One cannot build a system-level Prognosis and Health Management (PHM) solution by cobbling together a bunch of existing prognostic techniques; it will have a very high rate of false-positive indications. On the other hand, if a system-level health management solution could identify the individual degradations and indictors associated with those degradations, and thereby decouple the problem into smaller pieces, the existing prognostic techniques could still be used to predict time to failure, and could therefore drive an effective Condition Based Maintenance and Decision Support System (CBM+). Qualtech Systems, Inc. (QSI) and Vanderbilt University team seeks to develop a system-level diagnostic and prognostic process and a "sense and respond capability" which first uses error codes and discrete sensor values to correctly diagnose the system health including degradations and failures of sensors and components, and then invoke appropriate prognostic routines for assessment of remaining life and capability. Thus, QSI's Testability Engineering And Maintenance System (TEAMS) real-time reasoner will enable the use of many existing prognostics techniques in the broader context by decomposing the complex system into local datasets of degradations and associated sensor data sets, thereby limiting the problem-space for the prognostic techniques to their limited design scope. Indeed, it is well established in the contexts of parameter estimation and model-based fault identification (i.e., fault isolation and severity estimation) that feature selection and diagnosis, respectively, followed by parameter estimation provides major improvements in estimation performance (measured in terms of computational time as well as the standard deviations of the estimated parameters) when compared to full parameter estimation which provides biased estimates for all the parameters.

It is accepted that adaptive aerospace vehicles whose flight avionic systems are reconfigurable are needed to respond to changing flight parameters, vehicle system performance degradation, or external threat environments. To this end shape modification of aerospace structures during flight can provide significant performance improvements derived from matching the aerodynamic shape to particular flight conditions. To address this need, new sensor technologies are required for both R & D testing and operational deployment that permit high observability into the shapes generated. Luna Innovations proposes to develop high-spatial resolution distributed fiber-optic shape sensors to provide feedback as part of a closed-loop control system for vehicles with yadaptivey attributes (i.e. y ysmarty wings, etc.). These shape sensors, when embedded in aircraft wings or other structures of interest, will monitor the dynamic shape of the structure independent of the temperature or load environment, thus enabling real-time active control of reconfigurable avionics. By providing a reliable, low cost, lightweight feedback mechanism, the risks associated with employing smart vehicle technology are substantially mitigated.

Forecasting the Impact of Storm Waves and Sea-Level Rise on Midway Atoll and Laysan Island within the Papahanaumokuakea Marine National Monument - A Comparison of Passive Versus Dynamic Inundation Models
Published By US Fish and Wildlife Service, Department of the Interior

Summary
Description
Two inundation events in 2011 underscored the potential for elevated water levels to damage infrastructure and affect terrestrial ecosystems on the lowlying Northwestern Hawaiian Islands in the Papahnaumokukea Marine National Monument. The goal of this study was to compare passive bathtub inundation models based on geographic information systems GIS to those that include dynamic water levels caused by waveinduced setup and runup for two endmember island morphologies: Midway, a classic atoll with islands on the shallow 28 m atoll rim and a deep, central lagoon; and Laysan, which is characterized by a deep 2030 m atoll rim and an island at the center of the atoll. Vulnerability to elevated water levels was assessed using hindcast wind and wave data to drive coupled physicsbased numerical wave, current, and waterlevel models for the atolls. The resulting model data were then used to compute runup elevations using a parametric runup equation under both present conditions and future sealevelrise scenarios. In both geomorphologies, wave heights and wavelengths adjacent to the island shorelines increased more than three times and four times, respectively, with increasing values of sealevel rise, as more deepwater wave energy could propagate over the atoll rim and larger winddriven waves could develop on the atoll. Although these increases in water depth resulted in decreased setup along the islands shorelines, the larger wave heights and longer wavelengths due to sealevel rise increased the resulting waveinduced runup. Runup values were spatially heterogeneous and dependent on the direction of incident wave direction, bathymetry, and island configuration. Island inundation was modeled to increase substantially when wavedriven effects were included, suggesting that inundation and impacts to infrastructure and terrestrial habitats will occur at lower values of predicted sealevel rise, and thus sooner in the 21st century, than suggested by passive GISbased bathtub inundation models. Lastly, observations and the modeling results suggest that classic atolls with islands on a shallow atoll rim are more susceptible to the combined effects of sealevel rise and wavedriven inundation than atolls characterized by a deep atoll rim.

An important mission for NASA is the development of revolutionary flight concepts and technology. The development of Micro unmanned air vehicles (Micro-UAVs) and Mars aircraft has received considerable attention in recent years. Unlike conventional aircraft and UAVs, Micro-UAVs and Mars aircraft suffer from operation in an extremely low Reynolds number flight regime. Both Micro-UAVs and Mars aircraft can have operational Reynolds number regimes from 20,000 to 120,000. At these extremely low Reynolds numbers, the aerodynamic flow features are dominated by laminar separation and separation bubble effects, which are the primary source of poor performance in both drag and maximum lift for this class of vehicles. It is proposed to use a robust and powerful active transition fixing technique to eliminate the effects of these large separation bubbles and provide revolutionary performance as of yet unobtainable by this class of ultra low Reynolds number vehicles. By artificially transitioning the flow upstream of the laminar separation bubble, the bubble itself can be eliminated resulting in a greatly reduced drag. The increased resistance to separation of a simple turbulent boundary-layer can pay revolutionary dividends at these very low Reynolds numbers.

Since 1995, the Lincoln Space Surveillance Complex in Westford, Massachusetts, has played a key role in space situational awareness and the Laboratory's overall space surveillance mission. The site comprises three major radars - Millstone Deep-Space Tracking Radar (an L-band radar), Haystack Long-Range Imaging Radar (X-band), and the Haystack Auxiliary Radar (Ku-band). The Millstone Hill Radar, a high-power L-band radar, is used for tracking space vehicles and space debris and plays a key role in the national deep-space surveillance program. A broad-based observatory capable of addressing a wide range of atmospheric science investigations, Millstone Hill has evolved over the past two decades in keeping with the space surveillance community's recommendations and support. As a contributing sensor to the Space Surveillance Network, the Millstone Hill Radar provides approximately 18,000 deep-space satellite tracks per year and coverage for almost all deep space launches, including premission planning, radar coverage of critical events, and searches. The Millstone Radar has been operating since 1957, when it successfully detected the Soviet Sputnik satellite. The Haystack Ultrawideband Satellite Imaging Radar (HUSIR) is a dual-band (X and W) radar. Like Millstone, HUSIR is also a contributing sensor to the U.S. Space Surveillance Network, collecting imaging and metric data on space objects. It also collects data to assist NASA in developing models for orbital space debris. The exquisitely accurate surface of the HUSIR 120-foot-diameter antenna that enables W-band radar operation makes it also a valuable instrument for radio astronomy. HUSIR is available for use by the MIT Haystack Observatory as a radio-telescope to conduct single-dish radio astronomy and very-long-baseline interferometry experiments. Haystack's research facilities are used in various educational programs for graduate, undergraduate, and pre-college students. The Haystack Auxiliary Radar (HAX) was built in 1993 by Lincoln Laboratory to augment satellite imaging and space-debris data collections. It is a Ku-band radar with its own 40-foot antenna. The combination of Haystack and HAX radars provides year-round availability for U.S. Strategic Command imaging requirements. In 2014, the Haystack facility marked its 50th year of operation. A commemorative booklet tracing the history of the facility highlights how Haystack has enabled both scientific measurements made by astronomers at MIT Haystack Observatory and contributions to space surveillance made by Lincoln Laboratory staff.
