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

Electronic 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 ...

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

Bruno 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.

Statistical inference for inverse problems [PDF]

In this paper we study statistical inference for certain inverse problems. We go beyond mere estimation purposes and review and develop the construction of confidence intervals and confidence bands in some inverse problems, including deconvolution and ...

Solving inverse problems via weak contractive maps

Journal 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

Journal 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 ...

Reconstructing discrete measures from projections. Consequences on the empirical Sliced Wasserstein Distance

Comptes Rendus. Mathématique
This paper deals with the reconstruction of a discrete measure $\gamma _Z$ on $\mathbb{R}^d$ from the knowledge of its pushforward measures $P_i\#\gamma _Z$ by linear applications $P_i: \mathbb{R}^d \rightarrow \mathbb{R}^{d_i}$ (for instance projections

Physics‐Informed Neural Network for Magnetization Distribution Estimation

IET 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
