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...

Zinc-based batteries offer a safe, inexpensive alternative to fire-prone lithium-based batteries, yet have been historically limited by poor rechargeability. A 3D zinc (Zn) “sponge” electrode architecture was developed comprising interpenetrating networks of Zn...

The focus of this research was the design, optimization, and measurement of a monotonically profiled, smooth-walled scalar feedhorn with a diffraction-limited ~14° FWHM (full width at half maximum). It is an easier-to-manufacture, smooth-walled feed that...

There are many known methods of retransmitting radio wave signals intra-building and inter-building, as well as ground-to-aircraft or ground-to-satellite. Some techniques modulate the reflection coefficient of an antenna. Prior art has used frequency multiplication or field effect transistor (FET) mixing to modulate the...

The LTAS Source Slaving Selector application was developed to transmit LTAS data in User Datagram Protocol (UDP) packets using the LTAS data from one of multiple incoming UDP streams. Users select the data stream via a graphical user interface (GUI), which also displays a...

Currently, APET includes a modified version of the Rotorcraft Noise Model (RNM, version 7). It also includes the newly developed Spectral Attenuation Method (SAM), which contains the Ray Tracing Program (RTP) and two versions of a Green's Function Parabolic Equation (GFPE) code. The third component...

AUTONOMIE is a MATLAB-based software environment and framework for automotive control system design, simulation, and analysis. It simulates subsystems, systems, or an entire vehicle, and predicts and analyzes fuel efficiency and performance. The software performs analyses and tests for virtual...

One of the objectives of the In-Situ Resource Utilization (ISRU) RESOLVE project was to extract water from lunar regolith by heating and then capturing and quantifying the released water. A potentially large error in...

This innovation addresses several critical issues in the construction of cut control volumes using embedded-boundary Cartesian mesh generators. The innovation considers the case of a surface triangulation intersecting the face of a Cartesian hex...

The purpose of the GPS Satellite Geometry Analysis Tool (GPSGEM) is to evaluate GPS satellite geometry for a given Earth-fixed location or for a provided trajectory. The tool will generate a listing of all satellites in view, the best satellite combination defined by the most optimum Geometric Dilution...
