Abstract: Virtools is a set of integrated 2D graphic images, 3D models, audio, video, and so a variety of file formats, interactive software itself has a wealth of interactive behavior module, 3D games can be created, virtual experiments simulation objects very strong interaction with the display and other three-dimensional product. This paper presents a virtual experiment based on 3D and Virtools technology, which is built with 3D experiments scenes, making 3D animation; with Virtools data processing, interactive control. The experiments show that this method has the authenticity, interactivity, simple and easy to implement features.

Abstract: In this paper, the iterative Retinex algorithm is improved to handle dynamic range compression problems. Based on the analysis of the McCann-Sobel algorithm, the iterative smoothing operation can be interpreted as an asymmetric diffusion. In order to characterized the sharp discontinuities in illumination, an edge-stopping function is introduced into the iterative procedure, which is inspired by anisotropic diffusion. Using the improved illumination estimator, dynamic range of images can be arbitrarily manipulated while suppressing undesirable artifacts. Experiments show that the proposed algorithms outperforms several derivatives for dynamic range compression based on the iterative Retinex.

Abstract: China has built many reservoirs in the Yangtze River. Those reservoirs play an important role in flood control, electricity generation and shipping. But it is difficult to operation reservoir group reasonably because the comprehensive utilization demand. Especially in flood-season, there are usually many different targets to be considered. This paper researched the multiple targets operation of reservoir group in flood-season in the Yangtze River by multi-objective evaluation method. Three reservoir group operation schemes were selected to be compared. The results show that scheme three is the best scheme which has the highest evaluation value. The method this paper proposed is effective in comparing and selecting schemes in flood control management.

Abstract: Using interest management, a lot of irrelevant dada can be reduced during transmission from the publishers to subscribers. This paper proposes to examine this question with the aim of efficiency and scalability of the transmission on how to design a spatial-based approach which combines dynamic quad-tree and sort list, and predicate logic-based approach in large-scale analytic simulation. For analytic simulation of military operation, the interests regions of the spatial entities are formulated as circles or rectangles, and how to predict the entry time and exit time of the regions is studied in detail.

Abstract: the paper made an adjustment on the mortality decomposition model which was first proposed by the author. The mortality data can be processed by the classical wavelet and HHT methods. Compared with the classical mortality analyzing method, more information about longevity risk can be captured by the adjusted mortality decomposition. As a new development, the adjusted mortality decomposition is more effective for the short data set like China. Also the paper gave a modified form of longevity risk index which is different from that the author introduced in another paper. The new modified index is more suitable for China. Based on the adjusted decomposition of mortality rate data and modified longevity risk index, the paper gave their application and detailed analysis on China longevity risk. The important result of different provinces is also given.

Abstract: This paper mainly concerns the uniqueness of solutions for a fourth order boundary value problem. By virtue of Browder theorem, the main result is obtained when the nonlinearity term f satisfies the Lipschitz condition. The result is new and complement of some previously known results.

Abstract: This paper introduces several methods in solving the wave equations for a loudspeaker. The separation of variables method is very common for solving constant coefficient linear partial differential problems. The finite difference method has been the main method of numerical computation in early work. The direct method is to formulate the boundary integral equation and can be solved using a direct time integration procedure. There are also some transform methods such as Fourier, Laplaces and wavelet transforms etc. to solve the wave equations. The retarded potential technique to solve the wave problems numerically was first used in the early 1960s. Since then, many authors have worked on the method and its applications.

Abstract: A quantum-behaved particle swarm optimization algorithm is presented in this paper for solving nonlinear equations. The positions of particle are coded by probability amplitudes of qubits that are updated by quantum rotation gates in this method. The corresponding real number solution at specified interval can be extracted by this algorithm for solving nonlinear equations. Compared to real traditional method, the simulation results show that this algorithm is more accurate and effective.

Abstract: At present, during the process of architecture market management information, it is necessary to use the difference supervision theory, which can improve the efficiency of the supervision, save the supervision resource and reduce the supervision cost. According to the research status of the difference supervision theory, Bayesian inference theory is proposed to verify an engineering registration worker whether an affiliated worker or not. And a example is presented.

Abstract: At present commonly used distribution network loss calculation theory method, the not fully consider load curve changes. Thus, the theory energy loss too small, and the management energy loss too large. On this issue, the article puts forward an improved Newtons method for distribution network theory energy loss calculation. According to the current transformer substation of 24h a distribution network power records, the trend of the model results show that the total distribution network energy loss. The experimental results show that, compared with traditional methods, improved Newtons method to calculate the result more close to the energy loss calculation theory statistical energy loss.
