Description

As part of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Program, Lehigh University has established the Real-Time Multi-Directional (RTMD) earthquake simulation facility at the ATLSS Engineering Research Center. The RTMD earthquake simulation facility is a next-generation earthquake research facility for seismic performance evaluation of large-scale structural systems. This facility has advanced experimental and analytical simulation capabilities to test and validate complex and comprehensive analytical and computer numerical models, leading to advances in earthquake engineering and experimental methods. The facility features a multi-directional reaction wall, five dynamic actuators, advanced instrumentation, and a tele-participation system consisting of real-time streaming data and video. Hydraulic power for the servo-actuator system is supplied by a system consisting of five pumps and three banks of accumulators that enables strong ground motion effects to be sustained in real-time for up to 30 seconds. Real-time multi-directional seismic testing of large-scale structural components and systems at the RTMD earthquake simulation facility can be performed using either the effective force method, pseudo-dynamic testing method, or the pseudo-dynamic hybrid testing method. Distributed hybrid pseudo-dynamic testing can also be performed using the RTMD facility in conjunction with other laboratory sites.

Description

This laboratory is a unique facility for research in the areas of biomechanics, applied physiology, and industrial psychology. The 30- by 40-foot laboratory has a 17-foot-high ceiling to permit the study of a variety of work practices. The lab supports studies of postural stability, human motor and mental responses, machine safety, acute musculoskeletal injuries, and heat stress evaluations. This laboratory is equipped with three core systems, an environmental control unit (ECU), two types of motion measurement systems, and two force platforms. An electromyography (EMG) measurement system and various physical signal measurement devices are also available, and can be synchronized with the core systems. The ECU can control temperature and lighting with a high degree of precision; temperature can be controlled in a range of 35-degree F to 95-degree F, 30% to 90% humidity, and 0.1 to 100 foot candles lighting. The motion measurement systems use six cameras, which are located in each corner of the room. One system uses an infrared camera which automatically calculates body-position velocities, accelerations, and interfaces directly to software programs which then calculate joint forces. These features make the system optimal for the rapid analysis of motions when all the body markers are visible throughout the range of movement being studied. For movements in which some markers may be hidden at certain times, the second type of measurement system offers a manual digitizing capacity to recover the hidden data points. This video-based system, which is controlled by the Peak Motus software application, can objectively collect, quantify, and document motion in two- and threedimensional space. These systems are interchangeable within the high bay lab. The last major items of research equipment are two force platforms, which are used to capture data such as the amount of force distribution and direction in workers' feet during walking, as well as the amount of sway in a worker's standing posture, as a predictor of stability and fall potential. These platforms rest on a sunken concrete pad so that the plate surface is level with the floor surface. The supporting pad is isolated from the rest of the floor to reduce the effects of building vibration. Research within this laboratory will focus, or has focused, on the human factors associated with the use of fire fighters boots, tribologic data collection on the interface between shoes and shoe surfaces in healthcare settings, kinematic data collection for workers performing tasks on the platform of an aerial lift, data collection for studies of gait and joint loadings for workers who use stilts, and the forces imposed on the human body during the lifting and movement of drywall sheeting in construction tasks.

Description

Polymeric composite materials that are currently utilized in aircraft structures are susceptible to significant damage from lightning strikes. Enhanced electrical and thermal conductivity in these polymeric composites could eliminate this damage. The addition of this multifunctional capability to composites will result in lower manufacturing costs and weight reductions in future aircraft since the addition of coatings, conductive mesh, or expanded foil materials can be eliminated. A combined materials and engineering approach will be utilized to accomplish this objective by modifying a high performance composite system with a combination of conductive nano and micron size filler materials. The large difference between the two filler sizes will create a stratified composite structure that consists of the conductive micron size particles residing in the interlayer region of the composite with the nanomaterials dispersed evenly throughout the matrix and in the fiber tows. Using this approach, these composites will have the same or better balance of mechanical properties as current state-of-the-art composite systems but also have the added functionality of a conductive interlayer and network to eliminate damage from lightning strikes. The Technology Readiness Level will be between 3 and 4 after the Phase 1 program.

