The ROCK & ROLL deductive object-oriented database system has been used to develop applications that involve the querying and manipulation of spatial data. The approach to the development of these applications has hitherto required that a suitable set of spatial data types is defined and handed

obtained by the FLAIR and IRPHE groups is presented. These include the effect on wake structure and transition due to bluff body geometry changes and of rocking and rolling of circular cylinders. In particular, the two dimensional wake structures and the order of wake transitions to three

Rock asphalt exists in large quantities in Buton Island, Indonesia, and until late 1990s was used extensively in its natural state as a surfacing layer for existing road pavements. On the other hand, extensive maintenance of the Indonesian road network involves the use of very large quantities

weeks on board the Space Shuttle. Consistent with previous studies, roll tilt perception was overestimated shortly after spaceflight and then recovered with 1–2 days. During dynamic linear acceleration (0.15–0.6 Hz, 61.7 m/s2) perception of translation was also overestimated immediately after flight

Figure 1. Unique Bluetooth devices observed throughout the 8 day festival by 33 proximity-based scanners, with the color intensity corresponding to the number of observations in one hour time windows. The scanners are grouped by stages and scanners at the main stages were deployed on day 4. In this paper we present a study of sensing and analyzing an offline social network of participants at a large-scale music festival (8 days and 130,000+ participants). Spatio-temporal traces of participant mobility and interactions were collected from 33 Bluetooth scanners placed in strategic locations at the festival area to discover Bluetooth-enabled mobile phones carried by the participants. We analyze the data on two lev-els. On the micro level, we use a community detection al-gorithm to reveal a variety of groups formed by the partici-pants. On the macro level, we employ an Infinite Relational Model (IRM) in order to recover the structure of the net-work related to participants ’ music preferences. The obtained structure in the form of clusters of concerts and participants is then interpreted using meta-information about music gen-res, band origins, stages, and dates of the performances. We show that the concerts clusters can be described by one or more of the meta-features, effectively revealing preferences of participants. Finally, we discuss the possibility of employ-ing the described method and techniques for creating user-oriented applications and extending the sensing capabilities during large-scale events by introducing user involvement.

. The Virtual Reality Modelling Language (VRML) is used to publish 3D scenes on the World Wide Web. In this paper, we give a brief account of the development of VRML and discuss its use in the context of scientific visualisation. We pay particular attention to the new features that have been added to the language at version 2.0, and assess these for their utility in sharing visualisations of complex 3D datasets. Chief among the new features is the ability to add behaviour to the scene, and we present a number of examples (garnered from our own work, and scenes which we have discovered on the Web) of dynamic visualisations which make use of these enhancements. Finally, we describe some of the shortcomings which we perceive in VRML 2.0, and indicate ways in which the language could usefully evolve in the future. Introduction The World Wide Web (WWW) has had an enormous impact on the way in which information can be shared between disparate locations. Many factors have contributed to the ...

The task undertaken in this article is to determine the extent of the challenge facing major firms who currently control over 80 % of global sound carrier and publishing revenue in the popular (pop) music industry. The aim is to explain the disorganising effects currently responsible for up to 10% decline in music spending. I focus broadly on universally accessible digital technologies which have raised questions about the future of the industry’s current organisational structure and processes both in terms of input (creation of music products in their commodified form) and output (access and consumption of music products). In short, the enormous profits once enjoyed by the handful of majors from traditional exploitation methods are a thing of the past. It is proposed four separate but interconnected challenges are affecting the highly concentrated status quo. Together, the positive and negative impacts of emerging technologies have created a serious dilemma for the controllers of the industry. I argue interconnected illegitimate and legitimate technological challenges are at play suggesting re-organisation is occurring multidimensionally.
