Agent-Agent-Communication using FIPA ACL speech acts is a wellknown implementation of ontology based communication. The content of an ACL Message is formulated in FIPA SL content language or one of its sublanguages (SL1, SL2). Yet, validating the semantics of incoming SL encoded messages is a difficult task because SL is undecidable. Therefore, in order to(More)
1. In cats either decerebrated and/or anesthetized by various doses of pentobarbital, the action of pinna stimulation (PS) and other natural somatic or electrical nerve stimuli upon respiration was investigated. For an indication of the state of excitability of the reticular formation the lumbar extensor fusimotor PS-responses were obseve simultaneously. 2.(More)
1. In decerebrate or pentobarbital anesthetized cats the effect of intra-right atrial injection of phenyldiguanide (PDG) upon lumbar fusimotor activity and monosynaptic reflex activity and their responsiveness to pinna stimulation (PS) was investigated. 2. The spontaneous activity of triceps surae muscle spindle afferents or lumbar γ-efferents was in most(More)
CIDOC’s CRM has been introduced as a formal reference ontology with a particular focus on cultural heritage documentation. Meanwhile acknowledged as an ISO standard (21127:2006), one of its main goals is to facilitate interoperability between data and database schemata. In order to take full advantage of CRM’s benefits, an implementation in a modern(More)
Bedingt durch die Komplexitätszunahme im Anwendungsszenario in der Unterhaltungselektronik steigt sowohl die Schwierigkeit als auch das Bedürfnis, die zunehmende Menge an Informationen und neuen Funktionen dem Benutzer auf einfache, komfortable und übersichtliche Weise zugänglich zu machen. Dazu wurde ein Konzept entwickelt, mit dem es möglich ist, ein(More)
Modern distributed systems frequently use autonomous software agents that use ontologies for communication. If each agent owns an ontology as knowledge base and these ontologies change over time, every communication attempt requires merge and revision processes. We discuss visualization possibilities to assist agent developers and researches in(More)
Multi-Agent systems follow a highly abstract programming paradigm. Because of this abstraction level, behaviours of the participants are not always clearly reproducible for humans. In this paper, we present a framework that enables agents to do some introspection and describe themselves. Our approach uses Java annotations and JDI, the Java debugging(More)
