IMPROVEMENTS IN A FIBER OPTICALLY COUPLED CCD CAMERA ARE PROPOSED WHICH WOULD REDUCE EXPOSURE TIMES, EXTEND DYNAMIC RANGE, IMPROVE RESOLUTION, AND FACILITATE AUTOMATION OF X-RAY DIFFRACTION OF PROTEIN CRYSTALS. IN PHASE I, THE SYNCHROTRON X-RAY DIFFRACTION PATTERN OF A KNOWN PROTEIN CRYSTAL WILL BE IMAGED AND CORRECTIONS TO THE OPTICAL DISTORTIONS IN THE FIBER OPTIC BUNDLE WILL BE MADE TO TEST THE ...

HIGH SPEED OPTICAL LINKS ARE FINDING EVER INCREASING USES INOPTICAL COMMUNICATIONS AND SIGNAL PROCESSING APPLICATIONS. CURRENTLY AVAILABLE PLANAR WAVEGUIDE LASERS USED IN THESE LINKS SUFFER FROM A HIGH INSERTION LOSS DUE TO A MODE MISMATCH BETWEEN THE FIBER AND THE MODULATOR AND THE INABILITY TO IMPLEMENT A 2D ARRAY CONFIGURATIONS. THE VERTICAL CAVITY SURFACE EMITTING LASERS (VCSEL) CURRENTLY UNDE ...

THE PROPOSED PROGRAM IS AIMED AT DEVELOPING ALX GA1-XN/GAN HETEROSTRUCTURE DEVICES FOR HIGH TEMPERATURE SENSOR AND ELECTRONICS APPLICATIONS. WE WILL FOCUSS ON AN ALXGA1-XN BASED HIGH ELECTRON MOBILITY TRANSISTOR (OR HEMT) FOR USE ASA HIGH TEMPERATURE MICROWAVE DEVICE OR AS A SENSITIVE ULTRAVIOLET DETECTOR. GAN HAS A LARGE BANDGAP OF 3.2 EV WHICH GIVES IT A GREATER BREAKDOWN VOLTAGE AND A HIGHER SA ...

THE SELECTION OF A POLYMER FOR USE IN A BIOMEDICAL APPLICATION IS BASED UPON THE PHYSICAL CHARACTERISTICS OF THE POLYMER SUCH AS STRENGTH AND FLEXIBILITY AND UPON THE BIOCOMPATIBILITY OF THE MATERIAL WITH TISSUE. IT IS FREQUENTLY THE CASE THAT COMPROMISES MUST BE MADE BETWEEN THESE TWO POTENTIALLY CONFLICTING REQUIREMENTS. THE IDEAL SOLUTION TO THIS PROBLEM IS TO ENABLE THE SELECTION OF THE POLYME ...
