description: H διατριβή αυτή έχει ως στόχο να διερευνήσει πώς ένας χάρτης διαδικασιών μπορεί να επηρεάσει μια επιχείρηση, πώς ο προσδιορισμός των σημείων συμφόρησης μπορεί να συμβάλει στη βελτίωση της εμπειρίας που προσφέρουν στους πελάτες τους και γιατί η ποιότητα των υπηρεσιών είναι σημαντική. Προκειμένου να υποστηρίξει επαρκώς το σκοπό της έρευνας, αναπτύχθηκε ένα μοντέλο που βασίζεται σε προηγούμενες θεωρίες και τα θεμελιώδη μοντέλα σε συνδυασμό με ειδικά χαρακτηριστικά της εταιρίας Coffee Island, με στόχο να ανακαλύψει τις εμπειρίες που μπορούν να αποκτήσουν οι πελάτες της εταιρίας κατά την διάρκεια που απολαμβάνουν τον καφέ τους. Λόγω της φύσης της έρευνας, μία ποσοτική μέθοδος έρευνας και συλλογής δεδομένων διεξήχθη για να ικανοποιήσει τις ανάγκες της διπλωματικής. Για να συγκεντρωθούν τα δεδομένα, μια έρευνα ερωτηματολογίου διεξήχθη για το σκοπό της μελέτης. Συνολικά, τα αποτελέσματα αυτής της διατριβής επιβεβαίωσαν προηγούμενες ακαδημαϊκές σπουδές στον τομέα της ποιότητας εξυπηρέτησης των πελατών και συνεπώς τα ευρήματα συμβάλλουν στην κατανόηση αν ένας χάρτης διαδικασιών των υπηρεσιών μπορεί να επηρεάσει την ποιότητα των υπηρεσιών.
description: Τhis paper aims to investigate how a blueprint can affect a business, how the identification of bottlenecks can help improve the experience they offer to their customers, and why service quality is important. In order to adequately support the purpose of the research, a model was developed based on previous theories and fundamental models in combination with Coffee Island’s specific features, aiming to find out the aspects customers could experience when having their coffee on a specific branch of Coffee Island. Due to the nature of the research, a quantitative research method and data collection was conducted to satisfy the needs of the paper. In order to gather the data, a questionnaire survey was conducted for the purpose of the study. Overall, the results of this thesis confirmed previous academic studies in the field of customer service quality and the findings thus contribute to our understanding if a services blueprinting can affect service quality.

description: Η ανάδυση και η εγκαθίδρυση των μέσων κοινωνικής δικτύωσης στην καθημερινότητα μας, ως αποτέλεσμα της άνθησης του Διαδικτύου, έχουν προκαλέσει μια σειρά αλλαγών σε διάφορα πεδία. Ένα από αυτά είναι και η δημοσιογραφία καθώς επίσης και ο τρόπος ενημέρωσης. Το νέο πεδίο που έχει δημιουργηθεί στη βιομηχανία των μέσων είναι συναρπαστικό με την παραδοσιακή δημοσιογραφία να δίνει τη σκυτάλη της σε αυτή που αποκαλείται «δημοσιογραφία των πολιτών» ή «δημοσιογραφία από τα κάτω», όροι που εξηγούν τη δημοσιογραφία που παράγεται από τους πολίτες. Μάλιστα, οι αλλαγές αυτές συντελούνται, ενώ μια ολόκληρη γενιά ανθρώπων εκλαμβάνει τη νέα κατάσταση ως θέσφατο, μη έχοντας ζήσει την προ - νέων τεχνολογιών εποχή. Πρόκειται για τη γενιά που ακούει στο όνομα «Millennials». Η παρούσα εργασία, λοιπόν, επιχειρεί στο πρώτο μέρος να αναλύσει τα μέσα κοινωνικής δικτύωσης, το νέο πεδίο της δημοσιογραφίας, καθώς και τα χαρακτηριστικά της νέα «ψηφιακής» γενιάς, όχι μόνο βιβλιογραφικά, αλλά παρουσιάζοντας και συγκρίνοντας πρότερες έρευνες που εστιάζουν στο θέμα ενδιαφέροντος. Ακολουθεί στο δεύτερο μέρος το ερευνητικό κομμάτι, το οποίο δημιουργήθηκε με την ποιοτική μέθοδο των ομάδων εστίασης (focus groups) και η ανάλυση της έρευνας σχετικά με τον τρόπο κατανάλωσης ειδήσεων από τους νέους στην Ελλάδα.
description: A new landscape has been already created in media industry as news consumption is conveyed to the Internet. The past years, traditional journalism is waning, giving its place to what it’s called ‘citizen journalism’ or/and ‘grassroots journalism’ These terms concern to new kind of journalism coming direct from the audience, transforming the way we stay informed. Furthermore, Millennials are the generation who grew up using massively the Internet, whom we may call ‘digital natives’ or/and Generation Y. The massive use of the Internet in recent years and the rise of Social Media in our daily lives have changed not only the way we communicate and interact but also how we consume news. Young people are affected by these improvements as they grew up using broadly social media, thus changing the previous model on the use of traditional media. Moreover, recent research indicated the variation of young people from traditional media, such as newspapers and TV to the widespread acceptance of new media and especially social media. The interesting part of how young people consume news is now coming to the fore. This dissertation has two parts: on the first, we studied all these changes, analyzing the terms and the history of social media, the new field of journalism and the new generation called “Millennials”. On the second part, it comes the empirical research based on two focus groups.
Discovery of a 3.6-hr Eclipsing Luminous X-Ray Binary in the Galaxy NGC 4214

