  • Coronal mass ejections and angular momentum loss in young stars 

    Aarnio, Alicia N.; Stassun, Keivan G.; Matt, Sean P. (Cambridge University Press, 2013)
    In our own solar system, the necessity of understanding space weather is readily evident. Fortunately for Earth, our nearest stellar neighbor is relatively quiet, exhibiting activity levels several orders of magnitude lower ...
  • Correcting the finite-ensemble bias of the ignorance score 

    Siegert, Stefan; Ferro, Christopher A.T.; Stephenson, David B. (Royal Meteorological Society, 2015)

  • Cost-efficient control of wastewater treatment plants to reduce greenhouse gas emissions 

    Sweetapple, Christine; Fu, Guangtao; Butler, David (IWA Publishing, 2014)
    This research investigates the potential of improved wastewater treatment plant control for the cost-efficient reduction of greenhouse gas (GHG) emissions, providing a detailed exploration of the decision variable search ...
  • A counterexample to "positive realness preserving model reduction with ℋ∞ norm error bounds" 

    Guiver, Chris; Opmeer, Mark R. (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    We provide a counterexample to the H∞ error bound for the difference of a positive real transfer function and its positive real balanced truncation stated in “Positive realness preserving model reduction with H∞ norm error ...
  • Countertraveling waves in rotating Rayleigh-Bénard convection. 

    Li, Ligang; Liao, X.; Zhang, Keke (American Physical Society, 2008)
    Linear and nonlinear counter-traveling waves in a fluid-filled annular cylinder with realistic no-slip boundary conditions uniformly heated from below and rotating about a vertical axis are investigated. When the gap of ...
  • Counting molecular-beam grown graphene layers 

    Plaut, Annette S.; Wurstbauer, Ulrich; Pinczuk, Aron; Garcia, Jorge M.; Pfeiffer, Loren N. (American Institute of Physics, 2013)
    We have used the ratio of the integrated intensity of graphene's Raman G peak to that of the silicon substrate's first-order optical phonon peak, accurately to determine the number of graphene layers across our molecular-beam ...
  • Coupled surface plasmon polaritons on thin metal slabs corrugated on both surfaces 

    Hooper, Ian R.; Sambles, J. Roy (American Physical Society, 2004)
    A modelling study of the effect of coupled surface plasmon polaritons (SPPs) on the optical response of a thin metal film corrugated on both surfaces is presented. Initially the case of conformally corrugated metal films ...

    Wedge, S.; Wasey, J. A. E.; Barnes, William L.; Sage, I. (American Institute of Physics, 2004)
    We report strong photoluminescence from a top-emitting organic light-emitting structure where emission takes place through a thin (55 nm) silver film. We show that this emission is mediated via coupled surface plasmon-polariton ...
