  • Benmore, C. J.; Weber, J. K. R.; Wilding, M. C.; Du, J.; Parise, J. B. (2010-12-07)
    X-ray diffraction measurements performed on aerodynamically levitated CaSiO(3) droplets have been interpreted using a structurally heterogeneous liquid-state model. When cooled, the high-temperature liquid shows evidence ...
  • Burrows, Keiran (Aberystwyth UniversityMathematical and Physical Sciences, 2014)
    Abstract Ring Diagram Analysis (RDA) is one of the cornerstones of local ...
  • Vickers, Martin (Aberystwyth UniversityMathematical and Physical Sciences, 2013)
    High resolution satellite imagery is more readily available and in larger quantities than ever before. It has become increasingly di cult for researchers in the planetary science community to manually analyse all of these ...
  • Cox, Simon; Graner, François (2004)
    We consider three-dimensional clusters of equal-volume bubbles packed around a central bubble and calculate their energy and optimal shape. We obtain the surface area and bubble pressures to improve on existing growth laws ...
  • Cook, A. C. (2011-03-07)
    This abstract investigates whether there is an obvious correlation between transient lunar phenomena and Earth tides on the Moon, as has been claimed in past publications. Aristarchus Crater observations are used in this study.
  • Maclean, Rhona; Beveridge, Colin; Longcope, Dana; Brown, Daniel; Priest, Eric (2005-07-08)
    The magnetic breakout model gives an elegant explanation for the onset of an eruptive solar flare, involving magnetic reconnection at a coronal null point which leads to initially enclosed flux 'breaking out' to large ...
  • Cox, Simon; Kafer, J.; Rabaud, D.; Quilliet, C.; Graner, François; Ataei Talebi, S. (2008)
    A 2D foam can be characterised by its distribution of bubble areas, and of number of sides. Both distributions have an average and a width (standard deviation). There are therefore at least two very different ways to ...
  • Brown, Daniel; Priest, Eric (2001-02-03)
    Many traditional two-dimensional models of flares and other reconnective events rely on an X-point in the corona which collapses to form a current sheet where reconnection takes place. However, the Sun's corona is ...
  • Weaire, Denis; Cox, Simon; Vaz, M. Fatima (2003)
    Experiments on a small cluster of bubbles in a nominally two-dimensional foam show an instability in which a topological change forces one of the bubbles to be ejected to the outside of the cluster at ap oint where this ...
  • Wyn, Aled (Aberystwyth UniversityMathematical and Physical Sciences, 2009)
    This thesis concerns the response of two-dimensional foams to applied shear based on numerical simulations in the quasistatic limit. The effect of liquid fraction and areadisorder on the discrete topological changes (T1s) ...
  • Massiot, D.; Jones, Aled R.; Florian, Pierre; Winter, Rudolf (2005-02)
    The kinetics of the reaction of batches of powdered quartz and sodium carbonate was studied by in situ 23Na nuclear magnetic resonance (NMR) spectroscopy using a laser-heated probe. We show for the first time that the ...
  • 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 ...
