Bridge management officials have expressed a keen interest in the use of low-cost and easy-to-install wireless sensors to record bridge responses during short-term load testing. To illustrate the suitability of wireless sensors for short-term monitoring of highway bridges, a wireless monitoring system is installed upon the Grove Street Bridge to monitor structural responses during static and dy...

This paper introduces a new project, InfraWatch, that demonstrates the many challenges that a large complex data analysis application has to offer in terms of data capture, management, analysis and reporting. The project is concerned with the intelligent monitoring and analysis of large infrastructural projects in the public domain, such as public roads, highways, tunnels and bridges. As a demo...

Multi-context systems (MCS) are a powerful framework for interlinking heterogeneous knowledge sources. They model the flow of information among different reasoning components (called contexts) in a declarative way, using so-called bridge rules, where contexts and bridge rules may be nonmonotonic. We considerably generalize MCS to managed MCS (mMCS): while the original bridge rules can only add ...

Bridge inspection is a pathway to bridge condition rating assessment, and is an essential element of any bridge management system (BMS). The success of a BMS is highly dependent on the quality of bridge inspection outcomes and accurate estimation of future bridge condition ratings. However, existing visual bridge inspection methods suffer several limitations due to human subjective judgment. In...

An integrated ship area network has functionality of remote control and autonomous management of various sensors and instruments embedded or boarded in a ship. For such environment, a wireless bridge is essential to transmit control and/or managing information to sensors or instruments from a central integrated ship area network station. In this paper, one of reliable schemes of WiMedia based w...

Introduction This paper describes a demonstration program Weapons System Open Architecture (WSOA) funded jointly by AFRL, DARPA, and the Open Systems Joint Task Force. WSOA provides an open systems “bridge“ between legacy embedded mission systems and off-board C31 sources and systems. This “bridge” is used to support internetlike connectivity between command and attack nodes. The foundation of ...
