There is a growing need for the evaluation and certification of distributed systems regarding security standards. Almost all existing multi-agent systems that have been developed in the context of the telecommunications market neglect strong security evaluations. In particular, an evaluation of a multi-agent system based on the widely accepted and well(More)
This paper describes the agent framework JIAC IV, and the various projects it has been applied in. The projects were industry-funded as well as research-oriented. Our aim is to convey the particular requirements that followed from this link, and the consequences for the further development of the framework. We describe the projects and the impact that JIAC(More)
While mobile devices are becoming more and more powerful, the number of potential security threats is increasing. Although the important role of users in the realization of IT security measures is widely acknowledged and documented, research in the area of mobile security mostly concentrates on technical means. In this work we take the first step in(More)
In this paper a real time obstacle detection system for robots is presented. The technique is based on a single camera and no further sensors or encoders are required. The algorithm is independent of geometry and even moving objects can be detected. The system provides a top view map of the robotpsilas field of view in real-time. First, the images are(More)
Mobile Endgeräte werden immer leistungsfähiger und damit wächst für die Nutzer auch das Gefahrenpotenzial durch typische IT-Sicherheitsbedrohungen. Obwohl die Verantwortung des Benutzers für die Einhaltung der IT-Sicherheit anerkannt und wissenschaftlich belegt ist, konzentriert sich die Forschung zur IT-Sicherheit im mobilen Umfeld meistens auf die(More)
We examined if entertainment-robots should use emotions. In an experiment we presented jokes to participants to find out if different emotions have different effects on their pleasure. We found out that emotions do have an impact on userspsila perceptions when using entertainment robots.
Humans can have many different motives, e.g. pleasure and challenge, to play games. Rapidly evolving technologies in mobile devices have opened a new category of mobile gaming, e.g. by directly integrating motion sensors into the mobile devices. We have examined a few new technologies and what kind of motivation can be created by them.
