description: Το διάστημα 1960-1974 είναι κρίσιμο για το κυπριακό θέατρο. Η θεατρική δραστηριότητα είναι έντονη(πολλοί θίασοι δημιουργούνται και διαλύονται, παρουσιάζονται διαφορετικά είδη θεάτρου), το επαγγελματικό θέατρο εδραιώνεται και αρχίζει να ωριμάζει και τέλος, ιδρύεται κρατικό θέατρο. Το 1961 ιδρύεται με ιδιωτική πρωτοβουλία, ο Οργανισμός Θεατρικής Ανάπτυξης Κύπρου, θίασος που έχει μέχρι το τέλος του 1963 τη μερική στήριξη της πολιτείας. Ο θίασος επιβιώνει μέχρι το 1968. Σημαντική είναι η παρουσία του Θεάτρου Τέχνης(1961-1962), όπως και των θιάσων που ίδρυσαν οι σκηνοθέτες Βλ. Καυκαρίδης και Ν. Σιαφκάλης. Το 1969 το ΡΙΚ προχωρεί στην ίδρυση θιάσου, ο οποίος εργάζεται με τους καλύτερους μέχρι τότε όρους, φέρνοντας μια νέα πνοή ως προς την καλλιτεχνική αρτιότητα των παραστάσεων. Το 1971 με την ίδρυση του ΘΟΚ, η πολιτεία δίνει μια απάντηση στο επίμονο αίτημα του πνευματικού και καλλιτεχνικού κόσμου για την κρατική αρωγή στη θεατρική δραστηριότητα, ενώ από το 1969 το Υπ. Παιδείας επιχορηγεί τους θιάσους με μικρά ποσά. Παράλληλα με τον ΘΟΚ, λειτουργεί στο διάστημα 1972-1974 η ευέλικτη και τολμηρή Πειραματική Σκηνή
description: The years 1960-1974 are crucial for the theatre of Cyprus. There is an intensive theatre activity(there are a lot of companies, most of the short-lived, who present different kinds of theatre), professional theatre is gradually established and finally the state theatre is founded. In 1961 the OTHAK is created after an initiative of citizens. The company will be supported by the state for a couple of years. OTHAK exists until 1968. Theatro Technis(1961-1962) is also an importantcompany. Important are the proposals of the director Vlademiros Kafkarides and Nicos Shiafkalis, through the companies the created. In 1969 RIK(CBS) creates its house company, which works under the best terms ever for the Cyprus theatre and revitilizes the theatre activity by presenting elaborate shows. In 1971 the state gives an answer to the demand of artists and scholars for contribution to theatre by founding THOK. In the meanwhile, since 1969, the ministry of education supports most companies with small amounts. During the years 1972-1974 Peiramatiki Skini constitutes an alternative to THOK, being more flexible and experimental

