Inverse problem by Cauchy data on arbitrary subboundary for system of elliptic equations
, 2012 We consider an inverse problem of determining coefficient matrices in an $N$-system of second-order elliptic equations in a bounded two dimensional domain by a set of Cauchy data on arbitrary subboundary.

The numerical solution of forward and inverse Robin problems for Laplace’s equation
Boundary Value Problems, 2019 The Robin boundary value problem for Laplace’s equation in the elliptic region (which is a forward problem) and its related inverse problem can be used to reconstruct Robin coefficients from measurements on a partial boundary (inverse problem).

Dimension-Independent MCMC Sampling for Inverse Problems with Non-Gaussian Priors [PDF]
, 2014 The computational complexity of MCMC methods for the exploration of complex probability measures is a challenging and important problem. A challenge of particular importance arises in Bayesian inverse problems where the target distribution may be ...

Inverse boundary-value problems: Elliptic equations
Journal of Mathematical Analysis and Applications, 1970 AbstractInverse, or identification, problems are currently receiving a great deal of attention in virtually all scientific disciplines. Most of the work done so far has dealt with systems governed by ordinary differential equations. This paper points out that the methods most commonly used for these problems are not suitable for inverse problems ...

An Efficient Double Parameter Elliptic Curve Digital Signature Algorithm for Blockchain
IEEE Access, 2021 The classic Elliptic curve digital Signature Algorithm (ECDSA) uses one inversion operation in the process of signature and verification, which greatly reduces the efficiency of digital signatures.
