This work considers the problem of metamorphosis interpolation between two freeform planar curves. Given two planar parametric curves, the curvature signature of the two curves is linearly blended, yielding a gradual change that is not only smooth but also employs intrinsic curvature shape properties, and hence is highly appealing. In order to be able to employ this curvature blending, we present a constructive scheme to derive curvature signatures of parameter curves. Additionally, we propose a scheme to reconstruct a curve from its curvature signature.

A model of risk assessment was proposed as a debating tool in the interdisciplinary dialogue with wider society. The incorporation of subjective perceptual values into appropriate stage of the risk management process was the basis of the model. The risk epistemology moved away from the suppressive nature of the rationalist and objective paradigm by incorporating relevant social values and issues into the risk model. The assessment of risk that reflected the values of holistic society, led to the breaking of the two way opposition and distrust that existed between the public and risk experts.
Much of the current research in the design of virtual environments is centred on laboratory prototypes and emphasis is placed on supporting cooperation within the virtual world itself. By way of contrast, this paper p...

When working together on a common document, collaborators frequently share and discuss their ideas about further revisions. Collaborative writing might, therefore, be thought of as a process of negotiating what changes to make among co-authors. The World-Wide Web is an easily accessible infrastructure to facilitate such a communication process over documents. This paper explores the dialogues formed by comments exchanged among co-authors in a Web-based collaboration tool, Col/spl middot/laboracio. A case study was performed where a small group of writers discussed and revised a common document, using this system. The author demonstrates how these dialogues are structured and what properties they have in relation to the context of collaborative reviewing processes. The analysis of dialogues is also used to reflect on design issues with regard to dialogue support and comment categorization.
We introduce the concept of variable-consistency monotonic decision tree induced from preference-ordered data concerning a multicriteria sorting (classification) problem. Given the data in form of an information table...

“Team Sweden” is the Swedish national team that entered the Sony legged robot league at the RoboCup2001 competition. The work was distributed over three universities in Sweden. This nationwide character has made the project organization particularly demanding, but has resulted in a rewarding cooperation experience, both scientific and human. The Team identity is as follows: Team Leader: Alessandro Saffiotti (asaffio@***) Team Members: include the authors, plus: R. Johansson (?rebro); P. Davidsson, D. Erman, and J. Kronqvist (Blekinge); J. Carstensen, P. Eklund, P. Larsson, and K. Prorok (Ume?). Sponsors: Swedish KK foundation, Qualisys AB, ?rebro University, Ume? University, and the Blekinge Institute of technology. Team home page: http://***/Living/RoboCup/.
A model for probabilistic independent component subspace analysis is developed and applied to texture description. Experiments show it to perform comparably to a Gaussian model, and to be useful mainly for problems in...

The first six even moments of the displacement of a molecule in water and an atom in liquid argon are found by molecular dynamics simulations and compared with the moments predicted by diffusion theory. We find a noticeable difference between the moments higher than the second. The ratio between predicted and calculated moments approaches unity as 1/t for times larger than 10 ps. Continuous time random walk is used to explain this slow approach of the moments to their diffusion limit.

This paper shows that Statecharts, a high-level specification technique, can be used to represent performance models. This is a powerful technique and is based on state-transition diagrams added with concepts of hierarchy and orthogonality to represent a system behavior. It is shown that Statecharts may conveniently be used to represent models with richness and clarity. Using an analytical approach the technique to determine performance measurements is provided. Three examples are presented and the results show Statecharts’ potential for representing systems for performance evaluation. International Federation of Operational Research Societies 2002.
