description: Η εξέταση των νωτιαίων αντανακλαστικών θεωρείται στοιχειώδης για την ταξινόμηση της αλλοίωσης ως τύπου άνω ή κάτω κινητικού νευρώνα σε περιστατικά μυελοπάθειας. Ωστόσο, η εξέτασή τους δεν είναι πάντα εφικτή εξαιτίας της απουσίας συνεργασίας εκ μέρους του σκύλου. Στην παρούσα εργασία διερευνήθηκε η αξιοπιστία της εξέτασης των αντανακλαστικών επιγονατίδας και κάμψης υπό ηρέμηση με τέσσερα διαφορετικά αναισθητικά πρωτόκολλα. Τα αναισθητικά πρωτόκολλα που χρησιμοποιήθηκαν ήταν: το 1ο δεξμεδετομιδίνη σε δόση 180 μg/m2, το 2ο συνδυασμός ακετυλοπρομαζίνης-βουτορφανόλης σε δόσεις 0,05 mg/kg και 0,1 mg/kg αντίστοιχα, το 3ο δεξμεδετομιδίνη σε δόση 100 μg/m2 και το 4ο συνδυασμός ακετυλοπρομαζίνης-βουτορφανόλης σε δόσεις 0,1 mg/kg και o,2 mg/kg αντίστοιχα. Τα εν λόγω αντανακλαστικά, εξετάστηκαν σε κλινικά υγιείς σκύλους και σε σκύλους με θωρακοσφυϊκό σύνδρομο πριν και μετά τη χορήγηση των παραπάνω αναισθητικών πρωτοκόλλων. Διαπιστώθηκε ότι το αντανακλαστικό της επιγονατίδας επηρεάζεται από τη χορήγηση ηρέμησης λιγότερο από εκείνο της κάμψης και ότι μπορεί να θεωρείται αξιόπιστο όταν εξετάζεται υπό αυτές τις συνθήκες για την νευροανατομική εντόπιση της βλάβης στη θωρακοσφυϊκή μοίρα του νωτιαίου μυελού, σε ζώα που πάχουν από θωρακοσφυϊκό σύνδρομο.
description: Examination of spinal reflexes is fundamental for accurate neuroanatomical localization of the lesion. However, it is not always possible to perform it in uncooperative canine patients. The aim of the present study was to investigate the reliability of the patellar and withdrawl reflex when examined under sedation. Four different anaesthetic protocols were used: dexmedetomidine 180 μg/m2, acetylopromazine combined with butorphanol in o,o5 mg/kg and o,1 mg/kg respectively, dexmedetomidine 100 μg/m2 and acetylopromazine combined with butorphanol in o,1 mg/kg and o,2 mg/kg respectively. Reflexes were examined in healthy dogs and in canine patients presented with thoracolumbar syndrome, before and after the administration of sedation. It was concluded that patellar reflex is influenced less by sedation compared to withdrawl reflex and that the former can be considered reliable when examined under these circumstances for neuroanatomical localization of the disease in the thoracolumbar part of the spinal cord.

description: $\rm ^{83m}Kr$, with a short lifetime, is an ideal calibration source for liquid xenon or liquid argon detectors. The $\rm ^{83m}Kr$ isomer can be generated through the decay of $\rm ^{83} Rb$ isotope which is usually produced by proton beams bombarding natural krypton atoms. In this paper, we report a successful production of $\rm ^{83}Rb/^{83m}Kr$ with a proton beam energy of 3.4 MeV, and the first measurement of the production rate with such low energy proton beams. Another production attempt is performed using the newly available 20 MeV proton beam in China, and the measured production rate is consistent with previous measurements. The produced $\rm ^{83m}Kr$ source has been successfully injected into the PandaX-II liquid xenon detector, yielding enough statistics for detector calibration.

