a r t i c l e i n f o a b s t r a c t Keywords: Algorithms Quality of service Call admission control Performance analysis Reward optimization Wireless networks We analyze performance characteristics of a class of call admission control (CAC) algorithms designed for servicing multiple priority classes in wireless networks with the goal of quality of service (QoS) satisfaction and reward optimiza...

This paper develops a method for analyzing on-orbit satellite servicing concepts to determine if they can be used to adjust the reliability, reduce the associated costs, or improve the capabilities of spacecraft operations. Analytical methods are presented that provide an economic analysis of the feasibility of Advanced Satellite Maintenance (ASM) concepts. Beyond the strict cost savings analys...

The far-UV throughput of WFPC2 was monitored during December 1999 and January 2000 for any signs of unexpected throughput degradation following Servicing Mission 3a. No significant changes were detected.

Ghana in recent years has seen dramatic increase in vehicular growth. Vehicular transport in Ghana is growing with increased socio economic activities. With so many cars on our roads, the rate of vehicular accident has also increased with many people died or sustained serious injuries in traffic accidents. This study reports on the brake failure and its effect on road traffic accident in the Ku...

The on-orbit servicing mission assignment is very important to improve the cooperative work ratio of the on-orbit servicing spacecraft. One mission of on-orbit servicing can be fulfilled in many ways,and proper mission assignment must be guaranteed. Based on the characteristics and technical specifications of the mission planning issues, a multi-objective quantum-behaved particle swarm optimiza...
