In this paper, optimal distributed control of the time-dependent Navier-Stokes equations is considered. The control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. A mixed numerical method involving a quasi-Newton algorithm, a novel calculation of the gradients and an inhomogeneous Navier-Stokes solver, to find the opt...


 The inadequacy of mechanization in the production, processing and storage ginger Nigeria has caused its market price to be among lowest international trade. This study examined selection optimal number impeller speed for an improved slicing machine. research was conducted Department Agricultural Bio-Environmental Engineering at Waziri Umaru Federal Polytechnic Birnin Kebbi during April 2...

Motivated by maximizing spot instances in cloud shared systems, this work, we consider the problem of taking advantage unused resources highly dynamic environments while preserving users’ performance. We introduce an online model for sharing that captures basic properties such as unpredictable demand patterns, very limited feedback from system, and service level agreement (SLA) between users pr...
