Ce travail de thèse a été initié par Renault, en collaboration avec le Centre de Recherche en Automatique de Nancy (CRAN), dans le but de poser les bases d'une méthodologie générique permettant d'évaluer l'état de santé de moyens de production. Cette méthodologie est issue d’une réflexion conjointe machine - produit en lien avec les exigences industrielles. La méthodologie proposée est basée sur une approche PHM (Prognostics and Health Management) et est structurée en cinq étapes séquentielles. Les deux premières étapes sont développées dans ce travail de thèse et en constituent les contributions scientifiques majeures. La première originalité représente la formalisation des connaissance issues de la relation machine-produit. Cette connaissance est basée sur l'extension de méthodes existantes telle que l’AMDEC et l’HAZOP. La formalisation des concepts de connaissance et de leurs interactions est matérialisée au moyen d'une méta-modélisation basée sur une modélisation UML (Unified Modelling Language). Cette contribution conduit à l'identification de paramètres pertinents à surveiller, depuis le niveau du composant jusqu'au niveau de la machine. Ces paramètres servent ensuite d’entrée au processus d'élaboration du bilan de santé machine, qui représente la deuxième originalité de la thèse. L'élaboration de ces indicateurs de santé est basée sur des méthodes d’agrégation, telle que l'intégrale de Choquet, soulevant la problématique de l'identification des capacités. De cette façon, il est proposé un modèle global d'optimisation de l'identification des capacités multi-niveaux du système à travers l’utilisation d’Algorithmes Génétiques. La faisabilité et l'intérêt d'une telle démarche sont démontrés sur le cas de la machine-outil située à l'usine RENAULT de Cléon / This PhD work has been initiated by Renault, in collaboration with Nancy Research Centre in Automatic Control (CRAN), with the aim to propose the foundation of a generic PHM-based methodology leading to machine health check regarding machine-product joint consideration and facing industrial requirements. The proposed PHM-based methodology is structured in five steps. The two first steps are developed in this PhD work and constitute the major contributions. The first originality represents the formalization of machine-product relationship knowledge based on the extension of well-known functioning/dysfunctioning analysis methods. The formalization is materialized by means of meta-modelling based on UML (Unified Modelling Language). This contribution leads to the identification of relevant parameters to be monitored, from component up to machine level. These parameters serve as a basis of the machine health check elaboration. The second major originality of the thesis aims at the definition of health check elaboration principles from the previously identified monitoring parameters and formalized system knowledge. Elaboration of such health indicators is based on Choquet integral as aggregation method, raising the issue of capacity identification. In this way, it is proposed a global optimization model of capacity identification according to system multi-level, by the use of Genetic Algorithms. Both contributions are developed with the objective to be generic (not only oriented on a specific class of equipment), according to industrial needs. The feasibility and the interests of such approach are shown on the case of machine tool located in RENAULT Cléon Factory

No. of bitstreams: 1 Enidio Ilario.pdf: 4659274 bytes, checksum: 8f1a72841d17232e84a2ec4fa5489782 (MD5) Previous issue date: 2011-12-20 / From a methodological perspective that brings the diagrams as core tools and taking into account that some authors use this methodology as explanatory feature, we intended to demonstrate the suitability of this approach in psychology. In philosophy, for example, the ordine geometrico (according to the order of proof in geometry) has always been widely used as an explanatory feature, putting down deep roots in the field of knowledge. Models, roughly, are abstractions, and always involve a degree of simplification in front of the complexity of the phenomena we want to explain. A classic example of modeling is the Freudian Metapsychology and from it, other projects have developed, for example, in the School of Object Relations the development of complementary models to the Freudian topical, seeking to explain the phenomenology of intersubjectivity and the group. In other fields of psychology, explanatory models were developed, among others, by Kurt Lewin, Piaget, Russian neurologists and psychologists, including Vygotsky, author that foresaw in his time a discipline more general than psychology, now identified in the transdisciplinary project of cognitive science. Common to all, the pursuit of formalization in psychology, however, without achieving success by keeping still open the project. Such authors as well as many of his disciples, are still seeking contributions in areas such as Mathematics, Logic, Structuralism, Systems Theory and more recently, the Theory of Self-Organization and Neuroscience. In this study, renewing the look on the same source and using the Metapsychology as a guide, we seek to develop an original model from the diagrammatic logic. That effort resulted in a topological-vectorial plane formed by two orthogonal axes founders of a plane of immanence with two different and complementary dimensions, the horizontal formed by the polarity individual-social and a vertical formed by the polarity nature-culture. The axes also serve to delimit quadrants, kinds of existential