1. Wi-Bio: management policy aimed at the establishment of networks for patient monitoring using IEEE 802.11
INTRODUCTION: Patient monitoring will tend to decline in the coming years due to a shortage of physical and human resources in hospitals. Therefore, several studies define alternatives to improve patient monitoring using wireless networks. In these studies, a wireless network is used to transfer data generated by medical sensors without interacting with the

2. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c

3. NSINKS: protocolo de roteamento para redes de sensores sem fio em redes com vários sorvedouros / Wireless sensor networks; Routing protocols; Sinalgo simulator
This work describes the operation of NSINKS, a protocol based ont DESRO protocol, that has the feature of working with more than one sink node and allows dynamic route management in a Wireless Sensor Network. A comparison between protocols NSINKS and DESRO was performed, using the Sinalgo simulator, that showed that the use of multiple sink nodes can increas

4. Proposta de ferramenta para desenvolvimento de simuladores interativos para treinamento. / A proposal for tools to interactive training simulation development.
Man-in-the-loop or human-in-the-loop simulations reproduce virtually real or imaginary environments to the user, being used for several purposes, such as, entertainment, training, experiment and rehabilitation. In training area, the simulators are more and more used aiming, specially for costs and risks reduction besides the total control of training conditi

5. Análise de mecanismos de replicação de dados para grades de computadores / Analysis of data replication mechanisms for grid computing
A datagrid is an distributed computing environment designed to aggregate and share storage resources that are geographically distant. Datagrids provides infrastructure and services for discovery, transfer, handling and managing large amounts of data stored in distributed repositories. The datagrids share characteristics with peer-to-peer networks, distribute

6. Uma avaliação dos mecanismos de trasmissão de tráfego para IPTV
The IPTV service offer is currently the main interest of many ISPs (Internet Service Providers). Such service comprises the continuous transmission, via an IP network, of TV programs structured into channels, like the open TV ou cable TV services. The goal is to reach the same quality of conventional TV (full screen, medium or high definition), adding the in

7. 2D laser-based probabilistic motion tracking in urban-like environments
All over the world traffic injuries and fatality rates are increasing every year. The combination of negligent and imprudent drivers, adverse road and weather conditions produces tragic results with dramatic loss of life. In this scenario, the use of mobile robotics technology onboard vehicles could reduce casualties. Obstacle motion tracking is an essential

8. Metodo de analise de trafegos VoIP sobrepostos / Method of analysis of VoIP traffic over
The behavior of VoIP traffic in network links is addressed in this work. VoIP applications have strict requirements for quality of service (QoS) that should be provided for in the network design. In this sense, the Markov Modulated Poisson Process (MMPP) is displayed as model of process of arrivals that is appropriate to characterize the behavior of superpos

9. IXnet - proposta de Internet alternativa para aplicações sensíveis a atraso. / IXnet - proposal of alternative Internet for applications sensitive to delay.
The Internet may does not meet all the demands required by applications sensitive to delay. Voice, video or even game applications demand low delay. The distance of hops between client and server, link traffic and the ramdomness of the package path, may cause delays. There is motivation and even implementation of alternative infra-structure to improve access

12. Análise de desempenho de um pavimento flexível da rodovia BR-290/RS solicitado por um simulador de tráfego móvel
Estimar com acurácia a vida útil de um pavimento é um dos maiores desafios que enfrentam os engenheiros rodoviários. Recentemente uma nova ferramenta tem sido utilizada para estimar de forma mais realista o desempenho de pavimentos; trata-se dos simuladores de tráfego. Neste contexto, esta dissertação apresenta um estudo do comportamento de um pavimen
