Cardinality matrix problems are the underlying structure of several real world problems such as rostering, sports scheduling , and timetabling. These are hard computational problem...
We introduce the concept of concurrent signatures. These allow two entities to produce two signatures in such a way that, from the point of view of any third party, both signatures...
Abstract. Due to the complexity and uncertainties, the engineering process requires dynamic collaborations among the heterogeneous systems and human interactions. In this paper, we...

In P2P systems, users often have many choices of peers from whom to download their data. Each user cares primarily about its own response time, which depends on how many other use...
Many real-world graphs have been shown to be scale-free— vertex degrees follow power law distributions, vertices tend to cluster, and the average length of all shortest paths is...
