This work presents an efficient method based on asymptotic models in order to solve numerically eddy current problems a bi-dimensional setting with high contrast of linear relative magnetic permeability ?r ? 1 between conductor and dielectric subdomain. We describe skin effect by deriving multiscale expansion for the potential power series small parameter ? which represents depth. make explicit...

We consider the mobile service scenario where video programming is broadcast to low-resolution wireless terminals. In such a scenario, broadcasters utilize simultaneous data services and bi-directional communications capabilities of the terminals in order to offer substantially enriched viewing experiences to users by allowing user participation and user tuned content. While users immediately b...

In this paper, a novel algorithm for a car license recognition system is presented. We employ a double back-projection super-resolution image enhancement technique. Modification of initial guess estimation idea has resulted in accuracy improvement and convergence speed up. Bi-lateral back-projection filtering scheme which has been employed as an advanced preprocessor can achieve edge-preserving...

We study the Ginzburg-Landau energy of superconductors with high , put in a prescribed external eld h ex , for h ex varying between the two critical elds H c 1 and H c 2. As ! +1, we give the leading term in the asymptotic expansion of the minimal energy and show that energy minimizers have vortices whose density tends to be uniform and equal to h ex. In this paper, we study minimizers of the G...

Sodium-ion batteries operating at ambient temperature hold great promise for use in grid energy storage owing to their significant cost advantages. However, challenges remain in the development of suitable electrode materials to enable long lifespan and high rate capability. Here we report a sodium super-ionic conductor structured electrode, sodium vanadium titanium phosphate, which delivers a ...

We report results of experimental test the High Temperature Superconductor (HTS) based fast-cycling prototype accelerator magnet capable to operate up about 300 T/s field ramping rate with some 0.5 T B-field in gap. The measured upper limit for cryogenic cooling power required support conductor operation at high rates indicates great potential such type magnets rapid cycling synchrotrons neutri...

In soliton models expressed in terms of the non-linear chiral field, the electric current has an anomalous gauge-field contribution as the baryon current does. We study the spin polarized Skyrmions coupled with the electromagnetic field via the gauged Wess-Zumino term and calculate configurations of the Skyrmion and the gauge field with boundary conditions to ensure the physical charge number f...

We construct N = 4 supersymmetric KdV equation as a hamiltonian flow on the N = 4 SU(2) super Virasoro algebra. The N = 4 KdV superfield, the hamiltonian and the related Poisson structure are concisely formulated in 1D N = 4 harmonic superspace. The most general hamiltonian is shown to necessarily involve SU(2) breaking parameters which are combined in a traceless rank 2 SU(2) tensor. First non...
