摘要：
In this paper fuzzy bi-directional associative memory (BAM) neural networks with constant delays are considered. Some sufficient conditions for existence and global exponential stability of unique equilibrium point are established by using fixed point theorem and differential inequality techniques. The results obtained are easily checked to guarantee existence, uniqueness and global exponential stability of equilibrium point.

摘要：
In this paper, we investigate the bifurcations and dynamic behaviour of travelling wave solutions of the Klein–Gordon–Zakharov equations given in Shang et al, Comput. Math. Appl.
56, 1441 (2008). Under different parameter conditions, we obtain some exact explicit parametric representations of travelling wave solutions by using the bifurcation method (Feng et al, Appl. Math. Comput.
189, 271 (2007); Li et al, Appl. Math. Comput.
175, 61 (2006)).

Contourlet Transform;Image Fusion
摘要：
Image Fusion is integrating two or more sensors at the same time or at different times of image or videos equenece to generate a new interpretation of this scene. Its main purpose is increasing reliability or image resolution by redueing uncertainty through redundancy of different images. In this paper, a image fusion method based on contourlet transform is presented. The algorithm can fuse corresponding information in different resolutions and directions, which makes the fused image clearer and more abundant in details. Meanwhile, because of the fuzzy logic's capacity of resolving uncertain problems, it overcomes the drawbacks of traditional fusion algorithm based on contourlet transform, and integrates as much information as possible into the fused image.
摘要：
This paper is devoted to the existence of compressible liquid crystals system in non-smooth domain. We are tempted to prove the convergence of solutions depending on that of corresponding spatial domains for liquid crystals equations of compressible flow. Copyright (c) 2012 John Wiley & Sons, Ltd.

摘要：
The general credit scoring model is to solve the two classification problems, but in real life we often encounter multiple classification problems. This paper proposes a multi-class support vector machine, which can solve multiple classification problems in the behavior assessment model.

We find the greatest value α

$S^{\alpha_{2}}(a,b)A^{1-\alpha_{2}}(a,b)< T(a,b)< S^{\beta_{2}}(a,b)A^{1-\beta_{2}}(a,b)$
hold for all a,b > 0 with a ≠ b. As applications, we get two new bounds for the complete elliptic integral of the second kind in terms of elementary functions. Here, S(a,b) = [(a

$T(a,b)=\frac{2}{\pi}\int\limits_{0}^{{\pi}/{2}}\sqrt{a^2{\cos^2{\theta}}+b^2{\sin^2{\theta}}}{\rm d}\theta$
denote the root-square, arithmetic, and Toader means of two positive numbers a and b, respectively.

摘要：
In this paper, we deal with an inverse source problem of integro-differential parabolic equations, which comes from nonlinear pollution problems in porous media. We study the existence and uniqueness of solutions for the direct problem as well as the existence of quasisolutions of the inverse source problem in an appropriate class of admissible source functions.
摘要：
Let G is a connected graph with vertex set V, then the eccentric connectivity index of G is defined as Σ v∈V(G) deg(v)ecc(v) where deg(v) is the degree of a vertex v and ecc(v) is its eccentricity. The nanostar dendrimer is part of a new group of macromolecules that appear to be photon funnels just like artificial antennas. We obtain exact formulas for calculating the eccentric connectivity index of dendrimer nanostars.