description: In this paper we first study some global properties of the energy functional on a non-reversible Finsler manifold. In particular we present a fully detailed proof of the Palais--Smale condition under the completeness of the Finsler metric. Moreover we define a Finsler metric of Randers type, which we call Fermat metric, associated to a conformally standard stationary spacetime. We shall study the influence of the Fermat metric on the causal properties of the spacetime, mainly the global hyperbolicity. Moreover we study the relations between the energy functional of the Fermat metric and the Fermat principle for the light rays in the spacetime. This allows us to obtain existence and multiplicity results for light rays, using the Finsler theory. Finally the case of timelike geodesics with fixed energy is considered.

description: Οι αποφάσεις που σχετίζονται με την αυτο-ρύθμιση της μάθησης είναι πολλές και περίπλοκες. Βασίζονται στις απαιτήσεις των γνωστικών έργων και σε ατομικά χαρακτηριστικά του μαθαίνοντας ατόμου, όπως η προηγούμενη γνώση, τα κίνητρα και το συναίσθημα. Οι αποφάσεις για την αυτο-ρύθμιση της μάθησης βασίζονται, επίσης, σε μεταμνημονικές εκτιμήσεις σε σχέση με την ευκολία, π.χ., απομνημόνευσης του υλικού προς μάθηση ή της επίλυσης ενός προβλήματος, και στην προσφορότητα των κατάλληλων στρατηγικών. Είναι σημαντικό, λοιπόν, να διερευνηθούν, πέρα από τα κίνητρα και τους στόχους των ατόμων, οι μηχανισμοί με τους οποίους λειτουργεί η μεταμνήμη και ειδικότερα οι μεταγνωστικές εμπειρίες που συνδέονται με την ευκολία ή δυσκολία της επίλυσης προβλημάτων (Efklides, 2011). Το γεγονός ότι τα άτομα μπορούν να διαφοροποιήσουν το νόημα των μεταγνωστικών τους εμπειριών και αυτό να επηρεάσει την επιλογή των στρατηγικών που θα χρησιμοποιήσουν ενισχύει την αποτελεσματικότερη απόδοση στη μάθηση. Με αυτό τον τρόπο τα άτομα αναπτύσσουν πολλαπλές στρατηγικές, έτσι ώστε να κατακτήσουν τη μάθηση (Brown, 1978. Frabricius & Schwanenflugel, 1994). Η έρευνα που ακολουθεί στόχο είχε να διερευνήσει παράγοντες που επηρεάζουν την ακρίβεια μεταγνωστικών εμπειριών όπως των κρίσεων ευκολίας ή δυσκολίας της μάθησης. Ειδικότερα, εξετάστηκαν παράγοντες όπως η αντιληπτική ευχέρεια, η αντικειμενική δυσκολία του έργου και οι επιδράσεις των οδηγιών του έργου, όπως το αν το έργο είναι εύκολο ή δύσκολο με βάση συγκριτική γνώση σχετικά με τις επιδόσεις άλλων στα υπό εξέταση έργα. Ένας επιπλέον παράγοντας που μελετήθηκε ήταν η γλωσσική διατύπωση των κρίσεων, αν δηλαδή είναι διατυπωμένη με όρους «ευκολίας» ή «δυσκολίας». Στη συνέχεια, θα αναφερθούν, πρώτον, τα εμπειρικά ευρήματα για τις κρίσεις μάθησης, για τις κρίσεις ευκολίας της μάθησης, που είναι είδος των κρίσεων μάθησης, και τις κρίσεις που αφορούν το αίσθημα δυσκολίας. Στόχος είναι να συνδυαστούν δύο διαφορετικές παραδόσεις έρευνας, αυτής για τις κρίσεις μάθησης και τις κρίσεις για την ευκολία μάθησης, από τη μια, και αυτής για το αίσθημα δυσκολίας. Στη συνέχεια, θα περιγραφεί η έρευνα που έγινε για τις κρίσεις ευκολίας/ δυσκολίας στην επίλυση προβλημάτων και θα ακολουθήσει η συζήτηση των αποτελεσμάτων.