description: We report the discovery of an eclipsing X-ray binary with a 3.62-hr period within 24" of the center of the dwarf starburst galaxy NGC 4214. The orbital period places interesting constraints on the nature of the binary, and allows for a few very different interpretations. The most likely possibility is that the source lies within NGC 4214 and has an X-ray luminosity of up to 7 e38 ergs/s. In this case the binary may well be comprised of a naked He-burning donor star with a neutron-star accretor, though a stellar-mass black-hole accretor cannot be completely excluded. There is no obvious evidence for a strong stellar wind in the X-ray orbital light curve that would be expected from a massive He star; thus, the mass of the He star should be <3-4 solar masses. If correct, this would represent a new class of very luminous X-ray binary -- perhaps related to Cyg X-3. Other less likely possibilities include a conventional low-mass X-ray binary that somehow manages to produce such a high X-ray luminosity and is apparently persistent over an interval of years; or a foreground AM Her binary of much lower luminosity that fortuitously lies in the direction of NGC 4214. Any model for this system must accommodate the lack of an optical counterpart down to a limiting magnitude of 22.6 in the visible.

description: Η Ορθόδοξη μαρτυρία στην Κολομβία συνδέεται άρρηκτα με τη λειτουργική ζωή των πιστών. Ωστόσο η απόδοση όλων των λειτουργικών βιβλίων στην ισπανική γλώσσα παραμένει ακόμη ένα σοβαρό πρόβλημα, εφόσον χρειάζεται μία κοινή συντονισμένη πρωτοβουλία από τους εκπροσώπους όλων των Ορθοδόξων δικαιοδοσιών, προκειμένου να καταλήξουν τουλάχιστον σ’ ένα κοινό επικαιροποιημένο Ευχολόγιο. Εξάλλου ιδιαίτερα στην ιεραποστολική Εκκλησία της Κολομβίας οι κοινωνικές και οι πολιτικές συνθήκες δημιουργούν επιπρόσθετα λειτουργικά προβλήματα, όπως για παράδειγμα η ακολουθία για νεκρούς που έχουν αποτεφρωθεί χωρίς τη δική τους βούληση, αλλά με απόφαση των οικείων τους που δεν αντέχουν το κόστος της ταφής. Επίσης η συνύπαρξη με άλλες χριστιανικές ομολογίες και η πίεση να δίνονται απαντήσεις σε ποικίλα ποιμαντικά θέματα ορθόδοξης μαρτυρίας που αντανακλούν και στη λατρεία της Εκκλησίας, όπως οι μεικτοί γάμοι και το χρίσμα των ετεροδόξων, χρειάζονται υπεύθυνες απαντήσεις και ουσιαστική μέριμνα από την Ορθόδοξη Εκκλησία και ιδιαίτερα το Οικουμενικό Πατριαρχείο.
description: The Orthodox witness in Colombia is closely linked to the liturgical life of the faithful. However, the translation of liturgical texts into Spanish is still a serious problem. Therefore, a coordinated effort by representatives of all the Orthodox Jurisdictions is needed to at minimum agree to work for a common Evchologion. Furthermore, sociopolitical issues pose additional problems, such as the funeral service for those faithful who have passed away and have been cremated not of their own will, but by a decision of their relatives due to a lack of money for a proper burial, due to graves that are highly taxed. Likewise, the coexistence with other Christian confessions and the pressure to answer the numerous pastoral issues according to an Orthodox witness reflecting into the worship of the Church, such as mixed marriage and the Chrismation of heterodox, demands responsible answers and careful care by the Orthodox Church, especially the Ecumenical Patriarchate