territories that are colonized by conceptual characters and through them the meta-experimentation in the sense of "quasi-empirical", making possible a vectorial analysis. / A partir de uma perspectiva metodol?gica que traz os diagramas como ferramentas centrais e tomando como refer?ncia alguns autores que se utilizam dessa metodologia como recurso explicativo, pretende-se demonstrar a adequa??o dessa abordagem no campo da psicologia. Na filosofia, por exemplo, o more geometrico (de acordo com a ordem de demonstra??o na geometria) sempre foi recurso largamente utilizado, fincando ra?zes profundas no campo do conhecimento. Os modelos, grosso modo, s?o abstra??es e implicam sempre em certo grau de simplifica??o frente ? complexidade dos fen?menos que se quer explicar. Um cl?ssico exemplo de modelagem (ou modelamento) ? a metapsicologia freudiana e a partir dela, outros empreendimentos se desenvolveram, por exemplo, na Escola de Rela??es Objetais o desenvolvimento de modelos complementares ?s t?picas freudianas, buscando dar conta da fenomenologia da intersubjetividade e grupalidade. Em outros campos da psicologia, modelos explicativos foram desenvolvidos, entre outros, por Kurt Lewin, Piaget, neurologistas e psic?logos russos, entre os quais Vygotsky, autor que j? vislumbrava em seu tempo uma disciplina mais geral do que a psicologia, hoje identificada no projeto transdisciplinar das ci?ncias da cogni??o. Podemos dizer que de comum a todos, a busca da formaliza??o na psicologia, contudo, sem lograr sucesso, mantendo o projeto ainda em aberto. Tais autores, bem como muitos de seus disc?pulos, procuraram e ainda procuram contribui??es em ?reas como a Matem?tica, a L?gica, o Estruturalismo, a Teoria dos Sistemas e mais recentemente, a Teoria da Auto- Organiza??o e a Neuroci?ncia. No presente estudo, renovando o olhar sobre as mesmas fontes e tendo a metapsicologia como fio condutor, buscou-se desenvolver uma modelagem original a partir da l?gica diagram?tica. Disso, resultou um plano topol?gico-vetorial, constitu?do atrav?s de dois eixos ortogonais e fundadores de um plano de iman?ncia com duas dimens?es diversas e complementares, a horizontal constitu?da pela polaridade indiv?duo-sociedade e a vertical, constitu?da pela polaridade natureza-cultura. Os eixos tamb?m delimitam quadrantes, esp?cies de territ?rios existenciais, colonizados por personagens conceituais e, atrav?s deles, meta-experimenta??es, no sentido de quase-empiria , tornam-se poss?veis atrav?s de uma anal?tica vetorial.

Este trabalho propõe considerar o processo de formalização legal das transações de terras ocorrido após 1822 - ano da independência do Brasil - como mais uma condição de valorização da terra no Brasil paralelo às classicamente discutidas pela historiografia da História Agrária.O referido processo foi desencadeado pela necessidade de dinamizar o crédito em uma economia pouco monetizada e antecedeu e influenciou o surgimento da propriedade privada no Brasil. Pode ser percebido pela elaboração de leis que visaram promover maior clareza e segurança jurídica nos contratos. Para isso, as mudanças legais não só reformaram e produziram regras e procedimentos contratuais, como o sistema cartorial com a criação dos Cartórios de Registros ao lado dos Cartórios de Notas, integrando suas atividades: o Cartório de Notas passou a controlar a produção dos contratos dentro das formalidades ditadas pela Lei e o Cartório de Registro a lhes dar publicidade. Para concentrar as informações contratuais nos cartórios e disponibilizá-las para o conhecimento público, o Estado paulatinamente desestimulou os negócios feitos por títulos particulares por meio de sucessivas leis, que de forma gradual restringiram a sua segurança jurídica e validade legal. A maior clareza e segurança jurídica produzidas nesse processo tiveram o efeito não só de dinamizar o crédito hipotecário, como também as compras e vendas, catalisando o ganho de valor da terra em condições favoráveis. / The purpose of this dissertation is to assess the process of legal formalization of land purchase after 1822 when Brazil became independent as yet another condition of land valuation in the country, parallel to the reasons that have been traditionally discussed by the historiography on Agrarian History. Such process was triggered by the need to render credit more dynamic in a seldom monetized economy, having both preceded and influenced the rise of private property in Brazil, and included the drafting of laws to promote greater clarity and legal safety for the respective contracts. To this end, the legal modifications not only reformed and produced contractual rules and procedures, but also provided for the establishment of the notarial system and the relevant Real Estate Registry Offices (Brazils registers of deeds) and the Notary Public Offices, whose activities were integrated: the Notary Public Offices were used to control contract drafting according to the formalities set forth by law, whereas the Real Estate Registry Offices were used to render the contracts public. In order to concentrate contractual information at the registries and offices and ensure the public awareness thereof, the State gradually discouraged contractual transactions closed by means of private instruments upon the enactment of successive laws that gradually limited the legal safety and validity thereof. The greater clarity and legal safety brought forth by this process not only enabled mortgage credit to become more dynamic, but also provided for new scenarios in land purchase, thereby resulting in land valuation in favorable conditions.

