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 ...

A fast-paced continual increase on the ratio of CPU to memory speed feeds an exponentially growing limitation for extracting performance from HPC systems. Ongoing developments and trends make it clear that this ratio will keep increasing over the next decade. Breaking this memory wall is one of the most important challenges that the HPC community faces today. In this project we introduce novel and ...

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 ...

NASA's future human exploration missions will include remotely operated rovers performing surface exploration and science, as well as free-flyers to reduce the need for human Extra Vehicular Activity (EVA). As astronauts move deeper into space, it will be necessary for them to manage these robotic assets with less support from ground controllers. A flexible approach is needed to build and revise p ...

More than 1,500 Americans have lost a limb due to traumatic injury in combat in recent years.Upper limb loss can be treated with myoelectric prostheses, but such devices require intensive training to effectively operate. The need to concentrate and continuously react during training often takes amputees many months, with the result that many patients abandon use of the prosthesis. In the Phase I e ...

Selective laser melting, referred to as "Direct Metal Laser Sintering"(DMLS), "Metal Powder Bed Fusion" or "3D Printing" is an additive manufacturing process which allows extremely thin wall and complex structures. Off-axis aspherics are as easily produced as simple spherical optical surfaces. Nickel 11-13 % phosphorus alloy is the only hard, very fine grain, corrosion resistant material that can ...

Florida Turbine Technologies' (FTT) proposes an Additively Manufactured Modular Pump (AMMP) to provide a major leap forward in the Technology Readiness Level (TRL) of combined Additive Manufacturing (AM) technologies to dramatically reduce the cost, development lead time and subsequent deployment of a scalable, modular turbopump for rocket engine developers. This Phase I program will take the init ...

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 ...

This project addresses three modeling elements relevant to NASA's IADS research and ATD-2 project, two related to ramp operations at primary airports and one related to departure status at secondary airports. Departure scheduling requires departure status information from secondary airports that lack surface surveillance. We propose a method using aircraft transponder activation and data science ...

Thermal Stir Welding (TSW) advances the more conventional Friction Stir Welding (C-FSW) process by separating the primary process variables of metal stirring and forging from the control of the workpiece temperature. The independent heating is obtained by placing an induction coil in front of a specially modified tool to bring the workpiece to the appropriate joining temperature. However, studie ...
