1. Modelagem de redes CDMA-PON baseadas em técnicas de cancelamento paralelo e códigos corretores de erros / Modeling of CDMA-PON networks using parallel interference cancellation and error correcting codes techniques
The advent of new services offered to end users, such as the so called triple play, which consists in the simultaneous traffic of voice, video, and data through the same communication infrastructure, has been pushing telecom operators towards providing adequate bandwidth as well as quality of service. This has brought the spotlight to passive optical network

3. GENERATION AND TRANSMISSION SYSTEM RELIABILITY CONSIDERING STATIC AND DYNAMIC ASPECTS / CONFIABILIDADE DE SISTEMAS DE GERAÇÃO E TRANSMISSÃO CONSIDERANDO ASPECTOS ESTÁTICOS E DINÂMICOS
Traditionally, bulk power reliability evaluations have concentrated on the analysis of system adequacy, the ability of the generating and the transmission systems to supplhy all loadas within performance requirements. This work presents a new methodology that extends the scope of reliability evaluations to include probabilistic assessment of system security,

4. Comparison of sickness absence in Belgian, German, and Dutch firms.
International comparisons of sickness absence rates are difficult to make because of different national social security arrangements or recording procedures. Therefore a cross national study of sickness absence in Belgium, West Germany, and the Netherlands focused firstly on "contextual" aspects of sickness absence such as work incapacity benefit schemes, jo
