An experimental simulation set up was designed and used to test the load-leveling function for a real pipeline system. A storage tank filled with activated carbon together with a filter constitutes the major part of the load-leveling facility. Pressure and temperature of the system, as well as the real gas output of the storage tank were recorded. It is proven that load-leveling by adsorption is technically feasible even for low pipeline pressure of natural gas supply system.展开更多

In this paper, we study the cooperative game approaches for scheduling in the wireless relay networks with two-virtual-antenna array mode. After defining the metric of relay channel capacity, we form a cooperative game for scheduling and present the interpretation of three different utilization objectives physically and mathematically. Then, a Nash Bargaining Solution (NBS) is utilized for resource allocation considering the traffic load fairness for relays. After proving the existence and uniqueness of NBS in Cooperative Game (CG-NBS), we are able to resolve the resource allocation problem in the cellular relay network by the relay selection and subcarrier assignment policy and the power allocation algorithm for both RSs and UEs. Simulation results reveal that the proposed CG-NBS scheme achieves better tradeoff between relay fairness and system throughput than the conventional Maximal Rate Optimization and Maximal Minimal Fairness methods.展开更多
