Thermal and multi-boiling analysis of a rectangular porous fin: A spectral approach
Nonlinear Engineering, 2022 Fins are commonly utilized to enhance (dissipate) heat in various engineering systems that include heat exchangers. In the present investigation, the impact of multi-boiling and thermo-geometric factors on a convective–radiative rectangular porous fin ...

Ground state and excitation spectra of a strongly correlated lattice by the coupled cluster method [PDF]
, 2012 We apply Coupled Cluster Method to a strongly correlated lattice and develop the Spectral Coupled Cluster equations by finding an approximation to the resolvent operator, that gives the spectral response for an certain class of probe operators.

A new view of nonlinear water waves: the Hilbert spectrum [PDF]
, 1999 We survey the newly developed Hilbert spectral analysis method and its applications to Stokes waves, nonlinear wave evolution processes, the spectral form of the random wave field, and turbulence.

Magnetar Oscillations II: spectral method
, 2011 The seismological dynamics of magnetars is largely determined by a strong hydro-magnetic coupling between the solid crust and the fluid core. In this paper we set up a "spectral" computational framework in which the magnetar's motion is decomposed into a

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background Low‐level tragus stimulation (LLTS) has been shown to significantly reduce atrial fibrillation (AF) burden in patients with paroxysmal AF. P‐wave alternans (PWA) is believed to be generated by the same substrate responsible for AF.

A multi-domain hybrid method for head-on collision of black holes in particle limit
, 2011 A hybrid method is developed based on the spectral and finite-difference methods for solving the inhomogeneous Zerilli equation in time-domain. The developed hybrid method decomposes the domain into the spectral and finite-difference domains.
