BACKGROUND There is a lack of research investigating organised activity participation and associated alcohol use in vulnerable groups. AIMS The purpose of this research was to test and compare associations between participation in organised activities and indicators of hazardous drinking between young offenders and young non-offenders. METHODS Two groups of 13-18 year-old males were recruit...

This paper describes some possible uses of Formal Concept Analysis in the detection and monitoring of Organised Crime. After describing FCA and its mathematical basis, the paper suggests, with some simple examples, ways in which FCA and some of its related disciplines can be applied to this problem domain. In particular, the paper proposes FCA-based approaches for finding multiple instances of ...

This work shows potentials for rapid self-organisation of sensor networks where nodes collaborate to relay messages to a common data collecting unit (sink node). The study problem is, in the sense of graph theory, to find a shortest path tree spanning a weighted graph. This is a well-studied problem where for example Dijkstra’s algorithm provides a solution for non-negative edge weights. The pr...

Several data-centric communication paradigms have been proposed in the domain of Wireless Sensor Networks (WSN). Therefore, the principles of operation and maintenance in such networks are changing to control massively distributed systems. Previous addressing schemes fail or produce too much overhead if only locally unique addresses of sensor nodes are required. In this paper, we present a dyna...

In this paper we survey the architecture and AI aspects in our project on early warningand intrusion detection based on combined AI methods. We address the problem of alarm assessment in intrusion detection and use plan reconstruction based on hierarchically organised procedural knowledge that contains descriptions of adversary actions. Reconstructed plans are supposed to correlate events and a...

The benefit of endovascular treatment (ET) after acute ischemic stroke has long been debated. Recent studies have demonstrated the clinical benefit of ET up to approximately 8 hours after stroke onset, mainly in association with intranenous thrombolysis. The positive effect is higher if ET is initiated early and performed by an experienced team. Current ET techniques include thrombectomy with c...

Besides their topological properties, Kohonen maps are often used for vector quantization only. These auto-organised networks are often compared to other standard and/or adaptive vector quantization methods, and, according to the large literature on the subject, show either better or worst properties in terms of quantization, speed of convergence, approximation of probability densities, cluster...
