The effect of optical injection on the gain and high frequency performance of AlGaAs/GaAs heterojunction bipolar transistor
Creators: name: Lee, Chia-Nan
Publisher: name: University of British Columbia
Year: 2009

description: A comprehensive, one-dimensional, analytical model of the graded-base AlGaAs/GaAs heterojunction bipolar transistor is presented, and used to examine the influence of optical injection on the DC and high-frequency performance of a device with a conventional pyramidal structure. Absorption is limited to the base and collector regions because of the window effect of the wider bandgap emitter. Grading is considered by varying the A l mole fraction x linearly across the base to a value of zero at the base-collector boundary. Recombination in the space-charge and neutral regions of the device is modeled by considering Shockley-Read-Hall, Auger and radiative processes. Experimental devices were obtained from the Communications Research Centre, Ottawa and packaged by the author at the Alberta Microelectronics Centre and the Telecommunications Research Laboratory, Edmonton. The packaged devices were tested to evaluate the DC and high-frequency performances. Comparisons between predictions of the model and experimental data from a packaged device are presented. Optical injection is observed to improve the DC and high-frequency characteristics of the device.

description: We study instanton solutions and superpotentials for the large number of vacua of the plane-wave matrix model and a 2+1 dimensional Super Yang-Mills theory on $R\times S^2$ with sixteen supercharges. We get the superpotential in the weak coupling limit from the gauge theory description. We study the gravity description of these instantons. Perturbatively with respect to a background, they are Euclidean branes wrapping cycles in the dual gravity background. Moreover, the superpotential can be given by the energy of the electric charge system characterizing each vacuum. These charges are interpreted as the eigenvalues of matrices from a reduction for the 1/8 BPS sector of the gauge theories. We also discuss qualitatively the emergence of the extra spatial dimensions appeared on the gravity side.

description: Τα αποθέματα αποτελούν πλέον ένα από τα πιο σημαντικά στοιχεία μιας επιχείρησης. Η κατάλληλη διαχείρισή τους μπορεί να οδηγήσει σε βελτίωση της εξυπηρέτησης των πελατών της, ανεξαρτητοποίηση της παραγωγικής διαδικασίας και μείωση του κόστους της. Από την άλλη πλευρά, η εκτίμηση της μελλοντικής κατάστασης μιας επιχείρησης, μέσω της διαδικασίας της πρόβλεψης, είναι εξίσου σημαντική και απαραίτητη για τη βιωσιμότητα και την ευημερία της. Ο βασικός λόγος είναι ότι μέσω της πρόβλεψης μειώνεται το επίπεδο αβεβαιότητας, με αποτέλεσμα η επιχείρηση να οδηγείται στη λήψη καταλληλότερων αποφάσεων. Στόχος της παρούσας εργασίας είναι η παρουσίαση σημαντικών, σύνθετων και απλών, υποδειγμάτων διαχείρισης αποθεμάτων και πρόβλεψης και η εφαρμογή τους μέσα από το περιβάλλον του Microsoft Excel. Η παρούσα εργασία μελετά τα χαρακτηριστικά γνωρίσματα των πιο γνωστών υποδειγμάτων διαχείρισης αποθεμάτων και πρόβλεψης, εστιάζοντας σε επιλεγμένα υποδείγματα που ξεχωρίζουν. Ειδικότερα, όσον αφορά στη διαχείριση αποθεμάτων αναλύονται τα υποδείγματα μιας περιόδου, βασικού αποθέματος και (Q, r) ενώ επίσης παρουσιάζονται υποδείγματα διαχείρισης πολλαπλών προϊόντων και ένα υπόδειγμα διαχείρισης αποθέματος εφοδιαστικής αλυσίδας. Όσον αφορά στο κομμάτι της πρόβλεψης, η εργασία εστιάζει στην ανάλυση 2 υποδειγμάτων που αφορούν στην πρόβλεψη ζήτησης νέων προϊόντων, το υπόδειγμα Bass και το υπόδειγμα πρόβλεψης ανταλλακτικών νέων προϊόντων. Επιπλέον, η εργασία περιέχει 2 Παραρτήματα, όπου παρουσιάζονται και εφαρμόζονται τα βασικά υποδείγματα διαχείρισης αποθεμάτων και πρόβλεψης.
description: Inventory has become one of the most important assets of a business. A good inventory management policy may result to customer service improvement, production process decoupling and cost reduction. On the other hand, estimation of the future conditions via forecasting is equally important and essential for a business’s viability and prosperity. The key reason is that an efficient forecasting process decreases the level of uncertainty and as a result, the business is able to make the right decision. This paper aims to present important, complex and simple inventory management and forecasting models and implement them into Microsoft Excel environment. In other words, this paper examines the characteristics of the most known inventory management and forecasting models, while focusing on selected model that stand out. Specifically, there is an analysis of base stock model and (Q, r) model. This paper also deals with inventory management models for multi-products and multi-echelon supply chain. As regards forecasting models, the paper focuses on 2 models related to forecasting demand of new products, Bass model and New Product Spares Forecast model. In addition, this paper includes 2 Appendices that contain the presentation and the implementation of basic inventory management and forecasting models.

