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.
ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the Mechanical Engineering at Glasgow Universtity. The software which can transfer
data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.
軟件測(cè)試的目的決定了如何去組織測(cè)試。如果測(cè)試的目的是為了盡可能多地找出錯(cuò)誤，那么測(cè)試就應(yīng)該直接針對(duì)軟件比較復(fù)雜的部分或是出錯(cuò)比較多的位置。如果測(cè)試目的是為了給最終用戶提供具有一定可信度的質(zhì)量評(píng)價(jià)，那么測(cè)試就應(yīng)該直接針對(duì)在實(shí)際應(yīng)用中會(huì)經(jīng)常用到的模塊重點(diǎn)測(cè)試。不同的機(jī)構(gòu)會(huì)有不同的測(cè)試目的；相同的機(jī)構(gòu)也可能有不同測(cè)試目的，可能是測(cè)試不同區(qū)域或是對(duì)同一區(qū)域的不同層次的測(cè)試。在談到軟件測(cè)試時(shí)，許多人都引用Grenford J. Myers在《The Art of Software Testing》一書(shū)中的觀點(diǎn)：
This package implements a Kalman filter as described in the
paper "A Statistical Algorithm for Estimating Speed from Single Loop
Volume and Occupancy Measurements" by D. J. Dailey.
