Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Existence results for singular anisotropic elliptic boundary-value problems
Electronic Journal of Differential Equations, 2000 We establish the existence of a positive solution for anisotropic singular quasilinear elliptic boundary-value problems. As an example of the problems studied we have $$ u^au_{xx}+u^bu_{yy}+lambda(u+1)^{a+r}=0 $$ with zero Dirichlet boundary condition ...

Well-posedness of elliptic-parabolic differential problem with integral condition
Қарағанды университетінің хабаршысы. Математика сериясыIn this paper, we study a class of nonlocal boundary value problems for elliptic-parabolic equations subject to integral-type conditions. Such problems naturally emerge in various physical and engineering contexts, including diffusion processes in ...

k‐Selective Electrical‐to‐Magnon Transduction with Finite‐Element‐Resolved Sub‐Micron Nanoantennas
Advanced Physics Research, EarlyView.We introduce a coupled finite‐element‐finite‐difference framework that links impedance‐matched nanoantenna geometries to propagating spin‐wave dynamics, capturing skin effects, proximity effects, and taper leakage beyond uniform‐current models. Applied to coplanar‐waveguide and stripline nanoantennas on yttrium‐iron‐garnet, the simulations achieve ...

Semilinear elliptic boundary-value problems on bounded multiconnected domains
Electronic Journal of Differential Equations, 2005 A semilinear elliptic boundary-value problem on bounded multiconnected domains is studied. The authors prove that under suitable conditions, the problem may have no solutions in certain cases and many have one or two nonnegative solutions in some other ...

Boundary Value Problems for Singular Elliptic Equations
Rocky Mountain Journal of Mathematics, 2011 Let \(\Omega\subset\mathbb R^N\) be a bounded domain with smooth boundary, \(a:\Omega\rightarrow [1,+\infty)\) a bounded function, \(h:[0,+\infty)\rightarrow\mathbb R\) continuous, and \(g:(0,+\infty)\rightarrow\mathbb R\) a continuous function such that \(\lim_{s\rightarrow 0^+}g(s)=+\infty\). Fix \(p>1\).
