Numerous machine learning frameworks exist, each with highly variable support for accelerated computing (e.g. Graphics Processing Units (GPUs), Field-Programmable Gate Arrays (FPGAs), etc). A library of machine learning primitives could support the many disparate frameworks and boost the advancement of machine learning research and programs, such as those underway in the DARPA Data-Driven Discover ...

The objective of this proposal is the development and demonstration of a cost-effective high-fidelity aeroacoustic design tool for future commercial supersonic nozzle designs and installations. Although eddy-resolving CFD methods for computing high-speed jet noise are available, such methods are computationally expensive and are currently deemed impractical for use in a design optimization loop. ...

The concept describes a booster for a launch vehicle that is simpler to make, transport and launch than current launch vehicles. It is composed of two major components. The first being a booster structure and the second being a liquid rocket engine that uses a thermodynamic cycle that is a combination of two common cycles.Furthermore, the engine is actually fairly simple when compared to modern li ...

Delay/Disruption Tolerant Networking (DTN) is a communication routing protocol designed specifically for high-latency applications wherein relay nodes on a multi-hop network may appear and reappear at irregular intervals. Unlike more ubiquitous TCP/IP network communications protocols that depend on known and “always on” routing paths, DTN is well suited to space-to-space applications where ind ...

A receiver system for use in LIDAR consisting of an optical filter and optical spectrometer based upon two-photon absorption is proposed. The filter and spectrometer both use dispersion from excited state transitions of atomic rubidium to create a birefringent medium. The birefringent medium of the optical filter rotates the polarization of light so that it is transmitted through crossed polariz ...

A life support systems’ reliability and survivability are critical to NASA especially in long-term space exploration missions. The Health Management of life support systems consists of several components among which power, water recovery, and biomass processing systems etc. which are of primary importance. Due to the crew’s critical dependence on such a complex system, the health management of ...

One of the primary shortcomings identified during the NASA sponsored CFD Vision 2030 Study conducted during 2012-2014 was that the generation of meshes suitable for CFD simulations constitutes a principal bottleneck in the workflow process as it requires significant human intervention. Our solution to this problem is the development of HeldenSurface, which is a robust tool for automatially conver ...
