ns2初学者原创程序，为三节点有线连接tcl文件，以及分析throught,loss,delay参数的awk文件和运行结果。并对不同连接带宽参数下对脚本进行修改，分析不同情况下参数的变化。适合刚刚使用ns2以及awk的初学者。

NIST Net – A Linux-based Network Emulation Tool, It is a raw IP packet filter with many controllable channel parameters such as packet loss ratio, jitter, bandwidth variation, delay, and network buffer size. To simulate different network environments

These routines model tropospheric radiowave propagation over variable terrain and calculates propagation loss vs. height and range. Propagation loss is displayed in dB contours on a height vs. range plot. TPEM is based on the split-step Fourier PE method and was originally developed from an early PE ...

The TMS320VC5506/C5507/C5509A USB peripherals can be clocked from either the USB APLL or the USB DPLL. Since the APLL is inherently more noise tolerant and has less long-term jitter than the DPLL, it is recommended that you switch to it for any USB operations.

To review what a metaball is, and how to render them and to describe a new optimization I ve made for rendering metaballs. For complex scenes, it can render hundreds of times faster, though I m certain others have discovered this trick as well. It does very slightly change the characteristic ...

A combined space鈥搕ime block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-multiple-output systems is proposed. It is proved that the STBC-EST is capable of shifting hardware complexity from the receiver to the transmitter without any bit error rate (BER) performance loss. A ...

择PCB板材必须在满足设计需求和可量产性及成本中间取得平衡点。设计需求包含电气和机构这两部分。通常在设计非常高速的PCB板子(大于GHz的频率)时这材质问题会比较重要。例如，现在常用的FR-4材质，在几个GHz的频率时的介质损(dielectric loss)会对信号衰减有很大的影响，可能就不合用。就电气而言，要注意介电常数(dielectr ...

I implemented a perfect file transfer OCX client/server. I created a perfect function to parse and split the data. The source file size is equal to destination. NO LOSS OF DATA in the packets!

G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion to its incidence.Despite a usually good prognosis,GBS is a particularly frightening and often life- altering experience for those diagnosed with the disorder.Many patients are acutely aware of the rapi ...

Blocking CoThe aim of this toolbox is to compute blocking probabilities in WDM networks. This work was based on [1], [2], [3], [4] and user is referred to those papers for deeper study. Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources.Computat ...
