Security and Aspects: A Metaobject Protocol Viewpoint

In this paper we reflect upon the results of experiments that have attempted to use Metaobject Protocols to implement security as a crosscutting concern. As security is often cited as a crosscutting concern that could be implemented using Aspects we would like to point the way to some of the requirements that should be met by any aspect language used to implement security as a crosscutting conc...

Viewpoint Quality: Measures and Applications

Several methods that use the notion of viewpoint quality have been recently introduced in different areas of computer graphics, such as scene understanding, exploration of virtual worlds, radiosity and global illumination, image-based rendering and modelling. In this paper, we analyze the behavior of three different viewpoint quality measures. The first one is a heuristic measure, the second on...

Viewpoint quality and global scene exploration strategies

Virtual worlds exploration techniques are used in a wide variety of domains — from graph drawing to robot motion. This paper is dedicated to virtual world exploration techniques which have to help a human being to understand a 3D scene. An improved method of a viewpoint quality estimation is presented in the paper, together with a new method for an automatic 3D scene exploration, based on a vir...

A Network Management Viewpoint on Security in e-Services