Human being, as an individual, is a basic element of social organization and plays different roles within different organizations such as family, school, and working setting. During the process of role-taking, individuals are influenced by three factors: personality traits, organization, and interpersonal relationship within working environment. Given that, the purpose of this study is to understand the association of personal, organizational and environmental factors and ¡§perceptions of organizational politics¡¨(POPs). 29 organizations participated in this study and , from which, 1524 valid respondents were collected and analyzed through methods of ¡§factor analysis¡¨, ¡§validity & reliability test¡¨, ¡§correlation analysis¡¨ and ¡§hierarchical regression¡¨. After applying ¡§factor analysis¡¨ of the POPs, it was categorized by three dimensions analysis: ¡§(1) behaviors of superior and subordinate; (2) go along and get ahead; (3) difference between the policies of compensation and promotion and actual practices. The results of this study in summary are: 1.Personal factor has effects on POPs with respect to all its three dimensions. 2.Organizational factor has effects on POPs with respect to all its three dimensions. 3.Environmental factor has effects on POPs with respect to all its three dimensions.

Lacan is an influential figure of 20th Century thought. Being a psychoanalyst, a linguist and at the same time a philosopher, in his theory he combines all three of these disciplines. Even in his later works, he tried to combine his theory with mathematical formalization. His theory influenced three important political thinkers: Laclau, &amp / #381 / i&amp / #382 / ek and Badiou. The purpose of this dissertation is mainly to examine Lacan&rsquo / s thought and its impasses which could be found especially in the political applications of his theory. First I start with a critical reading of Lacan&rsquo / s own works. I try to figure out the idealizations, presuppositions and blind spots hidden in his work. I develop my critical reading by focusing on the works of Laclau, &amp / #381 / i&amp / #382 / ek and Badiou. The main argument of this dissertation is, such a critical reading of these philosophers will lead us to a general questioning of Lacan&rsquo / s theory and the legitimacy of its applications. Lacan&rsquo / s use of the impossibility as a founding principle and his passion for formalization cause several idealizations, like the idealization of the neutrality of the signifier, the idealization of the non-represented and so on. These problems are extended and transformed into other ones in his disciples&rsquo / works. For Laclau, the problem is transformed into a purely content-free understanding of elements of democracy which ends up with paradoxical results. For &amp / #381 / i&amp / #382 / ek and Badiou, because of their insistence on a political theory based on the impossible real, their subversive theories end up with a theory which take the form of messianic discourses. What I propose is a reconsideration of the role of the theory on the understanding of human reality: in principle every theory excludes some portions of the richness of human life-world, therefore every theory must have a retrospective and critical stance against its own founding principles. This cannot be done by formalized theories which keep the formal structure of itself untouchable.

