Refined Green–Lindsay Model for the Response of Skin Tissue under a Ramp-Type Heating

Mathematics, 2023
Based on Green–Lindsay generalized thermoelasticity theory, this paper presents a new refined higher-order time-derivative thermoelasticity model. Thinner one-dimensional skin tissue is considered when its inner surface is free of traction and does not ...

Different Numerical Inversion Algorithms of the Laplace Transform for the Solution of the Advection-Diffusion Equation with Non-local Closure in Air Pollution Modeling

Trends in Computational and Applied Mathematics, 2018
In this paper, a three-dimensional solution of the steady-state advection-diffusion equation is obtained applying the Generalized Integral Advection Diffusion Multilayer Technique (GIADMT), considering non-local closure for turbulent flow. Two different

Absorption illumination of a 2D rotator semi-infinite thermoelastic medium using a modified Green and Lindsay model

Case Studies in Thermal Engineering, 2021
In this work, the effect of rotation field can be studied during the modified Green and Lindsay model (MGL). The two dimensional (2D)elastic medium is exposed to thermal influences caused by surface absorption of (pulsed) laser radiation.

Application of inverse solution in two‐dimensional heat conduction problem using Laplace transformation

Heat Transfer—Asian Research, 2002
AbstractAn inverse solution has been explicitly derived for two‐dimensional heat conduction in cylindrical coordinates using the Laplace transformation. The applicability of the inverse solution is checked using the numerical temperatures with a normal random error calculated from the corresponding direct solution. For a gradual temperature change in a

Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

Advanced Materials, EarlyView.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...
