Drawing in the margins : identity and subjectivity in contemporary autobiographical comics

Mon projet de thèse démontre comment le genre de la bande dessinée peut être mobilisé de façon à déstabiliser les idéologies identitaires dominantes dans un contexte autobiographique. À partir de théories contemporaines de récits de vie et de leurs emphase sur la construction du sujet au travers du processus autobiographique, j’explore les façons par lesquelles les propriétés formelles de la bande dessinée permettent aux artistes féminines et minoritaires d’affirmer leurs subjectivités et de s’opposer aux idéaux hégémoniques reliés à la représentation du genre, du traumatisme, de la sexualité, de l’ethnicité, et du handicap, en s’auto-incarnant à même la page de bande dessinée. Par une analyse visuelle formelle, ma thèse prouve que les esthétiques hyper-personnelles du dessin à la main découlant d’une forme ancrée dans l’instabilité générique et le (re)mixage continu des codes verbaux et visuels permettent aux artistes de déstabiliser les régimes de représentation conventionnels dans une danse complexe d’appropriation et de resignification qui demeure toujours ouverte à la création de nouveaux sens. Suite à l’introduction, mon second chapitre explique la résistance de Julie Doucet par rapport aux plaisirs visuels découlant de la contemplation des femmes dans la bande dessinée par son utilisation du concept originairement misogyne de la matérialité féminine grotesque comme principe génératif à partir duquel elle articule une critique de la forme et du contenu des représentations normatives et restrictives du corps féminin. Le troisième chapitre considère la capacité de la bande dessinée à représenter le traumatisme, et se penche sur les efforts de Phoebe Gloeckner visant à faire face aux abus sexuels de son enfance par l’entremise d’un retour récursif sur des souvenirs visuels fondamentaux. Le chapitre suivant maintient que la nature sérielle de la bande dessinée, sa multimodalité et son association à la culture zine, fournissent à Ariel Schrag les outils nécessaires pour expérimenter sur les codes visuels et verbaux de façon à décrire et à affirmer le sens identitaire en flux de l’adolescent queer dans sa quadrilogie expérimentale Künstlerroman. Le cinquième chapitre suggère que l’artiste de provenance Libanaise Toufic El Rassi utilise la forme visuelle pour dénoncer les mécanismes générateurs de préjugés anti-Arabes, et qu’il affirme son identité grâce au pouvoir de rhétorique temporaire que lui procure l’incarnation d’un stéréotype connu. Mon dernier chapitre démontre comment Al Davison emploie la bande dessinée pour mettre en scène des rencontres d’observations dynamiques avec le spectateur implicite pouvant potentiellement aider l’auteur à éviter le regard objectivant généralement associé à la perception du handicap.

The autotelic experience : a design approach to user experience

Si les principes d’utilisabilité guident la conception de solutions de design interactif pour s’assurer que celles-ci soient « utilisables », quels principes guident la conception d’objets interactifs pour s’assurer que l’expérience subjective de l’usager (UX) soit adéquate et mémorable? Que manque-t-il au cadre de l‘UX pour expliquer, comprendre, et anticiper en tant que designer une expérience mémorable (‘an experience’; Dewey, 1934)? La question centrale est issue d’une double problématique : (1) le cadre théorique de l’UX est incomplet, et (2) les processus et capacités des designers ne sont pas considérés et utilisés à leur pleine capacité en conception UX. Pour répondre à cette question, nous proposons de compléter les modèles de l’UX avec la notion d’expérience autotélique qui appartient principalement à deux cadres théoriques ayant bien cerné l’expérience subjective, soit l’expérience optimale (ou Flow) de Csikszentmihalyi (1988) et l’expérience esthétique selon Schaeffer (2001). L’autotélie est une dimension interne du Flow alors qu’elle couvre toute l’expérience esthétique. L’autotélie est une expérience d’éveil au moment même de l’interaction. Cette prise de conscience est accompagnée d’une imperceptible tension de vouloir faire durer ce moment pour faire durer le plaisir qu’il génère. Trois études exploratoires ont été faites, s’appuyant sur une analyse faite à partir d’un cadre théorique en trois parties : le Flow, les signes d’activité non verbale (les gestes physiques) et verbale (le discours) ont été évalués pour voir comment ceux-ci s’associent. Nos résultats tendent à prouver que les processus spatiaux jouent un rôle de premier plan dans l’expérience autotélique et par conséquent dans une UX optimale. De plus, ils suggèrent que les expériences pragmatique et autotélique sont ancrées dans un seul et même contenu, et que leur différence tient au type d’attention que le participant porte sur l’interaction, l’attention ordinaire ou de type autotélique. Ces résultats nous ont menés à proposer un modèle pour la conception UX. L’élément nouveau, resté jusqu’alors inaperçu, consiste à s’assurer que l’interface (au sens large) appelle une attitude réceptive à l’inattendu, pour qu’une information puisse déclencher les processus spatiaux, offrant une opportunité de passer de l’attention ordinaire à l’attention autotélique. Le nouveau modèle ouvre la porte à une meilleure valorisation des habiletés et processus du designer au sein de l’équipe multidisciplinaire en conception UX.

