To forecast the thermal response of LPG( liquefied petroleum gas ) storage tank under the conditions of a non-normal thermal environment is of great practical significance to the evaluation of gas storage and transportation security, especially on disastrous accident prediction. This paper is based on the relationship between conservation of mass and energy conservation to describe the physical model and mathematical model of tank of LPG storage tank thermal response under high-temperature environment. And to have the theoretical analysis on the process from the high temperature environment to the internal heat transfer medium and the confirmation of the system pressure, and use the finite difference method to solve the mathematical model for thermal response of the liquefied gas storage tank, and found the rule of change of the pressure, temperature, density and quality under liquid region and the gas zone. The Object-oriented, visualization of visual c++ software was used to develop the numerical simulation software of the liquefied gas storage tank thermal response under the environment of high-temperature. This software is used to calculate the numerical value of the thermal response and the curve simulation of liquefied petroleum gas storage tank under the different flame environment, the different shape of the container, and the filling of the volume of different media etc.

Opportunistic Spectrum Access (OSA), where cognitive radios opportunistically access spectrum bands currently unused by primary users, can significantly enhance the spectrum utilization. The more channels sensed, the more spectrum opportunities. As such, the more sensing time spent, the less transmission time. Thus, there is a tradeoff between spectrum sensing and data transmission. A natural question that arises then is how many and which channels should be sensed and accessed, respectively, to maximize system throughput. Considering sensing overhead, this paper develops an analytical framework for distributed cooperation based OSA by using Partially Observable Markov Decision Process (POMDP). A suboptimal greedy strategy with reduced complexity yet comparable performance is also developed.

A novel method of feature extraction form protein sequences, structures and physicochemical properties has been proposed and obtained a better classification results by the key eigenvector obtained form knowledge reduction combined with the algorithm of support vector machine. Based on Jackknife detecting methods, the comprehensive classification results 78.3% and 90.9% for all-α,all-β,α+β and α/β have been obtained by the method of support vector machine when we tested Z277 and Z498 in database. Moreover, we found that protein physicochemical properties have a strong influence on classification precision of protein structure with Matlab. These results show that the method of feature extraction based on rough set is effective and available, the research of protein structure for support vector machine classification based on rough set is very effective.

Continuous wavelet transforms of multivariable vector function spaces are discussed. In the weak topology we get the reconstruction formulas of the continuous wavelet transforms of multivariable vector function spaces produced by the integral kernel of the transform multivariable vector functions and those of it produced by the integral kernel of the multivariable vector functions which are different from the transform multivariable vector functions. The relation between the two kinds of the reconstruction formulas is discussed. We get the simplest form of reconstruction formulas.

In recent years, there has been a growing interest in wireless sensor network. In wireless sensor network, constrained energy is one of the most critical problems. In-network data aggregation is essential for the efficient operation of wireless sensor network. In this paper, we propose a novel energy saving topology control algorithm(ESTP). This scheme enable the node within a given distance cooperate with each other sending data selectively and then confused current data with subsequent data to achieve elimination of redundancy between data from continuous time spot. Simulation is conducted to evaluate the performance of this approach in term of system lifetime. Numerical results show that the proposed scheme reduced the amount of data transmission within the node cluster dramatically and thus prolong the network lifetime.

In this paper, a method with tabu search and multi-population based genetic algorithms for path planning is proposed. Different genetic operators are compared in order to find the fittest genetic operator. The simulation indicates that the tabu search heavily enlarges the search efficiency, and multi-population technic combine with different fitness functions can avoid trapping into local optimal solution.

There are many methods for image fusion now. However, Multi-wavelet is attached importance to its superiority on theory and its potential on applications. Lifting scheme is not only a fast algorithm of existing wavelet transforms, but also a tool to produce new wavelet transforms. According to the characteristic of the lifting scheme and multi-wavelet transform, a new lifting scheme for multi-wavelet transforms was presented in this paper, and it was applied to image fusion. Better results were achieved.

Aiming at the defect of traditional Risk Priority Number(RPN) method in FMECA, a RPN assessment method is put forward which bases on the fault propagation probability and cost, then a corrective actions choice method is presented by gray correlation theory. Firstly, the occurrence probability and cost are calculated according to fault propagation tree. RPN is assessed by the overall risk of the events. This method avoids the subjectivity and inaccuracy of O,S and D' ranking assessment in traditional RPN. Then a gray correlation theory is introduced in to implement corrective actions choice for the failure mode whose RPN value is higher than the acceptable risk. The choice method has made up for the lack of corrective actions choice method in traditional RPN. Finally, an aircraft elevator control sub-systems is taken as an example and RPN assessment method and actions choice method above are used, a better result is obtained.
