Mises en traduction théâtrale: Valère Novarina — Dimitris Dimitriadis, contextualisations multiples d’un événement scénique
No full textTheatre in translation: Valère Novarina — Dimitris Dimitriadis , multiple contextualisations of a stage eventIn terms of theatre, translation involves not only linguistic transfers on the level of discourse signification, but also a transfer of functions in relation to other signs of theatre action. Theatre translation as a component of a whole dramatic process has to consider among other criteria the author’s playwright basic position which leads the speech action to the stage. In this context, the V. Novarina and D. Dimitriadis’ approaches present opposite points of view, with different cultural references, corresponding to a contemporary theatrical discourse which could contribute to an important extent, to the translator’s work.Theatre in translation: Valère Novarina — Dimitris Dimitriadis , multiple contextualisations of a stage eventIn terms of theatre, translation involves not only linguistic transfers on the level of discourse signification, but also a transfer of functions in relation to other signs of theatre action.

Study of ad hoc networks
No full textThe object of this dissertation is the study of ad hoc networks. As ad hoc are characterised the wireless networks that are not supported by preexisting infrastructure. This study focuses on two layers of the ISO/OSI networking stack and namely the data link and the network layer. The behaviour of the medium access protocol EY-NPMA was studied via both analytical and numerical means. Aiming at improving the efficiency, two protocols based on EY-NPMA have been designed (EY-NPMA/TP and EY-NPMA/ZP), which allow the dynamic upgrading of the priority levels of a subset of the network population. Also, a mechanism for estimating the offered load was designed and evaluated, allowing the network to use the optimal working parameters of the EY-NPMA protocol (Adaptive EY-NPMA). Adaptive EY-NPMA with variable yield further improves the protocol efficiency by allowing the interaction between the elimination and the yield phases. Finally, the performance of the EDCF medium access protocol was evaluated using numerical methods, while it was also compared with EY-NPMA and EY-NPMA/ZP. In the network layer, the research focused on the problem of routing. Using numerical methods, the value of distributed gateways was quantified in a clustered ad hoc network, while a medium access protocol which enables their usage was designed and evaluated. Also, the SNLSR routing protocol was proposed, which uses sequence numbers in order to reduce the transmission of redundant topology information in the network.Αντικείμενο αυτής της διδακτορικής διατριβής αποτελεί η μελέτη των αδόμητων δικτύων. Ως αδόμητα ορίζονται τα ασύρματα δίκτυα που δεν υποστηρίζονται από προϋπάρχουσα υποδομή. Η μελέτη εστιάζεται σε δύο επίπεδα του μοντέλου ISO/OSI, του επιπέδου ζεύξης και του επιπέδου δικτύου. Στα πλαίσια της διατριβής μελετήθηκε η συμπεριφορά του πρωτοκόλλου πολλαπλής πρόσβασης EY-NPMA, τόσο μέσω αναλυτικών όσο και μέσω αριθμητικών μεθόδων. Με στόχο την βελτίωση της αποδοτικότητας, σχεδιάστηκαν δύο πρωτόκολλα που βασίζονται στο EY-NPMA (EY-NPMA/TP και EY-NPMA/ZP) τα οποία επιτρέπουν την δυναμική αναβάθμιση της προτε- ραιότητας μέρους του δικτυακού πληθυσμού. Επίσης, μελετήθηκε μηχανισμός εκτίμησης του προσφερόμενου φορτίου, ώστε να επιλέγει το EY-NPMA τις βέλτιστες παραμέτρους λειτουργίας σε κάθε περίσταση (προσαρμοστικό EY-NPMA). Το προσαρμοστικό EY-NPMA με μεταβλητή αποκομιδή βελτιώνει περαιτέρω την αποδοτικότητα του πρωτοκόλλου, επιτρέποντας την αλληλε- πίδραση μεταξύ των φάσεων απαλοιφής και αποκομιδής. Τέλος, μέσω προσομοιώσεων αξιολο- γήθηκε η απόδοση του πρωτοκόλλου πολλαπλής πρόσβασης EDCF, ενώ συγκρίθηκε επίσης με τα EY-NPMA και EY-NPMA/ZP. Στο επίπεδο δικτύου, η έρευνα εστίασε στο πρόβλημα της δρομο- λόγησης. Χρησιμοποιώντας αριθμητικές μεθόδους ποσοτικοποιήθηκε η σημασία των κατανεμη- μένων πυλών σε ένα κυψελοποιημένο δίκτυο, ενώ προτάθηκε πρωτόκολλο πολλαπλής πρόσβασης που επιτρέπει την ενεργοποίησή τους. Επίσης, προτάθηκε και αξιολογήθηκε το πρωτόκολλο δρομολόγησης για αδόμητα δίκτυα SNLSR, το οποίο χρησιμοποιεί τους αριθμούς ακολουθίας για την μείωση της πλεονάζουσας πληροφορίας τοπολογίας που εκπέμπεται στο δίκτυο

No full textThe Psychoanalytic Concept of Jouissance and the Kindling Hypothesis
