  • The magnetic structure of a coronal X-ray bright point 
    Golub, Leon; Brown, Daniel; DeLuca, Ed; McMullen, Rebecca; Parnell, Clare (2001)
    Abstract. X-ray bright points are small dynamic loop structures that are observed all over the solar corona. The high spatial and temporal resolution of the TRACE instrument allows bright points to be studied in much greater ...
  • Magnus effect and dynamics of a spinning disc in a rarefied medium 
    Mishuris, G.; Plakhov, A. (2009)
    Magnus effect consists in deflection of the trajectory of a rotating body moving in a gas. It is a direct consequence of the interaction between the body surface and the gas particles. In this paper, we study the so-called ...
  • Mathematical and Numerical Modelling of Confectionery Manufacture 
    Bowers, Gemma (Aberystwyth University, 2005)
    This thesis involves the mathematical and numerical study of several model problems related to the industrial manufacture of the confectionery product known as "Chewits". As the name suggests, this product is a soft, ...
  • Mathematics, it is easy 
    Aslanyan, V. K.; Mishuris, Gennady; Hudak, Y. I.; Aslanyan, A. G. (Mnemozina Publisher, Moscow, 2009)
  • Maximal L p -regularity for the Laplacian on Lipschitz domains 
    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 ...
  • An MCP based detector array with integrated electronics 
    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 ...
  • The mechanical and thermal structure of Mercury's early lithosphere 
    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 ...
  • Melting and Amorphisation 
    Greaves, G. N. (Royal Society of Chemistry, 2007-11-01)
  • Memory Effects in spin-chain channels for information transmission 
    Bayat, Abolfazl; Burgarth, Daniel; Mancini, Stefano; Bose, Sougato (2008)
    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 ...
  • Metallic foam processing from the liquid state 
    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 ...
  • Microstructured Optical Fibers as High-pressure Microfluidic Reactors 
    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 ...
  • The minimal perimeter for N confined deformable bubbles of equal area 
    Cox, Simon; Flikkema, Edwin (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 ...
  • The mixing of bubbles in two-dimensional bidisperse foams under extensional shear 
    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 ...
  • Mode III crack propagation in a bimaterial plane driven by a channel of small line defects 
    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 ...
  • Mode III interfacial crack in the presence of couple stress elastic materials 
    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 ...
  • Modeling subauroral polarization streams equatorward of the plasmapause footprints 
    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 ...
  • Modeling subauroral polarization streams equatorward of the plasmapause footprints 
    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 ...
  • Modelling domain wall dynamics in thin magnetic strips with disorder, 
    Laurson, L.; Mughal, A.; Zapperi, S.; Durin, G. (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 ...
  • Modelling of the multiaxial elasto-plastic behaviour of porous metals with internal gas pressure 
    Oechsner, Andreas; Mishuris, G. (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 ...
  • Modification of fluorophore photophysics through peptide-driven self-assembly 
    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 ...
