description: Η ανάλυση της διαχείρισης αποθεμάτων είναι το γοητευτικό και πολυσύνθετο πρόβλημα που παραδοσιακά απασχολεί της εκάστοτε παραγωγική και εμπορική εταιρία. Ένα τέτοιο θέμα δεν θα μπορούσε να μας αφήσει αδιάφορους ακριβώς γιατί μέσω της πολυπλοκότητας αυτού του προβλήματος αναδεικνύονται όροι όπως το κόστος αποθήκευσης, κόστος αναμονής, κόστος αναπαραγγελίας, και παραμετροποιούνται και επιστρατεύονται πολλοί δείκτες ώστε να μπορέσουν να δώσουν τις βέλτιστες εναλλακτικές αντιμετώπισης του συγκεκριμένου προβλήματος στις επιχειρήσεις. Μπορεί να αναφερόμαστε μέσω ενός εύσχημου τρόπου στη σημαντικότητα του συγκεκριμένου θέματος, αυτό όμως δεν σημαίνει ότι με τον ίδιο ακριβώς τρόπο αντιμετωπίζεται και από τις ίδιες τις επιχειρήσεις, οι οποίες πρέπει να αντιληφθούν και να αναλύσουν αυτά τα κόστη που διαμορφώνονται. Να τα προβλέψουν και ταυτόχρονα να εφαρμόσουν τις βέλτιστες πρακτικές αντιμετώπισης των προβληματικών που ανακύπτουν από το συγκεκριμένο ζήτημα. Ακριβώς, στο σημείο αυτό είναι και η καμπή της εξειδίκευσης που απαιτείται από το αρμόδιο τμήμα των επιχειρήσεων που επιστρατεύουν εμπειρία, αλλά και γνώση για να πετύχουν το καλύτερο αποτέλεσμα
description: The Reserve Management analysis is a dazzling and complex problem, which has always occupied with each and every productive and commercial company. Such an issue cannot leave anyone indifferent because through this complexity of this problem, there are other definitions which occur such as storage cost and cost per order and many indexes are called for and put into practice so as to provide the best possible alternative ways of dealing with this problem within the companies. We may use a specious way to refer to the significance of this issue, but this does not mean that the companies themselves deal with this problem in the same way. These companies need to perceive and analyze these formed costs. They should also be able to predict them and to implement the best possible practices of dealing with these problems occurred. This is exactly the specialization point which is demanded by the appropriate departments of each company who call for and put into practice the experience and knowledge of their human resource in order to achieve the best possible result

description: These lectures on Higgs boson collider searches were presented at TASI 2006. I first review the Standard Model searches: what LEP did, prospects for Tevatron searches, the program planned for LHC, and some of the possibilities at a future ILC. I then cover in-depth what comes after a candidate discovery at LHC: the various measurements one has to make to determine exactly what the Higgs sector is. Finally, I discuss the MSSM extension to the Higgs sector.

description: Acoustic systems that are without limitations imposed by the Fermi level have been demonstrated as significant platform for the exploration of fruitful topological phases. By surrounding the nontrivial domain with trivial "environment", the domain-wall topological states have been theoretically and experimentally demonstrated. In this work, based on the topological crystalline insulator with a kagome lattice, we rigorously derive the corresponding Hamiltonian from the traditional acoustics perspective, and exactly reveal the correspondences of the hopping and onsite terms within acoustic systems. Crucially, these results directly indicate that instead of applying the trivial domain, the soft boundary condition precisely corresponds to the theoretical models which always require generalized chiral symmetry. These results provide a general platform to construct desired acoustic topological devices hosting desired topological phenomena for versatile applications.

