Mimosa Acoustics will develop a portable binaural audiological device, based on our successful HearID system. HearID is a clinical system for otoacoustic emission and middle-ear power analysis testing; it is FDA and CE-marked. The new system will have the ability to conduct a variety of audiological tests especially for use in hearing-conservation programs, including: flexible otoacoustic emission ...

In most critical software systems, a state that is partially visible through values passed across interfaces contains information that could determine the health of the software system, and whether a failure is likely in the future. Some of this information behaves in a continuous fashion, e.g., the available memory or disk space is easily interpreted to monitor system health. Other values are nom ...

The technical objective of this project is to develop a prototype of a face recognition application in a cloud computing environment utilizing MBARK as the middleware. The application will have a client piece that will run on a mobile device such as a laptop and a server piece that will run on a higher-performance computing cluster. The specific objectives of this development project can be enumer ...

Current toxicity testing of foodstuffs involves mass spectrometry analysis which requires a>24 h turnaround time in deployed military operations. This length of time is dangerous for personnel. Rapid identification of toxic industrial chemicals (TICs) in food using a sensor that is biologically-based and easy to use eliminates that danger and would provide exactly what is needed for toxicity eva ...

Fault-Tolerant Control (FTC) is an emerging area of engineering and scientific research that integrates prognostics, health management concepts and intelligent control. Impact Technologies and the Georgia Institute of Technology, propose to build off of a strong foundation in fault-tolerant control (FTC) research performed with NASA in past years to mature the applicability of this technology and ...

This NASA Phase II STTR effort will develop domain-engineered magnesium oxide doped lithium niobate (MgO:LN) for LIDAR-based remote sensing and communication applications. Use of bulk and waveguide-based domain engineered MgO:LN will allow the manufacture of highly efficient and compact, wavelength conversion modules for second-harmonic generation (SHG), sum-frequency generation (SFG), and parame ...

Propagation of parameter uncertainties through large computer models can be very resource intensive. Frameworks and tools for uncertainty quantification are generally geared to individual codes, are research codes, or are single-purpose tools such as LHS matrix generators. The Reduced-Order-Clustering-Uncertainty-Quantification (ROCUQ) methodology discussed in this proposal is specifically designe ...

The ability to quickly and reliably simulate high-speed flows over a wide range of geometrically complex configurations is critical to many of NASA's missions. Advances in CFD methods and parallel computing have provided NASA the core flow solvers to perform these simulations. However, the ease of use of these flow solvers and the reliability of the results obtained are a strong function of t ...

The work will focus on the 3D implementation of the Phase 1 CHARM mesher, with solution-adaptive iteration for CFD and non-CFD applications. The proposed 3D method will incorporate and extend a previously developed method of generating field-guided hexahedral elements from a metric tensor field. While the fundamental technical approach?a combination of metric tensor conditioning, metric-tracing me ...

The control of pain, anxiety, discomfort, and the sequellae of injury and illness is an over-arching healthcare issue in both military and civilian settings. Current strategies for pain relief, sedation and anesthesia involve infusion of intravenous agen
