Current Densities in Density Functional Theory [PDF]

open access: yesPhysical Review A, 2013
It is well known that any given density rho(x)can be realized by a determinantal wave function for N particles. The question addressed here is whether any given density rho(x) and current density j(x) can be simultaneously realized by a (finite kinetic ...

Minimax Current Density Coil Design [PDF]

open access: yesJournal of Physics D: Applied Physics, 2010
'Coil design' is an inverse problem in which arrangements of wire are designed to generate a prescribed magnetic field when energized with electric current. The design of gradient and shim coils for magnetic resonance imaging (MRI) are important examples

Experimental Investigation of the Cubic, Cylindrical, and Pile-shaped Obstacles on the Motion and Control of the Body of Saline Density Current [PDF]

open access: yesمهندسی منابع آب, 2023
Introduction: The use of obstacles in dam reservoirs is considered an effective method for directing sedimentation toward the middle of the reservoir (instead of sedimentation next to the dam wall where the facilities are located).

A discussion on the order of magnitude of corrosion current density in reinforcements of concrete structures and its link with cross-section loss of reinforcement

open access: yesRILEM Technical Letters, 2022
This paper deals with the determination of the corrosion current density in chloride-induced corrosion in reinforced concrete structures. Because the corrosion of steel bars is generally localized, calculations of the densities of corrosion current need

Effects of cylindrical and cubic piles on motion of density currents

open access: yesGrađevinar, 2021
Density current is the motion of a fluid in another fluid of a different density, with frequent negative environmental impacts. According to the deposition problems caused by density currents in the vicinity of dam bodies, attempts are usually made to ...
