    • 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 ...
    • Post-buckling development in soft particulate composites 

      Chen, Dean; Xiang, Yuhai; Arora, Nitesh; Yao, Qi; Li, Jian; Rudykh, Stephan (Elsevier, 2023-07-26)
      In this paper, we investigate the post-buckling development of instability-induced patterns in soft particulate composites. Upon reaching the critical strain level, the composite experiences microstructural buckling. ...
    • The Poynting effect 

      Zurlo, Giuseppe; Blackwell, James; Colgan, Niall; Destrade, Michel (American Association of Physics Teachers, 2020-11-19)
      Intuition suggests that twisting a cylinder will shorten it, but here it is shown that for a cylinder of an incompressible material, like rubber, twisting will always produce elongation.
    • Poynting effect of brain matter in torsion 

      Balbi, Valentina; Trotta, Antonia; Destrade, Michel; Annaidh, Aisling Ni (Royal Society of Chemistry, 2019-06-13)
      We investigate experimentally and model theoretically the mechanical behaviour of brain matter in torsion. Using a strain-controlled rheometer, we perform torsion tests on fresh porcine brain samples. We quantify the torque ...
    • 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 ...
    • Prescribing patterns in growing tubular soft matter by initial residual stress 

      Du, Yangkun; Lü, Chaofeng; Liu, Congshan; Han, Zilong; Li, Jian; Chen, Weiqiu; Qu, Shaoxing; Destrade, Michel (Royal Society of Chemistry, 2019-10-02)
      Initial residual stress is omnipresent in biological tissues and soft matter, and can affect growth-induced pattern selection significantly. Here we demonstrate this effect experimentally by letting soft tubes grow in the ...
    • Program quality with pair programming in CS1 

      Krnjaji c, Milovan (2005)
      In several regression applications, a different structural relationship might be anticipated for the higher or lower responses than the average responses. In such cases, quantile regression analysis can uncover important ...
    • Proper formulation of viscous dissipation for nonlinear waves in solids 

      Destrade, Michel (Acoustical Society of America, 2013-03)
      To model nonlinear viscous dissipative motions in solids, acoustical physicists usually add terms the material time derivative of the Lagrangian strain tensor E, to the elastic stress tensor; derived from the expansion to ...
    • Proton resonance frequency shift thermometry: A review of modern clinical practices 

      Blackwell, James; Kraśny, Marcin J.; O'Brien, Aoife; Ashkan, Keyoumars; Galligan, Josette; Destrade, Michel; Colgan, Niall (Wiley, 2020-11-20)
      Magnetic resonance imaging (MRI) has become a popular modality in guiding minimally invasive thermal therapies, due to its advanced, nonionizing, imaging capabilities and its ability to record changes in temperature. A ...
    • Quantifying the Price of Uncertainty in Bayesian Models 

      Krnjajic, Milovan (2013)
      During the exploratory phase of a typical statistical analysis it is natural to look at the data in order to narrow down the scope of the subsequent steps, mainly by selecting a set of families of candidate models ...
    • A quiver presentation for Solomon's descent algebra 

      Pfeiffer, Götz (Elsvier, 2009)
      The descent algebra S(W) is a subalgebra of the group algebra of a finite Coxeter group W, which supports a homomorphism with nilpotent kernel and commutative image in the character ring of W. Thus S(W) is a basic algebra, ...
    • Rational Generalised Moonshine from Abelian Orbifoldings of the Moonshine Module 

      Ivanov, Rossen I.; Tuite, Michael P. (2001)
      We consider orbifoldings of the Moonshine Module with respect to the abelian group generated by a pair of commuting Monster group elements with one of prime order $p=2,3,5,7$ and the other of order $pk$ for $k=1$ or $k$ ...
    • Ray W Ogden: An Appreciation 

      Destrade, Michel; Dorfmann, Luis (SAGE Publications, 2015-07)
      This special issue of Mathematics and Mechanics of Solids is dedicated to Professor Ray Ogden FRS on the occasion of his 70th birthday. It is a companion volume to another special issue edited by our colleagues ...
    • Rayleigh waves and surface stability for Bell materials in compression; comparison with rubber 

      Destrade, Michel (Oxford University Press, 2003)
      The stability of a Bell-constrained half-space in compression is studied. To this end, the propagation of Rayleigh waves on the surface of the material when it is maintained in a static state of triaxial prestrain is ...
    • 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. ...
    • Rayleigh waves in symmetry planes of crystals : explicit secular equations and some explicit wave speeds 

      Destrade, Michel (Elsevier, 2003)
      Rayleigh waves are considered for crystals possessing at least one plane of symmetry. The secular equation is established explicitly for surface waves propagating in any direction of the plane of symmetry, using two different ...
    • Realizing a fusion system by a single finite group 

      Park, Sejong (2010)
      We show that every saturated fusion system can be realized as a full subcategory of the fusion system of a finite group. The result suggests the definition of an 'exoticity index' and raises some other questions which we discuss.
    • A refinement of a conjecture of Quillen 

      Rahm, Alexander D. (Elsevier ScienceDirect, 2015-09)
      We present some new results on the cohomology of a large scope of SL2 groups in degrees above the virtual cohomological dimension, yielding some partial positive results for the Quillen conjecture in rank one. We combine ...
