The purpose of this paper is to probe into the rules of medicine compounding for stroke prevention treated by Xin'an physicians by data mining. The method is in two steps. First step is to build the database of the Xin'an physical stroke prevention. Second step is to use the method of association rules contained in professional data mining software and probe into the medicine rules for stroke prevention treated by Xin'an physicians. The result is that Chenpi, Fuling, Gancao, Luxiancao, Xiqiancao, Baijili, and Shinanye which are of the seven common Chinese medical compounding prescriptions can be used for Xin'an physicians' stroke prevention. The conclusion is that we should utilize the eliminating phlegm, calming wind and clearing the channels when Xin'an physicians treat stroke problem.

Increasingly in practical applications, nonlinearity, non-Gaussianity, and constraint are considered when dealing with state estimation problems. This paper proposes a novel constrained particle filter (PF) approach for state estimation, where three constraint strategies are implemented: First, to ensure the validity of prior, prior particles are restrictedly sampled in the constraint region by a constrained inverse transform sampling method. Second, if constraints are imposed on the posterior, a constrained re-sampling method, similar to the existing acceptance/rejection constrained PF method, is proposed to restrict the posterior particles to be generated from the valid prior particles. Third, the validity of state estimation is ensured through adjustment of part of posterior particles according to the posterior density function of states, which is accomplished by deleting uniformly selected violated posterior particle and uniformly selected valid posterior particle for reproduction. Compared with the existing methods, the proposed method implements constraints with better physical interpretation, and involves no numerical optimization procedure and no restrictive assumptions about the distributions. Simulation results demonstrate its effectiveness.

A basic automation system of online hardening in a die steel plant is introduced. It is based on Siemens S7-400 PLC and WinCC. The design of hardware and software is water-oriented due to the fact that a die steel pre hardened is very sensitive to water consumption and ratio. The control of plunger valves, electric valves, roller speed, water pressure and spray distance is adopted to make water be steady and precise. The practice in reality shows the water control meets the design requirements and hardening results are superior quality.

Classification of four-class motor imagery EEG based on CSP-HMM

Nanjing Li Gong Daxue Xuebao/Journal of Nanjing University of Science and technology 2012年第SUPPL.2期36卷 197-201页

作者： Wang, Dong-Yang Jin, Jing Wang, Xing-Yu Key Laboratory of Advanced Control and Optimization for Chemical Processes of Ministry of Education East China University of Science and Technology Shanghai 200237 China

In this paper, a new classification method based on common spatial pattern (CSP) and hidden markov model(HMM)is presented to classify the EEG of four-class motor imagery. 4 s data of motor imagery is selected and four 2 s sub-data sets are obtained by sliding time window with 0.5 s step size. CSP is used to extract features from the four sub-data sets respectively. Features from each class are used to train one HMM. Four different HMMs are obtained corresponding with the four classes. Test data are measured by the four HMMs and classified based on the maximum likelihood obtained from the four HMMs. The results show that HMM yields better performance than Bayesian linear discriminant analysis.

Attribute reduction based on ant colony algorithm for optimization of minimal reductions

Nanjing Li Gong Daxue Xuebao/Journal of Nanjing University of Science and technology 2012年第SUPPL.2期36卷 48-52页

作者： Yin, She-Jie Zhang, Ling-Bo Gu, Xing-Sheng Xu, Zhen-Hao Key Laboratory of Advanced Control and Optimization for Chemical Processes of Ministry of Education East China University of Science and Technology Shanghai 200237 China

Attribute reduction is an important topic of the rough set theory and it's a NP-hard problem to find a minimal reduction. Due to the advantage of ant colony algorithm in solving combinatorial optimization problems, this paper treats attribute reduction as a combinatorial optimization problem, and combines the rough set theory with ant colony algorithm to search the minimal reduction. In accordance with the problems in obtaining many minimal reduction sets of the same length, the paper takes the dependence degree of decision attributes on the non-core attributes to measure the solutions and selects the reduction set which has the maximum dependence degree, so as to find the optimal solution. Experimental results verify the validity of the presented algorithm.

This paper is concerned with the problem of nonfragile H ∞ filtering for discrete-time nonlinear systems in Takagi-Sugeno's form. Additive interval uncertainty which reflects imprecision in filter implementation due to finite word length effects is considered. Based on vertex theory and probabilistic robust approach, deterministic and randomized filtering algorithms are proposed, respectively. Compared with the deterministic algorithm, advantages of the randomized algorithm are mainly two-fold. First, it has acceptable computational complexity, especially for high-dimensional systems. And second, it reduces the design conservatism. An example about diode-tunnel circuit is given to illustrate the effectiveness of the proposed method.

Camera self-calibration based on single rectangle

International Conference on Intelligent control and Information processing (ICICIP)

The main difference between visual servo control and computer vision is the requirement of real-time control, which is often higher for the former. Considering the image-based visual control system, camera is included in the closed loop, so the precision is not sensitive to the error of camera parameters. A camera self-calibration method based on a single rectangle is proposed in the paper according to the fact that visual servo system emphasizes real-time property over accuracy for camera models. The image information of the four rectangular vertexes is obtained by the method based on the corner detection in curvature scale space, according to the geometric relationship constructing constraint equations to calibrate camera intrinsic parameters. The advantages of this method are its linear calculation and simple calibrating procedure, avoiding the complex problems of non-linear optimization. The feasibility of this method is shown through simulation and practicality experiments. Regardless of the lower robustness of the proposed method comparing to traditional calibration methods, it is more adaptable to visual servo control system due to its excellent real-time property.
