Ranking Pages by Topology and Popularity within Web Sites
Jose Borges, Mark Levene
We compare two link analysis ranking methods of web pages in a site. The first, called Site Rank, is an adaptation of PageRank to the granularity of a web site and the second, call…
The Spectra of Lamplighter Groups and Cayley Machines
Mark Kambites, Pedro V. Silva, Benjamin Steinberg
We calculate the spectra and spectral measures associated to random walks on restricted wreath products of finite groups with the infinite cyclic group, by calculating the Kesten-v…
Statistics of infections with diversity in the pathogenicity
F. Guinea, V. A. A. Jansen, N. Stollenwerk
The statistics of outbreaks in a model for the propagation of meningococcal diseases is analyzed, taking into account the possibility that the population is fragmented into weakly…
Statistical stability of saddle-node arcs
Vitor Araujo, Maria Jose' Pacifico
We study the dynamics of generic unfoldings of saddle-node circle local diffeomorphisms from the measure theoretical point of view, obtaining statistical stability results for dete…
A Dynamic Clustering-Based Markov Model for Web Usage Mining
José Borges, Mark Levene
Markov models have been widely utilized for modelling user web navigation behaviour. In this work we propose a dynamic clustering-based method to increase a Markov model's accuracy…
Ageing in the critical contact process: a Monte Carlo study
Jose J. Ramasco, Malte Henkel, Maria Augusta Santos +1
The long-time dynamics of the critical contact process which is brought suddenly out of an uncorrelated initial state undergoes ageing in close analogy with quenched magnetic syste…
