Each robot uses a layered architecture for real-time situation assessment and decision making, inspired by the Thinking Cap and the Saphira architectures. Context-dependent blending simplifies the integration of higher-level, symbolic deliberation processes and lower level, and numeric control processes. Basic behaviors, as well as the blending mechanism, are implemented using fuzzy logic techniques for coping with uncertainty. A reactive planner is used to generate directions to the lower level about the activation of behaviors.

Firstly, we introduce a conceptual framework for characterizing systemic coordination at different levels abstraction. Secondly, challenges and opportunities of this framework is outlined as a matter of exploiting a Service-oriented layered architecture for communicating entities (SOLACE) in combination with a particular coordination model (TuCSoN). In the context of systems engineering, we consider SOLACE and TuCSoN to be examples of the basic tools required for support of systemic coordination, i.e., the continuous process of construction and observation of open computational systems and their evolving interaction space. Finally, we outline the impact of these tools on empirical aspects of systemic coordination. M. Fredriksson and R. Gustavsson are affiliated with the

The foremost challenge with this class of systems is that of automated sustainability, i.e., online assertion of systemic qualities. To that end, we introduce the application domain of trustworthy and sustainable operations in marine environments and our experience of applicable models in experimenting with quality of service in network-centric warfare. Finally, we conclude the paper with a discussion regarding challenges in the domain of open computational systems.

The system developed addressed qualities such as information fusion, target acquisition, and selforganization in open computational systems; comprised of distributed services. As such, the system prototype executes on a service-oriented layered architecture for communicating entities (SOLACE) and, furthermore, different perspectives of the prototype are visualized by means of a distributed interaction system for complex entity relation networks (DISCERN).

Through our own experiments in the fields of imitation learning and intelligent agents, it became clear that the lack of a unified, powerful yet intuitive API was a serious impediment to the adoption of commercial games in both research and education. Parallel to our own specialised work, we therefore decided to develop a generalpurpose library for the creation of game agents, in the hope that the availability of such software would help stimulate further interest in the field. Though geared towards machinelearning, the API would be flexible enough to facilitate multiple forms of artificial intelligence, making it suitable for application in research and in undergraduate courses centring upon traditional AI and agent-based systems.

The involved information systems can be comprised by a wide range of complex, interacting, and proactive services. Consequently, construction and observation of complex multiagent systems is an important issue to pursue. We argue that methodological principles of the involved systems most appropriately can be dealt with in ...

We take its realization further towards practice by presenting simple new schemes that provide benefits over previous ones in terms of scalability, performance and security. Our first contribution is a simple, practical, scalable scheme called SKIE-OT that achieves the best possible security in their framework. SKIE-OT is based on the Boneh-Franklin identity-based encryption (IBE) scheme [10] and exploits algebraic properties of the latter. We also show that the role of identity-based encryption is not coincidental by proving that IBE is equivalent to (not strongly) key-insulated encryption with optimal threshold and allowing random-access key updates.

At first only interfacing and behavior, but recently both CORBA and OLE has included functionality such as automation and events. However, providing for these properties are not enough since they only map onto a subset of the required set of properties. 2 What we are facing is a plethora of definitions on the term FRPSRQHQW. The definition I make use of at this point is characterized as a four level infrastructure [25], used by one of the most complete component technology of today -OMG's COR-BA technology, consisting of an object bus, object services, object facilities, and various components of different shapes. 3UREOHP 'HVFULSWLRQ
