The use of positive and negative penalty functions in solving constrained optimization problems and partial differential equations [PDF]
, 2009 The Rayleigh-Ritz Method together with the Penalty Function Method is used to investigate the use of different types of penalty parameters. The use of artificial springs as penalty parameters is a very well established procedure to model constraints in ...

The Rayleigh-Ritz method still competitive [PDF]
, 1994 An extended Rayleigh-Ritz method for computing two-sided eigenvalue bounds of the one-dimensional Schrödinger equation is presented. The method is based on the B-spline approximation over the truncated domain.

Gradient‐ and Newton‐Based Unit Vector Extremum Seeking Control
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This paper proposes new methods for stable and efficient convergence in multivariable extremum seeking control (ESC) using sliding mode techniques. Inspired by classical sliding modes and finite‐time control, the approach integrates these ideas into gradient‐ and Newton‐based ESC schemes with sinusoidal perturbations.

Buckling Analysis of Functionally Graded Tapered Microbeams via Rayleigh–Ritz Method
Mathematics, 2022 In the present study, the buckling problem of nonhomogeneous microbeams with a variable cross-section is analyzed. The microcolumn considered in this study is made of functionally graded materials in the longitudinal direction and the cross-section of ...

Quantum Spectral Clustering Framework via Compact Circuit Structures
Advanced Quantum Technologies, Volume 9, Issue 10, October 2026.Can a quantum computer cluster data without ever reading the full kernel? This work shows that compact, parameterized circuits estimate the Laplacian quadratic forms directly and perform clustering, without explicitly constructing the full quantum fidelity‐kernel matrix.

Comments on the historical bases of the Rayleigh and Ritz methods
, 2009 In a recent article entitled “The historical bases of the Rayleigh and Ritz methods”, Professor Leissa raised the issue of using two different names, “The Rayleigh-Ritz Method” and “The Ritz Method” for the same procedure.

Free vibration of arbitrary-shaped laminated triangular thin plates with elastic boundary conditions
Results in Physics, 2018 This paper studies the free vibration of arbitrary shaped laminated triangular thin plates based on a modified Fourier series method. An arbitrary shaped triangular plate is mapped into a right-angled isosceles triangular plate with unit length by the ...
