This paper describes a parallel algorithm for selecting activation functionsof an articial network. For checking the eciency of this algorithm a count ofmultiplicative and additive operations is used.[...]

Die bildbasierte automatische Bestimmung der Pose, d. h. der Position und Blickrichtung, einer Kamerain derWelt, ist eine relevante, aber immer noch unzureichend gelöste Aufgabe im Rechnersehen.In dem diesem Bericht zugrunde liegenden Projekt werden höhere markante Merkmale in den...

Conventional security infrastructures in the Internet cannot be directlyadopted to ambient systems, especially if based on short-range communi-cation channels: Personal, mobile devices are used and the participants arepresent during communication, so privacy protection is a crucial issue....

J. Gary Polhills forum paper in this issue was an invitation to try the OWL extension on a model that was written more than a year ago. Download and installation was a matter of a few minutes, extending the old model with a few lines as shown in the paper was not a problem either, visualising...

Social simulation is often described as a multidisciplinary and fast-moving field. This can make it difficult to obtain an overview of the field both for contributing researchers and for outsiders who are interested in social simulation. The Journal for Artificial Societies and Social Simulation...

This short comment on Epstein's (2008) paper and on the response by Thompson and Derr argues that the symmetry between explanation and prediction cannot satisfactorily be discussed without making clear what prediction means - depending on which connotations the authors have with 'prediction'...

This special section includes papers originally presented at a workshop on \'Epistemological Perspectives on Simulation\' in July 2004 at the University of Koblenz, in which some thirty colleagues participated. It had been our impression that there was (and still is) a small, but growing number...

In our paper, we replicate simulation experiments carried out some 30 years ago by Jay M. Anderson who then tried to find out which measures should be taken to avoid the eutrophication of a lake. In his DYNAMO model, he simulated the development of a lake under cultural eutrophication, i.e....
