  • pl science a Scientific software Product line
    International Conference on Conceptual Structures, 2013
    Co-Authors: Gabriella Castro Barbosa Costa, Regina Braga, Jose Maria N David, Fernanda Campos, Wagner Arbex
    Abstract:

    Abstract A way to improve reusability and maintainability of a family of software Products is through the use of Software Product Line (SPL) approach. Software families, also named SPLs, are a set of software intensive systems sharing a common set of features which are managed to satisfy specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. This paper presents the PL-Science approach that considers the context of SPL and aims to assist scientists to define a Scientific experiment, specifying a workflow that encompasses Scientific applications of a given experiment. Using SPL concepts, scientists can reuse models that specify the Scientific Product line, and carefully can make decisions according to their needs. In the context of this paper, Scientific Software Product Lines (SSPL) differs from the Software Product Lines (SPL) due to the fact that SSPL uses an abstract Scientific workflow model. This workflow is defined according to a Scientific domain and, using this abstract workflow model, the Products (Scientific applications/algorithms) will be instantiated. This paper also focuses on the use of ontologies to facilitate the process of applying Software Product Line (SPL) to Scientific domains. Through the use of ontology as a domain model, we can provide additional information as well as add more semantics in the context of Scientific Software Product Lines (SSPL).

  • Intercomparison of ozone profile measurements from ASUR, SCIAMACHY, MIPAS, OSIRIS, and SMR
    Journal of Geophysical Research: Atmospheres, 2007
    Co-Authors: J. Kuttippurath, H. Bremer, J. Burrows, A. Kleinböhl, H. Küllmann, K. Kunzi, J. Notholt, M. Sinnhuber, C. Von Savigny, N. Lautié
    Abstract:

    The airborne submillimeter radiometer (ASUR) was deployed onboard the Falcon research aircraft during the scanning imaging absorption spectrometer for atmospheric cartography (SCIAMACHY) validation and utilization experiment (SCIAVALUE) and the European polar stratospheric cloud and lee wave experiment (EuPLEx) campaigns. A large number of ozone profile measurements were performed over a latitude band spanning from 5°S to 80°N in September 2002 and February/March 2003 during the SCIAVALUE and around the northern polar latitudes in January/February 2003 during the EuPLEx. Both missions amassed an ample microwave ozone profile data set that is used to make quantitative comparisons with satellite measurements in order to assess the quality of the satellite retrievals. In this paper, the ASUR ozone profile measurements are compared with measurements from SCIAMACHY and Michelson interferometer for passive atmospheric sounding (MIPAS) on Environmental Satellite and optical spectrograph and infrared imager system (OSIRIS) and submillimeter radiometer (SMR) on the Odin satellite. The cross comparisons with the criterion that the ASUR measurements are performed within ±1000 km and ±6 hrs of the satellite observations show a good agreement with all the four satellite sensors. The differences in data values are the following: −4 to +8% for ASUR-SCIAMACHY (operational Product, v2.1), within ±15% for ASUR-SCIAMACHY (Scientific Product, v1.62), up to +6% for ASUR-MIPAS (operational Product v4.61) and ASUR-MIPAS (Scientific Product v1-O3-1), up to 17% for ASUR-OSIRIS (v012), and −6 to 17% for ASUR-SMR (v222) between the 20- and 40-km altitude range depending on latitude. Thus, the intercomparisons provide important quantitative information about the quality of the satellite ozone profiles, which has to be considered when using the data for Scientific analyses.

  • Mutualism (carpooling) of ecologists and taxonomists
    Biodiversity and Conservation, 2016
    Co-Authors: Andrew L. Sheldon
    Abstract:

    Ecologists and taxonomists have a common stake in the biodiversity enterprise but approach problems differently. Ecologists use structured designs to obtain multispecies samples and supporting information which they transform to data for analysis. Taxonomists obtain collections by less formal search, are specimen- rather than data-focused, target rare and undescribed species, and organize specimens and data by taxon with less attention to associated species and environmental data. Ecologists undervalue their contributions to taxonomic and distributional research. Taxonomists pass by the multispecies and negative occurrence data in collections. Complementarity of taxonomic and ecological approaches guarantees a stronger Scientific Product but effective collaboration requires continuing reciprocal involvement by both parties.
