On an inverse problem of nonlinear imaging with fractional damping

Barbara Kaltenbacher, William Rundell

This paper considers the attenuated Westervelt equation in pressure formulation. The attenuation is by various models proposed in the literature and characterised by the inclusion…

On the identification of the nonlinearity parameter in the Westervelt equation from boundary measurements

Barbara Kaltenbacher, William Rundell

We consider an undetermined coefficient inverse problem for a non-\\linear partial differential equation occurring in high intensity ultrasound propagation as used in acoustic tomo…

On uniqueness and reconstruction of a nonlinear diffusion term in a parabolic equation

Barbara Kaltenbacher, William Rundell

The problem of recovering coefficients in a diffusion equation is one of the basic inverse problems. Perhaps the most important term is the one that couples the length and time sca…

On the simultaneous recovery of the conductivity and the nonlinear reaction term in a parabolic equation

Barbara Kaltenbacher, William Rundell

This paper considers the inverse problem of recovering both the unknown, spatially-dependent conductivity and the nonlinear reaction term in a reaction-diffusion equa…

Uniqueness for an inverse coefficient problem for a one-dimensional time-fractional diffusion equation with non-zero boundary conditions

W. Rundell, M. Yamamoto

We consider initial boundary value problems for one-dimensional diffusion equation with time-fractional derivative of order which are subject to non-zero Neumann bound…

On the identification of source term in the heat equation from sparse data

William Rundell, Zhidong Zhang

We consider the recovery of a source term for the nonhomogeneous heat equation in where is a bounded domain in with smooth…
