In this paper, we present a comprehensive role-based framework for multimedia broadcasts (e.g., for applications such as TV, radio, e-cinema, and e-learning) taking place in a heterogeneous mobile Internet. The added value of the framework is the strong separation between application and network-level roles in combination with support for unrestricted mobility. The framework concentrates on the...

Filming is an analogue process; it requires a mechanical process to record and view, and the source material itself is prone to decay & abrasion [1]. Film is expensive to store, and prohibitively expensive to restore. It is important to note that these problems do not just affect ‘old’ movies; aside from the minority of films that have made use of digital cinema cameras, all previous & most cur...

Define a cubical complex to be a collection of integer-aligned unit cubes in d dimensions. Lebowitz and Mazel (1998) proved that there are between (C1d) and (C2d) complexes containing a fixed cube with connected boundary of (d − 1)volume n. In this paper we narrow these bounds to between (C3d) and (C4d). We also show that there are nn/(2d(d−1))+o(1) connected complexes containing a fixed cube w...

The paper introduces a case study on game journalistic practices and on the construction of historical self-understanding of game cultures. It presents results of the study of Finnish digital game reviews, retrieved from a major computer hobbyist magazine, MikroBitti. The results are based on a qualitative content analysis of 640 reviews from two magazine issues per year (1984–2010). The aim is...

This paper is two-fold. On the one hand, we present a system using qualitative spatial reasoning to help a user choose parts of an image that form interesting objects. The system then allows the user to cut these parts as if unwanted in the original image. On the other hand, we propose a modification of existing texture synthesis methods to create texture in the holes left by the cutting of pre...
