control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولRobust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملOptimal Shapes in Force Fields
We study a variational problem involving material shapes, modeled as Radon measures on a given ambient space, in a force vector field. We prove some properties of absolutely continuity of the optimal shapes in dependence on the distributions of the zeros of the force field. More regularity properties of the optimal shapes, as well as simple geometrical characterizations, are established in the ...
متن کاملProtein Force Fields
Proteins are arguably the most chemically, structurally, and functionally diverse of the biologically relevant macromolecules. In biological systems, amino acids, the smallest common subunit of proteins, function as intermediates for a variety of biosynthetic pathways, can be diverted for use as sources of energy, and function as neurotransmitters. Polypeptides, containing from two to approxima...
متن کاملPolarizable force fields.
Standard force fields used in biomolecular computing describe electrostatic interactions in terms of fixed, usually atom-centered, charges. Real physical systems, however, polarize substantially when placed in a high-dielectric medium such as water--or even when a strongly charged system approaches a neutral body in the gas phase. Such polarization strongly affects the geometry and energetics o...
