esh generation is one of the most critical aspects of engineering simulation. Too many cells may result in long solver runs, and too few may lead to inaccurate results. ANSYS Meshing technology provides a means to balance these requirements and obtain the right mesh for each simulation in the most automated way possible. ANSYS Meshing technology has been built on the strengths of stand-alone, class-leading meshing tools. The strongest aspects of these separate tools have been brought together in a single environment to produce some of the most powerful meshing available.

实现了erlang公式的计算，可通过任意两个已知变量求出另一个，有良好的GUI。(The calculation of Erlang realized the formula, which can pass any two known variables can be another, has a good GUI.)

光纤耦合器中光孤子传输的仿真研究，计算物理实习，很不错的。（转）(Fiber Coupler Simulation of optical soliton transmission, computational physics internships, very good. (Rpm))

ecent advances in electrical engineering and computer science, esp ecially in micro- electro-mechanical systems (MEMS), very-large-scale integration (VLSI) and op erating system theory, have made wireless sensor network (WSN) technologies an imp ortant and promising research area. As the circuitry b ecame smaller and cheap er, the idea of co op eratively sensing physical or environmental conditions, such as magnetic eld intensity, temp erature, light intensity, sound, vibration, pressure, motion or p ollutants with the help of a network of sensor no des has b ecome feasible.

鲸鱼优化算法（WOA）是一种用于解决优化问题的新优化技术。该算法包括三个算子，用于模拟猎捕鲸鱼的猎物，环绕猎物和泡泡网觅食行为。 压缩包具体包括该算法的发表论文、源代码、matlab工具箱。(Whale optimization algorithm (WOA) is a new optimization technology for solving optimization problems. The algorithm consists of three operators, which are used to simulate the hunting behavior of whale prey, surround the prey and bubble net. The compression package includes publishing papers, source code and Matlab toolbox of the algorithm.)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)
