THE BIOCHEMICAL AND SYNTHETIC CAPACITY OF HIGHER PLANTS, AS SHOWN BY THEIR NATURAL CONTENT OF SUBSTANCES, HAS BEEN USED FOR CENTURIES IN SUPPLYING MATERIALS IMPORTANT IN PHARMACOLOGY AND IN FLAVORS AND FRAGRANCES. MANY OF THESE SECONDARY PRODUCTS ARE IN SHORT SUPPLY AND AN ENORMOUS EFFORT HAS TO BE EXTENDED TO GET THEM. ATTEMPTS TO USE CELL CULTURES OF HIGHER PLANTS AS A MEANS OF PRODUCING SECONDA ...

THE PURPOSE OF OUR RESEARCH PROGRAM IS TO DEVELOP A HELIUM-COOLED ABSOLUTE RADIOMETER SUITABLE FOR WIDE-BAND MEASUREMENTS OF THE EARTH'S RADIATION AT AN ANGULAR RESOLUTION TWO ORDERS OF MAGNITUDE BETTER THAN ACHIEVED WITHTHE EXISTING ERBE RADIOMETERS. WE HAVE CONSTRUCTED AND CHARACTERIZED A HELIUM-COOLED RADIOMETER OVER THE PAST FOUR YEARS. THIS SUCCESSFUL INSTRUMENT IS OPTIMIZED FOR LABORATORY ST ...

WE PROPOSE TO DEVELOP, FOR AIRCRAFT DEPLOYMENT, AN ACTIVE CANCELLATION TECHNIQUE THAT HAS SHOWN PROMISE IN PRELIMINARYLABORATORY TESTING. THE SYSTEM CONSISTS OF A PROVEN CANCELLATION ALGORITHM FOR REPETITIVE NOISE THAT USES A SYNCH PULSE FROM THE ENGINE, A HIGH POWER SOUND SOURCE MOUNTED NEAR THE PROPELLER THAT ADAPTS A SOURCE TECHNOLOGY DEVELOPED BY OUR STAFF, AND AN INNOVATIVE CONCEPT FOR DETECT ...

Robots will play an important role in NASA#39;s upcoming missions to the Moon and beyond.nbsp; They will need to manipulate their environment in complex and useful ways - carrying objects, using tools, and assisting crew.nbsp; NASArsquo;s humanoid robots have highly dexterous end-effectors, but developing software to fully utilize such hands remains a challenging task.nbsp; Grasping strategies are ...

SUPER ACCURATE ADAPTIVE COMPUTATIONAL SCHEMES FOR THE ANALYSIS OF FLUID STRUCTURE INTERACTION AND COMPLEX THREE-DIMENSIONAL INTERNAL FLOWS ARE TO BE DEVELOPED. NEW PETROV-GALERKIN FINITE ELEMENT METHODS FOR SOLVING THE NAVIER-STOKES EQUATIONS. COUPLED WITH THE EQUATIONS OF MOTION OF ELASTIC DUCTS AND MANIFOLDS, ARE TO BE DEVELOPED AND USED TO SIMULATE FLOWS IN AEROSPACE PROPULSION SYSTEMS (SUCH AS ...

NEW SPACECRAFT DESIGNS FEATURE LARGE STRUCTURES CHARACTERIZED BY LOW NATURAL FREQUENCIES, LIGHTLY DAMPED STRUCTURAL MODES, AND STRINGENT POINTING AND VIBRATION PERFORMANCE REQUIREMENTS. THESE LARGE SPACE STRUCTURES (LSS) POSE UNIQUE AND DIFFICULT CONTROL PROBLEMS. AN IMPORTANT PART OF THE SOLUTIONS TO THESE CONTROL PROBLEMS ISTHE DEVELOPMENT OF ACTUATORS THAT ALLOW THE APPLICATION OF FORCE AND OR ...

THE GOAL OF PHASE I IS DEVELOPMENT OF AN ADVANCED OPTICALLY PUMPED HELIUM MAGNETOMETER CONCEPT. THIS INSTRUMENT WILL MEASURE MAGNETIC FIELDS IN THE 1 TO 10-8 GAUSS RANGE WITH ORDER OF MAGNITUDE IMPROVEMENTS IN SENSITIVITY AND ABSOLUTE ACCURACY OVER EXISTING MAGNETOMETERS. OPTICALLY PUMPED HELIUM ISOTOPES CAN BE OPTICALLY PUMPED AND USED AS MAGNETOMETERS IN THE FOLLOWING THREE MODES: (1) VECTOR MOD ...

In this Phase I SBIR proposal, SandBox Semiconductor™ proposes to develop an Advanced Manufacturing and Material Measurements software tool called Weave ™ for accelerating and automating SEM image analysis for the semiconductor industry. During the development of a new manufacturing process line for a semiconductor device, tens of thousands of scanning electron microscopy (SEM) images are take ...

We propose to advance the state of the art in multi-pass optical cell technology by bringing several novel, previously unpublished, cell architectures to better maturity and to the attention of other researchers.nbsp; Optical multi-pass cells are devices that are fundamental to achieving high sensitivity in spectroscopic instruments for gas detection and measurement.nbsp; The proposed project is a ...

Advanced power is critical to NASA to meet future space exploration missions. NextGenrsquo;s innovative rechargeable battery solution goes far beyond lithium-ion for long duration energy storage to support lunar surface operations. NextGen, in collaboration with NEI Corporation, is proposing an advanced solid-state lithium-battery that takes advantage of the outstanding properties of two novel mat ...
