Non-interference is intended to capture the idea that one user’s interaction with a system should not causally effect any observations of the system that can be made by another user. Thus the latter user should be unable to infer anything from observations of the system about the actual behaviour of the former. As such it is a central concept in security modelling . Ever since Goguen and Mesegu...

In cases where genetic sequence data are collected together with associated physical traits it is natural to want to link patterns observed in the trait values to the underlying genealogy of the individuals. If the traits correspond to specific phenotypes, we may wish to associate specific mutations with changes observed in phenotype distributions, whereas if the traits concern spatial informat...

It is presented a different way for representing documents in information retrieval systems. The relation degree between the index term pairs which describe the document is proposed as the main factor to represent a document. This document representation approach is based on two kinds of different relations between

We present a machine learning approach for estimating missing temporal attributes in genealogical data. Genealogy analyses have been commonly focused on understanding generational relations. The importance of temporal analyses has often been suppresed in genealogical research. We have observed that temporal attributes of an individual, birth, death, marriage and divorce dates, are frequently mi...

Coalescent genealogy samplers attempt to estimate past qualities of a population, such as its size, growth rate, patterns of gene flow or time of divergence from another population, based on samples of molecular data. Genealogy samplers are increasingly popular because of their potential to disentangle complex population histories. In the last decade they have been widely applied to systems ran...

In this paper we consider the genealogy of a random sample of n chromosomes from a panmictic population which has evolved with constant size N over many generations. We address two related problems. First we describe how genealogical information may be usefully partitioned into information on the events (mutations and coalescences) which occur in the genealogy, and the times between these event...