Description

This part of SIM 3254 presents data for faults for the geologic and geomorphic map (see sheet 10, SIM 3254) of the Offshore of Ventura map area, California. The vector data file is included in "Faults_OffshoreVentura.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreVentura/data_catalog_OffshoreVentura.html. The Offshore of Ventura map area is in the Ventura Basin, in the southern part of the Western Transverse Ranges geologic province, which is north of the California Continental Borderland (Fisher and others, 2009). This province has undergone significant north-south compression since the Miocene, and recent GPS data suggest north-south shortening of about 6 to 10 mm/yr (Larson and Webb, 1992; Donnellan and others, 1993). The active, north-verging Oak Ridge Fault and the south-verging Pitas Point-Ventura Fault are two of the structures on which this shortening occurs (for example, Sorlien and others, 2000; Fisher and others, 2005, 2009). High-resolution seismic-reflection profiles (sheet 8, SIM 3254) reveal that neither fault ruptures the surface; instead, the surface expression of each fault is a narrow, asymmetric fold that involves the uppermost Pleistocene and Holocene (less than 21 ka) sedimentary section. Both structures are inferred to be parts of long fault systems that extend for more than 100 km, representing important potential earthquake hazards (for example, Fisher and others, 2009). Shortening is also occurring on the Montalvo Fault and Anticline system along the southeast edge of the map area (part of the broader Oak Ridge Fault Zone; Yeats, 1998) and on the Rincon-Ventura Avenue Anticline (for example, Rockwell and others, 1988), which crosses the northwest edge of the map area.

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. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2010 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.

Description

<p>A key technical difference (aside from the differences in toxicity) between Hydrazine and the green propellant alternatives is the combustion temperature.  Both types of propellants are dispensed from their feed tanks through a catalyst material.  The catalyst decomposes (reacts) with each propellant and creates the high temperature exhaust gases that are used to either provide thrust (in the application of a rocket engine) or to spin the turbine which provides power to an APU or EPU.  Hydrazine decomposes at 900 deg C while the green propellants decompose at 1600 deg C.  However, the existing H-70 catalyst (Shell 405) works best with dual-bonded nitrogen mixtures.  Both ADN and HAN offer this dual-bonded feature.  Although the green propellants may burn hotter with their own proprietary catalyst material, they will burn cooler with the Shell 405 product.</p><p>Additionally, both propellants are mixed with water and the water content can be increased to further reduce combustion temperatures.  For this proposal, KSC will ship their green sensors (either for ADN or HAN) to MSFC and we in turn would instrument the EPU dedicated to that propellant.  Following completion of one month of testing the EPU instrumented with leak detection sensors, the hardware would be shipped to DFRC for a ground test inside an F-16 aircraft.  For the chosen aircraft, the existing H-70 system would be temporarily replaced with the MSFC provided green propellant EPU and the aircraft would be suspended off the ground (jacked) to simulate an engine failure and resultant use of the EPU.  The objective would be to show that the landing gear could be deployed and aero control surfaces would properly move to pilot commands.</p><p> </p><p>Alternative approaches to providing power to an APU include an external gas blowdown system, a Lithium Ion battery driven motor or a thermal battery driven motor.  All of these approaches have some drawbacks.  An external gas blowdown system may employ the use of a stored gas, most likely Helium, to drive the APU turbine.  The primary disadvantage to this system is the mass and volume required to store the compressed gas.  A similar approach that would minimize the mass and volume is to use gaseous Hydrogen tapped off a liquid propellant rocket engine.  However, APU checkouts would be problematic without the engine in operation.  An additional system would be required to provide the gas for checkout purposes.  In addition, future launch system elements may not have direct access to the liquid rocket engine and would require a disconnect for staging adding to its complexity.  Lithium Ion batteries require many cells that must be matched which drive the weight and costs.  The disadvantage of thermal batteries lies in its operation or turnaround.  For APU checkouts, an external power source is required and in the event of a launch abort or scrub, these batteries must be replaced.  These green propellants provide a high power density packaged power source that can be started multiple times with minimal effects on turnaround from issues presented.  In addition, this propellant could not only provide a propellant source for APU’s but also launch vehicle roll control.</p><p> </p>

