[matlab] fulldyn.tar DL : 0: 这是一个模拟第3类模式地震波的matlab脚本。 This a collection of Matlab scripts that solve the antiplane (mode III) earthquake dynamic problem with slip-weakening friction, on a 1D fault embedded in a 2D homogeneous elastic unbounded medium. The problem is formulated as a boundary integral equation and the elastodynamic kernels are analytically derived in the spectral domain (spatial wavenumber). The method is explained e.g. by Morrysey and Geubelle (1997), and has been improved and extensively used by Nadia Lapusta, Alain Cochard, etc. -This is a Class 3 model simulation of seismic waves of matlab scripts.

[Windows Develop] Boundary DL : 0: 该程序主要针对三角形问题，通过输入三角形三条边的取值范围，自动生成边的测试值，并对测试值是否能构成三角形、是否等边三角形、是否等腰三角形、是否直角三角形进行了判定与显示。其中在测试值的生成方式上，采用了两种自动生成方式：一是健壮性测试（所谓的七点法），二是边界值分析（也即五点法）。-The program mainly for the triangle problem, by entering the three sides of the triangle range, automatically generated test edge value, and test whether the value of the triangle pose, whether the equilateral triangle, is it isosceles triangle, right triangle conducted to determine whether and显示. Which the test value is generated, using two types of automatic generation methods: First, robustness testing (the so-called seven-point method), and the other is boundary value analysis (that is, five-point method).

[Documents] 0706.0655v2 DL : 0: A cylindrical wave expansion method is developed to obtain the scattering field for an ideal two-dimensional cylindrical invisibility cloak. A near-ideal model of the invisibility cloak is set up to solve the boundary problem at the inner boundary of the cloak shell. We confirm that a cloak with the ideal material parameters is a perfect invisibility cloak by systematically studying the change of the scattering coefficients from the near-ideal case to the ideal one. However, due to the slow convergence of the zeroth order scattering coefficients, a tiny perturbation on the cloak would induce a noticeable field scattering and penetration.

Such algorithms are often more convenient than the traditional Finite Element Method (FEM), since the corresponding equations are formulated on the boundary, and, there- fore, a signiﬁ cant reduction of dimensionality takes place. Especially when the physical description of the problem leads to an unbounded domain, traditional methods like FEM become unalluring
