    SED-ED, a workflow editor for computational biology experiments written in SED-ML (2012)
    Oxford University Press
    Details
    Publication Date: 2012-04-08
    Description: : The simulation experiment description markup language (SED-ML) is a new community data standard to encode computational biology experiments in a computer-readable XML format. Its widespread adoption will require the development of software support to work with SED-ML files. Here, we describe a software tool, SED-ED, to view, edit, validate and annotate SED-ML documents while shielding end-users from the underlying XML representation. SED-ED supports modellers who wish to create, understand and further develop a simulation description provided in SED-ML format. Availability and implementation: SED-ED is available as a standalone Java application, as an Eclipse plug-in and as an SBSI ( www.sbsi.ed.ac.uk ) plug-in, all under an MIT open-source license. Source code is at https://sed-ed-sedmleditor.googlecode.com/svn . The application itself is available from https://sourceforge.net/projects/jlibsedml/files/SED-ED/ Contact: richard.adams@ed.ac.uk

    Thermal Performance of a Heated Plate With Open-Channel Infrared Radiation Shields (1989)
    American Society of Mechanical Engineers
    Details
    Publication Date: 1989-08-01
    Description: The heat transfer associated with various radiation shield designs has been investigated. Mathematical models were used to characterize the thermal performance of a vertical heated plate, with and without a continuous radiation shield, under various environmental conditions. Predictions were compared with laboratory results taken under simulated solar radiation and wind conditions. Measurements of channel temperature and velocity distributions were made to help characterize the thermal performance. Plate temperature predictions from the model, using measured power input, ambient temperature, and channel air velocities, gave results which were within 5° C of the experimental values. The infrared energy emitted in the 8—14μ band was calculated as a function of the measured plate and/or screen temperatures for each set of experimental conditions. Double layers of incised radiation shields were found to have the lowest effective infrared energy emission. For the two screen incision sizes tested, the size of the incision did not significantly influence the temperature and velocity profiles or the amount of radiant energy emitted from the plate/screen combination.

    Measurement of orbital dynamics of the OAST-1 Solar Array using recorded video images (1985)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The OAST-1 Solar Array Experiment was flown on Shuttle mission STS-41D on August 31, 1984 for NASA's Office of Aeronautics and Space Technology. It is pointed out that this was the first flight demonstration of the operation of a large solar array which was designed for multiple deployments and retractions. The array represents also a new class of very lightweight, flexible, low-frequency structures. A program was, therefore, implemented with the aim to study the structural dynamics of the array on the basis of a photogrammetric analysis of data obtained with the existing Shuttle closed circuit television (CCTV) system. The present paper has the objective to describe the experiment and its implementation, taking into account the unique process of analyzing the video data.

    Langley Research Center Photogrammetric Measurements of Solar Array Dynamics: Preliminary Results (1985)
    In:  CASI
    Details
    Publication Date: 2014-09-18
    Description: The NASA Langley Research Center participated in the Solar Array Experiment with two primary objectives: (1) to study the structural and control dynamics of a new class of large, lightweight, low-frequency space structures, and (2) to develop technology for remote video measurement of structural motions. The shuttle orbiter's closed circuit television (CCTV) system was used to provide recorded video images of the solar array from four locations in the payload bay, two on the forward bulkhead and two on the aft bulkhead. White reflective targets were placed on the array to provide discrete points at which to track array motion. A dynamic test consisted of a quiescent period in which orbiter operations were inhibited and crew motion restricted, an excitation period, and a free decay period. The orbiter was placed in free drift while in a gravity gradient orientation and dynamics tests were timed to occur at orbital noon so that the Sun would illuminate one side of the array and Earth albedo the other. The CCTV system was turned on during the quiescent period, approximately 3 minutes prior to excitation. Video from all four CCTV cameras was recorded continuously through the excitation and free-decay periods for a total test record of 8 to 10 minutes.

    Photography and photographic-photometry of the solar aureole (1983)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: This paper describes procedures for taking solar aureole photographs with conventional small format (35- or 70-mm) cameras and films and discusses photographic-photometry techniques for obtaining accurate solar aureole radiance measurements from these photographs, the measurements being used for retrieving atmospheric aerosol characteristics. The photographic data reduction techniques discussed here include sensitometry, densitometry, off-axis illumination distribution measurement, photogrammetry and photometry relations, etc. Comparison tests show that photographic measurements of the solar aureole radiance agree well with simultaneous photoelectric measurements.

    Measured and Calculated Neutron Spectra and Dose Equivalent Rates at High Altitudes; Relevance to SST Operations and Space Research (1974)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: Results of the NASA Langley-New York University high-altitude radiation study are presented. Measurements of the absorbed dose rate and of secondary fast neutrons (1 to 10 MeV energy) during the years 1965 to 1971 are used to determine the maximum radiation exposure from galactic and solar cosmic rays of supersonic transport (SST) and subsonic jet occupants. The maximum dose equivalent rates that the SST crews might receive turn out to be 13 to 20 percent of the maximum permissible dose rate (MPD) for radiation workers (5 rem/yr). The exposure of passengers encountering an intense giant-energy solar particle event could exceed the MPD for the general population (0.5 rem/yr), but would be within these permissible limits if in such rare cases the transport descends to subsonic altitude; it is in general less than 12 percent of the MPD. By Monte Carlo calculations of the transport and buildup of nucleons in air for incident proton energies E of 0.02 to 10 GeV, the measured neutron spectra were extrapolated to lower and higher energies and for galactic cosmic rays were found to continue with a relatively high intensity to energies greater than 400 MeV, in a wide altitude range. This condition, together with the measured intensity profiles of fast neutrons, revealed that the biologically important fast and energetic neutrons penetrate deep into the atmosphere and contribute approximately 50 percent of the dose equivalant rates at SST and present subsonic jet altitudes.

    Details
    Publication Date: 2019-06-28
    Description: Small light-powered meter measures accumulated radiation in ultraviolet or other selected regions. Practical advantages are device's low cost, small size, accuracy, and adaptability to specific wave-band measurements. Medical applications include detection of skin cancer, vitamin D production, and jaundice. Dosimeter also measures sunlight for solar energy designs, agriculture and meteorology, and monitors stability of materials and environmental and occupational lighting.
