Fit a multivariate gaussian mixture by a cross-entropy method. Cross-Entropy is a powerfull tool to achieve stochastic multi-extremum optimization.

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm i ...

Anyone who interacts with today s modern databases needs to know SQL (Structured Query Language), the standard language for generating, manipulating, and retrieving database information. In recent years, the dramatic rise in the popularity of relational databases and multi-user databases has fueled ...

This zip file describes how to generate a clock on the PCK pin using the PMC running under AT91RM3400DK with Green hills 3.6.1 Multi&reg 2000 Software Tool. Includes main.html file for help.

This document contains a specification for a new low pin count bus interface, dubbed LPC, that will be added to future Intel chip-sets. The target audience for this document are system and component designers.

To estimate the input-output mapping with inputs x ％ and outputs y generated by the following nonlinear, ％ nonstationary state space model: ％ x(t+1) = 0.5x(t) + [25x(t)]/[(1+x(t))^(2)] ％ + 8cos(1.2t) + process noise ％ y(t) = x(t)^(2) / 20 + 6 squareWave(0.05(t-1)) + 3 ％ + time varying measur ...

You imagine? Right, there s more than one possibility, this time I ll give you tree. One for your private data, one for the common data in order to receive data from other applications like Excel, WinWord etc. and at last, I ll give you a handy-dandy class you can derive ANY MFC object from, to make ...

delphi中的几个技巧 1、判断一个字符串是否包含于另外一个字符串的方法 例如：if pos( ab , abcd )<>0 then messagedlg( ab是包含于abcd ,mtConfirmation,[mbYes, mbNo],0) pos(obj,target) 在target字符串中找出第一个出现obj的第一个字符位置,如果找不到,返回0. 2、如何使窗口全屏，类似游戏一样，而不是窗口的最大化! ...

这是我自己写的用于嵌入式设备的CGI程序，ANSI C编写，嵌入式Linux中使用。这些CGI代码是我在CGIC库的基础上加上了常用的一些外围功能模块函数，比如读写配置文件等。其中比较重要的是我自己实现的session控制、页面模板方式（模板标签替换）和web多语言版本的一种我自己的实现方法。请参阅cgi_functions.c、session.c和mul ...

A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconst ...
