  • A study of discontinuous Galerkin methods for thin bending problems 

    Dung, NT; Wells, Garth Nathan (Computational Mechanics: Solids Structures and Coupled ProblemsComputational Mechanics: Solids Structures and Coupled Problems, 2006)
    Various continuous/discontinuous Galerkin formulations are examined for the analysis of thin plates. These methods rely on weak imposition of continuity of the normal slope across element boundaries. We draw here upon ...

  • A Symplectic Prolegomenon 

    Smith, Ivan (American Mathematical SocietyBulletin of the American Mathematical Society, 2014)
    A symplectic manifold gives rise to a triangulated A∞-category, the derived Fukaya category, which encodes information on Lagrangian submanifolds and dynamics as probed by Floer cohomology. This survey aims to give some ...

  • A systems approach to improving patient safety through medical device purchasing 

    Hinrichs, Saba (University of CambridgeDepartment of EngineeringSt John's College, 2010-10-12)
    The purchase of medical devices involves engaging various stakeholders as well as balancing clinical, technical and financial requirements. Failure to consider these requirements can lead to wider consequences in the ...

  • A Theory of Object Recognition: Computations and Circuits in the Feedforward Path of the Ventral Stream in Primate Visual Cortex 

    Unknown author (2005-12-19)
    We describe a quantitative theory to account for the computations performed by the feedforward path of the ventral stream of visual cortex and the local circuits implementing them. We show that a model instantiating the ...

  • A Tool for the Spectral Analysis of the Laser Doppler Anemometer Data of the Cambridge Stratified Swirl Burner 

    Zhou, Ruigang; Balusamy, Saravanan; Hochgreb, Simone (Department of Engineering, University of Cambridge, 2012-06-08)
    A series of flow fields generated by a turbulent methane/air stratified swirl burner are investigated using laser Doppler anemometer (LDA). The LDA provides flow field measurements with comparatively high temporal resolutions. ...

  • A two-fluid model for locomotion under self-confinement 

    Reigh, Shang-Yik; Lauga, Eric Jean-Marie (American Physical SocietyPhysical Review Fluids, 2017-09-01)
    The bacterium Helicobacter pylori causes ulcers in the stomach of humans by invading mucus layers protecting epithelial cells. It does so by chemically changing the rheological properties of the mucus from a high-viscosity ...

  • A two-zone model for natural cross-ventilation 

    Carrilho da Graça, G; Daish, Nicholas Charles; Linden, Paul Frederick (ElsevierBuilding and Environment, 2015-07-01)
    Cross-ventilation flows (CV) are characterized by significant inflow momentum conservation as fluid flows across an enclosed rectangular volume as a confined jet. When the inflow area is smaller than the volume cross-sectional ...

  • A unified framework for resource-bounded autonomous agents interacting with unknown environments 

    Ortega, Pedro Alejandro Jr (University of CambridgeDepartment of Engineering, 2011-07-12)
    The aim of this thesis is to present a mathematical framework for conceptualizing and constructing adaptive autonomous systems under resource constraints. The first part of this thesis contains a concise presentation of ...

  • A Unified Information Theoretic Framework for Pair- and Group-wise Registration of Medical Images 

    Unknown author (2006-01-25)
    The field of medical image analysis has been rapidly growing for the past two decades. Besides a significant growth in computational power, scanner performance, and storage facilities, this acceleration is partially due ...

  • A Unified Statistical and Information Theoretic Framework for Multi-modal Image Registration 

    Unknown author (2004-04-28)
    We formulate and interpret several multi-modal registration methods inthe context of a unified statistical and information theoretic framework. A unified interpretation clarifies the implicit assumptionsof each method ...

  • A Variational Model for Joint Motion Estimation and Image Reconstruction 

    Burger, Martin; Dirks, Hendrik; Schönlieb, Carola-Bibiane (Society for Industrial and Applied MathematicsSIAM Journal on Imaging Sciences, 2018-01)
    The aim of this paper is to derive and analyze a variational model for the joint estimation of motion and reconstruction of image sequences, which is based on a time-continuous Eulerian motion model. The model can be set ...

  • A WKB approximation of elastic waves travelling on a shell of revolution 

    Morsbøl, JO; Sorokin, SV; Peake, Nigel (ElsevierJournal of Sound and Vibration, 2016-08-04)
    This paper is concerned with the elastic waveguide properties of an infinite pipe with circular cross section whose radius varies slowly along its length. The equations governing the elastodynamics of such shells are derived ...

  • A Yellow Polariton Condensate in a Dye Filled Microcavity 

    Cookson, T; Georgiou, K; Zasedatelev, A; Grant, RT; Virgili, T; Cavazzini, M; Galeotti, F; Clark, C; Berloff, Natalia G; Lidzey, DG; Lagoudakis, PG (WileyAdvanced Optical Materials, 2017-09-18)
    Polariton condensation in the yellow part of the visible spectrum from a planar organic semiconductor microcavity containing the molecular dye bromine-substituted boron-dipyrromethene is observed. This study provides ...

  • A-Three Dimensional Numerical Simulator for Expansion-Drive Reservoirs 

    Ismaila, Nurudeen Dele (2013-05-25)
    Every simulation study is a unique process, starting from the geological model and reservoir description to the final analysis of recovery factor optimizations. In petroleum engineering area, numerical reservoir simulators ...

  • Ab Initio Density Study of N and O Coadsorption on Pt(100) and Pt(111) 

    Obodo, Tobechukwu Joshua (2009-11-13)
    We have used ab initio density functional theory to study the coadsorption of N and O on Pt(100) and Pt(111) surfaces. Our calculations show that on Pt(100) the most favourable site is the hollow site for N and the bridge ...

  • AB Initio Study of Surface Energy, Surface Stress and Coupling Coefficient of Au (111) 

    Shehu, Mustapha (AUST, 2023-12-10)
    This study investigates ab initio exploration of the Au (111) surface within the generalized gradient approximation, with a primary focus on assessing the convergence properties of this noble metal. An in-depth analysis ...

  • Abelian quotients of mapping class groups of highly connected manifolds 

    Galatius, Søren; Randal-Williams, Oscar (SpringerMathematische Annalen, 2015-10-12)
    We compute the abelianisations of the mapping class groups of the manifolds W²ⁿ_g = g(Sⁿ × Sⁿ) for n ≥ 3 and g ≥ 5. The answer is a direct sum of two parts. The first part arises from the action of the mapping class group ...
