And Control

Greenhouse environment system is an often nonlinear, change and inertia complex system. It is very hard to build math model and control. Since moisture and temperature have a influence to crops grow, we select them to build the manner of control system, applying fuzzy control system to design moisture and temperature controller, and to write fuzzy control program based PLC, then we should observe the factual control effect. The result of system running show: when temperature is set to 25oC and moisture is 80%RH, the process of control is stable and the system is very stable, it can meet the greenhouse requirement.

With the continuous development of milling machine, the normal milling machine was not suitable with modern processing. In order to adapt to the requirements of modern production process and quality, the electrical control system of milling machine need be improved. The electrical control system and circuit of X62W milling machine is analyzed and designed. The PLC program is compiled. All of it is proved to be reasonably and feasibly based on the experimental results.

Risk Coverage

AbstractWe analyze the effects of Price Loss Coverage (PLC), Agriculture Risk Coverage (ARC), individual revenue protection insurance (RP), and Supplemental Coverage Option (SCO) on the RP coverage level, certainty equivalent, and program payments. The model is calibrated to a representative wheat farm in Mitchell County in Kansas to analyze the effects of various policies. The result highlights that when insurance is framed as an investment, cumulative prospect theory predicts farmers’ coverage decisions accurately at 70%. ARC or PLC program increases the RP coverage level to 75%, but PLC and SCO jointly decrease the RP coverage level to 70%.

Recently, network attacks launched by malicious attackers have seriously affected modern life and enterprise production, and these network attack samples have the characteristic of type imbalance, which undoubtedly increases the difficulty of intrusion detection. In response to this problem, it would naturally be very meaningful to design an intrusion detection system (IDS) to effectively and quickly identify and detect malicious behaviors. In our work, we have proposed a method for an IDS-combined incremental extreme learning machine (I-ELM) with an adaptive principal component (A-PCA). In this method, the relevant features of network traffic are adaptively selected, where the best detection accuracy can then be obtained by I-ELM. We have used the NSL-KDD standard dataset and UNSW-NB15 standard dataset to evaluate the performance of our proposed method. Through analysis of the experimental results, we can see that our proposed method has better computation capacity, stronger generalization ability, and higher accuracy.
