DESCRIPTION (provided by applicant): The long-term goal of the proposed research is to develop a novel quantitative particle agglutination technology for improving the performance of detection of human immunodeficiency virus (HIV) antibody in body fluids. The conventional particle agglutination assays have serious drawbacks such as limited sensitivity, long time of incubation, subjectivity and la ...

This project builds upon on previous work on a theory-based tool that assesses and trains children with autism spectrum disorders social information processing (SIP) skills. This system, the virtual environment for social information processing (VESIP), is a significant improvement over existing measures of social skill in several ways: (1) its standardized, computer-delivered form reduces trainin ...

CERTAIN CONJUGATED ORGANIC POLYMERS POSSESS INTERESTING NONLINEAR OPTICAL PROPERTIES. TO DATE THERE EXIST SEVERAL OF THESE POLYMERS BUT ALTHOUGH THEY MAY HAVE LARGE THIRD ORDER NONLINEAR SUSCEPTIBILITIES, X(3), THEY MAY LACK THE NECESSARY OPTICAL QUALITY (LINEAR OPTICAL PROPERTIES), MECHANICAL PROPERTIES, OR LASER DAMAGE THRESHOLD TO BE OF PRACTICAL INTEREST. THE PROPOSED EFFORT WILL DETERMINE THE ...

TEAMWORKS IS AN APPROACH TO THE MULTIPLICATION OF COMBAT POWER THROUGH THE EVOLUTIONARY DEVELOPMENT OF TELEROBOTIC SYSTEMS. WE PROPOSE TO BUILD A SIMULATION GAMING LABORATORY, DISTRIBUTED OVER A NETWORK OF PERSONAL COMPUTERS, FOR THE STUDY OF TEAMWORK AMONG HUMANS AND ROBOTS. OUR LONG-TERM OBJECTIVE IS TO DEVISE AN ADVANCED AUTIO/ VISUAL INTERFACE THROUGH WHICH A TANK COMMANDER CAN MANEUVER A SIMU ...

1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data nonlinearity will be corrected by a calibration process acting upon the x-ray data. The blurring er ...

Children with significant hearing loss continually exhibit low reading levels, due in part to the difficulty they face upon entering school of understanding basal reading vocabulary, especially critical service words. Service words cannot easily be learned through the use of pictures or objects but constitute up to 75% of all words used in basal readers, including prepositions, conjunctions, artic ...

A MAGNETIC GRADIOMETER BASED ON THE PROVEN CONCEPT OF A FIBER OPTIC INTERFEROMETRIC MAGNETIC TRANSDUCER IS PROPOSED FOR THE DETECTION OF DEEPLY BURIED ORDNANCE. THE LOCAL MAGNETIC GRADIENT CAN BE MEASURED WITH HIGH SENSITIVITY WITH A MACH-ZEHNDER OPTICL INTERFEROMETER; THE TWO SENSING ARMS ARE COMPOSED OF A SINGLE MODE OPTICAL FIBER COATED WITH, OR OTHERWISE ATTACHED TO, A MAGNETOSTRICTIVE MATERIA ...

This Small Business Innovation Research Phase II project aims to develop a commercial optically-resonant nanotweezer chip and corresponding instrumentation. The nanotweezer technology, originally developed at Cornell University, uses localized optical forces to directly manipulate biological (nucleic acids & proteins) and non-biological (nanoparticles) materials as small as a few nanometers in siz ...

THIS PROPOSAL SHOWS A METHOD FOR SIGNIFICANTLY ENHANCING THE SPEED AND EFFICIENCY OF THE OPTICAL DISK HEAD. (1) WEIGHT COULD BE REDUCED WITH THE PROPOSED DESIGN FOR HOLOGRAPHIC OPTIC ELEMENTS (H.O.E.), WHICH HAVE FEWER ELEMENTS AND COULD BE MADE WITH LIGHTER AND LESS EXPENSIVE PLASTIC MATERIALS. (2) THE PROPOSED H.O.E. CONFIGURATION ALLOWS REDUCTION OF THE F-NUMBER WITHOUT IMAGE QUALITY DEGRADATIO ...
