1. Comprobación de la uniformidad de resultados de un equipo de ensayos simultáneos de termofluencia
ABSTRACT The phenomenon of creep occurs in materials that operate under high temperatures and mechanical stresses, causing changes in their structures; such changes are evidenced by a progressive loss of mechanical strength. The characterization of this phenomenon should be performed with appropriate test machines, which are usually dependent on expensive te

2. Geração e proteção de estados comprimidos do campo e estados atômicos emaranhados em cavidades ópticas
In this work we investigated the engineering of interactions and reservoirs in the context of Cavity Quantum Electrodynamics. The investigated system consists of two identical three-level atoms trapped in two distinct traps, but inside the same optical cavity, inte- racting with the cavity mode and driven by classical .elds to manipulate the atom-.eld intera

3. Avaliação de desempenho em projetos complexos: uma abordagem multidimensional. / Complex project performance evaluation: a multidimensional approach.
This dissertation presents a study of project performance evaluation through the development of a multidimensional model that integrates the dimensions of cost, schedule and quality of the project end product. The foundation for the development of this multidimensional approach is a model that integrates the Earned Value Management (EVM) concept with Systems

4. Seleção de leveduras potencialmente produtoras de vitaminas do complexo B e estudo do processo fermentativo visando aplicação em alimentação animal / Screening of potential B-vitamin producer yeasts and the study of fermentation process for feed application
The present work had as the main the objective, the isolation and selection of potential B-vitamin producer yeast and the study of fermentative process for B-vitamin production for feed application. Among 267 isolated strains, one was selected as extracellular thiamine producer and the strain Candida sp. LEB 130 as riboflavin and biotin producer. In the stud

5. Preparação e caracterização de blendas de quitosana/poli(álcool vinílico) reticuladas quimicamente com glutaraldeído para aplicação em engenharia de tecido
In this study, novel Chitosan/PVA based films were chemically crosslinked by glutaraldehyde, under pH=(4,00 ±0,05), in order to achieve structures tailored for wound tissue engineering applications. Both precursors and developed films were characterized by FTIR, SEM and XRD in order to determine the presence of chemicals groups and nanostructural order, res

6. TÉCNICO VS. USUÁRIO: UMA ANÁLISE DO PROCESSO COMUNICACIONAL NA ENGENHARIA DE REQUISITOS DE SOFTWARE
This research analyzes a practical and a communicational problem associated to software development which takes place before the program begins to be created: the software industry professionals say that the user does not know what he wants, due to frequent change requests associated to the software requirements that originate volatile requirements. This wor

7. Avaliação de memória viso-espacial e verbal de musicistas e não musicistas
This study investigated differences in performance of musicians and non musicians on working memory tests, based on Alan Baddeleys model which refers to an integrate model of active memory that covers visual-spatial registers specialized in the visual and/or spatial codification and other registers of phonological nature specialized in the verbal codificatio

8. Nuvem de partículas aplicada à seleção de atributos
Abstract: The particle swarm optimization (PSO) algorithm is a recently developed metaheuristic technique and belongs to the category of swarm intelligence techniques. The swarm intelligence concepts are inspired by the social behavior of flocking animals such as swarms of birds, ants and fish school. PSO is a population based algorithm that exploits a popul

9. Study on factors which affect the accuracy of the filter-paper method. / Estudo sobre fatores que influenciam a acurácia do método do papel-filtro.
The purpose of this work is to verify the susceptibility of the filter-paper method to variations in three experimental parameters: roughness of porous medium (structure of porous matrix), period of exposition of the filter-paper to pore water (equilibration time) and degree of deficiency in contact between the filter-paper and the porous medium. In order to

11. Processo de desenvolvimento e testes para aplicações SIG Web / Development and testing process for GIS Web applications
Geographic Information System (GIS) is software directed to the management of geo-referenced data. GIS are systems used to store, to analyze and to manipulate geographic data, or either, data that represent objects and phenomenon where the geographic localization is an inherent characteristic. In this study, Web GIS is a system that provide different service

12. Correlation between luminescence polarization and molecular orientation in conjugated polymers / Correlação entre polarização da luminescência e orientação molecular em polímeros conjugados
The main goal of this work is the understanding of intermediated energy relaxation processes that are governed by Energy Transfer. Such processes strongly affect the optical properties of conjugated polymers, reducing the emission efficiency and the life time of OLEDs. We study specifically the polymer poly(p-phenylene vinylene), PPV, synthesized through the
