1. Investigation of dynamic instability of three plates switch under step DC voltage actuation using modified couple stress theory
Abstract In this paper dynamical instability of three-layer micro-switch under DC voltage actuation has been studied. Recent studies have used the classical beam theory while leaving out the length scale parameter. In this paper dynamic behavior of the switch has been investigated based on couple stress theory and considering the length scale parameter. To t

2. A taxa de câmbio no centro da teoria do desenvolvimento
This paper presents the main ideas of structuralist development macroeconomics – the theory behind new developmentalism. Its focus is on the exchange rate that is positioned for the first time in the core of development economics. Economic theory usually views the exchange rate as a short term problem to be discussed in open macroeconomics. Structuralist d

3. Escalabilidade de fonte de alimentação chaveada para uso em eletrodomesticos / Switch mode power supply scalability fo use in home appliances
This work describes the development of a switch mode power supply to be used at home appliances, capable to deliver three outputs with voltage and power different levels, changing a minimum number of components between them. At the first part of the work is presented the application of the power supply and its needs, followed by the specifications and choose

4. Automatic generation and evaluation of transistor networks in different logic styles / Geração automática e avaliação de redes de transistores em diferentes estilos lógicos
Currently, VLSI design has established a dominant role in the electronics industry. Automated tools have enabled designers to manipulate more transistors on a design project and shorten the design cycle. In particular, logic synthesis tools have contributed significantly to reduce the design cycle time. In full-custom designs, manual generation of transistor

5. BIFUEL CONVERSION OF THERMAL POWER PLANTS UNDER UNCERTAINTY: A REAL OPTIONS APPROACH / CONVERSÃO DE TERMELÉTRICAS PARA BI-COMBUSTÍVEL EM AMBIENTE DE INCERTEZA: UMA ABORDAGEM POR OPÇÕES REAIS
In Brazil, despite the predominant participation of hydro power plants, some years ago, due to Thermo Power Priority Program (PPT), a large number of Natural Gaspowered plants were implanted. A lot of uncertainties are imposed to the players in the Brazilian Power Market, and one more risk arises: the Natural Gas offer. The bi-fuel conversion arises as an op

6. Descarbonization of dominant energetic regime : perspectives on economy of hydrogen in Brazil / Descarbonização do regime energetico dominante : perspectivas para a economia do hidrogenio no Brasil
In the last decades technological development of energy sector has evolved in connection with environmental worries, in as much as these ones have also influenced options for some specific energetic technologies. Current context is characterized by fossil fuel and intemal-combustion engine, such reality presents steady increase of energy consume and brings d

7. VALUATION OF XTL PLANTS PROJECT INVESTMENT BASED ON REAL OPTIONS THEORY / AVALIAÇÃO DE PROJETOS DE INVESTIMENTO EM PLANTAS XTL UTILIZANDO A TEORIA DE OPÇÕES REAIS
The objective of this dissertation is to value the operational flexibility that a GTL plant can offer at the entrance of the productive process where multiples inputs can be used as row material. Different products also can be produced. The real options theory is considered by the author as the most indicated financial methodology to value theses flexibiliti

9. Proposal and performance analysis of a combined input and output queuing packet switch / Proposta e analise de desempenho de um comutador de pacotes com enfileiramentos na entrada e na saida
A QoS (Quality of Service) provisioned CIOQ (Combined Input Output Queuing) switch using crossbar structure with m parallel lines per output port is proposed in this work. The packets at input buffers are transferred to the output buffers by means of mxN internal lines. Since all internal lines have the same speed as external links, no internal clock speedup
