The development of a data acquisition card based on USB bus is introduced in this article.It first describes the configuration and principle of this card in the part of hardware design,and then the application program and device driver in the part of software design.Data acquisition program in firmware is also discussed.Finally,this data acquisition card is tested and evaluated in a program developed by Lab Windows CVI,which shows that this car is stable and reliable
The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. This document introduces the concepts of
Switching P and I slices, part of the Extended Profile of H.264.
The Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T VCEG are finalising a new standard for
the coding (compression) of natural video images. The new standard [1] will be known as H.264 and
also MPEG-4 Part 10, “Advanced Video Coding”. The standard specifies two types of entropy coding:
Context-based Adaptive Binary Arithmetic Coding (CABAC) and Variable-Length Coding (VLC).
The Variable-Length Coding scheme, part of the Baseline Profile of H.264, is described in this
document.
UC Library Extensions
UnderC comes with a pocket implementation of the standard C++ libraries, which is a reasonably faithful subset. This documentation describes those UnderC functions and classes which are not part of the C++ standard.
UC Library
Builtin functions:
Most of these are standard C functions, but there are a few unique to the UnderC system which give you runtime access to the compiler. You may evaluate expressions, execute commands, compile code, etc.
* Expands the text in expr using the UnderC preprocessor, putting the result
into buff.
void uc_macro_subst(const char* expr, char* buff, int buffsize)
* Executes a UC #-command, like #l or #help.
uc_cmd() expects the name of the command, _without_ the hash,
e.g. uc_cmd("l fred.cpp") or uc_cmd("help").
void uc_cmd(const char* cmd)
* Evaluates any C++ expression or statement will return non-zero if
unsuccessful.

Fixed-point description of commendation G.729 with ANNEX B Coding of Speech at 8 kbit/s using Conjugate-Structure Algebraic-Code-Excited Linear-Prediction (CS-ACELP) with Voice Activity Decision(VAD), Discontinuous Transmission(DTX), and Comfort Noise Generation(CNG).
ATViewer is a component for Delphi/C++Builder, which allows to view files of various types. There is no edit possibility, just quick view - so it s useful to implement "View file" feature in your Delphi/C++Builder application.
The following view modes are implemented:
Text, Binary, Hex, Unicode: all files, of unlimited size. Plain file dump is shown. Used ATBinHex component: only visible part of file is loaded into memory. Modes are suitable for huge files and files of unknown type.
RTF/UTF-8: RTF and UTF-8 encoded texts. File is shown using RichEdit control.
Image: all general image formats: BMP JPG ICO GIF PNG... File is shown using ATImageBox component.
Multimedia: all file types supported by MS Windows Media Player: AVI MPEG WMV MP3... File is shown using WMP ActiveX control.
Internet: all file types supported by MS Internet Explorer: HTML XML DOC XLS... File is shown using MSIE ActiveX control.
Plugins: all files supported by Total Commander Lister plugins.
this application program demonstrate programming and simulation of the on-chip CAN (controller area network) interface of the C167/ST10-F168. The sample source code can be compiled using keil C166 compiler. To test the program you may use the uVision2 debugger/simulator that is part of keilPK166 package.

sql equipment management system for the Institute of Laboratory office automation management system an important part of it can lend to the return of the equipment scrapped and a new standardized management, thereby increasing efficiency and avoiding waste of resources.
background database using Access, prospects of development tools using Visual Basic.
The system uses ADO data access technology, and each database table and operation of the field to the type of package, which succeeded in object-oriented programming thinking applied to the database application design.
Many problems in statistical pattern recognition begin with the preprocessing of multidimensional signals, such as images of faces or spectrograms of speech.