Artiste ou espion ? Dessiner le paysage dans l’Italie du XVIe siècle

Stories of artists who were arrested and accused of spying while drawing landscape remain relatively unknown in the history of open-air drawing in the Renaissance period, when landscape raised new aesthetic issues as well as strategic and military tensions. This article focuses on Francisco de Holanda, a Portuguese artist who travelled through Italy between 1538 and 1542. Having embarked on a visual-spying mission of the peninsula's fortresses, he wrote essays on drawing and painting in which landscape representation took on a strategic dimension ans was celebrated as such. At the same time, treatises on the 'art of travelling' provided a great deal of advice on how to draw and map foreign territories 'without raising suspicion', while treatises on fortification often addressed military secret. Examining the figure of the draughtsman together with his graphic production at the service of art or war leads to a wider reflection on the development of a certain vision of landscape in the modern West.

An Error-Localization, Validation and Optimization Tool for Embedded Code Augmentation: an Architecture Oriented Approach

Embedded systems are usually designed for a single or a specified set of tasks. This specificity means the system design as well as its hardware/software development can be highly optimized. Embedded software must meet the requirements such as high reliability operation on resource-constrained platforms, real time constraints and rapid development. This necessitates the adoption of static machine codes analysis tools running on a host machine for the validation and optimization of embedded system codes, which can help meet all of these goals. This could significantly augment the software quality and is still a challenging field.Embedded systems are usually designed for a single or a specified set of tasks.

The focus of this work is to develop methods that automatically localize faults as well as optimize the code and thus improve the debugging process as well as quality of the code.Validation is done with the help of rules of inferences formulated for the target processor. The rules govern the occurrence of illegitimate/out of place instructions and code sequences for executing the computational and integrated peripheral functions. The stipulated rules are encoded in propositional logic formulae and their compliance is tested individually in all possible execution paths of the application programs. An incorrect sequence of machine code pattern is identified using slicing techniques on the control flow graph generated from the machine code.An algorithm to assist the compiler to eliminate the redundant bank switching codes and decide on optimum data allocation to banked memory resulting in minimum number of bank switching codes in embedded system software is proposed. A relation matrix and a state transition diagram formed for the active memory bank state transition corresponding to each bank selection instruction is used for the detection of redundant codes. Instances of code redundancy based on the stipulated rules for the target processor are identified.This validation and optimization tool can be integrated to the system development environment. It is a novel approach independent of compiler/assembler, applicable to a wide range of processors once appropriate rules are formulated. Program states are identified mainly with machine code pattern, which drastically reduces the state space creation contributing to an improved state-of-the-art model checking. Though the technique described is general, the implementation is architecture oriented, and hence the feasibility study is conducted on PIC16F87X microcontrollers. The proposed tool will be very useful in steering novices towards correct use of difficult microcontroller features in developing embedded systems.

A Faster 2D Technique for the design of Combinational Digital Circuits Using Genetic Algorithm

Combinational digital circuits can be evolved automatically using Genetic Algorithms (GA). Until recently this technique used linear chromosomes and and one dimensional crossover and mutation operators. In this paper, a new method for representing combinational digital circuits as 2 Dimensional (2D) chromosomes and suitable 2D crossover and mutation techniques has been proposed. By using this method, the convergence speed of GA can be increased significantly compared to the conventional methods. Moreover, the 2D representation and crossover operation provides the designer with better visualization of the evolved circuits. In addition to this, a technique to display automatically the evolved circuits has been developed with the help of MATLAB

Soft Computing Approach for Optimization of siRNA Efficiency Prediction for Post-transcriptional Gene Silencing

