1. Modelagem de software de tempo real utilizando o profile MARTE da UML
Métodos e linguagens orientadas a objetos tem sido amplamente aplicados em atividades de modelagem e projeto de software de tempo real. Entre todas as notações orientadas a objetos a mais usada é a UML. Apesar dos seus muitos problemas conhecidos na teoria e na prática, como a fraca representação de restrições temporais e alocação de recursos, a U

2. Sistema de reconhecimento de padrÃes para identificaÃÃo de porte de veÃculos atravÃs de anÃlise de perfil magnÃtico / A Pattern recognition system for identification of vehicles by analysis of magnetic profile
Currently, transit agencies use traffic monitoring systems to reduce traffic accidents and as a fundamental tool for collecting statistical data for planning and management of road systems. These data are observed as the amount of information vehicles that travel at a certain point, the average speed and the identification of the category of vehicles. The id

3. Controle dos efeitos da mistura de quatro ondas (FWM) para melhoria no gerenciamento do QoS óptico em redes GMPLS/DWDM. / Control of the four wave mixing (FWM) effects for improvement in the optical QOS management in GMPLS /DWDM networks.
This work investigates the effects of the Four-Wave Mixing (FWM) during the lightpaths establishment in a GMPLS/DWDM (Generalized Multiprotocol Label Switching / Dense Wavelength Division Multiplexing) network. In order to minimize their impacts and thus reduce network blocking, strategies based on RSVP-TE (Resource Reservation Protocol- Traffic Engineering)

4. Nodes architecture and traffic engineering in optical networks / Arquitetura de nós e engenharia de tráfego em redes ópticas
Integrating telecommunication networks has enlarged the coverage, but has made operations more complex, mainly because of the architecture, formed by various layers. These layers deal with different protocols and transmission rates, as well as electrical and optical signals. The usual alternative of expanding the resources proportionally to the demand is imp

5. IEC-61850: interoperability and interchangeability between supervision, control and protection equipment using data communication networks / IEC-61850: interoperabilidade e intercambialidade entre equipamentos de supervisão, controle e proteção através das redes de comunicação de dados
Data communication has always been considered as a critical factor in real time operation of electric power systems. This is due to the need for fast and accurate decisions at different locations, from power generation to the user interfaces. With the digital technology, measurement, signals and commands are encrypted into data packets that travels on the su

6. Acidentalidade no transporte coletivo da cidade de São Carlos / Accident occurrence in public transportation (buses) in the city of São Carlos
This work presents the results of a study on accident occurrence in public transportation (buses) in the city of São Carlos - Brazil, using as information sources the records from police accident reports from the local police and accident reports performed by the company responsible for the public transportation (buses), both for calendar years 2005 and 200

7. Traffic signals: technical management, perception of performance, timing / Semáforos: gestão técnica, percepção do desempenho, duração dos tempos
Neste trabalho são enfocados três aspectos relacionados com a operação de semáforos: gestão técnica, percepção do desempenho e duração dos tempos. No tocante à gestão técnica, é discutida sua importância em ser realizada de maneira adequada e é investigada a situação das cidades do país em relação à questão. A conclusão é que a situ

8. 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

9. 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

10. Analise de simulação de cruzamento semaforizado
Conflicts emerge from the competition between elements participating in the circulation system, when these achieve severe degree traffic accidents occur. These accidents should be analyzed trom various points view so that its comprehension may indicate corrective measures. This work aims to identify the influence of dynamic publicity panels in the perception

11. Lipid-dependent Bidirectional Traffic of Apolipoprotein B in Polarized Enterocytes
Enterocytes are highly polarized cells that transfer nutrients across the intestinal epithelium from the apical to the basolateral pole. Apolipoprotein B (apoB) is a secretory protein that plays a key role in the transepithelial transport of dietary fatty acids as triacylglycerol. The evaluation of the control of apoB traffic by lipids is therefore of partic

12. Intracellular Traffic of Herpes Simplex Virus Glycoprotein gE: Characterization of the Sorting Signals Required for Its trans-Golgi Network Localization
Herpes simplex virus (HSV) and varicella-zoster virus (VZV) are two pathogenic human alphaherpesviruses whose intracellular assembly is thought to follow different pathways. VZV presumably acquires its envelope in the trans-Golgi network (TGN), and it has recently been shown that its major envelope glycoprotein, VZV-gE, accumulates in this compartment when e
