An inverse eigenvalue problem for an arbitrary multiply connected bounded region in R2
International Journal of Mathematics and Mathematical Sciences, 1991 The basic problem is to determine the geometry of an arbitrary multiply connected bounded region in R2 together with the mixed boundary conditions, from the complete knowledge of the eigenvalues {λi}j=1∞ for the Laplace operator, using the asymptotic ...

Inverse Spectral Problem for the Laguerre Differential Operator
Journal of Mathematical Analysis and Applications, 1998 In [SIAM Rev. 34, 118-119 (1992)] \textit{A. Zayed} asked whether there exists a perturbation of the Laguerre operator (with boundary condition at \(0\) that leads to the Friedrichs extension) which has a given equally spaced sequence of real numbers, bounded neither from above nor from below, as its spectrum.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Advanced Materials Technologies, EarlyView.This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

A unified approach to solve ill-posed inverse problems in econometrics [PDF]
We consider the general issue of estimating a nonparametric function x from the inverse problem r = Tx given estimates of the function r and of the linear transform T. Two typical examples include the estimation of a probability density function fromdata

Inverse spectral problem for quantum graphs
, 2005 The inverse spectral problem for the Laplace operator on a finite metric graph is investigated. It is shown that this problem has a unique solution for graphs with rationally independent edges and without vertices having valence 2. To prove the result, a