This data set contains baseflow streamwater concentrations of pH, specific conductivity, base cations, carbon (dissolved organic carbon (DOC), particulate organic carbon (POC) and bicarbonate alkalinity) and silica for four headwater streams in the seasonally dry Amazon (Johnson et al. (2006a) and Johnson et al. (2006b). Data are provided in one comma-separated ASCII file.This hydrologic study of four headwater watersheds was conducted in an undisturbed forest near Juruena, Mato Grosso in the seasonally dry, southern Amazon. The small catchments range in size from 0.85 to 1.9 ha. Stream water samples were collected weekly during rainy seasons and biweekly during the dry seasons. Baseflow stream water concentrations of base cations, silica, electrical conductivity, DOC, and alkalinity varied inversely with discharge. While there was variation among the watersheds, the concentration-discharge patterns were consistent for each of the four watersheds. Baseflow discharge data are not included in this data set and will be archived separately.

The purpose of this study is to develop a tool to help decision makers incorporate the wide range of stakeholder preferences for managing bison and elk at the National Elk Refuge and Grand Teton National Park and to show stakeholders how their preferences were included in the decision making process. We integrated concepts from decision analysis, political and institutional analysis, and public choice economics into a single, comprehensive approach called Disparate Stakeholder Management DSM. The objective of developing the DSM approach is to help decision makers better describe, measure, communicate, and resolve management issues with disparate stakeholders. We demonstrate the DSM approach on elk and bison management and show how knowing about stakeholder preferences can increase satisfaction overall for stakeholders, even when they hold very different view.

Description

SiWave proposes to develop a compact, low-cost MEMS-based pressure sensor for very high temperatures and low pressures in hypersonic wind tunnels. Most currently available pressure sensors use a micromachined diaphragm whose deflection is dependent on pressure. The deflection is typically measured by techniques that are not suited for high temperature (>~200?F) operation, or that are insensitive to small (<~0.1 psi) pressure changes. As a result, no commercial sensors cover 0-5 PSI at temperatures above 200?F, despite the fact that this regime is important for NASA?s hypersonic wind tunnel testing programs, as well as for hypersonic flight avionics. SiWave?s proposed pressure sensor is a novel implementation of squeeze film resonant sensor approach, with a sophisticated multi-element resonator designed for very high Q and temperature stability, made from silicon carbide. The device is controlled by distant external electronics. These innovative features result in a sensor with high accuracy (0.005 PSI) over an unprecedented temperature range (up to 650?F), and the potential to be manufactured in dense arrays.

Description

This dataset contains an ESRI Grid representing the rugosity of the bathymetry of the north shore of St. Croix, US Virgin Islands and south west shore (La Parguera) of Puerto Rico, based on a 10 m bathymetric grid. Rugosity is defined as the ratio of surface area to planar area and is used as a measure of benthic terrain complexity or "roughness". Rugosity values near 1 represent flat, smooth terrain, while higher values reflect increasing rugosity or terrain roughness. For rugosity grid interpretation, is recommended that the grid be reclassified according to standard deviation divisions.NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 3/21/06 to 4/2/06. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) and processed by a NOAA contractor using CARIS HIPS v6.0 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.1 as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate an ESRI Grid of bathymetry. The Benthic Terrain Modeller (BTM) tool, a collection of ArcGIS terrain visualization tools developed by the Oregon State University (OSU) Department of Geosciences and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, was used to calculate the rugosity of that bathymetric grid. More information on the specific algorithms used can be found in the BTM's documentation.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Since October 1, 1983, most hospitals have been paid under the hospital inpatient prospective payment system (PPS). However, certain types of specialty hospitals and units were excluded from PPS because the PPS diagnosis related groups do not accurately account for the resource costs for the types of patients treated in those facilities. Facilities originally excluded from PPS included rehabilitation, psychiatric, childrens, cancer, and long term care hospitals, rehabilitation and psychiatric hospital distinct part units, and hospitals located outside the 50 states and Puerto Rico.