description: Solid O2 has been proposed as a possible reservoir for oxygen in dense clouds through freeze-out processes. The aim of this work is to characterize quantitatively the physical processes that are involved in the desorption kinetics of CO-O2 ices by interpreting laboratory temperature programmed desorption (TPD) data. This information is used to simulate the behavior of CO-O2 ices under astrophysical conditions. The TPD spectra have been recorded under ultra high vacuum conditions for pure, layered and mixed morphologies for different thicknesses, temperatures and mixing ratios. An empirical kinetic model is used to interpret the results and to provide input parameters for astrophysical models. Binding energies are determined for different ice morphologies. Independent of the ice morphology, the desorption of O2 is found to follow 0th-order kinetics. Binding energies and temperature-dependent sticking probabilities for CO-CO, O2-O2 and CO-O2 are determined. O2 is slightly less volatile than CO, with binding energies of 912+-15 versus 858+-15 K for pure ices. In mixed and layered ices, CO does not co-desorb with O2 but its binding energies are slightly increased compared with pure ice whereas those for O2 are slightly decreased. Lower limits to the sticking probabilities of CO and O2 are 0.9 and 0.85, respectively, at temperatures below 20K. The balance between accretion and desorption is studied for O2 and CO in astrophysically relevant scenarios. Only minor differences are found between the two species, i.e., both desorb between 16 and 18K in typical environments around young stars. Thus, clouds with significant abundances of gaseous CO are unlikely to have large amounts of solid O2.

description: We discuss the possible impact of astrophysical neutrino flux measurements at neutrino telescopes on the neutrino oscillation program of reactor experiments and neutrino beams. We consider neutrino fluxes from neutron sources, muon damped sources, and pion sources, where we parameterize the input from these sources in terms of the flux ratio $R=ϕ_μ/(ϕ_e+ϕ_τ)$ which can be extracted from the muon track to shower ratio in a neutrino telescope. While it is difficult to obtain any information from this ratio alone, we demonstrate that the dependence on the oscillation parameters is very complementary to the one of reactor experiments and neutrino beams. We find that for large values of $\sin^2 2 θ_{13}$, a measurement of R with a precision of about 20% or better may not only improve the measurement of the leptonic CP phase, but also help the determination of the mass hierarchy. In some cases, early information on $δ_{CP}$ may even be obtained from Double Chooz and an astrophysical flux alone without the help of superbeams. For small values of $\sin^2 2 θ_{13}$, we find that using the information from an astrophysical neutrino flux could eliminate the octant degeneracy better than reactor experiments and beams alone. Finally, we demonstrate that implementing an additional observable based on the electromagnetic to hadronic shower ratio at a neutrino telescope (such as at higher energies) could be especially beneficial for pion beam sources.

description: Sensory neuroscience seeks to understand how the brain encodes natural environments. However, neural coding has largely been studied using simplified stimuli. In order to assess whether the brain's coding strategy depend on the stimulus ensemble, we apply a new information-theoretic method that allows unbiased calculation of neural filters (receptive fields) from responses to natural scenes or other complex signals with strong multipoint correlations. In the cat primary visual cortex we compare responses to natural inputs with those to noise inputs matched for luminance and contrast. We find that neural filters adaptively change with the input ensemble so as to increase the information carried by the neural response about the filtered stimulus. Adaptation affects the spatial frequency composition of the filter, enhancing sensitivity to under-represented frequencies in agreement with optimal encoding arguments. Adaptation occurs over 40 s to many minutes, longer than most previously reported forms of adaptation.

description: We study the anomalous Hall conductivity in spin-polarized, asymmetrically confined two-dimensional electron and hole systems, focusing on skew-scattering contributions to the transport. We find that the skew scattering, principally responsible for the extrinsic contribution to the anomalous Hall effect, vanishes for the two-dimensional electron system if both chiral Rashba subbands are partially occupied, and vanishes always for the two-dimensional hole gas studied here, regardless of the band filling. Our prediction can be tested with the proposed coplanar two-dimensional electron/hole gas device and can be used as a benchmark to understand the crossover from the intrisic to the extrinsic anomalous Hall effect.

