  • Mishuris, G.; Movchan, A.; Slepyan, L. I. (Springer, 2009)
    This review paper outlines several formulations for lattice structures where dynamic lattice Green's functions play an important role in analysis of localization near defects as well as fracture in structured media. The ...
  • Mishuris, Gennady; Movchan, Alexander B.; Slepyan, Leonid I. (2009-12)
    We consider a Mode III lattice with an interface layer where the dynamic crack growth is caused by a localised sinusoidal wave. In the wave–fracture scenario, the ‘feeding wave’ (here also called the knife wave) delivers ...
  • Johnson, Judd; Arndt, Martina Belz; Morgan, Huw; Daw, Adrian; Mickey, Don; Habbal, Shadia Rifai; Jaeggli, Sarah; Kuhn, Jeff (2007-07)
    The first image of the full solar corona in the Fe XI 789.2 nm spectral line, acquired during the total solar eclipse of 29 March 2006, with a sequence of 7, 2 and 0.5 second exposures, revealed a surprisingly extended ...
  • Heule, Rahel; Bruder, Christoph; Burgarth, Daniel; Stojanović, Vladimir M. (2010)
    Motivated by some recent results of quantum control theory, we discuss the feasibility of local operator control in arrays of interacting qubits modeled as isotropic Heisenberg spin chains. Acting on one of the end spins, ...
  • Evans, David Andrew; Vearey-Roberts, Alex R.; Poolton, Nigel Robert (2006-10-17)
    Cubic and hexagonal phases of boron nitride (c-BN and h-BN) have been identified and located using optically detected x-ray absorption spectroscopy (ODXAS). Each phase was identified by distinct resonance features in the ...
  • Carter, James Andrew (Aberystwyth UniversityMathematical and Physical Sciences, 2013)
    Abstract What is the composition of the surface of the Moon? This investigation aims to map the abundances of some of the main rock-forming elements over the surface of the Moon. Accurately determining the ...
  • Palermo, Vincenzo; Schwartz, Erik; Finlayson, Christopher Edward; Liscio, Andrea; Otten, Matthijs B. J.; Trapani, Sara; Müllen, Klaus; Beljonne, David; Friend, Richard H.; Notle, Roeland J. M.; Rowan, Alan E.; Samori, Paolo (2010-02)
    The optimization of the electronic properties of molecular materials based on optically or electrically active organic building blocks requires a fine-tuning of their self-assembly properties at surfaces. Such a fine-tuning ...
  • Golub, Leon; Brown, Daniel; DeLuca, Ed; McMullen, Rebecca; Parnell, Clare (2001)
    Abstract. X-ray bright points are small dynamic loop structures that are observed all over the solar corona. The high spatial and temporal resolution of the TRACE instrument allows bright points to be studied in much greater ...
  • Mishuris, Gennady; Plakhov, Alexander (2009)
    Magnus effect consists in deflection of the trajectory of a rotating body moving in a gas. It is a direct consequence of the interaction between the body surface and the gas particles. In this paper, we study the so-called ...
  • Bowers, Gemma (Aberystwyth University, 2005)
    This thesis involves the mathematical and numerical study of several model problems related to the industrial manufacture of the confectionery product known as "Chewits". As the name suggests, this product is a soft, ...
  • Vellender, Adam (Aberystwyth UniversityMathematical and Physical Sciences, 2013)
    Abstract The main aim of this thesis is to generalise weight function techniques to tackle crack problems in bi-material linearly elastic and isotropic solids with imperfect interfaces. Our approach makes extensive use ...
  • Aslanyan, V. K.; Mishuris, Gennady; Hudak, Y. I.; Aslanyan, A. G. (Mnemozina Publisher, Moscow, 2009)
  • 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 ...
  • Greaves, G. N. (Royal Society of Chemistry, 2007-11-01)
  • Bayat, Abolfazl; Burgarth, Daniel Klaus; Mancini, Stefano; Bose, Sougato (2008-05-22)
    We investigate the multiple use of a ferromagnetic spin chain for quantum and classical communications without resetting. We find that the memory of the state transmitted during the first use makes the spin chain a ...
  • Cox, Simon; Weaire, Denis; Bradley, G. (2001)
    A model is developed to describe the formation of metallic foams in which liquid drainage acts to collapse the foam before it can freeze. Numerical solution of the foam drainage equation, combined with the equations of ...
  • Sazio, P. J. A.; Amezcua-Correa, A.; Finlayson, C. E. (2006-03-17)
    Deposition of semiconductors and metals from chemical precursors onto planar substrates is a well-developed science and technology for microelectronics. Optical fibers are an established platform for both communications ...
  • Cox, S. J.; Flikkema, E. (2010-04-27)
    Candidates to the least perimeter partition of various polygonal shapes into N planar connected equal-area regions are calculated for N ≤ 42, compared to partitions of the disc, and discussed in the context of the energetic ...
