Ultrasonic Lamb wave has attracted considerable interest to characterize the human cortical bone. Especially, the nonlinear ultrasonic Lamb wave shows great potential to evaluate the micro-damage of cortical bone. However, the quantitatively analysis about the effect of the bone material mechanical properties on the nonlinear Lamb wave are very limited. In this study, a finite-difference time-domain...
In this paper, we study the existence of positive solutions for a class nonlinear boundary value problem { (Φp(u'))'+ a(t)f(u) = 0, 0 <; t <; 1, u'(0) =u(1) = 0, Φp(s)= |s|p-2s, p>1. We obtain the existence of three positive solutions by using Leggett-Williams fixed-point theorem in a cone. Especially, the nonlinear terms f is allowed to change sign. The conclusions in this paper essentially...
Due to the dynamic and anonymous nature of open environments, it is critically important for agents to identify trustful cooperators which work consistently as they claim. In the e-services and e-commerce communities, trust and reputation systems are applied broadly as one kind of decision support systems, and aim to cope with the consistency problems caused by uncertain trust relationships. However,...
An intelligent decision support system based on MAS for new product development is presented for enhancing the success rate of new product development. The dialogue layer, problem decomposition layer, control layer and problem solving layer in the decision process are studied; corresponding decision support apply modules are built based on the design idea of decision support system with multi-structure...
This paper is mainly conceived according to psychological theory to elicit the conception of emotional energy, and then using the charging process ofRC circuit to simulate the object who receives a stimulus, as well as using the discharging process of RLC circuit to simulate the emotional response course of the object after it absorbs the stimulative energy. Further more, the paper discusses the transfer...
