Research on reliability analysis of component assembly for internetware
Journal Title: Science Paper Online - Year 2006, Vol 1, Issue 3
Abstract
Internetware is a kind of significant emerging software systems in the open, dynamic and uncertain environment (like Internet). It is built upon the coordination of the heterogeneous, autonomous software entities in the open environment. The component assembly is one of effective means to achieve the coordination among software entities in the context of Internetware. However, current approaches to software reliability are not very suitable to this kind of software systems. After surveying the status about current approaches to software reliability, this paper proposes a new approach to the reliability analysis of component assembly for Internetware, based on the reliabilities of the individual components in different application domains, the reliabilities of connections to these components and the architecture of the composition. We also analyze the sensitivity of the software reliability to the changes of the reliabilities of individual components and the connections between the components. The approach is helpful to support reliability analysis on components assembly for Internetware.

两种液体吸湿剂的除湿性能比较
对分别以溴化锂(LiBr)和氯化锂(LiCl)溶液为吸湿剂的除湿器性能进行了测试,得到了2种溶液在除湿工况下的性能数据。并将实验数据分别拟合成了关于进口参数的除湿量经验公式。基于经验公式,分析比较了2种溶液在相同的除湿装置、空气进口参...
The application of cone dynamic penetration test method to geotechnical exploration in gravel soils
The heavy and super-heavy cone dynamic penetration test is an effective means to geotechnical exploration in gravel soils. But the results of cone penetration tests are often used just as qualitative parameters or refere...
CORDIC算法在DDS中的应用
直接数字频率合成技术(DDS)是20世纪70年代初提出的一种新的频率合成技术,具有频率分辨率高,切换速度快,并且在改变时能保持相位连续,易实现频率、相位和幅度的调制等特性。在分析CORDIC算法基本原理的基础上,用一种改进的CORDIC算法...
