Description

Makel Engineering and Cornell University propose to develop a galley architecture taking into account the design constraints of the space habitat, such as reduced pressure and gravity, minimize size, mass, power and crew time, while producing food with high nutritional value and enough variety, acceptable taste and texture qualities for long term crew consumption. The current design of the space habitat will have a reduced atmospheric pressure of 8 psia which is equivalent to a 16,000 foot mountain top, with oxygen enrichment to prevent hypoxia effects on the crew. The combination of reduced pressure and gravity will affect the heat and mass transfer during food processing and food preparation of the food. Whether the food system is based chiefly on bulk packaged ingredients or crops grown on site, it must minimize mass, volume, power and waste, make effective use of the limited resource of crew time, produce nutritious, highly acceptable and varied food, and integrate into the closed habitat's atmospheric control system by containing and controlling airborne particulates, water vapor and odors generated during food preparation.

Description

During our Phase I STTR effort, Balcones Technologies, LLC and The University of Texas Center for Electromechanics (CEM) successfully achieved all Phase I objectives and developed a concept design for an active Vibration Isolation System (VIS) that fully meets all requirements defined or implied in STTR 2007-1 Subtopic T6.02. Now the Balcones Technologies - CEM team proposes to develop, test, and deliver a prototype version of our active VIS. Furthermore, the delivered prototype system, coupled with our proposed Phase II commercialization activities, will be substantially advanced from a proof-of-principle system and will embody the critical aspects of pre-production systems, ready to quickly transition to the NASA qualification process and finished product. Our Phase I effort yielded a high performance, cost effective, highly reliable, actively controlled Vibration Isolation System (VIS) for ground support electronics racks or groups of racks on the Mobile Launch Platform (MLP). Some features are listed below. ? does not rely on predictable vibration input ? applies across broad range of ground support electronics or other sensitive systems ? does not depend on detailed knowledge or testing of the components being protected ? is compatible with operation from a self-contained power supply if desired by NASA ? offers up to 18x reduction in payload peak accelerations compared to passive approaches and up to 5x reduction compared to semi-active approaches ? can be configured to isolate electronics racks individually, in small groups, or via an isolation system for an entire floor ? is modular in both hardware and software, exploiting COTS and previously developed CEM technology to facilitate rapid development and commercialization ? exploits approximately $24M of highly successful active suspension R&D at CEM for military vehicles for the controls, architecture, and actuator development technology.

Description

The 2014 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. Regions are four groupings of States (Northeast, South, Midwest, and West) established by the Census Bureau in 1942 for the presentation of census data.

Description

This plan is intended to serve as a step by step guide to emergency oil spill response in the event that such a spill threatens refuge lands and wildlife. Because it may take several hours before professional oil spill responders and cleanup crews arrive, the emergency efforts of refuge personnel may play a key role in minimizing impacts to refuge lands and wildlife resources. The primary goal in this emergency response is to minimize the impacts on the trust resources of the U.S. Fish and Wildlife Service Service. Appendix A lists the priorities for Service response, as outlined in the Services Response Plan for Discharges of Oil and Releases of Hazardous Substances Service Contingency Plan SCP. For specifics regarding legal authorities and responsibilities, refer to the Service Contingency Plan. This plan pertains to spills of petroleum products only. Because of the threat to human health involved in responding to hazardous substances spills, evacuation may be the appropriate response. There are few Service personnel who are trained for hazardous spill response. The Service policy states that Service personnel will not enter hazardous waste sites without specific Regional clearance. Additionally, the likelihood of a petroleum spill in the vicinity of Laguna Atascosa is greater than that of a hazardous substance spill, since most barges carrying hazardous waste are doublehulled versus the singlehulled barges used for petroleum products. Following is a numbered, step by step response sequence that should be followed in the event an oil spill is discovered or reported to the refuge. The three most likely spill scenarios are covered in the response sequence. These three scenarios Appendix B, Figure B1, are: A A pipeline rupture at the Upper Cayo Atascosa crossing at FM 106, B A barge collision or spill in the Gulf Intracoastal Waterway GIWW C A barge collision or spill in the Harlingen Ship Channel.

