Optimal control on surface impedance applied to RCS minimization

Journal of Electromagnetic Waves and Applications, 1996
We develop an optimal control algorithm, using a BI method, in order to obtain the most favourable RAM coating on a given 3D perfectly conducting scatterer, minimizing its monostatic RCS. The RAM is simulated using a first order impedance boundary condition with a scalar surface impedance corresponding to an isotropic passive structure and defined ...

Desanding at the Wellhead for Optimal Well Productivity and Minimal Risks to Surface Facilities

Abu Dhabi International Petroleum Exhibition & Conference, 2016
Abstract Wellhead desanding may increase the productivity of an oil/gas well as it opens the opportunity to a minimized choked-back production. Utilizing a wellhead desanding system upstream of the choke valve, minimizes the risk of erosion of the downstream equipment as for example; valves piping, etc.

Optimization of a railway wheel profile to minimize flange wear and surface fatigue

Wear, 2013
Abstract Damage to wheels and rails due to wear and fatigue affects the safety and maintenance of railway vehicles. The present study optimizes profile of the wheel flange for reducing flange wear and surface fatigue on a curved track. The railway dynamic analysis program VAMPIRE is employed to calculate different loading conditions, contact pressure,

Minimization of the potential energy surface of Lennard–Jones clusters by quantum optimization

Chemical Physics Letters, 2005
Abstract One of the most widely used strategies for global optimization employs the concept of classical simulated annealing. In the last decade an alternative approach has been suggested based on quantum simulated annealing. Here, we apply quantum annealing ideas to finding minimum energy structures of Lennard–Jones clusters.

Design Optimization for Cogging Torque Minimization Using Response Surface Methodology

IEEE Transactions on Magnetics, 2004
This paper discusses the application of response surface methodology (RSM) to design optimization for brushless dc permanent magnet motors for a hard disk driver to reduce cogging torque. The feasibility of using RSM with the finite-element method in practical engineering problems is investigated with computational examples and comparison between the ...

Optimization of Partial Differential Equations for Minimizing the Roughness of Laser Cutting Surfaces

2010
This work introduces a mathematical model for laser cutting which involves two coupled nonlinear partial differential equations. The model will be investigated by linear stability analysis to study the occurence of ripple formations at a cutting surface.
