I ve written some many years ago dynamic Huffman algorithm to compress and decompress data. It is mainly targeted to data with some symbols occuring more often than the rest (e.g. having some data file consisted of 3 different symbols and their total number of occurence in that file s1(1000), s2(200), s3(30) so the total length of file is 1000+200+30=1230 bytes, it will be encoded assigning one bit to s1 and 2 bits to s2, s3 so the encoded length will be 1*1000+2*(200+30)=1460 bits=182 bytes). In the best case the file consisted of just one symbol will be encoded with compression ratio as 1:8. Huffman coding is used in image compression, however in JPEG2000 arithmetic codec is imployed.

Today s ActionScript-based applications require increasingly sophisticated architectures and code. This book aids intermediate and advanced ActionScript developers in learning how to plan and build applications more effectively. You ll learn how to apply design patterns as solutions to common programming scenarios. Beyond a reference, Advanced ActionScript with Design Patterns is a practical guide complete with sample mini-applications illustrating each design pattern. The accompanying CD includes a trial version of Flash 8 along

Modern C++ Design is an important book. Fundamentally, it demonstrates generic patterns or pattern templates as a powerful new way of creating extensible designs in C++--a new way to combine templates and patterns that you may never have dreamt was possible, but is. If your work involves C++ design and coding, you should read this book. Highly recommended.-Herb Sutter。好書！

Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns.
This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.

A MATLAB GUI platform for realizing the radiation pattern of narrowband beamformer with random array geometry. User can specify the array geometry, directions of incoming signals, noise power, and the type of beamformer. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays. You need both randomarray.fig and randomarray.m to work.
