Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The present work employs the Linder parametrization of a constant growth index \cite{linder/index} to investigate the evolution of growth rate of clustering and the dissipation of configurational entropy in some of the most widely studied Chaplygin gas models, such as the generalized Chaplygin gas and the modified Chaplygin gas. The model parameters of the Chaplygin gas models are found to play a vital role in the evolution of growth rate, dark energy density parameter, EoS parameter, and configurational entropy. Furthermore, the work communicates the rate of change of configurational entropy to attain a minimum which depend solely on the choice of model parameters and that there exist suitable parameter combinations giving rise to a viable dissipation of configurational entropy, and therefore certifying its time derivative to hit a minimum at a scale factor which complies with the current observational constraints on the redshift of transition from a dust to an accelerated Universe and thereby making Chaplygin gas models a viable candidate for dark energy.

description: Using the Millennium N-body simulation we explore how the shape and angular momentum of galaxy dark matter haloes surrounding the largest cosmological voids are oriented. We find that the major and intermediate axes of the haloes tend to lie parallel to the surface of the voids, whereas the minor axis points preferentially in the radial direction. We have quantified the strength of these alignments at different radial distances from the void centres. The effect of these orientations is still detected at distances as large as 2.2 R_void from the void centre. Taking a subsample of haloes expected to contain disc-dominated galaxies at their centres we detect, at the 99.9% confidence level, a signal that the angular momentum of those haloes tends to lie parallel to the surface of the voids. Contrary to the alignments of the inertia axes, this signal is only detected in shells at the void surface (1

description: Le changement climatique pose une émergente et une sévère menace pour les coraux. Cette étude est focalisée sur la dépendance des facteurs climatiques sur le rythme de croissance des coraux de la partie marine de l’Aire Protégée Antrema au Nord-Ouest de Madagascar. Les paramètres de  05 colonies de coraux massifs Porites sp collectés à Ambatonankoay ont été obtenus par analyse des bandes de croissance des clichés radiographiques X des plaquettes des coraux et les paramètres de croissance des coraux ainsi obtenues ont été comparés aux SST et à la pluviométrie du site. Le taux de croissance moyenne des coraux varie de 0.8596±0.3851 et de 0.9166±0.3495 cm.an-1.  La densité réelle moyenne de squelette des coraux correspond à 1.75g.cm-3. Cette densité moyenne varie de 0.54 à 1.96 g.cm-3. Le taux de calcification est compris entre 0.19 g.cm-3 et 3.65 g.cm-3. La relation entre les données climatiques et les paramètres de croissance des coraux n’est pas nulle. 02 colonies sur les 05 ont montré une relation significative avec la SST (R2 =0,1729, p = 0,0179 ; R2 = 0,1543, p = 0,02617) et toutes les 05 colonies ont une relation non significative avec la pluviométrie. La relation est forte avec la SST alors qu’elle est faible avec la pluviométrie.

description: We introduce a method for the coherent acceleration of atoms trapped in an optical lattice, using the well-known model for stimulated Raman adiabatic passage (STIRAP). Specifically, we show that small harmonic modulations of the optical lattice amplitude, with frequencies tuned to the eigenvalue spacings of three "unperturbed" eigenstates, reveals a three-state STIRAP subsystem. We use this model to realize an experimentally achievable method for transferring trapped atoms from stationary to motional eigenstates.

description: Since the end of the 20th century, associations and cooperatives have been perceived by a growing part of the population as actors capable of dealing with societal problems and responding to the aspirations of inhabitants. Civil society, public authorities, universities and the media saw them as an essential foundation for the necessary renewal of economic life. This trend has placed the social economy in a unique position to face three essential challenges: the political challenge, which has invited it to move from solving social problems to drawing up a development policy; the technological challenge, which has led it to manage the new working conditions and the new forms of social interaction induced by the development of new technologies; and finally, the environmental challenge, which encourages it to become an economy that is not only social but also ecological, able to develop without increasing its impact on the environment.

