Matière en acte : les rapports entre conception et matérialité dans la production matérielle numérique / Matter in actuality : the relationship between design and materiality within digital material productionLallemand, Ianis 05 December 2017 (has links)
Alors que l'évolution des pratiques de fabrication numérique dans les champs de l'art, de l'architecture et du design semble pointer vers l'émergence d'une « nouvelle matérialité », marquée par les développements contemporains de la robotique, de la computation et des sciences des matériaux, les discours entourant l'usage des machines à commande numérique restent trop souvent dominés par une compréhension passive de l'idée de matière. Cette thèse se propose d'actualiser la vision des rapports entre conception numérique et matérialité, en développant des schémas productifs ouverts à l'expression de formes d'agentivité matérielle. Cherchant à dépasser l'articulation prescriptive traditionnelle entre conception et fabrication, elle défend l'idée d'une redistribution de l'autorité vers un réseau d'acteurs productifs autonomes. L'argument développé vise avant tout à mettre à jour des méthodologies pratiques ainsi qu'un cadre conceptuel partageables, susceptibles d'être réinvestis par d'autres praticiens. Cinq expérimentations pratiques, reliées par leurs usages prospectifs de la programmation et de la fabrication numérique, en constituent l'ossature empirique. Mobilisant des auteurs comme Gilbert Simondon et Andrew Pickering, le travail de conceptualisation réalisé permet d'opérer un retour réflexif sur ces expériences, et d'en situer les enjeux au regard d'un certain nombre de précédents historiques, tels ceux de la production numérique non standard et de la cybernétique. / Recent developments in digital fabrication practices across the fields of art, architecture and design have inspired the notion of a “new materiality” — a rethinking of our relationship to the physical world in light of the ever-increasing convergence between robotics, computation and materials science. Yet, the very use of computer-controlled machinery remains, more often than not, envisioned in terms of a passive understanding of matter. This thesis aims at offering an updated vision of the relationship between materiality and design, by developing new production schemes allowing for an expression of material agency. Criticizing the traditional idea of a prescriptive, deterministic link between design and fabrication, the proposed argument reframes authority as a shared resource, spread through a network of productive and autonomous agents. The thesis' main outcomes consist in a set of practical methodologies as well as an encompassing conceptual framework, which may both be reinvested by other practitioners. Informed by and grounded in practice, the research builds on five experiments, adopting a prospective approach towards programming and digital fabrication. Drawing on authors like Gilbert Simondon and Andrew Pickering, the accompanying conceptualization allows for a reflexive discussion of the thesis' practical developments, while situating them in respect to such historical precedents as non standard production and cybernetics.

[en] CODE-SWITCHING: MULTIDISCIPLINARY APPROACHES / [pt] CODE-SWITCHING: PERSPECTIVAS MULTIDISCIPLINARESRENATA SOBRINO PORTO 13 December 2006 (has links)
[pt] Esta dissertação investiga o fenômeno lingüístico
conhecido na literatura em línguas
em contato como code-switching, que consiste no uso
alternado de dois ou mais códigos
por falantes bilíngües ou multilíngües em uma mesma
interação conversacional. O
estudo desta prática discursiva em diversas línguas tem
obtido interesse crescente nas
últimas três décadas. Duas abordagens principais
prevalecem: sócio-pragmática e
sintático-gramatical. Enquanto a primeira se volta aos
aspectos sócio-pragmáticos de
produção individual, através da categorização,
quantificação e análise das funções
pragmáticas e motivações sócio-psicológicas subjacentes ao
code-switching, a segunda
busca formular restrições formais e padrões de ocorrência
universais para este
comportamento lingüístico. Este trabalho tem como objetivo
apresentar uma
sistematização e avaliação bibliográfica da literatura
internacional em code-switching
através da apresentação e caracterização das principais
linhas de pesquisa, ressaltando
as obras de referência e os caminhos apontados por cada
abordagem. A necessidade da
apresentação estruturada dos diversos aspectos do code-
switching encontradas na
literatura sobre línguas em contato se deve ao fato de que
a pesquisa sobre este
fenômeno é incipiente no Brasil e o acesso ao material é
ainda restrito. Esta pesquisa,
portanto, busca preencher este espaço e tornar a
literatura em code-switching acessível à
academia brasileira. / [en] This dissertation investigates the linguistic phenomenon
referred to as codeswitching
in languages in contact´s literature. Code-switching
consists of the alternate
use of two or more codes by bilinguals or multilinguals in
the same verbal interaction.
