An approach to handle the complex dynamics of a multi-agent system is based on distinguishing aggregation levels by structuring the system into parts or components. The behavior of...
We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...
In this article we present the University of Evora's Integrated Information System (SIIUE), which is meant to model most of the information necessary for the management and da...
A dynamic domain decomposition strategy is proposed for the effective parallel implementation of combined finite/discrete element approaches for problems involving multi-fracture a...

In this paper, we present a new model for concurrency control that supports cooperation of design tools and designers in a design environment. We capture characteristic access and...