There are two methods for a hospital to qualify for the Medicare DSH adjustment. The primary method is for a hospital to qualify based on a statutory formula that results in the DSH patient percentage. The DSH patient percentage is equal to the sum of the percentage of Medicare inpatient days attributable to patients eligible for both Medicare Part A and Supplemental Security Income (SSI), and the percentage of total inpatient days attributable to patients eligible for Medicaid by not Medicare Part A.

Description

Digital orthographic imagery datasets contain georeferenced images of the Earth's surface, collected by a sensor in which object displacement has been removed for sensor distortions and orientation, and terrain relief. Digital orthoimages have the geometric characteristics of a map, and image qualities of a photograph. (Source: Circular A-16, p. 16) These files contain Digital Orthophoto files for the State of Virginia developed from imagery acquired in spring 2006 and 2007. In the spring of 2006, the Commonwealth of Virginia, through the VGIN of the VITA contracted with the Sanborn Map Company to provide aerial data acquisition, ground control, aerotriangulation and development of statewide DTM and digital orthophotography. Approximately 15% of the State was acquired in the year 2006 and the balance in 2007. All data acquired in 2006 is jurisdiction based. The data acquired in 2007 includes overlap along the boundaries of jurisdictions captured in the previous year 2006. This ensures each jurisdiction has full coverage from either Year 2006 or 2007 without 'mixing' imagery vintage along the edge of a jurisdiction. The project encompasses the entire land area of the Commonwealth of Virginia. The State boundary is buffered by 1000'. Coastal areas of the State bordering the Atlantic Ocean or the Chesapeake Bay are buffered by 1000' or the extent of man-made features extending from shore. The entire State was intially designed to support 1"=200' (1:2400) scale mapping. Jurisdictions throughout the State were provided an option to upgrade to a 1"=100' (1:1200) map scale. All data development processes for the DTM conform to the ASPRS Draft Aerial Photography Standards (1995) and Model Virginia Map Accuracy Standards (1992), which generally follow the ASPRS Accuracy Standard for Large-Scale Mapping (1990) for relevant mapping scales. The DTM supports the creation of 6-inch or 1-foot map orthoimagery at the relevant scales.

Description

In 2002 and 2003, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), conducted three exploration cruises (USGS Cruise 02051, NOAA RB0208, September 24 to 30, 2002; USGS Cruise 03008, NOAA RB0303, February 18 to March 7, 2003 and USGS Cruise 03032, NOAA RB0305, August 28 to September 4, 2003). These cruises mapped for the first time the morphology of this entire tectonic plate boundary stretching from the Dominican Republic in the west to the Lesser Antilles in the east, a distance of approximately 700 kilometers (430 miles). Observations from these three exploration cruises, coupled with computer modeling and published Global Positioning System (GPS) results and earthquake focal mechanisms have provided new information that is changing the evaluation of the seismic and tsunami hazard from this plate boundary. The observations collected during these cruises also contributed to the basic understanding of the mechanisms that govern plate tectonics, in this case, the creation of the island of Puerto Rico and the deep trench north of it. Results of the sea floor mapping have been an important component of the study of tsunami and earthquake hazards to the northeastern Caribbean and the U.S. Atlantic coast off the United States. For additional information on the cruises see: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2002-051-FA http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2002-051-FA http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2002-051-FA

Description

Impact of Continued Biased Disenrollment from the Medicare Advantage Program to Fee-for-Service As reported in Impact of Continued Biased Disenrollment from the Medicare Advantage Program to Fee-for-Service, published in Volume 2, Issue 4, of the Medicare and Medicaid Research Review, disenrollment from the Medicare Advantage (MA) program to fee-for-service (FFS) continues to occur disproportionately among high-cost beneficiaries. Disenrollees incurred 1,021 dollars per month in Medicare payments following disenrollment to FFS in 2007, which was 28 percent higher than predicted based on risk scores used to set MA payment rates. Differences between actual and predicted payments were smaller for disenrollees of Preferred Provider Organizations (PPOs) and Private Fee-for-Service (PFFS) plans than for Health Maintenance Organizations (HMOs), indicating less biased disenrollment from PPOs and PFFS plans. Analysis of 10 individual MA plans revealed considerable variation in the degree of biased disenrollment. These findings raise concerns about care experiences among sicker enrollees and increased costs to Medicare.

Description

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The TIGER/Line shapefiles include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located. The boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs is that they must contain some housing and population. The boundaries of most incorporated places in this shapefile are as of January 1, 2013, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). Limited updates that occurred after January 1, 2013, such as newly incorporated places, are also included. The boundaries of all CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census.

