A Unified Analytical Approach to Fixed and Moving Boundary Problems for the Heat Equation
Mathematics, 2021 Fixed and moving boundary problems for the one-dimensional heat equation are considered. A unified approach to solving such problems is proposed by embedding a given initial-boundary value problem into an appropriate initial value problem on the real ...

Comparison of outflow boundary conditions for subsonic aeroacoustic simulations [PDF]
, 2011 Aeroacoustics simulations require much more precise boundary conditions than classical aerodynamics. Two classes of non-reflecting boundary conditions for aeroacoustics are compared in the present work: characteristic analysis based methods and Tam and ...

Characterization and Equilibrium Study of Drug Release of pH-Responsive Chitosan-graft-Maleic Film
International Journal of Technology, 2022 This paper reports on a pH responsive material and a mathematical model for a drug release study. This material can be applied as a tumor drug carrier, because the tumor tissue has a different pH (5.7–7.8) compared to the ...
