays from large scale structures and are compatible with the multifrequency observations that are already available. We also discuss the possibility of detection of gamma rays with space-borne telescopes such as GLAST and ground based Cherenkov telescopes, and the physical information that may be gathered from such observations.

Fraunhofer oscillations of the critical current at a varying Zeeman field in a spin-orbit coupled Josephson junction

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The Zeeman interaction results in spontaneous current through a Josephson contact with a spin-orbit coupled normal metal, even in the absence of any voltage, or phase bias. In the case of the Rashba spin orbit coupling of electrons in a two-dimensional (2D) electron gas this effect takes place for the Zeeman field which is parallel to the 2D system and to superconducting contacts. At the same time, the spontaneous current is absent when this field is perpendicular to the contacts. It is shown that in the latter case it may manifest itself in oscillations of the critical Josephson current at the varying Zeeman energy. These oscillations have a form of the Fraunhofer diffraction pattern. The Josephson current under the phase bias was calculated based on the semiclassical Green functions for a disordered 2D electron gas with the strong spin orbit coupling, as well as for surface electrons of a three dimensional topological insulator. In the latter case the diffraction pattern was found to be most pronounced, while in the Rashba gas the oscillations of the critical current are weaker.

description: The quantum advantage of dense coding is studied, considering general encoding quantum operations. Particular attention is devoted to the case of many senders, and it is shown that restrictions on the possible operations on the senders' side may make some quantum state useless for dense-coding. It is shown, e.g., that some states are useful for dense coding if the senders can communicate classically (but not quantumly), yet they cannot be used for dense coding, if classical communication is not allowed. These no-go results are actually independent of the particular quantification of the quantum advantage, being valid for any reasonable choice. It is further shown that the quantum advantage of dense coding satisfies a monogamy relation with the so-called entanglement of purification.

description: We examine rotational transitions of HCl in collisions with H$_2$ by carrying out quantum mechanical close-coupling and quasi-classical trajectory calculations on a recently developed globally accurate full-dimensional ab initio potential energy surface for the H$_3$Cl system. Signatures of rainbow scattering in rotationally inelastic collisions are found in the state resolved integral and differential cross sections as functions of the impact parameter (initial orbital angular momentum) and final rotational quantum number. We show the coexistence of distinct dynamical regimes for the HCl rotational transition driven by the short-range repulsive and long-range attractive forces whose relative importance depends on the collision energy and final rotational state suggesting that classification of rainbow scattering into rotational and $l$-type rainbows is effective for H$_2$+HCl collisions. While the quasi-classical trajectory method satisfactorily predicts the overall behavior of the rotationally inelastic cross sections, its capability to accurately describe signatures of rainbow scattering appears to be limited for the present system.

description: Quasi-realistic string models in the free fermionic formulation typically contain an anomalous U(1), which gives rise to a Fayet-Iliopoulos D-term that breaks supersymmetry at the one--loop level in string perturbation theory. Supersymmetry is traditionally restored by imposing F- and D-flatness on the vacuum. By employing the standard analysis of flat directions we present a quasi--realistic three generation string model in which stringent F- and D-flat solution do not appear to exist to all orders in the superpotential. We speculate that this result is indicative of the non-existence of supersymmetric flat F- and D-solutions in this model. We provide some arguments in support of this scenario and discuss its potential implications. Bose-Fermi degeneracy of the string spectrum implies that the one--loop partition function and hence the one-loop cosmological constant vanishes in the model. If our assertion is correct, this model may represent the first known example with vanishing cosmological constant and perturbatively broken supersymmetry. We discuss the distinctive properties of the internal free fermion boundary conditions that may correspond to a large set of models that share these properties. The geometrical moduli in this class of models are fixed due to asymmetric boundary conditions, whereas absence of supersymmetric flat directions would imply that the supersymmetric moduli are fixed as well and the dilaton may be fixed by hidden sector nonperturbative effects.

