This aluminium salt is largely used up to 25% (w/w) in 90% of antiperspirants. Investigations were thus designed to study the neurotoxicity of this ...

However multiple disciplinary teams in different departments and companies often use different systems with different modelling methods and techniques. While the parallelism of this approach can reduce the design life cycle, the complexity of the optimisation problem can lead to difficulties. Agent technology can alleviate some of the difficulties of concurrent design. In this paper, we present an architecture in which agent technology is used to model interactions between design systems, and thereby enable design agents from various design disciplines to explore the design problem and solution space. We also introduce a multiple-evolutionary approach with an automated negotiation mechanism to enable agents to exchange design solutions and to reach an agreed optimised solution for a global design problem.

Autonomous agents representing different organizations need to implement a set of behaviors in addition to their problem solving behaviors in order to facilitate the coordinated exception handling processes across organizational boundaries. In this paper we review the limitations of the current domain independent exception handling approaches and propose a flexible approach to exception handling in MAS. The approach works by incorporating the exception handling services provided by the MAS infrastructure owner and local exception handling mechanism of individual agents. It allows the agent to use system provided exception handling service for all of its protocol related (social) exceptions or use its local exception handling mechanism to deal with a subset of these exceptions. It is claimed that this provides flexibility in exception han...

This paper presents an architectural approach to QoS evaluation and admission control, based on the modelling of both system behaviour and QoS requirements. Two aspects are considered. The first refers to QoS management, and to a component-based architecture for QoS evaluation. The second illustrates the approach with the help of a case study based on a Personal Area Network. The proposed approach is model-based and makes use of models representing both behaviour and QoS aspects of the system via Timed Automata. The compatibility of the mechanism with architectures, which promote QoS management in its own right, such as ITSUMO, is also highlighted.
