A Discrete Geometric Optimal Control Framework for Systems with Symmetries
— This paper studies the optimal motion control of mechanical systems through a discrete geometric approach. At the core of our formulation is a discrete Lagrange-d’AlembertPon...

Computational Elements of the Adaptive Controller of the Human Arm
We consider the problem of how the CNS learns to control dynamics of a mechanical system. By using a paradigm where a subject's hand interacts with a virtual mechanical envir...

The Set and Function Approach to Modeling Authorization in Distributed Systems
Abstract. We present a new model that provides clear and precise semantics for authorization. The semantics is independent from underling security mechanisms and is separate from i...
