The paper is devoted to study a mesh-free analysis method of structural elements of engineering structures based on B-spline Wavelet Basis Function. First, by employing the moving-least square method and the weighted residual method to solve the structural displacement field, the control equations and the stiffness equations are obtained. And then constructs the displacement field of the structure by using the m-order B-spline wavelet basis function as a weight function. In the end, the paper selects the plane beam structure and the structure with opening hole to carry out numerical analysis of deformation and stress. The Finite Element Method calculation results are compared with the results of the method proposed, and the calculation results of the relative error norm is compared with Gauss weight function as weight function. Therefore, the clarification verified the validity and accuracy of the proposed method. Copyright © 2016 Techno-Press, Ltd. Source

In this paper, we study the travel mode choice of residents to determine the set of factors which can influence travel mode choice of residents and analyze the influence factor characteristics. Using Bayesian theory, we analyze the travel decision-making data of the residents, discrete them, and use them in Bayesian network structure learning and parameter estimation by K2 algorithm. We establish a Bayesian network simulation model to analyze the dependence probability relationship between the parent nodes and child nodes. Validation test was carried out for the building simulation model of Bayesian network. Data analysis results showed that the Bayesian network has a high accuracy prediction for actual travel mode choice of residents. This paper studies the Bayesian structure and parameters learning method for the actual travel behavior, and this method which provides a new method for studying the travel mode choice of residents can reveal the relationship between the various attributes associated with travel mode choice through a new perspective. © Ruijing Chen.

The aim of this paper is to develop a new methodology for solving bimatrix games with payoffs of triangular intuitionistic fuzzy numbers (TIFNs), which are called TIFN bimatrix games for short. In this methodology, we define the concepts of the value-index and ambiguity-index and hereby develop a difference-index based ranking method, which is proven to be a total order. The parameterized bilinear programming models are derived from a pair of auxiliary TIFN mathematical programming models, which are used to determine solutions of TIFN bimatrix games. Validity and applicability of the models and method proposed in this paper are illustrated with a practical example. © 2016 - IOS Press and the authors. Source

Aiming at the current problems that the existing bridge structure reliability analysis model is solved slowly and it is difficult to find the global optimal solution and other issues. This paper put forward a kind of reliability analysis model of bridge structure based on improved simulated annealing algorithm, reduced the computational complexity of the inner loop to optimize the disturbance mode, used adaptive cooling control strategy to improve annealing process speed, used the effective offset to improve the solving way. Simulation results showed that the reliability analysis model of bridge structure this paper proposed which based on improved simulated annealing algorithm had better performance, and had certain feasibility and accuracy. © 2014 CAFET-INNOVA TECHNICAL SOCIETY.

A hot-processing map and TEM images of a 1235 aluminum alloy have been used while studying hot-deformation characteristics of this alloy. The results showed that an ideal processing region exists in the high-temperature/low-strain-ratearea and that the power-dissipation efficiency is around 46 %. It is better to avoid deformations at the low-temperature/high-strain rate and the high-temperature/moderate-strain rate due to their processing instability and lower power-dissipation efficiency.
