In this chapter, we propose a stable and efficient algorithm for animating cloth-like materials using mass-spring systems. An integration scheme derived from implicit integration allows us to obtain interactive realistic animation of any mass-spring network. We alleviate the need to solve a linear system through the use of a predictor-corrector approach: We first compute a rapid approximation o...

In this article, a coupled computational framework is presented for the numerical simulation of mass transfer under the effects of natural convection phenomena in a field contains water-copper Nano-fluid. This CFD model is build up based on accurate algorithms for spatial derivatives and time integration. The spatial derivatives have been calculated using first order upwind and second order cen...

A lot of articles dedicated to NLO QCD corrections to polarized DIS have been published. Calculations in most of them are performed in an assumption that the quark mass is equal to zero (see [1, 2, 3, 4, 5, 6, 7] and review [8]). However there are some works when authors estimate a finite quark mass effect for both unpolarized [9] and polarized structure functions [10, 11, 12, 13, 14, 15, 16]. ...

BACKGROUND AND AIMS Grazing is a complex process involving the simultaneous occurrence of both trampling and defoliation. Clonal plants are a common feature of heavily grazed ecosystems where large herbivores inflict the simultaneous pressures of trampling and defoliation on the vegetation. We test the hypothesis that physiological integration (resource sharing between interconnected ramets) ma...
