1. Consumption of microcomputers in Brazil: an analysis using datas from PNAD 2001 to 2007 and POF 2002-2003 / O consumo de microcomputadores no Brasil: uma análise utilizando dados das PNADs de 2001 a 2007 e da POF 2002-2003
O consumo domiciliar de microcomputadores cresceu de forma acelerado nos últimos anos. Apesar de grupos com determinadas características socioeconômicas terem um consumo maior de computadores, o consumo vem aumentando em todos os grupos. Ou seja, mesmo com diferenças grandes, o consumo de computadores não é mais uma exclusividade dos mais ricos, dos ma

2. Electric power system protection considering safety aspects of the communication network / Proteção de sistemas elétricos considerando aspectos de segurança da rede de comunicação
Modern world is more connected each day by all technological means available. This allows more people to communicate, turning the virtual communication road obligatory to the survival of small, medium and large companies, whether public or private. The great technological advance of the 20th century was the large use of the PCs (personal computer), usually c

3. Desenvolvimento de programa livre para análise de pórticos tridimensionais considerando-se a não linearidade geométrica, fissuração do concreto e ligações semi-rígidas
Structural analysis of framed structures using discrete method, wherein, splitting them into elements with simplified considerations, can bring not satisfactory results or end up using very high safety coefficient to the structure. With the growth of computing and microcomputers it is feasible the resolution of structures considering all parts, therefore thr

4. 25 anos de quimiometria no Brasil
Chemometric activities in Brazil are described according to three phases: before the existence of microcomputers in the 1970s, through the initial stages of microcomputer use in the 1980s and during the years of extensive microcomputer applications of the ´90s and into this century. Pioneering activities in both the university and industry are emphasized. A

5. Desenvolvimento de módulo computacional para a secagem estacionária de sementes / Development of a computational module for stationary seed dryng
The present work had for objective the development of a microcomputer program to determine the drying time of seeds and crops for fixed bed. It was used three lots of soybean seeds of cultivate Monsoy 7575 storage in a perforated floor drying bin with 1,86m of diameter and seed depth of 1,21m. The seeds were dried to 12% (wet basis). Before storage, the seed

6. A shot in the dark: the strategies and uncertainties of digital bridging in Brazil / Um tiro no escuro: as estratégias e incertezas da inclusão digital no Brasil
This study aimed to investigate, in the available contemporary literature, the digital bridging in general, and specifically the access possibilities of brazilian citizens to new communication technologies the existence of such possibilities classifies an individual as digitally included. The study started with those theories that explain inclusion and exclu

7. Analise das alterações nos padrões de preensão palmar em pianistas
This work describes an experimental study that aimed to quantitatively analyze the palmer gripping patterns of pianists during the execution of function tasks relating to gripping and speed of execution. Twenty-five subjects (11 pianists and 14 non-pianists) carried out 4 tasks with their right hand: Gross gripping at fast speed (T1); Gross gripping at low s

8. Utilização e compreensão do computador: Um olhar no dia-a-dia do professor / Computer use and understanding: a look at the day-to-day teacher
The presence of microcomputers in teaching, the goals and the proposals for its use have been the object of several discussions and referring, in the most different levels of intervention as the Ministry of Education and Culture (MEC) through partnerships with State and Municipal Secretary Office of Education, and also with institutions that prepare teachers

9. HIERARQUICAL NEURO-FUZZY MODELS BASED ON REINFORCEMENT LEARNING FOR INTELLIGENT AGENTS / NOVOS MODELOS NEURO-FUZZY HIERÁRQUICOS COM APRENDIZADO POR REFORÇO PARA AGENTES INTELIGENTES
This thesis investigates neuro-fuzzy hybrid models for automatic learning of actions taken by agents. The objective of these models is to provide an agent with intelligence, making it capable of acquiring and retaining knowledge and of reasoning (infer an action) by interacting with its environment. Learning in these models is performed by a non-supervised p

10. Simulação numérica bidimensional de crescimento de ligas binárias utilizando processamento paralelo / Bidimensionalnumericalsimulationofgrowthofbinaryalloysusingparallelprocessing
The directional solidification of semiconductor alloys is an usual technique for the attainment of a high quality crystalline substratum. This technique is a prototype for the study of macrocospic transport phenomena and involves the coupling of the conservation equations for mass, moment and energy. The crystalline properties of the alloy depend basically o
