This project has two goals: (1) to develop and evaluate the feasibility of intelligent, computer-based self-management and household management applications that would improve the independent living capacity of persons with cognitive disabilities, and (2) to identify an agenda for full development of a deployable system in a Phase 2 project. Intelligent multimedia computer agents offer an untapped ...

This project researches, develops, and demonstrates the technical merit and feasibility of awearable device which (1) detects the direction of a sound source or motion, and (2) alerts the user viavibration, images, and captions to the direction of this sound source or movement relative to the currentposition of the individual. This provides the user with a sense of independence and personal safety ...

NASA aerocapture missions require an accurate evaluation of radiative thermal transport in order to simulate the aerothermal environment around space vehicles. However, present day computation of radiative transport in this complex multi-dimensional environment is frequently done using simple one-dimensional tangent-slab approximations or optically-thick approximations which compromise the accura ...

Remote chemical analysis via spectroscopy is an important tool in the arsenal or Earth and Planetary Science. Grating technology, which is the centerpiece of most modern spectroscopy systems, has not change significantly in the last 60 years since introduction of holographic gratings. Recently LightSmyth introduced new technology for design and fabrication of diffraction grating elements based on ...

The purity of hydrogen fuel is important in engine testing at SSC. The hydrogen may become contaminated with nitrogen, argon, or oxygen. The hydrogen from the fuel tanks or feed lines is analyzed beforehand. Therefore, there is a need for a non-intrusive, on-line, near real-time monitor for H2. The analytical technique should measure various impurities (molecular and atomic) simultaneously and be ...

Variable speed rotors will give helicopters several advantages: higher top speed, greater fuel efficiency, momentary emergency over-power, resonance detuning capability and a reduction in noise. The applicant proposes to develop such a system using a doubly-fed planetary gear box with advanced SiC-based power electronics and motors. The new components enabling variable speed will be rated at a f ...

We build a software tool which enables the user (airline or Air Traffic Service Provider (ATSP)) the ability to analyze the flight-level-by-flight-level permeability of airspaces constrained by weather-hazards (turbulence, icing, and convection). The Airspace Analyzer automatically determines the space-time boundaries where weather hazards constrain capacity. The solution approach is based on an ...

A novel urine pretreatment that will prevent biological growth or chemical instabilities in urine without using hazardous chemicals is proposed. Untreated urine fosters biological growth, ammonia generation, creation of bio-solids, and inorganic precipitates, which foul water and air reclamation hardware. The current Russian system employs hexavalent chromium, a strong oxidant and carcinogen, an ...

NASA captures and distributes operational knowledge in the form of procedures. These procedures are created and accessed by a range of people performing many different jobs. These people have different needs for procedure data and different ways of interacting with procedures. We propose an Procedure Integrated Development Environment which will present different editing modes and different views ...

We propose an alternative to using Microsoft Word for representing medical procedures that will make the procedures easier to construct and maintain, particularly when there are changes to the hardware or changes to the resulting format of the procedure. We call this alternative an "electronic procedure". Rather than a text-based document, this content-based document separates the text from the fo ...
