The VGA example generates a 320x240 diffusion-limited-aggregation (DLA) on Altera DE2 board. A DLA is a clump formed by sticky particles adhering to an existing structure. In this design, we start with one pixel at the center of the screen and allow a random walker to bounce around the screen until it hits the pixel at the center. It then sticks and a new walker is started randomly at one of the 4 corners of the screen. The random number generators for x and y steps are XOR feedback shift registers (see also Hamblen, Appendix A). The VGA driver, PLL, and reset controller from the DE2 CDROM are necessary to compile this example. Note that you must push KEY0 to start the state machine.

The literature of cryptography has a curious history. Secrecy, of course, has always played a central role, but until the First World War, important developments appeared in print in a more or less timely fashion and the field moved forward in much the same way as other specialized disciplines. As late as 1918, one of the most influential cryptanalytic papers of the twentieth century, William F. Friedman’s monograph The Index of Coincidence and Its Applications in Cryptography, appeared as a research report of the private Riverbank Laboratories [577]. And this, despite the fact that the work had been done as part of the war effort. In the same year Edward H. Hebern of Oakland, California filed the first patent for a rotor machine [710], the device destined to be a mainstay of military cryptography for nearly 50 years.

Please read this document before attempting to compile and run the libraries and applications! The projects must be compiled in a particular order. Standard support questions are about compiler and/or linker errors that are generated when users try to compile the projects in the wrong order. Other information of interest is available here, so read the entire document fi rst. Wild Magic Version 2.1 is what ships with the fi rst printing of the Game Physics book. Some of the applications that are referenced in the book did not make it onto the CD–ROM for the book. Version 2.2 contains those applications, plus more

数据加密算法（Data Encryption Algorithm，DEA）的数据加密标准（Data Encryption Standard，DES）是规范的描述，它出自 IBM 的研究工作，并在 1997 年被美国政府正式采纳。它很可能是使用最广泛的秘钥系统，特别是在保护金融数据的安全中，最初开发的 DES 是嵌入硬 件中的。通常，自动取款机（Automated Teller Machine，ATM）都使用 DES。文件是DES代码的VHDL描述

In this paper, we describe the development of a rapidly reconfigurable system in which the users’ tacit knowledge and requirements are elicited via a process of Interactive Evolution, finding the image processing parameters to achieve the required goals without any need for specialised knowledge of the machine vision system. We show that the resulting segmentation can be quickly and easily evolved from scratch, and achieves detection rates comparable to those of a hand-tuned system on a hot-rolled steel defect recognition problem.
