The results show that these COD series are characterized by long-term memory, 1/f noise and multifractal scaling, and these characteristics have obvious difference between the Lake Inlet and Outlet. The comparison results suggest that monofractal and multifractal parameters can be quantitative dynamical indexes reflecting environmental capacity of Poyang Lake. Furthermore, we investigate the frequency-size distribution of COD series from Poyang Lake Inlet and Outlet. Our findings suggest that water COD is an example of a self-organized criticality (SOC) process. Based on concept of self-organized criticality, we analysis the cause that different scale-free power-law behavior between COD series from Poyang Lake Inlet and Outlet.

The application of information fusion techniques on monitoring and controlling system of stored-grain condition is a useful consideration. In this paper, a new method based on multi-parameter and two stage information fusion techniques is proposed. In the process of fusion, the BP neural network technique and D-S evidence theory are mainly applied. This method,characterized by sufficiently utilizing the effective detected condition data, optimizing homogeneous data and considering the complementation of the different data source, improves the whole stored-grain condition’s monitoring and control system’s reliability.","PeriodicalId":6371,"journal":{"name":"2010 International Conference on Challenges in Environmental Science and Computer Engineering","volume":"33 1","pages":"435-438"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86375621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides fast, deterministic scheduled data transfer for control purposes and unscheduled non–time–critical messaging for configuration and house–keeping on the same network. This is accomplished by partitioning the bandwidth into a scheduled portion that is guaranteed to be delivered within a specified Network Update Time and an unscheduled portion that is essentially the time remaining after the scheduled traffic is handled. A critical user-supplied parameter for ControlNet is the Network Update Time or NUT. In this article, we studied the critical parameter of the ControlNet network when used in a control situation.