The study of this discursive practice in several languages
has obtained increasing
interest in the last three decades. Two main approaches
prevail: socio-pragmatic and
grammatical-syntactic. Whilst the first approach focuses
on the socio-discursive aspects
of individual production through the categorization,
quantification and analysis of codeswitching
pragmatic functions and socio-psychological motivations;
the second one
intends to formulate formal constraints and patterns of
occurrence of this linguistic
behavior. The present work aims at presenting a
bibliographic systematization and
evaluation of the international literature in code-
switching through the presentation and
characterization of its major research lines, emphasizing
the reference works and the
directions provided by each approach. The need for the
structured presentation of the
several aspects of code-switching found in the literature
in languages in contact is due to
the fact that research on this phenomenon is incipient in
Brazil and the access to this
material is still restricted. This research, therefore,
seeks to fill this gap and make the
literature in code-switching accessible to the Brazilian
academy.

Etické kodexy v soudobém českém mediálním systému / Ethical Codes in the present Czech media systemHoráčková, Anna January 2018 (has links)
Master's Thesis focuses on current position of ethics in the Czech media. The main subject is the code of ethics (or code of conduct). The first part of the thesis offers a theoretical background of the topic. I am pursuing the terminology referred to the media ethics topic. Together with scholarly resources I provide definitions of terms such as ethics, morality and code of ethics in media. Summary of relevant Czech codes of conduct is essential for this thesis. First, I present the codes in a brief list and table, more detailed analysis follows. The focus is on differences and specification of each of them. After that I present an analysis of ethical rules valid in foreign countries - European states and the United States in particular. Theoretical part is followed by practical part of the thesis. It is based on interviews with experts which are semi- anonymous and semi-structured. I interview eight employees of Czech media after formulating several hypotheses. I chose experts who have been working in media for many years - mainly chief editors or top managers in press, TV, radio or online media. One of the most important chapters is the confirmation or refutation of the stated hypotheses. Based on the conclusion of the interviews, I create a universal code of ethics that might be applicable on...

Nový zákoník práce - jeho klady a zápory / New Labour Code {--} its positives and negativesTENKLOVÁ, Ivana January 2008 (has links)
The task of this thesis named {\clqq}New Labour Code {--} its positives and negatives`` is to compare the old Labour Code with the new one, to show the changes and updates and their impact to practice, to find the positives and negatives in its application. After long negotiations, the Labour Code began to be valid in January 2007 in a new form, but only by the {\clqq}technical novel`` and by the finding of the Constitutional court the main inadequacies were eliminated. The question remains if the Labour Code as an independent Code is necessary. It is usual in some countries that the labour-law tasks are treated in the Civil Code, but our legal regulations result from the Soviet concept of the legal system. Currently the framework of the new Civil Code is finished; one of the authors is Professor Karel Eliáš, who is just the protagonist of incorporation the labour law into the Civil Code. On the other hand, the labour law nowadays is so wide and specific, that its incorporation back into the civil law would have been extremely difficult.

Previous issue date: 2012-02-16 / Since the very first graphical user interfaces, progress indicators have been widely used to provide
feedback regarding the execution of a system long-running tasks. In fact, practical experience
and formal experiments suggest that such indicators are an important user interface
tool, as they enhance the attractiveness and effectiveness of the programs that incorporate them.
