Solution of neutron diffusion equation in 2d polar (r,theta) coordinates using Nodal Integral Method
, 2017 The nodal methods are significantly more accurate than the traditional methods such as finite difference method (FDM), finite element method (FEM) etc. However, these methods can be used only for the nodes of only a few limited shapes such as rectangular

Nodal frequency-constrained energy storage planning via hybrid data-model driven methods
iEnergyCross-regional high voltage direct current (HVDC) systems bring remarkable renewable power injections to the receiver side of power grids. However, HVDC failures result in large disturbances to receivers and cause critical frequency security problems ...

On nodal solutions of the Yamabe equation on products
Journal of Geometry and Physics, 2009 Usually, one looks for positive solutions of the Yamabe equation. However, solutions which change signs, called \textit{nodal}, are also important. In this case, the equation takes the form \(L_g(u)=\lambda|u|^{p-2}u\), where \(L_g\) is the Yamabe operator associated to the Riemannian metric \(g\).

The Nodal Sets of Solutions to Parabolic Equations
In this paper, we study the parabolic equations $\partial_t u=\partial_j\left(a^{ij}(x,t)\partial_iu\right)+b^j(x,t)\partial_ju+c(x,t)u$ in a domain of $\mathbb{R}^n$ under the condition that $a^{ij}$ are Lipschitz continuous. Consider the nodal set $Z_t=\{x: u(x,t)=0\}$ at a time $t$-slice. Simple examples show that the singular set $\mathcal{S}_t=\{x:

ON NODAL SETS AND NODAL DOMAINS ON S 2 AND R 2
, 2008 . We discuss possible topological configurations of nodal sets, in particular the number of their components, for spherical harmonics on S 2. We also construct a solution of the equation ∆u = u in R 2 that has only two nodal domains. This equation arises