description: We use HST NICMOS continuum and Pa-alpha observations to study the near-infrared and star-formation properties of a representative sample of 30 local (d ~ 35-75Mpc) luminous infrared galaxies (LIRGs, infrared 8-1000um luminosities of L_IR=11-11.9[Lsun]). The data provide spatial resolutions of 25-50pc and cover the central ~3.3-7.1kpc regions of these galaxies. About half of the LIRGs show compact (~1-2kpc) Pa-alpha emission with a high surface brightness in the form of nuclear emission, rings, and mini-spirals. The rest of the sample show Pa-alpha emission along the disk and the spiral arms extending over scales of 3-7kpc and larger. About half of the sample contains HII regions with H-alpha luminosities significantly higher than those observed in normal galaxies. There is a linear empirical relationship between the mid-IR 24um and hydrogen recombination (extinction-corrected Pa-alpha) luminosity for these LIRGs, and the HII regions in the central part of M51. This relation holds over more than four decades in luminosity suggesting that the mid-IR emission is a good tracer of the star formation rate (SFR). Analogous to the widely used relation between the SFR and total IR luminosity of Kennicutt (1998), we derive an empirical calibration of the SFR in terms of the monochromatic 24um luminosity that can be used for luminous, dusty galaxies.

description: The aim of the present thesis is the pursuit of the justification of the existence of the mitigating circumstance of the article 84§2a of the greek penal code in light of the nature of the mitigating circumstances. In the first part, it is underlined that the justification of the existence of the mitigating circumstances has to be searched in the field of the penalty and more specifically, it has to be connected with the purposes of criminal punishment, while it is attempted the establishment of the concept of the former honest life with references to jurisprudence of the greek penal courts. In the second part, through the comparative study of the mitigating circumstances, based on their connection with the act and the purposes of the criminal punishment, is featured the relation of the mitigating circumstances of the article 84§2b and c of the greek penal code with the retribution and those of the article 84§2a, d and e of the greek penal code with the specific deterrence. Finally, in the third part, on the one hand is highlighted the practical significance of the delimitation of the nature of the mitigating circumstance of the article 84§2a of the greek penal code, on the other hand are underlined some general conclusions drawn from the study that preceded.

description: The purpose of the research presented here is to investigate students' understanding the layering and composition of the interior of the earth. We also wanted find out whether the theoretical framework of conceptual change developed by Vosniadou and Brewer (Vosniadou -Brewer. 1992) can be used to explain the students' responses. 120 students in first, fourth, sixth, eleventh grade, as well as University undergraduate’s students in Primary education was used in οour results show that the younger children seem to believe that the earth's interior consists of simple, solid material in a flat arrangement. The representation of earth's interior which was more common in the drawings of the oldest students was that of magma in the low strata of the earth in flat arrangement or that of magma in the core of the earth in spherical arrangement, The category which was close to scientific one, was that of magma in the core of the earth and in the area οur research support the Vosniadou and Brewer (1992) proposal that the children from an initial explanatory framework which changes, in a gradual way .The results also show there is a sequence in the understanding of certain key ideas related to the layering and composition of the earth. For example, it appears that children mast understand the spherical shape of the earth before representing the inside of the earth in spherical layers and must acquire an understanding of gravity before they place the magma in the center of the earth. The above results should be taken into account in the planning of curricula and instructor for elementary and high school classes.

