THIS PROJECT DEVELOPS INTERFACE SOFTWARE THAT ALLOWS SCIENTIFIC AND ENGINEERING APPLICATIONS TO ACESS HETEROGENEOUS COLLECTIONS OF COORDINATED-REFERENCED DATA INDEPENDENT FASHION. COORDINATE-REFERENCED DATA ARE MEASUREMENTS PERFORMED ON POINTS IN SPACE, TIME AND WAVELENGTH IN APPLICATIONS SUCH AS REMOTE SENSING, SURVEILLANCE, AND ASTRONOMY. ATTEMPTS AT STANDARDIZING THESE DATA USALLY FAIL BECAUSE ...

IT IS WIDELY RECOGNIZED THAT BEHAVIORAL MEASURES OF WORKLOADARE INADEQUATE. EVENT-RELATED POTENTIALS (ERPS) RECORDED FROM THE HUMAN SCALP ARE A PROMISING ALTERNATIVE IN THAT THEY HAVE BEEN SHOWN TO REFLECT SELECTIVE ATTENTION, EXPECTANCIES, AND DECISION-MAKING PROCESSES. MOST PREVIOUS ERP STUDIES OF WORKLOAD HAVE BURDENED THE SUBJECT WITH A CONTRIVED SECONDARY TASK. THE PRESENT STUDY, BY TAKING AC ...

ECHELLE SPECTROGRAPHS DESIGNED FOR THE VACUUM ULTRAVIOLET HAVE BEEN LIMITED IN THEIR USEFULNESS DUE TO LOW EFFICIENCY AND STRAYLIGHT OF THE ECHELLE GRATING. THIS PROJECT APPLIESNEW APPROACHES IN COATING TECHNOLOGY AS A MEANS TO PROVIDE IMPROVED DEVICES. THE R&D EFFORT INCLUDES THE STUDY OF VACUUM DEPOSITION CONDITIONS AND THEIR RELATIONSHIP TO THE RULEABILITY OF ECHELLE GROOVES. SEVERAL TEST COATI ...

NEW TECHNIQUES ARE NEEDED IN THE FABRICATION OF HIGH-QUALITYDIFFRACTION GRATINGS OF THE TYPE REQUIRED FOR PLANNED AND ANTICIPATED SPACE ASTRONOMY INSTRUMENTS. GRATINGS WITH THE REQUIRED LOW LEVELS OF SPECTRALLY-SCATTERED LIGHT AND LARGE BLAZE ANGLES ARE NOT CURRENTLY AVAILABLE, AND IT IS DOUBTFULTHAT SUCH GRATINGS CAN BE PRODUCED BY THE TRADITIONAL METHODOF MECHANICAL RULING. A MORE PROMISING APPR ...

POLAR GRAPHIC DISPLAYS PRESENT QUANTITATIVE INFORMATION ABOUT A SYSTEM'S PARAMETERS AT THE NODES OF A GEOMETRIC FIGURE. BY TAKING ADVANTAGE OF HUMAN PATTERN RECOGNITION CAPABILITIES, THIS DISPLAY CONCEPT MAY ENHANCE OPERATOR'S ABILITY TO RAPIDLY ASSESS SYSTEM STATUS. THE PRESENT RESEARCH ADDRESSES BASIC AND APPLIED ISSUES IN HUMAN VISUAL PROCESSING AND DECISION-MAKING WITH POLAR GRAPHICS, IN AN EF ...

THE OBJECTIVE OF THIS RESEARCH IS TO STUDY THE FEASIBILITY OF APPLYING ARTIFICIAL INTELLIGENCE TECHNOLOGY TO THE DERIVATION OF SPACECRAFT DATA SYSTEM REQUIREMENTS FROM USER SCENARIOS. DURING PHASE I THE RESEARCH WILL BE DIRECTED TOWARD THE DEVELOPMENT OF A FORMAL NOTATION FOR THE EXPRESSION OF SCENARIOS WHICH ALLOWS THE USER THE NECESSARY FLEXIBILITY IN DESCRIBING HIS USE OF THE SYSTEM. THIS NOTAT ...
