Current inspection, maintenance and lifetime estimation practices for composite cylinders have been adopted from earlier NASA research. WavesinSolids LLC are proposing a technological based on an acoustic emission (AE) technique for the in-service testing of composite cylinders. The approach will establish the correlation between AE activity and intensity metrics and the stress intensity factor, a ...

Single chirality of single-walled carbon nanotubes (SWCNTs) is critical for their superb mechanical, thermal, optical and electronic properties. All known methods for producing nanotubes give mixtures of tubes with different chiralities. Physical separation of SWCNT by chirality is thus an enabling step for many potential applications and fundamental studies. The existing anion exchange resins are ...

Prescient Weather proposes four Phase I tasks to increase the value of the new NOAA Climate Forecast System to commercial customers. The capabilities demonstrated and explored in Phase I will be developed and integrated in Phase II as components of a new Seasonal Information and Decision Support System (SIDSS) for our World Climate Service customers. The Phase I tasks are: • Improve season for ...

THE U.S. WEATHER SERVICE PRESENTLY USES A "TIPPING BUCKET" RAIN GAUGE FOR MEASURING RAIN ACCUMULATION. THIS DEVICE IS SENSITIVE TO WIND AND MOTION (AS ON BUOYS), CANNOT MEASURE RAIN RATE, AND REQUIRES FREQUENT MAINTENANCE, BECAUSE OF MOVING PARTS. AN ALTERNATIVE DEVICE IS BEING PROPOSED, WHICH INCORPORATES A RIGID, RESONANT TUBE, CLOSED AT THE TOP BY AN ELECTRO-ACOUSTIC TRANSDUCER, AND AT THE BOTT ...

THE PURPOSE OF THIS RESEARCH PROJECT IS TO DETERMINE THE FEASIBILITY OF MERGING AN EMERGENCY MEDICAL SERVICES (EMS) SIMULATOR WITH GEOGRAPHICAL INFORMATION SYSTEMS (GIS) IN ORDER TO PRODUCE IEMS(3) (INTELLIGENT EMERGENCY MEDICAL SERVICES SYSTEMS SIMULATOR), A PC-BASED SYSTEM WHICH CAN BE USED FOR BOTH ADDRESSING STRATEGIC PLANNING ISSUES OF EMS SYSTEMS (E.G., SYSTEM CONFIGURATION; VEHICLE LOCATION ...

ECOTEK INTERNATIONAL PROPOSES AN ALL SOLID-STATE VISIBILITY MONITORING SYSETM THAT WILL BE USED TO MONITOR VISIBILITY CONDITIONS ALONG ROADWAYS AND WARN TRAVELERS OF LOW VISIBILITY CONDITIONS. THE PURPOSE OF THE SYSTEM IS TO REDUCE THE NUMBER OF MULTIPLE-VEHICLE COLLISIONS AND CONSEQUENT FATALITIES, INJURIES, AND PROPERTY DAMAGES. THE SYSTEM IS BASED ON AN INNOVATIVE APPROACH TO A WELL-ESTABLISHED ...

MSI PROPOSES TO INCORPORATE BACKGROUND SUBSTITUTION OF "FAULTY MODELS" IN CAD DESIGN SIMULATION OF ELECTRONIC CIRCUITS TO PERFORM A "DESIGN OF EXPRIMENTS" DETERMINATION OF SENSITIVITY TO PARAMETRIC VARIATION IN COMPONENTS. THE INFORMATION LEARNED WILL BE USED TO SELECT COMPONENTS THAT WILL HAVE A LONGER LIFE, AND GREATER DURABILITY. THIS FORM OF ANALYSIS COMBINED WITH WORST CASE SENSITIVITY ANALYS ...

GUARDRAIL TERMINALS ARE SOME OF THE MORE TROUBLESOME AND POTENTIALLY HAZARDOUS ROADSIDE APPURTENANCES. RECENTLY DEVELOPED TERMINAL CONCEPTS WHICH HAVE PASSED CURRENT CRASH TEST CRITERIA TEND TO BE EXPENSIVE AND MAY REQUIRE EXCESSIVE LENGTH OF NEED, FLARE-OUT SPACE AND ADDITIONAL FILL AND GRADING. THIS PHASE I SBIR PROPOSAL ADDRESSES THE DEVELOPMENT OF A MORE EFFICIENT ENERGY ABSORBING TERMINAL CON ...

THE FEDERAL AVIATION ADMINISTRATION NEEDS STATISTICAL DATA ON THE X-RAY DAMAGE THRESHOLD OF PHOTOGRAPHIC FILM AND MAGNETIC MEDIA TO PREDICT POSSIBLE DAMAGING EFFECT OF HIGHER POWERED X-RAY FACILITIES BEING CONSIDERED AS PART OF INCREASED AIRPORT SECURITY. TECHNOLOGY DEVELOPMENT ASSOCIATES, INC. (TDA) PROPOSES AN EXPERIMENTAL PROGRAM TO STATISTICALLY EVALUATE DAMAGE THRESHOLDS. X-RAY TRANSPORT ANAL ...