description: Η παρούσα διατριβή έχει αντικείμενο τη μελέτη του μοναστικού τύπου των ησυχαστηρίων. Τα ησυχαστήρια είναι κοινοβιακές μονές ιδιωτικού δικαίου και έχουν μέλη αφιερωμένα στο Θεό. Ιδρύονται ως ιδρύματα σύμφωνα με τις διατάξεις του κοινού δικαίου, άρθρα 108-121Α.Κ. Πρόκειται για δικαιϊκό θεσμό που εμφανίστηκε τα τελευταία χρόνια και διέπεται από δίκαιο αναγκαστικό, τις πολιτειακές διατάξεις που ρυθμίζουν τα θέματα του μοναχισμού και το κανονικό δίκαιο της Ορθόδοξης Εκκλησίας. Δεν αναγνωρίζεται δηλ. προνομιακό καθεστώς για τη διοίκηση και διαχείρισή τους. Τα μέλη τους προσλαμβάνοντας τη μοναστική ιδιότητα περιέρχονται σε ειδικό νομικό καθεστώς τόσο στο προσωπικό επίπεδο όσο και στο περιουσιακό και μάλιστα στις κληρονομικές σχέσεις. Ανώτατα διοικητικό τους όργανο είναι η γενική συνέλευση των μελών, η Αδελφότητα, η οποία εκλέγει και τα πρόσωπα που συγκροτούν το μοναστηριακό συμβούλιο, τη Γεροντία, καθώς και τον Ηγούμενο/Ηγουμένη. Η οργάνωσή τους και ο τρόπος διοίκησή τους βασίζεται στις γενικές αρχές των νομικών προσώπων του Αστικού Κώδικα
description: The present thesis deals with the monastic type of isichastiria. The isichastiria are cenobite(common life) monasteries obeying the civil law and its members are devoted to God. They are founded as institutions according to the regulations of common law, articles 108-121 of the civil code. This is a legal form that appeared in recent years and its governed by the laws of the state, that regulate the matters of monasticism and the canonic law of the Orhtodox Church. This means that there is no any privileged status for their administration. The members of the isichastiria who obtain the monastic quality are in a special legal status, both on personal and on financial matters and especially on hereditary relations. The highest administrative body of this legal institution is the general assebly of its members(brotherhood), which elects the persons that constitute the monastic council(gerondia) as well as the "father"(igoumenos), "mother" (igoumeni). Their structure and their administration is based on the general principles of the civil code

description: We study the kinetics of nonlinear irreversible fragmentation. Here fragmentation is induced by interactions/collisions between pairs of particles, and modelled by general classes of interaction kernels, and for several types of breakage models. We construct initial value and scaling solutions of the fragmentation equations, and apply the "non-vanishing mass flux "criterion for the occurrence of shattering transitions. These properties enable us to determine the phase diagram for the occurrence of shattering states and of scaling states in the phase space of model parameters.

description: Ο οικοτουρισμός προτείνεται ως ένα εγχείρημα συμφιλίωσης του περιβαλλοντισμού και του τουρισμού. Ωστόσο, έχει διατυπωθεί ευρέως η άποψη ότι η τουριστική διάσταση του οικοτουρισμού υπερισχύει της περιβαλλοντικής. Η παρούσα έρευνα εξέτασε το ζήτημα της κατανομής των δύο διαστάσεων του οικοτουρισμού από την πλευρά των επισκεπτών προστατευόμενων περιοχών με την μέθοδο της Κριτικής Ανάλυσης Λόγου, που στοχεύει να ανακαλύψει της αναπαραστάσεις της πραγματικότητας που οικοδομούνται μέσω της επικοινωνίας. Συγκεκριμένα, αναλύθηκε ο τρόπος αναπαράστασης της οικοτουριστικής δραστηριότητας στα βιβλία επισκεπτών της προστατευόμενης περιοχής του δάσους Δαδιάς και σε ταξιδιωτικά άρθρα του περιοδικού "Γεωτρόπιου". Τα αποτελέσματα έδειξαν ότι και στα δύο κειμενικά είδη οικοδομήθηκε μια δυϊστική αντί για δυαδική απεικόνιση του οικοτουρισμού. Ετσι, η παρούσα έρευνα έδειξε ότι το ζήτημα της μη ισόρροπης ανάπτυξης των δύο διαστάσεων του οικοτουρισμού δεν εκφράζεται ως επικράτηση, αλλά ως απομόνωση της μιας όψης από την άλλη
description: Ecotourism is proposed on a conciliation of environmentalism with tourism. However, it has been largely claimed that the tourism dimension usually overrides the environmentalist one. The present study examined the distribution of the two components of ecotourism in terms of visitors of protected areas with the method of Critical Discourse Analysis, which aims at revealing the representations of reality built through communication. Specifically, it analysed the way visitors of the Dadia forest reserve represented ecotourism activity in visitors' book, as well as how travel articles of the "Geotropio" magazine transformed Greek protected areas into public ecotourism destination images to be conoumed by virtual visitors. The results showed that both genres constructed a dualist instead of a dual depiction of ecotourism. Consequently, the present study suggests that the non-balanced development of the two dimensions of ecotourism is not expresed as a dominance but rather as an isolation of the one component from the other
Girl talk : feminist rights discourse and the struggle for equality
Creators: name: Dearing, Christine M.
Publisher: name: University of British Columbia
Year: 2008

