Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

This is a desktop application written in java which sends email using gmail smtp. You do not need to go to the browser to send email. If you do not have a gmail account that is ok too because you can send email by a default account and of course by your own account. You need jdk 1.6 or higher to run it.

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.

barcode component The sourcecode does not rely on any language specific features. It will probably compile under Delphi 8 and higher. Kylix ? barcode component does not use any special Windows API functions so it should work with Kylix (untested).

A digital filter structure for wideband filtering is proposed. It consists of two allpass filters and a linearphase FIR filter. One major advantage of this structure is that the allpass filters are functions of zM which implies that the maximal sample frequency is M times higher for this structure than for the corresponding conventional structures.

FERRET - a broadcast analysis tool This tool is designed to demonstrate the problem of "data seapage". The average machine broadcasts a lot of information about itself on open networks. This tool captures and organizes this information. This code is extremely low quality, hacked together in order to demonstrate the problem at the BlackHat Federal 2007 conference. higher quality code should be available around May 2007 on our website at http://www.erratasec.com.

A java application - processing which can be downloaded free from processing.org Here it uses a free library - OpenCV - made by intel. .. to convert all the pixels in an image - in fact in a movie - a capture from the webcam. If the color of a pixel is "higher" comparing to a threshold it turns black - otherwise it becomes white.

SrcDecompiler is about creating a Delphi program decompiler. The program is written for Delphi 4 or higher and will not work with a previous version of Delphi. Also it can only decompile programs written with the same version of Delphi as the decompiler is compiled with.
