13. Modelagem em geometria digital aprimorada por técnicas adaptativas de segmentos de retas. / Digital geometry modelling enhancement by straight line segment adaptive techniques.
For the representation of digital straight lines, digitized straight line segments and arcs, each of the available research approaches has its advantages and suitable applications. However, taking into account the complexities of real-world scenarios, the use of these representations is not so popular in situations that require flexible models or involving s

14. Implementações sequencial e paralela de um novo algoritmo para a simulação de elementos e compostos magnéticos
The magnetic phenomena are widely used in many devices, such as electronic, data storage and telecommunications devices. The understanding of this phenomenon is therefore of great interest to support the improvement and development of new technologies. To better understand the magnetic phenomena, it is essential to study interactions at nano scale. When magn

15. Probabilistic approach for yield analysis of dynamic logic circuits
In deep-submicrometer technologies, process variability challenges the design of high yield integrated circuits. While device critical dimensions and threshold voltage shrink, leakage currents drastically increase, threatening the feasibility of reliable dynamic logic gates. Electrical level statistical characterization of this kind of gates is essential for

16. Identificando padrões comportamentais do tipo avoidance em trajetórias de objetos móveis / Identifying avoidance behavior patterns in moving objects trajectories
With the increasing availability and considerable price reduction of technologies that allow the collection of moving object data, the offering of trajectory data becomes abundant. The study of these trajectories has the objective to allow a better understanding of the data, as well as the extraction of new knowledge using computational techniques. One of th

17. Identificação e análise de sequências codificantes com atributos conflitantes em genomas procariotos / Analysis and identification of prokaryotic coding sequences with confliting atributes eng
The advent of new sequencing technologies and the development of computational tools that facilitate the analysis of genomes, generated the exponential growth of genome databases. New approaches in-silico of the comparative genomics use such data in its comparisons. Nevertheless, recent work on the genome of Escherichia coli indicate that the current state o

18. A utilização das tecnologias da informação e comunicação na prática de docentes do município de José Bonifácio - SP / The use of the technologies of the information and communication in the practical one of professors of the city of Jose Bonifácio SP
The present study is fruit of a research in which we investigated the comprehension that public school teachers have towards the use of computers in teaching. In this perspective we investigated the contexts, processes, factors, computational resources availability and the results of the educational computing introduction in schools. The data analysis and di

19. Desenvolvimento de uma ferramenta computacional experimental para navegação em sites web para cegos / Development of an experimental computational website browsing tool for the blind
Although it seems plausible to consider the importance of the Internet as an educational and/or professional tool for people with special needs, several studies support the idea that the increasing web page complexity renders access to information ever so much more difficult for the visually impaired. Based on the analysis of the resources available in some

21. ASSOCIAÇÃO DO CONTEXTO DE INTERESS DO USUÁRIO ÀS ATIVIDADES CLÍNICAS NA ARQUITETURA CLINICSPACE / Association of the Context of Users Interesting to Clinical Activity in Architecture ClinicSpace
Currently, we seek to make the systems more oriented to end-user, reducing the distance between how the user carries out its activities and modeling these in Information Systems in Health, the doctor providing adaptive and personalized forms of use, configuration and control system, based on historical usage, or a profile. To meet these requirements, the pro

22. Proposta de interconexão do padrão ISO 11783 com redes de sensores sem fio padrão ZigBee. / A proposal for interconnection between ISO 11783 standard network and ZigBee wireless sensor networks.
Precision Agriculture is one of the technological advances used to recoup the treatment of spatial and temporal variability in agricultural crops. Besides other benefits, it tries to improve the exploitation of applied inputs, improve the productivity and reduce production cost as well as lessen the impact on environment caused by excess of input. To achieve

23. EMaD - Uso de um aplicativo multimídia interativo como suporte para ensino da Semiologia Mamária / EMaD - Use of an interactive multimedia application as support for teaching Semiology Breast
The teaching techniques must be dynamic and, in fact, have made constant progress. More recently, and quite aggressive new features that implement information technology have been used in medical education. However, the lack of this feature with respect to its applicability in the teaching of gynecology is significant. The objectives of the current study wer

24. Navegando por entre trilhas digitais com novas e velhas gerações
The present research was orientated by three questions: How does the access of Internet and computer by young and old people take place? Which literacy practices are involved in this process? How do young and old people get used to virtual space? In order to answer such questions, it was important to comprehend the motivation that lead people from 14 to 24 a
