    Eames, ME; Wood, M; Challenor, Peter G. (-, 2015-12)

  • Comparison of multi-year and reference year building simulations 

    Kershaw, Tristan; Eames, Matthew E.; Coley, David (SAGE Publications, 2010)

  • A comparison of structural and behavioural adaptations to future proofing buildings against higher temperatures 

    Coley, David; Kershaw, Tristan; Eames, Matthew E. (Elsevier, 2012)
    The uncertainty surrounding projections of climate change has left the building design community in a quandary. Should they assume a worst case scenario, and recommend adaptations to designs that might prove to be unnecessary ...
  • Comparison of the effective temperatures, gravities and helium abundances of DAO white dwarfs from Balmer and Lyman line studies

  • Compression or tension? The stress distribution in the proximal femur 

    Rudman, KE; Aspden, RM; Meakin, JR (BioMed Central, 2006-02-20)
    BACKGROUND: Questions regarding the distribution of stress in the proximal human femur have never been adequately resolved. Traditionally, by considering the femur in isolation, it has been believed that the effect of body ...
