1. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre

2. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

3. Estratégia Híbrida para recomendação personalizada utilizando o Guia de Programação Eletrônico. / Hybrid Strategy for personalized recommendation using the Electronic Program Guide.
The wide range of digital information has become more difficult to find things that best fit the profile of those who demand something. In this context, Recommender Systems represent a solution to the above problem, since they help the user to find relevant information, operating based on information personalization, since it helps certain individuals in the

5. Novas propostas em filtragem de projeções tomográficas sob ruído Poisson
In this dissertation we present techniques for filtering of tomographic projections with Poisson noise. For the filtering of the tomogram projections we use variations of three filtering techniques: Bayesian estimation, Wiener filtering and thresholding in Wavelet domain. We used ten MAP estimators, each estimator with a diferent probability density as prior

6. Study of special modulation formats for optical communication / Estudo de formatos especiais na modulação digital para comunicações ópticas
This MSc thesis investigates optical modulation formats as an alternative to the use of the traditional intensity binary format NRZ (Non-return-to-zero). Those formats, classified as advanced, represent one of the key technologies aimed to enable the high data volume and broadband, demanded by the present telecommunication market, with cost reduction of tran

7. DESENVOLVIMENTO DE UMA FAMÍLIA DE SISTEMAS DE RECOMENDAÇÕES BASEADOS NA TECNOLOGIA DA WEB SEMÂNTICA E SEU REUSO NA RECOMENDAÇÃO DE INSTRUMENTOS JURÍDICO-TRIBUTÁRIOS / DEVELOPMENT OF A FAMILY OF SYSTEMS BASED ON RECOMMENDATIONS OF TECHNOLOGY AND ITS SEMANTIC WEB REUSE IN RECOMMENDATION OF LEGAL INSTRUMENTS-TRIBUTARIES
The huge amount of data available on the Web and its dynamic nature create a demand for information filtering applications such as recommender systems. The lack of semantic structure of data available on the Web constitutes a barrier for increasing the effectiveness of such applications family. This work discusses the analysis, design, implementation and eva

8. UM MODELO DE SISTEMA DE FILTRAGEM HÍBRIDA PARA UM AMBIENTE COLABORATIVO DE ENSINO APRENDIZAGEM / A MODEL SYSTEM FOR A HYBRID COLLABORATIVE FILTERING LEARNING ENVIRONMENT OF EDUCATION
A Web é uma excelente fonte de informação, mas um dos problemas que surgem com a grande disseminação de informações é a dificuldade de se obter informação relevante em tempo hábil e de forma precisa. Mecanismos que auxiliem o usuário na recuperação de informações tais como o Google.com, Altavista e Cadê, muitas das vezes retornam uma grande

11. SPECIFICATION OF A MULTI-AGENT SYSTEM RECOMMENDATION FOR ACTION IN CASE OF FAILURES OF SYSTEMS AUTOMATION IN CONTROL / ESPECIFICAÇÃO DE UM SISTEMA MULTIAGENTE DE RECOMENDAÇÃO DE AÇÕES EM CASO DE FALHAS DE SISTEMAS DE AUTOMAÇÃO E CONTROLE
When equipment failure occur in complex industrial plants, the automation and control system generates a great amount of alarms that can confuse the operators and lead them to take wrong decisions - the time for decision taking is very short and the amount of generated information is higher, being impossible for the operator read all of them before taking th

12. Modelo I2P : recomendação de recursos baseando-se em preferências, interesses e popularidade
The development of technologies that assist in the teach-learning process is an rgued subject in some areas of knowledge. The great diffusion of Web-based Educational Systems (WbE-S) has been shown the popularization of distance learning and its support tools. The Tidia-Ae project, support by FAPESP, aim at the development of a WbE-S that can use the concept
