1. Control of strain in a flexible beam using Ni-Ti-Cu shape memory alloy wire actuators
In this paper the development of an experimental test bench to analyze and control the strain of a flexible aluminum beam subjected to external disturbances is described. In the proposed platform, strain-gauges are used to measure the strain of the beam in a single cantilever mode while Ni-Ti-Cu Shape Memory Alloy (SMA) wires are used as force actuators. Dat

3. DevC: uma linguagem de suporte ao desenvolvimento concorrente de device drives e modelos de controladores de entrada e saÃda
Modern electronic products incorporate several features, combining mobility, computational power, a great capacity for communication and facility for interfacing. Nevertheless, integrating such functionalities increases the complexity of the design. The design of such products includes an embedded system that implements their functionalities in a combined so

5. Desenvolvimento de um atuador de posição baseado em liga de memória de forma com resfriamento forçado. / Development of a position actuator based on a shape memory alloy with forced cooling.
Shape Memory Alloys (SMA) consist of a group of metallic materials that demonstrate the ability to return to some previously defined shape when subjected to the appropriate thermal cycle, due to shift in the materials crystalline structure. The change that occurs within SMAs crystalline structure is not a thermodynamically reversible process and results in h

6. PROJETO E IMPLEMENTAÇÃO DE UM CONTROLE MODULAR HCC PARA INTEGRAÇÃO DE FONTES ALTERNATIVAS DE ENERGIA / DESIGN AND IMPLEMENTATION OF A MODULAR HCC CONTROLLER TO INTEGRATE ALTERNATIVE SOURCES OF ENERGY
The experience of electric energy shortage in 2001 demonstrated that our dependence almost exclusively on hydroelectricity could fetch great problems to Brazil. Thus being, the existence of trustworthy alternatives of energy must exist, at the very least, as a reserve. For this reason, the perspective of decentralizing the energy production as a form of prom

8. PROCESSING OF SUBJECT-VERB NUMBER AGREEMENT IN SENTENCE PRODUCTION / PROCESSAMENTO DA CONCORDÂNCIA DE NÚMERO ENTRE SUJEITO E VERBO NA PRODUÇÃO DE SENTENÇAS
The processing of subject-verb number agreement in sentence production by speakers of the standard dialect of the Brazilian Portuguese is investigated. The dissertation focuses on attraction errors and its main aim is to identify the factors that interfere in agreement processing and to provide a psycholinguistic account, which is compatible with assumptions

12. Modalities of Interleukin-7-Induced Human Immunodeficiency Virus Permissiveness in Quiescent T Lymphocytes
The metabolic and cell cycle status of primary T lymphocytes conditions their susceptibility to human immunodeficiency virus (HIV) and HIV-derived vectors. While in fully quiescent T lymphocytes the reverse transcription and nuclear import of these retroelements are impaired, leading to an abortive infection, various stimuli can induce a state of virus permi
