Traditional methods for change detection involve the pixel-wise registration of two images and a subsequent differencing operation that highlights any changes at the individual pixel level. These methods have two limitations: (1) they are computationally expensive, and (2) they are...

Oxidation chemical reactions of many practical fuels encompass thousands of species. When simulating complex turbulent reactive flows, it is impossible to account for the time and spatial evolution of all these species given current and foreseeable-future computer memory and time. This innovation...

Porous silicon nanowires are fabricated by two-step, metal-assisted electroless chemical etching of p-type or n-type silicon wafers. This method, in combination with nanolithography or nanopatterning, can be applied to fabricate porous silicon nanostructures of different...

The Integrated Modular Avionics (IMA) architecture being developed for space applications requires that sensor data be autonomously sampled and transmitted to the system network. This transmission needs to occur on a predetermined, fixed...

A 4-channel digitizer was designed, built, and tested. The very large, complex board enables SweepSAR. The proposed Deformation, Eco-Systems, and Dynamics of Ice Radar (DESDynl-R) Lband SAR instrument employs multiple digital channels to optimize resolution...

NASA has an interest in utilizing the Ka-band frequency allocation. One of the main reasons for migrating to Kaband is the need for higher frequency bandwidth to enable higher data rates. A dual circular polarized wideband antenna for Ka-band communications applications was...

This software addresses the problem of an autonomous vehicle patrolling a region for objects of interest using multiple cameras. The system must identify and track the objects over time and localize their positions in the world. It implements an autonomous perception and...

Electric conduction in polymers is one of the key elements in avoiding catastrophic internal electrostatic discharge in dielectrics during space missions. This software package enables the simulation of carrier mobility for any given site concentration, which is a material design...

The current software has been developed to work on NASA instrument datasets, an upgrade over similar software that only worked on datasets from climate model output. NASA is attempting to reformat satellite data to fit the specific and highly detailed data format and metadata requirements for CMIP5...

A previously created direct numerical simulation (DNS) database of mixing of species under supercritical pressure has been examined and analyzed for the purpose of understanding the modeling requirements in the context of large eddy...

A Fault Detection, Isolation and Recovery (FDIR) system needs some internal concept of how the monitored system operates. This “operating concept” needs mathematical logic to represent the cause and effect relationship between constituent components of the system,...

Available guidance approaches for large numbers (i.e., swarms) of artificial agents are currently very limited. Swarms in nature (e.g., bees, birds, ants) typically contain hundreds to thousands of agents. The problem is how to mimic nature, and develop guidance laws for artificial (manmade)...

In the United States, as many as 7,000 commercial and private aircraft may be in the air simultaneously at any given time and date, and the total number of commercial flights in a given 24-hour period generally exceeds 50,000. To maintain the safety and efficiency of air travel, this innovation...

DAPS was designed to support the DAWN-AIR project participating in the Genesis and Rapid Intensification Processes (GRIP) hurricane campaign. It controls the data acquisition system consisting of a scanner that directs the lidar beam, an inertial navigation system/GPS (INS/GPS) unit for monitoring...

The Debris & ICE Mapping Analysis Tool (DIMAT) system is a Web-based system that supports communication, data integration, data sharing, and problem definition/resolution through use of an integrated presentation framework for ice and debris description and analysis. It provides an integrated...

This lidar data fusion approach is based on associating samples from sparse lidar data with groups of region objects determined by a unique image segmentation approach, HSeg (Hierar - chical Segmentation). This segmentation approach, which was previously developed by...

Driving loads such as electric motors, relay coils, and solenoids requires a relatively large initial pull-in or start-up current from a driver in order to initiate operation of the load. To maintain continuous operation, the hold or running operating current required for a load may be 20%...

The invention is a radio frequency identity detector (RFID)-based system that assists a user in location of an item, in response to an electronic query for the status of the item. The item(s) being sought may be a book on a library shelf, an item from a store inventory, a legal or financial document, a medical...

Ionizing radiation has a detrimental effect on digital electronics that need to operate in extraterrestrial environments. As space missions become longer and more complex, there is a need for flight computers that can withstand harsh radiation environments...

This software reduces the workload of the mission manager by distributing selected aircraft data to the various investigators onboard the aircraft so they do not have to continuously request the data updates. This system will then send the investigator’s comments and observations that were previously written in notebooks to a server...

ACT is able to provide insight into acquisition, operational, and life-cycle affordability early in program formulation prior to a commitment of architecture, or anytime during the program to change systems or subsystems. ACT analyzes different systems or architecture configurations for affordability that...

A feature-added, interactive version of the video release entitled “Ascent” was developed. The software version contains the full HD (high definition) movie along with extra scenes, still imagery, a movie trailer, and producer notes. The software has been packed as an iOS app, intended for use on...

This iPhone/iPad application allows the general public to access information about the Cassini mission. It enables viewing of the latest images released by the mission, allows access to images that describe the present position of the spacecraft, and provides flyby countdowns for each targeted flyby.

(LWWE) is a cross-platform server that provides support for automation and orchestration of task execution.

A computer program implements a model of the performance of the CheMin (Chemistry and Mineralogy) instrument — a miniaturized instrument that simultaneously performs x-ray diffraction (XRD) and x-ray fluorescence (XRF) measurements on small material samples. The CheMin instrument is being...

This software specializes in discovering the location and intrinsic parameters of an imaging camera when such information was not recorded in the metadata of an image. It provides a simple command line interface for specifying the input and output for the two camera perspectives.

Software has been developed that mitigates anomalously low CO2 retrieval values, due to low-lying clouds, for improved CO2 sensing accuracy. Using machine learning techniques, hand-labeled data was used to train intelligently a multivariate...
