The utility of this invention is to extract metals (semi-metals) or semiconductors from bulk nanotube samples. The bulk material is a mixture of the two. These materials can then be used to clone a particular type of nanotube, place a particular type in a device, generate smart materials,...

ZONE (Zeroing Out Negative Effects) is a method of biofeedback training for optimal athletic performance. ZONE is designed to improve athletes’ responses to stress, anxiety, and loss of concentration during competition. In the training environment, when the user successfully attains an optimal...

Two methods have been developed for functionalizing carbon nanotubes in solvent-free conditions. In one method, purified single-walled carbon nanotubes (SWNTs) and a diazonium salt are added to a metal vial, which is loaded with a stainless steel ball bearing. The metal...

Spaceflight and planetary exploration place severe constraints on the available bandwidth for downlinking large hyperspectral images. Communications with spacecraft often occur intermittently, so mission-relevant hyperspectral data must wait for analysis on the ground before it can inform...

A new chemistry was developed for existing hydrazine absorbent/detoxification pads. Enhancements include faster reaction rates, weight reduction, a color change that indicates spill occurrence, and another color change that indicates successful hydrazine degradation. The previous spill control pad, using...

The Orbiting Carbon Observatory (OCO) strives for trace gas observations with unprecedented accuracy and precision. This requires a retrieval algorithm with many major improvements over existing retrieval software in the representation of the transfer of solar radiation through the atmosphere and instrument,...

A modified electrospinning apparatus has been created for spinning highly aligned polymer fibers. Fiber placement, orientation, and porosity are difficult to control using conventional electrospinning apparatus. Conventional electrospinning creates randomly oriented fibers that are well suited to nonwoven...

The detection of distant objects in an image is relevant to applications in defense, security, and robotics. Successfully detecting objects of interest has been a common problem with respect to intelligent computer vision. Automatic target recognition (ATR) systems have been formulated and...

A software simulator was developed to simulate data flow from the Interface Data Processing Segment (IDPS) to the Science Data Segment (SDS) for the NPOESS Preparatory Project (NPP) via multiple Secure FTP (sftp) connections. The simulator is a multi-threaded Java program that handles the...

Orbital remote sensing provides a powerful way to efficiently survey targets for features of interest in inaccessible regions of the Earth as well as on other planets. One such feature of astrobiological relevance is the presence of surface sulfur deposits, which may...

Accurate assessment of circuits at cold temperatures is extremely difficult due to lack of models and tools that can simulate circuit behavior at cryogenic temperatures. A library of cryogenic temperature models was built, as well as a circuit simulator that can use those models and simulate...

An automatic Optimum Trade-Off Maximum Average Correlation Height (OT-MACH) filter generator for use in a gray-scale optical correlator (GOC) has been developed for improved target detection. While the OT-MACH filter has been shown to be an optimal filter for target detection,...

Machine learning techniques have shown considerable promise for automating common visual inspection tasks. For example, Support Vector Machine (SVM) classifiers that have been learned from labeled training data deliver strong detection performance both for finding human faces in...

A number of deep space missions have imaged plumes at Io, Enceladus, and other smaller bodies. These phenomena provide valuable information regarding these bodies. To date, this imagery has been captured fortuitously. The ability to utilize onboard processing to conduct campaigns capturing large numbers...

The James Webb Space Telescope (JWST) Integrated Simulation and Test (JIST) environment is a software-only system simulator that provides an environment to exercise JWST flight software subsystems and interfaces. JIST is capable of executing the unmodified flight software binaries in an operational...
