  • An Action Research for Improving the Sustainability Assessment Framework Instruments 

    Condori-Fernandez, Nelly; Lago, Patricia; Rodríguez Luaces, Miguel; Places, Ángeles S. (M D P I AG, 2020-02-24)
    [Abstract] In the last years, software engineering researchers have defined sustainability as a quality requirement of software, but not enough effort has been devoted to develop new methods/techniques to support the ...
  • Efficient processing of raster and vector data 

    Silva-Coira, Fernando; Paramá, José R.; Ladra, Susana; López, Juan R.; Gutiérrez, Gilberto (Public Library of Science, 2020-01-10)
    [Abstract] In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vector dataset. More concretely, we ...
  • Energy Consumption in Compact Integer Vectors: A Study Case 

    Fuentes Sepúlveda, José; Ladra, Susana (Institute of Electrical and Electronics Engineers, 2019-10-25)
    [Abstract] In the field of algorithms and data structures analysis and design, most of the researchers focus only on the space/time trade-off, and little attention has been paid to energy consumption. Moreover, most of the ...
  • Improved Compressed String Dictionaries 

    Brisaboa, Nieves R.; Cerdeira Pena, Ana Belén; De Bernardo Roca, Guillermo; Navarro, Gonzalo (ACM, 2019-11-03)
    [Abstract] We introduce a new family of compressed data structures to efficiently store and query large string dictionaries in main memory. Our main technique is a combination of hierarchical Front-coding with ideas from ...
  • Design of Mutation Operators for Testing Geographic Information Systems 

    Alvarado, Suilen H. (M D P I AG, 2019-08-06)
    [Abstract] In this article, we propose the definition of specific mutation operators for testing Geographic Information Systems. We describe the process for applying the operators and generating mutants, and present a case ...
