13. Espectroscopia por ressonância magnética de prótons em epilepsia mioclônica juvenil sugere o comprometimento de uma rede neuronal específica
OBJECTIVES: The neuroanatomical basis and the neurochemical abnormalities that underlay juvenile myoclonic epilepsy (JME) are not fully defined. While the thalamus plays a central role in synchronization of widespread regions of the cerebral cortex during a seizure, emerging evidence suggests that all cortical neurons may not be homogeneously involved. The p

14. MÃtodos de sincronizaÃÃo de conversores em sistemas de geraÃÃo distribuÃda / Converter synchronization methods for distributed generators systems
The use of frequency converters DC/AC to integrate renewable energy as distributed generation is becoming more common. In such applications, the synchronization with the voltage vector is fundamental to control the converters, particularly considering the new requirements on Low Voltage Ride Through demanded from the distributed generation. This work propose

15. Aplicação do controle baseado em passividade em conversores estáticos operando como préreguladores de fator de potência
This work studies a passivity based control approach applied to a switch-mode converters, specially the non isolated step-down (buck) converter operating in continuous conduction mode. Passivity is funded in energy concepts and consists in adjusting the system stored energy in order to achieve stability. Two different techniques are described: First, the dir

16. Method for eliciting the quality of service parameters for interactive and mobile services. / Método para identificação de parâmetros de qualidade de serviços aplicados a serviços móveis e interativos.
In these days the final users wish to obtain, to furnish and to interact using interactive services with multimedia content anywhere, anytime and with any kind of user device. One of the biggest challenges is to assure the End-to End Quality of Service (E2E QoS) in the delivering of the interactive and multimedia services for moving users. In general, this k

17. Uso de controle geométrico em sincronização aplicado à estimação de parâmetro de sistemas dinâmicos / Use of geometric control in synchronization applied to parameter estimation of dynamical systems
This work proposes a parameter estimation method for nonlinear dynamical systems based on nonlinear control techniques and synchronization. The central idea of the method is to synchronize the model with the system, and, in parallel, to estimate the systems parameters. Synchronization is achieved by the use of nonlinear geometric control techniques, and the

19. Avaliação da eficiência de métodos de coordenação semafórica em vias arteriais / Performance analysis of traffic signal synchronization methods for arterial streets
Traffic signal synchronization strategies are useful to improve traffic flow mobility and level of service of arterial streets. Therefore, technicians in charge of management of the traffic system operation should take advantage of the benefits of these tools, as always as possible, in order to define the most adequate traffic signal offsets. However, interv

20. Alinhamento de seqüências biológicas em arquiteturas com memória distribuída
The use of cluster of computers for solving problems that require a great quantity of computational resources is becoming an interesting alternative. Clusters are economically feasible and of easy maintenance, offering a computational power equivalent to that of supercomputers. However developing applications for this kind of architecture is complex because

21. Local DNA sequence alignment in a cluster of workstations: algorithms and tools
Distributed Shared Memory systems allow the use of the shared memory programming paradigm in distributed architectures where no physically shared memory exist. Scope consistent software DSMs provide a relaxed memory model that reduces the coherence overhead by ensuring consistency only at synchronization operations, on a per-lock basis. Much of the work in D

22. Uma estratÃgia para a composiÃÃo formal de frameworks
Framework based development has been presented as the next step towards better software reuse. The increasing complexity of computer systems requires the level of reuse that framework composition can achieve. In this scenario, new framework documentation and specification techniques that can eliminate behavior ambiguities and imprecision are overdue. The str

23. The associated Planting among banana (Musa acuminata cv. Big it Sleeps) and "feijão-de-porco" (Canavalia ensiformis (L.) D. C.): an agronomic evaluation of the effects of the competition for water, nitrogen and luminous energy / O plantio associado entre banana (Musa acuminata cv. Grande Nane) e feijão-de-porco (Canavalia ensiformis (L.) D. C.): uma avaliação agronômica dos efeitos da competição por água, nitrogênio e energia luminosa
In tropical regions, intensive banana (Musa accuminata) monocropping has severe agronomic and environmental impacts, and the sustainability of this production is actually highly compromised. Yield reductions are principally due to the decrease of soil fertility and root systems damages by sod fungus and nematodes. Several alternatives actually aim to improve

24. Protein and starch sources varying in rumen degradability on nutrient digestibilities, ruminal and blood parameters of nelore steers. / Digestibilidade de nutrientes e parâmetros ruminais e sanguíneos de novilhos nelore alimentados com fontes protéicas e energéticas com diferentes degradabilidades ruminais.
Four Nelore steers, cannulated in the duodenum and in the rumen, averaging 300 kg of live weight, were used in a 4x4 Latin Square design, to test the improvement of ruminal synchronization of starch and protein degradation. Two methods of corn processing (fine grinding (1,5mm) vs steam flaking (300g/l)) and 2 protein sources (soybean meal vs urea) were compa