Inertial effects in B{ü}ttiker-Landauer Motor and Refrigerator at the Overdamped Limit

Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We investigate the energetics of a Brownian motor driven by position dependent temperature, commonly known as the B{ü}ttiker-Landauer motor. Overdamped models (M=0) predict that the motor can attain Carnot efficiency. However, the overdamped limit ($M\to 0$), contradicts the previous prediction due to the kinetic energy contribution to the heat transfer. Using molecular dynamics simulation and numerical solution of the inertial Langevin equation, we confirm that the motor can never achieve Carnot efficiency and verify that the heat flow via kinetic energy diverges as $M^{-1/2}$ in the overdamped limit. The reciprocal process of the motor, namely the B{ü}ttiker-Landauer refrigerator is also examined. In this case, the overdamped approach succeeds in predicting the heat transfer only when there is no temperature gradient. Its found that the Onsager symmetry between the motor and refrigerator does not suffer from the singular behavior of the kinetic energy contribution.

description: The paper uses five comparative tools (the theories of functionalism and conflict, the theoretical frameworks of modernity and post modernity, the contemporary international discourse on educational reform, the rationale of recent major educational reforms in Anglo - American Democracies, and the OECD 1995 Critical Survey on Education in Greece) to try to uncover the identity of the 1997 major Greek education reform "Education 2000 - For an Education of Open Horizons". The comparison shows that the Greek reform is to a great extent governed by functionalist and modern (rather than postmodern) ideas and that it diverges substantially from the major reforms in USA, Canada and UK. It also shows that the reform has failed to take notice of some major recommendations set forth by the OECD Survey concerning the need for educational decentralization and school autonomy. The paper explains these divergences as the result of fundamental characteristics of Greek society, the substantial legitimacy deficits of the modern Greek state, and the traditional big power of teacher trade unions in Greece. The paper concludes that unless these characteristics are modified there is little chance for educational reforms to succeed in Greece.

Inelastic Neutrino-Helium Scatterings and Standing Accretion Shock Instability in Core-Collapse Supernovae

description: We present the results of numerical experiments, in which we have investigated the influence of the inelastic neutrino-helium interactions on the standing accretion shock instability supposed to occur in the post-bounce supernova core. The axisymmetric hydrodynamical simulations of accretion flows through the standing accretion shock wave onto the protoneutron star show that the interactions are relatively minor and the linear growth of the shock instability is hardly affected. The extra heating given by the inelastic reactions becomes important for the shock revival after the instability enters the non-linear regime, but only when the neutrino luminosity is very close to the critical value, at which the shock would be revived without the interactions. We have also studied the dependence of the results on the initial amplitudes of perturbation and the temperatures of mu and tau neutrinos.

description: Zur Beschreibung des Implementierungsfortschritts bei der Anwendung von Building Information Modeling (BIM) innerhalb eines Projekts oder Unternehmens können Reifegradmodelle verwendet werden. Eine der bekanntesten Einteilungen sind die sogenannten BIM Level aus Großbritannien. Allerdings finden sich in der Literatur viele weitere Modelle, die teilweise präziser differenzieren und umfassendere Bewertungskriterien heranziehen. Die große Anzahl erschwert die Auswahl geeigneter Modelle für ein bestimmtes Unternehmen oder Projekt. Dabei ist es wichtig, den Reifegrad der Anwendung von BIM zu bestimmen, da die Anzahl potentiell umsetzbarer BIM-Anwendungsfälle (AWF) mit zunehmendem Reifegrad wächst. Dieser Beitrag identifiziert daher zunächst bestehende Reifegradmodelle. Aufbauend auf einer tiefergehenden Beschreibung und Analyse erfolgt abschließend ein bewerteter Vergleich der Modelle.

