    Technical Report 2013-05
    This report presents three reference architectures that can be used as architectural blueprints for applications of three different system classes. The first system class comprises applications in the field of energy management; the second one contains applications in the domain of desktop grid computing; the third system class contains multi-user multi-display applications. Because applications in the scope of energy management are safety-critical and desktop grid computing applications have to cope with a variety of self-interested participants, applications of these domains have in common that they can increase their robustness and efficiency by considering the trustworthiness of participants. Multi-user multi-display applications have to assess the social relationships between its users and adapt based on trustworthiness facets such as transparency and controllability. Therefore, the reference architectures given here are based on a multi-agent system that provides functionality for the utilization of trust. Experiences with participants can be stored and evaluated so that trust can be derived and incorporated into the applications. Additionally, the platform provides the basis for open systems in which agents enter and leave dynamically.
