This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations for the Gaussian pulse waveforms. The first derivative is considered to be the monocycle or monopulse as discussed in most papers. The second derivative is the waveform generated from a dipole antenna used in a UWB system. Other information is contained in the file.

檢測(cè)windows下rootkit對(duì)文件的隱藏。some usermode overwrites first few bytes of ZwQueryDirectoryFile and that trick will fail then :( So, you will probably need a small database of the correct indexes for all Windows versions

eForth is a small portable Forth design for a wide range of microprocessors. This is the first implementation for 8086. As machine dependency is consolidated into 31 code words, moving eForth to other CPU s will be much less of a chore comparing to other Forth models.

* Function: * 1. Replace the first oldstr with newstr in srcstr * Arguments: * IN : * srcstr * oldstr * newstr * OUT : * srcstr * Return: * 1. If find and replace one oldstr with newstr in srcstr , return 1 * 2. If find no oldstr in srcstr , return 0 * 3. If error (malloc return NULL) return -1 * Notes: * 1. srcstr should be large size enough.

比如源程序sum ∶= first+count*10可生成四元式序列，如圖1.7所示，其中ti(i=1,2,3)是編譯程序生成的臨時(shí)名字，用于存放運(yùn)算結(jié)果的。 圖1.7 id1:= id2 + id3 * 10的四元式序列