description: We present some classical properties for non-abelian Yang-Mills theories that we extract directly from the Maxwell's equations of the theory. We write the equations of motion for the SU(3) Yang-Mills theory using the language of Maxwell's equations in both differential and integral forms. We show that vectorial gauge fields in this theory are non-fermionic sources for non-abelian electric and magnetic fields. These vectorial gauge fields are also responsible for the existence of magnetic monopoles. We build the continuity equation and the energy-momentum tensor for the non-abelian case.

description: The one dimensional Bose-Hubbard model at a unit filling factor is studied by means of a very high order symbolic perturbative expansion. Analytical expressions are derived for the ground state quantities such as energy per site, variance of on-site occupation, and different correlation functions. These findings are compared to numerics and good agreement is found in the Mott insulator phase. Our results provide analytical approximations to important observables in the Mott phase, and are also of direct relevance to future experiments with ultra cold atomic gases placed in optical lattices. We also discuss the symmetry of the Bose-Hubbard model associated with the sign change of the tunneling coupling.

description: As an important perceptual characteristic of the Human Visual System (HVS), the Just Noticeable Difference (JND) has been studied for decades with image and video processing (e.g., perceptual visual signal compression). However, there is little exploration on the existence of JND for the Deep Machine Vision (DMV), although the DMV has made great strides in many machine vision tasks. In this paper, we take an initial attempt, and demonstrate that the DMV has the JND, termed as the DMV-JND. We then propose a JND model for the image classification task in the DMV. It has been discovered that the DMV can tolerate distorted images with average PSNR of only 9.56dB (the lower the better), by generating JND via unsupervised learning with the proposed DMV-JND-NET. In particular, a semantic-guided redundancy assessment strategy is designed to restrain the magnitude and spatial distribution of the DMV-JND. Experimental results on image classification demonstrate that we successfully find the JND for deep machine vision. Our DMV-JND facilitates a possible direction for DMV-oriented image and video compression, watermarking, quality assessment, deep neural network security, and so on.

description: Links between two well known methods: methods of zero-range and non-overlapped (muffin-tin) potentials are discussed. Some difficulties of the method of zero-range potentials and its possible elimination are discussed. We argue that such advanced method of ZRP potential can be applied to realistic electron-molecular processes. The method reduces electron-molecule scattering to generalized eigenvalue problem for hermitian matrices and admit fast numerical scheme. A noteworthy feature of the method is direct possibility to calculate the wave functions (partial waves). The theory is applied to electron-uracil scattering. Partial phases and cross-sections at low energies are evaluated and plotted.

description: Advances in the motor imagery (MI)-based brain-computer interfaces (BCIs) allow control of several applications by decoding neurophysiological phenomena, which are usually recorded by electroencephalography (EEG) using a non-invasive technique. Despite great advances in MI-based BCI, EEG rhythms are specific to a subject and various changes over time. These issues point to significant challenges to enhance the classification performance, especially in a subject-independent manner. To overcome these challenges, we propose MIN2Net, a novel end-to-end multi-task learning to tackle this task. We integrate deep metric learning into a multi-task autoencoder to learn a compact and discriminative latent representation from EEG and perform classification simultaneously. This approach reduces the complexity in pre-processing, results in significant performance improvement on EEG classification. Experimental results in a subject-independent manner show that MIN2Net outperforms the state-of-the-art techniques, achieving an F1-score improvement of 6.72%, and 2.23% on the SMR-BCI, and OpenBMI datasets, respectively. We demonstrate that MIN2Net improves discriminative information in the latent representation. This study indicates the possibility and practicality of using this model to develop MI-based BCI applications for new users without the need for calibration.