Ο αλγόριθμος που υλοποιήθηκε τροφοδοτείται με φυλογενετικά προφίλ που αντιστοιχούν σε πρωτεΐνες διάφορων οργανισμών και παράγει μια ομαδοποίηση πρωτεινών. Επειδή σχετίζεται άμεσα με τον τομέα της βιολογίας και της βιοπληροφορικής ο αλγόριθμος δημιουργεί μια ομαδοποίηση επιθυμητή και αποδοτική σε όλα τα επίπεδα. Όσον αφορά τον χρόνο υλοποίησης, ο ιεραρχικός αλγόριθμος δημιουργήθηκε με τέτοιο τρόπο ώστε να είναι εφικτή η παράλληλη δημιουργία ομάδων. Ο χρόνος υλοποίησης είναι πεπερασμένος και η αύξησή του παραμένει σε λογικά πλαίσια όταν αυξάνεται το πλήθος ή η διάσταση των δεδομένων. Το κυρίως πρόβλημα που αντιμετωπίζεται είναι η χρήση της μνήμης κύριας προσπέλασης, η οποία δεν επαρκεί για την αποθήκευση και την επεξεργασία των δεδομένων μεγάλου όγκου. Για την επίλυση αυτού του προβλήματος, ο ιεραρχικός αλγόριθμος ομαδοποίησης που δημιουργήθηκε χρησιμοποιεί αρχεία κειμένου. Η χρήση της μνήμης κύριας προσπέλασης παραμένει σταθερή κατά την αύξηση των διαστάσεων ή του πλήθους των δεδομένων
description: The aim is to create a hierarchical clustering algorithm, which can cluster Big biological Data. The algorithm implemented is fed with phylogenetic profiles corresponding to different proteins and produces a clustering of proteins. So, the algorithm is directly related to the field of biology and bioinformatics and with this in mind it should create a clustering effective from all aspects. The main problem encountered with Big Data is the use of random access memory (RAM), which is not sufficient for storing and processing. To prevent and eliminate this problem, the hierarchical clustering algorithm uses text files. Overall the usage of random access memory is constant and significantly lower than in normal use. It is obvious that when referring to big data we give special attention to the implementation time so that it is not growing rapidly along with the increase of data. Regarding the implementation time the hierarchical algorithm is created in a way that simultaneous clustering is possible. The results shows that the implementation time is finite and increases reasonably when increasing the number or dimensionality of the data used

description: We present the first astronomical observations obtained with an Apodizing Phase Plate (APP). The plate is designed to suppress the stellar diffraction pattern by 5 magnitudes from 2-9 lambda/D over a 180 degree region. Stellar images were obtained in the M' band (4.85 microns) at the MMTO 6.5m telescope, with adaptive wavefront correction made with a deformable secondary mirror designed for low thermal background observations. The measured PSF shows a halo intensity of 0.1% of the stellar peak at 2 lambda/D (0.36 arcsec), tapering off as r^{-5/3} out to radius 9 lambda/D. Such a profile is consistent with residual errors predicted for servo lag in the AO system. We project a 5 sigma contrast limit, set by residual atmospheric fluctuations, of 10.2 magnitudes at 0.36 arcsec separation for a one hour exposure. This can be realised if static and quasi-static aberrations are removed by differential imaging, and is close to the sensitivity level set by thermal background photon noise for target stars with M'>3. The advantage of using the phase plate is the removal of speckle noise caused by the residuals in the diffraction pattern that remain after PSF subtraction. The APP gives higher sensitivity over the range 2-5 lambda/D compared to direct imaging techniques.

description: The catastrophic Armenian genocide of 1915 has long set the trend for the study of intercommunal relations between Kurdish and Christian groups of Ottoman East Anatolia and northwest Iran. In the process, Russian and the Ottoman Empires have been identified as key players in exploiting ethnoreligious distinctions to the advantage of imperial centers and at the expense of the inhabitants of Ottoman East Anatolia. However, the crucial impact that the process of Ottoman-Iranian boundary-making left on intercommunal relations has been understudied. This dissertation traces the impact of the frontier delimitation process on intercommunal relations among ethnoreligious groups straddling the northwest stretch of the Ottoman-Iranian borders. This study proposes that the process of making the Ottoman-Iranian boundaries, which involved redefinitions of sovereignty and subjecthood as preambles to the emergence of the modern states of Iran and Turkey, led to an intense imperial rivalry over the religious identity of imperial subjects of the frontier. Interest and investment in the religious identities of overlapping borderland populations sprang from rival empires’ desire to rejuvenate their compromised sovereignty among their frontiers through strengthening their loyalty and allegiance. The presence of foreign missions and consuls and native subjects with extralegal statuses complicated such imperial efforts, and ultimately worked as contributing factor to the sectarianization of the borderland populations’ communal visions and boundaries. The missions, foreign consuls, and travelers helped to construct a sectarian narrative of intercommunal conflict as they too stressed the religious distinctions of different communities through disproportionate attention to the welfare and education of the Christian minorities. Over time, imperial and missionary rivalry and discriminatory policies of prioritizing the wishes of one group over another’s, led to the emergence of sectarian communities with distinctive communal boundaries and aspirations that could hardly be reconciled. When wartime conditions were imposed on the borderland populations in 1915, sectarianized communities brutalized each other, sending untold number of people to their deaths in the process
Priming the cognitive pump : implicit memory and navigating multiple window interfaces

