The Application of Piecewise Regularization Reconstruction to the Calibration of Strain Beams
Standard beams are mainly used for the calibration of strain sensors using their load reconstruction models. However, as an ill-posed inverse problem, the solution to these models often fails to converge, especially when dealing with dynamic loads of ...

Wavelength and Polarization Multiplexed Nonlocal Metasurface for Quantitative Phase Microscopy
A nonlocal metasurface with wavelength and polarization multiplexed optical transfer functions is demonstrated for performing quantitative phase imaging. The metasurface uses the angular dispersion of optical routing guided mode resonances to extract phase gradient information along different directions for phase retrieval. ABSTRACT Imaging transparent

Reconstruction of a source term in a parabolic integro-differential equation from final data
The identification of a source term in a parabolic integro-differential equation is considered. We study the existence of the quasi-solution to this problem, Tikhonov regularization and a related gradient method.

Tikhonov regularized exterior penalty methods for hierarchical variational inequalities
We consider nested variational inequalities con- sisting in a (upper-level) variational inequality whose feasible set is given by the solution set of another (lower-level) variational inequality. This class of hierarchical equilibrium contains a wealth of important applications, including purely hierarchical convex bilevel optimization problems and ...

On a Stochastic Regularization Technique for Ill-Conditioned Linear Systems
Knowledge about the input–output relations of a system can be very important in many practical situations in engineering. Linear systems theory comes from applied mathematics as an efficient and simple modeling technique for input–output systems ...

Ill-posed problems arise in many areas of science and engineering. Tikhonov is a usual regularization which replaces the original problem by a minimization problem with a fidelity term and a regularization term.

Approximate controllability of a semilinear delayed heat equation Tikhonov regularization
In this work, we study approximate controllability of a semilinear heat equation with delay using the Tikhonov regularization. The considered problem for partial differential equation is transformed into an equivalent operator equation.
