TOYFDTD1 is a stripped-down minimalist, 3D FDTD code demonstrating the basic tasks in implementing a simple 3D FDTD simulation. An idealized rectangular waveguide is modeled by treating the interior of the mesh as free space and enforcing PEC conditions on the faces of the mesh. A simplified plane wave source is inserted at one end. First released 12 April 1999. Version 1.03 released 2 December 1999.

* A ncurses user interface. * Network statistics to view the amount of packets and data in many different protocols, interfaces and hosts. * View what active TCP connections are on the network. * View UDP packets. * View and log ICMP packets. * View and log the 48bit arp protocol. And also view what make of network card is in each machine * Multithreaded so that the user interface does not interfere with any of the packet captureing methods. * View and log the following user space protocols FTP, POP3, HTTP

遺傳算法(Genetic Algorithm, GA)是近幾年發展起來的一種嶄新的全局優化算法，它借 用了生物遺傳學的觀點，通過自然選擇、遺傳、變異等作用機制，實現各個個體的適應性 的提高。這一點體現了自然界中"物競天擇、適者生存"進化過程。1962年Holland教授首次 提出了GA算法的思想，從而吸引了大批的研究者，迅速推廣到優化、搜索、機器學習等方 面，并奠定了堅實的理論基礎。 用遺傳算法解決問題時，首先要對待解決問題的模型結構 和參數進行編碼，一般用字符串表示，這個過程就將問題符號化、離散化了。也有在連續 空間定義的GA(Genetic Algorithm in Continuous Space, GACS)，暫不討論。

Routine mampres: To obtain amplitude response from h(exp(jw)). input parameters: h :n dimensioned complex array. the frequency response is stored in h(0) to h(n-1). n :the dimension of h and amp. fs :sampling frequency (Hz). iamp:If iamp=0: The Amplitude Res. amp(k)=abs(h(k)) If iamp=1: The Amplitude Res. amp(k)=20.*alog10(abs(h(k))). output parameters: amp :n dimensioned real array. the amplitude-frequency response is stored in amp(0) to amp(n-1). Note: this program will generate a data file "filename.dat" . in chapter 2

Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram.
