2. Maximum profit cogeneration plant - MPCP: system modeling, optimization problem formulation, and solution
The well-known CGAM optimization problem was formulated to serve as a benchmark for comparison of different thermoeconomic methodologies. The CGAM cogeneration plant produced 30 MW of power and 14 kg/s of saturated vapor at 20 bar. The objective function was the total cost rate of the system, related to thermodynamic variables and installation costs. Because

3. IDENTIFICATION OF THE BEHAVIOR OF TEMPERATURE MAIN RECTIFIER OF A DIESEL-ELECTRIC LOCOMOTIVE / IDENTIFICAÇÃO DO COMPORTAMENTO DA TEMPERATURA DO RETIFICADOR PRINCIPAL DE UMA LOCOMOTIVA DIESEL-ELÉTRICA
In this dissertation, we explore the application of the Theory of System Identification to develop a mathematical model that represents the behavior of the electrical current rectifier used to power the traction motors of a locomotive diesel-electric, based on mathematical manipulation of its temperature data. It was developed an ARX model and, using the aid

5. Amonização de feno de Coast-cross. / Ammonization in coast-cross hay.
This experiment was accomplished in the Animal Nutrition and Pastures Department in the Institute of Animal Science of the Rural Federal University of Rio de Janeiro. The effects of increasing levels of urea addition were evaluated on the chemical-bromatologic and microbiologic composition of Coast-cross hay. The hay was treated with 5 levels of urea (0, 0,5

6. AVALIAÇÃO E REFORÇO DAS CONDIÇÕES DE ESTABILIDADE DE TENSÃO EM BARRAS DE TENSÃO CONTROLADA POR GERADORES E COMPENSADORES SÍNCRONOS / VOLTAGE STABILITY ASSESSMENT AND ENHANCEMENT IN VOLTAGE-CONTROLLED BUSES BY SYNCHRONOUS GENERATORS AND COMPENSATORS
After the incidence of some voltage collapses in the energy transmission systems in the world, the voltage security became an issue of great interest in the last years due to the importance of its impact. The phenomenon of voltage stability is due to the excessive active and reactive power flow in the electrical transmission network and has been associated w

7. Temporal and spatial variability of rainfall and water balance in the state of Rondônia, Brazil: characterization tendency analysis / Variabilidade temporal e espacial das chuvas e do balanço hídrico no estado de Rondônia: caracterização e análise de tendência
Amazon deforestation rate has been significant, resulting in a great concern about the effect that the reduction of the forest can have on the climatic dynamics in this region, as well as in other brazilian locations. In such context, the present work aimed to verify if the current rate of deforestation in Rondônia, last 30 years has been contributed for ch

8. Images of the baroque memory of Ouro Preto: the baroque space as educator of imaginary from Ouro Preto / Imagens da memória barroca de Ouro Preto: o espaço barroco como educador do imaginário ouro-pretano
The present research was, theoretically and methodologically, based on an interpretative and translator analysis of the meaning of verbal and non-verbal images and symbols (semanticsymbolic hermeneutics). The purpose of it was to investigate the influence and the coimplication of the iconographic and architectural images from Ouro Pretos baroques churches on

9. 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

10. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos

12. Exploração de reordenamento de ROBDDs no mapeamento tecnológico de circuitos integrados / Exploration of ROBDD reordering on technology mapping for integrated circuits
The ROBDDs are structures that have been successfully used in CAD tools for microelectronics. These structures allow canonical representation of boolean functions when established a fixed variable ordering. In the context of an automatic logic cell generator for integrated circuits, ROBDDs may serve as a base for deriving transistor networks from which elect