However, in order to make progress feedback possible, the system services involved must provide
on-line monitoring capabilities. As the software systems become increasingly larger and
more complex — often involving complex interactions between various different components
and abstraction layers —, the crosscutting nature of monitoring concerns can introduce several
inherent challenges to the software development: (1) code quality degradation with respect
to tangling and scattering; (2) costly software evolution and maintenance difficulties; (3) absence
of specific development patterns and regular standardized process guidance; (4) loss of
development productivity; and (5) inconsistent monitoring results.
In this context, this work provides an analysis of monitoring requirements, possible approaches
towards its implementation along with an analysis of the main benefits and weaknesses
involved. Furthermore, it is proposed and evaluated a solution to aid the software development
by overcoming the monitoring-related inherent challenges, rather by mitigating or completely
eliminating the problems. The solution consists of a framework, extended libraries, and generic
software process guidelines regarding the monitoring requirements, with focus on the Rational
Unified Process (RUP), for exemplification purpose, but not limited to it.

Pin-up ! Figures et usages de la pin-up cinématographique au temps du « pré-Code » (1930- 1934) / Pin-up ! A study of cinematographic pin-up figures during Pre-Code (1930-1934)Boissonneau, Mélanie 02 April 2013 (has links)
Cette thèse se propose de confronter un objet singulier, les pin-up, à un espace-temps tout aussi particulier : la période dite du pré-Code hollywoodien. Il s’agit tout d’abord de définir la pin-up comme figure féminine et cinématographique, et de proposer d’aller au-delà de la femme-objet qu’elle est censée incarner. L’étude attentive (par le biais notamment d’analyses de séquences) d’archétypes de pin-up produits entre 1930 et 1934 dans une perspective culturaliste influencée par les études de genre, permet, d’une part de déconstruire l’idée d’un pré-Code synonyme de liberté cinématographique. D’autre part, un retour sur l’histoire des pin-up et leur usage féministe potentiel, autorise cette figure féminine hyper-sexualisée à devenir un outil d’analyse des relations de genre, apte à révéler les mécanismes, parfois subtilement dissimulés, de la domination masculine. Les stratégies opposées par les personnages de pin-up au cadre patriarcal, sont à cet égard révélatrices. Les carrières cinématographiques de Betty Boop, de Jean Harlow, et de Mae West, étudiées sous cette lumière, indiquent quelles formes ces stratégies peuvent prendre. Les pin-up évoluant dans le genre de l’horreur et le personnage de Jane Parker incarné par Maureen 0’Sullivan durant les six premiers Tarzan de la MGM complètent ce passage en revue. La diversité des archétypes choisis fait in fine apparaître une difficulté commune aux pin-up cinématographiques, quel que soit leur statut ontologique : celle d’exister. / The goal of the present dissertation is to confront a specific object, the “pin-up”, to aspecific time and location: the so called « Pre code » Hollywood era. First of all, we wish todefine the pin-up as both a feminine and cinematographic figure, and to go beyond themere “woman as object “ that she is frequently reduced to. A careful study (relying, amongother, on sequence analysis) of pin-up archetypes created between 1930 and 1934 in acultural perspective, influenced by gender studies, makes it possible, first, to deconstructthe notion that Pre-code era has been a period of cinematographic freedom. Moreover,looking back at the history and evolution of the pin-up, and understanding how they can beused in a feminist agenda, helps turning this hypersexualised feminine figure into a deviceto analyze gender relationships, able to reveal the mechanisms, sometimes cleverlyconcealed, of masculine domination. In this respect, the strategies that pin-up charactersresort to in order to fight patriarchal order are revealing. Pin-up evolving in the horrorgenre, or the character of Jane Parker impersonated by Maureen O’Sullivan in MGM’s sixfirst Tarzan should complete this survey. The variety of archetypes that have been selectedhere seem, eventually, to lay bare a common difficulty, shared by all cinematographic pinup,regardless of their ontological status - their mere existence.

