14. As novas configurações do Estado sob as influências do terceiro setor na contemporaneidade : um estudo sobre o papel do voluntariado no âmbito empresarial e escolar
This research has the purpose to problematize the devices wich are direct related with the new configurations of the relations between the public and private spheres, through the process of restructure the state. For this, will be problematize the expansion of the "third sector" and the impacts of their actions, that are spread in our communities through the

15. Modeling and system architecture for eletronic learning monitoring and tracking. / Modelagem e arquitetura de sistemas para monitoração e acompanhamento da aprendizagem eletrônica.
This thesis proposes concepts, processes and a system architecture for Monitoring and Tracking E-Learning. The architecture is defined by a conceptual model, the interaction with external services and representation XML of the concepts and the services. It does not depend on any specific pedagogical boarding. The Monitoring Point is inserted in some places o

16. Uma abordagem livre de modelo para rastreamento de objetos em seqüências de imagens. / A model-free approach for object tracking in sequences of images.
This work proposes an approach to track objects observed in sequences of images. The main objective is the development of an efficient methodology, capable of performing the tracking of one or more heterogeneous targets by using a small amount of a priori information about them. To accomplish this objective we propose a description of the targets free of an

17. Kinematical analysis of handball players trajectories obtained by automatic tracking / Analise cinematica das trajetorias de jogadores de handebol obtidas por rastreamento automatico
The collective sports have become object of scientific investigation in many knowledge areas. A lot of these studies need the development of methodology to quantify the analysis variables. The kinematical analysis of players by videogrammetry gives data about player s position in function of time and gives advantages, like the possibility to analyze lots of

18. Rastreamento de objetos baseado em reconhecimento estrutural de padrões / Object tracking based on structural pattern recognition
Diversos problemas práticos envolvendo sistemas de visão computacional, tais como vigilância automatizada, pesquisas de conteúdo específico em bancos de dados multimídias ou edição de vídeo, requerem a localização e o reconhecimento de objetos dentro de seqüências de imagens ou vídeos digitais. Mais formalmente, denomina-se rastreamento o proce

19. Detecção de movimento de objetos em tempo real utilizando dispositivos de lógica programável complexa / Real time detection of moving objects using programmable logic devices
A system that performs movement detection in a sequence of images looks for signs that confirm the occurrence of the movement in the controlled environment. Once the movement of the object is detected it is possible to perform the tracking of the object. Real time object detection and tracking techniques are of great interests to researchers and industries b

20. Um middleware reconfigurÃvel para redes de sensores sem fio
The WSN attractivity for environment conditions monitoring and to be the bridge between the physical and virtual world has been increasing due to the advances in the micro-electronics, which enabled the production of several sensor types like illumination, humidity, temperature, smoke, radiation, acoustic, seismic, etc. in a chip that processes the signal an

21. Utilizando visão computacional para simular comportamentos de multidão de humanos virtuais
This study presents a model to extract information from the real world using computer vision techniques. In particular, we use tracking algorithms to extract the trajectories of filmed people, aiming to simulate and validate the behavior of virtual human crowds.A great challenge when trying to reproduce in a realistic manner (by means of simulation) the beha

22. Pontos de caso de uso técnicos (TUCP) : uma extensão da UCP
The software engineering argues the implantation of activities of size estimates, effort, period and cost, as forms of improving the software projects planning and tracking. In spite of there being several techniques of estimates, the use of the same ones in software companies is not still such a common practice. The technique UCP (Use Case Points), for inst

23. Um ambiente distribuido para rastreamentos de objetos em tempo real
This thesis deals with the problem of tracking objects from multiple static cameras. Each camera covers a specific area where the events take place, and the union of the images of the cameras cover the whole tracking area. The thesis presents a system that divides the tracking in two modules. The first module detects all the objects present in the tracking a

24. Time-resolved analysis and visualization of dynamic processes in living cells
Recent development of in vivo microscopy techniques, including green fluorescent proteins, has allowed the visualization of a wide range of dynamic processes in living cells. For quantitative and visual interpretation of such processes, new concepts for time-resolved image analysis and continuous time–space visualization are required. Here, we describe a v
