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 ...

Although the performance of naval systems for Anti-Submarine Warfare and Counter-Torpedo Detection, Classification, and Localization systems are presently adequate for current missions they are limited by the size, power and detection range of the associated sonar transducer arrays. What is required for the emerging missions are approaches that will reduce the volume and weight of present arrays w ...

Impact Technologies, in collaboration with Tennessee State University, propose to develop and demonstrate an adaptive system identification and multi-loop control methodology that provides real-time aircraft structural mode suppression associated with aeroservoelastic interaction under upset and damage conditions. The proposed program will develop an effective real-time aircraft structural model, ...

Producing return fuel on Mars rather than carrying it from Earth significantly reduces the mass that must be lifted from Earth for a manned mission to Mars. The most practical propulsion combination that can be produced is methane and oxygen. Using propellant components made on Mars to generate electric power on the return voyage further reduces the mass that must be lifted.We are proposing to d ...

In recent years, the military has been integrating robotic systems into tasks previously performed entirely manually by soldiers. Examples include explosive ordnance disposal (EOD), surveillance and reconnaissance, urban search and rescue (USAR), chemical, biological, and nuclear (CBN) operations, and medical assistance and evacuation. A typical application is for a soldier (remote operator) to te ...

THE TECHNICAL OBJECTIVE OF THIS PROJECT IS TO ESTABLISH THE FEASILBILITY OF SATISFYING THE REQUIREMENTS OF THE U.S. ARMY COMMUNICATIONS ELECTRONICS COMMAND (CECOM) FOR RAPID AND EFFECTIVE MODELING OF U.S. ARMY COMMUNICATION SYSTEMS. THE METHOD WE PROPOSE FOR SATISFYING THESE REQUIREMENTS IS TO ADAPT A TOP-DOWN DESIGN SYSTEM FOR ELECTRONIC SYSTEMS BEING DEVELOPED FOR THE U.S. NAVY TO MODEL-ING OF C ...

The proposed research will explore innovative flight control methodologies combining recent advances in system identification, novel flight sensors, and neural network based adaptive flight control design to develop a new, high bandwidth flight controller architecture capable of rejecting the disturbing effects of wind gusts and turbulence. The proposed controller architecture will be most appropr ...

THE MOST CRITICAL ASPECT OF THE RADIO FREQUENCY POWER SUPPLY FOR THE NEUTRAL PARTICLE BEAM INTEGRATED EXPERIMENT IS ITS POWER TO WEIGHT RATIO. IN ADDITION, THE SPACE-QUALIFIED 45V POWER SUPPLY MUST BE ABLE TO SUPPLY 27,000 AMP PULSES DOWN TO 350 MICROSECONDS WITH ONLY A 2 - 3% VOLTAGE DROP. PROTON EXCHANGE MEMBRANE FUEL CELLS HAVE POTENTIALLY THE HIGHEST POWER TO WEIGHT RATIO OF ANY TYPE OF FUEL C ...

Navy ships use of gas turbine engines for both main propulsion and electrical power generation. With typical simple cycle thermal efficiencies of around 32-35%, a great deal of energy is lost as exhaust waste heat from the gas turbines. Clearly there is a need to develop systems that can recover as much as possible of this waste energy, and as stated in the program goal, achieve at least a 20% red ...

The availability of high-quality potable water is essential in crewed space missions. Closed loop water recycling systems as well as potable water holding tanks and waterlines provide environments for biofilm formation that can facilitate the growth of human pathogens, as well as organisms that can cause deterioration of distribution lines. Prevention requires the maintenance of a chemically stabl ...
