Abstract: The electrostatic discharge detonating gas simulation experiment system based on Nios II is developed in this paper.This system uses flexible and highly efficient SOPC technology,which embeds many functional modules.The system can simulate the mine gas environment, measure the oxygen, temperature and the gas concentration that most likely detonating gas, and real-time display in the LED screen, so as to obtain important data of gas explosion in coal environmental, which provide theoretical and experimental basis for farmulating standards of electrostatic security of human body and the safety of production in coal mine. It can conduct a series of experiments about electrostatic discharge of human body detonating gas mixture.

Abstract: In order to improve the accuracy of financial achievement, this paper applies a new forecast model of the Increased memory type least squares support vector machine base on neighborhood rough set and quadratic Renyi-entropy on the basis of the traditional support vector machine prediction model. The paper also independently derives the entropy fit for the financial distress prediction which is in discrete sequence, as well as the expression of support vector machine kernel function. The experimental results show that the improved model is significantly superior to the traditional LS-SVM as well as the standard support vector machine prediction model, regardless of the forecast accuracy , training samples number.

Abstract: Unlike traditional routing schemes that route all traffic along a single path, multipath routing strategies split the traffic among several paths in order to ease congestion. It has been widely recognized that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. According to the characteristics of ant colony algorithm and the ideal of multipath routing. This paper proposes a QoS multipath routing on ACO Algorithm. ACO was improved in three aspects. As a ant selects the next hop, the utilization ratio of router's buffer queue is added into the criterion of selection, introducing the utilization ratio of link to update the global pheromone, selecting multiple paths to transfer data. Simulation experiments show the algorithm can achieve network loading balance, reduce the likelihood of congestion, and impove the utilization of network resources.

Abstract: It was results show that nicosulfuron and Atrazine with the different ratio have the synergized action to plants of the monocotyledon and double seed leaf weed by the indoor bioassay of crabgrass (Digitaria ciliaris) and purslane. When Atrazine: nicosulfuron = 17:3 ratio of compatibility, the co-toxicity coefficient is the largest and showing an enhancement effect of the most significant. The 20% nicosulfuron and Atrazine of Oil Miscible Flowable Concentrate was processed by ultrafine grinding in the wetting emulsifier, dispersant, thickener, solvent, were screened test to decide the best formula. This preparation showed after (0±1)°C low temperature and (54±2)°C thermostble experiment's result the outward appearance not obvious lamination, in the water the dispersivity is good, each target conforms to the Oil-based Suspension related standard.

Abstract: In this paper, we propose algorithm based reinforcement learning for spiking neural networks. The algorithm simulates biological adaptability and uses the soft-reward from environment to modulate the synaptic weight, which combines spike-timing-dependent plasticity (STDP), winner-take-all mechanism. The algorithm is tested to classify a number of standard benchmark dataset. The obtained results show the effectiveness of the proposed algorithm.

Abstract: With the development of information carriers and information recording means, non-book materials have experienced considerable changes in type and number. Moreover non-book materials play an increasingly important role in information resources construction by virtue of increasing user demand for non-book materials.At present non-book materials in the library are short of effective management and unable to meet user demand, which reduces user satisfaction and damages the image of the library. The author holds the opinion that establishing networked management of non-book materials is crucial. In order to solve this problem, the author mainly expounds 5 indispensible aspects of networked management in non-book materials: classification unification and descriptive standardization; transformation of information; networked management; establishing regional joint service system; paying attention to the copyright problem.

Abstract: A method based on neural-network is developed and applied to analyze the DSPSL filter design. Through the neural network analysis of nonlinear circuits, it can enhance the efficiency of electro-magnetic (EM) analysis techniques for DSPSL filter design. Quasi-Newton method is adopted, which has shorter training period and the faster convergence. A good agreement between ANN results and EM simulations verifies the validity of this proposed MLPNN model.

Abstract: SIR (Stepped impedance resonator) for its features in microwave design, it is paid more and more attention. The harmonic and fundamental frequency can control through the impedance ratios of the SIR structure. In theory, SIR can control the locations of any sub-harmonics, which for the miniaturization of microwave devices and the efficiency of spectrum is very useful. In this paper, a method based on ABCD matrix of 2-ports network is proposed to analyze SIR.

Abstract: Due to the low level of overvoltage withstand and over-current withstand, the overvoltage caused by direct lightning stroke, lightning-wave intrusion, lightning induction etc. can pose an enormous threat to video surveillance system device, and the lightning protection problems appear very important. Adopt effective lightning protection measures in the light of lightning harm features of the constituent parts of video surveillance system like front-end device, transmission lines, surveillance center, etc. Practice has proved that the proposed lightning protection measures can play an important role for improving the security of video surveillance system.

Abstract: The evolving rule includes random attachment and preferential attachment and so on. It forms different network formation by different attachment. In order to analyze this character, this paper put forward an evolving model. It contains two kinds of attachment: some are connected at random, and others are connected based on current structure of the network, and in the model the deleted links are considered. The degree distribution and degree exponent are obtained by mean-field approach. Then it discusses the influence of randomness on the average path length.
