A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

TECHNICAL ABSTRACT: Bottom Feeder will be a highly maneuverable Autonomous Underwater Vehicle (AUV), with a tethered operations option and modular sensor bay, to support benthic optical surveys, coral reef mapping and health assessment, and be expandable for future survey operations. It will integrate a low drag hullform, a minimum of four degrees of independent motion control, a highly efficient ...

TECHNICAL ABSTRACT: Commercial marine aquaculture operators face many operational hazards including disease, predators, husbandry operations, and environmental changes. Most of theses risks are only identified with constant surveillance and physical presence at a farm site. However, human observation of risk factors is expensive, slow, and sometimes ineffective. Sensors are available to monitor in ...

TECHNICAL ABSTRACT: The mobile coastal monitor project is designed to prove out the research done in Phase I using a Proof of Concept demonstration craft. The Proof of Concept demonstrator will be a geometrically scaled version of the craft designed during Phase I. The Phase I craft, the Advanced Coastal Monitor (ACM) was designed to use state-of-the-art green power supplies and apply them as the ...

THERE IS A NEED FOR REFRIGERATION AS WELL AS HOT WATER HEATING ON MANNED SPACECRAFT. IN ORDER TO OBTAIN ENERGY ANDMASS EFFICIENT EQUIPMENT, IT IS PROPOSED TO USE COORDINATIVECOMPLEX COMPOUNDS, A SPECIAL CLASS OF NON-TOXIC SOLID-VAPOR MEDIA, FOR A DUAL DUTY THERMODYNAMIC CYCLE WHICH PROVIDES SIMULTANEOUSLY REFRIGERATION AND HOT WATER HEATING. SUCH CYCLES CAN BE DRIVEN WITH RELATIVELY LOW TEMPERATUR ...

ANALYTICAL METHODS AND COMPUTER SOFTWARE ARE TO BE DEVELOPED FOR CHARACTERIZING THE CHEMICAL KINETIC MECHANISMS THAT CONTROL LOX/HYDROCARBON COMBUSTION IN ROCKET ENGINES. CRITICAL AREAS OF TECHNOLOGY ARE TO BE IDENTIFIED. AN INNOVATIVE AND HIGHLY GENERAL METHOD WILL BEAPPLIED TO MODEL LOX/RP-1 COMBUSTION AS IT OCCURS IN GAS GENERATORS FOR PUMP FED ENGINES. THE METHOD WILL THEN BE EXTENDED TO MODEL ...
