An Intial-Value Technique for Self-Adjoint Singularly Perturbed Two-Point Boundary Value Problems
International Journal of Applied Mechanics and Engineering, 2020 In this paper, we present an initial value technique for solving self-adjoint singularly perturbed linear boundary value problems. The original problem is reduced to its normal form and the reduced problem is converted to first order initial value ...

Business Ethics, the Environment &Responsibility, Volume 34, Issue 4, Page 1412-1431, October 2025.Abstract Constructive Deviant Behavior (CDB) raises an ethical dilemma that poses a significant challenge within the realm of business ethics. This ethical dilemma is the extent to which individuals should be allowed, or even encouraged, to challenge established norms in the name of organizational and stakeholder well‐being before compromising ethical ...

Disentangling the effects of climate change in a mountain lake through community structure analysis
Limnology and Oceanography, Volume 70, Issue 8, Page 2142-2157, August 2025.Abstract Pressures of climate change may trigger regime shifts in ecosystems. Identifying signs of these pressures before the critical transition remains challenging, and it could be useful to anticipate the regime shift. In this research, while exploiting the case of a lacustrine ecosystem, which passed from an unvegetated, phytoplankton‐dominated ...

Neural Ordinary Differential Equations for Model Order Reduction of Stiff Systems
International Journal for Numerical Methods in Engineering, Volume 126, Issue 12, 30 June 2025.ABSTRACT Neural Ordinary Differential Equations (ODEs) represent a significant advancement at the intersection of machine learning and dynamical systems, offering a continuous‐time analog to discrete neural networks. Despite their promise, deploying neural ODEs in practical applications often encounters the challenge of stiffness, a condition where ...

Scaling Exponents of Turbulent Static Pressure Structure Function in the Inertial Subrange
Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.Abstract The measured variations in the turbulent static pressure structure function Dpp(r) ${D}_{pp}(r)$ with scale r $r$ in the roughness sublayer above a subarctic forest are empirically shown to exhibit exponents that are smaller than r4/3 ${r}^{4/3}$ predicted for the inertial subrange (ISR).

Septic B-spline method for second order self-adjoint singularly perturbed boundary-value problems
Ain Shams Engineering Journal, 2018 In the present paper, we develop a septic B-spline method for solving a self-adjoint singularly perturbed two-point boundary value problem. This method is applied directly to the numerical solution of the problems without reducing its order.

Singularly perturbed boundary value problems
Differential and Integral Equations, 1994 The author considers the system \(-\varepsilon^ 2 u''+g_ 1 (u,v,x,\varepsilon) =0\), \(v''+g_ 2(u,v,x,\varepsilon)=0\), \(v(0)=v(1)=u(0)=u(1)=0\), \(x \in[0,1]\), \(\varepsilon \neq 0\), where \(g_ 1\), \(g_ 2\) are continuous functions specially choosen by the author, \(\varepsilon\) is a small parameter.

Asymptotic Estimates of the Solution of a Restoration Problem with an Initial Jump
Journal of Applied Mathematics, 2014 The asymptotic behavior of the solution of the singularly perturbed boundary value problem Lεy=htλ,Liy+σiλ=ai,i=1,n+1̅ is examined. The derivations prove that a unique pair (ỹt,λ̃ε,ε,λ̃ε) exists, in which components y(t,λ̃ε,ε) and λ̃(ε) satisfy the ...

Singularly Perturbed Dirichlet Problems With Subquadratic Nonlinearities [PDF]
Transactions of the American Mathematical Society, 1987 Boundary and interior layer theory is provided for a class of singularly perturbed Dirichlet problems with subquadratic nonlinearities in the derivative terms. The results obtained generalize and extend well-known results on the semilinear problem.