Šiame darbe analizuojama mobilaus ryšio sistema. Yra tariama, jog tinkle egzistuoja dviejų tipų įrenginiai: mobilūs ir fiksuoti. Fiksuoti įrenginiai yra visados įjungti ir prijungti prie tinklo. Fiksuoti įrenginiai, tai mobiliosios palaikymo stotys (MPS) ir duomenų bazė. Mobilūs įrenginiai (mobilūs kompiuteriai) gauna duomenis iš duomenų bazės, tarpininkaujant palaikymo stotims. Mobilūs kompiuteriai prisijungia ir persijungia prie skirtingų MPS, priklausomai nuo jų skleidžiamo signalo stiprumo. Visi veiksmai atliekami nuosekliai, nepertraukiant galutinio vartotojo darbo. Kuriant tokių sistemų programinius modelius pirmiausia reikia jas išanalizuoti ir suformalizuoti. Viena iš formalizavimo kalbų – PLA, neseniai buvo išplėsta, kad gal���tų aprašyti dinamines sistemas. Šiame darbe supažindinama su naujai išplėsta formalizavimo kalba (dynPLA). Ji naudojama mobilaus ryšio sistemos specifikavimui bei tikrinama ar formalizavimo kalbos išplėtimų užtenka aprašyti minėtąją sistemą. Pasiūlyti dynPLA formalizavimo kalbos patobulinimai bei pateiktas sistemos modelio specifikacijos pavyzdys. / The mobile computing system will be analyzed in this work. It is assumed that network consists of two types of devices: mobile and fixed. Fixed devices are always on and always connected to the network. These devices include, but are not limited to database servers and mobile support stations (MSS). Mobile devices access data from database. They connect and reconnect to different MSS depending on the signal strength. All of this is done seamlessly to the end user and the data transfer is not disturbed. When planning to implement such system in programming language, the first step is analyzing and formalizing it. One of the formalization languages – PLA, was recently extended for the sole purpose of formalization of dynamic systems. This work, “The Usage of dynPLA Formalism for Modeling of Mobile Computing System” covers the usage of new extended formalization language (dynPLA) for mobile computing system, analyzing if dynPLA extensions are sufficient for formalizing the said system. Also some improvements for the dynPLA formalization language will be suggested and the example of the mobile computing system will be given.

The diverse discussions around the Minimum Living Wage have been very controversial and constant over the past decades due to the economic, social and political context inwhich  Peru  was  immersed.  However, these discussions have reduced its recurrence overthe past years as a result of various factors, such as the development of labor rights andimprovement of the economic situation.However, it is extremely relevant to understand the importance of the role of the Minimum Living Wage and the implications it may have over the workers. That is why in the present exposition there will be a presentation  of the opposing positions regarding the impact–positive or negative– of the existence of a Minimum Living Wage on workers. / Las discusiones alrededor de la Remuneración Mínima Vital han sido muy polémicas yconstantes en las décadas pasadas debido alcontexto económico, social y político en el queel Perú se encontraba inmerso. Sin embargo, esas discusiones son cada vez menos recurrentes en la actualidad como resultado de la interacción de diversos factores, tales como eldesarrollo de los derechos laborales y la mejora de la situación económica.No obstante, es sumamente relevante entender la importancia del rol que tiene la Remuneración Mínima Vital y las implicancias de su fijación para los trabajadores. Es por ello que, en la presente exposición, se presentarán posiciones encontradas respecto al impacto –positivo o negativo– que la determinación de un salario mínimo puede tener en los trabajadores.

Esta dissertação tem como objeto as mudanças no emprego e no trabalho dos cortadores de cana-de-açúcar da agroindústria canavieira de Alagoas. Na década de 1990, no bojo do processo de reestruturação produtiva do setor sucroalcooleiro, a informalidade do emprego é interditada com o processo de formalização, no qual passa a se estabelecer contratos diretos entre capital e trabalho, e ao mesmo tempo, ocorre um processo de intensificação do trabalho manual dos cortadores de cana. A partir deste cenário, busca-se entender como a emergência da formalização do trabalho canavieiro se relaciona com os processos contemporâneos de precarização do trabalho. Para tanto, realizou-se uma clarificação dos conceitos de precariedade e precarização a partir das perspectivas sociológicas que vêm investigando as mudanças contemporâneas no mundo do trabalho. Parte-se do pressuposto de que as formas de trabalho na agroindústria canavieira configuram-se a partir de uma histórica e estrutural precariedade. Assim, primeiramente, retorna-se ao passado a fim de levantar pistas para entender os significados que a precariedade do trabalho canavieiro assume ao longo do século XX, e localizar onde estão presentes aspectos de precariedade referentes ao emprego e ao trabalho. Por conseguinte, realizou-se uma pesquisa de campo com trabalhadores canavieiros da parte norte-serrana da Zona da Mata de Alagoas, utilizando-se de entrevistas em profundidade, com o intuito de produzir dados para conhecer o que ocorre, contemporaneamente, com as dimensões do emprego e do trabalho nesse processo de formalização da atividade. Essa ampla revisita às formas emblemáticas de trabalho canavieiro entre o passado e o presente, permitiu argumentar que o processo de formalização não impediu que novos processos de precarização atingissem o trabalho canavieiro. Nesse sentido, a evolução do emprego e do trabalho nas regiões canavieiras alude a um processo de institucionalização da intermitência e da intensificação da atividade, isto é, a própria precariedade do emprego e do trabalho foram institucionalizadas e legitimadas, levando a