A computational model is presented for the simulation of three-dimensional electrodiffusion of ions. Finite volume techniques were used to solve the Poisson-Nernst-Planck equation, and a dual Delaunay-Voronoi mesh was constructed to evaluate fluxes of ions, as well as resulting electric potentials. The algorithm has been validated and applied to a generalized node of Ranvier, where numerical re...

Electric field distribution in high voltage direct current (HVDC) cross-linked polyethylene (XLPE) cable at steady state is researched in this study. Under the condition that no cavity exists, equations describing the critical temperature difference for field reversal, and electric field distribution at steady state are proposed. When the cable with cavity is studied via the finite element anal...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

Material excavation is the primary activity in surface mining operations; and shovel excavators are the primary production equipment in mining industry. The active population of cable shovels is about 2400 units around the world out of which 1700 are 20mt or larger capacity (http://parkerbaymining.com/mining-equipment/ electric-shovels.htm). Joy Global (P&H), Caterpillar (formerly under Bucyrus...

"I'll put a girdle round the earth In forty minutes"? shall be effected by more legitimate and trustworthy, although less immaterial agency. A little before sunrise on the 5th of August, the American termination of the Atlantic telegraph cable was landed in the Bull's Arm inlet of Trinity Bay, Newfoundland, and the deflection of the magnetic needles, attached to the termination of the cable imm...

OBJECTIVE To solve the complicated wires and battery maintenance problems in the application of wearable computing for biomedical monitoring, the electromyography (EMG) measurement system using conductive fabric for power supply and electric shield for noise reduction is proposed. MATERIAL AND METHODS The basic cable-free network system using conductive fabric, named as "TextileNet" is develo...

We study the formation and dynamics of normal domains in Rutherford-type superconducting cables. We use an effective circuit model to account for the electric current redistribution process between the multifilamentary strands in the presence of a normal zone. We obtain and integrate numerically the diffusion equations for the temperature and the current-density distributions in the cable. Our ...

it was important to study the shielded effectiveness to reduce the electromagnetic interference and to protect electronic components. in this paper, the boundary element equation of linear segment was derived from the two-dimension boundary integral equation and linear interpolating function, and the formulas of potential and electric field intensity were also given. To demonstrate the accuracy...