description: The scope of this thesis was to investigate the seventh chapter of the Bankruptcy Code, entitled "Restructuring/Reorganization Plan" and consists of 25 articles which are intended to rescue the debtor´s business, its exploitation or distribution, while regulate his responsibility status even after the bankruptcy proceedings are over with. Specifically, (the thesis) investigated the purpose of the legislature, the legal nature of the reorganization plan, its contents and the steps to be taken prior to submission of the plan to the bankruptcy court for ratification. Moreover, the thesis analyzed the potentials of the acceptance or the rejection of the reorganization plan by the bankruptcy court and the consequences at either case, and also the probabilities of its cancellation, overthrow or abortion. Finally, the thesis examined the applicable in foreign laws "prepackaged/prenegotiated plans" and the chances of success of its implementation in the context of Greek law, and the general financial circumstances in the greek economy.
The design of a zero-effluent discharge system for Westcoast Energy inc.’s Fort Nelson Gas Plant
Creators: name: Bechtold, Jean-Philippe
Publisher: name: University of British Columbia
Year: 2009

description: This project was initiated by Westcoast Energy Inc. (Westcoast) to examine the feasibility of transforming their Fort Nelson Gas Plant (FNGP) into a zero-effluent discharge (ZED) facility. Water flow and water chemistry data were collected at the plant. The resulting data set was used to identify water leaks in the existing distribution network, as well as to identify methods of optimizing water use at this facility. Designs for implementing a Z ED protocol at the FNGP were then developed and subsequently evaluated with a computer simulator. A total of 18 Z E D models were constructed using reverse osmosis (RO) membranes, nanofilters and other Z ED technology. The final disposal mechanism in 10 of the 18 scenarios was a brine concentrator - spray dryer (BCS) assembly, which reduced all remaining wastewater into a solid waste. In the other 8 Z ED designs, final concentrates were disposed of in a deep well. The best deep well configuration was a 1-stage RO filter; the necessary equipment, excluding the deep well, would cost an estimated $101 700 US dollars. The best BCS scenarios were a 1-stage R O and a BCS-only models; they would cost around $1.61 and $1.79 million US dollars, respectively. A step by step approach by which the FNGP can be transformed into a Z ED facility is detailed in Chapter 8.0 of this report. While it is possible to implement a Z ED program at the FNGP, there are consequences to this course of action which need to be considered. The most important is final waste management. Regardless of whether a deep well or a BCS unit is used, either system will have to be built and operated in such a way that the final waste products produced by the Z ED treatment train do not migrate off-site, as this action would violate the Z ED principle. Once a Z E D program is initiated, wastewater and/or waste solids produced at the FNGP will no longer disappear with the FNR; they will remain on-site indefinitely.

description: The main physics goals of a high luminosity e+e- flavor factory are discussed, including the possibilities to perform detailed studies of the CKM mechanism of quark mixing, and constrain virtual Higgs and non-standard model particle contributions to the dynamics of rare B_u,d,s decays. The large samples of $D$ mesons and tau leptons produced at a flavor factory will result in improved sensitivities on D mixing and lepton flavor violation searches, respectively. One can also test fundamental concepts such as lepton universality to much greater precision than existing constraints and improve the precision on tests of CPT from B meson decays. Recent developments in accelerator physics have demonstrated the feasibility to build an accelerator that can achieve luminosities of O(10^36) cm^-2 s^-1.

description: Nb-Ru is a high temperature shape memory alloy that undergoes a Martensitic transformation from a parent cubic b-phase into a tetragonal b' phase at TM 900 C. Measurements of the phonon dispersion curves show that the [110]-TA2 phonon branch, corresponding in the q=0 limit to the elastic constant C'=1/2(C11-C12) has an anomalous temperature dependence. Nearly the entire branch softens with decreasing temperature as TM is approached. The temperature dependence of the low-q phonon energies suggests that the elastic constants would approach 0 as T approaches TM, indicating a second order transition. No additional lattice modulation is observed in the cubic phase.

