Aniuk Consulting, LLC, proposes to create a GIS software toolkit for monitoring areal snow cover extent and producing streamflow forecasts. This toolkit will be packaged as multiple extensions for ArcGIS 9.2 and provides users with a means for easily ingesting NASA EOS satellite images (for snow cover analysis), preparing hydrologic model inputs, and visualizing streamflow forecasts. Primary pro ...

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 ...

The project develops a conversational personal information manager named JotChat whichallows users to communicate with computers using ordinary language, leveraging a natural languagetechnology called Tridbit technology. Tridbit technology simplifies aspects of the natural languageunderstanding problem through its unique knowledge representation model. JotChat users enter andretrieve information i ...

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 ...

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 ...

The severity of the lunar dust problems encountered during the Apollo missions were consistently underestimated by ground tests, illustrating the need to develop significantly better lunar dust simulants and simulation facilities. ORBITEC proposes to develop a family of High-Fidelity Lunar Dust Simulants that will better match the unique properties of lunar dust than existing simulants (such as JS ...

The concept development and test of a water-based, advanced Phase Change Material (PCM) heat sink is proposed. Utilizing a novel material choice for both an expansion diaphragm and the PCM case itself, the PCM can accommodate both the expansion of the freezing water-based material and very low temperature of approximately -250F. The water-based PCM itself would be non-toxic and non-flammable, bu ...

Metabolic heat regenerated Temperature Swing Adsorption (MTSA) technology is proposed for a Portable Life Support System to remove and reject heat and carbon dioxide (CO2) regardless of the environment (lunar or Mars, vacuum or CO2), as well as to help control humidity in the ventilation loop. The basic principal is removal of metabolically-produced CO2 by an adsorbent with regeneration using a t ...

The proposed effort will combine a low cost physical modeling approach with inductive, data-centered modeling in an aerosopace relevant context to demonstrate effective, low cost data mining. In particular Phase I will evaluate various hybrid architecture concepts on the basis of false positive and fasle negative rates. The approach will use domain decompostiition to partition the physical pla ...

We shall develop wide temperature range DC-DC boost converters that can be fabricated using commercial CMOS foundries. The boost converters will increase the low voltage supply (~ 0.7 to 3V) of an advanced CMOS integrated circuit to the higher values (3-10V) required for integrated command/control/drive electronics for sensors, actuators and instrumentation. The high voltage capability is a result ...