Post-transcriptional gene silencing by RNA interference is mediated by small interfering RNA called siRNA. This gene silencing mechanism can be exploited therapeutically to a wide variety of disease-associated targets, especially in AIDS, neurodegenerative diseases, cholesterol and cancer on mice with the hope of extending these approaches to treat humans. Over the recent past, a significant amount of work has been undertaken to understand the gene silencing mediated by exogenous siRNA. The design of efficient exogenous siRNA sequences is challenging because of many issues related to siRNA. While designing efficient siRNA, target mRNAs must be selected such that their corresponding siRNAs are likely to be efficient against that target and unlikely to accidentally silence other transcripts due to sequence similarity. So before doing gene silencing by siRNAs, it is essential to analyze their off-target effects in addition to their inhibition efficiency against a particular target. Hence designing exogenous siRNA with good knock-down efficiency and target specificity is an area of concern to be addressed. Some methods have been developed already by considering both inhibition efficiency and off-target possibility of siRNA against agene. Out of these methods, only a few have achieved good inhibition efficiency, specificity and sensitivity. The main focus of this thesis is to develop computational methods to optimize the efficiency of siRNA in terms of “inhibition capacity and off-target possibility” against target mRNAs with improved efficacy, which may be useful in the area of gene silencing and drug design for tumor development. This study aims to investigate the currently available siRNA prediction approaches and to devise a better computational approach to tackle the problem of siRNA efficacy by inhibition capacity and off-target possibility. The strength and limitations of the available approaches are investigated and taken into consideration for making improved solution. Thus the approaches proposed in this study extend some of the good scoring previous state of the art techniques by incorporating machine learning and statistical approaches and thermodynamic features like whole stacking energy to improve the prediction accuracy, inhibition efficiency, sensitivity and specificity. Here, we propose one Support Vector Machine (SVM) model, and two Artificial Neural Network (ANN) models for siRNA efficiency prediction. In SVM model, the classification property is used to classify whether the siRNA is efficient or inefficient in silencing a target gene. The first ANNmodel, named siRNA Designer, is used for optimizing the inhibition efficiency of siRNA against target genes. The second ANN model, named Optimized siRNA Designer, OpsiD, produces efficient siRNAs with high inhibition efficiency to degrade target genes with improved sensitivity-specificity, and identifies the off-target knockdown possibility of siRNA against non-target genes. The models are trained and tested against a large data set of siRNA sequences. The validations are conducted using Pearson Correlation Coefficient, Mathews Correlation Coefficient, Receiver Operating Characteristic analysis, Accuracy of prediction, Sensitivity and Specificity. It is found that the approach, OpsiD, is capable of predicting the inhibition capacity of siRNA against a target mRNA with improved results over the state of the art techniques. Also we are able to understand the influence of whole stacking energy on efficiency of siRNA. The model is further improved by including the ability to identify the “off-target possibility” of predicted siRNA on non-target genes. Thus the proposed model, OpsiD, can predict optimized siRNA by considering both “inhibition efficiency on target genes and off-target possibility on non-target genes”, with improved inhibition efficiency, specificity and sensitivity. Since we have taken efforts to optimize the siRNA efficacy in terms of “inhibition efficiency and offtarget possibility”, we hope that the risk of “off-target effect” while doing gene silencing in various bioinformatics fields can be overcome to a great extent. These findings may provide new insights into cancer diagnosis, prognosis and therapy by gene silencing. The approach may be found useful for designing exogenous siRNA for therapeutic applications and gene silencing techniques in different areas of bioinformatics.

Formal Multilevel Hierarchical Verification of Synchronous MOS Circuits

I have designed and implemented a system for the multilevel verification of synchronous MOS VLSI circuits. The system, called Silica Pithecus, accepts the schematic of an MOS circuit and a specification of the circuit's intended digital behavior. Silica Pithecus determines if the circuit meets its specification. If the circuit fails to meet its specification Silica Pithecus returns to the designer the reason for the failure. Unlike earlier verifiers which modelled primitives (e.g., transistors) as unidirectional digital devices, Silica Pithecus models primitives more realistically. Transistors are modelled as bidirectional devices of varying resistances, and nodes are modelled as capacitors. Silica Pithecus operates hierarchically, interactively, and incrementally. Major contributions of this research include a formal understanding of the relationship between different behavioral descriptions (e.g., signal, boolean, and arithmetic descriptions) of the same device, and a formalization of the relationship between the structure, behavior, and context of device. Given these formal structures my methods find sufficient conditions on the inputs of circuits which guarantee the correct operation of the circuit in the desired descriptive domain. These methods are algorithmic and complete. They also handle complex phenomena such as races and charge sharing. Informal notions such as races and hazards are shown to be derivable from the correctness conditions used by my methods.

