We extend the idea of nonlinear multisplitting and consider a new model ill which the iteration is executed asynchronously: Each processor calculate the solution of an individual nonlinear system belong to its nonlinear multisplitting and can update the global approximation residing in the shared memory at any time. A local convergence analysis of this model is presented. Finally, we give a uumerical example which shows a 'strange' property that speedup Sp > p and efficiency Ep > 1.展开更多

文摘Nonlinear multisplitting method is known as parallel iterative methods for solving a large-scale system of nonlinear equations F(x) = 0. We extend the idea of nonlinear multisplitting and consider a new model ill which the iteration is executed asynchronously: Each processor calculate the solution of an individual nonlinear system belong to its nonlinear multisplitting and can update the global approximation residing in the shared memory at any time. A local convergence analysis of this model is presented. Finally, we give a uumerical example which shows a 'strange' property that speedup Sp > p and efficiency Ep > 1.

文摘Since the concept of cooperative consumption was proposed,the sharing economy has become the topic of highest concern in the academic world.From the perspective of the economic market,the sharing economy has created a new model that breaks the original economic order,which can accommodate more labor.Compared with traditional employment methods,the sharing economy has undergone significant changes in terms of labor.The sharing economy is extremely dependent on information technology,and the employment relationship is relatively vague.This poses great challenges to the welfare,income security,and stability of college graduates’employment.This paper explores and analyzes the new employment methods from the perspective of the sharing economy.
文摘Based on shift-share method,this article employs regional share,structural shift and competitive shift to analyze the structural benefit and competitive position of agricultural structure in western China by comparing with agriculture,foresting,stockbreeding and fishing before and after Conversion of Farmland to Forest and Grassland(CFFG) .Then authors draw following conclusion:while CFFG program has been put in practice,the agricultural structure in western China has some typical characteristics,such as growth faster,structural predominance obvious and more competitive.But the contributiveness from the competition is not too much yet,and the structural benefit of forest estate and stockbreeding are restrained.
