3D Volumetric Display Technology

The United States government spends a lot of money on its defense programs, investing in the training and technology necessary to arm and prepare the most advanced fighting force on the planet. The price tag for these efforts reached $581 billion in 20141 as various branches of defense continued to dedicate funds toward the research and development of innovative tools and technology.

Predictive Computations of Single-Phase Turbulent Flows

Explicitly filtered large-eddy simulation is used. NASA’s Jet Propulsion Laboratory, Pasadena, California This software computes a single-phase turbulent flow. The solution is independent of the grid spacing on which it is computed, and on the discretization order used for the differential equations. Grid spacing and discretization-order independence can be achieved by reformulating the large-eddy simulation (LES) equations. Previous software followed the conventional LES equations, whereas the present one follows the explicitly filtered formulation (EFLES).

Predictive Computation of Two-Phase Turbulent Flows with Phase Change

Explicitly filtered large-eddy simulation is used. This software computes two-phase turbulent flows with phase change, and the solution is independent of the grid spacing on which it is computed and on the discretization order used for the differential equations. Grid spacing and discretization-order independence can be achieved by reformulating the large-eddy simulation (LES) equations. Previous software followed the conventional LES equations, whereas the present one follows the explicitly filtered formulation (EFLES).

Physics-Model-Based Wiring Fault Detection Toolbox for MATLAB

Ames Research Center, Moffett Field, California This software provides a toolbox of MATLAB functions for detecting precursor wiring faults, such as chafing, in shielded impedance-controlled cable using measurements from off-the-shelf time domain reflectometry or vector network analyzer hardware. It advances the state-of-the-art in wiring fault detection, currently limited to the detection of hard opens or shorts, by combining high-fidelity analytical physics models for signal propagation on faulty cable with fast Bayesian inference algorithms for intrinsic cable and fault parameter retrieval. The overall approach is robust to noisy operating conditions, and does not require fixed baseline measurements. More information about this software can be found at: http://ti.arc.nasa.gov/project/wiring.