GrafTab: an innovative requirements specification method for a PLC system
Creators: name: So, So-Ming
Publisher: name: University of British Columbia
Year: 2009

description: The flexibility and intelligence of Programmable Logic Controllers (PLCs) has. been improved tremendously since their first appearance in 1968. Today, PLC applications range from food production to nuclear plant operation. As the applications become more complicated, the use of informal English as a medium to write the requirements specification for these PLC systems is no longer adequate or satisfactory. A new semi-formal specification method, GrafTab, is introduced in this thesis. It is characterized by a graphical and tabular description method. A complete requirements specification in GrafTab consists of a system abstract, a monitored and controlled variable specification, an external interface document, and a system requirements document. GrafTab, is a powerful method that offers an unambiguous, complete, and readable requirements specification document. Since each document in GrafTab possesses a formal syntax, mechanisms for transforming a GrafTab specification into two executable programs (ladder diagram and SFC) are developed as well. A method to analyze the performance of these programs directly from the specification is included in this thesis.

description: Η εποχή μας έχει την τάση να θεωρεί τα ψυχολογικά προβλήματα του κάθε ανθρώπου ξεχωριστά και ν' απαιτεί για την αντιμετώπιση τους τη στροφή προς την ψυχανάλυση και την ψυχιατρική, που προσπαθούν κυρίως για την υπέρβαση της ατομικής κρίσεως και ενοχής. Η χριστιανική - ορθόδοξη πνευματικότητα καλείται να μαρτυρήσει ότι τα πραγματικά προβλήματα του ανθρώπου είναι πνευματικά, δηλαδή καταρχήν προσωπικά με την έννοια του προσώπου. Ως προσωπικά στη συνέχεια εντάσσονται στην καθολική διάσταση της υπάρξεως, στην καθολικότητα και κοινωνικότητα του ανθρώπου, με μια λέξη, στην αγάπη, όπου ολοκληρώνουν το νόημά τους η προσωπικότητα και η πνευματικότητα. Οι διαφοροποιήσεις στην ανθρωπολογία μεταξύ των κοσμικών αντιλήψεων είτε πρόκειται για την ψυχιατρική, είτε πρόκειται για τις διάφορες ψυχολογικές θεωρίες, αποτελούν όντως ουσιαστικό ζήτημα και επηρεάζουν τον τρόπο κατανόησης και αντιμετώπισης των ψυχικών ασθενειών. Άποψη μας όμως είναι πως μπορούν και είναι αναγκαίο να βρεθούν σημεία επικοινωνίας για την καλύτερη διαποίμανση του πληρώματος της Εκκλησίας. Στο πλαίσιο αυτό στο παρόν πόνημα γίνεται προσπάθεια να παρατεθούν και να βρεθούν τα κοινά σημεία των διαφορετικών θέσεων. Ξεκινώντας από τις βασικές έννοιες της ανθρωπολογίας όπως το σώμα, η ψυχή και περνώντας στις πιο σύνθετες όπως η ψυχική νόσος και οι θεραπείες της γίνεται προσπάθεια να αναγνωριστούν οι διαφορές και να συντεθούν όσο αυτό είναι δυνατόν.
description: In our days psychological problems are considered individually and are attributed mainly to biological reasons. Even psychotherapies, like psychoanalysis are concerned with personal guilt and anxiety not having a holistic approach of every patient. Orthodox Christian tradition is based on the concept of «πρόσωπο» which considers every person as a part of a community and its psychological problems in the light of its relation with God. Love and communication (in the Orthodox sense) are vital for a healthy and complete life. In this study at first, we are trying to present the different concepts of the medical/ psychological and the Orthodox way. Body, soul, psychiatric illnesses are discussed and a common ground is presented in order to help the pastoral work of the Church.

description: Motivated by the prospect of optical lattice experiments with two-component Fermi gases consisting of different atomic species such as Li and K, we calculate the energies for N fermions under harmonic confinement as a function of the mass- and trap-imbalance, i.e., as a function of the ratio between the masses and frequencies of species one and two, using microscopic approaches. Our energies for N=2 through 6 can be used to determine the energetically most favorable configuration for a given number of atoms per species of a deep lattice in which each lattice site is approximately harmonic and in which tunneling between neighboring sites can be neglected. Furthermore, our energies determine one of the input parameters, namely the onsite interaction strength, of the corresponding lattice Hamiltonian.

