Therefore, the rational development, scientific application, and effective control of pesticides are very important. In this paper, from the perspectives of pesticide discovery, formulation processing, application mode, residue monitoring, and pollution elimination and prediction, trends in the research progress and development of pesticides in China were systematically summarized to provide an important reference for the development of pesticides with high efficiency and low risk and for the reduction of pesticide application.展开更多
The non-functional QoS (quality of service) information helps us to select a proper Web-service from the web applications, by using component services such as UDDI[1](Universal Description, Discovery, and Integration)...The non-functional QoS (quality of service) information helps us to select a proper Web-service from the web applications, by using component services such as UDDI[1](Universal Description, Discovery, and Integration) and MDS(Monitoring and Discovery System). MDS is a suite of web services to monitor and discover resources and service on Grids, but MDS only based on function aspects. This paper studies on an approach to provide the QoS information and a discovery model by using MDS and gives a system deployment and implementation plan. The simulation results show that the method is effective in service discovery.展开更多
