The control of nonholonomic and underactuated systems with symmetry is illustrated by the problem of controlling a bicycle. We derive a controller which, using steering and rear-w...
We investigate a state feedback Linear Quadratic Regulation problem with a constraint on the number of actuation signals that can be updated simultaneously. Such a constraint aris...
In this paper, we consider the problem of incorporating privacy protection in a biometric access control system. An Anonymous Biometric Access Control (ABAC) system is proposed to...
In a real-time database system, it is difficult to meet all timing constraints due to the consistency requirements of the underlying database. However, when the transactions in t...
This paper describes a system that performs hierarchical error repair for illformed sentences, with heterarchical control of chart items produced at the lexical, syntactic, and se...
