- ：面向对象软件测试是面向对象软件开发的重要一环，是保证软件质量提高软件可靠性的关键。结合传统软件测试 的方法和技术，并针对面向对象软件所具有的特征，将面向对象软件测试层次划分为3层：类测试、类簇测斌和系统测试， 讨论了面向对象软件测试的测试方法和解决方案，并以销售系统为例，给出了相应层次的具体测试策略。-: object-oriented software testing is an object-oriented software development an important pa
Webdevelopments
- Web服务器又称WWW服务器、网站服务器或站点服务器，就是将本地的信息用超文本组织，为用户在Internet上搜索和浏览信息提供服务。从本质上来说，Web服务器实际上就是一个软件系统。一台计算机可以充当多个Web服务器。为提高用户的访问效率，一般情况下一台计算机只充当一个Web服务器；为提供大量用户的访问，多台计算机可以形成集群，只提供一个Web服务。通常将只充当一个Web服务器的一台计算机叫做Web服务器。-Web server, also known as WWW server, web s

GeoLPM_ATNAC_2004
- One of the major weakness of existing peer-to-peer networks is that their overlay structures do not match well with the physical underlying network topology. In this paper, we present a Geographical Longest Prefix Matching (Geo-LPM) scheme wh
Topology_aware_ICC_2005
- One of the major weaknesses of existing peer-to-peer (P2P) networks is that their overlay structures do not correlate to the physical underlying network topology. As a result, the overlays waste network resources and introduce excessive end-toe

mpiquiqsort
- Originally the definition of sorting in MPI is that lists are scattered around a series of working clusters before sorting. After sorting they still are scattered in those machines except that each segment is sorted and if one element in A is bigger
k-means
- Clustering is the unsupervised classification of patterns (observations, data items, or feature vectors) into groups (clusters). The clustering problem has been addressed in many contexts and by researchers in many disciplines this reflects its
A-NOVEL-SKIN-YCBCR-COLOR-SPACE
