plays a crucial role in solving problems related to ...
Kuangaliyeva, Dilyara(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 ...
Nuriyev, Zhangir(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 ...
Bolatbekov, Kairzhan(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 ...
Otkel, Madina(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 ...
Aiben, Ailiza(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 ...
Kamet, Madina(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 ...
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 ...
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 ...
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. ...
Rehman, Erum; Rehman, Shazia; Mumtaz, Ayesha; Jianglin, Zhang; Shahiman, Muhammad Ali(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 ...
Al-Ashhab, Samer; Wei, Dongming; Alyami, Salem A.; Azad, AKM; Moni, Mohammad Ali(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 ...
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 ...
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 ...
