NEUTRON SCATTERING STUDIES HAVE BEEN USUALLY CARRIED OUT USING SINGLE DETECTORS. IN THE LAST FEW YEARS, THE USE OF SPATIALLY RESOLVING DETECTORS HAS RESULTED IN BETTER STATISTICAL ACCURACY WITH SUBSTANTIALLY REDUCED DATA COLLECTIONS TIMES. ALTHOUGH, THE COMMONLY USED NEUTRON DETECTOR ARRAY CONSISTING OF MULITWIRE HE-3 CAMERA IS CAPABLE OF EXCELLENT PHOTONIC BACKGROUND REJECTION, ITS USE IS SEVEREL ...

REGULATIONS GOVERNING THE CONTROL OF PARTICULATE EMISSIONS ARE BECOMING INCREASINGLY STRICT IN TERMS OF THE CONTROL EFFICIENCIES THEY REQUIRE. SEVERAL DRIVING FORCES ARE RESPONSIBLE FOR THIS TREND, FOREMOST OF WHICH IS THE NEED TO CONTROL TOXIC AIR EMISSIONS, SUCH AS TRACE METALS AND HEAVY ORGANIC COMPOUNDS. OTHER DRIVING FORCES INCLUDE THE AMBIENT AIR QUALITY REGULATIONS AND STATE AND LOCAL REG ...

CURRENT SMOKE DETECTION TECHNOLOGIES SUFFER FROM SIGNIFICANT FALSE ALARM RATES. THESE PROBLEMS ARE CURRENTLY BEING ADDRESSED BY REDUCING THE SENSITIVITY OF EXISTING PARTICULATE DETECTORS. IN THIS WORK, THE FEASIBILITY OF A COMBINED PARTICULATE AND CARBON MONOXIDE DETECTOR WILL BE EVALUATED. THE USE OF MULTIPLE FIRE SIGNATURES HAS THE POTENTIAL FOR REDUCING THE FALSE ALARM PROBLEMS WHILE INCREASING ...

THE NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST) HAS UNDERTAKEN AN EFFORT TO PROVIDE SOLID STANDARDS AND ALGORITHMS FOR THE STANDARDIZATION OF NEAR-INFRARED SPECTROPHOTOMETERS. THIS EFFORT, COUPLED WITH RECENT ADVANCES IN MATHEMATICAL ALGORITHMS FOR REGRESSION MODEL TRANSFER, HAS CREATED AN OPPORTUNITY FOR THE DEVELOPMENT OF STANDARD CALIBRATION MODELS. THE PROPOSED RESEARCH FOCUSES ON TH ...

HIGH TEMPERATURE SUPERCONDUCTING (HTSC) FILMS HAVE A LARGE POTENTIAL AS DETECTORS OF ELECTROMAGNETIC RADIATION. TO BE USEFUL FOR TRANSFER STANDARD RADIOMETERS, IT IS NECESSARY THAT THE HTSC FILM QUALITY SHOULD BE VERY HIGH, BOTH FROM THE VIEW POINTS OF STRUCTURE AND SUPERCONDUCTING PROPERTIES. A MAJOR TASK, IN ORDER TO ACHIEVE HIGH SENSITIVITY, FAST RESPONSE, LOW NOISE LEVELS, AND UNIFORM SPECTRAL ...
