Effective interactions and large-scale diagonalization for quantum dots
, 2007 The widely used large-scale diagonalization method using harmonic oscillator basis functions (an instance of the Rayleigh-Ritz method, also called a spectral method, configuration-interaction method, or ``exact diagonalization'' method) is systematically

Free Vibration Analysis of Cylindrical Shell from Fiberglass with Navier Boundary Conditions
Механика машин, механизмов и материалов, 2011 The analytical solution of approximate natural frequencies for the free vibration of cylindrical shells of GFRP (glass fiber reinforced plastic) with Navier boundary conditions is presented using the Rayleigh-Ritz method, while the winding angle varies ...

A robust and efficient implementation of LOBPCG
, 2018 Locally Optimal Block Preconditioned Conjugate Gradient (LOBPCG) is widely used to compute eigenvalues of large sparse symmetric matrices. The algorithm can suffer from numerical instability if it is not implemented with care.

Variational description of the positive column with two-stem ionization [PDF]
The ionization balance in diffusion dominated discharges which depends on both one and two step ionization processes is considered. The Spenke diffusion equation (D sq delta n + neutrino n + sq kn =0) describing such conditions is solved by the Rayleigh ...

Compressible seal flow analysis using the finite element method with Galerkin solution technique [PDF]
High pressure gas sealing involves not only balancing the viscous force with the pressure gradient force but also accounting for fluid inertia--especially for choked flow.
