in this paper, we propose the chebyshev wavelet approximation for the numerical solution of a class of integro-differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields. we show that the chebyshev approximation transform an integral equation to an explicit system of linear algebraic equations. illustrative examples are included t...

Both single emitters and large area field (LAFEs) are generally characterized using the slope intercept of a Murphy–Good (or Fowler–Nordheim) plot, which used to extract enhancement factor emission area. Using shielding model that has been developed recently for LAFE, validity underlying assumption is investigated. It found in case contributions from as well rate at effective number superemitte...

Braneworld scenarios appear in dynamical string tension theories, where is positive between two surfaces separated by a short distance and at the themselves tensions become infinite, therefore producing an effective confinement of strings all matter gravity to space these surfaces. The specific model studied context modified measure formulation as additional degree freedom are not universal, bu...
