Physics-informed neural networks with hard constraints for inverse design [PDF]
SIAM Journal on Scientific Computing, 2021 Inverse design arises in a variety of areas in engineering such as acoustic, mechanics, thermal/electronic transport, electromagnetism, and optics. Topology optimization is a major form of inverse design, where we optimize a designed geometry to achieve ...

An inverse problem for the fractional Schrödinger equation in a magnetic field [PDF]
Inverse Problems, 2019 This paper shows global uniqueness in an inverse problem for a fractional magnetic Schrödinger equation (FMSE): an unknown electromagnetic field in a bounded domain is uniquely determined up to a natural gauge by infinitely many measurements of solutions

Convexification for an inverse parabolic problem [PDF]
Inverse Problems, 2020 A convexification-based numerical method for a coefficient inverse problem for a parabolic PDE is presented. The key element of this method is the presence of the so-called Carleman weight function in the numerical scheme.

Analysis of Dipolar Sources in the Solution of the Electroencephalographic Inverse Problem
Mathematics, 2022 In this work, we propose a solution to the problem of identification of sources in the brain from measurements of the electrical potential, recorded on the scalp EEG (electroencephalogram), where boundary problems are used to model the skull, brain ...

Machine learning inverse problem for topological photonics [PDF]
Communications Physics, 2018 Topology opens many new horizons for photonics, from integrated optics to lasers. The complexity of large-scale devices asks for an effective solution of the inverse problem: how best to engineer the topology for a specific application?

The inverse minisum circle location problem [PDF]
Yugoslav Journal of Operations Research, 2022 Let n weighted points be given in the plane. The inverse version of the minisum circle location problem deals with modifying the weights of points with minimum cost, such that the sum of the weighted distances from the circumference of a given circle C ...

INVERSE PARTITION PROBLEMS [PDF]
Bulletin of informatics and cybernetics, 1999 Summary: We analyze a partition problem and its inverse problem both in discrete variables and in two continuous ones through dynamic programming. We show that an inverse relation and an enveloping relation hold in each case. It is shown that an optimal solution for the discrete partition can be expressed through either an upper-semi-inverse function ...

A numerical method for an inverse source problem for parabolic equations and its application to a coefficient inverse problem [PDF]
Journal of Inverse and Ill-Posed Problems, 2019 Two main aims of this paper are to develop a numerical method to solve an inverse source problem for parabolic equations and apply it to solve a nonlinear coefficient inverse problem. The inverse source problem in this paper is the problem to reconstruct

Parallel Diffusion Models of Operator and Image for Blind Inverse Problems [PDF]
Computer Vision and Pattern Recognition, 2022 Diffusion model-based inverse problem solvers have demonstrated state-of-the-art performance in cases where the forward operator is known (i.e. non-blind). However, the applicability of the method to blind inverse problems has yet to be explored. In this

Category of quantizations and inverse problem
Nuclear Physics B, 2023 We introduce a category composed of all quantizations of all Poisson algebras. By the category, we can treat in a unified way the various quantizations for all Poisson algebras and develop a new classical limit formulation.