uma atualização de seus efeitos sob a forma de inseguranças socioeconômicas, que atingem as possibilidades de produção dos meios de vida dos canavieiros, e repercussões à saúde, degradando a força de trabalho. / In this dissertation we intend to describe the changes in the employment and work of sugarcane cutters in the agro-industry of Alagoas. The productive reorganization of the sugarcane industry in the 1990’s implicated the end of the informal employment, due to the process of formalization by which direct contracts between capital and labor were established. Moreover, the manual work of the sugarcane cutters intensified significantly. We try to comprehend how the emergence of the formalization of their work relates to the contemporary processes of precarization of work. Therefore, we intend to find an explanation for the concept of precariousness, starting from the sociological perspectives derived from research on the contemporary changes in labor relations. We specifically start from the presupposition that the forms of work in the sugarcane industry are arranged in relation to a historical and structural precariousness. Therefore, we first look back at the past in order to find indications to understand the meanings that the precariousness of the sugarcane labor takes on in the course of the 20th Century, and to localize the aspects of precariousness regarding the work and employment. Consequently, we carried out fieldwork involving sugarcane cutters from the northern highlands of the Zona da Mata in Alagoas; making use of in-depth interviews, with the intention to gather information on the work and employment in this enduring process of formalization. Differences between the past and present situation of the sugarcane work makes it possible to argue that the process of formalization facilitated the emergence of precariousness. In this sense, the evolution of the work and employment in the sugarcane regions alludes to a process of institutionalization of intermittence and intensification of the work, namely, the precariousness of work and employment was institutionalized and legitimized, leading to effects of socio-economic insecurities which affect the means of life of sugarcane cutters, as well as repercussions for their health, degrading the workforce.

The research problem we propose to reflect about concerns the constitution of language and of memory in the metallic materiality. We focus, in our work, on the fact that technologies are produced by man, under certain social and historical conditions. The fact that language may be conceived externally to man in informatic media -, does not mean that it is in a transcendental plan in relation to the subject, to the discourse. Furthermore, what is from the historical subject belongs as well to the machine, to the technique. Our point of view, thus, is that technique and man, language and subject should be thought as mutually constituted and not as opposite elements, which would exclude each other. In this way, we propose, under the perspective of French Discourse Analysis, a study of language that takes in consideration that language and discourse are mutually constituted. Our aim is to emphasize that the order of language is not independent from the order of discourse. By observing the working of formalization and of the categories of time and space in Google, we infer that there is a double movement of sense constitution in the metallic materiality: on the one hand, a movement that searches the completeness of language, which would be possible through the constitution of a memory with a large capacity of storage; in this memory, senses would be frozen in space and time, so that the irruption of other significations would not become possible. On the other hand, incompleteness is constituted in the simulation of completeness itself. We think incompleteness is structured by the excess of information that circulates in Web. This excess is a sign that there is ever something to be said, since language is not a representation of the world. / O problema de pesquisa sobre o qual nos propomos refletir tem como foco a constituição da linguagem e da memória na materialidade metálica. Chamamos atenção, em nosso trabalho, para o fato de que as tecnologias são produzidas pelos homens, como frutos de certas condições sócio-históricas. O fato de a linguagem poder ser concebida exteriormente ao homem - nos meios informáticos -, não significa que ela esteja em um plano transcendente ao do sujeito, do discurso. Assim, o que é do sujeito histórico também faz parte da máquina, da técnica. Nosso ponto de vista, portanto, é de que técnica e homem, língua e sujeito devem ser pensados enquanto mutuamente constitutivos e não enquanto elementos opositivos, os quais se excluiriam uns aos outros. Nessa perspectiva, propomos, a partir da Análise de Discurso de linha francesa, um estudo da linguagem que vise a uma relação de recobrimento entre língua e discurso. Nosso objetivo é o de salientar que a ordem da língua, do formal não é independente da ordem do discursivo. A partir da observação do funcionamento da formalização e das categorias de tempo e de espaço no site de busca Google, inferimos que há um duplo movimento de constituição de sentidos na materialidade metálica: por um lado, aquele que busca a completude da linguagem, por meio da constituição de uma memória com grande capacidade de armazenamento de dados, na qual os sentidos seriam congelados no espaço e no tempo, de modo a não dar abertura para a irrupção de outras significações. Por outro lado, é, na própria simulação da completude, que se constitui a incompletude. Esta, para nós, vem a ser estruturada pelo excesso de informação que circula na Internet. Este excesso é a marca de que sempre há o que dizer, tendo em vista que a linguagem não é uma representação do mundo.
