In this paper, the finite-time synchronization of time-delay Hindmarsh-Rose with external disturbance is investigated. Based on Lyapunov stability theory, a scheme is proposed and controllers are constructed to realize it. Finally，numerical simulations are given to verify the theoretical results.

In this paper, we discuss more-for-less paradox in a solid transportation problem. Thereby, we demonstrate a theorem which gives a comfortable condition for the existence of paradox in this type of problem. Next we present an algorithm to find out all the paradoxical pairs as well as paradoxical range of flow and paradoxical pair for a specified flow if paradox exists. Also we illustrate a numerical example in support of the given algorithm.

The performances of most demand-driven anycast routing protocols for wireless sensor networks(WSN) are not good in terms of time delay and energy consumption. For the problem, an anycast routing protocol based on mobile agent for WSN is proposed in this paper. In this protocol, only one-hop neighbor nodes routing information is required by each sensor node, and their monitoring data needs to report to any base station by their cluster-head. Cluster heads search anycast members routing information by mobile agents and establish an anycast routing table. We then present energy consumption model of our protocol. Experiments data show that our protocol has a better performance of energy consumption in a large-scale or a high-density network..

In this paper we have considered simple linear and quadratic equations in Intuitionistic Fuzzy Environment. Here coefficients of the equations are taken as Generalized Triangular Intuitionistic Fuzzy Numbers. We have used the strong and weak solution concept to solve these Intuitionistic Fuzzy Equations. Solution procedures have shown in details.

Based on facts of time delay will influence dynamical behavior and control theory is more appropriate to reflect the natural rule, constructed a predator-prey control model with two delays,choose the two delays as the bifurcation parameter,according to the Routh-Hurwize discriminant method,we studied the local stability and Hopf branch of the control system.The sufficient conditions for the local stability and the existence of Hopf bifurcation are established.Finally,the effectiveness of the controller is verified by numerical simulation.
