nu-Anomica (Previously Sparse One Class Support Vector Machines (SOC-SVMs))
nu-Anomica is an anomaly detector that can run faster than traditional OC-SVMs. The technology can handle large training sets and works with a well-defined target function. The program utilizes the OSU SVMs code (which is a MATLAB version of Lib-SVMs) as the baseline.

Extendable Uniform Remote Operations Planning Architecture (EUROPA) 2.1
EUROPA is a general-purpose, reusable, artificial intelligence software system. The tool generates plans for performing complex activities in parallel. Functionality includes the capability of verifying that a plan satisfies all constraints.

Swim: A Software Information Metacatalog for the Grid
Swim is a software information service for the grid built on top of the NASA-developed Pour framework. Software information is periodically gathered from native package managers on FreeBSD, Solaris, and IRIX as well as the RPM, Perl, and Python package managers on multiple platforms.

Command, Control, Communications, and Intelligence (C3I)Delay/Disruption-Tolerant (DTN) Networking Software
This code is a DTN implementation of the Constellation Program's C3I software.
U.S. Government Purpose Release
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.
U.S. Release Only
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
CSPAN Axial-Flow Compressor Conceptual Design Code
This span-line analysis technology uses isentropic simple radial equilibrium to determine a flow path.
U.S. Government Purpose Release
Computational Fluid Dynamics (CFD) Seal Analysis Code
This technology is a computer program designed for the study of fluid dynamic forces.
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).
