  • 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 ...
  • 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 ...

  • Langstaff, David; Chase, Thomas Robert (Elsevier, 2007-04)
    A one dimensional detector array using MCP technology in conjunction with a custom ASIC is presented. The ASIC features 768 pixels, each 3mm in length on a pitch of 25µm, giving a length in the dispersive direction of 19.2 ...

  • Winter, Rudolf; Smith, I. H.; Jones, Aled R.; Greaves, G. N. (2005)
    The glass-forming reactions between sodium carbonate (Na2CO3) and silica (SiO2) have been investigated by 23Na, 29Si, and 13C magic-angle spinning (MAS) NMR spectroscopy. The multinuclear MAS NMR approach identifies and ...

  • Poolton, Nigel; Evans, D. A.; Hamilton, B.; Towlson, B. M. (2006-05)
    The design and use of a novel portable synchrotron end-station is described, that allows for the micro-imaging of X-ray absorption features of solids, via their luminescence emission. This mode of measurement is possible ...

  • Plakhov, A. Y.; Torres, D. (2005-06-01)
    The problem of minimum resistance is studied for a body moving with constant velocity in a rarefied medium of chaotically moving point particles in the Euclidean space . The distribution of the velocities of the particles ...

  • Gohm, Rolf (2010-04-01)
    We study a model of repeated interaction between quantum systems which can be thought of as a non-commutative Markov chain. It is shown that there exists an outgoing Cuntz scattering system associated to this model which ...
  • Kummerer, B.; Gohm, Rolf; Lang, T. (2006)
    We give a non-commutative generalization of classical symbolic coding in the presence of a synchronizing word. This is done by a scattering theoretical approach. Classically, the existence of a synchronizing word turns out ...

  • Title, Alan; Carolus, Thomas; Shine, Richard; Wolfson, C. Jacob; Nightingale, Richard; Schrijver, Carolus; Brown, Daniel; Alexander, David (2003)
    Recent observations from TRACE in the photospheric white light channel have shown sunspots that rotate up to 200° about their umbral centre over a period of 3-5 days. The corresponding loops in the coronal fan are often ...
  • Kellett, B.; Dunkin, S. K.; Grande, Manuel (2001)
    Mercury is the little known innermost terrestrial planet. A number of significant questions remain unanswered. We describe areas in which a compact imaging X-ray spectrometer could make a valuable contribution. It can ...