Description

Many of NASA's exploration scenarios include important roles for autonomous or partially autonomous robots. It is desirable for them to utilize human tools when possible, rather than needing to build custom tools for each robot. Control of robotic manipulators for tool usage generally requires a very precise Cartesian-space trajectory of the tool tip (e.g., moving a marker along the surface of a whiteboard or rotating a screwdriver about an axis). Well-known techniques exist for manipulator control in Cartesian space, most of which necessitate solving a series of Inverse Kinematics (IK) problems. Closed-form IK solvers work well for 7-degree-of-freedom (DOF) arms with rigid tool attachments, but cannot handle non-rigid tools that slip in the robot's hands. Numerical IK approaches are more generic and can handle non-rigid links to tools, but can be slow to converge. More importantly, if any joints fail or become limited in their range of motion, the robot arm essentially becomes 6-DOF or lower. IK solvers often fail in these lower DOF spaces because the configuration space becomes non-continuous and full of "holes". As a result, a 7-DOF robotic arm in space might be rendered largely useless if a single joint fails or even loses mobility until it can be serviced. TRACLabs proposes to investigate an alternative approach to traditional Cartesian control approaches, which rely on complex IK solvers that go from Cartesian space backwards to joint space. We propose to leverage cheap memory and modern processing speeds to instead perform simple computations that go from joint space forwards to Cartesian space. Such techniques should overcome common changes to a manipulation chain caused by tool slippage or the grasping of a new tool and to overcome uncommon changes to a chain caused by joint failures, reduced joint mobility, changes in joint geometry or range of motion, or added joints.

Description

Projections of the onset of annual coral bleaching conditions in the Caribbean under Representative Concentration Pathway (RCP) 8.5 are produced using an ensemble of 33 Coupled Model Intercomparison Project phase-5 models via dynamical downscaling. A high-resolution (~11 km) regional ocean model (MOM4.1) is used for the dynamical downscaling. From the downscaled Sea Surface Temperature (SST) projections, an ensemble was created by replacing the mean of the 2006-2011 modeled temperature with the mean of the Pathfinder v5.0 climatology. An ensemble was made by removing the quadratic trend and annual cycle of the mean-corrected MOM4.1 all remaining monthly anomalies were randomized 33 times and the annual cycle was added back. Degree Heating Weeks (DHW) are calculated. Full methods are described in the peer reviewed article: van Hooidonk, R., Maynard, J. A., Liu, Y., & Lee, S.-K. (2015).

Description

This data set contains the Submerged Lands Act (SLA) boundary (also known as State Seaward Boundary (SSB), or Fed State Boundary) in ESRI shapefile format for the BOEM Alaska Region. The SLA boundary defines the seaward limit of a state's submerged lands and the landward boundary of federally managed OCS lands. In the BOEM Alaska Region it is projected 3 nautical miles offshore from the baseline. Further information on the SLA and development of this line from baseline points can be found in OCS Report MMS 99-0006: Boundary Development on the Outer Continental Shelf http://www.boem.gov/BOEM-Newsroom/Library/Publications/1999/99-0006-pdf.aspx. Due to slight differences in process and purpose, NOAA's 3 nautical mile line depicted on its charts may differ in some areas from the SLA boundary depicted on BOEM maps and OPDs and should not be confused with the SLA boundary. Therefore this boundary is the only boundary that should be used to depict state/federal seperation of jurisdiction for submerged lands. Because GIS projection and topology functions can change or generalize coordinates, these GIS files are considered to be approximate and are NOT an OFFICIAL record for the exact SLA boundary. The Official Protraction Diagrams (OPDs) and Supplemental Official OCS Block Diagrams (SOBDs) serve as the legal definition for offshore boundary coordinates and area descriptions.

The Integrated Science Data Management (ISDM) office processes oceanographic profiles reported for the world oceans in near real-time from the Global Telecommunications System (GTS) for the Global Temperature and Salinity Profile Program (GTSPP). These data also support the activities of the Ship of Opportunity Programme Implementation Panel (SOOPIP) and the WOCE Upper Ocean Thermal Program WOCE UOT). The ISDM sends a copy of these data to the US NODC three times each week.