description: It is well-known that every 6-dimensional strictly nearly Kähler manifold $(M,g,J)$ is Einstein with positive scalar curvature $scal>0$. Moreover, one can show that the space $E$ of co-closed primitive (1,1)-forms on $M$ is stable under the Laplace operator $Δ$. Let $E(a)$ denote the $a$-eigenspace of the restriction of $Δ$ to $E$. If $M$ is compact, we prove that the moduli space of infinitesimal Einstein deformations of the nearly Kähler metric $g$ is naturally isomorphic to the direct sum $E(scal/15)\oplus E(scal/5)\oplus E(2scal/5)$. It is known that the last summand is itself isomorphic with the moduli space of infinitesimal nearly Kähler deformations.

description: The wave propagation in random medium plays a critical role in optics and quantum physics. Multiple scattering of coherent wave in a random medium determines the transport procedure. Brownian motions of the scatterers perturb each propagation trajectory and form dynamic speckle patterns in the backscattered direction. In this study, we applied the random matrix theory (RMT) to investigate the eigenvalue density of the backscattered intensity matrix. We find that the dynamic speckle patterns can be utilized to decouple the singly and multiply backscattered components. The Wishart random matrix of multiple scattering component is well described by the Marcenko-Pastur law, while the single scattering part has low-rank characteristic. We therefore propose a strategy for estimating the first and the second order moments of single and multiple scattering components, respectively, based on the Marcenko-Pastur law and trace analysis. Electric field Monte Carlo simulation and in-vivo experiments demonstrate its potential applications in hidden absorbing object detection and in-vivo blood flow imaging. Our method can be applied to other coherent domain elastic scattering phenomenon for wide-filed propagation of microwave, ultrasound and etc.

description: We provide a simple derivation of the extremal values of the superpotential in massive vacua of N=1* SYM, making use of the required modular weight for the central charge of BPS walls interpolating between these vacua. This modular weight descends from the action of S-duality on the N=4 superalgebra which in turn is inherited from its classical action on the dyon spectrum. We show that this kinematic information, combined with minimal knowledge of the weak coupling asymptotics, is sufficient to determine the exact vacuum superpotentials in terms of Eisenstein series.

description: Σκοπός της παρούσας εργασίας είναι η παρουσίαση και η μελέτη των εκκλησιαστικών ΜΜΕ στην Ελλάδα. Εξετάζεται τόσο το τι ισχύει σε νομικό επίπεδο σχετικά με τα εκκλησιαστικά ΜΜΕ στην Ελλάδα όσο και τα χαρακτηριστικά ενδεικτικών εκκλησιαστικών ΜΜΕ (τηλεοπτικών, ραδιοφωνικών, ιστολογίων και μέσων κοινωνικής δικτύωσης). Τα τελευταία χαρακτηρίζονται από την προσπάθεια των διαχειριστών τους να αξιοποιήσουν τα αποτελέσματα της τεχνολογικής ανάπτυξης στο χώρο των ΜΜΕ και να απευθυνθούν σε ένα κοινό που ξέρει να χειρίζεται τα Νέα Μέσα. Όσον αφορά τους κανονισμούς και τις εγκυκλίους της Εκκλησίας της Ελλάδος σχετικά με τα ΜΜΕ, χαρακτηρίζονται από την προσπάθεια αντιμετώπισης των καινούργιων δεδομένων που αφορούν την προβολή τόσο της Θείας Λατρείας καθώς και γενικότερα της εικόνας της Εκκλησίας στην τηλεόραση και το ραδιόφωνο.
description: The aim of the present dissertation is the presentation and the study of the church Mass Media in Greece. We examined the relevant legal text for the Greek Mass Media as well as the characteristics of indicative church Mass Media (television and radio stations, blogs and social networking sites). We found that the under examination Mass Media are characterized by the effort of their administrators to take advantage of the technological evolution in the domain of Mass media as well as to communicate with a public already acquainted with New Media. Concerning the circulars and the regulations of the Greek Church about Mass Media, our data shows an effort of managing the new data concerning the broadcast of the religious service and, generally, the image of the Greek Church on television or radio.
Flexural toughness of fibre reinforced concrete