Cette promotion a placé l'économie sociale et solidaire (ESS) de façon singulière face à trois défis essentiels: le défi politique, qui l’a invitée à passer de la résolution des problèmes sociaux à la conception d’une politique de développement; le défi technologique, qui l’a amenée à gérer le nouveau rapport au travail et les nouvelles sociabilités induits par l’essor des nouvelles technologies; le défi environnemental enfin, qui l’incite à devenir une économie non seulement sociale mais aussi écologique, capable de se développer sans accroître son impact sur l’environnement.

Στην παρούσα εργασία, μελετήθηκε ο βαθμός βιομετατροπής των παραπάνω μη πτητικών πρόδρομων ενώσεων σε 3SH και η επίδραση τους στο άρωμα του οίνου. Δεν παρατηρήθηκε αναλογία ανάμεσα στη συγκέντρωση της Cys-3SH στο γλεύκος και στη συγκέντρωση της 3SH στον οίνο. Ο βαθμός βιομετατροπής δεν βρέθηκε να είναι υψηλότερος από 10%, ενώ ήταν ακόμη χαμηλότερος στην περίπτωση της Gsh-3SH. Η προέλευση των πρόδρομων ενώσεων επιδρά στο ποσοστό βιομετατροπής τους προς 3SH, το οποίο βρέθηκε να είναι υψηλότερο όταν το παράγωγο ήταν προϊόν βιολογικής σύνθεσης. Η παραμονή του γλεύκους σε επαφή με τις γλευκολάσπες του κατά την οινοποίηση δεν τροποποίησε σημαντικά το βαθμό βιομετατροπής. Επιπλέον για τη δεδομένη χρονιά (2012) και τα γλεύκη που μελετήθηκαν δεν παρατηρήθηκε το φαινόμενο που αποκαλείται “ effet de bourbe”.
description: The varietal aroma of Sauvignon blanc wines is impacted from volatile thiols, compounds released during alcoholic fermentation. Their non volatile precursors present in grape juice are S-conjugates of cysteine and glutathione. This study is emphasized in the biotransformation percent of these precursors in the volatile thiol 3SH and their final impact in the liberation of 3SH in the wine. For the cysteinylated precursor there isn’t proportionality between the precursor’s amount and the volatile thiol liberated in the wine. The transformation rate doesn’t exceed 10% while it is even lower for the glutathionylated precursor. The origin of the precursor plays an important role. The results for the biologically synthesized Cys-3SH showed a higher biotransformation rate compared to the chemical. The study of prefermentative treatments stabulation and presence of turbid during vinification showed no important influence in the biotransformation percent. Additionally, we can conclude that this year and for the studied musts isn’t observed a “bourbe effect”.

description: Time-series CCD photometric observations of the intermediate-age open cluster NGC 2099 were performed to search for variable stars. We also carried out BV photometry to study physical properties of variables in the cluster. Using V-band time-series data, we carefully examined light variations of about 12,000 stars in the range of 10 < V < 22 mag. A total of 24 variable stars have been identified; seven stars are previously known variables and 17 stars are newly identified. On the basis of observational properties such as light curve shape, period, and amplitude, we classified the new variable stars as nine delta Scuti-type pulsating stars, seven eclipsing binaries, and one peculiar variable star. Judging from the position of delta Scuti-type stars in the color-magnitude diagram, only two stars are likely to have the cluster membership. One new variable KV10 shows peculiar light variations with a delta Scuti-type short period of about 0.044 day as well as a long period of 0.417 day.

