Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. 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 DFIRM Database is derived from 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).The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

Description

Despite the rapid commercialization of additive manufacturing technology such as selective laser melting, SLM, there are gaps in process modeling and material property prediction that contribute to slow and costly process qualification and product certification. To address these gaps, CFDRC and our partner Dr. Kevin Chou, University of Alabama, will develop multiple computationally efficient, high-fidelity simulation tools for the SLM process. During Phase I the team will apply adaptive meshing to enable efficient thermomechanical simulations for centimeter size test coupon builds, leverage existing multiphase flow models to analyze particle size effects on material variations, apply phase field models to predict microstructure evolution, and evaluate model predictions against experimental characterization. During Phase II, the modeling tools will be extended to improve computational efficiency and scalability to aerospace component dimensions by further leveraging parallel computing and other acceleration techniques. The fidelity of the models will be enhanced to better predict distortion, residual stress, microstructure and defects from process conditions; and additional process data will be used to validate the resulting codes. The resulting toolset will be capable of efficiently predicting these dimensional and microstructural properties of SLM components from process conditions, while addressing important design and build features such as overhanging sections and build supports. The high-fidelity, physics based nature of the codes will allow straightforward application to new materials, and to guiding development of and verifying analytical physics models for process control.

Description

The San Bernardino National Wildlife Refuge was established in 1982 for the protection and management of endangered desert fishes which are indigenous to the Rio Yaqui drainage. The 2,309acre refuge is located on the United StatesMexico border 16 miles east of Douglas, Arizona. Collectively, copper smelter emissions in southern Arizona and northern Sonora have a created a regional atmospheric condition where mean annual precipitation pH is 4.7 to 5.0. Background chemistries are largely unavailable and influence of both nonferrous smelter emissions and current agricultural practices and pesticide use remain unexplored. During May and June 1987 water chemistry was determined onsite at each of 13 locations within the refuge including Leslie Creek and sediment and selected tissue samples were collected for trace metals and pesticide analysis. Overall, refuge waters were virtually absent of dissolved trace metals and spring chemistries were relatively consistent due to their presumable origin from a common aquifer. Alkalinity exceeded the EPA recommended minimum of 20 mg1 for freshwater aquatic life by a factor of 10 to 18 and appears to be the mitigating factor which allows acidic deposition to adversely manifest itself in the aquatic ecosystem. Biota are probably the best integrative indicator of water shed quality, and its ability to neutralize acid. Trace metal residues in tissue matrices were mixed in their occurrence, especially for frogs. However, no evidence of acidstress in resident organisms on the refuge was observed. Native fish populations exhibited no symptoms of lack of recruitment, incidence of morphological abnormalities, or subnormal growth. Likewise, bullfrogs flourish throughout the refuge and exhibited little in regard to trace metal body burdens. Periodic biological and chemical monitoring is the recommended course of action to evaluate refuge condition and trend relative to environmental quality.

Description

Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Scheduled to launch in 2015, the mission will extend the time series of ocean surface topography measurements begun by the TOPEX/Poseidon satellite mission in 1992 and continuing through the currently operating Jason-1 (launched in 2001) and OSTM/Jason-2 (launched in 2008) missions. These measurements provide scientists with critical information about circulation patterns in the ocean and about both global and regional changes in sea level and the climate implications of a warming world. TOPEX/Poseidon and Jason-1 were cooperative missions between NASA and the French space agency, CNES. Additional partners in the Jason-2 mission included NOAA and Eumetsat. Jason-3 continues the international cooperation, with NOAA and Eumetsat leading the efforts, along with partners NASA and CNES. The primary instrument on Jason-3 is a radar altimeter. The altimeter measures sea-level variations over the global ocean with very high accuracy (as 1.3 inches or 3.3 centimeters, with a goal of achieving 1 inch or 2.5 centimeters). These auxiliary data files are used to generate Level-2 products. They include both static tabular data files and dynamic files which change/grow over time. Auxiliary files are produced outside of OSTM, but are used in product development. Filetypes in the Auxiliary data family (J3-AUX) which are produced by the European Center for Medium range Weather Forecasting (ECMWF) are restricted by ECMWF to the Jason-3 project team. Additional documentation for Jason-3 data is archived at the NODC at: https://archive.nodc.noaa.gov/cgi-bin/AMS/prod/accession/details/118276. The documentation includes metadata in International Standards Organization (ISO) format.

