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 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 ...

ABSTRACT:The Air Force has a need to maintain strong intelligence capability in semi-permissive and anti-access area denial (A2/AD) scenarios where full-motion video (FMV)-based surveillance assets are rare or unavailable. In such environments, priority is given to leveraging any and all other sources of intelligence available, which may include ?open sources? of data available on the public Web, ...

ABSTRACT: Advanced Cooling Technologies, Inc. (ACT) proposes to develop a Liquid Desiccant (LD) based Air Washer (AW) by utilizing Vortical-flow, Direct-contact Mass Exchanger (VDMX) technology recently developed by ACT. This system is based on principles similar to conventional Liquid Desiccant Air Conditioning systems (LDAC), such as falling film or porous wheel, but with the added capability ...

ABSTRACT:The Arnold Engineering Development Complex (AEDC) represents the nations largest aerospace ground test facilities and includes several wind tunnels that are unlike any other in the world.AEDC routinely provides aerodynamic and aerothermodynamic ground testing to evaluate aerodynamic and propulsion system performance under hypersonic conditions.Its facilities are used to test the flight an ...

ABSTRACT: This proposal describes an analytical approach to model rolling element bearings for gas turbines and similar drive systems. Detailed approaches for modeling bearing material fatigue life, bearing heat generation, and tribology are presented. The resulting analytical bearing code will enable gas turbine engineers and designers to better assess engine lubrication system thermal loads a ...

This project will achieve a mobile application called SleepFit that enables users to track their sleep habits and receive feedback that promotes positive behavior change to improve sleep quality. The SleepFit app will: (1) unobtrusively collect accurate s

Lightning protection is crucial for atmospheric flight of any missile vehicle. The direct and indirect effects of lightning can easily cause catastrophic failure of a missile due to structural breach, fuel vapor ignition, damage to electronics, etc. While the indirect effects of lightning must still be addressed, with aluminum skin, if it is of sufficient thickness, the electrical energy will be ...