description: The purpose of this paper is to show how the problem of finding the zeros of unilateral n-order quaternionic polynomials can be solved by determining the eigen-vectors of the corresponding companion matrix. This approach, probably superfluous in the case of quadratic equations for which a closed formula can be given, becomes truly useful for (unilateral) n-order polynomials. To understand the strehgth of this method, we compare it with the Niven algorithm and show where this (full) matrix approach improves previous methods based on the use of the Niven algorithm. For the convenience of the readers, we explicitly solve some examples of second and third order unilateral quaternionic polynomials. The leading idea of the practical solution method proposed in this work can be summarized in following three steps: translating the quaternionic polynomial in the eigenvalue problem for its companion matrix, finding its eigenvectors, and, finally, giving the quaternionic solution of the unilateral polynomial in terms of the components of such eigenvectors. A brief discussion on bilateral quaternionic quadratic equations is also presented.

description: Σκοπός της διατριβής ήταν η μελέτη του μοτίβου της Χρυσής Εποχής, όπου και όπως εμφανίζεται στο έργο του Βιργιλίου τον 1ο προχριστιανικό αιώνα. Αρχικά, εξετάζεται η προ-βιργιλιανή παρουσία του μοτίβου ήδη από τον Ησίοδο τον 7ο π.Χ. αιώνα. Στη συνέχεια δίνεται έμφαση στην πρόσληψη αυτού από τον Βιργίλιο και στις αλλαγές που επέφερε. Το μοτίβο εμφανίζεται στην 4η εκλογή, στα Γεωργικά και στην Αινειάδα. Η εργασία είναι κειμενοκεντρική, ενώ περιλαμβάνει και πολιτικές προεκτάσεις. Ο Βιργίλιος πρωτοτυπεί και προσλαμβάνει την Χρυσή Εποχή με έναν διαφορετικό τρόπο από τους προκατόχους του, ενώ διαφορετική πρόσληψη του μοτίβου αναγνωρίζεται και στα επιμέρους έργα του. Η νοσταλγία που εκφράζεται μέσα από το μοτίβο για μια ευδαίμονα παρελθούσα εποχή και η απογοήτευση του οδυνηρού παρόντος αγγίζει τον σύγχρονο αναγνώστη που επιβιώνει μέσα σε τόσο δύσκολους καιρούς, ενώ συχνά αναπολεί τα παλιότερα χρόνια. Ο Βιργίλιος βιώνει στα χρόνια του μια έντονη κρίση και παρόλα αυτά παραμένει αισιόδοξος και οραματίζεται τη βελτίωση της οδυνηρής αυτής κατάστασης μέσα από το μοτίβο της Χρυσής Εποχής.
description: The aim of the present thesis was the study of the Golden Age motif, wherever it appears in Virgil’s work in the 1st century BC. First I examine the presence of this motif before Virgil’s time as far back as Hesiod’s in 7th century BC. Then I focused on how Virgil incorporates this literary motif in his work and on the changes he made on it. This motif appears in the 4th eclogue, the Georgics and the Aeneid. My thesis focus on the text, while includes political implications. Virgil innovates and uses the Golden Age motif in a different way than his predecessors, while a motif’s different intake is recognized in each one of his works. The nostalgia expressed through the motif for a prosperous past time and the frustration of this painful present touches the modern reader who survives in such a difficult period, while often reminisces about the past years. Virgil experienced an intense crisis during his years and nevertheless remained optimistic and envisaged the improvement of this dolorous situation through the Golden Age motif.