description: Fibres are added to concrete to improve energy absorption and apparent ductility. Flexural toughness, derived from the load-deflection response, is often used to describe these improvements. There are, however, a number of uncertainties regarding how FRC flexural toughness should be measured, interpreted, or used. Various flexural toughness test methods have been developed in different countries. ASTM-C1018, JSCE-SF4, and NBP No. 7 are three of the most commonly used test methods. Based on a large number of experiments, the present work studies effects of testing and material variables on both the load-deflection response and the flexural toughness of FRC, investigates the reproducibility of the flexural toughness test methods of FRC (both within-laboratory and between laboratories), discusses difficulties in toughness evaluation, defines various flexural toughness parameters, assesses relative advantages and disadvantages of different methods of characterizing toughness, and develops recommendations for a more suitable procedure for FRC flexural toughness evaluation. It has been found the load-deflection response of FRC is an experimental property and so are the flexural toughness parameters derived from the response. They depend not only on material variables but also on testing factors. Of the various testing variables, the deflection measuring system, the loading system, and specimen size/geometry are the three most important factors; while amongst the various material variables, fibre content and fibre type/profile are the most important. The major difficulties in measuring the load-deflection response, caused by either extraneous deformations, first crack determination, or instability, has much more significant effects on ASTM toughness parameters than on JSCE toughness parameters. For this reason, ASTM parameters may not be particularly sensitive in distinguishing either amongst different fibre contents for SFRC and PFRC or between SFRC and PFRC with similar low fibre contents. JSCE parameters are more sensitive in this regard. On the basis of assessing the reliability and efficiency of various toughness parameters, both a suite of toughness parameters and toughness performance levels are proposed. The full suite of toughness parameters provide more complete useful information, while Toughness Performance Levels offer sufficient information for toughness evaluation.

description: Context: Software startups develop innovative, software-intensive products. Given the uncertainty associated with such an innovative context, experimentation is a valuable approach for these companies, especially in the early stages of the development, when implementing unnecessary features represents a higher risk for companies' survival. Nevertheless, researchers have argued that the lack of clearly defined practices led to limited adoption of experimentation. In this regard, the first step is to define the hypotheses based on which teams will create experiments. Objective: We aim to develop a systematic technique to identify hypotheses for early-stage software startups. Methods: We followed a Design Science approach consisted of three cycles in the construction phase, that involved seven startups in total, and an evaluation of the final artifact within three startups. Results: We developed the HyMap, a hypotheses elicitation technique based on cognitive mapping. It consists of a visual language to depict a cognitive map representing the founder's understanding of the product, and a process to elicit this map consisted of a series of questions the founder must answer. Our evaluation showed that the artifacts are clear, easy to use, and useful leading to hypotheses and facilitating founders to visualize their idea. Conclusion: Our study contributes to both descriptive and prescriptive bodies of knowledge. Regarding the first, it provides a better understanding of the guidance founders use to develop their startups and, for the latter, a technique to identify hypotheses in early-stage software startups.

description: Αντικείμενο της παρούσας διπλωματικής εργασίας ήταν η υλοποίηση ενός προσομοιωτικού εργαλείου οπτικών επικοινωνιακών συστημάτων. Για το σκοπό αυτό χρησιμοποιήθηκε το λογισμικό πακέτο Simulink που είναι ενσωματωμένο στο Matlab από την έκδοση 7.0 και μετά. Τα οπτικά συστήματα που μοντελοποιήθηκαν ήταν ένα laser, τρεις οπτικοί διαμορφωτές (ΟΟΚ, DPSK, DQPSK), ένας EDFA ενισχυτής και μια μονότροπη οπτική ίνα όπου ελήφθησαν υπ’ όψη τα εξής φαινόμενα: εξασθένηση, διασπορά και αυτοδιαμόρφωση φάσης (SPM). Μετά την υλοποίηση των μοντέλων ακολούθησε η προσομοίωσή τους για επαλήθευση της ορθής λειτουργίας τους.
description: The aim of this thesis was the development of a simulator for optical fiber communication systems. The realization of this objective was achieved using Simulink, a block diagram environment integrated with Matlab since version 7.0. Particularly, the optical systems that we modeled were one laser, three optical modulators (OOK, DPSK, DQPSK), an EDFA amplifier and a single mode optical fiber (SMF) taking into account the following phenomena: attenuation, group velocity dispersion (GVD) and self-phase modulation (SPM). After modeling the above systems, we simulated them in order to verify their proper performance.

