Description: 西门子仿真编程软件S7-PLCSIM V5.4，用于S7-300/400系列PLC程序的仿真-S7-PLCSIM V5.4 offers the following new features with this release:
DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI
Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node.
Increased number of blocks supported for simulation
S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.

Description: SIESTA用于分子和固体的电子结构计算和分子动力学模拟。SIESTA使用标准的Kohn-Sham自恰密度泛函方法，结合局域密度近似(LDA-LSD)或广义梯度近似(GGA)。计算使用完全非局域形式(Kleinman-Bylander)的模守恒赝势。基组是数值原子轨道的线性组合(LCAO)。它允许任意个角动量，多个zeta，极化和截断轨道。计算中把电子波函和密度投影到实空间网格中，以计算Hartree和XC势，及其矩阵元素。除了标准的Rayleigh-Ritz本征态方法以外，程序还允许使用占据轨道的局域化线性组合。使得计算时间和内存随原子数线性标度，因而可以在一般的工作站上模拟几百个原子的体系。程序用Fortran 90编写，可以动态分配内存，因此当要计算的问题尺寸发生改变时，无需重新编译。程序可以编译为串行和并行（需要MPI）模式。

能带结构-SIESTA was born in 1996 to implement, in self consistent DFT, the order-N techniques developed for tight-binding in the early 1990s. Because order-N was carefully imposed in all the code, this was very efficient, specially for large systems and moderate precisions. Later, the need for higher precisions, and the addition of many new functionalities, imposed compromises to the order-N philosophy, but efficiency kept being one of SIESTA s strongest points.

Description: FFT，即为快速傅氏变换，是离散傅氏变换的快速算法，它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得的。它对傅氏变换的理论并没有新的发现，但是对于在计算机系统或者说数字系统中应用离散傅立叶变换，可以说是进了一大步。(FFT, that is fast Fourier transform, is a fast algorithm for discrete Fourier transform. It is based on the odd, even, imaginary, real and other characteristics of discrete Fourier transform, and the algorithm of discrete Fu Liye transform is improved. It does not make new discoveries about the theory of Fourier transform, but it can be a big step for the application of discrete Fu Liye transform in computer system or digital system.
Let x (n) is a complex sequence of N, by DFT transform, either X (m) calculations are N times N-1 times complex multiplication and addition, and a complex multiplication is equivalent to four times the number of multiplication and two real addition, a complex addition is equivalent to two times the number of addition,)
