  • On a question of Serre 

    Rahm, Alexander D. (2012)
    Consider an imaginary quadratic number field Q(root -m), with m a square-free positive integer, and its ring of integers {O} . The Bianchi groups are the groups SL2{O}. Further consider the Borel-Serre compactification [7] ...
  • On anisotropic elasticity and questions concerning its Finite Element implementation 

    Vergori, Luigi; Destrade, Michel; McGarry, Patrick; Ogden, Ray W. (Springer, 2013-05-21)
    We give conditions on the strain-energy function of nonlinear anisotropic hyperelastic materials that ensure compatibility with the classical linear theories of anisotropic elasticity. We uncover the limitations associated ...
  • On deforming a sector of a circular cylindrical tube into an intact tube: Existence, uniqueness, and stability 

    Destrade, Michel (Elsevier, 2010-11)
    Within the context of finite deformation elasticity theory the problem of deforming an open sector of a thick-walled circular cylindrical tube into a complete circular cylindrical tube is analyzed. The analysis provides a ...
  • On Genus Two Riemann Surfaces Formed from Sewn Tori 

    Mason, Geoffrey; Tuite, Michael P. (2006)
    We describe the period matrix and other data on a higher genus Riemann surface in terms of data coming from lower genus surfaces via an explicit sewing procedure. We consider in detail the construction of a genus two Riemann ...
  • On Level One Cuspidal Bianchi Modular Forms 

    Rahm, Alexander D. (2013)
    In this paper, we present the outcome of vast computer calculations, locating several of the very rare instances of level one cuspidal Bianchi modular forms that are not lifts of elliptic modular forms.
  • On magneto-acoustic waves in finitely deformed elastic solids 

    Destrade, Michel (SAGE Journals, 2011)
    In this paper, in the context of the quasi-magnetostatic approximation, we examine incremental motions superimposed on a static finite deformation of a magneto-elastic material in the presence of an applied magnetic field. ...
  • On stress-dependent elastic moduli and wave speeds 

    Destrade, Michel (Oxford Journals, 2012-03-30)
    On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
  • On stress-dependent elastic moduli and wave speeds 

    Destrade, Michel; Ogden, R.W. (Oxford University Press, 2013)
    On the basis of the general non-linear theory of a hyperelastic material with initial stress, initially without consideration of the origin of the initial stress, we determine explicit expressions for the stress-dependent ...
  • On the Abaqus FEA model of finite viscoelasticity 

    Destrade, Michel (American Chemical Society, 2009-05)
    Predictions of the QLV (Quasi-Linear Viscoelastic) constitutive law are compared with those of the ABAQUS viscoelastic model for two simple motions in order to highlight, in particular, their very different dissipation ...
  • On the application of robust numerical methods to a complete flow wave-current model. Boundary and Interior Layers ONERA 

    Madden, Niall (2004)
    We aim to show how parameter-robust numerical method may be employed to solve equations arising in the modelling of wave-current interactions.We present two such models: a complete flow model for wave-current interaction ...
  • On the composition product of saturated fusion systems 

    Park, Sejong (Elsevier, 2011-11)
    We say that a fusion system is the composition product of two subsystems if every morphism can be factored as a morphism in one fusion system followed by a morphism in the other. We establish a relationship between the ...
  • On the rectilinear shear of compressible and incompressible elastic slabs 

    Destrade, Michel (2010)
    We review some pseudo-planar deformations for the equations of incompressible isotropic nonlinear elasticity first introduced in 1985 by Rajagopal and Wineman. We extend this class of deformations to compressible isotropic ...
  • On the third- and fourth-order constants of incompressible isotropic elasticity. 

    Destrade, Michel (Acoustical Society of America, 2010-04-25)
    Consider the constitutive law for an isotropic elastic solid with the strain-energy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stress-strain relation can ...
  • Onset of non-linearity in the elastic bending of blocks 

    Destrade, Michel; Gilchrist, Michael D. (American Society of Mechanical Engineers, 2013-01-25)
    The classical flexure problem of non-linear incompressible elasticity is revisited assuming that the bending angle suffered by the block is specified instead of the usual applied moment. The general moment-bending angle ...
  • Partition functions and chiral algebras. 

    Tuite, Michael P. (American Mathematical Society, 2007-05)
    We discuss recent work of the authors concerning correlation functions and partition functions for free bosons/fermions and the b-c or ghost system. We compare and contrast the nature of the 1-point functions at genus 1, ...
  • Piezoacoustic wave spectra using improved surface impedance matrix: Application to high impedance-contrast layered plates 

    Destrade, Michel (2008)
    Starting from the general modal solutions for a homogeneous layer of arbitrary material and crystalline symmetry, a matrix formalism is developed to establish the semianalytical expressions of the surface impedance matrices ...
  • Piezoelectric Love waves on rotated Y-cut mm2 substrates 

    Destrade, Michel (IEEE, 2006-11)
    Consider a layer consisting of a m3m dielectric crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For an X- or Y-cut of the substrate, a Love wave can ...
  • A point-distribution index and its application to sensor-grouping in wireless sensor networks 

    Yang, Haixuan (ACM, 2006)
    We propose [i], a novel index for evaluation of point-distribution. [i] is the minimum distance etween each pair of points normalized by the average distance between each pair of points. We find that a set of points that ...
  • Predictive random graph ranking on the web 

    Yang, Haixuan (2006)
    The incomplete information about the Web structure causes inaccurate results of various ranking algorithms. In this paper, we propose a solution to this problem by formulating a new framework called, Predictive Random Graph ...
  • Predictive ranking: a novel page ranking approach by estimating the web structure 

    Yang, Haixuan (2005)
    PageRank (PR) is one of the most popular ways to rank web pages. However, as the Web continues to grow in volume, it is becoming more and more difficult to crawl all the available pages. As a result, the page ranks computed ...
