In order to improve the quickness and accuracy in big data processing, a processing model of multi objective genetic algorithm based on static Bayesian game in cloud computing is proposed in this paper. Based on analyzing the static Bayesian game model, we proposed a novel multi-objective genetic algorithm optimization. After different difficult tests problems, the proposed SBG-MOGA was able to maintain a better distribution than NSGA-II, and is approximate to NSGA-II in convergence in the obtained no dominated front.

In order to improve the performance of dynamic resource distributing, a estimation of distributed algorithm is researched in this paper. NB-COIN, which is use incremental negative learning with node histogram based, could find the set of most profitable orders in overtime period. While the others algorithm suggested that the working in overtime period is unnecessary, their sets of most profitable orders are only found in normal working time period. The modified model with the proposed algorithm is remarkable in both solution quality and solving efficiency. Copyright © 2016 American Scientific Publishers All rights reserved.

The purpose of this paper is to study on the solution of differential equations based on the new chaotic dynamical system. The new three-dimensional chaotic system is proposed, which relies on a nonlinear exponential term and a nonlinear quadratic cross term necessary for folding trajectories. Basic dynamical characteristics of the new system are analyzed. Compared with the Chen system, the equilibrium points of the new system does not contain the origin, and has a greater positive Lyapunov index can produce more complex shaped chaotic attractor.

Aiming at solving the problem of mass scheduling in the single machine task planning, a time dependent scheduling method is studied in this paper. We study some inverse problems of scheduling. Firstly, we study two inverse scheduling problems on identical parallel machines: the inverse scheduling problem of the total weighted completion time problem with unit processing time on identical parallel machines; the inverse scheduling problem of the total completion time objective on identical parallel machines. We have presented the necessary and sufficient conditions for optimality of the maximum tardiness problem on single machines; also have given the mathematical formulations of the inverse scheduling and method of solving this inverse scheduling problem. For some special cases of the inverse scheduling problems, we have obtained the formulations for the optimal solutions. The experiment result shows it can improve the performance substantially.

Federated identity management technology has been used by more and more users, which supports cross-domain work and supplies single sign-on capability when accessing network service. However, as common users cannot understand server certificate, which makes spoofing attack more likely. This paper proposes one joint identity management bi-direction authentication protocol based on server, with human perceptual authentication code being adopted to verify identity authority server in TLS conversation. The purpose of bi-directional protection of token is reached through binding client certificate and strengthening same original policy. Finally, we analyze the safety with formalized model and prove that protocol can provide safe authentication. © 2016, UK Simulation Society. All rights reserved.

True stress-strain data of 3Cr20Ni10W2 alloy at elevated temperatures were obtained through isothermal compression experiment. By the diverse linear regression for hyperbolic sine equation in Arrhenius type, deformation activation energy Q, materials constants n, α and A under different deforming conditions were calculated. And then the constitutive equation of the 3Cr20Ni10W2 alloy for description of the relationships among flow stress, strain, strain rate and temperature were constructed. The results show that the flow stress predicated by the proposed model agrees well with the experimental results, and the maximum relative tolerance is only 7.45% and correlation coefficient is 0.995.

This paper presents a novel approach using adaptive artificial neural network based model and neuro-controller for online cell State of Charge (SOC) determination. Taking cell SOC as model's predictive control input unit, radial basis function neural network, which can adjust its structure to prediction error with recursive least square algorithm, is used to simulate battery system. Besides that, neuro-controller based on Back-Propagation Neural Network (BPNN) and modified PID controller is used to decide the control input of battery system, i.e., cell SOC. Finally this algorithm is applied for the SOC determination of lead-acid batteries, and results of lab tests on physical cells, compared with model prediction, are presented. Results show that the ANN based battery system model adaptively simulates battery system with great accuracy, and the predicted SOC simultaneously converges to the real value quickly within the error of ±1 as time goes on. © 2009 Elsevier Ltd.

the pedal is one of the most important parts assuring the safety and comfort of automotive. This paper adopts FEM (Finite Element Method) analysis the brake pedal assembly according to the industry standard. In order to obtain the strength of the brake pedal and on the base of the strength result of FEM the fatigue analysis is carried out to verify the strength whether meet the industry standard. At last, some experiments are conducted on the product designed by this method and the experimental results show that no fatigue failure happens. © 2011 IEEE.

Accurate prediction of cell SOC (state of charge) is important for the safety and functional capabilities of the battery energy storage application system. This paper presents a hybrid UPF (unscented particle filter) based SOC determination combined model for batteries. To simulate the entire dynamic electrical characteristics of batteries, a novel combined state space model, which takes current as a control input and let SOC and two constructed parameters as state variables, is advanced to represent cell behavior. Besides that, an improved UPF method is used to evaluate cell SOC. Taking lead-acid batteries for example, we apply the established model for test. Results show that the evolved combined state space cell model simulates battery dynamics robustly with high accuracy and the prediction value based on the improved UPF method converges to the real SOC very quickly within the error of±2%. © 2014 Elsevier Ltd.