Fiabilisation de la technologie courant porteur en ligne en vue de piloter des actionneurs d’aéronefs / Reliability of the power line technology in rder to drive aircraft actuatorsLarhzaoui, Thomas 02 July 2014 (has links)
Dans le cadre de l’avion plus électrique, les avionneurs cherchent à remplacer les commandes de vol hydrauliques par des commandes de vol électriques, avec pour intérêt de diminuer le poids, et d’améliorer la flexibilité des équipements aéronautiques. Sachant que sur un A380, la distance cumulée pour les câbles peut atteindre plus de 500 km, la solution consistant à faire cohabiter les transmissions de données et de puissances au sein de mêmes câbles grâce à la technologie CPL pourrait contribuer à réduire la masse de câble dans un avion. Cependant les câbles de puissance n’ont pas été dimensionnés pour transmettre un signal informationnel, et les équipements présents sur le réseau sont source de bruits. Dans ce contexte nous souhaitons montrer la faisabilité d’une transmission CPL soumise aux contraintes avioniques tout en respectant les normes aéronautiques. La première partie des travaux a consisté à mesurer le canal de propagation sur un banc de test représentatif d’un environnement aéronautique. Le canal de propagation est composé de deux coupleurs de type inductif ou capacitif dont le but est de connecter les câbles de télécommunication au réseau de puissance et d’une paire bifilaire torsadée de puissance d’une longueur de 32 m représentative d’un réseau HVDC ±270 V. Nous avons alors testé trois architectures différentes : l’architecture point-À-Point avec coupleur capacitif, l’architecture point-À-Point avec coupleur inductif et l’architecture point-À-Multipoints avec coupleur inductif. Le but de ces mesures a été d’évaluer la fonction de transfert du canal sur la bande [1 ; 100] MHz. Nous avons alors calculé les éléments caractéristiques du canal comme la bande de cohérence et l’étalement des retards. Après la caractérisation du canal de propagation, nous avons choisi et dimensionné les algorithmes de traitement du signal au regard des spécifications aéronautiques à savoir : un débit utile de 10 Mbit/s, un temps de latence de 167-334 μs, un TEB de 10-12 et le respect du gabarit de la DO-160 en émission conduite. Au regard de la fonction de transfert du canal, nous avons choisi d’utiliser l’OFDM comme technique de transmission. Ainsi, à l’aide de la caractérisation du canal de propagation nous avons au cours d’une étude paramétrique défini les paramètres de la transmission OFDM au regard des spécifications de débit et de temps réel. Dans un second temps, nous avons implanté les paramètres OFDM ainsi que la modélisation du canal de propagation dans une chaine de transmission Matlab. Cette chaine nous a alors permis de vérifier les paramètres issues de l’étude paramétrique ainsi que de définir le système de codage de canal (Reed-Solomon et code convolutif) pour respecter les spécifications aéronautiques. La dernière partie de cette thèse a consisté en l’étude du système de synchronisation. Du fait de la stabilité du canal de propagation, nous avons considéré une synchronisation fine du système lors d’une phase d’initialisation puis nous nous somme focalisé sur le dimensionnement d’un système de suivi dans le but de corriger le décalage de fenêtre FFT dû au défaut de fréquence d’échantillonnage. Pour limiter les pertes de débit lors de la phase de suivi, nous avons proposé une estimation de l’erreur de fréquence d’échantillonnage sur la phase des données reçues sur une période de 20 symboles OFDM. / In the new aircrafts, hydraulic flight control systems are replaced by electric flight control systems. The main interests are a better flexibility of the aeronautical equipments and a decrease in maintenance costs and construction costs, but the major problem is the increasing of the wires length. In order to decrease this length, it has been proposed to use power line communications (PLC) technology for flight control systems. The decrease of wire will first decrease aircraft weight and therefore the consumption of kerosene and on the other hand will simplify maintenance and construction. The first part of this work is the measurement and the characterisation of the propagation channel on an aeronautic test bench (with HVDC supply and loads). This channel is composed of two couplers (inductive or capacitive) in order to connect the telecommunication system on the power wires with galvanic isolation and one twisted pair of 32 m longs. We have tested three architectures: the point-To-Point architecture with capacitive coupler, the point-To-Point architecture with inductive coupler and the point-To-Multipoint architecture with inductive coupler. The purpose of these measurements is to measured the transfer function on the [1 ; 100] MHz bandwidth. Then, we have computed the channel parameters like the coherence bandwidth and the delay spread. The second step was the design of the signal processing algorithm in order to satisfy the aeronautical specifications: a useful bite rate of 10 Mbit/s, a latency of 167- 334 μs, a BER of 10-12 and the respect of the DO-160 gauge in conducted emissions. For the transmissions, we have chosen the OFDM technology which has been use with success in other PLC systems. With the