Reduced-Complexity Maximum-Likelihood Detection in Downlink SDMA Systems
— The literature of up-link SDMA systems is rich, but at the time of writing there is a paucity of information on the employment of SDMA techniques in the down-link. Hence, in th...

A graph-based interface to complex hypermedia structure visualization
Complex hypermedia structures can be difficult to author and maintain, especially when the usual hierarchic representation cannot capture important relations. We propose a graph-b...

The Ants' Garden: Complex interactions between populations and the scalability of qualitative models
Ecological theories often explain the behaviour of communities in terms of the underlying interactions that take place between the species that are part of the community. This clos...