description: Existing super-resolution methods of optical imaging hold a solid place as an application in natural sciences, but many new developments allow for beating the diffraction limit in a more subtle way. One of the recently explored strategies to fully exploit information already present in the field is to perform a quantum-inspired tailored measurements. Here we exploit the full spectral information of the optical field in order to beat the Rayleigh limit in spectroscopy. We employ an optical quantum memory with spin-wave storage and an embedded processing capability to implement a time-inversion interferometer for input light, projecting the optical field in the symmetric-antisymmetric mode basis. Our tailored measurement achieves a resolution of 15 kHz and requires 20 times less photons than a corresponding Rayleigh-limited conventional method. We demonstrate the advantage of our technique over both conventional spectroscopy and heterodyne measurements, showing potential for application in distinguishing ultra-narrowband emitters, optical communication channels, or signals transduced from lower-frequency domains.

description: Across machine learning, the use of curricula has shown strong empirical potential to improve learning from data by avoiding local optima of training objectives. For reinforcement learning (RL), curricula are especially interesting, as the underlying optimization has a strong tendency to get stuck in local optima due to the exploration-exploitation trade-off. Recently, a number of approaches for an automatic generation of curricula for RL have been shown to increase performance while requiring less expert knowledge compared to manually designed curricula. However, these approaches are seldomly investigated from a theoretical perspective, preventing a deeper understanding of their mechanics. In this paper, we present an approach for automated curriculum generation in RL with a clear theoretical underpinning. More precisely, we formalize the well-known self-paced learning paradigm as inducing a distribution over training tasks, which trades off between task complexity and the objective to match a desired task distribution. Experiments show that training on this induced distribution helps to avoid poor local optima across RL algorithms in different tasks with uninformative rewards and challenging exploration requirements.
Camerata

Publisher: name: University of British Columbia
Year: 2009

description: This thesis consists of an original composition and an analysis of it. Scored for a small orchestra, the Camerata is approximately 16 minutes in length. The analysis deals with general matters of structure as well as details of harmonic organization that play a specific and prominent role in this work. The piece is to be perceived in four integrated sections. Each section has its own characteristics. However, the sequence from one section to another is functional, so that the piece would not work if the sequence of sections were arranged differently. Section B develops the thematic material of section A. Section C is an outgrowth of section B because of the exchange of the dynamic and static aspects pertaining to harmony and melody. Moreover, as a unifying element, these two central sections show tonal tendencies. Section D rounds off the piece with a concealed texturally decreasing formal design, which balances the crescendo and texturally increasing overall shape of the first section.
Nonconvex matrix and tensor recovery with applications in machine learning
Creators: name: Ghassemi, Mohsen
Publisher: name: No Publisher Supplied
Year: 2021

description: This thesis focuses on some fundamental problems in machine learning that are posed as nonconvex matrix factorizations. More specifically we investigate theoretical and algorithmic aspects of the following problems: i) inductive matrix completion (IMC), ii) structured dictionary learning (DL) from tensor data, iii) tensor linear regression and iv) principal component analysis (PCA). The theoretical contributions of this thesis include providing recovery guarantees for IMC and structured DL by characterizing the local minima and other geometric properties of these problems. The recovery results are stated in terms of upper bounds on the number of observations required to recover the true matrix (dictionary in the case of DL) underlying the data. Another major theoretical contribution of this work is providing fundamental limits on the performance of tensor linear regression solvers by deriving a lower bound on the worst case mean squared error of any estimator. On the algorithmic side, this thesis proposes novel online and batch algorithms for solving structured dictionary learning problem as well as a novel multi-stage accelerated stochastic PCA algorithm that achieves near optimal results.

description: We show that the parameter space for F-term inflation which predict the formation of cosmic strings is larger than previously estimated. Firstly, because realistic embeddings in GUT theories alter the standard scenerio, making the inflationary potential less steep. Secondly, the strings which form at the end of inflation are not necessarily topologically stable down to low scales. In shifted and smooth inflation strings do not form at all. We also discuss D-term inflation; here the possibilities are much more limited to enlargen paramer space.

