(SpringerOpen, 2020-07-04)In this paper, we present geometric Hardy inequalities for the sub-Laplacian in half-spaces of stratified groups. As a consequence, we obtain the following geometric Hardy inequality in a half-space of the Heisenberg group ...
-
(AIMS Press, 2020-06-05)A tick-borne disease model is considered with nonlinear incidence rate and piecewise constant delay of generalized type. It is known that the tick-borne diseases have their peak during certain periods due to the life cycle ...
-
(MDPI, 2021-11-30)Numerical flow simulations play an important role in polymer processing. One of the essential prerequisites for accurate and precise flow simulations is to obtain accurate materials functions. In the framework of the ...
-
(Nazarbayev University School of Sciences and Humanities, 2022)In this paper we consider Totally Asymmetric Simple Exclusion Process. We give some joint distribution of particles’ positions in TASEP by using the transition probabilities of N-particle systems.
-
(Alexandria Engineering Journal, 2021-10-27)Fractional differential equations with constant coefficients can be readily handled by a number of methods, but those with variable coefficients are much more challenging. Recently, a method has appeared in the literature ...
-
(OXFORD UNIV PRESS, 2019-03)We prove L-P-Caffarelli-Kohn-Nirenberg type inequalities on homogeneous groups, which is one of most general subclasses of nilpotent Lie groups, all with sharp constants. We also discuss some of their consequences. Already ...
-
(Nazarbayev University School of Sciences and Humanities, 2018-05-12)We compare manual and automatic approaches to the problem of extracting bitexts from the Web in the framework of a case study on building a Russian-Kazakh parallel corpus. Our findings suggest that targeted, site-specific ...
-
(Nazarbayev University School of Sciences and Humanities, 2020)Ceramic paste extrusion process, such as 3D printing, is commonly used for fabricating high quality products, like catalyst pellets for heterogeneous catalytic reactors, porous catalyst for cleaning gas released from an ...
-
(Nazarbayev University School of Sciences and Humanities, 2020-05-01)There has been great interest in membrane reactors over the last decades. The limitation of selectivity and yield of certain products in chemical reactions is an important and not sfficiently solved problem in the field ...
-
(Nazarbayev University School of Sciences and Humanities, 2021-05)Diffusion-reaction processes in chemical reactors are often modelled by differential equations of diffusion-reaction type that describe the change in time and space of concentrations of chemical species. In this work, ...
-
(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 ...
-
(Nazarbayev University School of Sciences and Humanities, 2020-04-30)In this project, the bivariate dependence structures between the Japanese Yen, Chinese Yuan, and Hong Kong Dollar exchange rates against the US Dollar are studied by using time-invariant and time-varying copulas. The ...
-
(MDPI AG, 2021-06-10)In the polymer sheet processing industry, the primary objective when designing a coat-hanger die is to achieve a uniform velocity distribution at the exit of the extrusion die outlet. This velocity distribution depends on ...
-
(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 ...
-
(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 ...
-
(Nazarbayev University School of Sciences and Humanities, 2020)The Nonlinear Schrödinger-Airy equation is one of the general examples of dispersive nonlinear partial differential equations. It is commonly used to characterize the nonlinear propagation of light pulses in optical ...
-
NUMERICAL MODELING OF THERMAL FLOWS IN ENTRANCE CHANNELS FOR POLYMER EXTRUSION: A PARAMETRIC STUDY (Processes, 2020-10)Flow distribution channels in extrusion dies are typically designed to assure uniform fluid velocity, pressure and temperature in the outlets. To ensure this uniformity, it is desirable to have the fluid melt to reach a ...
-
(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 ...
-
(Journal of Mathematical Analysis and Applications, 2022)Persistence of spatial analyticity is studied for solution of the beam equation utt + (m + Δ2) u + |u| p−1u = 0 on Rn × R. In particular, for a class of analytic initial data with a uniform radius of analyticity σ0, we ...
-
(National Academy of Science of Ukraine, 2018-01-18)In this paper we study some conditional probabilities for the totally asymmetric simple exclusion processes (TASEP) with second class particles. To be more specific, we consider a finite system with one first class particle ...
