In any multidimensional visualization, some information has to be compromised when projecting multidimensional data to twoor three-dimensional space. We introduce the concepts of dimensional and object coherence and correlation to analyze and classify multidimensional visualization techniques. These concepts are used as principles for our design of Hifocon, a new multidimensional data visualiza...

This paper deals with an annotation-based decisional system. The decisional system we present is based on multidimensional databases, which are composed of facts, dimensions, measures, hierarchies and parameters. The expertise of decision-makers is modelled, shared and stored through annotations. These annotations allow decision-makers to make an active reading and to collaborate with other dec...

A fundamental question arising in queueing system analysis is whether a system is stable or unstable. For systems modelled by infinite Markov chain, we may study ergodicity and nonergodicity of the chains. Foster [6] showed that sufficient conditions for ergodicity are linked with the average drift, however. complications arise when multidimensional Markov chains are analysed. We shall present ...