description: The customs of Western society face increasing pressure as the "postmodern" notion that knowledge and reason are constructs of a discourse that suppresses some aspects of experience and highlights others, gains legitimacy. Feminists have seized this notion of discourse to challenge the way society has marginalized women's existence. Canadian feminists, in particular, have developed a counterdiscourse of rights to challenge the dominant discourse and its formal approach to equality. By lobbying the federal government to entrench a more substantive notion of equality in the Canadian Charter of Rights and Freedoms; by seeking to protect the spirit of the equality guarantees during the discussions on the Meech Lake Accord; and by acting as intervenors before the Supreme Court of Canada in Andrews v. The Law Society of British Columbia, feminists broadened the conception of equality to include the notion of disadvantage. Many feminists question the use of rights discourse to challenge inequality because of the tendency of traditional legal discourse to rely on precedents that are intrinsically androcentric and to frame issues in rational terms that overlook the relative experiences of women. However, rights discourse can challenge the dominant system by exposing unquestioned norms and symbols; redefining women's identity; and developing a body of law sensitive to women's equality issues. In Canada, rights discourse enjoys additional authority because of the practical and symbolic force of the Charter's constitutional guarantees of equality. Canadian feminist rights discourse illustrates the potential of rights language to shift the dominant meaning of equality by introducing a feminist voice into discussions previously carried out by men. Nonetheless, Canadian feminist rights discourse faces a number of challenges. The postmodern scepticism about theory in general also undermines the theoretical basis upon which feminism is built and allows other counterdiscourses to compete with feminist rights discourse to challenge dominant meanings. As well, feminists must acquire legitimacy for their discourse in the face of institutional structures that give men greater power. The issue of representation must also be addressed to allow feminist rights discourse to speak for the range of women in society. Feminists must work to gain recognition for the idea that society is gendered and that women have suffered oppression as a result. And they must continue to challenge traditional understandings of equality to move us closer to the day when the dominant discourse conceives of equality in substantive terms that incorporate the notions of disadvantage and oppression.

