Der Aufbau eines kleinen Frequenzzä hers ist dank der heutigen Atmel AVR Controller oder aber auch der Mikrochip PIC Controller (um nur zwei zu nennen) relativ schnell und einfach aufzubauen. Dazu werden meist die internen Timer/Counter des Controllers benutzt. Der Counter wird durch das anliegende Signal am Takteingang hoch gezä hlt. Durch den Timer wird dann der Counter zu einen festgelegten Zeitpunkt stetig ausgelesen und zurückgesetzt. Nehmen wir mal an ein 20Hz TTL-Signal taktet den Counter so steht nun im Counterregister nach einer Sekunde der Wert 20. Dieser wird nur noch auf dem Display oder serielle Schnittstelle ausgegeben. Nach einer erfolgreichen Auktion bei einen einschlä gigen Internet Auktionshaus, erwarb ich einige 7Segment Anzeigen, hierfür musste ich mir etwas einfallen lassen. Heraus kam somit ein besagter kleiner preiswerter 50MHz Frequenzzä hler, den ich nicht vorenthalten will.

linux下用C语言写的聊天程序！/*BUG and NOTE: Not join protect to Shared Memory Segments,example Semaphore Arrays. Not check the parameters validity. When transmit may be error. If the client program no right exit,others cannot know,the service program shouldbe check the client program whether exist timing. The program when exit(), it do not delete the Shared Memory Segments,you maybe use atexit() but the program have some processes. When one process is exit(),others is continue. The service program s action is few. And so on. */

MATFOR FFT Visual Fortran program. MATFOR Extensions, as implied in the name, are data or components external to MATFOR modules that can be used to add versatility to MATFOR programs. Currently there are two types of extensions available with MATFOR, they are MATLAB Interface and Tecplot FileIO. MATLAB Interface, a new feature in MATFOR 4.1, provides MATFOR users access to MATLAB functions so they can obtain functionality that has not been built into MATFOR. The ability of using MATLAB functions makes MATFOR an ideal tool for those who create prototypes using MATLAB, then do implementation in C++ and other programming languages. Through the use of MATFOR, users may perform quick results comparisons between MATLAB and other languages.

GNU Common C++ is a very portable and highly optimized class framework for writing C++ applications that need to use threads and support concurrent sychronization, and that use sockets, XML parsing, object serialization, thread-optimized String and data structure classes, etc. This framework offers a class foundation that hides platform differences from your C++ application so that you need not write platform specific code. GNU Common C++ has been ported to compile nativily on most platforms which support either posix threads, or on maybe be used with Debian hosted mingw32 to build native threading applications for Microsoft Windows.

In this paper, we present LOADED, an algorithm for outlier detection in evolving data sets containing both continuous and categorical attributes. LOADED is a tunable algorithm, wherein one can trade off computation for accuracy so that domain-specific response times are achieved. Experimental results show that LOADED provides very good detection and false positive rates, which are several times better than those of existing distance-based schemes.

This program is a new way to estimate the coherence function. It s based on the MVDR and is much more reliable than the classical Welch s method implemented in MATLAB. There are 2 programs: the main program called coherence_MVDR.m and and an example, called illustrate.m, that calls the main function to show how it works. There also included 2 papers that we published on this algorithm.
