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)
To increase the assurance with which agents can be deployed in operational settings, we have been developing the KAoS policy and domain services. In conjunction with Nomads strong mobility and safe execution features, KAoS services and tools allow for the specification, management, conflict resolution, and enforcement of DAML-based policies within the(More)
Information visualization has been a research topic for many years, leading to a mature field where guidelines and practices are well established. Knowledge visualization, in contrast, is a relatively new area of research that has received more attention recently due to the interest from the business community in Knowledge Management. In this paper we(More)

This paper introduces a version of KAoS Semantic Policy and Domain Services that has been developed to support Web Services-based (i.e., OGSA-compliant) Grid Computing Architectures. While initially oriented to the dynamic and complex requirements of software agent applications, KAoS services are now being extended to work equally well with both agent and(More)
This paper summarizes our efforts to bring together and extend the best in current theory and technologies for teamwork-centered autonomy for space applications. Traditional planning technologies at the foundation of intelligent robotic systems typically take an autonomy-centered approach, with representations, mechanisms, and algorithms that have been(More)
Coordination is an essential ingredient of joint activity in human-agent-robot teams. In this paper, we discuss some of the challenges and requirements for successful coordination, and briefly how we have used KAoS HART services framework to support coordination in a multi-team human-robot field exercise.
The purpose of this study was to determine whether a 4-week isotonic resistance training program using Theraband elastic tubing and lightweight dumbbells would significantly increase concentric shoulder rotator strength or velocity of serve or both in a group of elite-level tennis players. Twenty-two male and female varsity college tennis players were(More)

Description-logic-based knowledge representations and reasoning methods are being used increasingly as the basis for semantically-rich software services. Using such representations and reasoning methods in comprehensive applications is among one of the best ways to identify and understand gaps and limitations. KAoS domain and policy services, which rely(More)
Complex services in Service-Oriented Architectures such as the Grid typically require to be configured in multiple ways that cannot be anticipated by service designers; we illustrate this requirement by studying the myGrid registry, a Grid Registry capable of supporting annotations of service descriptions by third-party users. Instead, services have to be(More)