description: Η παρούσα μεταπτυχιακή διατριβή στοχεύει στη δημιουργία ενός νέου τόπου συζήτησης και εμπλοκής των επιστημών της Αρχιτεκτονικής Τοπίου, της Παιδαγωγικής, της Ψυχολογίας και της Γεωγραφίας. Το ερευνητικό ερώτημα της εργασίας συμπυκνώνεται στην αναζήτηση των προσεγγίσεων μέσω των οποίων μπορούν να συσχετιστούν ο σχεδιασμός υπαίθριων χώρων για παιδιά με την εύρεση της παιδαγωγικής ποιότητας και αξίας του τοπίου. Η θεωρητική κίνηση της εργασίας στηρίζεται κατά βάση στο μεταδομισμό με κάποιες αναφορές, κυρίως συγκριτικές, σε προγενέστερα ρεύματα όπως αυτά της φαινομενολογίας και του μοντέρνου. Η δομή της έρευνας ξεκινά με μία βιβλιογραφική διερεύνηση και συνεχίζει με τη βιωματική αφήγηση σύγχρονων εφαρμοσμένων παραδειγμάτων χώρων για παιδιά. Στα παραδείγματα αυτά αναζητάται η υλικότητα, οι τεχνικές σχεδίασης καθώς και η διαδικασία παραγωγής τους και εξετάζεται εάν και κατά πόσο προκαλούν τα παιδιά να βιώσουν το τοπίο. Συμπεραίνουμε ότι μέσω της διεπιστημονικής συνεργασίας μπορούμε να δημιουργήσουμε μία νέα συνθήκη διαλόγου και δημιουργίας όπου παιδί και τοπίο θα συντεθούν σε κάτι νέο που θα ωφελήσει την αρχή της κάθε κοινωνίας, το παιδί.
description: This Master thesis aims to create a new place for discussion and engagement between the Sciences of Landscape Architecture, Pedagogy, Psychology and Geography. The approaches that can relate the design of outdoor spaces for children and the pedagogical quality and value of space create the hypothesis of this research. This project is based mostly on the post-structuralism theory while moving through earlier movements for comparison such as phenomenology and modern movement. The structure of the thesis begins with a literature review and continues with an experiential narration of contemporary examples of outdoor spaces for children. The materiality, the design techniques as well as the design process of these examples are being investigated to determine if they are capable of triggering children to explore and experience the space. To conclude, we could create a new dialogue and the conditions through interdisciplinary cooperation where the child and the landscape can be synthesized into something new that could benefit the principle of every society, the child.

description: We study the security of the information transmission between two honest parties realized through a lossy bosonic memory channel when losses are captured by a dishonest party. We then show that entangled inputs can enhance the private information of such a channel, which however does never overcome that of unentangled inputs in absence of memory.

description: This paper discusses the extended autonomy that schools were given in USA, England, Australia and New Zealand as a par: of the establishment of quasi markets in the education of these countries as well as the impact of those changes in the European Union member-states. The main focus of the analysis is the stats control of the education systems of the countries under consideration. On the basis of the evidence brought, the paper dismisses the claim that those reforms signify a retreat of the state from its traditional role of controlling education provision. It is suggested instead that the changes in the four countries should be seen in the framework of the state restructuring induced by wider economic pressures at the end of the 20"' century. The paper finally points to the emergence of an 'Anglo-Saxon mode of state control which combines goal-oriented oriented regulation with school autonomy and consists of an application of the newest corporate management strategies.

Για το λόγο αυτό δημιουργήθηκαν δύο ομάδες, μαθητών με Μαθησιακές Δυσκολίες και τυπικών μαθητών, από τους οποίους προέκυψαν και οι γραπτές παραγωγές. Στη συνέχεια διορθώθηκαν τα λάθη που παρήγαν στο γραπτό τους λόγο με εξειδικευμένο εργαλείο διόρθωσης λαθών και αναλύθηκαν (ανάλυση λαθών- miscue analysis). Η ανάλυση αυτή αρχικά, ανέδειξε τα κυρίαρχα λάθη του γραπτού λόγου της αρχικής και τελικής αξιολόγησης και στη συνέχεια, μπορέσαμε να δούμε αν υπάρχουν αλλαγές στα λάθη των μαθητών πριν και μετά την εκπαιδευτική παρέμβαση. Τέλος, αναδείχθηκαν τα κυρίαρχα λάθη των μαθητών με και χωρίς Μαθησιακές Δυσκολίες και γλώσσα καταγωγής τη ρωσική και διαμορφώθηκε το προφίλ του γραπτού λόγου των μαθητών με Μαθησιακές Δυσκολίες.
description: The purpose of this research was to outline the profile of the written language of students with Specific Learning Difficulties and Russian as their mother tongue. Two groups have been formed for this reason, that is, students with learning difficulties and typical students, of whom the written production emerged. The errors in their writing production were then corrected with a specialized debugging tool and analyzed (miscue analysis). This analysis firstly showed the dominant errors of the students during the initial and final evaluation. We were then able to spot any changes in the students’ mistakes before and after the educational intervention. Finally, the dominant mistakes of students with and without learning difficulties and Russian as mother tongue were highlighted and thus the profile of the written language of students with Learning Difficulties was formed.

