Research in collaboration has yielded a large number of tools and environments. A number of classification frameworks exist that organize these contributions, but none of them are comprehensive enough; they focus either on a particular aspect of collaboration or on the specific mechanism that the tools follow. We have developed a new framework that is based on the collaboration needs of a devel...

In this paper, we describe a non-invasive approach for validation of class invariants in C++ applications. Our approach is fully automated so that the user need only supply the class invariants for each class hierarchy to be checked and our validator constructs an InvariantVisitor, a variation of the Visitor Pattern, and an InvariantFacilitator. Instantiations of the InvariantVisitor and Invari...

This paper describes research conducted in order to introduce traditionally static spatial concepts, like generalisation, into a temporal schema and study their aspects concerning Change over time. Temporal generalisation regards the representation of each object and its Changes over different time scales. It is within the logic of the proposed model to contain strict formalizations of the obje...

The two notions discussed in the paper are Life Satisfaction, under Subjective Well-Being (SWB) field; and Maslow hierarchy of human needs. Issue: Human needs satisfaction is not an all-or-nothing phenomenon. Individuals required to completely satisfy one need order for next appear hierarchy. Purpose: This aims investigate level life relation difficulty convenience achieving Approach: Mann Whit...
