for non-darcy flow in submerged porous media a one- dimensional mathematical model has been developed. rockfill detention dams are one of these porous media that comprised of relatively homogenous coarse rockfill which can be used to reduce flood discharge and hydrograph peak. in this research the focus was on the rockfill detention dams in submerged condition. the existence of overtopping rock...

a comprehensive study of schottky barrier mosfet (sbmosfet) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within non-equilibrium green's function formalism. quantum confinement increases the effective schottky barrier height (sbh). (100) orientation provides lower effective schottky barrier height in comparison ...

The collective and purely relaxational dynamics of quantum many-body systems after a quench at temperature $T=0$, from disordered state to various phases is studied through the exact solution Langevin equation spherical $O(n)$-model in limit $n\to\infty$. stationary shown be non-equilibrium state. for $n\to\infty$ are same dynamical universality class. long-time behaviour single-time two-time c...

This paper presents a tractable model of non-linear dynamics market returns using Langevin approach. Due to non-linearity an interaction potential, the admits regimes both small and large return fluctuations. are mapped onto equivalent quantum mechanical (QM) system. Borrowing ideas from supersymmetric mechanics (SUSY QM), parameterized ground state wave function (WF) this QM system is used as ...

Design and analysis of distillation columns usually takes place by using rigorous equilibrium models, where efficiencies are utilized to enhance the designs obtained and have a better approach to the real performance of the column. A second alternative, based on the mass and heat transfer rates, has been proposed and it is known as the non-equilibrium (or rate-based) model. By employing this ap...
