Software coordination is central to the construction of large-scale high-performance distributed applications with software services scattered over the decentralized Internet. In this paper, a new mobile-agent-based a...
The authors propose a numerical algorithm for the two-dimensional Navier-Stokes equations written in stream function-vorticity formulation. The total time derivative term is treated with a first order characteristics ...
The performance of task scheduling algorithm in cloud computing determines the performance of the cloud system.This study mainly analyzed the application of the artificial bee colony(ABC)algorithm in the cloud task sc...
We are interested in the design of parallel numerical schemes for linear sys-tems.We give an effective solution to this problem in the following case:the matrix A of the linear system is the product of p nonsingular m...
