THERE IS A NEED FOR A RAPID, NON-DESTRUCTIVE METHOD TO TEST FOR PROPER STEEL PLACEMENT IN PORTLAND CEMENT PAVEMENTS. ISTHE GOAL OF THIS PROPOSED PROGRAM TO DEMONSTRATE THE FEASIBILITY OF USING SHORT-PULSE, GROUND-PENETRATING RADAR AS A MEANS OF RAPID STEEL LOCATION IN CONCRETE PAVEMENT. A GENERAL BACKGROUND IN GROUND-PENETRATING RADAR THEORY IS PRESENTED. LABORATORY AND FIELD MEASUREMENTS USING A ...

In Phase II, Propagation Research Associates, Inc., (PRA) proposes to complete the development of a real-time nowcast of ionospheric scintillation impacts on GPS users. Continuing its partnership with NASA’s Jet Propulsion Laboratory, PRA will implement real-time production of a map of ionospheric scintillation parameters over the United States using real-time data streamed from the National Geo ...

Interference of unburned and activated carbon in fly ash with air-entraining admixtures (AEA’s) in fresh concrete mixtures is a major concern in the concrete industry. Therefore, a rapid and accurate measurement of adsorption capacity of fly ash is of great interest to this industry. In this project, a new method is suggested, which can qualitatively and quantitatively measure different surfact ...

Fairmount Technologies (FT) has demonstrated that ExtruMach is a disruptive technology for drilling curved extrusions and proposes to further develop this during Phase II for milling extrusions. ExtruMach-PoCM (proof of concept machine) is a flow-type multi-axis CNC machine with a small footprint, which is more capable than existing machines in that it has no limit on the length of parts it can ha ...

This proposal provides a detailed account of the Teams work through Phase 1 of the Magnetic Braking and Electric Taxiing SBIR as well as provides a pathway for building and testing a brake system in Phase 2. Having competed the effort of designing the magnetic braking and electric taxiing system in Phase 1, the Team is able to look back and take account the Program goals, accomplishments, and nece ...
