  • Gunn, Matthew David (Aberystwyth UniversityComputer Science, 2014)
    Summary Mars has been the subject of much interest to science for many hundreds of years. For nearly four decades Landers have been sent to investigate the geology of the Martian surface and search for signs of life. Each ...
  • Davies, I. T.; Cox, Simon (2012-04-04)
    The effect of the interplay between surface tension and gravity on the sedimentation of objects in structured fluids is investigated by simulating the quasi-static motion of a spherical particle through an ordered foam. ...
  • Gough, John Edward; James, Matthew R.; Nurdin, Hendra I. (2010-02-03)
    The aim of this article is to extend linear quantum dynamical network theory to include static Bogoliubov components (such as squeezers). Within this integrated quantum network theory, we provide general methods for cascade ...
  • Wildfeuer, Sebastian (Aberystwyth UniversityMathematical and Physical Sciences, 2013)
    Classical feedback control and system theory are playing an important role in modelling, controlling and analysing complex devices in many branches of engineering. Recent developments like quantum computers and miniaturisation ...
  • Durand, Marc; Kraynik, Andrew M.; Van Swol, Frank; Käfer, Jos; Quilliet, Catherine; Cox, Simon; Ataei Talebi, Shirin; Graner, François (2014-06-19)
    Bubble monolayers are model systems for experiments and simulations of two-dimensional packing problems of deformable objects. We explore the relation between the distributions of the number of bubble sides (topology) and ...
  • Durand, Marc; Kafer, Jos; Quilliet, Catherine; Cox, Simon John; Ataei Talebi, Shirin; Graner, Francois (2012-02-13)
    We propose an analytical model for the statistical mechanics of shuffled two-dimensional foams with moderate bubble size polydispersity. It predicts without any adjustable parameters the correlations between the number of ...
  • Cox, Simon; Weaire, Denis; Hutzler, Stefan; Peron, N. (2007-04)
    We compare extensive experimental results for the gravity-driven steady drainage of oil-in-water emulsions with two theoretical predictions, both based on the assumption of Poiseuille flow. The first is from standard foam ...
  • Movchan, A. B.; Mishuris, Gennady; Movchan, N. V. (2006)
    The aim of the present paper is to analyse the behaviour of the stress and displacement fields in the vicinity of the tip of a crack moving along a bi-material interface. For simplicity, we consider a straight interface ...
  • Mishuris, Gennady; Radi, Enrico; Piccolroaz, Andrea (2012-12)
    This paper is concerned with the problem of a semi-infinite crack steadily propagating in an elastic solid with microstructures subject to antiplane loading applied on the crack surfaces. The loading is moving with the ...
  • Plakhov, A. Y.; Cruz, P. (2004-03)
    We consider the following stochastic approximation algorithm of searching for the zero point x∗ of a function ϕ: xt+1 = xt − γtyt, yt = ϕ(xt) + ξt, where yt are observations of ϕ and ξt is the random noise. The step sizes ...
  • Gough, John E.; Sobolev, Andrei (2004-09)
    We consider an open model possessing a Markovian quantum stochastic limit and derive the limit stochastic Schrodinger equations for the wave function conditioned on indirect observations using only the von Neumann projection ...
  • Davies, Ioan Tudur (Engineering and Physical Sciences Research Council, 2008-02-01)
    One way in which the complex elastic, plastic and viscous properties of a liquid foam can be explored is through the interaction between the foam and an object moving relative to it. This variation on the classic 'Stokes' ...
  • Finlayson, Christopher Edward; Snoswell, David R. E.; Spahn, Peter; Baumberg, Jeremy J. (2011-06)
    Polymer opal photonic-crystal fibers containing self-assembled submicron core-shell particles exhibit stretch-tunable color. These mechanically robust fibers can be produced in an industrially scalable extrusion process.
  • Wilding, Martin C.; Wilson, Mark; McMillan, Paul F. (2006)
    When amorphous materials are compressed their structures are expected to change in response to densification. In some cases, the changes in amorphous structure can be discontinuous and they can even have the character of ...
  • Flikkema, Edwin; Jelfs, Kim E.; Bromley, Stefan T. (2012-12-03)
    The low energy isomer spectrum of hydroxylated silica clusters, (SiO2)M(H2O)N, is investigated using global optimisation with an empirical potential and ab initio structural and energetic refinement. The cases M = 8, 16 ...
  • Wilding, Martin C.; Greaves, G. Neville; Van, Quang Vu; Majérus, Odile; Hennet, Louis (AIP Publishing, 2009)
    Changes in the structure factor of yttria-alumina liquids have been identified in the supercooled range. Different inter-polyhedral configurations between AlO4 and YO6 groups distinguish low density and high density liquid ...
  • Wilding, Martin C.; Benmore, C. J. (2006-01)
    The liquid state dominates terrestrial and planetary processes. The history of the early solar system for example involved the accretion of primarily molten bodies. In cooler temperature regimes, interplanetary dust, comets ...
  • Wilding, Martin Charles; Guthrie, Malcolm; Kohara, Shinji; Bull, Craig L.; Akola, Jaakko; Tucker, Matt G. (2012-06-06)
    The magnesium silicate system is an important geophysical analogue and neutron diffraction data from glasses formed in this system may also provide an initial framework for understanding the structure-dependent properties ...
  • Cristiglio, V.; Hennet, L.; Cuello, G. J.; Pozdnyakova, I.; Johnson, M. R.; Fischer, H. E.; Zanghi, D.; Van, Quang Vu; Wilding, Martin Charles; Greaves, Neville; Price, D. L. (2007)
    We used the aerodynamic levitation technique combined with CO2 laser heating to study the structure of liquid yttrium aluminates above theirmelting point with neutron diffraction. For various yttria contents, we determined ...
  • Whittick, Emma L. (Aberystwyth UniversityMathematical and Physical Sciences, 2010)
    This thesis explores the use of high-latitude electric potential patterns obtained from the Super Dual Auroral Radar Network (SuperDARN) as input to the Coupled Thermosphere Ionosphere Plasmasphere (CTIP) model. By using ...