Experimental and numerical simulation of charge motion in internal combustion engines

Publisher: name: University of British Columbia
Year: 2009

description: A combined study based on Laser Doppler velocimetry measurements and numerical simulation was used to investigate the effects of piston-bowl geometry and intake swirl level on the structure and evolution of the flow field near the top dead centre position of an internal combustion engine. The University of British Columbia Rapid Intake and Compression Machine (UBCRICM), was used for the experimental studies, while numerical calculations were performed with the KIVA-Il code. The KIVA-Il code is an incylinder fluid dynamics flow computer program, incorporating the following submodels; spray dynamics, species transport, mixing, chemical reactions and heat release rate. The effects of turbulence are represented by either the k-e or the subgrid scale (SGS) turbulence models. The k-e turbulence model option was used in the present study. The results of this study show that high-shear regions and the consequent turbulence production occurred near the bowl entrance around top dead centre of compression. These regions were created before top dead centre in both chambers by the interaction of swirl and squish. The flow parameters (mean radial and tangential velocities and turbulence intensity) resulting from the re-entrant bowl configuration were found to be consistently higher than those generated by the bowl-in-piston arrangement. The com putational results were compared to the experimental data. A very good agreement was obtained between predicted and measured mean radial and tangential velocity distribu tions. The numerical code was found t under estimate the measured turbulence intensity values in both chamber designs, however, a reasonable level of agreement was obtained with both chamber configurations. This study also highlighted the importance of accurately specifying the initial and boundary conditions. It was found that the very impressive level of agreement between measured and computed results was largely due to the fact that the initial and boundary conditions were accurately modelled to mimic actual experimental conditions. The investigation of the evolution of certain flow and turbulence quantities which could not be obtained experimentally was also undertaken with the KIVA-Il code. A comprehensive discussion of these flow quantities was presented and the various ways they are likely to affect engine performance in terms of combustion were highlighted.

description: We study double Hurwitz numbers in genus zero counting the number of covers $\CP^1\to\CP^1$ with two branching points with a given branching behavior. By the recent result due to Goulden, Jackson and Vakil, these numbers are piecewise polynomials in the multiplicities of the preimages of the branching points. We describe the partition of the parameter space into polynomiality domains, called chambers, and provide an expression for the difference of two such polynomials for two neighboring chambers. Besides, we provide an explicit formula for the polynomial in a certain chamber called totally negative, which enables us to calculate double Hurwitz numbers in any given chamber as the polynomial for the totally negative chamber plus the sum of the differences between the neighboring polynomials along a path connecting the totally negative chamber with the given one.

description: The s-enhanced and very metal-poor star CS 30322-023 shows a puzzling abundance pattern of the neutron-capture elements, i.e. several neutron-capture elements such as Ba, Pb etc. show enhancement, but other neutron-capture elements such as Sr, Eu etc. exhibit deficient with respect to iron. The study to this sample star could make people gain a better understanding of s- and r-process nucleosynthesis at low metallicity. Using a parametric model, we find that the abundance pattern of the neutron-capture elements could be best explained by a star that was polluted by an AGB star and the CS 30322-023 binary system formed in a molecular cloud which had never been polluted by r-process material. The lack of r-process material also indicates that the AGB companion cannot have undergone a type-1.5 supernova, and thus must have had an initial mass below 4.0M$_\odot$, while the strong N overabundance and the absence of a strong C overabundance indicate that the companion's initial mass was larger than 2.0M$_\odot$. The smaller s-process component coefficient of this star illustrates that there is less accreted material of this star from the AGB companion, and the sample star should be formed in the binary system with larger initial orbital separation where the accretion-induced collapse (AIC) mechanism can not work.

description: As a new degree of freedom for optical manipulation, recently spatiotemporal optical vortices (STOVs) carrying transverse orbital angular momentums have been experimentally demonstrated with pulse shapers. Here a spatiotemporal differentiator is proposed to generate STOVs with transverse orbital angular momentum. In order to create phase singularity in the spatiotemporal domain, the spatiotemporal differentiator is designed by breaking spatial mirror symmetry. In contrast to pulse shapers, the device proposed here is a simple one-dimensional periodic nanostructure and thus it is much more compact. For a normal incident pulse, the differentiator generates a transmitted STOV pulse with transverse orbital angular momentum. Furthermore, the interference of the generated STOVs can be used to detect the sharp changes of pulse envelopes, in both spatial and temporal dimensions.

