In this paper, we develop some stationary iterative schemes in block forms for solving double saddle point problem.To this end, we first generalize the Jacobi iterative method and study its convergence under certain condition.Moreover, using a relaxation Lithium Ion Phone Battery parameter, the weighted version of the Jacobi method together with it
The underground mining environment is currently based on technology that uses mainly analogue sensors in machine and equipment control systems.The primary machine performing the most important functions in a mining system is the powered roof support.In order for it to work properly, it is important that it achieves the required power.To ensure this
