This data set contains lidar point data from a strip of Southern California coastline (including water, beach, cliffs, and top of cliffs) from Dana Point to Point La Jolla. The data set was created by combining data collected using an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 in combination with geodetic quality Global Positioning System (GPS) airborne and ground-based receivers. The Bureau of Economic Geology, the University of Texas at Austin owns and operates an ALTM 1225 system (serial number 99d118). The system is installed in a single engine Cessna 206 (tail number N4589U) owned and operated by the Texas State Aircraft Pooling Board. The lidar data set described by this document was collected at low tide on 22 May 2002 (14202) between 18:20 and 21:39 UTC (actual data collection). Conditions on that day were light clouds along the shoreline as well as offshore. 99d118 instrument settings for this flight were; laser pulse rate: 25kHz, scanner rate: 26Hz (28Hz for calibration target), scan angle: +/-20deg, beam divergence: narrow, altitude: 680-780m AGL for first half of flight and 900-950 for second half of flight, and ground speed: 83-125kts. Two GPS base stations (Scripps pier and San Onofre Power Plant) were operating during the survey. The survey included 3 shoreline passes between Dana Point and Point La Jolla as well as one offshore pass along the 20m isobath. Data represented is all points including terrain, vegetation, and structures. This data also contains returns from the water surface. No processing has been done to remove returns from terrain, vegetation, structures or water surfaces.

The Command, Control, Communications and Information (C3I) environment will be significantly different for Constellation than for Shuttle and International Space Station (ISS). Missions will operate not only in Near Earth round-trip latencies (RTLT) of seconds but also Near Mars RTLT of 10 to 40 minutes. New classes of collaboration services are required to support the spectrum of Constellation missions and infrastructure. Integrating popular collaboration tools such as Groove Virtual Office on Constellation C3I space-based components and networks will be a major innovation. This project proposes experimental use in SBIR Phases II/III of ISS flight and ground capabilities to demonstrate new collaboration services for use in the Constellation program. These new space-based and terrestrial services will greatly improve communications among all Constellation personnel over current techniques. The approach includes: 1) Integrate instant messaging, e-mail, transcription, etc. with voice and video communications; 2) Design for automation and autonomy of space-based Constellation components; 3) Evolve development collaboration services into mission collaboration services over time; 4) Promote new collaboration standards, interoperability, standardized interfaces, and modularity; 5) Adapt the collaboration architecture to the ground and space networks and frameworks. Client-server, peer-to-peer, or a hybrid architecture may be most suitable.

Notice to Data Users: The documentation for this data set was provided solely by the Principal Investigator(s) and was not further developed, thoroughly reviewed, or edited by NSIDC. Thus, support for this data set may be limited. This data set consists of Vegetation Water Content (VWC) data for two Soil Moisture Experiment 2003 (SMEX03) regional study areas, Oklahoma North and Oklahoma South. VWC was derived from the Normalized Difference Water Index (NDWI) which was obtained from Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper (ETM+) imagery. Though Landsat satellite data were acquired for multiple dates, data acquired on 10 July 2003 were selected as providing ideal conditions for the estimation of VWC. Data are provided as flat binary files and are available via FTP. Individual data values must be divided by 32 to obtain the actual vegetation water content in kg/m2. These data were collected as part of a validation study for the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E). AMSR-E is a mission instrument launched aboard NASA's Aqua Satellite on 04 May 2002. AMSR-E validation studies linked to SMEX are designed to evaluate the accuracy of AMSR-E soil moisture data. Specific validation objectives include assessing and refining soil moisture algorithm performance; verifying soil moisture estimation accuracy; investigating the effects of vegetation, surface temperature, topography, and soil texture on soil moisture accuracy; and determining the regions that are useful for AMSR-E soil moisture measurements.

Based on the success of the phase I effort, Advanced Technologies Group, Inc. proposes the development of a Cryogenic Flow Sensor (CFS) for determining mass flow of cryogens in spacecraft propellant management. Current point sensor technology is incapable of determining high pressure, high flow rate cryogenic fluid quality and mass flow rate, and has proven to be inaccurate in attempting to rapidly measure cryogen depletion. If there is an abrupt change in fluid quality, turbo-machinery can over-speed causing catastrophic failure. The CFS will provide a means to avoid these failures as well as providing fluid quality data for a wide range of flow systems. Experimental hardware was able to detect the onset of two-phase flow and the presence of debris in the flow of water. The innovation clearly shows that it can discern between entrained gas bubbles and unwanted debris. The sensor has the potential to determine size and quantity of the contaminant. In addition, a non-intrusive method for determining the Mass-Flow?Rate of the fluid propellant has been designed, and is the focus of this phase II effort.

