Inverting the sound speed profile from multi-beam echo sounder data and historical measurements -- a simulation study
Yohann Gourret, Tommi Brander, Karl Thomas Hjelmervik
The ocean's opacity poses challenges for security, as new technology, e.g. underwater drones, offers new opportunities for illegal activities, such as smuggling and terrorism. A ne…
Inverse problems for a model of biofilm growth
Tommi Brander, Daniel Lesnic, Kai Cao
A bacterial biofilm is an aggregate of micro-organisms growing fixed onto a solid surface, rather than floating freely in a liquid. Biofilms play a major role in various practical…
Recovering a variable exponent
Tommi Brander, Jarkko Siltakoski
We consider an inverse problem of recovering the non-linearity in the one dimensional variable exponent -Laplace equation from the Dirichlet-to-Neumann map. The variable expo…
Optimal recovery of a radiating source with multiple frequencies along one line
Tommi Brander, Joonas Ilmavirta, Petteri Piiroinen +1
We study an inverse problem where an unknown radiating source is observed with collimated detectors along a single line and the medium has a known attenuation. The research is moti…
Boundary determination for hybrid imaging from a single measurement
Tommi Brander, Torbjørn Ringholm
We recover the conductivity at the boundary of a domain from a combination of interior and boundary data, with a single quite arbitrary measurement, in AET or CDII. The argumen…
Expected characteristic in Tunnels & Trolls character creation, with generalizations
Tommi Brander
In the roleplaying game Tunnels & Trolls the characteristics of player characters are determined by rolling dice in the following manner: First, one rolls three dice and calculates…
Photometric Redshift Calibration Requirements for WFIRST Weak Lensing Cosmology: Predictions from CANDELS
Shoubaneh Hemmati, Peter Capak, Daniel Masters +7
In order for Wide-Field Infrared Survey Telescope (WFIRST) and other Stage IV dark energy experiments (e.g., Large Synoptic Survey Telescope; LSST, and Euclid) to infer cosmologica…
Monotonicity and enclosure methods for the p-Laplace equation
Tommi Brander, Bastian von Harrach, Manas Kar +1
We show that the convex hull of a monotone perturbation of a homogeneous background conductivity in the -conductivity equation is determined by knowledge of the nonlinear Dirich…
Calderón's problem for p-Laplace type equations
Tommi Brander
We investigate a generalization of Calderón's problem of recovering the conductivity coefficient in a conductivity equation from boundary measurements. As a model equation we consi…
Superconductive and insulating inclusions for linear and non-linear conductivity equations
Tommi Brander, Joonas Ilmavirta, Manas Kar
We detect an inclusion with infinite conductivity from boundary measurements represented by the Dirichlet-to-Neumann map for the conductivity equation. We use both the enclosure me…
Enclosure method for the p-Laplace equation
Tommi Brander, Manas Kar, Mikko Salo
We study the enclosure method for the p-Calderón problem, which is a nonlinear generalization of the inverse conductivity problem due to Calderón that involves the p-Laplace equati…
Calderón problem for the p-Laplacian: First order derivative of conductivity on the boundary
Tommi Brander
We recover the gradient of a scalar conductivity defined on a smooth bounded open set in from the Dirichlet to Neumann map arising from the -Laplace equation. For…
