A systematic pot test was performed both in summer and autumn, which the purification efficiency to the polluted urban storm runoff was studied. The orthogonal method was applied to design the experiment. 24 plastic pots were divided into eight groups, and each group included a blank sample and two parallel samples for comparison. The results showed that: (1) the removal rate of CODCr was almost higher...
The purpose of this article is to study advantages and disadvantages about discriminant analysis with five linear methods. And through comparison,we can obtain that there are not absolute rules to tell us which is best in discriminant analysis with linear methods. The conditions in practice determine mostly the power of five methods. Through this case,we find that FDA is a most stable discriminant...
This paper presents a composite service execution engine, which can support human tasks and improve their execution by an approach of human task scheduling. In the approach, the performance evaluation model is proposed, which can reflect the performance of the human service resources objectively and comprehensively. Based on this model, the initial scheduling as well as re-scheduling methods for solving...
Web services run in a highly dynamic environment (the Internet) which makes the composite service will face multiple exceptions in its execution. Thus, it needs to take effective actions to deal with the errors causing the exceptions. Then, by such actions, composite service can adapt to the dynamics and complexity of its execution environment. Since accurately identifying the error source which causes...
