Process of spectrum allocation is equivalent of rental market in cognitive radio, in order to rent free spectrum of authorized users to cognitive users. the lessors of Spectrum( between authorized users )use the methods of competition between authorized users, Lessees of Spectrum( between cognitive users ) also used the methods of game, the spectrum allocation between authorized user and cognitive...
In this paper a mixed control allocation with explicit control law is presented based on optimal weight determined by genetic particle swarm optimization algorithm for over-actuated flight system. The design combines tracking error of virtual control with effectors energy, and the attainable subset formulation scheme is concluded according to the uniform control law expression. By introducing crossover...
Thread pool is widely used in the implementation of middleware such as web application server and transaction monitor. This paper presents an adaptive threads-pool model fuzzing management framework based on multiple evaluation criteria which can adjust the size of threads pool according to current computing resources state and incoming requests number. Applying this methodology to the .NET thread...
This paper firstly introduced the basic idea of task requirement driven sensor management (TRDSM) and analyzed the task requirement of target tracking. Then, a new approach is proposed to deal with the multi-sensor management problem. The new method uses centralized management model to control sensors and the method comprehensively considers target priority and sensor usage cost. Then, sensors resource...
Global value chain (GVC) has broadened the international division participation of a state or an area with economic policies. The actors in global value chain obtained different profit. The paper from economic rent view stressed the significance of inter-corporation rents and analyzed profit allocation in the global value chain. We find that the profits depend on the market structure of product stages...
