  • Gohm, Rolf (Springer Basel, 2012-11-07)
    To a pair of subspaces wandering with respect to a row isometry we associate a transfer function which in general is multi-Toeplitz and in interesting special cases is multi-analytic. Then we describe in an expository way ...
  • Jones, Sian Angharad; Cox, Simon (2011-08-31)
    A two-dimensional foam consists of a monolayer of bubbles. It can be created by squeezing the more familiar three-dimensional foam between two parallel glass plates. We describe and explain the minimum plate separation H ...
  • Weaire, D.; Cox, Simon; Fátima Vaz, M. (2002-04)
    Small cells in an experimental sample of two-dimensional foam, such as that which is contained between two glass plates, may undergo a transition to a three-dimensional form, becoming detached from one boundary. We present ...
  • Li, Xing (2003-07-04)
    It is assumed that magnetic flux tubes are strongly concentrated at the boundaries of supergranule convection cells. A power law spectrum of high frequency Alfvén waves with a spectral index -1 originating from the sun is ...
  • Mishuris, Gennady; Miszuris, Wiktoria; Öchsner, Andreas (2009-03)
    Imperfect transmission conditions modelling a thin reactive intermediate layer between two bonded materials in a dissimilar strip are derived in this paper in most general case extending results obtained previously. The ...
  • Jones, Sian; Dollet, B.; Slosse, N.; Jiang, Yi; Cox, Simon; Graner, François (2011-05-05)
    The flow of a quasi-two-dimensional foam through a constriction is described. The bubble velocity and elongation (texture) is compared between two sets of experiments and two different quasi-static simulations using Surface ...
  • Greaves, G. N.; Catlow, C. R. A.; Derbyshire, G. E.; McMahon, M. I.; Nelmes, R. J.; Van der Lann, G. (2008-11-01)
    After over a quarter of a century, the doors of the world's first synchrotron radiation source have closed. Its contribution to materials science in the past and the future should not be underestimated.
  • Douglas, Robert J.; Burton, G. R. (2003-05)
    This paper proves some results concerning the polar factorisation of an integrable vector-valued function $u$ into the composition $u = u^{\#} \circ s$, where $u^{\#}$ is equal almost everywhere to the gradient of a convex ...
  • Mavron, V. C.; McDonough, Thomas P.; Key, Jennifer D. (2009-01)
    We show that a construction described in [K.L. Clark, J.D. Key, M.J. de Resmini, Dual codes of translation planes, European J. Combinatorics 23 (2002) 529–538] of small-weight words in the dual codes of finite translation ...
  • Mishuris, Gennady; Dronka, J.; Aslanyan, A. G.; Selsil, O. (2007)
    The objective of the paper is to study the vibrations of 1D-3D nondegenerate multistructures, which are partly damaged. Such an analysis is useful to quickly asses the condition of a structure which has been in use over a ...
  • Mishuris, Gennady; Alexandrov, Sergei (2007-01)
    Viscoplastic models including a saturation stress are considered. The existence of the saturation stress significantly changes the mathematical structure of solutions near maximum friction surfaces (surfaces where the ...
  • Cox, Simon (2005-08)
    An implementation of the recent viscous froth model of Kern et al. [N.Kern, D.Weaire, A. Martin, S. Hutzler, S.J. Cox, The two-dimensional viscous froth model for foam dynamics, Phys. Rev. E 70 (2004) 041411.] in the Surface ...
  • Cox, Simon John; Mishuris, Gennady; Weaire, Denis (2009-08-08)
    The steady-state solutions of the viscous froth model for foam dynamics are analysed and shown to be of finite extent or to asymptote to straight lines. In the high-velocity limit, the solutions consist of straight lines ...
  • Garel, E.; Mege, D.; Lagabrielle, Y.; Cook, Anthony (2003-05)
    A large fraction of surface extension on Mars occurred at segmented grabens having width/length ratios akin to oceanic rifts on Earth. Association with volcanic landforms such as pit craters clearly suggests interconnection ...
  • Mishuris, Gennady; Movchan, A. B.; Slepyan, L. I. (2007)
    We analyze a crack propagating in an inhomogeneous rectangular lattice in the state of anti-plane shear. The filtering properties of such a lattice are linked to the energy dissipation due to waves initiated by the crack. ...
  • Lanagan, Gareth Daniel Edward (Aberystwyth UniversityMathematical and Physical Sciences, 2012)
  • Evans, Dafydd Gwion; Sims, Aidan (2012-07-01)
    We investigate the question: when is a higher-rank graph C*-algebra approximately finite dimensional? We prove that the absence of an appropriate higher-rank analogue of a cycle is necessary. We show that it is not in ...
  • Wilding, Martin C.; Wilson, Mark; McMillan, Paul F. (2005-02-15)
    Supercooled liquids in the Y2O3-Al2O3 system undergo a liquid–liquid phase transition between a high–temperature, high–density amorphous (HDA) polymorph form and one with lower density (LDA form) that is stable at lower ...
  • Raufaste, Christophe; Dollet, Benjamin; Cox, Simon; Jiang, Yi; Graner, François (2007-06)
    We study the two-dimensional flow of foams around a circular obstacle within a long channel. In experiments, we confine the foam between liquid and glass surfaces. In simulations, we use a deterministic software, the Surface ...
  • Hoydalsvik, Kristin; Barnardo, Twilight; Winter, Rudolf; Haas, Sylvio; Tatchev, Dragomir; Hoell, Armin (2010-09-20)
    The morphology of sol–gel derived dip-coated yttria-doped zirconia films containing variable amounts of yttria has been studied using in situ grazing-incidence small-angle X-ray scattering (GISAXS) whilst heated incrementally ...
