This research refines existing associate decision aiding technology and applies it to a new, larger air traffic management (ATM) domain. We have shown in other NASA projects how our associate systems can provide Distributed Air-Ground (DAG) decision aiding to pilots, air traffic controllers, and airline dispatchers within the ATM system of a UAV free NAS. Our existing C2IT software provides decisi ...

MOST TYPICAL PROBLEMS IN STRUCTURAL ENGINEERING ARE BEST ANALYZED BY APPROXIMATING AN OBJECT'S GEOMETRY WITH FINITE ELEMENTS. SELECTING AN APPROPRIATE MESHING STRATEGY FOR A GIVEN SOLID REQUIRES KNOWLEDGE ABOUT FINITE ELEMENT THEORY IN GENERAL, AND ABOUT PACKAGE-SPECIFIC DETAILS IN PARTICULAR. THE ADEPT SYSTEM INTEGRATES A TRADITIONAL SOLIDMODELER WITH AN EXPERT SYSTEM EQUIPPED WITH THIS KNOWLEDGE ...

This proposal will present an innovative Phase I research and design plan for a reliable LOX pumping system for use in NASA vehicle loading. Due to seal problems with the current LOX loading pumps, the main focus of the Phase I effort will involve design and development of an innovative sealing solution that does not use a failure prone mechanical seal. The seal solution proposed is a combination ...

THE OBJECTIVE OF THIS PROJECT IS TO DESIGN AND FABRICATE AN INNOVATIVE FINGERTIP-SHAPED TACTILE TELEPRESENCE SYSTEM FOR DEXTEROUS TELEROBOTIC SYSTEMS. THE PRINCIPAL TASKS TO BE PERFORMED ARE: (1) DESIGN OF VARIOUS MINIATURE TACTILE STIMULATOR ELEMENTS AND EVALUATION OF THE ACTUATION STRENGTH, DISPLACEMENT MAGNITUDE, FREQUENCY RESPONSE RANGE, AND THERMAL LOADING CHARACTERISTICS, (2) CONSTRUCTION OF ...

The Bioastronautical Systems Development Company (BSDC) proposes to develop habitat technologies for conducting long-term commercial research with mice in microgravity. Our research addresses solicitation section B4.02 Space Commercialization for the design/development of microgravity payloads for space station applications that lead to commercial products or services. In partnership with BioServe ...

NASA IS CURRENTLY SUPPORTING A VERY PROMISING PROJECT FOR DEVELOPMENT OF A HIGH-POWERED MULTIPROCESSOR SYSTEM, THE NAVIER-STOKES COMPUTER (NSC). WHILE MULTILEVEL ALGORITHMS ARE BEING STUDIED IN THE NSC ENVIRONMENT FOR SOLVING THE ELLIPTIC EQUATIONS THAT ARISE IN DISCRETIZING INCOMPRESSIBLENAVIER-STOKES EQUATIONS, NO RESEARCH HAS YET FOCUSED ON LOCAL ADAPTIVE SCHEMES FOR THIS PURPOSE. THIS IS IMPOR ...

THE USE OF IMAGERY FOR THE PRESENTATION OF DATA IS BECOMING INCREASINGLY COMMON. INTEGRATING IMAGE DATA WITH GRAPHIC DATA STRUCTURES AND FEATURE INFORMATION IS VERY DIFFICULT USING TRADITIONAL DIGITAL REPRESENTATIONS. SEPARATE IMAGE AND FEATURE INFORMATION DATABASES ARE COMMONLY USED, BUT THE ANALYST IS REQUIRED TO MAINTAIN TWO OR MORE DATABASES AND TO PERFORM INTEGRATION OF THE INFORMATION IN HIS ...

The MIL-STD-1553B Bus is a widely supported data bus for avionics applications and compatible with most of the avionics equipment. However, its low data rate (1 Mbps) and command-response architecture are not suitable for many modern applications such as on-board autonomy. Therefore, the avionics industry recently has been interested in adopting the IEEE 1394A Bus as the next generation avionics b ...

Enormous data capacities and high read/write rates make optical holographic data stor-age (HDS) systems the most promising approach for next-generation computer mass-storage solutions. Recent breakthroughs in holographic recording media have dramatically accelerated the development of commercial HDS products, and have shifted the development focus to opti-mization of HDS optical systems and compon ...