description: A relativistic version of the coupled-cluster single-double (CCSD) method is developed for atoms with a single valence electron. In earlier work, a linearized version of the CCSD method (with extensions to include a dominant class of triple excitations) led to accurate predictions for energies, transition amplitudes, hyperfine constants, and other properties of monovalent atoms. Further progress in high-precision atomic structure calculations for heavy atoms calls for improvement of the linearized coupled-cluster methodology. In the present work, equations for the single and double excitation coefficients of the Dirac-Fock wave function, including all non-linear coupled-cluster terms that contribute at the single-double level are worked out. Contributions of the non-linear terms to energies, electric-dipole matrix elements, and hyperfine constants of low-lying states in alkali-metal atoms from Li to Cs are evaluated and the results are compared with other calculations and with precise experiments.

From history to poetry

description: Το κύριο αντικείμενο της παρούσας μελέτης είναι τα δώδεκα ποιήματα του Καβάφη που αναφέρονται στον αυτοκράτορα Ιουλιανό. Η μελέτη επικεντρώνεται σε εκείνα τα σημεία της ζωής και της δράσης του Ιουλιανού, που τράβηξαν την προσοχή του ποιητή και έγιναν αντικείμενο των ποιημάτων του. Το κείμενο αποτελείται από τρία μέρη. Το πρώτο μέρος αναφέρεται στον ποιητή και ασχολείται κυρίως με τον τρόπο που εργάζεται στα ιστορικά του ποιήματα. Το δεύτερο μέρος αναφέρεται στη ζωή και τη δράση του Ιουλιανού, με έμφαση στη θρησκευτική φυσιογνωμία του, επειδή αυτό το χαρακτηριστικό του προσέλκυσε το ενδιαφέρον του δημιουργού. Το τρίτο μέρος αναφέρεται στα «ιουλιανά» ποιήματα του Καβάφη και είναι το σημείο στο οποίο αναλύονται τα δώδεκα ποιήματα. Η σκοπιά προσέγγισης είναι ιστορική και βασίζεται στη μελέτη των πρωτογενών πηγών. Ο ποιητής, απ’ την πλευρά του, κινείται από την ιστορία στην ποίηση, υπό την έννοια ότι, κατ’ αρχάς, διεξάγει μια λεπτομερή εξέταση των πρωτογενών πηγών και, στη συνέχεια, γράφει τα ποιήματά του, γεγονός που υπαγορεύει και τον τίτλο της εργασίας: «Από την ιστορία στην ποίηση: Ο κατά Καβάφην Ιουλιανός»
description: The main subject of the present study is the twelve poems which Cavafy wrote about Julian, the emperor. The study focuses on these points of Julian' s life and action which drew Cavafy's attention and became theme of his poems. The text consists of three parts. The first part refers to the poet himself and mainly illustrates how he works on his historical poems. Additionally, the second part describes Julian’s life and action and centers on his religious profile as this is the point that attracted the creator’s interest. Finally, the third part is devoted to the "Julian" poems of Cavafy and it is the part in which the twelve poems are examined. The approach angle is historical and it is based on the study of primary sources. The poet, from his side, moves “from history to poetry”, meaning that he initially conducts a detailed examination of primary sources and subsequently he writes his poems, which is a fact that dictates the work’s title: “From history to poetry: Cavafy’s Julian”.
Fluctuations of fragment observables

