(Nazarbayev University, School of Sciences and Humanities, 2023-08-28)This work investigates the fractional space-time behavior of the Fisher-KPP equation with initial boundary values. Notably, fractional versions of Fisher-KPP equations describe complex phenomena in cases where the classical ...
-
(School of Sciences and Humanities, 2023-07)Microelectromechanical systems (MEMS) have emerged as a revolutionary technology, enabling the development of miniaturized devices with diverse functionalities and superior performance. Among the essential components of ...
-
(Polymers, 2022)In the design of coat hanger extrusion dies, the main objective is to provide a uniform flow rate at the die exit. Previously, a multi-rheology isothermal method model for coat hanger extrusion dies was developed to reach ...
-
(School of Sciences and Humanities, 2023)This thesis presents an exploration of a variant of the multivariate Mittag-Leffler function, with a focus on its properties and applications in the context of solving differential equations. The work includes several ...
-
(School of Sciences and Humanities, 2023)This capstone project analyzes the application of the Elliott wave theory on time-series data from the Forex market. The project uses patternbased probabilistic models to test the validity of the Elliott wave theory and ...
-
(School of Sciences and Humanities, 2023)This thesis focuses on the polyharmonic Green’s function, one of fundamental concepts in mathematical analysis and partial differential equations. The Green’s function plays a crucial role in solving problems related to ...
-
(School of Sciences and Humanities, 2023)We solve inverse problems of determining continuous time-dependent source terms in evolution equations. As a particular case, one inverse initialboundary value problem with observation data at a spatial point is sufficient ...
-
(School of Sciences and Humanities, 2023)Obtaining synchronization in the activity of neural networks has been a major goal for scientists of various fields. Thus, several problems based on finite-time synchronization are to be explored in this paper. The primary ...
-
(School of Sciences and Humanities, 2023)Portfolio risk management is a process aimed at maintaining profit streams and reducing uncertainties in investment decisions. Value-at-Risk (VaR) is a widely used metric to quantify the potential loss of profits. Although ...
-
(School of Sciences and Humanities, 2023)This thesis investigates the finite time synchronization and fixed time synchronization of shunting inhibitory memristive neural networks with time-varying delays via sliding mode control. First, a new terminal sliding ...
-
(School of Sciences and Humanities, 2023)This project is aimed to analyze the exponential model, Von Bertalanffy model, and the dynamic carrying capacity model based on the Canada population data. The unknown parameters in these models would be found out by ...
-
(School of Sciences and Humanities, 2023)In this thesis, we examine inverse problems for the sub-elliptic heat equation with the Cauchy-Dirichlet initial-boundary value condition to determine the time-dependent control parameter. Consequently, on the Heisenberg ...
-
(Physica Scripta, 2022)A comparison of three different isotropic non-linear elastic models uncovers subtle but important differences in the acoustoelastic responses of a material slab that is subjected to dynamic deformations during a pump-probe ...
-
(Scientific Reports, 2022)Dead-core and non-dead-core solutions to the nonlinear diffusion–reaction equation based on the generalized diffusion flux with gradient-dependent diffusivity and the power-law reaction kinetics in catalyst slabs are ...
-
(Applied Mathematical Modelling, 2023)This paper considers control systems with impulses that are saturated and asymmetrically saturated which are used to examine the synchronization of inertial neural networks (INNs) with time-varying delay and coupling delays. ...
-
(Frontiers in Environmental Science, 2022-09-29)The present study empirically analyzes the role of eco-innovation in plummeting carbon dioxide (CO2) emissions in conjunction with renewable energy usage, foreign direct investment, and trade openness for the states in ...
-
(Applied Sciences, 2022-05-23)We consider non-Newtonian boundary-layer fluid flow, governed by a power-law OstwalddeWaele rheology. Boundary-layer flows of non-Newtonian fluids have far-reaching applications, and are very frequently encountered in ...
-
(Mathematics, 2021-08-03)In this paper, we study the dynamics of a fractional-order epidemic model with general nonlinear incidence rate functionals and time-delay. We investigate the local and global stability of the steady-states. We deduce ...
-
(Opuscula Mathematica, 2021)We obtain new sufficient criteria for the oscillation of all solutions of linear delay difference equations with several (variable) finite delays. Our results relax numerous well-known limes inferior-type oscillation ...
-
(Discrete and Continuous Dynamical Systems, 2022-12)This paper considers the one-dimensional Schrödinger equation with nonlocal nonlinearity that describes the interactions of nonlinear dispersive waves. We obtain some the local well-posedness and ill-posedness result ...
