Multiple Solutions for Slip Effects on Dissipative Magneto-Nanofluid Transport Phenomena in Porous Media: Stability Analysis [PDF]
Journal of Applied and Computational Mechanics, 2020 In the present paper, a numerical investigation of transport phenomena is considered in electrically-conducting nanofluid flow within a porous bed utilizing Buongiorno’s transport model and Runge-Kutta-Fehlberg fourth-fifth order method.

Jordanian Journal of Computers and Information Technology, 2020 An accurate method for estimating the direction-of-arrival (DOA) jointly with the frequencies of an unknown number of source signals is proposed using the Eigen-approach. Using the minimum eigenvalues of the autocorrelation matrices produces both the DOA

On spectra of quadratic operator pencils with rank one gyroscopic linear part [PDF]
Opuscula Mathematica, 2018 The spectrum of a selfadjoint quadratic operator pencil of the form \(\lambda^2M-\lambda G-A\) is investigated where \(M\geq 0\), \(G\geq 0\) are bounded operators and \(A\) is selfadjoint bounded below is investigated.

The variability of grain yield, seed morphometric and vigour traits of early maturing hybrid maize [PDF]
Journal of Agricultural Sciences (Belgrade), 2021 Breeding for yield and quality requires the assessment of the seed metrics and vigour traits. This study, therefore, assessed the variability and interdependence of grain yield (GY), seed morphometric and vigour traits in hybrid maize.

The Effect of a Linear Tuning between the Antigenic Stimulations of CD4+ T Cells and CD4+ Tregs
Mathematics, 2020 We study the equilibria of an Ordinary Differencial Equation (ODE) system where CD4 + effector or helper T cells and Regulatory T cells (Tregs) are present. T cells trigger an immune response in the presence of their specific antigen.

A class of dissipative differential operators of order three
AIMS Mathematics, 2021 In this paper we find a class of boundary conditions which determine dissipative differential operators of order three and prove that these operators have no real eigenvalues.

Eigenvalues of fourth-order boundary value problems with distributional potentials
AIMS Mathematics, 2022 This paper aims to investigate the fourth-order boundary value problems with distributional potentials. We first prove that the operators associated with the problems are self-adjoint and the corresponding eigenvalues are real.

Stochastic differential equations for random matrices processes in the nonlinear framework [PDF]
Opuscula Mathematica, 2018 In this paper, we investigate the processes of eigenvalues and eigenvectors of a symmetric matrix valued process \(X_{t}\), where \(X_{t}\) is the solution of a general SDE driven by a \(G\)-Brownian motion matrix.

A New Fixed Point Result of Perov Type and Its Application to a Semilinear Operator System
Mathematics, 2019 In this paper, we present a new generalization of the Perov fixed point theorem on vector-valued metric space. Moreover, to show the significance of our result, we present both a nontrivial comparative example and an application to a kind of semilinear ...
