The S region of the H-2 complex controls the serum levels of two proteins, Ss and Sip, which are closely related antigenically (1-4). Several observations suggest that the Ss protein may be part of the complement system and homologous to C4. F(ab')2 fragments of antibody to Ss inhibit the hemolytic activity of mouse serum (5) and Ss antigenic determinants are incorporated into immune complexes ...

Nuno Ferreira - Extended Abstract

Software development in highly variable domains constrained by tight regulations and with many business concepts involved results in hard to deliver and maintain applications, due to the complexity of dealing with the large number of concepts provided by the different parties and system involved in the process. One way to tackle these problems is thru combining software product lines and model-...

In this paper we present a simple model for satellite constellations with polar orbits and inter-satellite links. This model is used to propose and study two algorithms for routing and re-routing communications, which aim at improving the quality of service for long communications. In order to study these algorithms, we have developed a satellite constellation simulator. Some of its results

IN PRESS Paulo Ferreira CURRICULUM

This special issue of Computers & Graphics is devoted to Pervasive Computing and Ambient Intelligence and its relation to mobility, ubiquity and wearable computing. This is a rather exciting area because it entails an ambitious vision of the future in which computers adapt to people, instead of being the other way round, as it happens today. We will be surrounded by intelligent devices embedded...
