Exact controllability for a string equation in domains with moving boundary in one dimension
Electronic Journal of Differential Equations, 2015 We consider a string equation in a domain with moving boundary. By using the multiplier method in non-cylindrical domains, we establish the exact boundary controllability in domains with moving boundary, and obtain a weaker condition on the time ...

Advanced Engineering Materials, EarlyView.This study investigates thermo‐chemical processes during high‐temperature testing of two commercial MgO‐C brick grades, one containing 47.5 wt.% MgO‐C recyclate. Using ETV, DTA/TG‐MS, XRD, and SEM/EDS/EBSD, mechanisms such as carbothermal reduction of magnesia, impurity incorporation into the secondary MgO surface layer, and calcium‐rich phase ...

The $L^{p}$ regularity problem for the heat equation in non-cylindrical domains
Illinois Journal of Mathematics, 1999 The authors consider the Dirichlet problem for the heat equation in a domain with minimally smooth boundary. They obtain sharp \(L^p\) estimates fo the parabolic non tangential maximal function of the gradient of the solutions.

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio
Advanced Engineering Materials, EarlyView.This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...

Solvability of second-order boundary-value problems on non-smooth cylindrical domains
Electronic Journal of Differential Equations, 2013 In this note, we present an abstract approach for the study of a second-order boundary-value problem on cusp domain. This study is performed in the framework of anisotropic little Holder spaces.

On the wave equations with memory in noncylindrical domains
Electronic Journal of Differential Equations, 2007 In this paper we prove the exponential and polynomial decays rates in the case $n > 2$, as time approaches infinity of regular solutions of the wave equations with memory $$ u_{tt}-Delta u+int^{t}_{0}g(t-s)Delta u(s)ds=0 quad mbox{in } widehat{Q ...
