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 ...

The proposed system will be capable of being tube mounted on the 60/81/120mm mortar tubes for the measuring of the barrel elevation and cant angles and will provide a firing solution, elevation and azimuth angle, required to impact the target at the range input by the user. The range to the target can be directly entered by the user, read from a fielded laser range finder (VECTOR, PLRF, etc), or c ...

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 ...

Not Available ORBITEC proposes the development of a Lunar Ice Simulator (LIS). The objective of the research is to create a system that can simulate the physical structure of the lunar ice/dust mixtures to test and demonstrate mechanisms for the mining and processing o

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 ...