description: This contribution presents a review of our present theoretical as well as experimental knowledge of different fluctuation observables relevant to nuclear multifragmentation. The possible connection between the presence of a fluctuation peak and the occurrence of a phase transition or a critical phenomenon is critically analyzed. Many different phenomena can lead both to the creation and to the suppression of a fluctuation peak. In particular, the role of constraints due to conservation laws and to data sorting is shown to be essential. From the experimental point of view, a comparison of the available fragmentation data reveals that there is a good agreement between different data sets of basic fluctuation observables, if the fragmenting source is of comparable size. This compatibility suggests that the fragmentation process is largely independent of the reaction mechanism (central versus peripheral collisions, symmetric versus asymmetric systems, light ions versus heavy ion induced reactions). Configurational energy fluctuations, that may give important information on the heat capacity of the fragmenting system at the freeze out stage, are not fully compatible among different data sets and require further analysis to properly account for Coulomb effects and secondary decays. Some basic theoretical questions, concerning the interplay between the dynamics of the collision and the fragmentation process, and the cluster definition in dense and hot media, are still open and are addressed at the end of the paper. A comparison with realistic models and/or a quantitative analysis of the fluctuation properties will be needed to clarify in the next future the nature of the transition observed from compound nucleus evaporation to multi-fragment production.

description: This study employs the Driver-Pressure-State-Impact-Response (DPSIR) framework to explore coastal litter in Pangandaran's coastal areas, analyzing the effects of socio-economic and cultural activities on the environment. Focused on the dynamic coastal ecosystems, it examines how tourism, fishing, and other human activities contribute to environmental degradation through coastal litter, impacting marine life, habitats, and human health, thereby influencing socio-economic outcomes. Pangandaran District serves as a case study to understand the interplay between human activities and environmental pressures, highlighting the challenges of managing coastal litter due to insufficient waste management and low environmental awareness. The research assesses the causality chain within the DPSIR framework, from socio-economic drivers through to the need for strategic responses, including education and sustainable practices aimed at achieving ecological, socio-cultural, and economic sustainability.This concise exploration aims to provide insights into mitigating environmental pressures in coastal areas, advocating for responsible practices and improved waste management to align Pangandaran's development with long-term sustainability objectives, preserving its natural and cultural assets.

description: In this paper we present a theoretical analysis of the global dynamics in a triaxial galactic system using a 3D integrable Hamiltonian as a simple representation. We include a thorough discussion on the effect of adding a generic non--integrable perturbation to the global dynamics of the system. We adopt the triaxial Stackel Hamiltonian as the integrable model and compute its resonance structure in order to understand its global dynamics when a perturbation is introduced. Also do we take profit of this example in order to provide a theoretical discussion about diffussive processes taking place in phase space.

String Phenomenology and the Cosmological Constant

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It is argued that classical string solutions should not be fine tuned to have a positive cosmological constant (CC) at the observed size, since even the quantum corrections from standard model effects will completely negate any classical string theory solution with such a CC. In fact it is even possible that there is no need at all for any ad hoc uplifting term in the potential since these quantum effects may well take care of this. Correspondingly any calculation of the parameters of the MSSM has to be rethought to take into account the evolution of the CC. This considerably complicates the issue since the initial conditions for RG evolution of these parameters are determined by the final condition on the CC! The Anthropic Principle is of no help in addressing these issues.

description: Four dense cores, L1582A, L1689A, B133 and B68, classified as prestellar in terms of the absence of detectable NIR emission, are observed at radio wavelengths to investigate whether they nurture very young protostars. No definite young protostars were discovered in any of the four cores observed. A few radio sources were discovered close to the observed cores, but these are most likely extragalactic sources or YSOs unrelated to the cores observed. In L1582A we discovered a weak radio source near the centre of the core with radio characteristics and offset from the peak of the submillimeter emission similar to that of the newly discovered protostar in the core L1014, indicating a possible protostellar nature for this source. This needs to be confirmed with near- and/or mid-infrared observations (e.g. with Spitzer). Hence based on the current observations we are unable to confirm unequivocally that L1582A is starless. In L1689A a possible 4.5-sigma radio source was discovered at the centre of the core, but needs to be confirmed with future observations. In B133 a weak radio source, possibly a protostar, was discovered at the edge of the core on a local peak of the core submm emission, but no source was detected at the centre of the core. Thus, B133 is probably starless, but may have a protostar at its edge. In B68 no radio sources were discovered inside or at the edge of the core, and thus B68 is indeed starless. Four more radio sources with spectral indices characteristic of young protostars were discovered outside the cores but within the extended clouds in which these cores reside. Conclusions: We conclude that the number of cores misclassified as prestellar is probably very small and does not significantly alter the estimated lifetime of the prestellar phase.

