This paper describes how a policy-based management system for call control has been generalised and extended, making it applicable to sensor networks and home care networks. The background to these domains is introduced. The previous ACCENT policy system is described, along with the restrictions that previously limited its suitability for other domains. The generalisations needed to the policy ...

The purpose of this note is to describe, in terms of a power series, the distribution function of the exponential functional, taken at some independent exponential time, of a spectrally negative Lévy process ξ = (ξt, t ≥ 0) with unbounded variation. We also derive a Geman-Yor type formula for Asian options prices in a financial market driven by e. Résumé. Loi de la fonctionnelle exponentielle d...

We describe the first-order variations of the angles of Euclidean, spherical or hyperbolic polygons under infinitesimal deformations such that the lengths of the edges do not change. Using this description, we introduce a vector-valued quadratic invariant b on the space of those isometric deformations which, for convex polygons, has a remarkable positivity property. We give two geometric applic...

Limited English proficiency (LEP) affects many Canadians. Patients with LEP are at high risk of medical error, readmission, and increased length stay. We report on the case a 66-year-old male diagnosis glucose-6-phosphate dehydrogenase (G6PD) deficiency associated hemolysis, how language barrier affected his care. Using our as an example, we describe trends in literature inpatient setting, its ...
