Single Board Computer System Monitoring Software for Radiation Testing
This software package uses simple Python scripts to assess computer performance. This is specifically intended to be used on Single Board Computers for monitoring system parameters during radiation testing. This is hoped to provide a powerful, flexible framework that can be rapidly deployed on a variety of systems (Windows/Linux, Intel/ARM) and can serve as a common community benchmark for a radiation testing Single Board Computers.

Channel Emulator
The Channel Emulator (CE) is a software-based network testing tool. Its primary functions are providing data framing services, acting as a flexible protocol gateway, and providing network emulation capabilities. The software caneasily accept one protocol, optionally extract the payload, send out as different protocol, or encapsulate one in another. It can also introduce delays up to deep space levels, and introduce bit errors and other link degradations.

LEWICE 3.2.3 Ice Accretion Software
LEWICE contains an analytical ice accretion model that evaluates the freezing process thermodynamics that occur when super-cooled droplets impinge on a body. Both atmospheric parameters (i.e., temperature, pressure, and velocity) and meteorological parameters (i.e., liquid water content, droplet diameter, and relative humidity) are used to determine the shape of the ice accretion.
U.S. Release Only
The PMESH grid-generation program produces three-dimensional blade-passage meshes for the computational fluid dynamics (CFD) modeling of advanced single- or counter-rotation turboprops and propfans.

Tone Fan Noise Design/Prediction System (TFaNS 1.5)
TFaNS predicts tone noise emanating from a fan stage, including the effects of reflection and transmission by the rotor and stator and by the duct inlet and nozzle. Version 1.5 upgrades include: the SOURCE3D subprogram's ability to perform transmission-loss calculation for modes scattering into themselves; the inlet and aft radiation codes' use of infinite envelope elements in the far-field; and the AWAKEN subprogram's use of a new Acoustic Wake/Turbulence File format.
U.S. Release Only
Jet Noise Prediction Code (JeNo 2.5D)
JeNo is a Fortran 90 computer code that evaluates the far-field turbulence-generated noise in non-axisymmetric jets. The propagation Green's function is calculated along a user-specified azimuthal angle (line of sight), but source volume integration is carried out in 3D. The user must provide a structured computational grid in a polar coordinate system and also input a mean flow solution from a Reynolds-Averaged Navier Stokes (RANS).
U.S. Release Only
WOPWOP is used for helicopter main-rotor noise prediction. The user must input measured air loads.
U.S. Release Only
HemoDose Software, Version 2.0
HemoDose estimates the absorbed dose of radiation in adults by using single or serial counts of granulocyte, lymphocyte, leukocyte, or platelet after exposure.
General Public Release
This NASA-developed technology is a MATLAB-language computer program for exploratory data analysis. Through the fast post-processing of measured time-series Raman spectral data, RAT-EDA reveals thermo-chemical properties and turbulent-chemistry interactions in combustion. The computer program deduces probability density functions of combustion temperatures using user-selected super-pixel regions for each major species (e.g., O2, N2, CH4, CO2, or H20).
