APPS provides a multi-mission instrument data and metadata (i.e. label) transformation service that interfaces local or remote Mission Data provider’s data processing pipeline/end-products and the PDS (Planetary Data System) data archive to ensure compliance to standards in a schedule/cost-efficient manner (i.e....

The purpose of the Desktop Status application is to collect processor, memory, and storage usages of a computer running the Microsoft Windows 7 operating system, and record these data with time stamps to files at a user-defined time interval. A graphical user interface (GUI) captures users' inputs and displays them on a plot for...

The ScienceOrganizer system was designed to facilitate the work of geographically distributed NASA science teams by supporting the organization, administration, documentation, and execution of science projects and missions. The capabilities of ScienceOrganizer...

The Knowledge Preservation Management (KPM) system allows for the capture, management, and Web-based access of manufacturing operations information. KPM also captures retirees' knowledge via transcript-enabled video-taped interviews, and with video data-mining advanced search capabilities. Access to this...

Virtually all NASA spacecraft use composite overwrapped pressure vessels (COPVs) to reduce the weight disadvantage of metal pressure vessels. However, these composite structures are more susceptible to damage than metal PVs, are difficult to inspect,...

Over the past several decades, one class of problems in computational fluid dynamics (CFD) that has undergone substantial development involves movement of the fluid domain boundary. The problem class exists when the fluid domain boundary is either explicitly time-dependent, or is known a priori and...

The simulation of high-speed flow involves unique challenges such as the treatment of strong flow gradients associated with shock waves and expansion fans, as well as the modeling, at hypersonic speeds, of air chemistry effects. However,...

ARC2D is a computational fluid dynamics (CFD) program for two-dimensional airfoil and simply connected geometries. The program uses implicit finite-difference techniques to solve two-dimensional Euler equations and Navier-Stokes equations. It is based on the Beam and Warning...

To produce accurate system architecture descriptions, it is essential to be able to describe interfaces between system elements at different levels of abstraction and from different perspectives at the same time. For example, the connection from system A to system B may be viewed at a high level as...

Pegasus software is used as a pre-processor for overset-grid Computational Fluid Dynamics (CFD) simulations. It provides the hole-cutting and connectivity information between structured overset grids. The main features of the software include automated hole-cutting algorithms, a...

It can be very useful to know about activities among individuals; for example, which individuals are associated with other individuals? When two or more individuals get together, is there an intended purpose? Who are the leaders or important individuals of a group? What is the organizational...

When designing or analyzing electrical systems, it is important to understand the relationship between input and output. Power conversion occurs in a “black box,” and transfer functions can be used to provide a better understanding of the processes occurring in this black box. Although they provide a useful...

This object-oriented Python module facilitates precipitation retrievals (e.g., hydrometeor type, precipitation rate, precipitation mass, particle size distribution) from polarimetric radar data. It leverages existing open-source radar software packages to perform all-in-one retrievals that are...

Interest in the simulation of acoustic environments has prompted a number of technology development efforts over the years for applications such as auralization of concert halls and listening rooms, spatial information displays in aviation, virtual reality, and better sound effects for video games. Each of these...

In general, and especially in the “big data” era, there is often a failure to collect sufficient data about the data (metadata). This lack of metadata drastically reduces the potential use of the data, and the attempt to rectify this situation after the fact is often difficult, if not...

Methods exist for processing an original data sequence in order to generate information about the data for the purposes of integrity measurement, ownership demonstration, and authentication. The first category is digital watermarking, the second is data hashing, and the third is error detection...

Anew network protocol — the Multi Node Label Routing (MNLR) protocol — was developed to improve the information flow between emergency responders at the scene of an incident and decision-makers at the office of emergency management.

A reporting tool was needed that could indicate the accuracy of search results by tracking the number of clicks required by users to find their desired search results. The application should also capture the number of times other links and like filtering components are clicked. The report should have the...

Android is the primary software platform for mobile, networked devices such as tablets and smartphones. These devices are increasingly used for safety-critical functions that require verification of correct and robust behavior of applications. Such software written for the Android operating system is hard to test because applications are...

Google Maps and Google Earth allow the development of customized displays, but such displays must be constructed by a software developer. The Flood Dashboard allows non-technical users to utilize a simple Web form to build and present custom displays. It is a Ruby on Rails 4 application that allows users to build custom...

A typical data warehouse may contain thousands of tables. Validating the data quality of all data warehouse content is an unmanageable and unmaintainable task if handled in an ad-hoc fashion. This software seeks to ensure that a data warehouse accurately reflects the...

PLOT3D is an interactive graphics program designed to help scientists visualize computational fluid dynamics (CFD) grids and solutions. Today, supercomputers and CFD algorithms can provide scientists with simulations of such highly complex phenomena that obtaining an understanding of the simulations has become a major problem. Tools that...