description: In this paper, we propose a modified susceptible-infected-recovered (SIR) model, in which each node is assigned with an identical capability of active contacts, $A$, at each time step. In contrast to the previous studies, we find that on scale-free networks, the density of the recovered individuals in the present model shows a threshold behavior. We obtain the analytical results using the mean-field theory and find that the threshold value equals 1/A, indicating that the threshold value is independent of the topology of the underlying network. The simulations agree well with the analytic results. Furthermore, we study the time behavior of the epidemic propagation and find a hierarchical dynamics with three plateaus. Once the highly connected hubs are reached, the infection pervades almost the whole network in a progressive cascade across smaller degree classes. Then, after the previously infected hubs are recovered, the disease can only propagate to the class of smallest degree till the infected individuals are all recovered. The present results could be of practical importance in the setup of dynamic control strategies.

description: Euclidean point-to-point propagators or wall-to-wall correlators related to exchange by an unstable particle(sigma,rho,omega-mesons) are modified by presence of particle width. In particular, the usual method of deriving particle masses from logarithmic derivatives need to be modified. Similarly Yukawa-like potentials of nuclear physics due to exchange of those mesons are significantly modified since the coupling to the decay products is strong. For example, the large distance asymptotic changes, exp(-M_{min} r), where M_{min} is the sum of the decay product masses (2 m_π, 2 m_{e}, 2 m_ν). In the area M_{min}r<1the potential has a long-range tail 1/r^3. Similar effects appear due to the virtual decays in the elecroweak sector of the Standard model. The $Z-γ$ mixing via electron loop gives the parity violation potential with the range $1/2 m_{e}$, i.e. the range of the weak interaction increases $10^{5}$ times.

description: Linearized stability of incompressible viscous fluid flows in a thin spherical shell is studied by using the two-dimensional Navier--Stokes equations on a sphere. The stationary flow on the sphere has two singularities (a sink and a source) at the North and South poles of the sphere. We prove analytically for the linearized Navier--Stokes equations that the stationary flow is asymptotically stable. When the spherical layer is truncated between two symmetrical rings, we study eigenvalues of the linearized equations numerically by using power series solutions and show that the stationary flow remains asymptotically stable for all Reynolds numbers.

description: We study the N = 4 theory at weak coupling, on a three sphere in the grand canonical ensemble with R symmetry chemical potentials. We focus attention on near critical values for the chemical potentials, above which the classical theory has no ground state. By computing a one loop effective potential for the light degrees of freedom in this regime, we show the existence of flat directions of complex dimension N, 2N and 3N for one, two and three critical chemical potentials respectively; these correspond to one half, one quarter and one-eighth BPS states becoming light respectively at the critical values. At small finite temperature we show that the chemical potentials can be continued beyond their classical limiting values to yield a deconfined metastable phase with lifetime diverging in the large N limit. Our low temperaure analysis complements the high temperature metastability found by Yamada and Yaffe. The resulting phase diagram at weak coupling bears a striking resemblance to the strong coupling phase diagram for charged AdS black holes. Our analysis also reveals subtle qualitative differences between the two regimes.

