Avaliação da qualidade final de juntas dissimilares de ligas de alumínio 2024-6056 e 7075-6056 soldadas por FSW - friction stir welding
(Universidade Federal de São Carlos, 2006-03-31) Potomati, Fernanda; Alcântara, Nelson Guedes de; https://lattes.cnpq.br/3123107570992184; https://lattes.cnpq.br/1449729356742076
The aeronautic industry has been studying the FSW (Friction Stir Welding) process since its development by TWI (The Welding Institute), in 1991. Nowadays it has been used in the airplanes fuselage of the Eclipse Aviation Co. and in non structural parts of the Airbus A380, in recent times started. Thus, the knowledge on welding of aeronautic aluminum alloys is very important to give safety in the use of the process and to development of new possibilities of joints for these alloys. Dissimilar welding allows some freedom on project design i.e. possibilities to join materials with different properties. The challenge of this work is to join materials with different mechanical properties using FSW, which is based on mechanical deformation. For this aim, dissimilar joints, 2024-T351 to 6056-T4 and 7075-T76 to 6056-T4, have been welded. The rotational speed was maintained constant and the travel speed was variable. The best parameters were identified according to the final quality of the welds after microstructural analyses and mechanical properties evaluation (tensile and microhardness tests). The analyses of the thermal cycles and forces developed during the weld, and the evaluation of the quality weld determine the best parameters that can produce a better combination between heat input and the best weld quality. It is concluded that the mechanical properties of the dissimilar joints improve with increasing weld travel speed and when the 6056 alloy is placed in the advancing side of the joint.
Canal virtual de tempo-real

Due to the increase of general purpose operational systems support for real-time applications and by the increasing number of network interfaces with multiple communication technologies present in one single computational device, a middleware, with real-time characteristics, was designed and developed. This middleware encapsulates these communication technologies and protocols in order to improve fault tolerance and consequentially comply with deadlines for message transmission through connectivity options supply. Moreover, the Real Time Virtual Channel provides a virtual access point address mechanism, where each address maps a set of real access points from the consumer endpoint. For the translation of these addresses in real access points, name servers, known as Brokers, were also implemented.
A teoria do sentido em Deleuze
(Universidade Federal de São Carlos, 2006-03-31) Lopes, Luiz Manoel; Ferraz Júnior, Bento Prado de Almeida
The proposal of this work is to study the theory of sense in Deleuze inserted in the questions that reverberate on the contemporaneous philosophical field. Our route will follow the statements of Deleuze on his book Logic of Sense , especially when he detaches that this theme was thought by three different ways: the first, as lekton, by the Stoics on the III century B.C.; the second, as complexe significable, by Gregori di Rimini, on the XIV century; the third as obektiv, by Meinong, on the XIX century. When Deleuze thinks about his theory of sense, he introduces the sense as event.. Our study will start from the rosen questions by Meinong and how they have their origin on the paradox of the representation without object rosen by Benhard Bozano , which allows us to affirm that such paradox is at the origins of the phenomenology and in the analytic philosophy. The theory of the sense of Deleuze will be presented like being out from these two current contemporaneous philosophies.
Uso do Senso Comum na detecção de diferenças culturais no contexto do Projeto OpenMind CommonSense no Brasil

Knowing what is specific about each culture would be helpful to perform cross cultural communication, because different cultures have different notions of how to begin and develop conversations. Due theses difficulties in differences in cultural norms, we are working to provide to computers this knowledge, since computer environment can allow communication across distance and across cultures. In order to provide to computers cross cultural knowledge, we have collected large knowledge bases representing Common Sense knowledge because we believe that Common Sense knowledge can give some guidelines about different cultures. In our research, we have used bases containing sentences describing common sense knowledge of people and everyday activities, beliefs and values collected from volunteer Web contributors. Furthermore, we describe experiences with these knowledge bases, and we are proposing software which automatically searches for cultural differences related to eating habits, alerting the user to potential differences among cultures. In this way, we hope that our work will contribute to software that takes better account of such differences, and fosters inter-cultural collaboration
