According to a survey completed by NCAT in 2019, as part of the NCHRP 20‐07 project, 36 DOTs (out of 43 responded) consider fatigue cracking as the most common failure mode that the agency wants to address. However, in the same survey, 34 of the DOTs also indicated that fatigue cracking test is not required in their mix design specifications. This is primarily because a simple, practical, and ro ...

The goal of the proposed project is to create Kin-X, a novel software system to generate both rapid and deep intelligence from a wide variety of DNA types by inferring distant kinship relationships between individuals and reconstructing familial pedigrees. Kinship inference and pedigree reconstruction are both computationally intensive processes, and our proposed system is designed to achieve both ...

Most research on scour assessment has traditionally focused on developing best-fit or envelope equations to estimate the maximum scour depths from physical experiments in a laboratory environment. However, obtaining an accurate estimate is always a challenge due to numerous uncertainties in the actual riverine or coastal environment. With advances in new surveying technologies and growing computat ...

This STTR Phase II project proposes development of a statistical relational learning framework for identification of the function of laboratory equipment from imagery. The proposed framework uses semantic reasoning to incorporate evidence from multiple classifiers and feature extractors, domain knowledge, and scene context for scene understanding and labeling. The Phase II effort will focus on dev ...

A newly proposed combination of high-strength weathering steel sheet with Ultra-High Performance Concrete (UHPC) to leverage the benefits of both emerging technologies. The combined system offers benefits over traditional orthotropic steel decks and existing concrete or UHPC deck solutions, both of which offer high up-front costs in fabrication or forming. The resulting composite structure provide ...

Phase II will utilize knowledge gained from phase I work to develop and execute a manufacturing process suitable for producing quantities of 3-D printed discrete circuits for radiation detection systems.  The goal is to support mobile radiation detection system requirements for high voltage, analog amplification, and MCA functionality to produce differential pulse height spectra in time sequence. ...

The objective of this SBIR program is to demonstrate the use of patterned radar‐reflective roadway paint and marking tape to communicate safety messages from roadway infrastructure to vehicles and drivers. NanoSonic will work with transportation engineers in the Virginia Tech Transportation Institute (VTTI) and radar design and system engineers in the Virginia Tech Hume Center. Radar‐reflectiv ...

We propose a multi-step approach to event classification using machine learning based on convolutional neural networks for noise reduction, improved phase picking and combined new and legacy features.

Hazard assessment tools that model the transport and dispersion of Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) materials through urban areas are only as good as the 3D models that inform the physics model. Maintaining accurate, up-to-date 3D models of urban areas is challenging. Even in the commercial world, urban construction and demolition may result in the models created a ...

Echo Ridge proposes to deliver a Hardware-in-the-Loop RF environment emulator with high fidelity scintillation simulation within which propagation models will in real-time accurately simulate a nuclear-disturbed environment for testing MILSATCOM communications links. The emulator will accommodate the attachment of physical devices (MILSATCOM communications link equipment or simulators), and/or mod ...
