Abstract: This paper presents the findings of a study on decision making models for the migrant’s worker group incident emergency management based on Analytic Hierarchic Process (AHP). Analytic Hierarchic Process (AHP) helps to quantitate and layer the complex migrant’s worker incident emergency management problem, the aim of the work is to improve the support for analysis and decision through the importance comparing of various factors associated layer by layer.A case study conduct in Wukan village Shantou city of Guangdong province revealed that AHP model can do effective decision making

Abstract: As a milestone method, the inverse scattering transformation is also known as the nonlinear Fourier transformation for solving nonlinear partial differential equations analytically. The equivalent integral equations play a crucial role for the inverse scattering transformation. In this paper, the equivalent integral equations of the static Schrödinger equation are derived by the variation of constants method. The derivation of the equivalent integral equations provides with a necessary help for the beginners to study the inverse scattering transformation method in soliton theory.

Abstract: In this paper, the exp-function method is improved for constructing exact solutions of nonlinear differential-difference equations with variable coefficients. To illustrate the validity and advantages of the improved method, the mKdV lattice equation with an arbitrary function is considered. As a result, kink-type solutions are obtained which possess rich spatial structures. It is shown that the improved exp-function method can be applied to some other nonlinear differential-difference equations with variable coefficients.

Abstract: By using part of speech information to similarity calculation of paraphrase sentences, the similarity calculation method is improved. The improved method includes multi information of paraphrase text, such as, matching words information and part of speech information. A small-scale comparing experiment of double negation sentence paraphrase for two method of similarity calculation has been done, and the experimental results indicated effect of improvement method.

Abstract: An improved SPH method for water fluid simulation was proposed in this paper. We used higher order splines to improve the stability, and two layers virtual particles to solve particle inconsistency problem near the boundary area. Due to the improvements paid more attention on details, we obtained more realistic and stalbe effect, which was different with previous works. Experimental results showed that our method was realistic, and could achieve real-time frame rate when particle amount was less than 10000.

Abstract: Although theoretical result of convergence for improved generalized ant colony optimization (IGACO) algorithm has been proved in recent years, the convergence speed is also an open and difficult problem. This article, based on the Markov model, tries to explore the analysis of convergence speed for IGACO algorithm. Some experiments have been studied to compare the convergence speed between ant colony optimization (ACO) algorithm and IGACO algorithm.

Abstract: Multi-objective optimization problems are very important, but it is hard to optimized or solved. Generalized ant colony optimization (GACO) algorithm is a new kind of ant colony optimization (ACO) algorithm developed in recent years. In this paper, we try to combine Multi-objective optimization problems with GACO algorithm, established a model for multi-objective GACO algorithm by absorbing state Markov chain, and present a method for estimating the convergence speed of multi-objective GACO algorithm. Simulation results show that the convergence speed of multi-objective GACO algorithm is faster than traditional multi-objective ACO algorithm.

Abstract: This paper puts forward on the Rough Set theory algorithms, and combined it with the method of determining the index weights, then established a weight determined algorithm model based on rough set, Thereby reducing the influence of subjective factors on the weight determination.

Abstract: The Electronic Flight Bag (EFB) provides pilots real-time or existing data by converting the papery documents into electronic books. Consequently the efficiency and the security have been improved, which reduce pilots’ ground communication time and the paperweight. As a key factor of what influences the takeoff process, the takeoff performance undoubtedly has been an essential research task of EFB, while many factors may affect the takeoff performance, such as flap position, anti-ice and the external temperature. By means of interpolation, this paper integrates those factors and gets Maximum Take-off Weight (TOW), Take-off Decision Speed (V1), Take-off Rotation Speed (VR) and Take-off Safety Speed (V2). And then implants the result into the EFB based on the iOS.

Abstract: Data quantization methods for numerical attributes play an extremely important role in handy talents statistics assessment and technology learning because discrete values of attributes are required in most classification methods. In this paper, we present an region analogy-based quantization method for numerical data. It expresses an inner coherence criterion which is thought to be as a new criterion in the ways of quantization. In addition, a heuristic quantization algorithm is proposed to achieve a satisfying quantization result with the aim to improve the performance of inductive learning algorithms. They realize criterion as well as quantifying the true value attributions exactly and reasonably. Strict experiments on UCI reflects data sets express that our supposed algorithm produces a superior quantization scheme that promotes the classification right of inductive learning than emerging quantization algorithms.
