Numerical Study of Three-dimensional Boundary-layer Flow over a Wedge: Magnetic Field Analysis [PDF]
Journal of Applied and Computational Mechanics, 2022 The magnetohydrodynamic flow of a viscous fluid over a constant wedge in three- dimensional boundary-layer has been analyzed both numerically and asymptotically. The magnetic field is applied normal to the flow.

Heterogeneous Diffusion and Nonlinear Advection in a One-Dimensional Fisher-KPP Problem
Entropy, 2022 The goal of this study is to provide an analysis of a Fisher-KPP non-linear reaction problem with a higher-order diffusion and a non-linear advection. We study the existence and uniqueness of solutions together with asymptotic solutions and positivity ...

Heterogeneous Diffusion, Stability Analysis, and Solution Profiles for a MHD Darcy–Forchheimer Model
Mathematics, 2021 In the presented analysis, a heterogeneous diffusion is introduced to a magnetohydrodynamics (MHD) Darcy–Forchheimer flow, leading to an extended Darcy–Forchheimer model.

Asymptotic Bound for RSA Variant with Three Decryption Exponents
Journal of Mathematical Sciences and Modelling, 2023 This paper presents a cryptanalysis attack on the RSA variant with modulus $N=p^rq$ for $r\geq 2$ with three public and private exponents $(e_1,d_1),$ $(e_2,d_2),$ $(e_3,d_3)$ sharing the same modulus $N$ where $p$ and $q$ are consider to prime having ...

Journal of Marine Science and Engineering, 2022 Cavitation inception predetermines a jump of noise radiated from marine vehicles. Usually marine propellers are the main sources of such a noise. In the situation of cavitation inception near the blade’s leading edge, its prediction remains a challenge ...

Degenerated Boundary Layers and Long-Wave Low-Frequency Motion in High-Contrast Elastic Laminates
Mathematics, 2023 The effect of high contrast on the multiscale behaviour of elastic laminates is studied. Mathematical modelling in this area is of significant interest for a variety of modern applications, including but not limited to advanced sandwich structures and ...

Gaps of size 2, 4, and (conditionally) 6 between successive odd composite numbers occur infinitely often [PDF]
Notes on Number Theory and Discrete MathematicsThe infinite sequence of gaps (first differences) between successive odd composite numbers contains only the numbers 2, 4, and 6. We prove that, for any natural number k, the sequence of gaps contains infinitely many k-tuplets of consecutive gaps all ...

Моделирование и анализ информационных систем, 2016 For a second order equation with a small factor at the highest derivative the asymptotic behavior of all eigenvalues of periodic and antiperiodic problems is studied. The main assumption is that the coefficient at the first derivative in the equation is the
