1. Cross-cultural adaptation and face validity of the Wheelchair Skills Test Questionnaire (Version 4.3) for caregivers
Resumo Introdução: No Brasil, existe uma lacuna de ferramentas de avaliação que avaliem o uso da tecnologia assistiva e a mobilidade funcional de pessoas que usam cadeira de rodas e seus cuidadores. O Wheelchair Skills Program (WSP) é um sistema integrado que inclui instrumentos para a avaliação e o treino de usuários de cadeira de rodas, cuidadores

2. Reducing the semantic gap content-based image retrieval with similarity queries / Adequando consultas por similaridade para reduzir a descontinuidade semântica na recuperação de imagens por conteúdo
The increasing number of images captured in digital media fostered the developmet of new methods for the recovery of these images. Dissimilarity is a criteria that can be used for image retrieval, where the results are images that are similar to a given reference. The queries are based on feature vectors automatically extracted from the images and on distanc

3. Recuperação de imagens por conteúdo: uma abordagem multidimensional de modelagem de similaridade e realimentação de relevância
This work presents a multi-dimensional similarity modeling strategy and relevance feedback technique for minimizing the semantic gap intrinsic problem of CBIR systems by allowing users to customize their queries according to their requirements and preferences. We propose a composite strategy using a multi-dimensional, vectorial, spatially clustered, and rele

4. Caracterização de imagens utilizando redes neurais artificiais
Image representation in Content Based Image Retrieval systems is a fundamental task. The results obtained by these systems strongly depend on the choice of features selected to represent an image. Works in the literature show that intelligent techniques are used to minimize the semantic gap between the limited power of machine interpretation and human subjec

5. Adaptação da escala multidimensional de liderança no desporto - versão comportamentos atuais - para o contexto brasileiro de esportes coletivos
The study of leadership has been raising interest of theorists since the 1920s with the postulates of Trait Theory. In the sports context, spectators and professionals in the area ascribe significant weight to the leadership process in promoting the efficiency of teams. The measurement of this phenomenon in sports can still be considered a methodological gap

6. Empréstimos lingüísticos do português em Xerente Akwé / LINGUISTIC OPERATIONS IN THE PORTUGUESE XERENTE Akwe
Many languages, spoken by minority populations coming in contact with majority ones are losing vitality. Additionally, several other languages have become extinct, and this phenomenon is related to a cultural complexity involving a unique way to reflect on reality and to become a part of it. The reasons for this are many, and in each case, they act in differ

7. Suporte a sistemas de auxílio ao diagnóstico e de recuperação de imagens por conteúdo usando mineração de regras de associação / Supporting Computer-Aided Diagnosis and Content-Based Image Retrieval Systems through Association Rule Mining
In this work we take advantage of association rule mining to support two types of medical systems: the Content-based Image Retrieval (CBIR) and the Computer-Aided Diagnosis (CAD) systems. For content-based retrieval, association rules are employed to reduce the dimensionality of the feature vectors that represent the images and to diminish the semantic gap t

8. Metadados em multimidia : aplicações e conceitos em MPEG-7 / Multimidia metadata concepts and applications in MPEG-7
In this work, a research was made in order to present Metadata (or data about data) and specifically Multimedia Metadata applications with the MPEG-7 standard as the basis. At first, the theory concerning Metadata in general and Multimedia Metadata in particular is presented, with the purpose to prepare the reader for its uses, specially with the current exp

9. Relevance Feedback to content-based image retrieval to minimize semantic gap / "Realimentação de relevância para recuperação por conteúdo de imagens médicas visando diminuir a descontinuidade semântica"
O objetivo deste projeto de Mestrado foi o estudo, a análise e o desenvolvimento de técnicas de Realimentação de Relevância (RR) para melhorar a respostas de consultas por similaridade que empregam técnicas de recuperação de imagens por conteúdo (do inglês content-based image retrieval - CBIR). A motivação para o desenvolvimento deste projeto vei

10. Proposal of a perception color histogram as characteristic for content-based image retrieval / Proposta de um histograma perceptual de cores como característica para recuperação de imagens baseada em conteúdo
This work aims at establishing a digital image classification methodology based on perceptual colors, by generating a feature vector that allows retrieving images from a database by their content. In related works the methodologies of grouping the diverse possible colors of an image do not allow associate digitized colors and those colors perceived by human

11. Development of methods for extraction, comparison and analysis of intrinsic features of medical images, aiming at perceptual content-based retrieval / Desenvolvimento de métodos para extração, comparação e análise de características intrínsecas de imagens médicas, visando à recuperação perceptual por conteúdo
The ability of retrieving and comparing images using their inherent pictorial information is a valuable asset to answer similarity queries over medical images. Thus, having such resources added in Picture Archiving and Communication Systems (PACS) increase their applicability and importance in the context of teaching and training new radiologists on diagnosi
