Background. Previous studies have shown that an external versus the internal focus of attention is an effective and efficient method to improve athleteschr('39') performance under anxious conditions. Objectives. The current study aimed to assess the effect of the practice with a distinct focus of attention on the penalty kicking performance of adolescent soccer players with different expertise...

In this article we study the simplest one-dimensional transport equation ut + aux = f and study the implementation of the boundary condition using a penalty

Constrained optimization problems have a wide range of applications in science, economics, and engineering. In this paper, a neural network model is proposed to solve a class of nonsmooth constrained optimization problems with a nonsmooth convex objective function subject to nonlinear inequality and affine equality constraints. It is a one-layer non-penalty recurrent neural network based on the...