description: Η συνεχής αύξηση των απαιτήσεων σε ποικίλες εφαρμογές, για ταχύτερες και υψηλότερες αποδόσεις, οδηγεί στο σχεδιασμό των πολυεπεξεργαστικών συστημάτων. Ανεξάρτητα από την απόδοση ενός επεξεργαστή, η συνεργασία του με έναν ή περισσότερους επεξεργαστές υπόσχεται μεγαλύτερες αποδόσεις. Στα πολυεπεξεργαστικά συστήματα κάθε επεξεργαστής εκτελεί ανεξάρτητα μέρος του συνόλου της εργασίας, και επικοινωνεί με τους υπόλοιπους για να συγχρονίζονται και να όλοι μαζί να δίνουν ένα αποτέλεσμα, πιο ικανοποιητικό από αυτό που θα έδινε ένας επεξεργαστής από μόνος του. Αντικείμενο της εργασίας αυτής, είναι η ανίχνευση ακμών σε εικόνες με τη μέθοδο του Canny. Θα γίνει εφαρμογή του αλγορίθμου του Canny σε επεξεργαστή Microblaze του FPGA που βρίσκεται πάνω στην πλακέτα Virtex 5 (xupv5 lx110t) της εταιρίας Xilinx. Θα μετρηθεί ο χρόνος που απαιτείται σε έναν επεξεργαστή χωρίς, αλλά και με την επικάλυψη των σταδίων του Canny. Στη συνέχεια θα δημιουργηθούν δύο συστήματα τα οποία θα αποτελούνται από δύο επεξεργαστές. Στο πρώτο, ο αλγόριθμος θα μοιραστεί στους δύο επεξεργαστές οι οποίοι θα λειτουργούν ταυτόχρονα, και θα μετρηθεί ξανά ο χρόνος εκτέλεσης. Στο δεύτερο, ο αλγόριθμος θα μοιραστεί στους δύο επεξεργαστές, με τη διαφορά όμως ότι σε αυτή την περίπτωση, ο ένας επεξεργαστής θα εκτελεί μόνο τις εντολές του σταδίου που απαιτεί τον περισσότερο χρόνο.
description: The continuous increase of the demands for faster and higher performance in a variety of implementations, leads to the multiprocessors systems design. Regardless of a processor's performance, its cooperation with one or more processors promises greater performances. In a multiprocessor system every processor independently executes a part of the project and communicates with the rest processors so that they are synchronized and all together give a result, more sufficient than the one a processor alone would give. Object of this thesis is Canny edge detection. Canny's algorithm will be implemented on a Virtex5 (xupv5 lx110t) - FPGA Microblaze processor. The execution time of the algorithm will be counted in two ways, with and without overlap. Afterwards, two systems of two processors will be created and the time of execution will be counted again. In the first one, the algorithm is going to be divided into the two processors, which will work simultaneously. In the second one, the algorithm is going to be divided into the two processors again, but difference will be, that in this case, one of the processors will execute only the most computational intensive part of the algorithm.
Suppressing Frequency Fluctuations of Self-Sustained Vibrations in Underdamped Nonlinear Resonators

description: We consider frequency fluctuations in self-sustained oscillators based on nonlinear underdamped resonators. An important type of such resonators are nano- and micro-electro-mechanical systems. Various noise sources are considered, with the emphasis on the fundamentally unavoidable noise that comes along with dissipation from the coupling to a thermal reservoir. The formulation in terms of the action-angle variables of the resonator allows us to study a deeply nonlinear regime. In this regime the vibration frequency as a function of the action can have an extremum. We show that frequency fluctuations can be strongly reduced by choosing the operation point at this extremum. We suggest a practical implementation of a nanoresonator that has the appropriate property and show explicit results for the corresponding model.

description: A three-atom molecule AAB, formed by two identical bosons A and a distinct one B, is studied by considering coupled channels close to a Feshbach resonance. It is assumed that the subsystems AB and AA have, respectively, one and two channels, where, in this case, AA has open and closed channels separated by an energy gap. The induced three-body interaction appearing in the single channel description is derived using the Feshbach projection operators for the open and closed channels. An effective three-body interaction is revealed in the limit where the trap setup is tuned to vanishing scattering lengths . The corresponding homogeneous coupled Faddeev integral equations are derived in the unitarity limit. The s-wave transition matrix for the AA subsystem is obtained with a zero-range potential by a subtractive renormalization scheme with the introduction of two finite parameters, besides the energy gap. The effect of the coupling between the channels in the coupled equations is identified with the energy gap, which essentially provides an ultraviolet scale that competes with the van der Waals radius - this sets the short-range physics of the system in the open channel. The competition occurring at short distances exemplifies the violation of the ``van der Waals universality" for narrow Feshbach resonances in cold atomic setups. In this sense, the active role of the energy gap drives the short-range three-body physics.

