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

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 ...

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

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

Structured Distance to Normality of Dirichlet–Neumann Tridiagonal Toeplitz Matrices

open access: yesAxioms
This paper conducts a rigorous study on the spectral properties and operator-space distances of perturbed Dirichlet–Neumann tridiagonal (PDNT) Toeplitz matrices, with emphasis on their asymptotic behaviors. We establish explicit closed-form solutions for

The Topological Entropy Conjecture

open access: yesMathematics, 2021
For a compact Hausdorff space X, let J be the ordered set associated with the set of all finite open covers of X such that there exists nJ, where nJ is the dimension of X associated with ∂. Therefore, we have Hˇp(X;Z), where 0≤p≤n=nJ.
