Growing bandwidth demand in the Internet requires new algorithms and architectures to provide a high degree of QoS. Further, to complicate the problem of Traffic Engineering, real time data processing requires more priority than non-real time data processing. In this paper, we present an effective solution for improving QoS of audio and video packets in MPLS networks under real time traffic conditions...
With a pair of Horizon Scanners (HS) working as attitude sensors, four horizon points are obtained during each scan. A simplified non-linear model is developed for the horizon points using an appropriate choice of frame. The modified gain extended Kalman filter is used to estimate the satellite position in the orbit reference frame based on the non-linear Horizon Scanner data. Through simulation...
A frequency domain stability criterion (sufficient condition) for a class of distributed parameter, sampled-data systems containing a memory-less, non-linear feedback element is presented. This criterion for absolute stability of the class of distributed systems considered here parallels the criterion for lumped systems obtained by Jury and Lee and it requires that the following relationship be satisfied...
