Particle relabelling symmetries and Noether's theorem for vertical slice models [PDF]
, 2018 We consider the variational formulation for vertical slice models introduced in Cotter and Holm (Proc Roy Soc, 2013). These models have a Kelvin circulation theorem that holds on all materially-transported closed loops, not just those ...

Vertical profile reconstruction with Pol-InSAR data of a subpolar glacier [PDF]
, 2007 The last decade has seen an increasing demand for accurate mapping and wide-coverage monitoring of glaciers and ice sheets in order to measure and predict their response to global climate change and their contribution to sea level rise.

Three-dimensional geoacoustic perturbative inverse technique for the shallow ocean water column [PDF]
, 2013 textThis work focuses on developing an inversion scheme to estimate water-column sound-speed fields in three dimensions. The inversion scheme is based on a linearized perturbative technique which utilizes estimates of modal travel times.

Simultaneous multi-slice reconstruction by Regularized Nonlinear Inversion
, 2016 Increasing imaging speed is of utmost importance in in-vivo magnetic resonance imaging (MRI). With simultaneous multi-slice (SMS) MRI we can simultaneously acquire several slices of an object, which allows for higher undersampling factors compared to ...

An adaptive multiscale algorithm for efficient extended waveform inversion
, 2017 Subsurface-offset extended full-waveform inversion (FWI) may converge to kinematically accurate velocity models without the low-frequency data accuracy required for standard data-domain FWI.

Advances in crosshole seismic reflection processing [PDF]
, 1993 In recent years there have been significant advances in the acquisition and processing of crosshole seismic reflection data, and the method has been shown to be a high resolution imaging technique.
Rowbotham, Peter S
