  • Elastic interface acoustic waves in twinned crystals 

    Destrade, Michel (Elsevier, 2003)
    A new type of interface acoustic waves (IAW) is presented, for single-crystal orthotropic twins bonded symmetrically along a plane containing only one common crystallographic axis. The effective boundary conditions show ...
  • 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 ...
  • Rayleigh waves in anisotropic crystals rotating about the normal to a symmetry plane 

    Destrade, Michel (American Society of Mechanical Engineers, 2004)
    The propagation of surface acoustic waves in a rotating anisotropic crystal is studied. The crystal is monoclinic and cut along a plane containing the normal to the symmetry plane; this normal is also the axis of rotation. ...
  • NHDC and PHDC: Non-propagating and propagating heat diffusion classifiers 

    Yang, Haixuan (12th International Conference on Neural Information Processing, 2005)
    Abstract - By imitating the way that heat flows in a medium with a geometric structure, we propose two novel classification algorithms, Non-propagating Heat Diffusion Classifier (NHDC) and Propagating Heat Diffusion ...
  • 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 ...
  • Wireless communicative stent for follow-up of abdominal aortic aneurysm, 

    Destrade, Michel (IEEE, 2006)
    An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, which rupture is a life threatening complication. Recent treatment of AAA consists in endovascular treatment with covered stent grafts. ...
  • 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 ...
  • 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 ...
  • Waves and vibrations in a solid of second grade 

    Destrade, Michel; Saccomandi, Giuseppe (World Scientific, 2006)
    We study the viscoelastic second grade solid, for which the constitutive equation consists in the sum of a purely elastic part and a viscoelastic part; this latter part is specified by two microstructural coefficients ...
  • Onde de Love Piézoacoustique 

    Collet, Bernard; Destrade, Michel (2006-04-24)
    Une sélection de résultats analytiques et numériques concernant la propagation d'ondes planes harmoniques guidées dans un bicouche piézoélectrique est présentée. L'étude effectuée concerne les modes transverses horizontaux ...
  • ENDOCOM: Abdominal aortic aneurysm test bench for in vitro simulation 

    Destrade, Michel (IEEE, 2007)
    An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, whose rupture is a life threatening complication. Recent treatment procedures of AAA consists in endovascular treatment with covered ...
  • Diffusionrank: a possible penicillin for web spamming 

    Yang, Haixuan (2007)
    While the PageRank algorithm has proven to be very effective for ranking Web pages, the rank scores of Web pages can be manipulated. To handle the manipulation problem and to cast a new insight on the Web structure, we ...
  • Characteristic classes of complexified bundles 

    Rahm, Alexander D. (Summer School in Algebraic Topology: Sheaf theoretic methods in the theory of characteristic classes, 2007)
    We examine the topological characteristic cohomology classes of complexified vector bundles . In particular, all the classes coming from real vector bundles are computed. We use characteristic classes with the ax-ioms of ...
  • 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, ...
  • Surface stability of nonlinear magnetoelastic solids 

    Ottenio, M.; Destrade, Michel; Ogden, R.W. (Wiley, 2007-12)
    The present paper proposes to identify surface stability when a magnetoelastic half-space is subjected to a pure homogeneous pre-deformation and to a magnetic field normal to its (plane) boundary. Clearly, the aim is to ...
  • Learning latent semantic relations from clickthrough data for query suggestion 

    Yang, Haixuan (2008)
    For a given query raised by a specific user, the Query Suggestion technique aims to recommend relevant queries which potentially suit the information needs of that user. Due to the complexity of the Web structure and the ...
  • Sorec: social recommendation using probabilistic matrix factorization 

    Ma, Hao; Yang, Haixuan; Lyu, Michael R.; King, Irwin (ACM, 2008)
    Data sparsity, scalability and prediction quality have been recognized as the three most crucial challenges that every collaborative filtering algorithm or recommender system confronts. Many existing approaches to recommender ...
  • A note about waves in dissipative and dispersive solids 

    Destrade, Michel; Saccomandi, Giuseppe (World Scientific, 2008)
    We study shear waves propagating in a special viscoelastic model proposed first by Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces the full balance equations to a system of evolution equations ...
  • Finite-amplitude Love waves in a pre-stressed neo-Hookean material 

    Destrade, Michel; Rodrigues Ferreira, Elizabete; Boulanger, Philippe (2008)
    In the context of the non-linear elasticity theory we consider a model for compressible solids called compressible neoHookean material . We show how (exact) finite-amplitude inhomogeneous plane wave solutions and ...
