The first one is the one-dimensional particle-in-a-box problem. This turns out to be an excellent conceptual model for conjugated dye molecules (see Chapter 21) and also a model for trapped charged particles. The problem and its solutions are similar to the vibrating string just discussed. ...
Particle in a Box 来自 Semantic Scholar 喜欢 0 阅读量: 177 作者: H Li 摘要: The particle in a box (or the infinite potential well) is a simple idealized system that is completely solved within quantun mechanics. The infinite potential well is a finite sized region in space (the box...
Particle in a Box This simple example of quantum behavior is also often referred to as the ‘standing wave’. Although having no direct counterpart in the physical world, the solutions are related to real problems such as a violin string (or any stringed instrument), an electron in a ...
Moreover, a colloid can assume the form of a rigid particle, a liquid drop, a gas bubble, or a porous particle in the sense that liquid can pass through it. 1.1.2 Colloidal Suspensions: Aqueous Electrolyte Solution and Others In practice colloids are normally present in a suspension form,...
A discrete Fourier series method was derived and used for reformulation of black-box objective functions as continuous functions. Particle swarm optimization (PSO) was then applied to locate the global optimal solutions of the continuous functions derived. The continuous functions generated by the ...
The proposed algorithm is applied to some well-known benchmarks. The relative experimental results show that the algorithm achieves better solutions and faster convergence. 展开 关键词: particle swarm optimiser PSO velocity-free swarm's centroid convergence analysis of algorithm ...
Whereas self-propelled hard discs undergo motility-induced phase separation, self-propelled rods exhibit a variety of nonequilibrium phenomena, including clustering, collective motion, and spatio-temporal chaos. In this work, we present a theoretical fra
THREE DIMENSIONAL ASSEMBLY OF DIAMAGNETIC MATERIALS USING MAGNETIC LEVITATION The ability to assemble three-dimensional structures using diamagnetic particles suspended in solutions containing paramagnetic cations is described. The m... GM Whitesids,F Iievski,A Ellerbee,... 被引量: 0发表: 2014年 ...
The particle swarm optimization (PSO) algorithm represents a new approach to optimization problems in electromagnetics. Based upon a mathematical model of the social interactions of swarms, the algorithm has been shown to be effective at finding good solutions to a number of complicated EM design pro...
Colloidal particles suspended in liquid crystals can exhibit various effective anisotropic interactions that can be tuned and utilized in self-assembly processes. We simulate a two-dimensional system of hard disks suspended in a solution of dense hard needles as a model system for colloids suspended ...
