  • Designing a more nonlinearly stable laminar flow via boundary manipulation 

    Rabin, SME; Caulfield, Colm-cille Patrick; Kerswell, Richard Rodney (Cambridge University PressJournal of Fluid Mechanics, 2013-12-04)
    We show how a fully nonlinear variational method can be used to design a more nonlinearly stable laminar shear flow by quantifying the effect of manipulating the boundary conditions of the flow. Using the example of plane ...

  • Height and Gradient from Shading 

    Unknown author (1989-05-01)
    The method described here for recovering the shape of a surface from a shaded image can deal with complex, wrinkled surfaces. Integrability can be enforced easily because both surface height and gradient are represented. ...

  • Mathematical imaging methods for mitosis analysis in live-cell phase contrast microscopy 

    Grah, Joana Sarah; Harrington, JA; Koh, SB; Pike, JA; Schreiner, A; Burger, M; Schönlieb, Carola-Bibiane; Reichelt, S (ElsevierMethods, 2017-02-15)
    In this paper we propose a workflow to detect and track mitotic cells in time-lapse microscopy image sequences. In order to avoid the requirement for cell lines expressing fluorescent markers and the associated phototoxicity, ...
