Description
ZONA Technology (ZONA) proposes to develop an enhanced model updating nonlinear system identification (MUNSID) methodology that utilizes flight data with state-of-the-art control oriented techniques. The MUNSID toolbox augments the current match-point solution approach using the mu-analysis method with identified nonlinear operators. The procedure calls for a high-fidelity linear aeroelastic model to be tuned quickly with available aeroelastic/aeroservoelastic flight data sets, while block-oriented models are used to highlight the underlying nonlinear structure of the dynamic system. This framework is capable of accounting for several nonlinearities including those due to aerodynamics, structures, control/actuator, and/or geometry. Specifically, this on-line Flutter/LCO predictor can be used to accurately estimate a supercritical LCO case if the global nonlinear dynamic behavior is described throughout a hardening nonlinearity, as well as a more dangerous dynamic behavior, denoted as subcritical LCO, could be developed if a global softening nonlinearity is identified. The devised MUNSID Toolbox will become the flight control engineer's "every day tool" to predict on-line Flutter/LCO phenomena. In Phase II, MUNSID will be updated with fast and computationally efficient routines for system modeling, LFT representation, identification of nonlinearity, estimation of uncertainty, and stability analysis. Deliverables include the MUNSID production software including a GUI, a library of S-functions, and the related user manuals.

The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

Digital data sets that describe aquifer characteristics of the Rush Springs aquifer in western Oklahoma

Summary
Description
This data set consists of digitized polygons of constant hydraulic conductivity values for the Rush Springs aquifer in western Oklahoma. This area encompasses all or part of Blaine, Caddo, Canadian, Comanche, Custer, Dewey, Grady, Stephens, and Washita Counties. For the purposes of modeling the ground-water flow in the Rush Springs aquifer, Mark F. Becker (U.S. Geological Survey, written commun., 1997) defined the Rush Springs aquifer to include the Rush Springs Formation, alluvial and terrace deposits along major streams, and parts of the Marlow Formations, particularly in the eastern part of the aquifer boundary area. The Permian-age Rush Springs Formation consists of highly cross-bedded sandstone with some interbedded dolomite and gypsum. The Rush Springs Formation is overlain by Quaternary-age alluvial and terrace deposits that consist of unconsolidated clay, silt, sand, and gravel. The Rush Springs Formation is underlain by the Permian-age Marlow Formation that consists of interbedded sandstones, siltstones, mudstones, gypsum-anhydrite, and dolomite beds (Mark F. Becker, written commun., 1997). The parts of the Marlow Formation that have high permeability and porosity are where the Marlow Formation is included as part of the Rush Springs aquifer. The Rush Springs aquifer underlies about 2,400 square miles of western Oklahoma and is an important source of water for irrigation, livestock, industrial, municipal, and domestic use. Irrigation wells are reported to have well yields greater than 1,000 gallons per minute (Mark F. Becker, written commun., 1997). The hydraulic conductivity values used by Mark F. Becker (written commun., 1997) to simulate the ground-water flow in the Rush Springs aquifer are 0.8, 2.0, 4.0, 8.0, and 10.0 feet per day. The hydraulic conductivity values are based on specific capacity data and aquifer tests. Mark F. Becker created some of the hydraulic conductivity data set by digitizing parts of previously published surficial geology maps. Ground-water flow models are numerical representations that simplify and aggregate natural systems. Models are not unique; different combinations of aquifer characteristics may produce similar results. Therefore, values of hydraulic conductivity used in the model and presented in this data set are not precise, but are within a reasonable range when compared to independently collected data.

This point file displays the 525 field plot and observation locations visited in 2003 and 2004 as part of the vegetation mapping project for Colorado National Monument. The data collected were used for the vegetation classification and mapping of the park. Sample plots were located subjectively in representative vegetation throughout the Monument. A map of soils and geology overlain on topography helped field crews maximize the diversity of sites sampled. Field crews decided where and when to use observation points or vegetation plots to sample the vegetation. Vegetation plots were placed in stands judged by field crews to represent legitimate vegetation types that could be classified to the NVC using standard multivariate analysis techniques. Observation points were placed in stands (1) if the vegetation was highly altered and therefore not classifiable, (2) to provide information about the distribution of common vegetation types adequately sampled in vegetation plots, or (3) if the stand represented a unique vegetation type that was too small to hold a 400m2 sample plot (e.g., seeps, Oregon grape shrubland). Fuels data was collected at a subset of the plots visited, and 360 degree movie files were taken of the vegetation. Nine hundred and twenty photographs were also taken of plot and observation locations.
Behavior and fate of spilled Prudhoe crude upon the Atigun River flood plain: Phase II, August 6-7 field assessment
Published By US Fish and Wildlife Service, Department of the Interior
Issued about 9 years ago
Summary
Description
Observations obtained during the August 6th 7th field surveys are part of the continuing assessment of the fate and effects of spilled Prudhoe crude upon the Atigun Flood Plain system. The continuing field assessments are performed as per the intents of Phase III and IV of the National and Regional Pollution Response Contingency Plans. The June 1920 and 2628, 1979 field assessment survey showed that a large amount of oil had become entrapped within the flood plain sediments and root masses of riparian vegetation. The August field survey was aimed at: 1 determining the extent of the flood plain still affected by stored oil; 2 determining the level of threat the stored oil could still pose or could continue to pose to the habitatfish and wildlife resources of the Atigun Flood Plain; and 3 determining if continuation or modification of spill containments and cleanup activities were still mandated.

Summary
Description
The size and accuracy specifications of telescope mirrors are ever more demanding. This is particularly true for secondary mirrors, as they are convex and thus require large-aperture optics to test them. Recent NASA programs, such as the Terrestrial Planet Finder (TPF) and James Webb Space Telescope (JWST), include monolithic secondary mirrors of significant size (larger than half a meter). Secondary mirrors of such large sizes are difficult and expensive to test due to the large-aperture converging and nulling optics required. Furthermore, calibration of these optics to the level required for next-generation programs is extremely challenging. Subaperture stitching has the potential to provide accurate high-resolution maps of large-aperture aspheric optics without the use of even larger aperture optics or dedicated nulls. QED's Subaperture Stitching Interferometer (SSI<SUP>REG</SUP>) has achieved nanometer-level accuracies on spherical optics with its novel compensation techniques. Non-null capability is enhanced since the individual subapertures have significantly less aspheric departure. However, the system is currently only capable of testing up to 280 mm optics of mild asphericity. Phase I work demonstrated that the technology is scalable to larger aperture sizes. This proposal focuses on innovations for leveraging the considerable benefits of stitching (high resolution, automatic calibration, and flexible aspheric testing) to aspheric optics. Activities will include uncertainty analyses of aspheric tests, subscale measurement demonstrations, and development of concepts for testing larger amounts of aspheric departure.
