Information technology supports efficient operations, enterprise integration, and seamless
value delivery, yet itself is too often inefficient, un-integrated, and of unclear value. This …

Presently, there is no satisfactory model for dealing with political autonomy of agents in
policy based management. A theory of atomic policy units called 'promises' is therefore …

A method is proposed whereby values for Service Level Objectives (SLOs) of an SLA can be
chosen to reduce the sum IT infrastructure cost plus business financial loss. Business …

We investigate the relevance of time ordering in the definition of off-diagonal parton
distributions in terms of products of fields. The method we use easily allows determination of …

Distributed host-based anomaly detection has not yet proven practical due to the excessive
computational overhead during training and detection. This paper considers an efficient …

Abstract The QoS attributes of Grid services play important roles in several tasks in Grid
computing such as QoS-aware service composition, service negotiation, resource …

Mobile ad hoc networks (MANET) rely on the cooperation of all the participating nodes. The
Cooperation requires detecting routes and forwarding packets. However, it consumes …

Relationships between objects constitute our notion of space. When these relationships
change we interpret this as the passage of time. Observer interpretations are essential to the …

We describe a model of computer security that applies results from the statistical properties
of graphs to human-computer systems. The model attempts to determine a safe threshold of …

We use the notion of a promise to define local trust between agents possessing autonomous
decision-making. An agent is trustworthy if it is expected that it will keep a promise. This …
