13. Contribuições ao calculo de banda e de probabilidade de perda para trafego multifractal de redes / Contributions to the effective bandwidth and loss probability computing for multifractal network traffic
Multifractal modeling generalizes the existing traffic models and is believed to be appropriate to describe the characteristics of traffic flows of modern communication networks. This thesis investigates some novel approaches for bandwidth allocation, traffic prediction and byte loss probability estimation, by considering the multifractal characteristics of

14. Avaliação dos modelos de predição de propagação para telefonia móvel celular na cidade do Natal
The development of wireless telecommunication in the last years has been great. It has been taking academics to conceive new ideas and techniques. Their aims are to increase the capacity and the quality of the systems services. Cells that are smaller every time, frequencies that are every time higher and environments that get more and more complex, all those

15. Analysis of noise in urban bus station: development of models of prediction / Análise de ruído em terminais de transporte coletivo urbano: desenvolvimento de modelos de previsão
Diante da crescente demanda por transporte coletivo nas médias e grandes cidades é cada vez mais comum a implantação de terminais que visam interligar as linhas e/ou modos do sistema de transporte, tornando-o mais eficiente. O tráfego constante de veículos pesados (ônibus) em seus interiores faz com que esses ambientes atinjam altos níveis de ruído.

16. A multifractal traffic model with application in network traffic prediction proposal and evaluation / Um modelo multifractal aplicado a predição de trafego de redes-proposta e avaliação
Dynamic traffic control mechanisms can improve network resource utilization. The fractal traffic correlation structure can be exploited for designing dynamic network control mechanisms. Playing the most important role in the dynamic control mechanisms, traffic predictors can be accomplished from statistic traffic models able to describe the network traffic b

17. Influencia da forma urbana em ambiente sonoro : um estudo no bairro Jardins em Aracaju (SE)
Environmental noise pollution resulting from the combination of various noise sources, such as, alarms, sirens, commercial activities and services, religious temples, industries, civil engineering works and the traffic of automobile vehicles, have increased the level of urban noise and contributed to the appearance of sound environments that are more and mor

18. Prediction and classification of soil compaction due to agricultural machine traffic using fuzzy modeling. / Estimativa e classificação da compactação do solo pelo tráfego de máquinas agrícolas através da modelagem nebulosa.
A mecanização agrícola é um dos principais componentes tecnológicos responsáveis pelo avanço na produção agrícola brasileira, nos últimos anos, contudo, sua utilização aumenta o risco de impactos ambientais negativos relacionados à degradação dos solos, notadamente à compactação excessiva pelo tráfego de máquinas. A adoção recente de s

19. TRAFFIC CONTROL THROUGH FUZZY LOGIC AND NEURAL NETWORKS / CONTROLE DE SEMÁFOROS POR LÓGICA FUZZY E REDES NEURAIS
This work presents the use of fuzzy logic and neural networks in the development of a traffic signal controller - FUNNCON. The work consists of four main sections: study of traffic engineering fundamentals; definition of a methodology for evaluation of traffic controls; definition of the proposed controller model; and implementation on a case study using rea

20. ALOCAÇÃO ANTECIPADA DE BANDA PASSANTE PARA FONTES DE VÍDEO COM QUALIDADE DE SERVIÇO GARANTIDA / BANDIWIDTH ALLOCATION FOR VIDEO SOUERCES WITH QUALITY OF SERVICE GUARANTEE
In this work the Anticipated Traffic Allocation Protocol (ATAP) for Video sources in ATM (Asynchronous Transfer Mode) networks is analyzed. The ATAP is an anticipated bandwidth allocation proposal for periodic variable bit rate (VBR) sources, which has the ability to handle application with QoS requirements equivalent to CBR (Costant Bit Rate) class services

21. The role of driver demerit points and age in the prediction of motor vehicle collisions.
The records of drivers, selected from the file of licensed drivers in Ontario, were reviewed to study the relationship between demerit points, other driver characteristics, and the frequency or risk of future collisions and traffic convictions. A stratified sample of 500-600 drivers from each of five levels of demerit points was selected. Low-point drivers d

22. TrwD, the Hexameric Traffic ATPase Encoded by Plasmid R388, Induces Membrane Destabilization and Hemifusion of Lipid Vesicles
TrwD, a hexameric ATP hydrolase encoded by plasmid R388, is a member of the PulE/VirB11 protein superfamily of traffic ATPases. It is essential for plasmid conjugation, particularly for expression of the conjugative W pilus. In the present study, we analyzed the effects that TrwD produced on unilamellar vesicles consisting of cardiolipin and phosphatidylchol

23. The Escherichia coli dnaN159 Mutant Displays Altered DNA Polymerase Usage and Chronic SOS Induction
The Escherichia coli β sliding clamp, which is encoded by the dnaN gene, is reported to interact with a variety of proteins involved in different aspects of DNA metabolism. Recent findings indicate that many of these partner proteins interact with a common surface on the β clamp, suggesting that competition between these partners for binding to the clamp m

24. Self-Assembly of the Agrobacterium tumefaciens VirB11 Traffic ATPase
The Agrobacterium tumefaciens VirB11 ATPase is a component of a type IV transporter dedicated to T-DNA delivery to plant cells. In this study, we tested a prediction from genetic findings that VirB11 self-associates in vivo. A chimeric protein composed of VirB11 fused to the DNA binding domain of λ cI repressor protein formed dimers, as shown by immunity of
