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.

The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.

This a very simple Yee algorithm 3D FDTD code in C implementing the free space form of Maxwell s equations on a Cartesian grid. There are no internal materials or geometry. The code as delivered simulates an idealized rectangular waveguide by treating the interior of the mesh as free space/air and enforcing PEC (Perfect Electric Conductor) conditions on the faces of the mesh.

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.

I. Introduction This code exploits a previously undisclosed vulnerability in the bit string decoding code in the Microsoft ASN.1 library. This vulnerability is not related to the bit string vulnerability described in eEye advisory AD20040210-2. Both vulnerabilities were fixed in the MS04-007 patch. II. Screenshots $ ./kill-bill.pl . kill-bill : Microsoft ASN.1 remote exploit for CAN-2003-0818 (MS04-007) by Solar Eclipse <solareclipse@phreedom.org> Usage: kill-bill -p <port> -s <service> host Services: iis IIS HTTP server (port 80) iis-ssl IIS HTTP server with SSL (port 443) exchange Microsoft Exchange SMTP server (port 25) smb-nbt SMB over NetBIOS (port 139) smb SMB (port 445) If a service is running on its default port you don t have to specify both the service and the port. Examples: kill-bill -s iis 192.168.0.1 kill-bill -p 80 192.168.0.1 kill-bill -p 1234 -s smb 192.168.0.1

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

这是一个基于M/M/S类型的排队论仿真程序。M/M/S表示到达时间为负指数分布,服务时间为负指数分布,服务设备数量为S个的排队系统。 (1)到达模式:严格意义上讲是一个接着一个到达,而且到达时间间隔服从参数为mean_arr的负指数分布; (2)服务模式:服务台的数量为server_num,且每个服务台服务一个顾客的服务时间服从参数为mean_serv的负指数分布; (3)排队规则:满足先进先服务,服务快的先离开的规则。
