The hanger is a critical part of arch bridges which decides the security of the bridge. The tension of hanger is the major parameter to evaluate the structural behavior during the health monitoring. Besides, the damper which used for reducing the vibration significantly affects the tension of hanger. The flexural rigidity and damping stiffness should be considered in order to get accurate tension...
In this paper, a dual-resource constrained job shop scheduling problem was studied. According to the information processing mechanism of an immune system in biotic science, a new immune Genetic Algorithm for flexible job shop scheduling through combining immune algorithm with genetic algorithm was proposed. The algorithm can effectively avoid the premature convergence problem caused by the high selective...
In this paper, we investigate convergence of the Euler scheme to a stochastic competitive age-structured population system in Hilbert space, which is influenced by random fluctuations in the environment and interactions between species. By using Burkholder-Davis-Gundy's inequality, Itô's formula and some special inequalities, numerical solutions based on the Euler scheme will converge to the true...
In this paper we propose a new viscosity approximation scheme for computing fixed points of asymptotically nonexpansive mappings in Banach spaces. Strong convergence theorem is established under some certain different control conditions of the viscosity methods for asymptotically nonexpansive mappings, and some recent results are improved and generalized.
In this paper, aiming at the shortcoming of trust region method, we propose an algorithm using negative curvature direction as its searching direction. The convergence of the algorithm is given. Furthermore, combining trust region method and curve-linear searching techniques, using general curve-linear searching direction a trust region algorithm is proposed. We proved its efficiency and feasibility...
To the condition of the complexity of AVS-M transforming quantization all-zero block detection algorithm changes with video content changes, according to the characteristics of adjacent video frame contents have dependence, a adaptive complexity control algorithm for AVSM transforming quantization is proposed. According to reasonable parameter choice, the algorithm can converge to the given computational...
A forecasting model for gas emission based on wavelet neural network is proposed in this paper. In the model, wavelet neutral network (WNN) is applied to the forecasting with gradient descent and amended by validity of iteration training algorithm. Compared with back-propagation neural networks, forecasting of the model has advantages of faster convergence and more accurate. Simulation results have...
In contrast, there exist bullwhip effect in the supply chain of perishable product more easily. We establish a system dynamics model of the supply chain of perishable product, analyzing the causes of the bullwhip effects. Analysis shows that the changes of consumer demand, the differences of retailer's order cycle, wholesaler's order cycle, production cycle, the delivery delay of wholesaler and delivery...