Publisher: name: University of British Columbia

description: When navigating through large-scale information spaces, users may lose track of their location and experience the sensation of being “lost in hyperspace”. A common solution applied to this problem is the graphical user interface, using windows to keep track of the pages visited, to show overview maps of the information space, and to highlight information “landmarks”, all of them serving the user as reminders in support of the task at hand. My thesis focuses on two different types of memory or memory processes--implicit and explicit-- and explores how these may be harnessed in the design of human-computer interfaces. Explicit memory is reflected in tests of conscious recall or recognition of a past event or experience. Implicit memory is revealed through improved performance on tasks that do not require conscious or intentional recollection of previously studied information. I carried out an experiment that used a menu-item selection task, with window arrangement and text justification as the independent variables, where both implicit and explicit memory were assessed. Implicit memory testing focused on the acquisition of a menu-item selection skill under different menu-item mapping conditions; explicit memory testing required recollecting the correct position of target menu-items with the aid of previously seen window displays. Forty undergraduate student volunteers served as subjects. The implicit memory test results showed no effects due to various window arrangement and text justification manipulations. By contrast, explicit memory test performance showed an overall increase in menu-item selection accuracy, an improvement in accuracy across trials, and in addition, it also showed a significant difference in selection accuracy with left- versus right-justified text. The discussion focuses on various aspects of these findings; it explores limits of the present study and outlines plans for future investigations, as well as implications for window management and information presentation.

description: We study both classical and quantum algorithms to solve a hard optimization problem, namely 3-XORSAT on 3-regular random graphs. By introducing a new quasi-greedy algorithm that is not allowed to jump over large energy barriers, we show that the problem hardness is mainly due to entropic barriers. We study, both analytically and numerically, several optimization algorithms, finding that entropic barriers affect in a similar way classical local algorithms and quantum annealing. For the adiabatic algorithm, the difficulty we identify is distinct from that of tunnelling under large barriers, but does, nonetheless, give rise to exponential running (annealing) times.

description: The main objective of this dissertation is to analyze the use of male stereotypes in the advertising of American Football (Super Bowl). The thesis is separated into the following chapters. In the first chapter we study the stereotypes use of male and female in the advertising. We also referred to the loser man and the analysis of Super Bowl. In the second chapter entitled “Researching relations” we analyze the following: H1: The advertising becomes more popular if a loser man is described as loser. H2: The advertising becomes more popular if a loser man in unemployed. H3: The advertising becomes more popular if a loser man is presented is doing housekeeping. H4: The advertising becomes more popular within the male audience if a loser man is presented in the advertising. H5: The advertising of low mix products such as chewing gum, beers, becomes more popular if a loser man is presented in the advertising. In the next chapter, Chapter 4, we present the methodologies such as the sample, the typology, the process and the statistical method (ANOVA) that is used. The fifth chapter lists all the results obtained from the research cases. In the last chapters we present the conclusions from the analysis, the proposals to the advertiser and future research

