Non-Fourier heat transport in nanosystems

open access: yesLa Rivista del Nuovo Cimento, 2023
AbstractEnergy transfer in small nano-sized systems can be very different from that in their macroscopic counterparts due to reduced dimensionality, interaction with surfaces, disorder, and large fluctuations. Those ingredients may induce non-diffusive heat transfer that requires to be taken into account on small scales.

New approach for the determination of the characteristics of signals containing fluctuating harmonics [PDF]

open access: yesInternational Journal of Metrology and Quality Engineering, 2011
This paper describes a new approach for the analysis of signals containing fluctuating harmonics. It is based on the Fourier transform, using windowing to reduce the error arising from analysing the signal over a non integer number of signal periods and ...

Hybrid Fourier series and smoothing spline path non-parametrics estimation model

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
Pathway analysis is one way to determine whether there is a causal relationship between extrinsic and intrinsic factors. The linearity assumption is something that can change the model. The shape of the model is subject to linearity assumptions.

A new solution for nonlinear Dual Phase

open access: yesAlexandria Engineering Journal, 2016
The application of new methods to solution of non-Fourier heat transfer problems has always been one of the interesting topics among thermal science researchers. In this paper, the effect of laser, as a heat source, on a thin film was studied.

The non-Fourier image reconstruction method for the STIX instrument

open access: yesOpen Astronomy, 2020
In this work we aimed to develop the image reconstruction algorithm without any analytical simplifications and restrictions. In our method we abandon Fourier’s approach to image reconstruction, and instead use the number of counts recorded in each ...
