In this paper we describe ARKTOS, a system that uses a Dempster-Shafer rule base to integrate data from multiple sources in order to classify sea ice. ARKTOS analyzes SAR imagery to generate a feature set that describes the image. Next it fuses the SAR-extracted features with digital grid climatology data and sea ice concentration data extracted from SSM/I imagery. The fusion is achieved by a s...

BACKGROUND Methods for comparing hospitals regarding cardiac arrest (CA) outcomes, vital for improving resuscitation performance, rely on data collected by cardiac arrest registries. However, most CA patients are treated at hospitals that do not participate in such registries. This study aimed to determine whether CA risk standardization modeling based on administrative data could perform as we...

This paper describes a proof-of-concept system for detecting insider threats. The system measures insider behavior by observing a user’s processes and threads, information about user mode and kernel mode time, network interface statistics, etc. The system is built using Microsoft’s Windows Management Instrumentation (WMI) implementation of the Web Based Enterprise Management (WBEM) standards. I...

This paper looks at the evolving National Data Infrastructure in Ireland and describes developments to date before considering the emerging Census opportunity. The National Data Infrastructure concept is influenced by the ideas of Svein Nordbotten first introduced in the 1960s and by the representation of three pillars or linked registers (persons, business and property) presented by Lars Thyge...

In ownership-based access control frameworks with the possibility of delegating permissions and administrative rights, chains of delegated accesses will form. There are different ways to treat these delegation chains when revoking rights, which give rise to different revocation schemes. In this paper, we show how IDP – a knowledge base system that integrates technology from ASP, SAT and CP – ca...

Business matching and collaboration support systems are useful, in particular for small-and-medium companies. Most of them developed so far are based on the server-client architecture and provide their services on Web servers. They require special administrative facilities, ask users to upload their data for matching between business needs and seeds, and leave to themselves peer-to-peer communi...
