300 km 傳輸線和功率補償仿真 The circuit below represents an equivalent power system feeding a 300 km transmission line. The line is compensated by a shunt inductor at its receiving end. A circuit breaker allows energizing and de-energizing of the line. To simplify matters, only ONE of the three phases is represented. The parameters shown in the figure are typical of a 735 kV power system.

Digital Signature Algorithm (DSA)是Schnorr和ElGamal簽名算法的變種，被美國NIST作為DSS(DigitalSignature Standard)。算法中應用了下述參數： p：L bits長的素數。L是64的倍數，范圍是512到1024； q：p - 1的160bits的素因子； g：g = h^((p-1)/q) mod p，h滿足h < p - 1, h^((p-1)/q) mod p > 1； x：x < q，x為私鑰 ； y：y = g^x mod p ，( p, q, g, y )為公鑰； H( x )：ONE-Way Hash函數。DSS中選用SHA( Secure Hash Algorithm )。 p, q, g可由一組用戶共享，但在實際應用中，使用公共模數可能會帶來一定的威脅。簽名及驗證協議如下： 1. P產生隨機數k，k < q； 2. P計算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 簽名結果是( m, r, s )。 3. 驗證時計算 w = s^(-1)mod q u1 = ( H( m ) * w ) mod q u2 = ( r * w ) mod q v = (( g^u1 * y^u2 ) mod p ) mod q 若v = r，則認為簽名有效。 DSA是基于整數有限域離散對數難題的，其安全性與RSA相比差不多。DSA的一個重要特點是兩個素數公開，這樣，當使用別人的p和q時，即使不知道私鑰，你也能確認它們是否是隨機產生的，還是作了手腳。RSA算法卻作不到。

Advanced UNIX Programming is the long-awaited (19 years!) update to the 1985 original. Maybe "update" isn t the right word--of the 750-or-so pages in the new book, there are maybe two dozen paragraphs that are unchanged. The original covered about 70 system calls, and the new ONE covers about 300. （這是Advanced UNIX Programming的附書源碼）

C/C++ Reference There are no "Introduction to Programming" tutorials here. This site is meant to be used by more-or-less experienced C++ programmers, who have a good idea of what they want to do and simply need to look up the syntax.

非常好的優化算法的書，詳細介紹了蟻群算法和粒子群算法以及相關的matlab工具箱，講了理論和應用給出了工具箱的下載地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If ONE of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a position and a velocity. These particles wander around the hyperspace and remember the best position that they have discovered. They communicate good positions to each other and adjust their own position and velocity based on these good positions.

It is an experimental testing for python M2Crypto module. M2Crypto is not well document. User may not know how to use SHA256 when signing and verify with RSA. It also have not enough document to show how to use DES to encrypt and decrypt. Here also includes source codes for performance evaluation of the algorithms. This experimental program explore all this issue and may be helpful for some ONE who using python for doing encryption with RSA and DES.

This application report presents basic code for initializing and operating the TMS320LF240x DSP devices. Two functionally equivalent example progra ms are presented: ONE written in assembly language and the other in C language. Detailed discussions of each program are provided that explain numerous compiler and assembler directives, code requirements, and hardware-related requirements. The programs are ready to run on either the TMS320LF2407 Evaluation Module (EVM) or the eZdsp LF2407 development kit. However, they are also intended for use as a code template for any TMS320LF240x (LF240x) or TMS320LF240xA (LF240xA) DSP target system.

The download includes the kernel source code, and a demo application for EVERY RTOS port. See http://www.freertos.org/a00017.html for full details of the directory structure and information on locating the files you require. The easiest way to use FreeRTOS is start start with ONE of the demo application projects. Once this is running the project can be modified to include your own source files. This way the correct files and compiler options will be automatically included in your application. + The Source directory contains the real time kernel source files for every port. The kernel itself is only 3 files. + The Demo directory contains the demo application source files for every port. + The TraceCon directory contains the trace visualisation exe file. See the readme files in the respective directories for further information.
