APPROXIMATION OF POSITIONAL IMPULSE CONTROLS FOR DIFFERENTIAL INCLUSIONS

open access: yesUral Mathematical Journal, 2022
Nonlinear control systems presented as differential inclusions with positional impulse controls are investigated. By such a control we mean some abstract operator with the Dirac function concentrated at each time. Such a control ("running impulse"), as a

Installation effect of rigid inclusions in soft clay improvement

open access: yesAin Shams Engineering Journal, 2023
Rigid Inclusions have been increasingly used as a successful technique for improving soft clay deposits. This technique was first introduced by Menard in the 1990s and is known commercially as Controlled Modulus Columns (CMC’s) [1]. Unlike ordinary piles

On the enhancement of thermal transport of Kerosene oil mixed TiO2 and SiO2 across Riga wedge

open access: yesCase Studies in Thermal Engineering, 2022
Efficient thermal transportation in compact heat density gadgets is a prevailing issue to be addressed. The flow of a mono nanofluid (SiO2/Kerosene oil) and hybrid nanofluid (TiO2 + SiO2/Kerosene oil) is studied in context of Riga wedge.

A Discontinuous ODE Model of the Glacial Cycles with Diffusive Heat Transport

open access: yesMathematics, 2020
We present a new discontinuous ordinary differential equation (ODE) model of the glacial cycles. Model trajectories flip from a glacial to an interglacial state, and vice versa, via a switching mechanism motivated by ice sheet mass balance principles ...

Accurate Approximating Solution of the Differential Inclusion Based on the Ordinary Differential Equation

open access: yesUkrainian Mathematical Journal, 2021
UDC 517.9 Many problems in applied mathematics can be transformed and described by the differential inclusion involving which is a normal cone to a closed convex set at The Cauchy problem of this inclusion is studied in the paper. Since the change of leads to the change of solving the inclusion becomes extremely complicated.

Nonlinear second-order multivalued boundary value problems [PDF]

open access: yes, 2003
In this paper we study nonlinear second-order differential inclusions involving the ordinary vector $p$-Laplacian, a multivalued maximal monotone operator and nonlinear multivalued boundary conditions.

On the Filippov-Ważewski relaxation theorem for a certain class of fractional differential inclusions

open access: yesFractional Calculus and Applied Analysis, 2023
The purpose of this text is to propose an attempt of an extension of the Filippov-Ważewski Relaxation Theorem for a certain class of fractional differential inclusions.

Some Applications Related to Differential Inclusions Based on the Use of a Weighted Space

open access: yesFundamental Journal of Mathematics and Applications, 2023
In this paper, we present an existence theorem for the problem of discontinuous dynamical system related to ordinary differential inclusion, based on the use of the concepts related to weighted spaces introduced by Gorka and Rybka, without using any ...

Discrete Approximations of a Controlled Sweeping Process [PDF]

open access: yes, 2014
The paper is devoted to the study of a new class of optimal control problems governed by the classical Moreau sweeping process with the new feature that the polyhe- dral moving set is not fixed while controlled by time-dependent functions.

On existence of solution in $\mathbb R^n$ of stochastic differential inclusions with current velocities in the presence of approximations with uniformly bounded first partial derivatives

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
Notion of mean derivatives was introduced by Edward Nelson for the needs of stochastic mechanics (a version of quantum mechanics). Nelson introduced forward and backward mean derivatives while only their half-sum, symmetric mean derivative called current