description: Αντικείμενο της μελέτης είναι ο ρόλος των ανθρωπόμορφων αναπαραστάσεων στη συγκρότηση υποκειμενικών θέσεων κατά τη Νεολιθική εποχή στις περιοχές της Κεντρικής Μακεδονίας και της Θεσσαλίας. Το θεωρητικό πλαίσιο που αναπτύσσεται αντιμετωπίζει τον υλικό πολιτισμό ως λόγο που συγκροτεί υποκείμενα και στόχος είναι να εξεταστούν οι διαρθρώσεις αυτού του λόγου, δηλ. ο τρόπος που αποδίδεται η ανθρώπινη μορφή στον υλικό πολιτισμό και συγκεκριμένα στην κατηγορία των ειδωλίων. Τελικός στόχος είναι ανασύνθεση των πρακτικών που αναδιάρθρωναν τις δομές και τις υποκειμενικές θέσεις από τις οποίες οι άνθρωποι δρούσαν στο εκάστοτε κοινωνικό πεδίο. Τα βασικά συμπεράσματα της μελέτης είναι ότι α)κατά τις πρώϊμες φάσεις της Νεολιθικής υπάρχει μια έμφαση στην εικόνα της κίνησης μέσω της απόδοσης ποικίλων στάσεων και χειρονομιών και β)αντίθετα στις ύστερες φάσεις της Νεολιθικής η εικόνα των μορφών είναι στατική. Στην ύστερη αυτή φάση τα μακεδονικά στοιχεία δίνουν μια έμφαση και στις εγχαράξεις, ενώ αντίθετα τα θεσσαλικά επικεντρώνεται στην απόδοση του κεφαλιού. Ενα άλλο συμπέρασμα της μελέτης είναι ο έντονα τοπικός χαρακτήρας αρκετών χαρακτηριστικών που μελετήθηκαν, όπως η απόδοση των γεννητικών οργάνων ή της κόμης των μορφών
description: The subject of this study is the role of anthropomorphic imagery in the constitution of subjectivities in Central Macedonia and Thessaly during the Neolithic period. To accomplish this, the author draws upon a theoretical framework, according to which material culture is seen as discourse. Consequently the author investigates the articulations of this discourse, that is, the way in which the human figure is rendered in the material culture and particularly in the category of figurines. The aim of this investigation is to reconstruct the practices thatt rearticulated structures and subjective positions in the social field. The main results of the study are that a)there is an emphasis on the image of movement, through the depiction of postures and gestures during the earliel Neolithic and b)on the contrary, there is an absence of these traits pointing to a static image during the later Neolithic. In this later phase there is also an emphasis on incisions in Macedonia and an emphasis on the head in Thessaly. Afinal resultof the study is the local character of many of the traits studied
On analogy between transition to turbulence in fluids and plasticity in solids
Creators: name: Ananiev, Sergey
Publisher: name: arXiv
Year: 2006
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The subject of this work is the instability mechanism of simple shear flows, like Hagen-Poiseuille pipe flow, which is a long-standing problem in fluid mechanics [1,2]. A possible analogy with phenomenological theory of ideal plasticity in solids is explored. It allows an extension of the Navier-Stokes equations making the simple shear flows unstable. Following von Mises [4], the existence of maximal allowed shear stress or "yield stress" in fluid is assumed. After the actual stresses have reached this value, a new physical mechanism will be activated attempting to reduce them. This mechanism results in a pressure-like force, which has to be added to the Navier-Stokes equations. The yield stress itself is a material constant, which does not depend on the Reynolds number of particular flow. It will be shown how to estimate its value from experimental data. To demonstrate how the character of flow changes if the additional force is taken into account, an unsteady flow in a 2D nozzle is presented. The momentum source was introduced in the Navier-Stokes equations through the user-defined function's interface offered by Fluent [6]. The initial data and the results of simulation are summarized in appendix.

The "Marinha do Tejo" is composed of the vessels, owners and arrais that, each year, are registered in the book of the "Marinha do Tejo", which is kept at the Museum of the Navy.

The Tagus Navy is the name by which the vessels and the community of seafarers and craftsmen that navigated and lived along its banks became known. It has a historical and cultural significance that translates aspects that reflect well our national identity and what is most genuine in our riverside populations, made up of the community of seafarers and craftsmen who navigated and lived along its banks. Men of work who, through their actions, defined the geography of a country and shaped a nation.

The Tagus Navy has been perpetuated to the present day through generous and dedicated work that transmits to younger generations sovereignty over the knowledge that is the fruit of centuries of living experience. Today it has a fleet of approximately eighty vessels, which constitute a living pole of the Museum of the Navy.

The fundamental pillars for the communication are: the Vessels; the People, their knowledge and traditions; and the Region and the Municipalities (Arco do Tejo).

description: Consideration of the adiabatic character of radiation expansion in early Universe leads to the conclusion that equilibrium distribution of the primordial radiation in the presence of charged particles could be different from the Planck distribution in some regions of the spectrum. The equilibrium distribution of electromagnetic radiation (the black body radiation) is generalized for the system containing an extremely dense fully ionized plasma. The conditions of the adiabatic expansion of radiation for the model of the early Universe are found.