No full textThis article aims to define the conceptual field of jouissance in Lacanian theory, and put forth the hypothesis of a relationship between certain neurophysiological mechanisms and specific clinical phenomena where jouissance is “kindled” and outside the control of the symbolic process. First, the author briefly introduces Lacan's notion of jouissance and the way it draws on Freud's theorization, and describes the preliminary stages of this conceptual field in Lacan's work. Then, the jouissance related to two other concepts: repetition, with its Freudian and Lacanian nuances, as well as the—exclusively—Lacanian concept of the object petit a. Lacan's later conceptualization of language as jouissance (the notion of lalangue) is then discussed in relation to Freud's early ideas (“Letter 52”) on the different kinds of inscriptions that help form the mental apparatus. Finally, the author tries to formulate a hypothesis regarding specific neurophysiological mechanisms, based on clinical situations where jouissance becomes “kindled” and escapes the control of the symbolic processes through the neurophysiological mechanisms of conditioning, “kindling-sensitization” and “excitotoxicity.” In these cases, jouissance can have a destructive effect on the body and can affect, among others organs, the brain—a process the author has previously described heuristically as the “psychosomatic diseases of the brain.” This would be a special mechanism of automatism that would be triggered under the specific conditions of the fragility of the signifying chain (foreclosure of the Name-of-the-Father or solidification of the signifying chain) in combination with biological factors, including genetic factors. In this process, signifiers are reduced to signals, which in turn may be reduced to stimuli, with a tendency toward self-perpetuation, while affects are reduced to emotions and moods. Thus, conditioning and kindling-sensitization could also be understood in terms of a “semiotic reduction.” Can we therefore consider that certain phenomena of automatism and certain deficits (delusional moods, schizophrenic apathy, etc.) could be seen as psychosomatic disorders of the brain? The phenomena in question might also serve—albeit at random—as a kind of shield to mitigate excessive jouissance
Traffic Safety of Disabled Pedestrians at Signalized Crosswalks
No full textMobility of disabled people has as a basic guarantee the traffic safety. Walking for disabled may have improved considerably compared to the past, but there are stillissues such as the safe crossing at signalized crosswalks. Also, the availability of studies on safe crossing for disabled pedestrians is limited. While it has been understood how pedestrians perceive safety at crosswalks, no similar study has been done for disabled pedestrians. The main purpose of this study is to fill the gap and make it more understandable how disabled pedestrians perceive traffic safety at signalized crosswalks. The literature showed significant factors that influence the pedestrian crossing behavior, such as the gender, the kind of disability, the presence of traffic lights at crosswalks, and weather conditions. Most ofthese factors are significantly related to the perception of safety.The main methodology included the interviews, and the survey, using the statistical analysis with the hypothesis tests and the Generalized Linear Model for the process of the data. The results proved that factors such as gender, age, kind of disability, the walking frequency had a significant impact on the perceived safety of disabled pedestrians. Yet, the study brought up important solutions that can improve safety perception, such as technological solutions like artificial intelligence traffic lights and infrastructure solutions such as the construction of underground crosswalks and refuges islands at long distance crosswalks. A recommendation is that the authorities and transport planners should emphasize to the solutions proposed to improve safety. A further scientific recommendation would the study of the objective safety in the future, comparing it with the perceived safety. This study has contributed significantly to the understanding of the issues faced by disabled pedestrians at crosswalks and it can be a starting point for further improvements in the mobility of disabled pedestrians and their lives in the future.Transport, Infrastructure and Logistic
Study and modelling of the prefractionation and distillation of work-arising-gases-derived synthetic crude oil
