We review some of the basic mathematical results about density functional theory.

We present a network based approach to characterize C2 architectures in terms of three domain elements individuals, tasks, and resources. Characterizing the possible relations among these elements results in five relational primitives Precedence, Commitment of resources, Assignment of individuals to tasks, Networks (of relations among personnel) and Skills linking individuals to resources. We d...

The purpose of this paper is to find a set of canonical elements to use within the framework of Öpik theory of close encounters of a small body with a planet ([Öpik 1976]). Since the small body travels along a planetocentric hyperbola during the close approach and Öpik formulas are valid, without approximations, only at collision, we derive a set of canonical elements for hyperbolic collision o...

We present a network based approach to characterize organizational architectures in terms of three domain elements individuals, tasks, and resources. Characterizing the possible relations among these elements results in five relational primitives Precedence, Commitment of resources, Assignment of individuals to tasks, Networks (of relations among personnel) and Skills linking individuals to res...
