  • Aslanyan, V. K.; Mishuris, Gennady; Hudak, Y. I.; Aslanyan, A. G. (Mnemozina Publisher, Moscow, 2009)
  • Wood, Ian (2007-04)
    We consider the Laplacian with Dirichlet or Neumann boundary conditions on bounded Lipschitz domains Ω, both with the following two domains of definition: D1(Δ)={u∈W1,p(Ω):Δu∈Lp(Ω), Bu=0} , or D2(Δ)={u∈W2,p(Ω):Bu=0} , where ...
  • Langstaff, David (2002-04-01)
    Various position sensitive readout systems for microchannel plates are considered. A discrete anode detector with 192 channels and integrated data acquisition electronics developed at the University of Wales, Aberystwyth ...
  • Schultz, R. A.; Watters, T. R.; Cook, Anthony; Robinson, M. S. (2002-06)
    Insight into the mechanical and thermal structure of Mercury's early lithosphere has been obtained from forward modeling of the largest lobate scarp known on the planet. Our modeling indicates the structure overlies a ...
  • Greaves, G. N. (Royal Society of Chemistry, 2007-11-01)
  • Bayat, Abolfazl; Burgarth, Daniel Klaus; Mancini, Stefano; Bose, Sougato (2008-05-22)
    We investigate the multiple use of a ferromagnetic spin chain for quantum and classical communications without resetting. We find that the memory of the state transmitted during the first use makes the spin chain a ...
  • Cox, Simon; Weaire, Denis; Bradley, G. (2001)
    A model is developed to describe the formation of metallic foams in which liquid drainage acts to collapse the foam before it can freeze. Numerical solution of the foam drainage equation, combined with the equations of ...
  • Sazio, P. J. A.; Amezcua-Correa, A.; Finlayson, C. E. (2006-03-17)
    Deposition of semiconductors and metals from chemical precursors onto planar substrates is a well-developed science and technology for microelectronics. Optical fibers are an established platform for both communications ...
  • Cox, S. J.; Flikkema, E. (2010-04-27)
    Candidates to the least perimeter partition of various polygonal shapes into N planar connected equal-area regions are calculated for N ≤ 42, compared to partitions of the disc, and discussed in the context of the energetic ...
  • Cox, Simon (2006-08-30)
    Two-dimensional bidisperse foams were simulated in cyclic, uniaxial, extensional shear. Mixing of bubbles of different sizes only occurs at high strains, and once mixed, the bubbles do not segregate. For liquid fractions ...
  • Piccolroaz, Andrea; Movchan, Natasha; Movchan, Alexander; Mishuris, Gennady (2012-10-31)
    We consider the quasi-static propagation of a Mode III crack along the interface in a bimaterial plane containing a finite array of small line defects (microcracks and rigid line inclusions). The microdefects are arranged ...
  • Radi, Enrico; Mishuris, Gennady; Piccolroaz, Andrea (2012-05-14)
    In this paper we are concerned with the problem of a crack lying at the interface between dissimilar materials with microstructure undergoing antiplane deformations. The micropolar behaviour of the materials is described ...
  • Pintér, Balázs; Vo, H.; Thom, S.; Balthazor, R. L. (American Geophysical Union, 2006)
    We report on a modeling study on the effects of subauroral polarization stream (SAPS) events equatorward of the plasmapause footprints, using the Sheffield Coupled Thermosphere-Ionosphere-Plasmasphere (CTIP) model. SAPS ...
  • Balthazor, R. L.; Pintér, Balázs; Thom, S. D.; Vo, H.; Bailey, G. J. (2006-10)
    We report on a modeling study on the effects of subauroral polarization stream (SAPS) events equatorward of the plasmapause footprints, using the Sheffield Coupled Thermosphere-Ionosphere-Plasmasphere (CTIP) model. SAPS ...
  • Laurson, L.; Mughal, A.; Serpico, C.; Durin, G.; Zapperi, S. (2011)
    We study the effect of disorder and temperature on the field-driven dynamics of a transverse domain wall occurring in thin and narrow magnetic strips made of a soft magnetic material such as permalloy. Motivated by a ...
  • Laurson, Lasse; Mughal, Adil; Durin, G.; Zapperi, Stefano (2010-12-31)
    We present a line-based model of transverse domain walls in thin magnetic strips, to study the effect of bulk disorder on the domain wall dynamics within the thermally activated creep regime. The creep velocity is found ...
  • Oechsner, Andreas; Mishuris, Gennady (2009-01)
    The gas pressure built up within closed cells of porous or cellular metals influences the macroscopic behaviour during deformation. Another important process affected by internal pore pressure is the roll forming of ...
  • Channon, Kevin J.; Devlin, Glyn L.; Magennis, Steven W.; Finlayson, Christopher Edward; Tickler, Anna K.; Silva, Carlos; MacPhee, Cait E. (2008-04-23)
    We describe the formation of self-assembling nanoscale fibrillar aggregates from a hybrid system comprising a short polypeptide conjugated to the fluorophore fluorene. The fibrils are typically unbranched, similar to 7 nm ...
  • Evans, Andrew; Vearey-Roberts, Alex R. (2005-02-10)
    Control of the interfacial potential barrier for metal/n-GaAs diodes has been achieved using thin interlayers of the organic semiconductor, tin phthalocyanine (SnPc). The I-V characteristics for organic-modified Ag/S:GaAs ...
  • Spahn, P.; Finlayson, C. E.; Etah, W. Mbi; Snoswell, David R. E.; Baumberg, J. J.; Hellmann, G. P. (2011-05-16)
    Synthetic opals, based on self-assembled arrays of core-shell (bead/matrix) polymer microspheres, are a promising platform for next-generation photonic structures, coatings and sensors. The refractive index contrast (Delta ...
