A Multimodal Acoustic Tool for Inline Pipe Inspection 3/19/2018 The US energy transport pipeline system is a longstanding distribution network with most of its still standing pipes being installed between the 1950s–1970s. Due to degradation mechanisms, such as embrittlement, capable of causing a two-fold reduction in fracture toughness, pipe rupture is a major risk. Current nondestructive ins ...

Proposal title: Rapid Assessment of Air Void System in Fresh Concrete Water expansion during freeze-thaw cycles can cause deterioration in concrete, leading to scaling, cracking, and crumbling over a period of years. Resistance to this damage is achieved with a system of voids formed by adding surfactants to the fresh concrete to stabilize air bubbles naturally entrained during mixing. The volume ...

Proposal title: Broken Rail Detection from Flashing Rear End Device Broken rails are a common cause of mainline derailments and a particular concern given the increasing use of our rail system for passenger traffic and petroleum products. The progressive nature of the defects provides an opportunity for early detection of cracks before they become significant enough to cause a derailment. Unfortu ...

This proposed activity will conduct case studies of six selected United States ports to determine whether an integrated terminal information system in each of them might deliver significant benefits to port operators, port users, and shippers. Using the experience of the railroad industry as a guide, problems and possibilities for integrating information flow will be examined. The final report w ...

THE FEASIBILITY OF BUILDING A PERSONAL COMPUTER MODEL OF THEEVACUATION PROCESS WILL BE STUDIED, USING AN EXPERIMENTAL MODEL DEVELOPED BY GOURARY ASSOCIATES INC. THE RESULTING MODEL WILL PERMIT THE STUDY AND VISUALIZATION OF PASSENGER MOVEMENTS DURING EVACUATION. IT WILL ALSO ALLOW THE STUDY OF THE EFFECTS OF CROWDING, FIRE, OBSTRUCTIONS, AND OTHER EFFECTS DURING THE EVACUATION PROCESS. THE MODEL W ...

ADHESIVES CURRENTLYUSED ON AIRPORT PAVEMTNS FOR LIGHTING /ELECTRICAL INSTALLATIONS HAVE DIFICIENCIES, AND INNOVATIVE USE OF OTHER ADHESIVE COMPOUNDS, OR MATERIALS, THAT WOULD PROVIDE IMPROVED PALCEMENT QUALITIES, AND INCREASED ADHESIONCHARATERISTICS WITH ASPHALTIC MATERIALS IS NEEDED. THIS PROPOSED PROGRAM WOULD AID IN DEFINING THE PROBLEM QUANTITATIVELY, ESTABLISH PERFORMANCE CRITERIA FOR THE ADH ...

THERE DOES NOT EXIST TODAY A UNIFIED MEANS OF EVALUATING THE VORTEX INTENSITY BEHIND COMMERCIAL JET LINERS PRIOR TO PROTOTYPE DEVELOPMENT AND TESTING AT FULLSCALE. OVER THE PAST SEVERAL YEARS, DATA AND ANALYTICAL DEVELOPMENTS HAVE PROVIDED MUCH ADDITIONAL TECHNOLOGY WHICH MAY MAKE POSSIBLE THE PREDICTION OF WAKE INTENSITY AND DECAY FROM FIRST PRINCIPLES. THE OBJECT OF THIS INVESTIGATION IS TO DEMO ...

UNDER IFR CONDITIONS, AIRPORT CAPACITY IS CURRENTLY LIMITED BY FAA SEPARATION STANDARDS BETWEEN AIRCRAFT. THESE STANDARDS ARE SET TO AVOID A LANDING ENCOUNTER WITH A VORTEX WAKE. IF AN ONBOARD VORTEX SENSOR AN ESCAPE SYSTEM COULD BE DEVELOPED WHICH IS BOTH RELIABLE AND INEXPENSIVE, THE A AVIATION COMMUNITY COULD BENEFIT BY DECREASED TERMINAL DELAYS WITHOUT COMPROMISING SAFETY. THE CONCEPT TO BE ST ...

A SIX MONTH PROGRAM TO DEVELOP A RUGGED NEW DEVICE FOR MONITORING THE ONSET OF ICE FORMATION ON SURFACES OF TRANSPORTATION VEHICLES, ROADS, BRIDGES AND AIRCRAFTS, WILL BE DEVELOPED AND A PROTOTYPE WILL BE LABORATORY TESTED. THE NOVEL GAGE AND ELECTRONIC SYSTEM IS PARTLY BASED ON THE TECHNOLOGY APPLIED TO MEASURE CONDUCTIVITY OF SOLUTIONS. BASED ON EXISTING TECHNOLOGY, AND ALREADY TESTED UNDER HIGH ...
