Public transport journey planners support a common decision need, and have become popular especially with the availability of real-time tracking data for trip planning and the travellers’ ubiquitous access to the web. This paper, however, takes a usability perspective. The need for assistance in journey planning will vary depending on factors such as the familiarity of the traveller with the ro...

During summer 2009, the UK experienced one of the highest incidences of H1N1 infection outside of the Americas and Australia. Building on existing research into biosecurity and the spread of infectious disease via the global airline network, this paper explores the biopolitics of public health in the UK through an in-depth empirical analysis of the representation of H1N1 in UK national and regi...

We construct multi-center solutions for charged, dilatonic, non-extremal black holes in D = 4. When an infinite array of such non-extremal black holes are aligned periodically along an axis, the configuration becomes independent of this coordinate, which can therefore be used for Kaluza-Klein compactification. This generalises the vertical dimensional reduction procedure to include non-extremal...

We consider the online problem k-CTP, which is the problem to guide a vehicle from some site s to some site t on a road map given by a graph G = (V,E) in which up to k (unknown) edges are blocked by avalanches. An online algorithm learns from a blocked edge when reaching one of its endpoints. Thus, it might have to change its route to the target t up to k times. We show that no deterministic on...
