The past few years have seen a rise in the popularity of the use of mentalistic attitudes such as beliefs desires and intentions to de scribe intelligent agents Many of the models which formalise such attitudes do not admit degrees of belief desire and intention We see this as an understandable simpli cation but as a simpli cation which means that the re sulting systems cannot take account of m...

Group-communication applications are a very promising opportunity for developing valuable MANET-based applications. However, real-world experimental studies are required to indicate the best solutions to implement them. We have implemented a real prototype in which alternative networking stacks can be used to support a distributed Whiteboard application. By means of experimental results we show...

Separation of concerns is a fundamental principle for managing conplex tasks. Previous tools for assisting in generating back-of-the-book indexes do not apply this principle as thoroughly as they might; in particular, most confuse two issues: recording where references occur in the main text, and deciding what terms should appear in the index. This paper describes a general facility for multi-l...

A Model of Protozoan Movement for Artificial Life. Alan Dorin, Justin Martin Department of Computer Science, Monash University, Clayton, 3168, Australia. e-mail: aland or justinm @bruce.cs.monash.edu.au Perhaps the most important aspect of modelling Artificial Life for computer animation is the accurate portrayal of motion. We introduce a method for the modelling and locomotion of Life based on...

In th.is paper, we d~scribe a method for the computation of the optical flow in a sequence of images acq~Ired by a. mo~mg camera. The method is guided by the simultaneous satisfaction of two opposIte constramts mtroduced by the regularization process used to remove the underdetermination related to the aperture phenomenon. Two cooperative Kalman filters are used which allow us to compute the mo...

During the last few years, the proliferation of miniaturised devices with networking capabilities has provided the technological grounds for pervasive networking environments. It is not visionary to foresee a world of pervasive devices embedded in the environment interacting between them, and with those carried by users, via wireless communications. In addition, fostered by the diffusion of sma...

In this article, I analyse how the Shepherd of Hermas constructs an ancient Christian reading culture through concurrent portrayals reading, copying and book production. argue that, by portraying its protagonist as idealised reader, scribe auditor, early that authenticates Hermas's role prophet, activates textual dissemination ritualises practice auditory ‘reading’. The article closes with ‘Her...