description: Οι παράμετροι διεργασίας των laser υπερβραχέων παλμών και η διαχείριση των μοτίβων για το σχηματισμό ηλεκτροδίων σε οργανικά φωτοβολταϊκά (ΟΦΒ) μπορεί να ελεγχθεί αποτελεσματικά με την χρήση του λογισμικό προσομοίωσης LMM,το οποίο έχει αναπτυχθεί στα πλαίσια της παρούσας διπλωματικής εργασίας. Το LMM είναι διαδικτυακό λογισμικό προσομοίωσης για S2S (sheet-to-sheet) εφαρμογή. Είναι εύχρηστο, εύκολα κατανοητό με σύντομους χρόνους απόκρισης, και χωρίς την απαίτηση γνώσης χειρισμού γραφιστικών προγραμμάτων από τον χρήστη. Το LMM είναι βασισμένο σε ASP.NET (C #), και ενσωματώνει την Javascript για τη γραφική απεικόνιση, την HTML και CSS για το σχεδιασμό και τη δομή της ιστοσελίδας. Το LMM προσομοιώνει τη διαδικασία εγχάραξης των μοτίβων που πρόκειται να εγχαραχθούν στο υπόστρωμα με βάση τον τρόπο λειτουργίας του galvo-scanner του laser. Ο χρήστης μπορεί να παρατηρήσει και να αλλάξει τον τρόπο με τον οποίο θα πραγματοποιηθεί η εγχάραξη. Επιπλέον, το LMM δίνει αξιόπιστη (μικρό περιθώριο σφάλματος) προσομοίωση του προφίλ του στίγματος σε ITO και ITO / ZnO εγχαράξεις, με βάση τον τρόπο λειτουργίας του συστήματος laser και τις παραμέτρους που δίνει ο χρήστης. Σε γενικές γραμμές, το LMM είναι μία χρονικά και οικονομικά αποδοτική λύση για την προσομοίωση εγχαράξεων. Η περαιτέρω βελτιστοποίηση του λογισμικού, σε συνδυασμό με την ενσωμάτωση συστήματος mark-recognition, θα μπορούσε να αποτελέσει μία λύση για τον έλεγχο σε μελλοντικές εφαρμογές R2R (roll-to-roll).
description: The ultra-fast laser processing parameters and the manipulation of patterns for organic photovoltaic’s (OPV) electrode formation can be effectively controlled by the LMM simulation software, which have been developed in this thesis. LMM is web-based simulation software for (sheet to sheet) S2S application. It is easy-to-use, self-explanatory with short-time responses, and with no specific user orientation (no necessity of any experience). It is ASP.NET (C#) web-site, and integrates JavaScript for the graphical visualization, HTML&CSS for design and structure of the web page. LMM simulates the patterning process by displaying in animation the laser’s galvo-scanner movements. User can observe and change the way that patterning will be performed. In addition, LMM gives a reliable (being within a small margin of error) spot profile simulation of ITO and ITO/ZnO scribes, by combining the laser-set up working principle with the parameters that user gives. In general, LMM is a time and cost-effective solution for scribing simulation. A further optimization in software, in conjunction with an integration of mark recognition set-up, would be an optimal solution for the control of the future R2R (roll-to-roll) applications.

description: TeV gamma-ray emission from two massive binaries of the microquasar type, LS 5039 and LS I +61$^{\rm o}$ 303, show clear variability with their orbital periods. Our purpose is to calculate the GeV and TeV $γ$-ray light curves from the massive binary LS 5039 which are expected in the specific Inverse Compton $e^\pm$ pair cascade model. This model successfully predicted the basic features of the high energy $γ$-ray emission from LS 5039 and LS I +61 303. In the calculations we apply the Monte Carlo code which follows the IC $e^\pm$ pair cascade in the anisotropic radiation of the massive star. The $γ$-ray light curves and spectra are obtained for different parameters of the acceleration scenario and the inclination angles of the binary system. It is found that the GeV and TeV $γ$-ray light curves should be anti-correlated. This feature can be tested in the near future by the simultaneous observations of LS 5039 with the AGILE and GLAST telescopes in GeV energies and the Cherenkov telescopes in the TeV energies. Considered model also predicts a broad maximum in the TeV $γ$-ray light curve between the phases $\sim 0.4-0.8$ consistently with the observations of LS 5039 by the HESS telescopes. Moreover, we predict additional dip in the TeV light curve for large inclination angles $\sim 60^{\rm o}$. This feature could serve as a diagnostic for independent measuring of the inclination angle of this binary system indicating also on the presence of a neutron star in LS 5039.

