“…It is known, however, these process take long time for convergence [5]. For this reason, we employ here the simplified SA in which the update descent of the level-set functions V N , is randomly reversed as follows: where f and f'are the values of the object functions before and after the update, respectively, and T n is the temperature parameter obtained by…”

Abstract-The level-set method has been shown suitable for topology optimization because it can find optimal shapes with smooth boundaries and non-porous material regions. In the level-set method, however, optimization is conducted based on the gradient method. For this reason, the solutions obtained by the level-set method tend to fall into local optima. In this work, the simulated annealing is introduced into the level-set method to solve this problem. In order to test the present method, the shape of the flux barrier in the rotor of an interior permanent magnetic motor (IPM-motor) is optimized. It is shown that the resultant properties are better than those obtained by the deterministic level-set method.

“…Lee and Lee () classified these efforts into two major categories: algorithmic optimization (of sequential SA) and parallel computing. In the category of optimizing a sequential SA, typical examples are careful perturbation (Deutsch and Wen, ) and adaptive cooling rate (Youhua and Weili, ; Azizi and Zolfaghari, ). However, Lee and Lee () pointed out that these techniques do not significantly improve the quality of the solution or execution time.…”

Recent studies have demonstrated that the performance of a simulated annealing algorithm can be improved by following multiple-search paths and parallel computation. In this paper, we use these strategies to solve a comprehensive mathematical model for a flexible flowshop lot streaming problem. In the flexible flowshop environment, a number of jobs will be processed in several consecutive production stages, and each stage may involve a certain number of parallel machines that may not be identical. Each job has to be split into several unequal sublots by following the concept of lot streaming. The sublots are to be processed in the order of the stages, and sublots of certain products may skip some stages. This complex problem also incorporates sequence-dependent setup times, the anticipatory or nonanticipatory nature of setups, release dates for machines, and machine eligibility. Numerical examples are presented to demonstrate the effectiveness of lot streaming in hybrid flowshops, the performance of the proposed simulated annealing algorithm, and the improvements achieved using parallel computation.

“…Recently, they are couple of commercial software appeared in the market due to the advance of the hardware of computer. Some of software can be used for the optimal design of conductor as introduced in [1][2][3][4][5][6][7]. During the making phase of the conductor, the presence of the bouncing behavior results in producing the electric arc that causes erosion damage on the conducting surface and greatly reduced the lifespan of the conductor.…”

In this paper, we aim at developing an interchangeable electromagnetic contactor that essentially features with high power efficiency, low electromagnetic noise, and high power resource usage. The magnetic coils of the new IC-controlled method can be excited by AC or DC voltage and the range of the operating voltage is shown to be much larger than the conventional contactor. This leads to a wider area of applications for the new contactor. According to the electric performance requirement, the pulse width modulation (PWM), which provides the suitable energy for the exciting coils under the different operating condition, is implemented in the proposed contactor. This is resulted in a stable operation between make or break phase of the contactor and greatly reduced in the electromagnetic noise and energy loss for the exciting coils. Thus, the lifespan of operation of the contactor can be greatly extended. In order to prove the validity of the proposed IC-controlled method, several experiments had been conducted and the results are shown the feasibility and reliability of the new design.
