Concrete guideways for proposed MAGLEV vehicles may be reinforced with electrically conducting and magnetizable steel rebars. Transient magnetic fields due to passing MAGLEV vehicles will then induce transient currents in the rebars leading to power dissipation and temperature rise as well as Lorentz and magnetization forces on the rebars. In order to evaluate if this heating and force on the r...

Integral formulations inhererikly lead to dense systems of equations. For this reason, integral formulations are oftfen thought t,o be computtationally t,oo expensive t,o be considered as a practical approach. To make integral met,hods more appealing effort. must, be devoted to solving large dense linear systems efficiently. There are several factors to be taken into account, when considering a...

We have investigated magnetoresistance properties of (100) epitaxial, (111) textured and polycrystalline spin valve heterostructures on (100) Si substrates by UHV ion beam sputtering at room temperature. Magnetoresistance was measured as a function of Cu interlayer thickness (tl) with 10 A 5 tl 5; 100 A and the maximum was found at 20 A in the case of (100) epitaxial spin valves. Highly (1 11) ...

The objective of this research is to examine the steady incompressible two-dimensional hydromagnetic boundary layer flow nanofluid passing through a stretched sheet in influence viscous and ohmic dissipations. present problem obtained with help an analytical technique called DTM-Pade Approximation. mathematical modeling considered form partial differential equation transformed into suitable sim...

Implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. This clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. Selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...

The equivalent circuit model for artificial magnetic materials based on various arrangements of split rings is generalized by taking into account losses in the substrate or matrix material. It is shown that a modification is needed to the known macroscopic permeability function in order to correctly describe these materials. Depending on the dominating loss mechanism (conductive losses in metal...

For one to be a good power electronics engineer must know lot about lot. Power engineers obviously have conversion circuits and topologies. But, we also basic understanding of semiconductor physics truly understand how our switching devices work make best use them. We deep magnetics devices. all different types capacitor technologies, the characteristics each, where each fits in converter desig...
