  • Edges of Mutually Non-dominating Sets 

    Everson, Richard M.; Walker, David J.; Fieldsend, Jonathan E. (ACM, 2013-07)
    Multi-objective optimisation yields an estimated Pareto front of mutually non-dominating solutions, but with more than three objectives understanding the relationships between solutions is challenging. Natural solutions ...
  • Effect of heterogeneity on the elastic properties of auxetic materials 

    Gaspar, N.; Smith, Christopher W.; Evans, Kenneth E. (American Institute of Physics, 2003)
    Auxetic materials are gaining practical interest for their unusual and sometimes extreme mechanical response. The process of modeling these materials so far has highlighted a number of microstructural properties that are ...
  • The effect of thermal anisotropies during crystallization in phase-change recording media 

    Belmont, M. R.; Aziz, Mustafa M.; Wright, C. David (American Institute of Physics, 2008)
    The problem discussed is the significance of anisotropies in the thermal parameters of different phases of phase-change materials as used for data storage purposes during recording. The particular phase change in interest ...
  • The effects of low impact development on urban flooding under different rainfall characteristics 

    Qin, Hua-peng; Li, Zhuo-xi; Fu, Guangtao (Elsevier, 2013)
    Low impact development (LID) is generally regarded as a more sustainable solution for urban stormwater management than conventional urban drainage systems. However, its effects on urban flooding at a scale of urban drainage ...
  • Efficiency droop in InSb/AlInSb quantum-well light-emitting diodes 

    Nash, G.R.; Mirza, B.I. (American Institute of Physics (AIP), 2013)
    Efficiency droop in InSb/AlxIn1−xSb quantum-well light-emitting diodes has been investigated as a function of temperature for devices containing 20 nm, 40 nm, and 100 nm wide quantum well active regions. The amount of droop ...
