This paper studied the optimization of the shunt release electromagnet based on Ansoft maxwell finite element simulation. The minimum size as the optimization target by taking into account the electromagnet force and temperature rise limit. In this study the electromagnetic force is calculated using finite element simulation, demand of temperature rise limit is satisfied by limiting the maximum current...
In low-voltage apparatus, characteristics of the arc motion can be influenced by magnetic field, gas flowing, electrical field etc. Many studies have been done to investigate effect of magnetic and gas flow force to the arc movement. In this paper, a 2D MHD model is established to analyze arc separating process across the splitter plates. High resistance electrode is introduced to simulate voltage...
The proposal of this paper is to establish a numerical model to simulate mechanical, thermal, electric and magnetic behavior of the electrical contact. The coupling model of mechanical, thermal, electrical and magnetic field is uncoupled into two sub models: structural thermoelectric and magnetic models. By using ANSYS software the direct-coupling of structural and thermoelectric fields is solved...
The paper proposes a quantum particle swarm optimization (QPSO) based multiuser detection for the antenna-diversity-aided multicarrier code-division multiple-access (MC-CDMA) systems. Due to the spatial receive-diversity, the received signals at the different antennas are faded independently, resulting in an independent log-likelihood function (LLF) for each receive-antenna. To resolve the multi-objective...
This paper proposes a discrete quantum-behaved particle swarm optimization (DQPSO) and applies it to realize the multiuser detection for multicarrier code-division multiple-access (MC-CDMA) systems. The continuous quantum-behaved particle swarm optimization (QPSO) is extended to the discrete scenario. To prevent the premature convergence of DQPSO, the equilibrium position is generated by balancing...
This paper proposes a multi-motor synchronous control method based on fuzzy support vector machine (FSVM). The evaluation parameters of synchronization-error, tracking-error and dynamic-error are determined under complex interference situations. The experimental results of six-motor synchronous control show that the method can not only reduce the tracking-error and synchronization-error when compared...
This paper proposes a novel optimization algorithm — adaptive chaotic particle swarm optimization (ACPSO). The short-term chaotic search is applied to the best particle in the iteration and an adaptive mechanism is used to control the scale of chaotic turbulence, which can avoid trapping in local optima and improve the searching performance of chaotic particle swarm optimization (CPSO). Simulation...
An ant colony optimization (ACO) based multiuser detection (MUD) for the receive-diversity aided space-time block coding (STBC) systems is proposed. The ants are allowed to deposit pheromone based on the concept of Pareto optimality, using the information from the individual antennas independently. Simulations show that detector employing the Pareto optimality has enhanced bit-error-rate (BER) performance...

Silicon secondary crosslinked interpenetrating polymer networks (IPNs) of poly(methyl acrylate-co-hydroxylethyl acrylate) (PMA-HEA) and SiO 2 were prepared and characterized. The effects of composition, water content and substrate plate on the phase morphology of the IPNs of PMA-HEA/SiO 2 were studied by SEM, and the T g measured by d.s.c. The broadening of the transition...
