Description The art galleries of the new and very futuristic building of the Center for Balkan Cooperation have the form of polygons (not necessarily convex). When a big exhibition is organized, watching over all of the pictures is a big security concern. Your task is that for a given gallery to write a program which finds the surface of the area of the floor, from which each point on the walls of the gallery is visible. On the Figure 1. a map of a gallery is given in some co-ordinate system. The area wanted is shaded on the Figure 2.

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a Figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

ES（The Advanced Encryption Standard）是美国国家标准与技术研究所用于加密电子数据的规范。它被预期能成为人们公认的加密包括金融、电信和政府数字信息的方法。 AES 是一个新的可以用于保护电子数据的加密算法。明确地说，AES 是一个迭代的、对称密钥分组的密码，它可以使用128、192 和 256 位密钥，并且用 128 位（16字节）分组加密和解密数据。与公共密钥密码使用密钥对不同，对称密钥密码使用相同的密钥加密和解密数据。通过分组密码返回的加密数据 的位数与输入数据相同。迭代加密使用一个循环结构，在该循环中重复置换（permutations ）和替换(substitutions）输入数据。Figure 1 显示了 AES 用192位密钥对一个16位字节数据块进行加密和解密的情形。

Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer Figure out how to piece together the APIs contained in these packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.
