Consistency in Positive Reciprocal Matrices: An Improvement in Measurement Methods

open access: yesIEEE Access, 2018
Consistency estimation of decision-makers' judgments in decision-making processes is fundamental to generating agreements and making decisions. Analytic hierarchy process (AHP) is a widely used method to solve this type of problem, enabling evaluation of

A non-Hermitian $PT-$symmetric Bose-Hubbard model: eigenvalue rings from unfolding higher-order exceptional points [PDF]

open access: yes, 2008
We study a non-Hermitian $PT-$symmetric generalization of an $N$-particle, two-mode Bose-Hubbard system, modeling for example a Bose-Einstein condensate in a double well potential coupled to a continuum via a sink in one of the wells and a source in the ...

Vortex-induced vibration of two elastically connected bodies: experimental verification of lock-in to multiple eigenmodes

open access: yesJournal of Fluid Science and Technology, 2017
This study examines experimentally the vortex-induced vibration (VIV) of a mechanical system with two eigenmodes. A previous experiment setup was refined to enable the experiment, and was placed in a circulating water channel to submerge a movable ...

Greedy algorithms for high-dimensional eigenvalue problems [PDF]

open access: yes, 2013
In this article, we present two new greedy algorithms for the computation of the lowest eigenvalue (and an associated eigenvector) of a high-dimensional eigenvalue problem, and prove some convergence results for these algorithms and their orthogonalized ...

Estrada Index and Laplacian Estrada Index of Random Interdependent Graphs

open access: yesMathematics, 2020
Let G be a simple graph of order n. The Estrada index and Laplacian Estrada index of G are defined by E E ( G ) = ∑ i = 1 n e λ i ( A ( G ) ) and L E E ( G ) = ∑ i = 1 n e λ i ( L ( G ) ) , where { λ i

A spectral projection method for transmission eigenvalues

open access: yes, 2016
In this paper, we consider a nonlinear integral eigenvalue problem, which is a reformulation of the transmission eigenvalue problem arising in the inverse scattering theory.

On solving the second boundary value problem for the Viscous Transonic Equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
In a rectangular domain, the second boundary value problem for the Viscous Transonic Equation is considered. The uniqueness of the solution to the problem is proved using the energy integral method. The existence of a solution is proved by the method of
