Direct Solve Image-Based Wavefront SensingGSC-15208-1This technology solves for the wavefront directly from a single image and does not require defocusing or anonlinear iterative algorithm.U.S. Government Purpose ReleaseDthData Armstrong Time-History Software UtilityA standalone command-line-driven utility program, DthData processes time-history format data filesgenerated by the Armstrong Core Simulation Software.U.S. Release OnlyDthDiff Armstrong Time-History Difference Software UtilityDRC-012-024DRC-012-025A standalone command-line-driven utility program, DthDiff is used to compare two Armstrong time-historyformat data files generated by the Armstrong Core Simulation Software.U.S. Release OnlyElimination of Parameter Input Requirement forElliptic Grid Generation Methods in EngineeringThis software implements an enhanced method of elliptic grid generation.U.S. Government Purpose ReleaseARC-14710-1Empirical Mode Decomposition Method and Hilbert Spectral Analysis AlgorithmsGSC-13817-1This software enables computer-implemented physical signal analysis and associated presentation techniquesof results. It uses an empirical mode decomposition to extract a collection of intrinsic mode functions (IMFs)from nonlinear, nonstationary physical signals. IMFs can be used to calculate instantaneous frequencies. Thissoftware can localize any event on a time and frequency axis.U.S. Government Purpose ReleaseEnhanced Graphics for Extended Scale RangeGSC-14819-1Conventional computer graphics algorithms exhibit anomalies when rendering scenes containing simultaneouslydisplayed objects differing enormously in scale and distance from the viewer. The Extended ScaleRange software employs a dynamic repartitioning of the distance scales of scene objects during renderingto eliminate almost all such problems in a way compatible with implementation in software, in vertex andpixel shaders, and in hardware accelerators.U.S. Government Purpose ReleaseEstimated Spectrum Adaptive Postfilter (ESAP)and the Iterative Prepost Filtering (IPF) AlgorithmsGSC-14213-1These algorithms provide new frequency-based, pixel-adaptive filtering for low-bit-rate JPEG-format imagesand MPEG-format video. The Estimated Spectrum Adaptive Postfilter (ESAP) and the Iterative PrepostFiltering (IPF) algorithms significantly reduce the blocking artifacts resulting from high compression byreusing the discrete cosine transform coefficient local frequency characteristics to control a pixel-adaptivenonlinear post-filter (or “pre-post”) filtering system.U.S. Release OnlyEthernet-to-HRDL Conversion DesignGSC-16513-1The International Space Station (ISS) uses a fiber-optic High Rate Data Link (HRDL) standard for transferringdata. Those designing ISS experiments, however, may prefer an Ethernet interface. This design allows ISSinstruments to keep their Ethernet interface by converting the Ethernet data format into a format compatiblewith the ISS.U.S. Government Purpose Release14.