Τα δεδομένα συγκεντρώθηκαν από 32 Συνεταιρισμούς απ’ όλη την Ελλάδα με τη βοήθεια δομημένου ερωτηματολογίου, επεξεργάστηκαν με το πρόγραμμα SPSS και αξιολογήθηκαν με βάση τις στρατηγικές του Porter (στρατηγική ηγεσίας κόστους, διαφοροποίησης, εστίασης). Τα αποτελέσματα δείχνουν ότι οι συνεταιρισμοί χρησιμοποιούν κυρίως τη στρατηγική ηγεσίας κόστους και τη στρατηγική της διαφοροποίησης στην προσπάθεια τους να αυξήσουν το μερίδιο αγοράς τους. Παράλληλα γίνονται ενέργειες, ώστε να βελτιώσουν τα προϊόντα τους με στόχο αφενός να γίνουν γνωστά σε μεγαλύτερες αγορές και να αυξήσουν τις πωλήσεις τους και αφετέρου να ικανοποιήσουν σε μεγαλύτερο βαθμό τις απαιτήσεις των πελατών τους. Ιδιαίτερα επίκαιρη κρίνεται η επέκταση της έρευνας στο σύνολο των Συνεταιρισμών της Ελλάδας λόγω της αναδιάρθρωσής τους που προωθείται αυτή την περίοδο.
description: The main purpose of this paper is to examine the strategies used by the Cooperatives in Greece to achieve competitive advantages. The data were collected from 32 Cooperatives, using a structured questionnaire, elaborated by the SPSS program and evaluated based on Porter’s strategies (cost leadership strategy, differentiation, focus strategy). The results show that cooperatives mainly use cost leadership strategy and differentiation strategy in an effort to increase their market share. At the same time, cooperatives are making efforts to improve product quality in order to arrive in greater and more demanding markets. Τhe expansion of the study is very timely due to the Government efforts for cooperatives restructuring.

description: Το περιεχόμενο αυτής της διπλωματικής εργασίας στηρίχθηκε στις σημειώσεις του Adam Van Tuyl με τίτλο “Ιδεώδη Ακμών και Κορυφών στα πλαίσια του θερινού σχολείου CIEM, Castro Urdiales (Cantabria), στην Ισπανία τον Ιούνιο του 2011. Στη παρούσα εργασία δοθέντος ενός πεπερασμένου γραφήματος G κατασκευάσουμε δυο μονωνυμικά ιδεώδη, το ιδεώδες ακμών και το ιδεώδες κορυφών του G και μελετούμε τις ιδιότητες τους. Μελετούμε τον χρωματικό αριθμό ενός γραφήματος και δείχνουμε οτι ο αριθμός αυτός υπολογίζεται αλγεβρικά από το ιδεώδες κορυφών. Στη συνέχεια παρουσιάζουμε το Βασικό Θεώρημα της Διπλωματικής, το Θεώρημα του Froberg το οποίο λέει ότι κάθε γράφημα είναι χορδικό αν και μόνον αν το ιδεώδες ακμών του γραφήματος έχει γραμμική επίλυση. Επιπλέον μελετούμε τις αναλύσεις των δυνάμεων των ιδεωδών κορυφών ενός γραφήματος, δείχνουμε ότι κάποια από τα προσαρτημένα ιδεώδη των δυνάμεων αυτών αντιστοιχούν σε χρωματικές πληροφορίες για το γράφημα και στη συνέχεια στρέφουμε τη προσοχή μας στην ανάγωγη ανάλυση των δυνάμεων αυτών.
description: The content of this thesis was based on notes of Adam Van Tuyl entitled "Ideals Edge and Peak within the summer school CIEM, Castro Urdiales (Cantabria), Spain in June 2011. In the present work given a finite graph G construct two monomial ideals, the edge ideal and the cover ideal of G and studying their properties. We study the chromatic number of a graph and show that this number is estimated algebraically from ideal peaks. Then we present the main theorem of the Diplomatic, Froberg theorem which says that every graph is chordal if and only if the edge ideal of the graph has a linear resolution. Additional studies analyzes the forces of ideals vertex, we show that some of the attached ideals of these forces represent color information for the chart and then we turn our attention to the irreducible analysis of these forces.

