The bosonic vertex operator algebra on a genus g Riemann surface
Tuite, Michael P.; Zuevsky, Alexander (201108)We discuss the partition function for the Heisenberg vertex operator algebra on a genus g Riemann surface formed by sewing handles to a Riemann sphere. In particular, it is shown how the partition can be computed by means ... 
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 axioms of ... 
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 ... 
Elastic interface acoustic waves in twinned crystals
Destrade, Michel (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 ... 
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 ... 
Learning with Consistency between Inductive Functions and Kernels
Yang, Haixuan (2009)[no abstract available] 
NHDC and PHDC: Nonpropagating 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, Nonpropagating Heat Diffusion Classifier (NHDC) and Propagating Heat Diffusion ... 
Nonlinear correction to the Euler buckling formula for compressed cylinders with guidedguided end conditions
Destrade, Michel (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 ... 
On the application of robust numerical methods to a complete flow wavecurrent model. Boundary and Interior Layers ONERA
Madden, Niall (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 ... 
Partition functions and chiral algebras.
Tuite, Michael P. (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
Yang, Haixuan (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
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 ... 
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. ... 
Seminonnegative matrix factorization with global statistical consistency for collaborative filtering
Yang, Haixuan (2009)[no abstract available] 
Sorec: social recommendation using probabilistic matrix factorization
Yang, Haixuan (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 ... 
Strain rate effects on the failure characteristics of excised human skin
Destrade, Michel (The 9th International Conference on the Mechanics of Time Dependent Materials, 2014)Skin is a complex, multilayered material which exhibits nonlinear, anisotropic and viscoelastic behaviour. Its structure is complex and can be broadly divided into three main layers: the epidermis, the dermis and ...
