1. Prediction of 3D ground reaction forces during gait based on accelerometer data
Abstract Introduction The aim of this study was to predict 3D ground reaction force signals based on accelerometer data during gait, using a feed-forward neural network (MLP). Methods Seventeen healthy subjects were instructed to walk at a self-selected speed with a 3D accelerometer attached to the distal and anterior part of the shank. A force plate was

2. Uma variação do protocolo DCCP para redes de alta velocidade / A DCCP variation for high speed networks
Os protocolos da camada de transporte na Internet, TCP e UDP, não oferecem serviços para transmissão eficiente de fluxos multimídia, porém, este último é adotado com maior freqüência por essas aplicações. Uma proposta de um novo protocolo da camada de transporte, chamado DCCP, foi elaborada para atender a demanda das aplicações multimídia e sub

3. Heuristic solutions related to challenges of optical burst switching paradigm
Several optical network switching paradigms have been under intensive research to support rapidly increasing bandwidth requirements. Of all these paradigms, optical burst switching (OBS) is a promising switching paradigm for the next-generation Internet infrastructure. Despite the significant contributions of OBS to high speed networks such as dynamic connec

4. Análise de redes ópticas de alta velocidade baseadas na tecnologia CDMA e códigos bidimensionais (comprimento de onda/tempo) / Analysis of high-speed optical wavelength/time CDMA networks
Esta dissertação apresenta uma análise realista de redes OCDMA (acesso múltiplo por divisão de código) baseadas em dois formatos de modulação distintos, qual sejam, OOK (chaveamento on-off) e PPM (modulação por posição de pulso). O desempenho desses formatos de modulação sob dois esquemas de codificação bidimensionais (2-D), isto é, pulsos �

5. An approach to inter-domain resource reservation for QoS management in next generation networks / Uma abordagem para reserva de recursos no gerenciamento de QoS entre dominios em redes de proxima geração
The technological evolution that happened on the last decades fostered the steep growth of the Internet, the creation of new Internet capable devices, like sensors and PDAs, and the creation of a multitude of online applications. This new scenario brought challenges very different from those initially considered on the creation of the Internet, so emerged th

6. Estudo da dinâmica de epidemias em redes aleatórias
We present a deterministic model SEIR (susceptible, exposed, infected, recovered) to the dynamics of epidemics of influenza, we calculate its equilibrium points and the basic reproductive number (R0). The results of simulations of the dynamics of contagion are shown, in a population subdivided in demes using three types of complex networks which have the cha

7. Análise mercadológica para a implementação da tecnologia FTTH: uma aplicação do método SWOT / Marketing analysis for FTTH technology implementation: an application of SWOT method
The fiber optics is a transmission system that has been used to enable products that need high bandwidth, such as the telephone system, videoconferencing, local area networks (LANs), downloads of large files etc. In Brazil, we found an increased number of fiber optic networks. This ratify its advantages in relation to metal wire cable (immunity to electromag

8. Analysis of TCP protocols for high speed networks / Analise de protocolos TCP para redes de alta velocidade
The importance of the Reno TCP protocol started operating in January 01 st, 1983. Since this milestone, there were expressive advances on data transmission technologies, such as those of optical fibers and satellite channels which allow high transmission rates on long distances. Reno TCP remains the Internet standard protocol. However, its operation presents

9. Gerenciamento ativo de filas para o protocolo "High Speed Transmission Control Protocol" em redes com produto banda-atraso elevado / Active queue management High Speed Transmission Control Protocol in high bandwidth-delay networks
The efficient utilization of bandwidth in high speed and large delay networks, called high bandwidth-delay product networks (BDP), has become a major challenge. This is due to adjustments of the Transmission Control Protocol (TCP). The High Speed TCP HSTCP): a TCP variant to high BDP networks, employs more aggressive adjustments, allowing scalable bandwidth

10. Performance evaluation of content-based image retrieval on networks / Avaliação do desempenho de recuperação de imagens médicas baseada em conteúdo em redes de computadores
The field of information retrieval based on visual contents, has increased in importance due to its great deal of available material, including digital images and videos, which has been shared and disseminated mainly via internet. Thus, new patterns of consumption, handling, and exploration of digital materials have been developed using proper organization a

12. Indústria bancária brasileira : construindo cenários prospectivos e identificando as estratégias e os recursos competitivos de utilização mais provável
Over the last two decades, Brazil has witnessed a process of significant changes in its economy, characterized by deregulation movements, economic openness and entrance into the international scenario, which generated greater market complexity, greater transformation speed in its structures and, also, less predictability towards the future (SHWARTZ, 2006). I