Charge Order and the Origin of Giant Magnetocapacitance in LuFe2O4

description: The nature of the charge order in the charge frustrated compound LuFe$_2$O$_4$ and its effect on magnetocapacitance were examined on the basis of first-principles electronic structure calculations and Monte Carlo simulations of electrostatic energy. Our work shows that two different types of charge order of almost equal stability (i.e., $\sqrt{3}\times \sqrt{3}$ and chain types) occur in the W-layers of LuFe$_2$O$_4$, and that the ground state of LuFe$_2$O$_4$ has a ferrielectric arrangement of the W-layers with $\sqrt{3}\times \sqrt{3}$ charge order. The giant magnetocapacitance effect of LuFe$_2$O$_4$ at room temperature is accounted for in terms of charge fluctuations arising from the interconversion between the two types of charge order, that becomes hindered by an applied magnetic field.

description: We investigate the production of the fully - heavy tetraquark states $T_{4Q}$ in the $γγ$ interactions present in proton-proton, proton-nucleus and nucleus-nucleus collisions at the CERN Large Hadron Collider (LHC). We focus on the $γγ\rightarrow {\cal{Q}}{\cal{Q}}$ (${\cal{Q}} = J/ψ,\, Υ$) subprocess, mediated by the $T_{4Q}$ resonance in the $s$ - channel, and present predictions for the hadronic cross sections considering the kinematical ranges probed by the ALICE and LHCb Collaborations. Our results demonstrate that the experimental study of this process is feasible and can be used to investigate the existence and properties of the $T_{4c}(6900)$ and $T_{4b}(19000)$ states.

description: In a previous work we showed that large nongaussianities and nonscale-invariant distortions in the CMB power spectrum can be generated in hybrid inflation models, due to the contributions of the tachyon (waterfall) field to the second order curvature perturbation. Here we clarify, correct, and extend those results. We show that large nongaussianity occurs only when the tachyon remains light throughout inflation, whereas n=4 contamination to the spectrum is the dominant effect when the tachyon is heavy. We find constraints on the parameters of warped-throat brane-antibrane inflation from nongaussianity. For F-term and D-term inflation models from supergravity, we obtain nontrivial constraints from the spectral distortion effect. We also establish that our analysis applies to complex tachyon fields.

description: We investigate flows interacting with a square and a fractal shape multi-scale structures in the compressible regime for Mach numbers at subsonic and supersonic upstream conditions using large-eddy-simulations (LES). We also aim at identifying similarities and differences that these interactions have with corresponding interactions in the canonical incompressible flow problem. To account for the geometrical complexity associated with the fractal structures, we apply an immersed boundary method to model the no-slip boundary condition at the solid surfaces, with adequate mesh resolution in the vicinity of the small fractal features. We validate the numerical results through extensive comparisons with experimental wind tunnel measurements at a low Mach number. Similar to the incompressible flow case results, we find a break-up of the flow structures by the fractal plate and an increase in turbulent mixing in the downstream direction. As the Mach number increases, we observe noticeable wake meandering and higher spread rate of the wake in the lateral direction perpendicular to the streamwise-spanwise plane. Although not significant, we quantify the difference between the square and the fractal plates using two-point velocity correlations across the Mach number range. The wakes generated by the fractal plate in the compressible regime showed lower turbulent kinetic energy (TKE) and energy spectra levels compared to those of the square case. Moreover, results in terms of the near-field pressure spectra seem to indicate that the fractal plate has the potential to reduce the aerodynamic noise.

description: We compute the fidelity between the ground states of general quadratic fermionic hamiltonians and analyze its connections with quantum phase transitions. Each of these systems is characterized by a $L\times L$ real matrix whose polar decomposition, into a non-negative $Λ$ and a unitary $T$, contains all the relevant ground state (GS) information. The boundaries between different regions in the GS phase diagram are given by the points of, possibly asymptotic, singularity of $Λ$. This latter in turn implies a critical drop of the fidelity function. We present general results as well as their exemplification by a model of fermions on a totally connected graph.
