concrete bridge deck damage detection by measurement and monitoring variables related to vibration signatures is one of the main tasks of any bridge health monitoring system (bhms). generally damage puts some detectable/discoverable signs in the parameters of bridge vibration behavior. however, differences between frequency and mode shape before and after damage are not remarkable as vibration ...

In this study, a rapid-to-deploy wireless monitoring system is utilized to monitor the vibration response of the 180 meter long Yeondae Bridge, Korea. The bridge consists of a steel box girder section that continuously spans across five supports. Using 20 wireless sensors with MEMS accelerometers interfaced, the wireless monitoring system is installed to measure the bridge response to truck tra...

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 ...

The Junshan Yangtze River Bridge, built in Wuhan, China 2001, is a steel box girder cable-stayed bridge with main span of 460m. Due to decades service, the suffered gradual degradation and some damage. Structural health monitoring has attracted worldwide attention due its capacity structural damage, assisting maintenance management, ensuring safe operation bridges. To monitor performance status...

Summary: using High Performance Computing (HPC) resources in a workflow management systems (WMS) is a powerful way to address eScience challenges such as big data management. We present here WMS4HPC, a WMS connecting bridge with 4 degrees of freedom, for the integration and application of HPC cyberinfrastructure and local resources. The BioExtract Server, a Web-based WMS, has been enhanced to e...
