In this article, a parallel computer program is implemented, based on Finite Element Method, to speed up the analysis of hollow circular cylinders, made from Functionally Graded Materials (FGMs). FGMs are inhomogeneous materials, which their composition gradually varies over volume. In parallel processing, an algorithm is first divided to independent tasks, which may use individual or shared da...

Abstract. Two main performance features of high-bandwidth switches are stability and delay. This paper investigates these performance features for input buffered switch architectures that deploy maximal weight matching algorithms to determine the configurations of the switching core. For this purpose, a novel mathematical model of the dynamics of a maximal weight matching algorithm is developed...

We studied the dynamics of synchronization in asymmetrically coupled neural oscillators with time delay. Stability analysis revealed that symmetric excitatory coupling results in synchrony at multiple phase relations. Asymmetry yields two saddle-node bifurcations of the stable states when coupling is asymmetric. By contrast, with inhibitory coupling only in phase or antiphase is stable as long ...

Symmetrically coupled oscillators represent a limiting case for studying the dynamics of natural systems. Therefore, we here investigate the effect of coupling asymmetry on delay-induced oscillation death (OD) in coupled nonlinear oscillators. It is found that the asymmetrical coupling substantially enlarges the domain of the OD island in the parameter space. Specifically, when the intensity of...

background: the purpose of this study was to compare patient delay, diagnosis delay and treatment delay in breast cancer patients of selected public and private health centers in tehran, iran. methods: in this cross-sectional study, female patients with newly diagnosed breast cancer in a public medical complex and a private breast clinic within one year were included. patient delay was consider...

In this article, we propose a macroscopic model for studying routing on networks shared between human-driven and autonomous vehicles that captures the effects of forming platoons. We use to study inefficiency due selfish bound price anarchy (PoA), maximum ratio total delay experienced by users minimum possible delay. To do so, establish two road capacity models, each corresponding an assumption...

In this paper, we present techniques for mitigating the Negative Bias Temperature Instability (NBTI) effect on extensible processors. Firstly, the effect of NBTI on the extended instruction set architecture and the arithmetic logic unit of extensible processors is studied. The study includes modeling the circuit delay increase due to the NBTI and analyzing its impact on the processor lifetime. ...
