In this paper, to increase the accuracy and the rate of convergence of the algorithm, by employing orthogonal experiment and mutation operation to the traditional Quantum-behaved Particle Swarm Optimization (QPSO), an improved QPSO (IQPSO) has been presented. The optimization criterion, the ITAE (Integral of Time and Absolute Error) tested that the efficiency of IQPSO is superior to the traditional...
Assistance based communication plays a significant role in data transmission in wireless mesh networks, as it not only improves the transmission efficiency of the network, but also helps to coordinate the transmission between different nodes with different conditions to achieve the global synchronization. To realize the assist based data transmission over the whole mesh network, we set up an optimized...
Having as symmetric a radiation drive as possible is very important for uniformly imploding the centrally located capsule in laser-driven Inertial Confinement Fusion (ICF). Usually, intensive computation is required to analyze and optimize the radiation symmetry in ICF. In this paper, a novel compressive analysis approach is presented to efficiently evaluate and optimize the radiation symmetry. The...
Nowadays, the exploding number of functionally similar Web services has led to a new challenge of selecting the most relevant services using quality of service (QoS) aspects. Traditionally, the relevance of a service is determined by computing an overall score that aggregates individual QoS values. Users are required to assign weights to QoS attributes. This is a rather demanding task and an imprecise...
