The same Duke University Pratt School of Engineering research team that first developed real-time, 3D ultrasound imaging has modified the commercial version of the scanner to produce an even more realistic perception of depth. The researchers created an updated version of the image-viewing software, making it possible to achieve a...

By 2020, NASA plans to establish a long-term human presence on the Moon, which means that necessities such as fuel, food and oxygen, and spare parts would have to get from the Earth to the Moon as predictably as an Earth-based delivery system - especially when the delivery point is 240,000 miles...

World Wind allows users to zoom from satellite altitude down to any place on Earth, leveraging high-resolution LandSat imagery and SRTM (Shuttle Radar Topography Mission) elevation data to experience Earth in visually rich 3D. In addition to Earth, World Wind can also visualize other planets, and there are already...

JavaGenes is a general-purpose, evolutionary software system written in Java. It implements several versions of a genetic algorithm, simulated annealing, stochastic hill climbing, and other search techniques. This software has been used to evolve molecules, atomic force field parameters, digital circuits, Earth...

By 2020, NASA plans to establish a long-term human presence on the Moon. To make this possible, a reliable stream of consumables such as fuel, food and oxygen, spare parts, and exploration equipment would have to make its way from the Earth to the Moon as predictably as any Earth-based delivery system. To figure out how to do...

Methods are available for the determination of building stability in the event of an earthquake. These methods involve the development of existing shaking table technology to allow more efficient characterization of structural properties. View this technology here. An approach accompanied by a comprehensive algorithm and...

A researcher at Technische Universiteit Eindhoven (Eindhoven, the Netherlands) has developed a software patch that can increase a car's fuel efficiency to a total fuel savings of 2.6%, without having to replace any of the parts of the car. Uploading a software patch to the car's computer and adding one small cable suffices.

IM Mobile -- World's fastest, full-functionality, single-user Data Base Management System (DBMS), with unique built-in synchronization. It is about four times faster than Microsoft SQL Server 2005 Mobile on a PDA, making the user experience completely different. Click here.

The AIRSAR automated, Web-based data processing and distribution system is an integrated, end-to-end synthetic aperture radar (SAR) processing system. Designed to function under limited resources and rigorous demands, AIRSAR eliminates operational errors and provides for paperless archiving. Also, it provides a...

A software interface has been devised to facilitate optimization of the shapes of valves, elbows, fittings, and other components used to handle fluids under extreme conditions. This software interface translates data files generated by PLOT3D (a NASA grid-based plotting-and- data-display program)...

A software library has been developed that takes a highlevel description of a pattern to be satisfied and applies it to a target. If the two match, it returns success; otherwise, it indicates a failure. The target is semantically a tree that is constructed from elements of terminal and non-terminal...

This software addresses the problem of how to efficiently execute a knowledge base in the presence of missing data. Computationally, this is an exponentially expensive operation that without heuristics generates a search space of 1 + 2n possible scenarios, where n is the number of rules...

A computer program translates Unified Modeling Language (UML) representations of state charts into source code in the C, C++, and Python computing languages. ("State charts" signifies graphical descriptions of states and state transitions of a spacecraft or other complex system.) The UML representations constituting the input...

The Pointing History Engine (PHE) is a computer program that provides mathematical transformations needed to reconstruct, from downlinked telemetry data, the attitude of the Spitzer Space Telescope (formerly known as the Space Infrared Telescope Facility) as a function of time. The PHE also...

Software has been developed for an improved method of correcting for the atmospheric optical effects (primarily, effects of aerosols and water vapor) in spectral images of the surface of the Earth acquired by airborne and spaceborne remote-sensing instruments. In this method, the variables...

Small, universal mobile receivers are needed that are capable of receiving mobile satellite television signals. These receivers should be similar to those installed and used by satellite radio. The receivers will convert the signal from a satellite to a mounted or OEM satellite, thus delivering cable television to mobile...

PyCraft is a computer program that provides an interactive, workbench-like computing environment for developing and testing algorithms for multibody dynamics. Examples of multibody dynamic systems amenable to analysis with the help of PyCraft include land vehicles, spacecraft, robots, and molecular...

A Mathcad computer program largely automates the design and analysis of the restraint layer (the primary load-bearing layer) of an inflatable vessel that consists of one or more sections having cylindrical, toroidal, and/or spherical shape(s). A restraint layer typically comprises webbing...

A computer program that belongs to the class known among software experts as output truth-maintenance systems (output TMSs) has been devised as one of a number of software tools for reducing the size of the knowledge base that must be searched during execution of artificial-intelligence...

Marshall Aerospace Vehicle Representation in C (MAVERIC) is a computer program for generic, low-to-high-fidelity simulation of the flight(s) of one or more launch vehicle(s) or spacecraft. MAVERIC is designed to accommodate multi-staged vehicles, powered serially or in parallel, with...

A computer program has been devised for controlling a machine that is an integral combination of magnetic bearings and a switched-reluctance motor. The motor contains an eightpole stator and a hybrid rotor, which has both (1) a circular lamination stack for levitation and (2) a six-pole...

Machine Aided Indexing (MAI) is a Web-based application program for aiding the indexing of literature in the NASA Scientific and Technical Information (STI) Database. MAI was designed to be a convenient, fully interactive tool for determining the subject matter of documents and identifying keywords. The...

The ARINC 739 Switch is a computer program that arbitrates control of two multi-function control and display units (MCDUs) between (1) a commercial flight-management computer (FMC) and (2) NASA software used in research on transport aircraft. (MCDUs are the primary interfaces between pilots and FMCs...
