Optimization of three- and four-element lens systems by minimizing the caustic surfaces

Applied Optics, 1990
For an imaging optical system it is, in general, desirable to transform a collection of point sources of light into point images distributed over the focal plane with the appropriate magnification. In practice, this is achieved by varying the lens system parameters such that the spread of a bundle of rays from each object point over the image plane has

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 ...

Sandwich panel design and performance optimization based on triply periodic minimal surfaces

Computer-Aided Design, 2019
Abstract Sandwich panel is a promising engineering structure, attracting more and more research attention. Most of current sandwich panels are constructed with plane skins and lattice cores via traditional fabrication processes. In this work, the skin faces of sandwich panels are designed by the freeform T-spline surfaces. The triply periodic minimal

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.
