HIGH DENSITY INTEGRATION OF EXTERNAL OPTICAL WAVEGUIDE MODULATORS THAT MAY BE USED EFFECTIVELY AT BANDWIDTHS IN EXCESS OF 30 GHZ IS TO BE INVESTIGATED. THIS REQUIRES LAUNCHING MICROWAVE MODULATION ENERGY TO THE MODULATION TRANSMISSION LINE WITH MINIMUM RADIATED ENERGY, INTERCONNECTING THE TRANSMISSION LINE TO COAXIAL CABLE IN MINIMAL SPACE, INCREASED ISOLATION BETWEEN SIGNAL LINES OF MULTIPLE MODU ...

1The Navy has been investigating membrane distillation (MD) as a means of desalinating seawater aboard ships since 1983. MD could potentially offer advantages over conventional distillation, the technology in most common use now, and could offer an alternative to other promising membrane technologies such as reverse osmosis. These potential advantages include small size, simplicity, and low energy ...

THE DETECTION OF DRUG RESISTANT FORMS OF PLASMODIUM FALCIPARUM HAS TRADITIONALLY REQUIRED A 24-48 HR CULTURE PERIOD WITH ANALYSIS CONDUCTED BY MICROSCOPICALLY MEASURING THE LEVEL OF PARASITEMIA FOR EACH TEST POINT. IT IS OUR INTENT TO MODIFY THIS PROCEDURE TO ALLOW EARLIER DETECTION OF THE DRUG RESISTANT FORM OF THE PARASITE AND TO PERMIT THIS DETECTION TO BE MADE WITH SIGNIFICANT REDUCTION IN MAN ...

THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) HAS IDENTIFIED A NEED FOR NEW INSTRUMENTATION TECHNIQUES CAPABLE OF VELOCITY MEASUREMENTS FOR HIGHLY UNSTEADY, COMPLEX VORTICAL FIELDS CHARACTERISTIC OF FLOW AROUND A SUBMARINE. THIS PROPOSAL, PREPARED IN COLLABORATION WITH THE PRINCETON UNIVERSITY LASER AND APPLIED PHYSICS GROUP, OFFERS A NEW OPTICAL FLOW FIELD DIAGNOSTIC CAPABLE OF THREE-DIME ...

ADVANCED EXPERIMENTAL METHODS THAT CAN PROVIDE QUANTITATIVE FLOW FIELD IMAGING DATA IN HYPERSONIC FLOWS ARE REQUIRED FOR THE DEVELOPMENT OF ADVANCED HYPERSONIC TECHNOLOGY AND THE VALIDATION OF COMPUTATIONAL FLUID DYNAMIC CODES. TO SATISFY THESE REQUIREMENTS, AN EVALUATION OF POTENTIAL IMPROVEMENTS IN THE ELECTRON-BEAM FLUORESCENCE TECHNIQUE USED FOR PLANAR FLOW VISUALIZATION IN THE 20-INCH HYPERSO ...