Description

The goal of this SBIR is to adapt an initial prototype ultra-miniature high-performance brushless-DC-motor controller, code named 'Puck', for use by NASA across a wide range of motor drives. The Puck was recently developed by Barrett for terrestrial mobile-manipulation uses where efficiency, low mass, and robustness are critical factors. While quite small (<50 grams), the controller can pump from milliamps to several amps continuous. Several features of this controller make it a candidate for NASA's wide range of needs for servomotor control in the demanding environments of extra-terrestrial and interplanetary exploration. One of the key enabling design strategies that led to the Puck is elimination of transmission lines through total integration of power conditioning, rotor-position optics, and commutation into a single tiny module. The module is small and energy efficient enough to make casting within high-heat-conduction plastic feasible. Pure conduction cooling, a distinct advantage for NASA applications, is unusual for motor amplifiers which are generally cooled by natural convection or forced air. The hermetically-sealed packaging also excludes lunar or Martian dust from affecting robustness. The primary strategy for this technology to avail for NASA will be to minimize the effects of radiation while enabling self-diagnosis, self-repair, and ultimately easy change-out.

Description

These data are qualitatively derived interpretive polygon shapefiles and selected source raster data defining surficial geology, sediment type and distribution, and physiographic zones of the sea floor from Nahant to Northern Cape Cod Bay. Much of the geophysical data used to create the interpretive layers were collected under a cooperative agreement among the Massachusetts Office of Coastal Zone Management (CZM), the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Army Corps of Engineers (USACE). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes because of natural or human effects. The project is focused on the inshore waters of coastal Massachusetts. Data collected during the mapping cooperative involving the USGS have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The interpretations released in this study are for an area extending from the southern tip of Nahant to Northern Cape Cod Bay, Massachusetts. A combination of geophysical and sample data including high resolution bathymetry and lidar, acoustic-backscatter intensity, seismic-reflection profiles, bottom photographs, and sediment samples are used to create the data interpretations. Most of the nearshore geophysical and sample data (including the bottom photographs) were collected during several cruises between 2000 and 2008. More information about the cruises and the data collected can be found at the Geologic Mapping of the Seafloor Offshore of Massachusetts Web page: http://woodshole.er.usgs.gov/project-pages/coastal_mass/.

The LAT team monitors flux values for a number of bright sources and transient sources that have shown flares during the mission. (See up-to-date weekly reports on flaring sources at the Fermi-LAT Flare Advocate Blog.) As sources cross the monitoring flux threshold of 1x10-6 cm-2s-1, they are added to the monitored source list. (The initial flux threshold was 2x10-6 cm-2s-1, but this value was lowered in June 2009.) In addition to the light curves below, the flux values in several bands are available via Browse. This list will continue to grow as the mission progresses.

Description

PS-AHAB (Puget Sound Alexandrium Harmful Algal Blooms) is a component of the NOAA ECOHAB program, focused on modeling favorable habitat areas for Alexandrium catenella in Puget Sound and evaluating the effects of climate change. The dinoflagellate Alexandrium catenella produces a suite of potent neurotoxins, collectively known as paralytic shellfish toxins (PSTs), which accumulate in shellfish and cause severe illness or death if contaminated shellfish are consumed by humans. Alexandrium catenella form dormant cysts that overwinter on the seafloor and provide the inoculum for toxic blooms the following summer when conditions become favorable again for growth of the motile cell. A 2005 survey of A. catenella cyst distribution in Puget Sound, Washington, identified seedbeds with high cyst abundances that correspond to areas where shellfish frequently attain high levels of toxin. However, even at these sites, interannual variability in the magnitude of toxic events is high. In order to provide advanced warning of A. catenella blooms, managers need to know how much seed is available to initiate blooms, where this seed is located, when/where this seed could germinate and grow, and how these factors could be altered by future climate change. Climate change impacts were assessed using present day and future maps of favorable habitat areas in Puget Sound, based on knowledge of growth rates for different temperature and salinity conditions. Present day maps will be based on hindcasts of oceanographic conditions in Puget Sound during a typical year, and future habitat maps will be created using downscaled climate change scenarios for the Pacific Northwest.

