25. Simulation of non-periodics flows using the fourier pseudo-spectral and immersed boundary methods / Simulação de escoamentos não-periódicos utilizando as metodologias pseudo-espectral e da fronteira imersa acopladas
Modern engineering increasingly requires the comprehension of phenomena related to combustion, aeroacustics, turbulence transition, among others. For these purposes the Computational Fluids Dynamics (CFD) requires the used high order methods. One of these methods is the Fourier pseudo-spectral method, that provides an excellent numerical accuracy, and with t

26. Simulation of non-periodics flows using the fourier pseudo-spectral and immersed boundary methods / SimulaÃÃo de escoamentos nÃo-periÃdicos utilizando as metodologias pseudo-espectral e da fronteira imersa acopladas
Para compreender fenÃmenos relacionados à combustÃo, aeroacÃstica, transiÃÃo a turbulÃncia entre outros, a DinÃmica de FluÃdos Computacional (CFD) utiliza os mÃtodos de alta ordem. Um dos mais conhecidos à o mÃtodo pseudo-espectral de Fourier, o qual alia: alta ordem de precisÃo na resoluÃÃo das equaÃÃes, com um baixo custo computacional. Es

27. Development of a computacional model for calculations of absorved dose to organs and tissues of the human body in situations of accidental exposures / Desenvolvimento de um modelo computacional para cÃlculos de dose absorvida em ÃrgÃos e tecidos do corpo humano nas situaÃÃes de exposiÃÃes acidentais
Exposure to a radiation field may be of medical, environmental, occupational or accidental nature, but in all cases the main objective is the determination of the whole body absorbed dose or the distribution of absorbed dose to specific organs and tissues. In recent years, estimates of the radiation absorbed dose in the human body have become more accurate d

28. Modelagem e otimização de um robô de arquitetura paralela para aplicações industriais. / Modeling and optimization of a parallel architecture robot for industrial applications.
This work is about the study of parallel architecture robots, focusing in modeling and optimization. No physical prototypes were built, although the virtual models can help those willing to do so. After searching for an application that could benefit from the use of a parallel robot, another search was made, this time for the right architecture type. After s

29. Método da fronteira imersa aplicado à modelagem matemática e simulação numérica de escoamentos turbulentos sobre geometrias móveis e deformáveis / Immersed boundary method applied to mathematical modeling and numerical simulation of turbulent flow over moving and deformable boundaries
A modelagem matemática de escoamentos turbulentos sobre geometrias complexas móveis possui uma extensa área de aplicações práticas e por isso ocupa lugar de destaque nas pesquisas recentes em engenharia. Uma linha proposta para o tratamento numérico deste tipo de problemas são os métodos de fronteira imersa. Esta metodologia, ainda em desenvolviment

30. Um middleware reconfigurÃvel para redes de sensores sem fio
The WSN attractivity for environment conditions monitoring and to be the bridge between the physical and virtual world has been increasing due to the advances in the micro-electronics, which enabled the production of several sensor types like illumination, humidity, temperature, smoke, radiation, acoustic, seismic, etc. in a chip that processes the signal an

31. Automatic formation and analysis of multi-agent virtual organization
Virtual organization refers to the temporary teaming of enterprises. By sharing physical, human and knowledge resources via information technologies, a virtual organization enables member enterprises to share skills, costs, access to one another's markets and, at the same time decrease the risk of investments. To realize this new generation of business model

32. Coffee Machine: a social virtual environment for informal collaboration.
Human beings need to collaborate with each other whether the goal is to develop a jointly collaborative task, to maintain existing social relationships or to provide opportunities to create new ones. These collaborations can be essentially classified either in formal or informal collaborations. These are two distinct but complementary forms of collaborations

33. Auralização : tecnicas de modelagem e simulação binaural de ambientes acusticos virtuais
Auralization is a term used to signify the techniques that render audible a sound field through the mathematical or physical modeling of the sound source, the acoustic space and the listener. The present work aims to analyse fully computed process of modeling to the constitution of virtual acoustics environments that can be implemented and interactively simu

34. Mathematical modeling for three-dimensional fluid-structure interaction problems / Modelagem matemática tridimensional para problemas de interação fluido-estrutura
A modelagem matemática e a simulação numérica de escoamentos turbulentos tridimensionais ao redor de geometrias complexas móveis constituem um dos grandes desafios da engenharia moderna. A discretização de domínios tridimensionais costuma exigir grande capacidade de armazenamento e processamento de dados que, se somados aos freqüentes refinamentos l

35. Proposta de estrategias de marketing para o lancamento do ensino a distancia, na Universidade Regional de Blumenau - FURB
The effects of globalization can be observed in all contexts: Countries, economy, companies and culture. With this in mind, human beings are supposed to widen their limits by a continuous search for self development. Following this model, education is then considered something permanent in our lives. So, the University needs to review and broaden the teachin

36. Prototipação de um torno CNC utilizando realidade virtual. / Prototyping of a lathe CNC using virtual reality.
The aim of this work is the developing of a procedure for the implementation of a CNC lathe prototype using virtual reality, focusing mainly in its interlocking system (functionality) and its geometrical model (physical design). This work starts with a revision about the using of VR in many areas including industry, and afterwards refers briefly on the progr
