$L^p$ - $L^q$ estimates for damped wave equations with odd initial data

open access: yesElectronic Journal of Differential Equations, 2005
We study the Cauchy problem for the damped wave equation. In a previous paper [16] the author has shown the $L^p$ - $L^q$ estimates between the solutions of the damped wave equation and the solutions of the corresponding heat equation.

Acoustic multipole sources from the Boltzmann equation

open access: yes, 2013
By adding a particle source term in the Boltzmann equation of kinetic theory, it is possible to represent particles appearing and disappearing throughout the fluid with a specified distribution of particle velocities.

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

open access: yesAdvanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Complete discrimination System method for finding exact solutions, dynamical properties of combined Zakharsov-Kuznetsov-modified Zakarsov-Kuznetsov equation

open access: yesAlexandria Engineering Journal, 2023
The (2+1)-dimensional combined Zakharsov-Kuznetsov-modified Zakarsov-Kuznetsov (ZK-mZK) equation with constant co-efficients are solved by employing the complete discrimination system for polynomial Method (CDSPM).
