Analýza vyboulování trubek kapalinou / Analysis of Tube Bulging Process

Zdráhala, Radim January 2017 (has links)
The diploma thesis is focused on the analysis of the behavior of the thin-walled tubular test specimen during the technological test of the liquid draining of the tubes. The test specimen ‘in the form a tube was made of austenitic stainless steel 17 240 (1.4301, X5CrNi18-10). During the experiment, the radial expanding tool was quasi-statically charged by the internal fluid pressure. In the introductory part, the thesis focuses on the stress-strain description of the method of tube bulging and possible ways of detecting the strain of material during forming. The experimental part is primarily focused on the analysis of the test sample that was obtained from the experiment. Theoretical approaches were used to analyze the real test sample to detect strain and stress in material, numerical simulation of the bulge process and 3D ATOS scanning device, which helped clarify behavior tube during bulging process. At the end of the thesis is proposed possible design of the tool. This modification should contribute in the future to the full functionality of the radial expanding tool, or the bulging of the tube by liquid.

Sabe-se que o Direito Positivo é todo baseado na elaboração das leis, as quais são realizadas pelo Poder Legislativo. Dessa forma, o Direito se apóia em muito no conjunto de leis vigentes, as quais devem ser cumpridas por toda a sociedade e aplicadas pelos operadores do Direito em geral, notadamente pelo Poder Judiciário. Como a lei é uma fonte do Direito, inspiradora da forma de comportamento da sociedade em geral, é de suma importância estudarmos quando a lei em geral possui algum vício insanável decorrente do excesso ou desvio de poder na atuação dos parlamentares que a elaboraram. Muito embora o exercício da atividade legislativa seja uma das formas de o Estado expressar a sua soberania, hodiernamente em muitas oportunidades temos nos deparado com a elaboração de leis que não atendem os interesses da coletividade em geral. Assim, a atividade parlamentar, que deveria ser exercida em nome do povo e para representar os legítimos interesses do próprio povo, muitas vezes é realizada de forma distorcida para privilegiar os interesses de somente uma pessoa, uma classe ou categoria de pessoas em detrimento do interesse público e do interesse social. As leis elaboradas com o fito de beneficiarem somente uma ou algumas pessoas em detrimento do interesse popular, da sociedade em geral, devem ser reconhecidas como viciadas pelo desvio ou excesso de poder na sua elaboração. O parlamentar desvia-se de suas funções para as quais recebeu poderes da população e age visando... / In the present thesis it was approached the study of the practice of proper legislative acts - law in formal sense - with diversion or excess of power, it was tried to define how and when the State is obligated to remedy the material and moral damages, caused to the individual in such situation, as well as discuss about the legislator's personal responsibility, who has contributed for the elaboration of laws in this sense. It's known that the Positive Law is all based in elaboration of laws, which are carried out by the Legislative Power. In this way, the Law is highly supported on the set of valid laws, which must be obeyed by the society in a whole and enforced by the Law operators in general, mainly by the judiciary. As the law is a source of the Law, which inspires the society's behavior in general, it is extremely important to study when the law, in general, possesses some irremediable failing resulting from the excess or deviation of power in the members of parliament's performance, who had elaborate it. Even though the legislative activity exercise is one of the ways that the State has to express its sovereignty, currently we have faced, in many opportunities, law's elaboration, which doesn't fit the society's interests in general. Thus the parliamentary activity, which was supposed to be exerted in the people's name and to represent people's legitimate interests, many times has been accomplished in a deviated way in order to privilege only one person, class or category of people's interests to the detriment of public and social's interests. The laws, which are elaborated with the intent of benefit only one or some few people to the detriment of the public interest, of the society in general, should be recognized as corrupted by the diversion or excess of power in its elaboration. The member of the parliament deviates from the duties which he received power...(Complete abstract click elctronic access below)

[en] THE STATEMENT OF AN UNFAVOURABLE OPINION IN BRAZILIAN PORTUGUESE AND ITS INSERTION IN THE STUDIES OF PORTUGUESE AS SECOND LANGUAGE FOR FOREIGNERS PL2E / [pt] A ELABORAÇÃO DA OPINIÃO DESFAVORÁVEL EM PORTUGUÊS DO BRASIL E SUA INSERÇÃO NOS ESTUDOS DE PORTUGUÊS COMO SEGUNDA LÍNGUA PARA ESTRANGEIROS PL2E

PATRICIA MARIA CAMPOS DE ALMEIDA 28 May 2007 (has links)
[pt] Atualmente há, na área de ensino de língua estrangeira, a compreensão de que um bom usuário de uma LE deve desenvolver um conjunto de competências, tais como: gramatical, sociolingüística, discursiva e estratégica. A necessidade de se considerar todas essas competências advém do fato de que o sucesso em uma comunicação real e intercultural não pode ser garantido apenas com base no conhecimento lingüístico (Meyer, 2002). Procuramos investigar como elaboramos a emissão da opinião desfavorável, buscando verificar que elementos lingüísticos compõem-na e em que contextos emitimos tal tipo de opinião. Objetivamos, portanto, delinear um modelo de quadro que nos permita compreender as estratégias empregadas no ato de elaborar a opinião desfavorável. Foram fundamentais para esta pesquisa os conceitos advindos da Gramática sistêmicofuncional e referentes ao contexto, além de conceitos do campo da Pragmática. Os dados da pesquisa - obtidos após aplicação de um Discourse completion test - permitiram-nos identificar quatro categorias dentro das quais foram distribuídas as formas de elaboração do ato de emitir uma opinião desfavorável, a saber: 1. Opinião desfavorável direta; 2. Opinião desfavorável indireta; 3. Falsa opinião positiva; 4. Não manifestação de opinião. Além disso, foram identificadas formulações periféricas que, ao acompanharem as categorias listadas, têm como objetivos amenizar o impacto da opinião desfavorável e salvaguardar a face dos interlocutores. A pesquisa demonstrou que se faz necessário - no contexto de ensino de língua estrangeira - ter um conhecimento dos diferentes atos de fala, dentro dos quais inclui-se o ato de opinar desfavoravelmente a fim de que possamos nos comunicar adequadamente em situações reais de uso. / [en] Nowadays, in the field of foreign language (FL) teaching, it is understood that a good user of an FL should develop a group of competences such as grammatical, sociolinguistic, discoursive and strategic competences. The need to consider all of them derives from the fact that the success in a real intercultural communication cannot be assured through linguistic knowledge only (Meyer, 2002). This thesis investigates how an unfavourable opinion can be expressed and also which linguistic elements are used and in which contexts this kind of opinion is given. Our aim, thus, is to propose a model of table that provides an understanding of the strategies used in the act of stating an unfavourable opinion. The concepts from systemic functional Grammar related to the context, as well as those of Pragmatics, were paramount to this research. The data - gathered by means of a Discourse completion test - allowed us to identify four categories that classify the ways of giving an unfavourable opinion, namely: 1. direct unfavourable opinion; 2. indirect unfavourable opinion; 3. false positive opinion; 4. absence of opinion. Furthermore, peripheral formulations were identified. Coexisting with the categories listed above, they aim at diminishing the impact of an unfavourable opinion and preserving the interlocutors´ face. The research showed that - in the context of foreign language teaching - the knowledge of the different acts of speaking is necessary, including the act of stating an unfavourable opinion, so that proper communication can be established in real-life situations.
