Mobile networks need additionnal security functions in contrast to traditional xed-topology static-user networks. In fact, a new problem involving mobility is that users are able to access the network at multiple points which can be separated by signiicant geographic distances and many diierent administrative boundaries. As these access points are not necessarily under the control of a single a...

Norway has always been a multilingual society; Sami languages have spoken in vast geographical areas since prehistoric times, the Kven and other historical minority groups settled count...

Years after the initial development of the current routing protocols we still lack an understanding of the impact of various parameters on the routes chosen in today’s Internet. Network operators are struggling to optimize their routing, but the effectiveness of those efforts is limited. In this article, we study sensitivity of routing stretch and diversity metrics to factors such as policies, ...

A relatively new avenue of Web-based information retrieval research, intended to semantically improve information extraction, is the idea of using geographical information to accurately locate resources. This paper introduces a technique for locating sound and music files geographically. It uses information extracted from the Web relating to audio resources and combines it with geospatial locat...

It is a well-established result that the marginal probability of a social tie between two persons declines with geographical distance for a wide range of social relations (see, e.g., Bossard, 1932; Zipf, 1949; Festinger et al., 1950; Hägerstrand, 1967; Freeman et al., 1988; Latané et al., 1995; McPherson et al., 2001). While often regarded as a mere curiosity, others have argued that this relat...

VAST 2013 Mini-Challenge 1 was a rolling competition in which participants would submit a set of weekly predictions for movie revenue and viewer rating. This was a closed world contest in which contestants were provided with a set of Twitter indices, bitly links, and access to the Internet Movie Database. In order to facilitate these predictions, we have created a web-deployable system that com...

Economies of agglomeration are central to the understanding of the emergence of industrial clustering. However, existing models that incorporate such agglomeration economies have been largely neglecting the vast amount of empirical evidence on inter-sectoral differences in the patterns of industrial concentration. In this paper, we propose a baseline model of firm location in presence of dynami...
