<p>O objetivo deste artigo e descrever os resultados alcançados na implantação dos planos semafóricos calculados pelo programa TRANSYT, sugeridos pelo manual do programa, quando prioridades para os ônibus nas vias principais do Rio de Janeiro são consideradas nos cálculos. Os critérios e facilidades apresentados no programa para estas prioridades tiveram como base o comportamento do trafego na Inglaterra e Escócia, onde o programa foi desenvolvido e modelado. São realizadas comparações entre a composição típica do trafego na Inglaterra e no Brasil, realizadas analises das experiências de priorizar ônibus (ou outro tipo veículo) em outras situações e países. E feita uma analise dos resultados obtidos na implantação de planos de sincronismo com prioridades para ônibus, conforme recomendado pelo manual do TRANSYT, através da comparação de várias situações relativas às simulações dos padrões e modelos de trafego, bem como tipos de planos de sincronismo simulados. Finalmente são apresentadas as soluções temporárias encontradas para o uso dos pianos de sincronismo e a indicação da necessidade de estudos específicos para a solução definitiva do problema.</p><p><strong>ABSTRACT</strong></p><p>This paper describes the results achieved when signal timing plans calculated by the TRANSYT program with bus priority are used with the values suggested by the program manual. The field trial was in the city of Rio de Janeiro. The criteria and facilities presented by the program manual for that kind of priority were based on the behavior of the traffic in the UK where the program was developed and modeled. There are comparisons between the traffic composition in the UK and 13razil, analysis of the previous experiences in bus (or other kind of vehicles) priorities, in other type of traffic situation and countries. There is an analysis of the results achieved when the signal timing plans calculated as the manual of TRANSYT suggests are implemented in the Rio de Janeiro city centre. This is made by comparisons between several scenarios regarding different patterns of traffic and traffic signal plans. Finally, it is presented temporary solutions to be used in the calculation of signal timing plans and the need for research required for more permanent achievements.</p>

SummaryThis paper reports on a computerised approach to the management of an epidemiological field trial, which aimed at determining the effects of insecticide-impregnated bed nets on the incidence of malaria in children. The development of a data system satisfying the requirements of the project and its implementation using a database management system are discussed. The advantages of this method of management in terms of rapid processing of and access to data from the study are described, together with the completion rates and error rates observed in data collection.

In this paper, a novel dual-stator permanent magnet machine (DsPmSynM) with low cost and high torque density is designed. The winding part of the DsPmSynM adopts phase-group concentrated-coil windings, and the permanent magnets are arranged by spoke-type. Firstly, the winding structure reduces the amount of copper at the end of the winding. Secondly, the electromagnetic torque ripple of DsPmSynM is suppressed by reducing the cogging torque. Furthermore, the dynamic performance of DsPmSynM is studied. Finally, the experimental results are compared with the simulation results.

SKK Migas plans to apply end-to-end security based on Web Services Security (WS-Security) for Sistem Operasi Terpadu (SOT). However, there are no prototype or simulation results that can support the plan that has already been communicated to many parties. This paper proposes an experiment that performs PRODML data transfer using WS-Security by altering the WSDL to include encryption and digital signature. The experiment utilizes SoapUI, and successfully loaded PRODML WSDL that had been altered with WSP-Policy based on X.509 to transfer a SOAP message.
