Issues of stability of the Tethered Satellite System (TSS) during station-keeping, deployment and retrieval are considered. The basic nonlinear equations of motion of the TSS are derived using the system Lagrangian. Using ...

The objective of this paper is twofold. First, an optimality test is presented to show that the optimality conditions for a two- level design optimization problem before and after its decomposition are the same. Second, ...

The walking machine presented in this paper consists of six walking legs arranged in a triangular configuration. Each leg may have two modes of operation: an elliptical mode for walking on a flat plane and a circular mode ...

We characterize multiple-access interference for cellular mobile networks, in which users are assumed to be Poisson-distributed in the plane and to employ frequencyhopped spreadspectrum signaling with a transmitter-oriented ...

A significant number of Model Predictive Control algorithms solve on-line an appropriate optimization problem and do so at every sampling point. The major attraction of such algorithms, like the Quadratic Dynamic Matrix ...

The goal of this paper is to study how a surface force profile may be estimated from the information on strain or stress distribution detected by tactile sensors. This problem is referred to as the inverse problem since ...

Let L_N be the number of digital line segments of length N that correspond to lines of the form y = ax + BETA, 0 <= a, BETA <=1. In a previous paper [4], a closed form expression for the quantity L_N was obtained. We prove ...

The traditional, fragmented approach to increasing manufacturing efficiency has resulted in "islands of automation" in our factories. Computer Integrated Manufacturing (CIM) is the goal of tying together these islands into ...

In this paper we address the problem of combatting combined interference in spreadspectrum communication links. We consider frequency-hopped spread-spectrum systems with M-ary FSK modulation and noncoherent demodulation ...

In [5], the authors showed that threshold policies solve an optimal flow control problem for discrete-time M|M|1 queues, where the decision-maker seeks to maximize the system throughput subject to a bound on the long-run ...
