The traditional control way of reservoir results in a large number of “abandoned water” during annual flood season, and it is possible that there is not always enough water for reservoir storing to maximal beneficial cubage after flood season. Responding to this case, this paper established the minimum abandoned water optimization model of reservoir based on risk analysis. There are two characters in this model: system has more relevancies and nonlinear. As the optimization model has aforementioned characters, this paper use particle swarm optimization method (PSO) to solve the model. In order to improve the convergence problem of PSO, combines PSO with simulating anneal arithmetic (SAA), that is, using particle swarm-simulating anneal arithmetic (P-S) to deal with the constraints in the model. Apply the model to the North Xing Jia reservoir in Yantai City, Shandong Province as an example. The result shows that it can increase markedly the use of water resources of this reservoir, which is of great use for improving the utilization of surface water resources in the north area of China.

The Wavelet-domain hidden Markov Models (HMMs) can powerfully preserve the image edge information, but it lacks local dependency information. According to the deficiency, a novel image denoising method based HMMs via the self-organizing feature map (SOFM) which exploits spatial local correlation among image neighbouring wavelet coefficients is proposed in this paper. SOFM algorithms is popular for unsupervised learning, data clustering and data visualization, and it can capture persistence properties of wavelet coefficients. Experimental results show that the performance of the proposed method is more practicable and more effective to suppress additive white Gaussian noise and preserve the details of the image.

An adaptive genetic algorithm (AGA) to optimize transmission steel tower by using topology optimization theory is presented. First, topology optimization rule and topology combination approach are presented to build the optimization scheme; then, the binary genetic coding is proposed to describe the size of tower, and the fitness function of AGA is obtained by using the penalty function; finally, the adaptive crossover and mutation operators are proposed and the adaptive genetic algorithm is applied to find the optimization solution. Thus, the global optimization result is acquired, which is more economic than the primary structure. A high-voltage steel tower is analyzed as a numerical example to illustrate the performance of the proposed method. The calculated results demonstrate the proposed AGA and topology optimization method can perfectly optimize the tower structure.

To meet the requirements that sludge should burn and generate electricity cleanly in recycling fluidized bed boiler and the bed temperature must be controlled within a given range, a bed-temperature fuzzy controller was designed based on the operation characteristics of sludge combustion in recycling fluidized bed boiler and with bed temperature being used as the control parameter. Mind Evolutionary Computation was adopted to obtain fuzzy control rules. In order to accelerate the process of search and convergence, artificial operation experiences were used to represent excellent modes in populations. The mode and speed of convergence and variation were controlled through experience and heuristic messages, so that the efficiency of generating fuzzy control rules was improved. The simulation results show that the system has excellent control performance and can secure the stability of main steam pressure and bed temperature while satisfying the loading requirement. It has important reference values for sludge combustion control in recycling fluidized bed boiler.

An Improved Baptista algorithm based on conservative chaotic system is proposed in this paper. During encryption, the initial value of the chaotic system is updated timely. The plaintext is divided into groups at the length of a character. In the standard map, when the integer part of y is equivalent to the value of character’s ASCII code, iteration is selected as the cipher text .And before each iterative process, x has been done a simple transformation. Theoretical analysis and experiment results show that the algorithm has a better sensitivity to initial value and an excellent uniformity of distribution in cipher text. The algorithm has the good performance of simple implementation and reliable safety.

Designers’ style-cognition of product form spans different types of products. Ten groups of adjectives were refined through a Kansei Engineering experiment as the most important perceptual style words relevant to industrial designers’ work. The product images with high identification degree were obtained through a perception experiment on different types of products. The focus group method was employed to research the relationship between styles and design details. The form construction regulations were summarized and the rules base of product form construction based on styles was established. The rules base was applied in the design practices, and the results revealed that it can improve designers' creativities and optimize the details design.

According to the relationship between dissolved gases in transformer oil and transformer fault, a transformer fault diagnosis model and related solving steps are proposed derived from multi-class SVM theory. Based on the concept of feature extraction in pattern recognition, a hierarchical structure is employed to extract the input features closely related to the model of classification, and it has effectively suppressed the interference of redundant information. By comparison of the diagnosis results, the best extracting mode is selected. Besides, the adaptive parameter optimization algorithm has both increased the ¿exibility of parameter selection for SVM and enhanced the convergence speed. The results of the final test reveal that the hierarchical multi-class SVM is of high accuracy and excellent generalization.

A novel method is proposed in this note for exponential stability of cellular neural networks with uncertain and time-varying delay. New delay-dependent exponential stability conditions of cellular neural network with time-varying delay is presented by constructing Lyapunov function and using linear matrix inequality (LMI). The sufficient conditions on exponential stability established in this paper, which are easily verifiable, have a wider adaptive range. Finally, a numerical example is given to demonstrate the effect of the proposed method.