Η ποιοτική και ποσοτική ανάλυση αποτελεσμάτων έγινε σε δύο φάσεις. Η πρώτη έγινε σχετικά με την ανάλυση περιεχομένου μεταξύ των δύο χωρών και η δεύτερη φάση μεταξύ του αν χρησιμοποίησαν τη αναφερόμενη τεχνική έκκλησης συναισθημάτων ή όχι. Το επόμενο βήμα ήταν η παρουσίαση των ερευνητικών υποθέσεων. Στη συνέχεια, μέσα από τα τελικά αποτελέσματα- συμπεράσματα της έρευνας, εξηγήθηκε η επιβεβαίωση των υποθέσεων. Τέλος, παρουσιάστηκαν οι ενδεχόμενες προτάσεις προς τους διαφημιστές για το μέλλον, όπως το τι θα μπορούσαν να λάβουν υπόψιν τους καθώς και οι προτάσεις για μελλοντικές έρευνες
description: In the present study, we conducted qualitative and quantitative analyses of the ways in which emotions were utilized in political advertisements during the two referenda which occurred in Greece in 2015 and in the United Kingdom in 2016. To begin, we defined the basic concepts surrounding political advertisements as well as their relationship to the appeal to emotions. In accordance with the study’s methodology, we presented on the one hand the laws and the political establishments which govern the two countries and on the other, the similarities and differences between the two referenda. Afterward, an analytical description was given of the various techniques which can be utilized in emotional appeals, presenting the results for each technique separately. The qualitative and quantitative analyses of the results occurred in two phases. The first consisted of a content analysis comparing the two countries and the second consisted of whether they used the above-mentioned techniques of emotional appeal or not. The next step was the presentation of our research hypotheses. Subsequently, within the final results-conclusions of the study, we explained how our hypotheses were confirmed. Finally, possible proposals for advertisers in the future were put forward based on what they could have taken into account as well as making proposals for further research

description: Η παρούσα μελέτη αποσκοπεί να σκιαγραφήσει την πορεία ενσωμάτωσης του προσφυγικού πληθυσμού που έφτασε στη Σύρο του Μεσοπολέμου, μετά από τη Μικρασιατική καταστροφή του 1922. Σκοπός είναι να αναδειχθεί ο βαθμός ενσωμάτωσης του προσφυγικού κύματος σε μία πόλη, με μόλις έναν αιώνα ζωής, που η προσφυγική ταυτότητα αποτελεί απερίσπαστο στοιχείο της σύστασης και του πολιτισμού της. Μέσα λοιπόν από την δράση της τοπικής κοινωνίας για την πρώτη ανακούφισή τους, τη σύμπνοια των δύο κοινοτήτων με το πέρασμα του χρόνου, την πορεία της εγκατάστασής τους, τη συνεισφορά του προσφυγικού κόσμου στην οικονομική ζωή της πόλης και τέλος την πολιτική του ενεργοποίηση στο νέο πλαίσιο, επιχειρείται μια προσπάθεια καταγραφής της πορείας ένταξης και ενσωμάτωσης του νέου αυτού προσφυγικού πληθυσμού από έναν εξίσου προσφυγικό πληθυσμό και της ευκαιρίες αλληλεπίδρασης κατά τη δημιουργία ενός νέου κοινωνικού μορφώματος
description: The present thesis aims to outline the process of integration of the refugee population that arrived in interwar Syros after the Asia Minor disaster of 1922. The aim is to highlight the degree of integration of the refugee wave in a city, only a century old, which the refugee identity is an undisturbed part of the recommendation and its culture. Thus, through the action of the local community for their first relief, the unity of the two communities with the passage of time, the course of their installation, the contribution of the refugee world in the city's economic life and, finally, the policy of activation in the new context is an attempt to record the integration course and integration of this new refugee population by an equally refugee population and interaction opportunities while creating a new social construct
Filtering volumetric data
Creators: name: Buchanan, John W.
Publisher: name: University of British Columbia

description: The display of volumetric data is a problem of increasing importance: The display of this data is being studied in texture mapping and volume rendering applications. The goal of texture mapping is to add variation to the surfaces that is not caused by the geometric models of the objects. The goal of volume rendering is to display the data so that the study of this data is made easier. Three-dimensional texture mapping requires the use of filtering not only to reduce aliasing artifacts but also to compute the texture value which is to be used for the display. Study of two-dimensional texture map filtering techniques led to a number of techniques which were extended to three dimensions: namely clamping, elliptical weighted average (EWA) filters, and a pyramidal scheme known as NIL maps; (NIL stands for nodus in largo, the rough translation of which is knot large). The use of three-dimensional textures is not a straightforward extension of the use of two-dimensional textures. Where two-dimensional textures are usually discrete arrays of texture samples which are applied to the surface of objects, three-dimensional textures are usually procedural textures which can be applied on the surface of an object, throughout the object, or in volumes near the object. We studied the three-dimensional extensions of clamping, EWA filters, and NIL maps for filtering these textures. In addition to these three techniques a direct evaluation technique based on quadrature methods is presented. The performance of these four techniques is compared using a variety of criteria, and recommendations are made regarding their use. There are several techniques for volume rendering which can be formulated as filtering operations. By altering these display filters different views of the data can be generated. We modified the NIL map filtering technique for use as a filter-prototyping tool. This extension incorporated transfer functions into the NIL map technique. This allows the manipulation of the transfer functions without requiring the re-computation of the NIL maps. The use of NIL maps as a filter-prototyping tool is illustrated with a series of examples.

