Sensor networks face a number of challenges when deployed in unpredictable environments under dynamic, quickly changeable demands, and when shared by many partners, which is often the case in military and security applications. To partially address these challenges, we present a novel target tracking algorithm that can be deployed on various sensor nodes(More)
Perinuclear antineutrophil cytoplasmic antibodies (pANCAs) have previously been demonstrated in patients with various forms of vasculitis and more recently in those with inflammatory bowel disease (IBD) by an indirect immunofluorescence technique. Sera from 194 patients were tested for pANCAs: 101 with ulcerative colitis (43 with varying grades of disease(More)
There is a significant challenge in designing, optimizing, deploying and managing complex sensor networks over heterogeneous communications infrastructures. The ITA Sensor Fabric addresses these challenges in the areas of sensor identification and discovery, sensor access and control, and sensor data consumability, by extending the message bus model(More)
Provenance has been identified as an emerging and important concept within the Grid community for a variety of purposes, such as verifying or tracing results. We seek to provide a concrete conception of provenance and its possible utilisation through the process of designing and implementing a system prototype with some specific provenance requirements.(More)
Service Oriented Architectures (SOA) are increasingly being used by architects of business IT systems to encapsulate key business components and make them available for efficient reuse across multiple business functions. An SOA within a business is typically a managed environment relying on good IT management practice within a reliable networked(More)
The purpose of this document is to propose a logical architecture for a provenance system. The logical architecture is specified independently of specific technologies. Specifically, we introduce our definition of provenance in the context of service-oriented architectures, and we identify the different roles that exist in a provenance system. This document(More)
This paper presents a software architecture for Smart Buildings assets management which enables engineers to receive and update work orders and asset information using augmented reality and mobile technologies. The proposed architecture consists of a layered structure composed of three main modules for Building Management Systems (BMS); data collection,(More)