Central American refugee claimants’ experiences accessing health care

description: Recent Canada Employment and Immigration Commission statistics indicate that individuals from Central America continue to claim refugee status at B. C. port-of-entry. No studies have been conducted examining Central American refugee claimants' experiences when trying to access health care services. The purpose of this study, therefore, was to examine from the perspective of the refugee claimants, their experiences accessing health care services in Vancouver. A conceptual framework developed by this researcher guided the analysis of the data whereby macro political, economic and social domains were depicted as influencing refugee claimants' every day psychosocial/economic realities, their health care seeking experiences and their health status. The policies of the political domain also influenced the health care institutional level. The research method for this study was a phenomenological approach. Data for the study were derived from unstructured audiotaped interviews conducted by this researcher with the assistance of simultaneous translation by a translator. Interviews with 9 Central Americans, who described their experiences accessing health care, were 50 to 135 minutes long. Participants shared information of their past and present realities which provided a contextual basis for understanding their experiences. The audiotapes of the interviews were transcribed verbatim and were analyzed for emerging concepts and themes. Each concept was comprised of several themes. The three main concepts that evolved from the data analysis were marginality, health care seeking experiences and the illness experience. These concepts were interpreted in relation to the study's conceptual framework. Fear and suffering, along with unemployment, loss and isolation, and discrimination, are themes reflecting past and present influence on participants' marginality. Participants' health care seeking experiences are understood within this "marginal" context. Health policy and associated bureaucratic processes shaped participants' health care seeking patterns and what transpired at the healthcare institutional level. Difficulty accessing medical coverage and or comprehensive medical care had repercussions on participants' illness experiences. A number of recommendations have been made that address health policy, nursing practice, education, research, administration and professional associations.

Ο περιορισμός, ωστόσο, της κρατικής κυριαρχίας δεν κατάφερε να φτάσει στο σημείο του περιορισμού της κρατικής ασυλίας σε περιπτώσεις παραβίασεις των πιο θεμελιωδών ανθρωπίνων δικαιωμάτων και αξιών της διεθνούς κοινότητας. Στο πλαίσιο αυτό διερευνάται αρχικά η δομική αλληλεπίδραση των κανόνων ius cogens και της κρατικής ασυλίας και διακρίνονται τρεις προσεγγίσεις, εκείνη της κανονιστικής ιεραρχίας, της πρακτικής εναρμόνισης των κανόνων δικαίου, της τυπικής ερμηνείας και του περιορισμού του πεδίου εφαρμογής των κανόνων ius cogens. Στη συνέχεια, διερευνάται η επίδραση της κρατικής ασυλίας στο δικαίωμα πρόσβασης στη δικαιοσύνη και την αποτελεσματική προσφυγή. Τέλος, υπό το φως των παραπάνω παραδοχών εξετάζεται η απόφαση του Δικαστηρίου της Χάγης στην Υπόθεση των Δικαιοδοτικών Ασυλιών του Κράτους.
description: During the course of 20th century the necessity of institutionally organizing the International Community under the rule of law, of safeguarding its fundamental values and protecting the Person within it, have marked the transition from State-centrism to Humanism. However, the restriction of state sovereignty has not managed to reach the point of limiting State Immunity in cases of breach of the most fundamental Human Rights and values of the International Community. In this context, we first examine the structural interaction of ius cogens rules and State Immunity and distinguish three different cases; the approach of the normative hierarchy theory, the interpretation made in accordance with the applicable rules of international law, the typical interpretation theory, and the limitation of the normative scope of ius cogens. Subsequently, we examine the effect of State Immunity on the right of access to a Court, as well as on the right to an effective remedy. Finally, in the light of the assumptions made above, we examine the decision of the International Court of Justice on the case of the Jurisdictional Immunities of the State (2012).

description: We present the Pre-Main-Sequence (PMS) evolutionary tracks of stars with 0.0065~5.0Ms. The models were evolved from the PMS stellar birthline to the onset of hydrogen burning in the core. The convective turnover timescales which enables an observational test of theoretical model, particulary in the stellar dynamic activity, are also calculated. All models have Sun-like metal abundances, typically considered as the stars in the Galactic disk and the star formation region of Population I star. The convection phenomenon is treated by the usual mixing length approximation. All evolutionary tracks are available upon request.

description: We analyze Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) data of the transient low mass X-ray binary (LMXB) system 1A 1744-361. We explore the X-ray intensity and spectral evolution of the source, perform timing analysis, and find that 1A 1744-361 shows `atoll' behavior during the outbursts. The color-color diagram indicates that this LMXB was observed in a low intensity spectrally hard (low-hard) state and in a high intensity `banana' state. The low-hard state shows a horizontal pattern in the color-color diagram, and the previously reported `dipper QPO' appears only during this state. We also perform energy spectral analyses, and report the first detection of broad iron emission line and iron absorption edge from 1A 1744-361.
