This paper presents an efficient integral-equation (IE) technique for analysis of thick irises inside multilayered rectangular waveguides. The IEs remain the same as in the case of zero-thickness iris and the thickness is accounted for only as a correction ...
We prove in this paper that the equation Δpu+h=0 on a p- hyperbolic manifold M has a solution with p-integrable gradient for any bounded measurable function h:M→R with compact support. ...
Results on isothermal stratification of ice particles in ice slurry storage tanks are presented. Furthermore - in an extension - the melting of ice particles by heat fluxes across the boundaries of storage vessels is also taken into consideration. A conser ...
In the scope of the study of low-frequency electrostatic microinstabilities in tokamak plasmas, attention has been focused on the effect of trapped ions. The ballooning transform has been applied to the gyrokinetic equation, for the case of a large aspect ...
We present some results on coupling Navier-Stokes with shallow water equations for surface flows, and with Darcy's equation for groundwater flows. We discuss suitable interface conditions and show the well-posedness of the coupled problem in the case of a ...
A review. On page 723, the equation should read: M + zH+.bul.: [M + zH]Z+ + e -> M + zH+.bul. (+6 eV) -> M + (z - 1)H+ + H.* -> fragments. [on SciFinder (R)] ...
A recent approach to solve Richards' equation was further improved. This approach brings understanding into the physical processes of infiltration and pending. In particular we apply it to analyze the standard hydrologic tool of Time Compression Approximat ...
Mixed confined and unconfined groundwater flow occurs in a bounded initially dry aquifer when the hydraulic head at the side boundary suddenly rises above the elevation of the aquifer’s top boundary. The flow problem as modelled by the Boussinesq equation ...
This article the resolution of a boundary controlled nonlinear partial differential equation with Volterra series. The generalized Burger's equation which is investigated, accounts for the dominant effects of the acoustic propagation in cylindrical ducts i ...
We investigate analytically, numerically, and experimentally the modulational instability in a layered, cubically nonlinear (Kerr) optical medium that consists of alternating layers of glass and air. We model this setting using a nonlinear Schrödinger (NLS ...
