Rice University graduate students and researchers have made nanowires between 6 and 16 nanometers wide. The wires are made from a variety of materials, including silicon, silicon dioxide, gold, chromium, tungsten, titanium, titanium dioxide, and aluminum. The development of sub-10-nanometer sizes shows...

The current steady-state performance-based system studies are not adequate to evaluate certain advanced technologies for the challenges associated with meeting the transient performance requirements without better definition and control of component operating margins. Additional...

When a maneuverable spacecraft confronts a potentially unsafe conjunction with another space object, its operators must decide whether to maneuver to mitigate the risk of a collision. Such decisions may not be straightforward, since the operators must balance their...

The class of 3DGRAPE codes is designed to generate volume grids using iterative methods to solve the non-linear, nonhomogeneous, elliptic partial differential heat equation with heat sources. The solution to the heat equation develops...

This software models the Delay Tolerant Link State Routing protocol. It runs inside the QualNet network simulator, and allows injecting of external bundles when running in emulation mode. It leverages QualNet’s library of networking protocols and JPL’s CCSDS models.

The EUROPA planning system is a general-purpose, reusable, artificial intelligence software system for automatically generating plans for performing complex activities in parallel, in accordance with constraints on activities and their interactions. One part of the system input...

A Massachusetts Institute of Technology team has developed a new, ultrasensitive magnetic-field detector. The device could lead to miniaturized, battery-powered devices for medical imaging.

Vendor software supplied with commercial acoustic emission equipment is incapable of performing the analysis required to characterize damage and make decisions on remaining life for NASA composite overwrapped pressure vessels (COPVs). The Acoustic Emission Analysis Applet (AEAA) software, currently...

The objective of this work was to develop a robust, cost-effective receiver with maximum dynamic range to track the frequency and power variation of a beacon signal. The result was the development of a frequency estimation algorithm that yields a more accurate...

A device developed by Massachusetts General Hospital investigators provides rapid, accurate molecular diagnosis of tumors and other diseases. The smartphone-based technology collects detailed microscopic images for digital analysis of the molecular composition of cells and tissues.

The software for NASA’s Northstar Systems computed tomography (CT) and Picometrix Terahertz CT systems do not have the ability to unwrap and reslice cylindrical CT data to allow top-to-bottom, 2D sheet views of the data. Therefore, it is difficult to size flaws laterally...

The NASA Technology Transfer System (NTTS) is a NASA-created technology transfer workflow management system, a schema-less database management system used to track the life-cycle of NASA inventions. It is built on XDB, a NASA homegrown XML database. Because of its schema-less approach to store data, NTTS can host a cluster...

While the late great comedian George Carlin had his infamous “Seven Words”, only six words are needed to kill innovation in any industry: “We’ve always done it this way.” How much more might be accomplished if those six words could be replaced with “what if”? What if we tried it this way? What if we...
