Flux penetration and a.c. losses in type II superconductors: I. Model calculations [PDF]

, 1981
A numerical method is presented which allows the calculation of the a.c. response of type II superconductors under quasi-static conditions for arbitrary jc (B,x), Ben (Ba) and Bex (Ba) relations.

Thermalization from gauge/gravity duality: Evolution of singularities in unequal time correlators

, 2012
We consider a gauge/gravity dual model of thermalization which consists of a collapsing thin matter shell in asymptotically Anti-de Sitter space. A central aspect of our model is to consider a shell moving at finite velocity as determined by its equation

Geometrical enhancement of the electric field: Application of fractional calculus in nanoplasmonics

, 2011
We developed an analytical approach, for a wave propagation in metal-dielectric nanostructures in the quasi-static limit. This consideration establishes a link between fractional geometry of the nanostructure and fractional integro-differentiation.

A generalized asymptotic extraction solution for antennas in multilayered spherical media [PDF]

, 2010
An efficient model is developed to accelerate the convergence of the dyadic Green's function's (DGF) infinite summation when the source and observation points are placed in different layers of a dielectric sphere, thereby expediting computational ...

Research on Quasi-Static Transmission Error Measurement of Spur Gears Based on the Acceleration Method

Machines
Transmission error (TE) is an important parameter in gear dynamics that has a direct impact on the vibration and noise of gears. Under quasi-static conditions, gear elastic deformation and assembly errors amplify with increasing load, potentially ...
