14. DYNAMIC PILOT-SYMBOL ALLOCATION FOR CLOSED-LOOP OFDM SYSTEMS / ALOCACÃO DINÂMICA DE SÍMBOLOS-PILOTO PARA SISTEMAS OFDM DE ENLACE FECHADO
OFDM systems have gathered quite some attention from international standardization bodies for the past decade. Various works in literature aim at optimizing transmission for these systems in the open-loop scenario, i.e. when there is no feedback communication between transmitter and receiver. This work focuses on the utilization of a closed-loop for OFDM sys

15. Margem de contribuiÃÃo e a programaÃÃo linear na atividade agrÃcola: o caso de uma empresa produtora de sojas especiais
The present study has as main objective to verify as optimizing the contribution margin in the companies producing of special soy using the lineal programming. Being taken into account that in the agricultural activity, the concept of contribution margin assumes an extremely volatile behavior, in function of the existent dependence between the consumption of

16. Development and implantation of an operational setup designed for the evaluation of new tracers for oil reservoir characterization / Desenvolvimento e inplantação de um sistema operacional para a qualificação do desempenho de novos traçadores para reservatórios de petróleo
Petroleum, nowadays, is one of the most important natural resources in the world, since it is one of the main primary sources of energy and also raw material for many different products. It can be found accumulated in the subsoil, and was produced from the remaining portions of animals and vegetables, in a process that took millions of years to be concluded.

17. Um framework para automação/integração do processo de desenvolvimento de projetos de estruturas reticuladas tridimensionais
This thesis presents the arquitecture, design and implementation of a framework for the generating integration systems applied to the design process of reticular structures. These systems allow the automation of the structural design process by integrating the technologies CAD (Computer Aided Design), CAE (Computer Aided Engineering) and CAM (Computer Aided

18. In silico analysis of polymorphic microsatellites in penaeid shrimp and construction of a free-access database
We performed an in silico analysis of all microsatellites so far described for penaeid shrimp and for which the polymorphic behavior has previously been analyzed. The objective of the study was to evaluate the structural characteristics of these microsatellites and identifying patterns which allow the characterization of the nature of these sequences in the

19. Correlation between Indoor and Outdoor Human Thermal Preferences: A Study of the 55-2004 ASHRAE Standard Method / Relações entre preferências térmicas humanas no interior de edificações e as temperaturas externas: um estudo sobre o método adotado na norma AHSRAE 55-2004
Thermal comfort is specifically related to thermal behavior in response to both indoor and outdoor air temperature. Human thermal acceptability to climate changes and its effects depend on several aspects. It relies not only on local climatic conditions, but also on personal traits which can interfere seriously with thermal preferences as well as with someon

20. Avaliação da técnica de eletrodiálise para a separação de ácido lactobiônico produzido por via biotecnológica
Glicose-fructose oxidoreductase (GFOR) and glicono-d-lactonase (GL) enzymes are present in Zymomonas mobilis bacteria cells. These enzymes are capable to catalyze lactobionic acid (AL) formation (or formation of its correspondent salts) together with sorbitol from lactose and fructose. Lactobionic acid and sodium lactobionate have important applications in m

21. Hybrid neural network model of an alcoholic fermentation process / Modelagem hibrido neuronal de um processo de fermentação alcoolica
The use of ethanol as a fuel has many advantages; it has economically competed with gasoline and others fuels, substituting them in various uses. Thus, there is a great interest in optimizing all the steps of ethanol production. Only a detailed knowledge of the process dynamics can lead to optimal operation and this can be achieved through simulation using a

22. Development of polymer blends of zein and cornstarch / Desenvolvimento de blendas de zeína e amido de milho
In this work were investigated blends from zein, which is a com protein, with com starch. The objective of this work was optimizing the polymers properties and their processing characteristics and looking for a structure-properties correlation of these blends. The mixtures of pure polymers and starchlzein blends were prepared using glycerol as plasticizer in

23. A semiempirical study of the conformational behavior of cinchonidine and its interaction with methyl pyruvate
Hydrogenation of methyl pyruvate on a palladium or platinum surface in the presence of cinchona alkaloids leads to a high degree of enantiodifferentiation. In the present study, the semiempirical AM1 and PM3 methods are employed to perform a detailed analysis of the conformational behavior of cinchonidine and to study its interaction with methyl pyruvate. Ni

24. Controle avançado de um reator quimico de leito fixo : aplicação para oxidação do etanol a acetaldeido
The use of fixed bed catalytic reactors in the chemical industry, and the necessity of controlling and optimizing these reactors, have motivated the studies of dynamic models and control techniques, such as the use of Feedback-Feedforward controllers, working simultaneously. In practice, several feedforward control systems are implemented using ratio control