Description

On December 7, 1988, at 11:41 A.M. local time a magnitude 6.9 earthquake shook northwestern Armenia and was followed four minutes later by a magnitude 5.8 aftershock. Swarms of aftershocks, some as large as magnitude 5.0, continued for months in the area around Spitak. The earthquakes hit an area 80 km in diameter including the towns of Leninakan, Stepanavan, Kirovakan, and Spitak (Republic of Armenia). The region is part of a broad seismic zone stretching from Turkey to the Arabian Sea near India. Here, the Arabian land mass is slowly colliding with the Eurasian plate and thrusting up the Caucasus Mountains in the north. The earthquake occurred along a fairly small thrust fault running northwest-southeast, apparently right under Spitak. During the earthquake, the Spitak section to the northeast of the fault rode up over the southwest side. Geologists have located a 1.6 meter-high, 8-km long scarp just southeast of Spitak where fault movement broke the surface. The earthquake epicenter was located in the Lesser Caucasus highlands, 80 km south of the main range of the Caucasus Mountains. Historically, this area has experienced damaging earthquakes. In 1899 and 1940, damaging earthquakes occurred within 100 km of the 1988 epicenter. These events had magnitudes of 5.3 and 6.0 respectively. In 1920, a 6.2 magnitude earthquake that killed forty people occurred north of Spitak. In 1926, an earthquake of about magnitude 5.6 occurred 20 km southwest of Leninakan and reportedly caused more than 300 deaths and extensive damage. Despite its moderate size, the deaths and damage that the December 1988 earthquake caused made it the largest earthquake disaster since the 1976 magnitude 7.8 earthquake in Tangshan, China, that killed more than 240,000 people. The Town of Spitak (population 25,000) was nearly leveled and more than half of the structures in the City of Leninakan (population 250,000) were damaged or destroyed. Damage also occurred in Stepanavan and Kirovakan and other smaller cities. Direct economic losses were put at $14.2 billion (U.S.) at the United Nations official exchange rate. Twenty-five thousand were killed and 15,000 were injured by the earthquake. In addition 517,000 people became homeless. However, 15,000 people were rescued. Most of these rescues were made within the first few hours following the disaster. Many factors contributed to the magnitude of the disaster, including freezing temperatures, time of day, soil conditions, and inadequate building construction. A large number of medical facilities were destroyed, killing eighty percent of the medical professionals. In this earthquake, both design deficiencies and flawed construction practices were blamed for the large number of building collapses and resulting deaths. Many of the modern multi-storied buildings did not survive. Soil conditions also contributed to building failures. The high death rate may in part be attributed to the way the buildings fell apart. When concrete floor panels about three feet wide collapsed into compact rubble piles, little open space was left where trapped people might survive. The proportion of survivors trapped in the rubble of multi-storied buildings was approximately 3.5 times higher for the ground floor than for higher floors. The collapse of a large number of apartments-which had many occupants on upper floors-added to the number of fatalities. While the earthquake exposed the flaws in the construction, it also exposed the good in people. International teams cooperated in rescue efforts and people around the world contributed financial aid. With undaunted determination, Armenians began to rebuild their cities and their lives.

In the future, exploration missions will benefit greatly from advanced metrology capabilities, particularly structural health monitoring systems that provide real time in situ diagnostics and evaluation of structural integrity. Safety- and mission-critical components and systems will be instrumented with embedded sensors to provide a real-time indication of health, helping to ensure that America's space exploration remains safe and cost efficient. One of the most promising technologies for accomplishing this is fiber-optic sensors. Due to their light-weight and multiplexing potential, fiber-optic sensors are highly desirable for employment in this fashion. However, most COTS devices are bench sized units and are too large and heavy to be overly attractive for space applications. To address this shortcoming, Luna Innovations proposes to develop a compact, light-weight, low-power consumption, multi-parameter distributed sensor system based on the OFDR technique. The interrogator will incorporate optical ASIC technology, highly integrated tunable VCSEL technology, and state-of-the-art integrated processing technology to dramatically reduce the size, weight, and cost and to dramatically increase the performance and robustness relative to COTS OFDR interrogator units. This interrogator will interface with fiber-optic strain, temperature, and shape sensor arrays, enabling simultaneous interrogation of a multitude of sensors, dramatically reducing the per sensor cost of instrumentation.
