Conflict resolution using statistical approach

Conflict can be described as a condition in which actions of one person prevent or compel some outcome at the resistance of the other. Quite often this can be seen as “two or more competing, often incompatible, responses to same event”. In this paper, a statistical approach to conflict resolution using the concept of bargaining game theory is presented. The approach gives chances of failure that are minimal...

Relationship between continuity and momentum equation in two dimensional flow

In this paper a quantitative discussion on a theory describing the relationship between the continuity and momentum equation in two dimensional flow together with the momentum equation in vectorial form:  is reported. Via expanding in cylindrical polar coordinates, the end result is proved to be Euler equation.   Key word: Continuity equation, momentum equation, cylindrical coordinates,...

Invariance of numerical range under isometric transformation

In this paper, we look at some properties of isometries and conditions for a quasi-affinity to be unitary. Among other results it is proved that if A is a partial isometry such that either 0Ñ”W(A) or 0Ñ”W(An) for some positive integer n then A is unitary.   Key words: Numerical range and unitary operator.
