Three fractal methods are applied to the time-scaling properties analysis of water COD series from Poyang Lake Inlet and Outlet in China. 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. This work can be helpful to improvement of modeling of lake water quality.

To guarantee the grain’s safe storage, it’s necessary to strictly control the stored-grain’s internal and external influence factors such as temperature, moisture, humidity and pests. 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.

The ControlNet network is designed to be the central communication architecture for interoperating automation products. 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. Simulation results and conclusions are presented.

Active carbon-ceramic sphere as support of ruthenium catalysts were evaluated through the catalytic wet air oxidation (CWAO) of resin effluent in a packed-bed reactor. Active carbon-ceramic sphere and ruthenium catalysts were characterized by N2 adsorption, CO chemisorption and SEM measurements. BET surface area and total pore volume of active carbon(AC) in active carbon-ceramic sphere increase with increasing KOH-to-Carbon ratio, AC in the sample KC-120 possesses values as high as 1100 m2g-1 and 0.69 cm3g -1(carbon percentage: 4.73 wt. %), especially. Active carbon-ceramic sphere supported ruthenium catalysts were prepared using the RuCl3 solution impregnation onto KC-120, the ruthenium loading was fixed at 1-5 wt. % of AC in the support. As optimum catalyst, the 3 wt. % Ru/KC-120 catalyst displays the higher stability in the CWAO of resin effluent during 30 days. Chemical oxygen demand (COD) and phenol removal were about 92% and 96% at the reaction temperature of 200 oC, oxygen pressure of 1.5 MPa, the water flow rate of 0.75 L h-1 and the oxygen flow rate of 13.5 L h-1.