No full textThe purpose of this study was to create a theoretical model for the distillation of synthetic crude oil (syncrude) into straight-run naphtha, kerosene and gas oil fractions, at a scale of 235 ktfeed/year. To that end, a process model was created that receives the output of a Co-LTFT process as raw feed. The raw feed was prefractionated to remove the majority of the unreacted syngas, inert gases, light hydrocarbons (C1-C4) and water. The remaining stream was syncrude, primarily composed of alkanes and 1-alkenes in the C5-50 range.A Base Case was designed in ASPEN plus, with a distillation unit with two steam strippers and three pumparounds. The goal was to receive the syncrude and separate naphtha, kerosene and gas oil cuts, with least 90% purity and recovery of the components. The Fenske-Underwood-Gilliland method was used to estimate the number of stages and reflux ratio of the column, and the Kirkbride method was used to find an initial estimate for the feed stage. The TBP curves of the cuts were compared with similar cuts from literature and found to be similar. The Base Case underwent a sensitivity analysis in order to ascertain the effect of different design and process parameters on the separation quality and utility consumption. The parameters that were tested are cold condensate temperature, feed stage, condenser duty, feed temperature and stripping steam flow rate to the ADU. According to the sensitivity analysis results, for optimal separation between the syncrude and the other gases in the raw feed, the gases must be purged at a temperature of -70°C. Furthermore, the optimal configuration for the distillation of the given syncrude into naphtha, kerosene and gas oil fractions with at least 90% purity and recovery is as follows: The ADU has 40 equilibrium stages and a condenser duty of approximately -5.7 MW. The feed must be heated to 310°C and enter the column at stage 37. The stripping steam flow rate must be around 1.3 kg/s. Five alternative processes were modelled as well, with similar inputs to the column model, and the results of the distillate separation quality and utility consumption were documented as well. The alterations of the alternative cases include replacing the stripping steam with a reboiler in one of the strippers, adding a stripper from where an additional product was drawn, concentrating the pumparound duty on the condenser, using a vacuum distillation unit to fractionate the residue of the atmospheric distillation unit, and employing a heat integration network.The most important conclusions are listed. Firstly, the side strippers must use low pressure stripping steam instead of reboilers. Next, the minimum number of products must be drawn off in order to minimize utility consumption at a given separation quality. Furthermore, heat integration can save up to 50% in total utility consumption (heat and cooling water). It is recommended that further research, including a cost estimation, is conducted on refineries that produce on-specification final products.<br/
The other students with special educational needs and the attainment gap
No full textThe gap in pupils’ attainment has been a central educational issue in England in recent years. Schools try to address the problem by developing strategies to provide support specifically for low-achieving pupils, mainly from disadvantaged or cultural or ethnic-minority backgrounds. The author argues that this conceptualization of the attainment issue is problematic. It encourages schools to exclude pupils who are more advanced from their attention. As a result, they do not receive specialized support that could help them actualize their full potential. If we seek inclusive education, the question should shift from closing the attainment gap for a narrow range of pupils to raising achievement for everyone. This includes pupils who already perform well and could excel if they had additional support, even if this makes the attainment gap bigger. The author links this problem with how we conceptualize and define ability, special need, underachievement, equity, and “gap” in education
Constituting the Field
No full text This article critically explores Harry Torrance’s four-volume edited collection Qualitative Research Methods in Education. The author argues that this text is an important intervention in the constitution of a meta-discourse on qualitative research today. Torrance pays particular attention to the field of education, providing much needed historical and genealogical perspectives on contemporary discussions in the field. </jats:p