Infants' ability to use language as a guide to inductive inference
Creators: name: Desjardins, Renée Nicole
Publisher: name: University of British Columbia
Year: 2008

description: The present studies were designed to address whether infants use language to guide their inferences about novel objects. In Study 1, forty-eight infants from two age groups (16-18 and 20-22 months) participated in a task which used exploratory play as a window on inferential abilities. Infants explored novel toys presented in pairs: The first toy produced an interesting but non-obvious property while the second toy was invisibly altered such that it failed to produce the target property. In the Labeled condition both toys were moderately similar in appearance and given a common label. In the Unlabeled Control condition moderately similar toys were talked about in a general way as were dissimilar toys in the Baseline Control condition. The frequency of infants' attempts to elicit the target property was marginally higher in the Unlabeled Control condition compared to the Baseline Control condition. This suggests that infants may have, with difficulty, perceived the greater degree of similarity between moderately similar toys in the Unlabeled Control condition compared to the dissimilar toys in the Baseline Control condition. When toys were labeled, infants across the 16-22 month range attempted to reproduce the target property with the second toy more frequently than in the Unlabeled Control condition indicating that they used the object labels to guide their inferences about object properties. Study 2 compared the frequency of infants' attempts to elicit the target property from the second toy when two toys were given a common label (Same Label condition) as opposed to different labels (Different Label condition). Eighteen 20- to 22-month-olds showed a marginally higher frequency of target actions in the Same Label condition compared to the Different Label condition suggesting that they understood that two toys should share a common label before that label can be used to guide expectations about object properties. Together these studies provide evidence that infants from 20 months of age understand that object labels can be used as a guide to inference, and some suggestion that this ability may be present from 16 months.

description: Following the idea, recently, proposed by the present authors for the two-level pairing model, the Lipkin model is reexamined. It is a natural generalization of the method already developed by the present authors with Kuriyama. This model is a schematic model for many-fermion system and obeys the su(2)-algebra. It is shown that the use of the Schwinger boson representation, the model is expressed in terms of the su(1,1) times su(1,1)-algebra and with the aid of the MYT mapping method, it is disguised from the orginal form in terms of the Holstein-Primakoff representation. Further, under various coherent states, the classical counterparts are derived. It is concluded that the Lipkin model can be treated in the common ring as that of the two-level pairing model.

description: We present an updated cosmic-ray mass composition analysis in the energy range $10^{16.8}$ to $10^{18.3}$ eV from 334 air showers measured with the LOFAR radio telescope, and selected for minimal bias. In this energy range, the origin of cosmic rays is expected to shift from galactic to extragalactic sources. The analysis is based on an improved method to infer the depth of maximum $X_{\rm max}$ of extensive air showers from radio measurements and air shower simulations. We show results of the average and standard deviation of $X_{\rm max}$ versus primary energy, and analyze the $X_{\rm max}$-dataset at distribution level to estimate the cosmic ray mass composition. Our approach uses an unbinned maximum likelihood analysis, making use of existing parametrizations of $X_{\rm max}$-distributions per element. The analysis has been repeated for three main models of hadronic interactions. Results are consistent with a significant light-mass fraction, at best fit $23$ to $39$ $\%$ protons plus helium, depending on the choice of hadronic interaction model. The fraction of intermediate-mass nuclei dominates. This confirms earlier results from LOFAR, with systematic uncertainties on $X_{\rm max}$ now lowered to 7 to $9$ $\mathrm{g/cm^2}$. We find agreement in mass composition compared to results from Pierre Auger Observatory, within statistical and systematic uncertainties. However, in line with earlier LOFAR results, we find a slightly lower average $X_{\rm max}$. The values are in tension with those found at Pierre Auger Observatory, but agree with results from other cosmic ray observatories based in the Northern hemisphere.