description: In null electromagnetic fields the electric and the magnetic field lines evolve like unbreakable elastic filaments in a fluid flow. In particular, their topology is preserved for all time. We prove that for every link $L$ there is such an electromagnetic field that satisfies Maxwell's equations in free space and that has closed electric and magnetic field lines in the shape of $L$ for all time.
Modeling Multiple M2's

description: We investigate the worldvolume theory that describes N coincident M2-branes ending on an M5 brane. We argue that the fields that describe the transverse spacetime coordinates take values in a non-associative algebra. We postulate a set of supersymmetry transformations and find that they close into a novel gauge symmetry. We propose a three-dimensional N=2 supersymmetric action to describe the truncation of the full theory to the scalar and spinor fields, and show how a Basu-Harvey fuzzy funnel arises as the BPS solution to this theory.

Progress in D-brane model building

description: The state of the art in D-brane model building is briefly reviewed, focusing on recent achievements in the construction of D=4 N = 1 type II string vacua with semi-realistic gauge sectors. Such progress relies on a better understanding of the spectrum of BPS D-branes, the effective field theory obtained from them and the explicit construction of vacua. We first consider D-branes in standard Calabi-Yau compactifications, and then the more involved case of compactifications with fluxes. We discuss how the non-trivial interplay between D-branes and fluxes modifies the previous model-building rules, as well as provides new possibilities to connect string theory to particle physics.

description: Physics event generators are essential components of the data analysis software chain of high energy physics experiments, and important consumers of their CPU resources. Improving the software performance of these packages on modern hardware architectures, such as those deployed at HPC centers, is essential in view of the upcoming HL-LHC physics programme. In this paper, we describe an ongoing activity to reengineer the Madgraph5_aMC@NLO physics event generator, primarily to port it and allow its efficient execution on GPUs, but also to modernize it and optimize its performance on vector CPUs. We describe the motivation, engineering process and software architecture design of our developments, as well as the current challenges and future directions for this project. This paper is based on our submission to vCHEP2021 in March 2021,complemented with a few preliminary results that we presented during the conference. Further details and updated results will be given in later publications.

Configuration management using objects and constraints
Creators: name: Coatta, Terry
Publisher: name: University of British Columbia
Year: 2009

description: Distributed programming techniques have transformed applications into federations of cooperating semi-autonomous components. Complex interactions between these components create complex interdependencies which are quickly outstripping the capacity of human systems managers. Adding configuration management features to an application’s components reduces the flexibility and portability of those components. This thesis develops a new model of configuration management designed to address these issues. To respond to the wide variety of situations in which configuration management is required, the model is universal, addressing with one formalism many different types of configuration management tasks. In order to reduce reliance on human systems managers, the model describes configuration management as an active process carried out by the computer itself. Finally, as the need for automated configuration management is most acute in distributed systems, the model provides for the distribution of configuration management activities. This new model of configuration management is the basis for the design of a new configuration management tool, the Raven Configuration Management System (RCMS). RCMS provides an environment in which configuration management is handled orthogonally to the task of programming individual components. RCMS allows a programmer to group related components together and specify rules which govern their interactions. RCMS combines object-oriented structuring with declarative programming to produce a system which provides improved reliability and performance in the presence of an evolving environment. The core of RCMS is a new configuration programming language called the Raven Configuration Language (RCL). This thesis describes the implementation of RCMSIRCL. This implementation demonstrates that the language constructs of RCL can be performed with acceptable efficiency, and it establishes the sort of services required to implement a universal, active, and distributed configuration management system. Finally, this thesis discusses several interesting implementation techniques that address particular problems which arose during the implementation of RCMS/RCL.
