    Article
    Open Access
    Background: Endobronchial ultrasonography (EBUS) has been applied as a routine procedure for the diagnostic of hiliar and mediastinal nodes. The authors assessed the relationship between the echographic appearance of ...
  • Generation of multiple hypothesis in connected phonetic-unit recognition by a modified one-stage dynamic programming algorithm 

    Mariño Acebal, José Bernardo; Monte Moreno, Enrique (1989)
    Conference report
    Open Access
    One of the most popular algorithms for connected word (or subword phonetic unit) recognition is the one-stage dynamic programming algorithm. In its available formulation, this algorithm is not designed to provide multiple ...
  • Global prediction of the vertical total electron content of the ionosphere based on GPS data 

    García Rigo, Alberto; Monte Moreno, Enrique; Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Aragón Ángel, María Ángeles; Salazar Hernández, Dagoberto José (2011-12-29)
    Article
    Open Access
    Although vertical total electron content (VTEC) forecasting is still an open subject of research, the use of predictions of the ionospheric state at a scale of several days is an area of increased interest. A global VTEC ...
  • GPS as a solar observational instrument: real-time estimation of EUV photons flux rate during strong, medium, and weak solar flares 

    Singh, Talwinder; Hernández Pajares, Manuel; Monte Moreno, Enrique; García Rigo, Alberto; Olivares Pulido, Germán (2015-12-15)
    Article
    Open Access
    In this manuscript, the authors show how the Global Navigation Satellite Systems, GNSS (exemplified in the Global Positioning System, GPS), can be efficiently used for a very different purpose from that for which it was ...

    Formiga Fanals, Lluís; Hernández Huerta, Adolfo; Mariño Acebal, José Bernardo; Monte Moreno, Enrique (2012)
    Conference report
    Open Access
    This paper presents a detailed study of a method for morphology generalization and generation to address out-of-domain translations in English-to-Spanish phrase-based MT. The paper studies whether the morphological richness ...
  • Internal report. Numerical methods for medium scale traveling ionospheric disturbances signal pre-processing 

    Yang, Heng; Monte Moreno, Enrique; Hernández Pajares, Manuel (2015-01-15)
    External research report
