Determination of point sources in vibrating beams by boundary measurements: Identifiability, stability, and reconstruction results

open access: yesElectronic Journal of Differential Equations, 2004
We consider two inverse problems of determining point sources in vibrating beams by boundary measurements. We show that the boundary observation at one extremity of the domain determines uniquely the sources for an arbitrarily small time of observation ...

Inverse Problems in Pump–Probe Spectroscopy

open access: yesPhotochem
Ultrafast pump–probe spectroscopic studies allow for deep insights into the mechanisms and timescales of photophysical and photochemical processes. Extracting valuable information from these studies, such as reactive intermediates’ lifetimes and coherent

Reconstruction of a convolution kernel in a parabolic problem with a memory term in the boundary conditions

open access: yesBruno Pini Mathematical Analysis Seminar, 2013
We consider the problem of the reconstruction of the convolution kernel, together with the solution, in a semilinear integrodiential parabolic problem in the case that in the boundary conditions, there appear quite general memory operators.

Solving inverse problems via weak contractive maps

open access: yesJournal of Numerical Analysis and Approximation Theory, 2008
We prove a "collage'' theorem for weak contractive maps and we use it for inverse problems.

Exploiting diurnal temperature variations to monitor the growth of tubers

open access: yesJournal of Mathematics in Industry
We propose to use diurnal temperature variations for nondestructive monitoring of growing tubers and investigate the feasibility by numerically simulating the data collected with a grid of passive thermal sensors placed in the ground and sampled at ...

Physics‐Informed Neural Network for Magnetization Distribution Estimation

open access: yesIET Electric Power Applications
Accurately estimating the magnetization distribution in permanent magnets is critical for optimising their performance in various applications, such as electric motors, generators and magnetic sensors, where precise magnetic field control is essential. A
