Characteristic classes of complexified bundles
(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 axioms of ... 
Diffusionrank: a possible penicillin for web spamming
(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 ... 
Elastic interface acoustic waves in twinned crystals
(Elsevier, 2003)A new type of interface acoustic waves (IAW) is presented, for singlecrystal orthotropic twins bonded symmetrically along a plane containing only one common crystallographic axis. The effective boundary conditions show ... 
ENDOCOM: Abdominal aortic aneurysm test bench for in vitro simulation
(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 ... 
Experimental characterisation of neural tissue at collision speeds
(International Research Council on Biomechanics of Injury (IRCOBI), 2012)Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... 
Finiteamplitude Love waves in a prestressed neoHookean material
(2008)In the context of the nonlinear elasticity theory we consider a model for compressible solids called compressible neoHookean material . We show how (exact) finiteamplitude inhomogeneous plane wave solutions and ... 
Hyperelastic and viscoelastic properties of brain tissue in tension
(ASME, 2012)Mechanical characterization of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... 
Learning latent semantic relations from clickthrough data for query suggestion
(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 ... 
Mechanical properties of excised human skin
(Springer Verlag, 2010)In this study we have investigated in influence of location, gender and orientation on the deformation characteristics of 55 samples of human excised skin. Uniaxial tensile tests were carried out at a strain rate of ... 
NHDC and PHDC: Nonpropagating and propagating heat diffusion classifiers
(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, Nonpropagating Heat Diffusion Classifier (NHDC) and Propagating Heat Diffusion ... 
Nonlinear correction to the Euler buckling formula for compressed cylinders with guidedguided end conditions
(Springer, 201102)Euler's celebrated buckling formula gives the critical load N for the buckling of a slender cylindrical column with radius B and length L as N/([pi]^3 B^2 )=(E/4)(B/L)^2, where E is Young's modulus. Its derivation relies ... 
A note about waves in dissipative and dispersive solids
(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 ... 
On the application of robust numerical methods to a complete flow wavecurrent model. Boundary and Interior Layers ONERA
(2004)We aim to show how parameterrobust numerical method may be employed to solve equations arising in the modelling of wavecurrent interactions.We present two such models: a complete flow model for wavecurrent interaction ... 
Onde de Love Piézoacoustique
(20060424)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 ... 
Partition functions and chiral algebras.
(American Mathematical Society, 200705)We discuss recent work of the authors concerning correlation functions and partition functions for free bosons/fermions and the bc or ghost system. We compare and contrast the nature of the 1point functions at genus 1, ... 
A pointdistribution index and its application to sensorgrouping in wireless sensor networks
(ACM, 2006)We propose [i], a novel index for evaluation of pointdistribution. [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
(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
(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 ... 
Rayleigh waves in anisotropic crystals rotating about the normal to a symmetry plane
(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. ...
