First, the convergence conditions of Gauss - Seidel method and Jacobi method are shown. And then the iterative times of the two methods are discussed and the formula of estimate iterative times is obtained. Finally, a numerical example is calculated by the two methods and the results show the actual iterative times and the estimate iterative times are basically equal.
A numerical model for semiconductor laser diodes that predicts laser performance in high speed optical interconnect applications has been developed. The model is based on the temporal numerical simulation of the rate equation for semiconductor laser diodes. The popular math package MATLAB has been used to simulate the dynamic behavior of carrier and photon density. The term turn on delay time is defined...
This paper studies different kinds of methods on irregular object simulation, the methods applied mainly include the particle system method, the mathematic and physics-based method and the texture based method. Combining with the characteristic of each model, advantages and disadvantages of above methods, scope and effectiveness of the features were compared and the development of irregular objects'...
In the motion control of the sensorless permanent magnet synchronous motor system, the accurate detection of the rotor position at low or zero speed can improve control precision and enhance reliability. In this paper, a sliding mode observer is proposed based on the high frequency signal injection to estimate rotor position of the sensorless permanent magnet synchronous motor. Simulation results...
This paper investigates the variation of depletion region width in the p and n layers and the total depletion region width of GaN-based pin ultraviolet (UV) detector with applied voltage. The variation of barrier capacitance with applied voltage is presented. The carrier number in the depletion region of detector generated by the light irradiation has relationships with width of the depletion region...