description: Σκοπός της παρούσης διατριβής ήταν η μελέτη των διατάξεων του Κώδικα Νόμων του Σέρβου Αυτοκράτορα (Τσάρου) Στεφάνου Δούσαν και των σχέσεων αυτών (αλληλεπίδραση, ομοιότητες, διαφορές και διαδικασία εξέλιξης των) με το Βυζαντινό και το μεσαιωνικό σερβικό δίκαιο. Στην αρχή εξέτασα τις ιστορικές συνθήκες και το πλαίσιο μέσα στο οποίο διαμορφώθηκε ο Κώδικας, μαζί με τις διάφορες παραλλαγές του (εκ διαφορετικών αντιγράφων αυτού, ως έχουν διασωθεί έως σήμερα). Στη συνέχεια παρουσίασα αναλυτικά τις διατάξεις του Κώδικα οι οποίες θεωρούνται τα «νομικά δάνεια» από το Βυζαντινό δίκαιο με τις εξηγήσεις για ποιούς λόγους και από ποιές πηγές ορισμένοι νομικοί θεσμοί του Βυζαντινού δικαίου ενσωματώθηκαν στον Κώδικα. Επίσης, παρουσίασα αναλυτικά και τις διατάξεις του Κώδικα που είναι αυθεντικοί θεσμοί και που ως πηγή τους έχουν το μεσαιωνικό σερβικό δίκαιο. Στο τέλος της διατριβής αναφέρθηκα στα συμπεράσματα μου σχετικά με αυτό το θέμα.
description: The aim of the present thesis was the study of the provisions incorporated in the Code of Laws of the Serbian Emperor (Tsar) Stefan Dusan and their relations (interaction, similarities and differences, as well as development procedure) to the Byzantine Law and the Medieval Serbian Law. In the beginning, I examined the framework and the historical conditions that formed the Code of Laws and it’s variations or different editions (as have been transferred to us by different copies of the Code). Later in the thesis, I present in detail the provisions of the Code that are considered as “legal loans” from Byzantine Law, as well as the explanation of the reasons and the sources that incorporated several provisions and institutions of the Byzantine Law to the Code. Accordingly, I presented the provisions and institutions of the Code that are original and were developed from Medieval Serbian Law. In the end of the thesis, I referred to my conclusions related to this subject.

description: Richard P. Feynman's work on gravitation, as can be inferred from several published and unpublished sources, is reviewed. Feynman was involved with this subject at least from late 1954 to the late 1960s, giving several pivotal contributions to it. Even though he published only three papers, much more material is available, beginning with the records of his many interventions at the Chapel Hill conference in 1957, which are here analyzed in detail, and show that he had already considerably developed his ideas on gravity. In addition he expressed deep thoughts about fundamental issues in quantum mechanics which were suggested by the problem of quantum gravity, such as superpositions of the wave functions of macroscopic objects and the role of the observer. Feynman also lectured on gravity several times. Besides the famous lectures given at Caltech in 1962-63, he extensively discussed this subject in a series of lectures delivered at the Hughes Aircraft Company in 1966-67, whose focus was on astronomy and astrophysics. All this material allows to reconstruct a detailed picture of Feynman's ideas on gravity and of their evolution until the late sixties. According to him, gravity, like electromagnetism, has quantum foundations, therefore general relativity has to be regarded as the classical limit of an underlying quantum theory; this quantum theory should be investigated by computing physical processes, as if they were experimentally accessible. The same attitude is shown with respect to gravitational waves, as is evident also from an unpublished letter addressed to Victor F. Weisskopf. In addition, an original approach to gravity, which closely mimics (and probably was inspired by) the derivation of the Maxwell equations given by Feynman in that period, is sketched in the unpublished Hughes lectures.