description: Within the framework of the Landau-Ginzburg-Devonshire approach we explore the impact of elastic anisotropy, electrostriction, flexoelectric couplings, and mismatch strain on the domain structure morphology in ferroelectric core-shell nanoparticles of spherical shape. We perform finite element modelling (FEM) for multiaxial ferroelectric nanoparticle cores covered with an elastically-isotropic soft or elastically-anisotropic rigid paraelectric shell, with and without mismatch strains. In the case of a core covered with a soft shell, the FEM results show that at room temperature a single polarization vortex with a dipolar kernel can be stable if the electrostriction coupling is weak. With increasing anisotropic electrostriction coupling, the vortex disappears and is replaced by complex flux-closure structures, which are formed in the equatorial plane and transform into an elongated vortex with a central 180-degree domain wall near the core poles. This complex domain morphology develops in the core due to the anisotropic electrostriction, and the flexoelectric coupling leads to an additional curvature and twist of the polarization isosurfaces. In contrast to this, FEM performed for a core covered with a rigid shell shows that, at room temperature, the anisotropic elastic properties of the shell can stabilize vortex-like structures with three flux-closure domains, which gradually cross in the equatorial plane of the core and transform into 120-degree domains near the core poles. The flexoelectric coupling leads to a noticeable curling of the flux-closure domain walls. A mismatch strain compensates the curling of the flux-closure domains in the core confined by the elastically-anisotropic rigid shell. Our analysis reveals different types of topological defects, namely Bloch point structures (BPS) and Ising lines, that form in a ferroelectric core covered with a soft or rigid shell.

description: Στην παρούσα εργασία εξετάσαμε το ζήτημα της αναγνώρισης κυβερνήσεων και της άρσης της αναγνώρησης κυβερνήσεων. Η αναγνώριση αποτελεί ένα σύνθετο ζήτημα. Αρχικά, εξετάσαμε τις διαφορετικές ερμηνείες που έχει η έννοια της αναγνώρισης κυβερνήσεων. Σε επόμενο στάδιο, αναλύσαμε τα διάφορα είδη της αναγνώρισης κυβερνήσεων, κυρίως την de jure αναγνώριση και την de facto αναγνώριση, αλλά και άλλες παραλλαγές της. Στη συνέχεια, προσπαθήσαμε να αναδείξουμε το minimum των κριτηρίων που πρέπει να πληροί μια αρχή για την αναγνώριση της ως κυβέρνησης, τα κριτήρια που μπορούμε να αντλήσουμε από το διεθνές δίκαιο για την αναγνώριση κυβέρνησης. Σκιαγραφήσαμε τον τρόπο με τον οποίο το jus cogens και οι διεθνείς υποχρεώσεις erga omnes καθορίζουν το νομικό πλαίσιο που επηρεάζει αποφασιστικά τις πολιτικές αναγνώρισης των κυβερνήσεων. Επιπρόσθετα, αναφερθήκαμε στον τρόπο με τον οποίο η διεθνής προστασία των ανθρώπινων δικαιωμάτων επηρεάζει τις διάφορες πολιτικές αναγνώρισης και εξετάσαμε αν η αρχή της δημοκρατικής νομιμότητας αποτελεί προυπόθεση για την αναγνώριση μιας αρχής ως κυβέρνησης, στα πλαίσια του διεθνούς δικαίου. Τέλος, εξάγαμε κάποια χρήσιμα συμπεράσματα.
description: In this thesis we examined the issue of recognition and derecognition of governments. Recognition is a complicated issue. First, we examined the different meanings of the term. Next, we analyzed the several variants of recognition of governments, mainly de jure recognition and de facto recognition, and other variations. Furthermore, we tried to establish the minimum criteria for the recognition of an authority as a government, the criteria for the status of government laid down by international law. We delineated the way jus cogens and international obligations erga omnes determine the legal framework that affects crucially the recognition policies of the governments. Additionally, we made reference to the way international protection of human rights affects the recognition policies and we examined if the principal of democratic legitimacy is a requirement for the recognition of an authority as a government, in the sense of international law. Finally, we drew some useful conclusions.

