  • Innes, Davina; Brown, Daniel; Parnell, Clare; Bewsher, Danielle (2005-03-11)
    Blinkers are brightenings at network cell junctions that are traditionally identified with SOHO/CDS and explosive events or high velocity events are identified in high resolution UV spectra obtained from HRTS and SOHO/SUMER. ...
  • Alexandrov, S.; Baranova, I.; Mishuris, Gennady (2008-12-01)
    If the maximal friction law is applied, then some generalizations of the Prandtl solution for the compression of a plastic layer between rough plates do not exist. In particular, this pertains to the viscoplastic solutions ...
  • Wood, Ian; Brown, B. Malcolm; Eastham, M. S. P. (2008)
    The method of singular sequences is used to provide a simple and, in some respects, a more general proof of a known spectral result for leaky wires. The method introduces a new concept of asymptotic straightness.
  • Gohm, Rolf; Skeide, M. (2005-06-02)
    We apply Hilbert module methods to show that normal completely positive maps admit weak tensor dilations. Appealing to a duality between weak tensor dilations and extensions of CP-maps, we get an existence proof for certain ...
  • Anthony; M. J. (IEEE Press, 2006)
    We investigate the use of statistical shape measures for segmented image regions to construct taxonomies of visual similarity. It is demonstrated that without the use of a priori knowledge, cluster analysis can be used to ...
  • Argatov, Ivan; Mishuris, Gennady (2012-05-21)
    A three-dimensional unilateral contact problem for articular cartilage layers is considered in the framework of the biphasic cartilage model. The articular cartilages bonded to subchondral bones are modelled as biphasic ...
  • Sobolev, Andrei; Gough, John E. (2004-03-17)
    We derive the stochastic Schrödinger equation for the limit of continuous weak measurement where the observables monitored are canonical position and momentum. To this end we extend an argument due to Smolianov and Truman ...
  • Phillips, P. M.; Binding, David M.; Philips, T. N. (2006-08-30)
    This paper is concerned primarily with the numerical prediction of the pressure field associated with the flow of an Oldroyd-B fluid through 4:1 contractions, 1:4 expansions and combined 4:1:4 contraction/expansions. ...
  • Heule, Rahel; Bruder, Christoph; Stojanović, Vladimir M.; Burgarth, Daniel (2011-08-31)
    We investigate anisotropic XXZ Heisenberg spin-1/2 chains with control fields acting on one of the end spins, with the aim of exploring local quantum control in arrays of interacting qubits. In this work, which uses a recent ...
  • Cooil, Simon (Aberystwyth UniversityMathematical and Physical Sciences, 2014)
    The Epitaxial nature of graphene growth on the diamond (111) surface has been investigated using real-­‐time photoelectron spectroscopy (REES), Photoemission electron microscopy (PEEM), Angle resolved photoelectron ...
  • Wilding, Martin C.; Benmore, C. J.; Tangeman, J. A.; Sampath, S. (2004-07)
    Glasses made from the magnesium silicate minerals enstatite (MgSiO3) and forsterite (Mg2SiO4) and three intermediate compositions can be considered as analogues of quenched melts from the Earth and Lunar mantle. Combined ...
  • Jones, T. S.; Zahn, D. R.; McGovern, I. T.; Cabailh, G.; Evans, Stephen; Evans, Andrew; Steiner, H. J.; Park, S.; Middleton, R.; Kanpen, T. U.; Evans, David Andrew (2003-09-12)
    The growth of the organic semiconductor CuPc on the InSb(111)A surface at 300 K has been studied using photoelectron spectroscopy. Core level emission data obtained using low energy synchrotron radiation reveal that the ...
  • Chase, Thomas Robert (Aberystwyth UniversityMathematical and Physical Sciences, 2009-01)
    This thesis covers the range of aberrations occurring when an electron counting imaging detector is placed at the focal plane of an electron energy analyser used for photoelectron spectroscopy. The technique of photoelectron ...
  • Wilding, Martin; Guthrie, Malcolm; Kohara, Shinji; Bull, Craig L.; Akola, Jaakko; Tucker, Matt G. (2012-08-22)
  • Wyn, Aled (Engineering and Physical Sciences Research Council, 2008-02-08)
    Here we present a summary, in the form of a table, of the literature concerning the shearing of foams.
  • Mishuris, Gennady; Wrobel, M. (2009-10-26)
    This work deals with a stationary axisymmetrical heat transfer problem in a combined domain. This domain consists of half-space joined with a bounded cylinder. An important feature of the problem is the possible flux ...
  • Nori, Franco; Maruyama, Koji; Burgarth, Daniel (2011-09-26)
    Quantum control requires full knowledge of the system many-body Hamiltonian. In many cases this information is not directly available due to restricted access to the system. Here we show how to indirectly estimate all the ...
  • Slepyan, Leonid I.; Movchan, Alexander B.; Mishuris, Gennady (2010-03-01)
    We consider some structures where the harmonic ‘feeding’ wave localized at the crack faces can force the crack to grow. First, we present some results related to a lattice with a high-contrast layer, where the wave speed ...
  • Linkov, A. M.; Mishuris, Gennady; Fradkin, L.; Dobroskok, A. (2007-07)
    In the current paper crack redirection due to a strategic placing of a heat source in the vicinity of a crack tip is studied. Analysis suggests that for PMMA and considered temperature range the only factor responsible for ...
