Theories and heat pulse experiments of non-Fourier heat conduction

open access: yes, 2015
The experimental basis and theoretical background of non-Fourier heat conduction is shortly reviewed from the point of view of non-equilibrium thermodynamics. The performance of different theories is compared in case of heat pulse experiments.Comment: 12

A facile method for the estimation of ceramic performance in light armor systems

open access: yesInternational Journal of Ceramic Engineering & Science
Ballistic armor material development has been historically constrained by the limitations of existing predictive models. Traditional approaches, primarily reliant on finite element models, are not only computationally intensive but also often fall short ...

Extending ballistic graphene FET lumped element models to diffusive devices [PDF]

open access: yes, 2012
In this work, a modified, lumped element graphene field effect device model is presented. The model is based on the "Top-of-the-barrier" approach which is usually valid only for ballistic graphene nanotransistors.
