1. Download the version you want: * Version 1.3.4 (30 Aug 2007) -- this is the latest version for UNIX/Linux and Windows * Previous versions 2. Unzip the file, which will create a directory called klt and place all the files there 3. Compile and run the code * On UNIX / Linux, move to the klt directory, type make. Now try some examples, by typing example1, etc. * For Microsoft Visual C++ 6.0, open the klt.dsw file, compile, and run. Change the constant in main.cpp to run the different examples. * For Microsoft Visual Studio .Net/7/8, open the klt.sln file, compile, and run. Change the constant in main.cpp to run the different examples. 4. Notice that, for your convenience, unofficial copies of the User and Reference Manuals can be found in the doc directory.

Emdros is a text database middleware-layer aimed at storage and retrieval of "text plus information about that text." This information could be linguistic analyses or other annotations. Emdros provides an abstraction of text that makes it well suited to storing /syntactic analyses/ of text, but other linguistic information is supported as well. Emdros comes with a query-language, MQL, that enables powerful queries. Emdros acts as a middleware-layer between a client (not provided) and a database back-end. Currently, PostgreSQL, MySQL, and SQLite (2 and 3) are supported, but other back-ends can easily be added.

In communication systems channel poses an important role. channels can convolve many different kind of distortions to our information. In perticular wireless channels multipath distortion is sevear. and more sevear is such distortion is random. To handle this, multipath affected channels require Equalizers at receaver end. such equalizer uses different learning Algorithms for identifying channels continuously. This project is VHDL implementation of LMS learning algorithm with pipelined architecture. so this implementation can work with higher data rates with less clock speed requirments and so with less power consumpiton It uses Fixed point arithmatic blocks for filtering so suitable for coustom asic.

This tutorial was prepared for our freshman engineering students using the student version of MATLAB, because symbolic computations are covered in almost no introductory textbook. We are pleased to make it available to the international community, and would appreciate suggestions for its improvement. MATLAB’s symbolic engine permits the user to do things easily that are difficult or impossible to do numerically
