14. Absorption spectrum of the ortho-betaine in Water: a Study Theoretical Method using Sequential Monte Carlo/Mechanics Quantum / Espectro de Absorção da Orto-betaína em Água: um Estudo Teórico usando o Método Seqüencial Monte Carlo/Mecânica Quântica
Using sequential Monte Carlo simulation and quantum mechanics calculations(S-QM/MM) based on the TD-DFT methods we have been used to study the solvatochromic shift of the orto-betaine in water. Statistically uncorrelated configurations have been obtained from MC simulations with unpolarized and in-solution polarized solute. To account for the solute electron

17. Sínteses, caracterizações e estudo de pontos quânticos de calcogenetos de cádmio
CdS, CdSe, CdSxSe1-x and Cd1-xMnxS quantum dots were successfully grown in the glass matrix SNAB [40SiO2.30Na2CO3.1Al2O3.29B2O3 (mol%)] synthesized by the Fusion Method, when subjected to certain thermal treatment. The glass transition temperature (Tg) of the glass matrix SNAB was found by Differential Scanning Calorimetry (DSC) in order to set the temperatu

19. Rede serial para comunicação de dados e controle em sistema embarcado: estudo de implementação da ISO 11783 / Serial control and communication data network on embedded systems: study of implementation of ISO 11783
As redes digitais demonstraram ser uma solução eficaz em automação. A conexão de diferentes módulos de diferentes fabricantes em um único barramento para a troca de dados e controle é um desafio para a indústria brasileira de máquinas agrícolas, apesar desta tecnologia estar consolidada em automóveis, aeronaves e em chão de fábrica. As vantagen

23. Aquarius II â Uma plataforma para desenvolvimento de sistemas dinamicamente reconfigurÃveis baseada no sistema operacional uCLinux
The programmable logic devices, FPGAs (Field Programmable Gate Arrays) have been used for a long time as tools for digital circuits prototyping. However, this reality has changed since the computational power of these devices increased and cost decreased. Besides, the FPGAs in use nowadays consume less energy than a conventional CPU to do the same work. Anot

24. Geração de especificações executáveis para o projeto de módulos para sistemas em "Chips"
The increasing demand for electronic components is driving the integrated circuit market to an unexpected growth. In the about two to four years it will be possible to find circuits composed of a billion transistors. This capacity of integration is the responsible for the emergence of a new concept, System-on-a-chip (SoC), in which a complete computational s
