13. Um Sistema de Identificação Automática de Faces para Ambientes Virtuais de Aprendizagem
O aumento da demanda pela modalidade de Educação a Distância e o surgimento e aperfeiçoamento dos Ambientes Virtuais de Aprendizagem (AVA) apresentam-se num cenário em que se pretende minimizar distâncias e dinamizar estratégias de monitoramento dos alunos. No entanto, os AVA atuais não dispõem de recursos que identifiquem os usuários durante o des

14. Os sentidos atribuídos à promoção da alimentação saudável na escola por uma professora do ensino fundamental de Diamantina/MG / The meanings assigned to healthy feeding promotion at school by a fundamental education teacher from Diamantina/MG
If we take the health as a purpose and mean for education, the childhood as the phase when occurs the eating habits and the teacher with the preference in the action s elaboration that promote the teaching leaming in the school, this paper mainly examined the senses that a teacher makes about the viability of the healthy feeding at school. For this, we IDade

15. Algoritmos genéticos aplicados à proteção e estimação de harmônicos em sistemas elétricos de potência / Genetic algorithms applied to protection and harmonic estimation in electric power systems
The aim of electric power systems is to generate electricity and to deliver it continuously to the end-user in an acceptable standard. Therefore, different applications using genetic algorithms (GAs) to solve electric power system problems are presented in this work. Harmonic estimation, frequency relays and distance protection are the subjects investigated

17. Comparação algebrica de genomas : o caso da distancia de reversão / Algebraic genome comparison : the case of reversal distance
In the last decades we have seen a great progress in molecular biology. That lead to a large volume of data on molecules, DNA and proteins, essential for life.The current stage of research lies in the pursuit of tools to extract information with biological relevance from this data. In this context, comparison of genomes is an important tool and genome rearra

19. Poliuretanos e nanocompósitos biodegradáveis derivados de dispersões aquosas projetados para aplicações biomédicas
Waterborne polyurethane (PUDs) with potential for application as biomaterial were synthesized. Polypropyleneglycol (PPG) and/or polycaprolactonediol (PCL) were used as soft segment. The hard segment was formed by extending isophorone diisocyanate (IPDI) with hydrazine (HZ) producing poly (urethaneurea) s. PUDs were reinforced with Na+-montmorillonite (Na+-MM

20. Esqueletos euclidianos discretos em resolução aumentada / Discrete euclidean skeletons in increased resolution
The extraction of Euclidean skeletons is a subject of great importance in the domain of image processing and it has been discussed by the scientific community since more than 20 years.Today it is a consensus that Euclidean skeletons should present the following characteristics: thin, centered, homotopic and reversible, i.e., suficient for the reconstruction

21. Método de reconhecimento pessoal através da íris usando funções geoestatísticas / Method of personal recognition through iris texture using geostatistics functions
Biometrics identification methods are gaining applications each day and this has motivated a lot of research in this area. This work presents a proposal for a method to identify people through iris texture analysis using geostatistics functions and their combination. To achieve this work objective, it is considered the following phases: automatic localizatio

22. Redução de ruído em sinais de voz usando curvas especializadas de modificação dos coeficientes da transformada em co-seno. / Speech denoising by softsoft thresholding.
Many noise-reduction methods are based on the possibility of representing the clean signal as a reduced number of coefficients of a block transform, so that cancelling coefficients below a certain thresholding level will produce an enhanced reconstructed signal. It is necessary to assume that the clean signal has a sparse representation, while the noise ener

23. "Parallel implementation of the exact Euclidean distance transform" / "Implementação paralela da transformada de distância euclidiana exata"
The Euclidean distance transform is the operation that converts a binary image made of object and background pixels into another image, the Euclidean distance map, where each pixel has a value corresponding to the Euclidean distance from this pixel to the background. The Euclidean distance transform has important uses in computer vision, image analysis and r