A Theory of Quantitative Inference Applied to a Mechanical Design Compiler

This thesis presents the ideas underlying a computer program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers from predefined catalogs for the optimal selection of components implementing the design. Unlike programs for designing single components or systems, the program provides the designer with a high level "language" in which to compose new designs. It then performs some of the detailed design process. The process of "compilation" is based on a formalization of quantitative inferences about hierarchically organized sets of artifacts and operating conditions. This allows the design compilation without the exhaustive enumeration of alternatives.

Electrical Design: A Problem for Artificial Intelligence Research

This report outlines the problem of intelligent failure recovery in a problem-solver for electrical design. We want our problem solver to learn as much as it can from its mistakes. Thus we cast the engineering design process on terms of Problem Solving by Debugging Almost-Right Plans, a paradigm for automatic problem solving based on the belief that creation and removal of "bugs" is an unavoidable part of the process of solving a complex problem. The process of localization and removal of bugs called for by the PSBDARP theory requires an approach to engineering analysis in which every result has a justification which describes the exact set of assumptions it depends upon. We have developed a program based on Analysis by Propagation of Constraints which can explain the basis of its deductions. In addition to being useful to a PSBDARP designer, these justifications are used in Dependency-Directed Backtracking to limit the combinatorial search in the analysis routines. Although the research we will describe is explicitly about electrical circuits, we believe that similar principles and methods are employed by other kinds of engineers, including computer programmers.

Implantación de un SIG basado en software libre para el estudio de recursos hídricos y procesos hidrológicos

En este trabajo se describe la solución ideada para la implantación de un Sistema de Información Geográfica que debe dar servicio al Instituto Universitario del Agua y del Medio Ambiente de la Universidad de Murcia y al Instituto Euromediterráneo del Agua. Dada la naturaleza de ambas instituciones, se trata de una herramienta orientada fundamentalmente al estudio de recursos hídricos y procesos hidrológicos. El proceso se inició con una identificación de las necesidades de los usuarios (con perfiles y requerimiento diferentes) y el posterior desarrollo del diseño conceptual que pudiera asegurar la satisfacción de estas necesidades. Debido a que los requerimientos de los usuarios así lo demandaban, se ha tenido en cuenta tanto a usuarios que trabajan en entorno linux como a otros que lo hacen en entorno windows. Se ha optado por un sistema basado en software libre utilizando GRASS para el manejo de información raster y modelización; postgis (sobre postgreSQL) y GRASS para la gestión de información vectorial; y QGIS, gvSIG y Kosmo como interfaces gráficas de usuario. Otros programas utilizados para propósitos específicos han sido R, Mapserver o GMT

Diseño de Plan Exportador para Corpoempack Ltda.

Debido a la globalización acelerada que esta experimentando el mundo, la economía y los mercados mundiales están creciendo cada día más y más, esto hace que pequeñas empresas tenga que crecer a la velocidad que el mundo lo pide, este es el caso de Corpoempack Ltda., una PyME diseñadora y productora de artículos de expresión social como tarjetas de felicitación, amor, apoyo, papel regalo, cuadernos, agendas, carpetas entre otros, que en vista de que el mercado nacional se estaba quedando pequeño frente a tantos oferentes vieron la necesidad de ampliar sus horizontes intentando conquistar mercados externos comenzando a exportar a Ecuador y otros países vecinos, pero no siendo esto suficiente se propusieron penetrar otros continentes por eso la razón de esta investigación tomando 2 posibles países: México como puerta de entrada a Norteamérica, y España como la posibilidad de ingreso a Europa. Se realizo un estudio detallado de los 2 posibles países viendo las ventajas y desventajas para exportar allá y a su vez abrir una tienda de expresión social con productos exclusivos Corpoempack. Como resultado se obtuvo que la mejor opción seria exportar a España por facilidades en acuerdos comerciales, el tamaño de las colonias latinas y la fuerza que tienen en el mercado y por ultimo la competencia que existe en este campo como almacenes exclusivos de expresión social es baja, así que seria una gran oportunidad de darle a los españoles productos innovadores y netamente colombianos. Proyectando el negocio a 5 años, considerando que las condiciones del mercado se mantienen o mejoran, será un negocio muy rentable y con miras a un rápido crecimiento, claro esta teniendo en cuenta las mejoras tanto organizacional como en estructura en la casa matriz Colombia ya que hay varios puntos débiles que reforzar en clima y administración.
