The Linearized Inverse Boundary Value Problem in Strain Gradient Elasticity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper we study the linearized version of the strain gradient elasticity equation in ℝ2$$ {\mathbb{R}}^2 $$ with constant coefficients and we prove that one can determine the two Lamé coefficients λ,μ$$ \lambda, \mu $$ as well as the internal strain gradient parameter g$$ g $$, as indicated by Mindlin in his revolutionary papers in 1963–

On construction of converging sequences to solutions of boundary value problems

Mathematical Modelling and Analysis, 2010
We consider the Dirichlet problem x″ = f(t,x), x(a) = A, x(b) = B under the assumption that there exist the upper and lower functions. We distinguish between two types of solutions, the first one, which can be approximated by monotone sequences of ...

Numerical Investigation of a Diffusive SIR Model: Focus on Positivity Preservation

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a system of semilinear partial differential equations (PDEs) representing a spatially extended SIR epidemic model. A brief analytical investigation of the well‐posedness and positivity of the solutions is provided in the appendix, while the main focus is on the numerical treatment of the model.

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

ON A BOUNDARY-VALUE PROBLEM FOR THE POISSON EQUATION AND THE CAUCHY–RIEMANN EQUATION IN A LENS

Проблемы анализа
In this paper, we consider the Dirichlet boundary-value problem for complex partial differential equations in a lens. With the help of the harmonic Green function, the Dirichlet boundary-value problem is solved explicitly for the Poisson equation in a ...

Mesh design for electrical resistivity imaging of agricultural dikes

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity imaging (ERI) shows promise for investigating earthen flood barriers. We are interested in the applicability of ERI for aiding maintenance and construction efforts on agricultural dikes in the upper Bay of Fundy, Canada.

From Inclusion to Sustainability: A Systematic Review of Research Trends in Sustainable Inclusive Education (2015–2025)

Sustainable Development, EarlyView.
ABSTRACT This systematic review reconceptualizes inclusive education (IE) as a cross‐cutting strategy for sustainable development. We analyze 2729 articles published between 2015 and 2025, identifying 357 that explicitly address sustainability. Using PRISMA 2020, bibliometric mapping, and binomial generalized linear models, we examine temporal ...

HARMONIC FUNCTION

مجلة جامعة الزيتونة, 2022
 In this paper, we present an innovative idea of the harmonic functions. In order to do this, we first present the most important theories related to harmonic functions and put forward the idea of harmonic conjugate.