description: We introduce a class of continuous maps f of a compact metric space I admitting inducing schemes and describe the tower constructions associated with them. We then establish a thermodynamical formalism, i.e., describe a class of real-valued potential functions ϕon I which admit unique equilibrium measures μ_ϕminimizing the free energy for a certain class of measures. We also describe ergodic properties of equilibrium measures including decay of correlation and the Central Limit Theorem. Our results apply in particular to some one-dimensional unimodal and multimodal maps as well as to multidimensional nonuniformly hyperbolic maps admitting Young's tower. Examples of potential functions to which our theory applies include ϕ_t=-t\log|df| with t\in(t_0, t_1) for some t_0<1

description: Raman scattering experiments on CdCr2S4 single crystals show pronounced anomalies in intensity and frequency of optical phonon modes with an onset temperature T*=130 K that coincides with the regime of giant magnetocapacitive effects. A loss of inversion symmetry and Cr off-centering are deduced from the observation of longitudinal optical and formerly infrared active modes for T

description: Comprehensive benchmarking of clustering algorithms is rendered difficult by two key factors: (i)~the elusiveness of a unique mathematical definition of this unsupervised learning approach and (ii)~dependencies between the generating models or clustering criteria adopted by some clustering algorithms and indices for internal cluster validation. Consequently, there is no consensus regarding the best practice for rigorous benchmarking, and whether this is possible at all outside the context of a given application. Here, we argue that synthetic datasets must continue to play an important role in the evaluation of clustering algorithms, but that this necessitates constructing benchmarks that appropriately cover the diverse set of properties that impact clustering algorithm performance. Through our framework, HAWKS, we demonstrate the important role evolutionary algorithms play to support flexible generation of such benchmarks, allowing simple modification and extension. We illustrate two possible uses of our framework: (i)~the evolution of benchmark data consistent with a set of hand-derived properties and (ii)~the generation of datasets that tease out performance differences between a given pair of algorithms. Our work has implications for the design of clustering benchmarks that sufficiently challenge a broad range of algorithms, and for furthering insight into the strengths and weaknesses of specific approaches.

Online Deterministic Annealing for Classification and Clustering

Subjects: subject: Machine Learning (cs.LG)

description: Inherent in virtually every iterative machine learning algorithm is the problem of hyper-parameter tuning, which includes three major design parameters: (a) the complexity of the model, e.g., the number of neurons in a neural network, (b) the initial conditions, which heavily affect the behavior of the algorithm, and (c) the dissimilarity measure used to quantify its performance. We introduce an online prototype-based learning algorithm that can be viewed as a progressively growing competitive-learning neural network architecture for classification and clustering. The learning rule of the proposed approach is formulated as an online gradient-free stochastic approximation algorithm that solves a sequence of appropriately defined optimization problems, simulating an annealing process. The annealing nature of the algorithm contributes to avoiding poor local minima, offers robustness with respect to the initial conditions, and provides a means to progressively increase the complexity of the learning model, through an intuitive bifurcation phenomenon. The proposed approach is interpretable, requires minimal hyper-parameter tuning, and allows online control over the performance-complexity trade-off. Finally, we show that Bregman divergences appear naturally as a family of dissimilarity measures that play a central role in both the performance and the computational complexity of the learning algorithm.