channel characterization, we have proposed a parametric study in order to define the OFDM parameters to satisfy the bite rate and the real time constraints. After, we compute digital simulations with Matlab to check the OFDM parameters. With these simulations, we have also defined the channel coding parameters (Reed-Solomon and convolutional coding) to satisfy the aeronautical specifications. The last part of this study was the design of the synchronisation system. Because of the channel stability, we considered a precise synchronisation after an initialisation period. Then, we focus on the estimation of the FFT shift, due to the sampling frequency shift, during a following-Up period. In order to avoid the decrease of the latency and the bitrate due to the pilot symbols or pilot sub-Carriers insertion, we proposed to correct the FFT shift with the receive data thanks to the maximal likelihood algorithm.

Systematic Literature Review and Controlled Pilot Experimental Evaluation of Test Driven Development (TDD) vs. Test-Last Development (TLD) / Systematic Literature Review and Controlled Pilot Experimental Evaluation of Test Driven Development (TDD) vs. Test-Last Development (TLD)Munir, Hussan, Moayyed, Misagh January 2012 (has links)
Context: Test-Driven development (TDD) is a software development approach where test cases are written before actual development of the code in iterative cycles. TDD has gained attention of many software practitioners during the last decade since it has suggested several benefits in the software development process. However, empirical evidence of its dominance in terms of internal code quality, external code quality and productivity is fairly limited. Objectives: The aim behind conducting this study is to explore what has been achieved so far in the field of Test-driven development. The study reports the benefits and limitation of TDD compared to TLD and the outcome variables in all the reported studies along with their measurement criteria. Additionally, an experiment is conducted to see the impact of Test-driven development (TDD) on internal code quality, external code quality and productivity compared to Test-Last development (TLD). Methods: In this study two research methodologies are used specifically systematic literature review according to Kitchenham guidelines and controlled pilot experiment. In systematic literature review number of article sources are considered and used, including Inspec, Compendex, ACM, IEEE Xplore, Science direct (Elsevier) and ISI web of science. A review protocol is created first to ensure the objectivity and repeatability of the whole process. Second, a controlled experiment is conducted with professional software developers to explore the assumed benefits of Test-Driven development (TDD) compared to Test-Last development (TLD). Results: 9 distinct categories related to Test-driven development (TDD) are found that are investigated and reported in the literature. All the reported experiments revealing very little or no difference in internal code quality, external code quality and productivity in Test-Driven development (TDD) over Test-Last development (TLD). However, results were found contradictory when research methods are taken into account because case studies tend to find more positive results in the favor Test-Driven development (TDD) compared to experiments possibly due to the fact that experiment are mostly conducted in artificially created software development environment and mostly with students as a test subjects. On the other hand, experimental results and statistical analysis show no statistically significant result in the favor TDD compared to TLD. All the values found related to number of acceptance test cases passed (Mann-Whitney U test Exact Sig. 0.185), McCabe’s Cyclomatic complexity (Mann-Whitney U test Exact Sig. 0.063), Branch coverage (Mann-Whitney U test Exact Sig. 0.212), Productivity in terms of number of lines of code per person hours (Independent sample Ttest Sig. 0.686), productivity in terms number of user stories implemented per person hours (Independent sample T-test Sig. 0.835) in experiment are statistically insignificant. However, static code analysis (Independent sample T-test Sig. 0.03) result was found statistically significant but due to the low statistical power of test it was not possible to reject the null hypothesis. The results of the survey revealed that the majority of developers in the experiment prefer TLD over TDD, given the lesser required level of learning curve as well as the minimum effort needed to understand and employ TLD compared to TDD Conclusion: Systematic literature review confirms that the reported benefits of TDD development compared to Test-Last development are very small. However, case studies tend to find more positive results in the favor of Test-Driven development (TDD) compared to Test-Last development (TLD). Similarly, experimental findings are also confirming the fact that TDD has small benefits over TLD. However, given the small effect size there is an indication that (Test-Driven development) TDD endorses less complex code compared to Test-Last development (TLD). / Systematic literature review confirms that the reported benefits of TDD development compared to Test-Last development are very small.

