NDT of Fracture Toughness for Pipeline Steels 3/16/2018 Ultrasound-based technology to nondestructively determine fracture toughness of pipeline steels will be developed. Fracture toughness is the material parameter that, along with applied loading and flaw geometry, dictates the critical crack size, and therefore controls the flaw size that must be detected during inspections. A major challeng ...

TECHNICAL ABSTRACT: We propose developing a new observational capability for measuring upper atmosphere (20-Km to 200-Km+ altitude) wind and temperature dynamics, based on Doppler imaging of Limb concentrations of NO, N2O, and CO2 called the Doppler Wind Temperature Sounder. The principle of operation is that by measuring the Doppler shift of trace gases created by the differential velocity betwee ...

Searching for street parking, a behavior known as cruising for parking, leads to excess congestion and pollution. Many recent smart parking interventions have attempted to address this issue, but the problem of effectively detecting and measuring cruising remains largely unsolved. The goal of this work is to develop methods to detect and measure cruising for parking and its effects on congestion u ...

The Next Generation Equipment Committee (NGEC) developed a standard for specifying the use of an Ethernet based digital train line (DTL) network to replace the COMM line for passenger trains. These specifications are PRIIA 305‐919 Digital Train Line Hardware and PRIIA 305‐920 Digital Train Line Software. The intent Is to eventually allow for the improvement of passenger train control. DTL spec ...

Rail line intrusion events, initiated by dismounted individuals on foot or in vehicles, often result in devastating collisions with a train, with outcomes unfavorably to the intruder. A need exists for a locomotive mounted advanced remote detection system that can autonomously detect and characterize an intruder, at a distance, alerting the operating engineer to take corrective action. Navmar Appl ...

Drivers searching extensively for parking, a behavior known as cruising, leads to excess congestion and pollution. Many smart parking interventions have attempted to address this issue in recent years. However, the problem of effectively detecting and measuring cruising remains largely unsolved. We propose to develop a low cost approach to automatic detection of cruising behavior using dense netwo ...

This project seeks to define the performance requirements for a wireless Digital Train Line (WiDTL) through definition of functionality and performance expected, and translating these into network equipment specifications and architecture that wireless network equipment manufacturers can build towards. The effort will include an in-depth review of wireless technology as it applies to sensitive and ...

Autorack cars transport one of the most valuable commodities – fully assembled Automobiles. Due to the longer and higher profile of an Autorack and the fact that heavy automobiles are loaded on to high deck levels, freight trucks with improved track-to-vehicle dynamics as well as higher speed capabilities are desired in anticipation of higher speed passenger service and shared corridors. Unique ...

This proposal leverages our current DOT-funded SBIR Phase II project developing software to assist truck drivers and companies to fatigue optimize driver scheduling and route planning. This project will build a set of web-services specially designed to provide objective quantitative feedback to truck drivers, dispatchers, and safety managers about fatigue from fatigue stressors common in trucking ...

Welding of HPS70W is well understood when using submerged arc welding (SAW) and shielded metal arc welding (SMAW) techniques. A Welding Advisory Group (WAG) which consisted of technical advisors from the Navy, AISI, and FHWA, major filler metal manufacturers, and steel producers determined the guidelines for welding HPS70W. As a result, comprehensive guidelines and welding procedures exist for SAW ...