description: Purpose: The aim of this study was to develop the Language Exposure Assessment Tool (LEAT) and to examine its cross-linguistic validity, reliability, and utility. The LEAT is a computerized interview-style assessment that requests parents to estimate language exposure. The LEAT yields an automatic calculation of relative language exposure and captures qualitative aspects of early language experience. Method: Relative language exposure as reported on the LEAT and vocabulary size at 17 months of age were measured in a group of bilingual language learners with varying levels of exposure to French and English or Spanish and English. Results: The LEAT demonstrates high internal consistency and criterion validity. In addition, the LEAT’s calculation of relative language exposure explains variability in vocabulary size above a single overall parent estimate. Conclusions: The LEAT is a valid and efficient tool for characterizing early language experience across cultural settings and levels of language exposure. The LEAT could be a useful tool in clinical contexts to aid in determining whether assessment and intervention should be conducted in one or more languages.

description: We present results for the electronic and magnetic structure of Mn and Fe clusters on Nb(110) surface, focusing on building blocks of atomic chains as possible realizations of topological superconductivity. The magnetic ground states of the atomic dimers and most of the monatomic chains are determined by the nearest-neighbor isotropic interaction. The dependence on the crystallographic direction as well as on the atomic coordination number is analyzed via an orbital decomposition of this isotropic interaction based on the spin-cluster expansion and the difference in the local density of states between ferromagnetic and antiferromagnetic configurations. A spin-spiral ground state is obtained for Fe chains along the [$1\overline{1}0$] direction as a consequence of the frustration of the isotropic interactions. Here, a flat spin-spiral dispersion relation is identified, which can stabilize spin spirals with various wave vectors together with the magnetic anisotropy. This may lead to the observation of spin spirals of different wave vectors and chiralities in longer chains instead of a unique ground state.

description: Το μυστήριο της Θείας Οικονομίας ξεκινά από την ίδια τη δημιουργία, η οποία είναι έργο του Τριαδικού Θεού. Η δημιουργία εκ του μη όντος καθορίζει τη μετέπειτα πορεία της κτιστής πραγματικότητας. Η πτώση δεν κατέχει κεντρική θέση στο μυστήριο της Θείας Οικονομίας. Αποτελεί ένα συμβάν που δεν αλλοιώσει το σχέδιο του Θεού για την σωτηρία του ανθρώπου. Κέντρο της Θείας Οικονομίας αποτελεί η ενσάρκωση η οποία χαρακτηρίζεται ως δεύτερη δημιουργία. Ο Χριστός είναι ο ένας και ο αυτός Θεός Λόγος που δημιουργεί και αναδημιουργεί. Μέσα σ'αυτό το σχήμα η Θεία Οικονομία παρουσιάζει μια αρραγή. Βασική σταθμοί της ένσαρκης οικονομίας αποτελούν η βάπτιση, ο σταυρός και η ανάσταση του Χριστού. Η σωτηρία όμως τελικά κατανοείται με τους όρους της ανακεφαλαίωσης
description: The mystery of the divine economy start with the creation. The creation is the work of the holy Trinity. The creation of the nothing define the meaning of the creatures. The fall has not a central meaning of the creatures. The fall has not a central place in the mystery of the divine economy; is only an accident that cannot change the plan of God for the Salvation. The incarnation is the center of the divine economy and incarnation is the center of the divine economy and characterized like second creation. The Christ is the same verbe of God who create and recreate. In this plan the divine economy obtain a unity. The baptem, the crucifixion, the resurrection are the basic points of the myster of the incarnation. The Salvation, finally, is understand with the terms of the recapitulation

description: The development of new techniques to quantitatively measure gene expression in cells has shed light on a number of systems that display oscillations in protein concentration. Here we review the different mechanisms which can produce oscillations in gene expression or protein concentration, using a framework of simple mathematical models. We focus on three eukaryotic genetic regulatory networks which show "ultradian" oscillations, with time period of the order of hours, and involve, respectively, proteins important for development (Hes1), apoptosis (p53) and immune response (NFkB). We argue that underlying all three is a common design consisting of a negative feedback loop with time delay which is responsible for the oscillatory behaviour.