Code Profiling : Static Code AnalysisBorchert, Thomas January 2008 (has links)
Capturing the quality of software and detecting sections for further scrutiny within are of high interest for industry as well as for education. Project managers request quality reports in order to evaluate the current status and to initiate appropriate improvement actions and teachers feel the need of detecting students which need extra attention and help in certain programming aspects. By means of software measurement software characteristics can be quantified and the produced measures analyzed to gain an understanding about the underlying software quality. In this study, the technique of code profiling (being the activity of creating a summary of distinctive characteristics of software code) was inspected, formulized and conducted by means of a sample group of 19 industry and 37 student programs. When software projects are analyzed by means of software measurements, a considerable amount of data is produced. The task is to organize the data and draw meaningful information from the measures produced, quickly and without high expenses. The results of this study indicated that code profiling can be a useful technique for quick program comparisons and continuous quality observations with several application scenarios in both industry and education.

Local and non-local processing in the retina / Traitement local et non-local dans la rétineDeny, Stéphane 12 December 2016 (has links)
L’information visuelle est transmise de la rétine au cerveau par les cellules ganglionnaires. Il existe plusieurs types de cellules ganglionnaires, chaque type formant une mosaïque qui couvre l’intégralité de la scène visuelle. Comprendre la manière dont ces neurones encodent collectivement la scène visuelle est essentiel pour au moins deux raisons: - La manière dont une population de neurones encodent collectivement une information sensorielle reste jusqu’à aujourd’hui mystérieuse. La rétine est un système idéal pour étudier cette question: elle a en effet une structure en couches 2D qui se prête idéalement à l’enregistrement d’une population complète de neurones à grande échelle, et elle opère une transformation complexe de la scène visuelle. - Certaines maladies qui mènent à la cécité ne connaissent aujourd’hui pas de traitement. Plusieurs stratégies de restauration visuelle basées sur la stimulation directe de cellules ganglionnaires sont le sujet de recherches actives. Il pourrait être nécessaire de reproduire en imitant le code neural produit par la rétine pour optimiser les résultats de ces stratégies thérapeutiques. Au cours de ma thèse, j’ai travaillé sur deux questions complémentaires, qui sont liées à ces deux sujets respectivement. / Visual information is conveyed from the retina to the brain through ganglion cells. Ganglion cells are divided in different cell types, and each of them form a mosaic sampling the entire visual scene. Understanding how these neurons encode the visual scene is essential for at least two reasons: -It is still unclear how a population of neurons collectively code sensory information. The retina is an ideal system to study this issue: while it performs complex processing on the visual stimulus, its 2-D structure makes it suitable for large-scale recordings of complete populations of neurons. -Some diseases leading to blindness have currently no cure. Several visual restoration strategies based on the direct stimulation of ganglion cells are currently being investigated. Emulating the retinal code may be necessary to optimize the results of these therapeutic approaches. In my thesis I have worked on two complementary questions, that are related to these two topics.