Spontaneous Lorentz Breaking at High Energies

description: Theories that spontaneously break Lorentz invariance also violate diffeomorphism symmetries, implying the existence of extra degrees of freedom and modifications of gravity. In the minimal model (``ghost condensation'') with only a single extra degree of freedom at low energies, the scale of Lorentz violation cannot be larger than about M ~ 100GeV due to an infrared instability in the gravity sector. We show that Lorentz symmetry can be broken at much higher scales in a non-minimal theory with additional degrees of freedom, in particular if Lorentz symmetry is broken by the vacuum expectation value of a vector field. This theory can be constructed by gauging ghost condensation, giving a systematic effective field theory description that allows us to estimate the size of all physical effects. We show that nonlinear effects become important for gravitational fields with strength \sqrtΦ > g, where g is the gauge coupling, and we argue that the nonlinear dynamics is free from singularities. We then analyze the phenomenology of the model, including nonlinear dynamics and velocity-dependent effects. The strongest bounds on the gravitational sector come from either black hole accretion or direction-dependent gravitational forces, and imply that the scale of spontaneous Lorentz breaking is M < Min(10^{12}GeV, g^2 10^{15}GeV). If the Lorentz breaking sector couples directly to matter, there is a spin-dependent inverse-square law force, which has a different angular dependence from the force mediated by the ghost condensate, providing a distinctive signature for this class of models.

description: Στην παρούσα διπλωματική εργασία περιγράφεται η διατύπωση της εντροπίας του Tsallis στα πλαίσια της μη εκτατικής στατιστικής θερμοδυναμικής και η θεμελιώδης εργασία του Hill για την θερμοδυναμική των μικρών συστημάτων (nanothermodynamics). Η σύνδεση μεταξύ των δύο αυτών κλάδων της θερμοδυναμικής έχει γίνει μέσω της κατανομής πιθανοτήτων ισορροπίας του μεγέθους νανοκρυστάλλων πυριτίου οι οποίοι αποτελούν ένα αντιπροσωπευτικό παράδειγμα της τελείως ανοικτής συλλογής. Με χρήση της μεθόδου LPCVD (low pressure chemical vapor deposition) αναπτύχθηκαν υπέρλεπτα υμένια νανοκρυστάλλων πυριτίου, με μεταβλητό πάχος από 5 έως 30 nm, πάνω σε υπόστρωμα quartz. Μελέτη με cross-sectional transmission electron microscopy (TEM) έδειξε ότι τα υμένια παρουσίασαν κολωνοειδή ανάπτυξη δηλαδή η τρίτη διάσταση των νανοκρυστάλλων, κάθετη στη διεπιφάνεια Si/SiO2, ήταν περίπου ίση με το πάχος του υμενίου ενώ η διάμετρος των νανοκρυστάλλων (lateral size) καθορίστηκε από τα αρχικά στάδια της ανάπτυξης και δεν επηρεάστηκε από το πάχος των υμενίων. Εικόνες της κάτοψης (plane view) των νανοκρυστάλλων έδειξαν ότι η κατανομή του πλευρικού μεγέθους (διαμέτρου) τους παρουσιάζει μέγιστο σε όλα τα υμένια.
description: The aim of the present thesis was the study of the entropy formulation of Tsallis in the context of non-extensive statistical thermodynamics and the fundamental works of Hill on thermodynamics of small systems (nanothermodynamics). Α connection between these two branches of thermodynamics has been made through equilibrium probability distribution of the lateral size of Si nanocrystals which are an example of the completely open ensemble. Ultra-thin nanocrystalline silicon films with varying thickness from 5 to 30nm were grown on quartz by low pressure chemical vapor deposition (LPCVD) of Si. Observations on cross-sectional transmission electron microscopy (TEM) specimens revealed that the films had a columnar growth. The observed columnar growth gives the possibility to obtain two-dimensional nanocrystal arrays on quartz with well-defined size in the z-direction.
