Abstract: Integrated sensor and media modeling environment has been developed to simulate subsurface sensing systems and environmental parameters relevant to the subsurface sensing modalities. The modeling environment is designed ...

Abstract: A model that applies to initial bridge load ratings based on allowable stress, load factor, and load and resistance factor design is presented. The prognostic component calculates bridge load ratings probabilistically ...

Abstract: This paper presents a probabilistic model of the load rating process incorporated with field inspection observations applied to a prestressed concrete bridge to capture deterioration characteristics. The main computational ...

Abstract: A new error function is introduced to use natural frequencies and associated mode shapes measured at a selected subset of degrees of freedom for stiffness and mass parameter estimation at the element level. The incomplete ...

Abstract: The StreetScan pavement-management system (PMS) is introduced. It empowers cities to make more cost-effective road repair decisions. At the heart of the system is a vehicle outfitted with a patented, multimodal sensor array ...