description: Γίνεται μια αντικειμενική ανάλυση δεδομένων σε πλεγματικά σημεία στα πεδία γεωδυναμικού ύψους και θερμοκρασίας αέρα για την ανίχνευση κλειστών χαμηλών της στάθμης 500hRa αλλά και σε άλλες κύριες στάθμες(1000, 850, 700, 300 και 200hPa). Η διαδικασία οδηγεί στην εξακρίβωση τριών κέντρων δραστηριότητας στη λεκάνη της κεντρικής και ανατολικής Μεσογείου. Αυτά είναι στην Τουρκία στη Μαύρη Θάλασσα και στη Γένοβα. Μόνο τα μισά χαμηλά συνοδεύονται από θερμοκρασιακά ελάχιστα τα οποία επεκτείνονται σε κάθε στάθμη εκτός της στάθμης 200hPa όπου κυριαρχούν θερμοκρασιακά μέγιστα. Η κυκλογένεση ευνοείται στην Τουρκία, Αδριατική και Γένοβα ενώ η κυκλοδιάλυση στην Τουρκία και Αδριατική. Η κυκλογένεση ευνοείται από τον παράγοντα της αστάθειας και καταστέλλεται από την ευστάθεια σε μεγάλο βαθμό κατά τη θερμή περίοδο του έτους. Οι ισχυρές βροχοπτώσεις στην Ελλάδα συνδέονται περισσότερο με την εμφάνιση κέντρων θετικής μεταφοράς στροβιλισμού που σχετίζονται με τα χαμηλά παρά εμ την ίδια την παρουσία των κλειστών χαμηλών. Το ίδιο ισχύει σε μεγαλύτερο βαθμό για την εμφάνιση χαλαζιού στην ίδια περιοχή
description: An objective analysis of gridded data in the fields of geopotential heigh and temperature is performed at the 500hPa level and other mandatory levels. The analysis showed the presence of three activity centers in the field of occurence frequency. These centers are : the center of Turkey, the center of Black Sea and the center in the gulf of Genoa. Only 50% of 500 hPa lows are related except 200hPa where temperature maxima prevail above 500hPa lows. Cyclogenesis is favored in three areas of central and east Mediterranean region. These are namely the Turkey, the Adriatic and the Genoa cyclogenesis areas Cyclolysis on other hand is favored over Turkey and Adriatic Sea. Cyclogenesis in this part of the year is mostly favored by vertical instability. Intence rainfalls over Greece in the warm part of the year is mainly related to possitive vorticity advection centers and not to the presence of lows itself. The same relation occurres concerning the observation of hail over the Imathia-Pella valey

description: One of the challenges faced by many video providers is the heterogeneity of network specifications, user requirements, and content compression performance. The universal solution of a fixed bitrate ladder is inadequate in ensuring a high quality of user experience without re-buffering or introducing annoying compression artifacts. However, a content-tailored solution, based on extensively encoding across all resolutions and over a wide quality range is highly expensive in terms of computational, financial, and energy costs. Inspired by this, we propose an approach that exploits machine learning to predict a content-optimized bitrate ladder. The method extracts spatio-temporal features from the uncompressed content, trains machine-learning models to predict the Pareto front parameters, and, based on that, builds the ladder within a defined bitrate range. The method has the benefit of significantly reducing the number of encodes required per sequence. The presented results, based on 100 HEVC-encoded sequences, demonstrate a reduction in the number of encodes required when compared to an exhaustive search and an interpolation-based method, by 89.06% and 61.46%, respectively, at the cost of an average Bjøntegaard Delta Rate difference of 1.78% compared to the exhaustive approach. Finally, a hybrid method is introduced that selects either the proposed or the interpolation-based method depending on the sequence features. This results in an overall 83.83% reduction of required encodings at the cost of an average Bjøntegaard Delta Rate difference of 1.26%.

