Cities must perform detailed assessments of sidewalks and streets, including curb ramps, pedestrian signals, crosswalks, street furniture, and other components to determine compliance with the Public Rights-of-Way Accessibility Guidelines. However, current assessment methods are inadequate or unreasonable due to time and resources required. The objectives of this project are to: 1) develop elect ...

The work proposed will provide a demonstration of feasibility and specific design recommendations for building an elevated-temperature resonating crystal balance with nanogram sensitivity. The approach will build upon existing technology commercialized by Masscal for operating a QCM in a temperature-controlled calorimeter. Precise temperature control and new types of crystal sensors will be used t ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

A RAPID FIELD TEST IS PROPOSED TO EVALUATE THE PERMEABILITY OF OPEN-GRADED ROAD BASES AND OTHER DRAINAGE LAYERS. THE SAME TEST ALSO SHOULD BE ADAPTABLE TO EVALUATE PERMEABILITIES OF OTHER EXPOSED PAVEMENT LAYERS INCLUDING THOSE COMPOSED OF BITUMINOUS OR PORTLAND CEMENT CONCRETES, AS AN INDEX TO PERMEATION AND POSSIBLY TO DETERIORATION. IT IS PROPOSED THAT THE PERMEABILITY BE EVALUATED THROUGH USE ...

THE RESEARCH WILL IDENTIFY AND ANALYZE BOTH THE QUANTITATIVEAND QUALITATIVE ASPECTS OF SECURITY CHECKPOINT OPERATIONS. USING INDUSTRIAL ENGINEERING TECHNIQUES, SCREENING OPERATIONS WILL BE BROKEN INTO BASIC ELEMENTS WHICH WILL THEN BE MEASURED AND INVESTIGATED TO DETERMINE THE INTERRELATIONSHIPS BETWEEN SUCH COMPONENTS AS: - PROCESSING RATES - DISTRIBUTION OF PASSENGER ARRIVALS - BOARDING VOLUMES ...

THE PROPOSED PROJECT WILL DETERMINE THE FEASIBILITY OF THE USE OF ADVANCED TYPE II FLUIDS FOR THE DE-ICING/ANTI-ICING OF GENERAL AVIATION (GA) AIRCRAFT WITH TAKEOFF SAFETY SPEEDS (V2) OF GENERALLY LESS THAN 85 KNOTS. TYPE II FLUIDS WILL BE APPLIED TO SEVERAL GA CATEGORY AIRCRAFT. THE ICE PROTECTION CAPABILITY OF THE FLUID WILL BE EVALUATED FOR DIFFERENT FREEZING PRECIPITATION CONDITIONS. THE EFFEC ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

THE SHORTCOMINGS OF THE WIDELY USED BURIED-LOOP VEHICLE DE- TECTOR -- 3 TO 5 YEAR LIFETIME, COSTLY, INCONVENIENT TO MAINTAIN/REPLE, INCOMPATIBLE WITH SOME ROADWAYS, UNRELIABLE ACTIVATION BY SOME VEHICLES -- CAN BE OVERCOME THROUGH THE USE OF OVERHEAD INFRARED VEHICLE DETECTORS. THE TECHNICAL OBJECTIVES OF THE PROPOSED RESEARCH INCLUDE A SURVEY OF APPROPRIATE INFRARED SENSORS AND DEVICE ANALYSIS, D ...

THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A MISSION AND AND ENGINE OIL ANALYSIS BY WHICH TRANSMISSION AND ENGINE WEAROUT CAN BE PREDICTED BY MEASURING OIL TEMPERATURE, CAPACITANCE AND PRESENCE OF HYDROCHLORIC ACID. THIS WILL BE ACCOMPLISHED BY TREATING THE OIL AS A LOSSY DIELECTRIC ACAND PLACING A TRANSDUCER IN THE OIL. BOTH CONDUCTANCE AND SUSCEPTANCE ON APPROPRIATE FREQUENCIES ARE MEASURED AND ...
