Multiple nonsymmetric nodal solutions for quasilinear Schrödinger system

Electronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper, we consider the quasilinear Schrödinger system in $\mathbb R^{N}$ ($N\geq3$): \begin{equation*} \begin{cases} -\Delta u+ A(x)u-\frac{1}{2}\Delta(u^{2})u=\frac{2\alpha }{\alpha+\beta}|u|^{\alpha-2}u|v|^{\beta},\\ -\Delta v+ Bv-\frac{1}{2}\

Global bifurcation and nodal solutions for homogeneous Kirchhoff type equations

Electronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper, we shall study unilateral global bifurcation phenomenon for the following homogeneous Kirchhoff type problem \begin{equation*} \begin{cases} -\left(\int_0^1 \left\vert u'\right\vert^2\,dx\right)u''=\lambda u^3+h(x,u,\lambda)&\text{in}\,\, (

Multiphysics modeling of a reactivity insertion transient at different fidelity levels in support to the safety assessment of a SMART-like small modular reactor

Frontiers in Energy Research, 2023
Typical design basis accidents such as the control Rod Ejection Accident (REA) will need to be evaluated during the safety analysis in support the licensing processes for most of the current Small Modular Reactors (SMRs) designs.

Nodal Accuracy Improvement Technique for Linear Elements with Application to Adaptivity

Applied Sciences, 2023
In the finite element method, the conventional linear elements have long been precluded, due to their low accuracy of nodal displacements, from the analysis of super-convergence and adaptivity via the element energy projection (EEP) technique.

Nodal solutions of weighted indefinite problems [PDF]

Journal of Evolution Equations, 2020
This paper analyzes the structure of the set of nodal solutions of a class of one-dimensional superlinear indefinite boundary values problems with an indefinite weight functions in front of the spectral parameter. Quite astonishingly, the associated high order eigenvalues might not be concave as it is the lowest one.

Verification of a two-step code system MCS/RAST-F to fast reactor core analysis

Nuclear Engineering and Technology, 2022
RAST-F is a new full-core analysis code based on the two-step approach that couples a multi-group cross-section generation Monte-Carlo code MCS and a multi-group nodal diffusion solver.

Nodal solutions for (𝑝,2)-equations

Transactions of the American Mathematical Society, 2014
In this paper, we study a nonlinear elliptic equation driven by the sum of a p p -Laplacian and a Laplacian ( ( p , 2 ) \left ( p,2\right ) -equation), with a Carathéodory ( p − 1 ) \left ( p-1\right ) -(sub-)linear reaction.
