The classification of corank one forced symmetry breaking [PDF]

open access: yes, 2007
Forced-symmetry breaking occurs when a bifurcation equation changes its symmetry when a parameter varies. It is to be contrasted with the phenomena of spontaneous symmetry breaking when the symmetry of the equations are kept constant but the symmetry of

Symmetry Reduced Model Checking for B [PDF]

open access: yes, 2007
Symmetry reduction is a technique that can help alleviate the problem of state space explosion in model checking. The idea is to verify only a subset of states from each class (orbit) of symmetric states.

Symmetry sensitivities of Derivative-of-Gaussian filters [PDF]

open access: yes, 2010
We consider the measurement of image structure using linear filters, in particular derivative-of-Gaussian (DtG) filters, which are an important model of V1 simple cells and widely used in computer vision, and whether such measurements can determine local

On the solutions and conserved vectors for the two-dimensional second extended Calogero-Bogoyavlenskii-Schiff equation

open access: yesResults in Physics, 2021
This paper studies the second extended Calogero-Bogoyavlenskii-Schiff (eCBS) equation in (2+1)–dimensions, which was proposed in the literature a short time ago.

A study of (3+1)-dimensional generalized Korteweg-de Vries- Zakharov-Kuznetsov equation via Lie symmetry approach

open access: yesResults in Physics, 2020
In this work, we analytically examine a (3+1)-dimensional generalized Korteweg-de Vries-Zakharov-Kuznetsov equation (gKdV-ZKe). Solutions of this equation, including a non-topological soliton, are obtained by Lie symmetry reductions and direct ...

On the solutions and conservation laws of the 2D breaking soliton equation of fluid mechanics

open access: yesPartial Differential Equations in Applied Mathematics, 2021
In this article, we study two-dimensional generalized breaking soliton equation, which describes two-dimensional interchange of Riemann wave disseminating alongside y-axis with a long wave disseminating alongside x-axis. We derive Lie symmetry generators

Conditional symmetry model as a better alternative to Symmetry Model for rater agreement measure [PDF]

open access: yes, 2004
In almost all life or social science researches, subjects are classified into categories by raters, interviewers or observers. Many approaches have been proposed by various authors for analyzing the data or the results obtained from these raters ...
