MOST LASER SCANNING SYSTEMS ARE MECHANICAL, UTILIZING A MOTOR TO ROTATE A PRISM, MIRROR, OR HOLOGRAPHIC GRATING. SUCH MECHANICAL SYSTEMS ARE OR RELATIVELY LARGE SIZE AND MASS. THERE IS A NEED FOR A SOLID STATE SCANNING DEVICE WHICH WOULD OFFER BENEFITS OF REDUCED SIZE AND MASS, NO MOVING PARTS, IMPROVED RELIABILITY, LOW COSTS, AND LOW POWERREQUIREMENT. WE PROPOSE TO DEVELOP AN INTEGRATED OPTICS (I ...

RECENT TECHNICAL ADVANCEMENTS IN THE SEMICONDUCTOR DEVICE AND POWER CONDITIONING TECHNOLOGIES HAVE LED TO SUBSTANTIAL IMPROVEMENTS IN TERMS OF SIZE, WEIGHT, EFFICIENCY AND POWER QUALITY OF THE POWER CONDITIONING EQUIPMENT WHICH IS BEING CONSIDERED FOR SPACE APPLICATIONS. WITH THESE ADVANCEMENTS COMES AN ABUNDANCE OF DESIGN CHOICES AND INCREASED DEGREES OF FREEDOM WITH RESPECT TO POWER SYSTEM CONTR ...

ONE PROMISING APPROACH TO THE DEVELOPMENT OF GENERALIZED MODELS OF COMMUNICATION SYSTEMS IS COMPOSITION OF MODELS FROM COMPONENT MODEL MODULES. IN THIS APPROACH, MODELS OF INDIVIDUAL SYSTEM COMPONENTS ARE DEVELOPED AND SUBSEQUENTLY LINKED INTO A MODEL BY MODEL COMPOSITION SOFTWARE. AN INTEGRATED SOFTWARE ENVIRONMENT SUPPORTS THIS TECHNOLOGY BY MANAGING A MODELBASE OF MODEL MODULES PROVIDING FOR TH ...

A CONSIDERABLE AMOUNT OF R & D WORK HAS BEEN DONE FOR THE WANKEL ROTARY ENGINE APPLICATION TO AUTOMOBILES, PLANES, ETC. RESULTING IN SIGNIFICANT PROGRESS. THE PERFORMANCE, RELIABILITY AND DURABILITY THAT THE WANKEL HAS DEMONSTRATED, HOWEVER, FALLS SHORT OF THE POPULAR DIESEL ENGINE. THE ADIABATIC, TURBOCOMPOUND CONCEPT THAT HAS BEEN DEMONSTRATED FOR THE DIESEL IS THOUGHT TO BE MORE BENEFICIAL TO T ...

THE PROGNOSTIC THREE DIMENSIONAL MESOSCALE (P3DM) MODEL, ORIGINALLY DEVELOPED BY NOAA AS A FLORIDA SEA BREEZE MODEL, HAS UNDERGONE OVER A DECADE OF CONTINUOUS DEVELOPMENT. INITIAL STUDIES SUGGESTED THAT THERE WAS A STRONG CORRELATION BETWEEN REGIONS OF PREDICTED MESOSCALE SURFACE CONVERGENCE AND THE INITIAL FORMATION OF SEA BREEZE TRIGGERED THUNDERSTORMS UNDER SYNOPTICALLY UNDISTURBED CONDITIONS. ...

CURRENT LIFE-SUPPORT SYSTEMS FOR EXPERIMENTAL ANIMALS CANNOT BE USED FOR DEVELOPMENTAL STUDIES OF ANIMALS IN SPACE. AN INNOVATIVE APPROACH TO THE DESIGN OF AN ANIMAL DEVELOPMENT HABITAT, COMPATIBLE WITH THE MIDDECK LOCKERS OF THE SPACE SHUTTLE, IS BASED ON STUDIES OF NATURALLY-OCCURRING MATERNAL BURROWS OF RODENTS, SURFACE/VOLUME RATIOS OF DIFFERENT HABITAT CONFIGURATIONS, AND ANALYSIS OF PHYSIOLO ...
