First-order gradient regularisation methods for image restoration: reconstruction of tomographic images with thin structures and denoising piecewise affine images
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsCentre for Mathematical SciencesJesus College, 2016-02-02)The focus of this thesis is variational image restoration techniques that involve novel non-smooth first-order gradient regularisers: Total Variation (TV) regularisation in image and data space for reconstruction of thin ...

Generalised nonlinear stability of stratified shear flows: adjoint-based optimisation, Koopman modes, and reduced models
(Department of Applied Mathematics and Theoretical Physics, University of CambridgeUniversity of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsSt John's College, 2016-10-04)In this thesis I investigate a number of problems in the nonlinear stability of density stratified plane Couette flow. I begin by describing the history of transient growth phenomena, and in particular the recent application ...

Standard model physics from an algebra?
(2015)This thesis constitutes a first attempt to derive aspects of standard model particle physics from little more than an algebra. Here, we argue that physical concepts such as particles, causality, and irreversible time may ...

The power spectrum and bispectrum of inflation and cosmic defects
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsGonville and Caius College, 2016-06-28)Much of the recent progress in cosmology has come from studying the power spectrum of the cosmic microwave background (CMB). The latest results from the Planck satellite confirmed that the inflationary paradigm with the ...