description: This PHD dissertation deals with the issue of information dispersal in wired and wireless environments of the World Wide Web. It aims at reducing the access latency and at the same time improving the performance of the underline communication networks. In particular, the thesis focuses on the technique of caching ; develops novel replacement policies for the caches and it develops new prefectching algorithms which act complementary to caching. Also, it presents a novel, low-complexity, high-performance broadcast scheduling algorithm, which can be used to create a dynamic air-cache for the clients of a wireless network
Concepts of mental health and mental illness : a comparison of definitions and checklists in the Abhidharmakośabhāṣya and the diagnostic and statistical manual of mental disorders (DSM-III-R)

description: This study examines concepts of mental health and mental illness in Vasubandhu's Abhidharmakośabhāṣya (AKBh), and the American Psychiatric Association's Diagnostic And Statistical Manual Of Mental Disorders (third edition, revised) (DSM-III-R). The choice of these texts was made based on their importance and influence. Two general problems are encountered in this study. There are great philosophical differences between the texts. These differences are most problematic in regards to terminology. Buddhist terminology is used wherever appropriate and possible. Unfortunately, sometimes North American terminology and categories infiltrate this. The translation of the AKBh poses a second problem. Due to time constraints, the english translation was used, however this translation is faulty in a number of places. Corrected translations are offered in square brackets. This study is conducted on two levels. One is content-oriented, exploring the relevant concepts in each text and examining the cultural, historical, religious, and theoretical influences that form or underlie these concepts. The second level is exploratory and more like hypothesis testing. Both texts use the format of lists, and a primary aim of this study is to identify and compare, not details, but broad structural similarities and differences between such lists. In such a way, the phenomenon and use of lists in such texts may be better understood. Through this approach one finds that concepts of mental health and mental illness in each text are influenced by values and norms. In particular, DSM-III-R reflects largely secular values, while the AKBh contains a soteriological psychology. These differences are linked to basic concepts of the norm -- against which mental health and mental illness are measured -- as average or ideal. Due to such differences in values and norms, a comparison of individual items on the lists is not possible. However, as these same values and norms form or underlie the lists, a comparison of such broad influences or structures is methodologically justifiable. The finding that DSM-III-R shows the influence of values and norms, indicates that it may be impossible to formulate any concept of mental health or mental illness without such influences.

description: Several disastrous security attacks can be attributed to delays in patching software vulnerabilities. While researchers and practitioners have paid significant attention to automate vulnerabilities identification and patch development activities of software security patch management, there has been relatively little effort dedicated to gain an in-depth understanding of the socio-technical aspects, e.g., coordination of interdependent activities of the patching process and patching decisions, that may cause delays in applying security patches. We report on a Grounded Theory study of the role of coordination in security patch management. The reported theory consists of four inter-related dimensions, i.e., causes, breakdowns, constraints, and mechanisms. The theory explains the causes that define the need for coordination among interdependent software and hardware components and multiple stakeholders' decisions, the constraints that can negatively impact coordination, the breakdowns in coordination, and the potential corrective measures. This study provides potentially useful insights for researchers and practitioners who can carefully consider the needs of and devise suitable solutions for supporting the coordination of interdependencies involved in security patch management.

Η παρούσα έρευνα έγινε πειραματικά σε υδραυλικό κανάλι και δόθηκαν συσχετίσεις μεταξύ της χρονικής διάρκειας αερισμού και του όγκου του εισερχόμενου αέρα ως πολλαπλάσιο μέγεθος του αρχικού όγκου του αεριζόμενου χώρου. Σημειώνεται ότι στη σχετική βιβλιογραφία γίνεται αναφορά μόνο στον αριθμό ανανεώσεων του αέρα ενός χώρου στη μονάδα του χρόνου. Στις σχετικές μελέτες δεν λαμβάνεται υπ'όψη ως παράμετρος η απώλεια θερμικής ενέργειας για τη θέρμανση ή ψύξη των χώρων, που σήμερα αποκτά ιδιαίτερη σημασία λόγω της πολιτικής που ακολουθείται για εξοικονόμηση των καυσίμων και ιδιαίτερα του πετρελαίου.
