Data_Structures_and_Algorithms - These notes accompany Data Structures and Algorithms II. The course, to a large extent, follows on from Data Structures and Algorithms I. However, while DS&A I focused on fundamental datastructures, DS&A II will focus on practical algorithms, applicable to a wide range of tasks. The approach will be somewhat less formal, with a little more focus on applications.

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.

The Little Green BATS is the first and so far only Dutch team in the 3D simulation league. We are a group of graduate students from the department of AI at the University of Groningen, The Netherlands. Our team name is derived from the fact that the first 3D agents in the league were balls and from the very philosophical observation that Balls Are Truly Spheres (BATS). This abbreviation reminded us of our favorite song Little Green Bag by The George Baker Selection and so the whole team name was born. We entered the competition for the first time at the 10th edition of RoboCup at Bremen, Germany. unfortunately our hard work didn t pay off that time: already in the second round we got eliminated. However, after this we had a good base to build upon and the good time we had at the event and the nice community inspired us to continue and work hard for another year. This turned out to be defiantly worth it, because in 2007 in Atlanta we managed to become vice world champions!

Object-oriented languages define objects (types of things) that know how to perform methods (specific actions). Functional languages treat programming problems like mathematical relationships. Ruby is flexible, meaning that you can program in any of these styles However, it is primarily object oriented, with some strong functional influence. This book focuses slightly more on the functional aspects of Ruby than some other books.

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity． The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions．However．there are many shortcomings in traditiona1 measurements．This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page．Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient．

The C++ standard library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, However, is not self-explanatory. To make full use of its components - and to benefit from their power - you need a resource that does far more than list the classes and their functions.

delphi 寫的delphi的程序 Handel is a free, standalone development tool created with Delphi 3 that enables you to create, compile, and run projects. Handel also supports Form Design Environments such as Delphi and can open and write units, projects, and forms created with Delphi 2 or 3. However, it is not perfectly compatible with Delphi.

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.

This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System. As a first release it s still rather rough and very much larger than desired However it is working well in an embedded product and therefore may be useful to others. Much of the code is ported from public sources including BDS Lite and KA9Q (and its derivatives) and carries copyright notices from those sources. Essentially TCP is based on KA9Q but with ideas from BSD, IP is a simple implementation supporting BSD structures, ICMP is ported from BSD, and PPP is ported from the BSD version of the distribution common to BSD, Linux, and many other systems

this directory contains the following: * The acdc algorithm for finding the approximate general (non-orthogonal) joint diagonalizer (in the direct Least Squares sense) of a set of Hermitian matrices. [acdc.m] * The acdc algorithm for finding the same for a set of Symmetric matrices. [acdc_sym.m](note that for real-valued matrices the Hermitian and Symmetric cases are similar However, in such cases the Hermitian version [acdc.m], rather than the Symmetric version[acdc_sym] is preferable. * A function that finds an initial guess for acdc by applying hard-whitening followed by Cardoso s orthogonal joint diagonalizer. Note that acdc may also be called without an initial guess, in which case the initial guess is set by default to the identity matrix. The m-file includes the joint_diag function (by Cardoso) for performing the orthogonal part. [init4acdc.m]