description: Оптимизацию организационно-информационных аспектов управленческой деятельности на предприятиях оборонно-промышленного комплекса в современных условиях целесообразно проводить на основе ее моделирования. С помощью экономикоматематических моделей можно выявлять существенные факторы, влияющие на исследуемый процесс управления, и абстрагироваться от деталей, несущественных для его анализа. Без использования данных моделей в процессе оптимизации управленческой деятельности велика вероятность неправильного определения важных взаимосвязей ее организационно-информационных аспектов, влияющих на эффективность управленческих решений. В статье представлены рекомендации по развитию инструментария управленческой деятельности на предприятиях оборонно-промышленного комплекса, учитывающие особенности ее организационно-информационных аспектов.

description: Αντικείμενο της παρούσας εργασίας είναι η αναγνώριση ανθρώπινων δραστηριοτήτων μέσα από δεδομένα βίντεο. Αποτελεί ένα ερευνητικό πεδίο το οποίο τυγχάνει ολοένα μεγαλύτερου ενδιαφέροντος από την ακαδημαϊκή κοινότητα κυρίως λόγω των αυξανόμενων και ενδιαφερουσών εφαρμογών της. Μετά από μια βιβλιογραφική ανασκόπηση της υπάρχουσας προόδου στον τομέα αυτό, εφαρμόζονται δύο κύριες μέθοδοι για την επίλυση του προβλήματος, οι οποίες στηρίζονται στη χρήση των αλγορίθμων των k-μέσων και του LDA. Οι αλγόριθμοι δέχονται ως είσοδο βίντεο που απεικονίζουν ορισμένες ανθρώπινες κινήσεις, οι οποίες ανήκουν στις ευρύτερες κατηγορίες της απραξίας, του φαγητού και του ποτού. Στη βασική μέθοδο η οποία χρησιμοποιεί τον αλγόριθμο των k-μέσων εφαρμόζονται και ορισμένες παραλλαγές για βελτιστοποίηση των αποτελεσμάτων και εξέταση διαφορετικών εναλλακτικών. Τελικά, γίνεται ο υπολογισμός του ποσοστού επιτυχίας κάθε μιας από τις μεθόδους προκειμένου να εντοπιστεί αυτή με την καλύτερη απόδοση, ενώ παρουσιάζεται αναλυτικά όλη η πειραματική διαδικασία που ακολουθήθηκε και τα αποτελέσματα που προέκυψαν. Σαφώς και δεν είναι δυνατόν να εξαντληθεί όλο το εύρος του πεδίου της αναγνώρισης ανθρώπινων δραστηριοτήτων στα πλαίσια μιας διπλωματικής εργασίας. Παρόλα αυτά, η εργασία αυτή αποτελεί μια απόπειρα να καλυφθούν τυχόν προηγούμενα κενά και να δοκιμαστούν νέες δυνατότητες.
description: The present study’s object is the recognition of human activities through video data. It is a research field that receives increasing interest from academia mainly due to rising and interesting applications. After a literature review of the current progress in this area, two main methods are applied to solve the problem, based on the use of k-means and LDA algorithms. The algorithm’s input are videos depicting human movements, belonging to a wider range of apraxia, food and drink. In the basic method, which uses the k-means algorithm are also applied some variations to optimize the results and to examine different alternatives. Ultimately, it is the calculation of the success rate of each of the methods that takes place, in order to identify the one with the best performance, while the experimental procedure that has been followed is presented in detail as well as the results obtained. Clearly it is not possible to run the entire width of the field of recognition of human activities within a thesis. Nevertheless, this work is an attempt to fill any previous gaps and to test new features.