Space Micro has developed the architecture for a radiation hardened memory subsystem that targets DDR3-and-beyond generations of DRAM. The architecture combines server platform error correction and memory buffer-on-board schemes with Space Micro proprietary techniques for radiation hardening and size, weight, and power reduction. During the NASA Phase I effort, Space Micro demonstrated two key elements of the architecture: (1) a scalable error correction coding (ECC) scheme that optimizes the robustness vs. efficiency vs. chip count tradespace, and (2) a Rad Hard By Design (RHBD) timing circuit for advanced DRAM fly-by routing. Space Micro has developed a Phase II plan for developing a server platform-like bridge chip that integrates ECC, interface logic, and timing circuitry into a high performance, low size, weight, and power (SWaP) memory subsystem suitable for next generation spacecraft computing.

One of the primary missions of the National Ocean Service (NOS) and its predecessor agencies has been to accurately survey the coast of the United States. Beginning in the late 1930's, metric aerial photographs have become the primary source material for coastal survey maps and digital cartographic feature files. Photographic surveys replaced plane table field surveys because they could be completed faster and less expensively.The vertical aerial photographs which are shot and maintained by the National Geodetic Survey (NGS), are used for a variety of geo-positioning application including shoreline delineation, mapping water depths, topographic mapping, mapping seabed characteristics, and locating features or obstructions to ensure the safety of marine and air navigation.NGS's area of photogrammetric responsibilities includes all coastal regions, including the Great Lakes and their connecting navigable waterways. This represents approximately 95,000 miles of shoreline. NGS maintains a library of all vertical aerial photographic surveys of the coast dating back to 1945. There are currently over 500,000 photographs in the library with 15,000 additional photographs being acquired each year. All photographs are available to the public for purchase.

To date there are several approaches for incorporating sensing capabilities into RFID. Active tags use batteries to power their communication circuitry, sensors, and microcontroller. Active tags benefit from relatively long wireless range and can achieve high data and sensor activity rates. However, the batteries required by active tags are disadvantageous for device cost, lifetime, weight, and volume. In contrast, passive sensor tags receive all of their operating power from external RF transmitting sources and are not limited by battery life. One attractive feature of passive sensor tags is the prospect of permanently embedding them in objects for structural monitoring. Another is their suitability for applications in which neither batteries nor wired connections are feasible, for weight, volume, cost, or other reasons. A limitation of purely passive sensor tags is the requirement of proximity to a RF transmitter. Since lower power consumption is one major trend in RF circuit design, a self-powered system by means of energy harvesting becomes very attractive. It can serve as the enabling technology for novel applications such as ambient intelligence. Using a power harvesting technique for wireless rechargeable battery smart sensor and enhanced RFID are the key elements for successfully distributing sensors across sensor networks.

Summary
Description
Bathymetry for St. Helena Sound was derived from nineteen surveys containing83,246 soundings. No surveys were omitted. The average separationbetween soundings was 49 meters. Sixteen of the nineteen surveys useddated from 1934. The remaining surveys, located in the southwest, dated from1956 and 1973. The total range of sounding data was 3.7 meters to -23.5meters at mean low water. Mean high water values between 1.5 and 2.1meters were assigned to the shoreline. Six points were found that were notconsistent with the surrounding data. These were removed prior to tinning.DEM grid values outside the shoreline (on land) were assigned nullvalues (-32676).St. Helena Sound has eleven 7.5 minute DEMs and a single one degreeDEM. The 1 degree DEMs were generated from the higher resolution 7.5minute DEMs which covered the estuary. A Digital Elevation Model(DEM) contains a series of elevations ordered from south to northwith the order of the columns from west to east. The DEM isformatted as one ASCII header record (A- record), followed by aseries of profile records (B- records) each of which include a shortB-record header followed by a series of ASCII integer elevations(typically in units of 1 centimeter) per each profile. The lastphysical record of the DEM is an accuracy record (C-record).The 7.5-minute DEM (30- by 30-m data spacing) is cast on theUniversal Transverse Mercator (UTM) projection. It provides coveragein 7.5- by 7.5-minute blocks. Each product provides the samecoverage as a standard USGS 7.5-minute quadrangle but the DEMcontains over edge data. Coverage is available for many estuaries ofthe contiguous United States but is not complete.

Reliable diagnostic tools to support system health monitoring are critical both for liquid rocket experimental ground test facilities and flight systems. Here, flow induced instabilities can generate flow anomalies such as large scale pressure fluctuations that may couple with other system components and generate deleterious structural vibrations or lead to system malfunction as was evidenced in the RS-68 engine on the Delta IV system. Identifying the source of these flow instabilities is extremely difficult since they may arise from a variety of coupled phenomena such as hydrodynamics, valve timing and scheduling, and cavitation related events in cryogenic propellant and oxidizer feedlines. The proposed Phase II program addresses this deficiency; the product of this effort will be a reliable predictive tool that can characterize flow instabilities, identify dominant frequency modes, and elucidate structural response in valve and feed systems. Phase I activities demonstrated the simulation capability for instabilities in varied flow devices (e.g. venturis, orifices) used in the E-1 test facilities at NASA SSC. The Phase II work will extend this to include fluid-structure interaction for analysis of system vibration, structural damage and gauge valve response. Extensive validation will result in a predictive diagnostic tool for liquid rocket propulsion systems.