description: Public awareness on perceiving religious dialogue as a determinant of conflict prevention and social peace building in intercultural and multi-religious societies is increasing day by day. For a long time, the debate over religion was characterized by the idea that the increasing secularism of Western societies would lead to a gradual withdrawal of religion from public space. However, the last decade, returned religion in public discussion as a determinant of peace building. Regardless of the variety of how this discussion unfolds in European countries, the study of the impact of "religion" on intercultural dialogue and on tensions and social conflicts seems to be becoming increasingly important. Meanwhile education and religious education is an important element for shaping the critical skills of future citizens, for intercultural dialogue and for peace building as well.

This research focuses on assessing the peace building contribution of religious education in Albaniaa multi religious society, in two different periods of time, the pre-communist era and the post-communist regime. An explorative research methodology is implemented to achieve this aim through collecting primary and secondary data. Documents and studies in the field of religious education were collected from Central State Archive for the pre-communist period and data from the current schools of different religious communities in Albania were evaluated.

The study brings to attention the Albanian case, where religious education had in the past and has currently a decisive impact on peace building. Religious communities have dozens of schools and 4 universities, where thousands of students’ study and their graduates constitute a vital part of the society. Education plays an essential role in intercultural understanding, in favour of coexistence and tolerance and the contribution of these schools to society is enormous asthey are strengthening interfaith dialogue and its transmission to young people. In addition to the collaboration between the three theologies, cooperation is also increasing between universities, which despite being founded by religious communities, have in general and other secular departments of various academic fields.

description: Aspect mining is a reverse engineering process that aims at finding crosscutting concerns in existing systems. This paper proposes an aspect mining approach based on determining methods that are called from many different places, and hence have a high fan-in, which can be seen as a symptom of crosscutting functionality. The approach is semi-automatic, and consists of three steps: metric calculation, method filtering, and call site analysis. Carrying out these steps is an interactive process supported by an Eclipse plug-in called FINT. Fan-in analysis has been applied to three open source Java systems, totaling around 200,000 lines of code. The most interesting concerns identified are discussed in detail, which includes several concerns not previously discussed in the aspect-oriented literature. The results show that a significant number of crosscutting concerns can be recognized using fan-in analysis, and each of the three steps can be supported by tools.

description: Understanding the relationship between the underlying escape fraction of Lyman continuum (LyC) photons ($f_{\rm esc}$) emitted by galaxies and measuring the distribution of observed $f_{\rm esc}$ values at high redshift is fundamental to the interpretation of the reionization process. In this paper we perform a statistical exploration of the attenuation of LyC photons by neutral hydrogen in the intergalactic medium using ensembles of simulated transmission functions. We show that LyC detected galaxies are more likely to be found in sightlines with higher-than-average transmission of LyC photons. This means that adopting a mean transmission at a given redshift leads to an overestimate of the true $f_{\rm esc}$ for LyC detected galaxies. We note, however, that mean values are appropriate for $f_{\rm esc}$ estimates of larger parent samples that include LyC non-detected galaxies. We quantify this IGM transmission bias for LyC detections in photometric and spectroscopic surveys in the literature and show that the bias is stronger for both shallower observations and for fainter parent samples (i.e. Lyman $α$ emitters versus Lyman break galaxies). We also explore the effects of varying the underlying probability distribution function (PDF) of $f_{\rm esc}$ on recovered values, showing that the underlying $f_{\rm esc}$ PDF may depend on sample selection by comparing with observational surveys. This work represents a first step in improved interpretation of LyC detections in the context of understanding $f_{\rm esc}$ from high redshift galaxies.
