In this paper, we describe our initial implementation of the KAoS policy and domain services. While initially oriented to the dynamic and complex requirements of software agent applications, the services are also being adapted to general-purpose grid computing and web services environments as well. The KAoS services rely on a DAML description-logic-based(More)
Web Services power through explicit representations of Web resources underlying semantics and the development of an intelligent Web infrastructure that can fully exploit them. Semantic Web languages, such as OWL, extend RDF to let users specify ontologies comprising taxonomies of classes and inference rules. Both people and software agents can effectively(More)
In this paper we apply the semantics sketched by Smith and Cohen [11] to the system of conversational policies developed for KAoS [1]. We show that the compositional nature of the speech-acts and their semantics allows us to provide a comprehensive semantics for the conversational policies; and that we can use the generated semantics to analyze policies, to(More)
In this paper we define the concept of conversation policies: declarative specifications that govern communications between software agents using an agent communication language. We discuss the role that conversation policies play in agent communication, and suggest several subtypes of conversation policy. Our reasoning suggests, contrary to current(More)
Policies are being increasingly used for automated system management and controlling the behavior of complex systems, allowing administrators to modify system behavior without changing source code or requiring the consent or cooperation of the components being governed. Past approaches to policy representation have been restrictive in many ways. By way of(More)
The strength of hippocampal synapses can be persistently increased by signals that activate Ca2+/calmodulin-dependent protein kinase II (CaMKII). This CaMKII-dependent long-term potentiation is important for hippocampal learning and memory. In this work we show that CaMKII exhibits an intriguing switch-like activation that likely is important for changes in(More)
NOMADS is a Java-based agent system that supports strong mobility (i.e., the ability to capture and transfer the full execution state of migrating agents) and safe agent execution (i.e., the ability to control resources consumed by agents, facilitating guarantees of quality of service while protecting against denial of service attacks). The NOMADS(More)
The Basic Compact To carry out joint activity, each party effectively enters into a Basic Compact—an agreement (often tacit) to facilitate coordination, work toward shared goals, and prevent breakdowns in team coordination. This Compact involves a commitment to some degree of goal alignment. Typically this entails one or more participants relaxing their own(More)
