  • Mungara, Ratheesh K.; Morales-Jiménez, David; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Capitalizing on the analytical potency of stochastic geometry and on some new ideas to model intercell interference, this paper presents analytical expressions that enable quantifying the spectral efficiency of IA ...
  • Martín Borregon, David; Aiello, Luca Maria; Grabowicz, Przemyslaw; Jaimes, Alejandro; Baeza-Yates, Ricardo (SpringerOpen, 2014)
    Social groups play a crucial role in online social media because they form the basis for user participation and engagement. Although widely studied in their static and evolutionary aspects, no much attention has been devoted ...
  • Amiri Nezhad, Maryam; Guerrero Zapata, Manel; Bellalta, Boris; Cerdà Alabern, Llorenç (SpringerOpen, 2014)
    In the context of wireless network simulation, many simulators are capable of evaluating the performance of single-channel network protocols, but they need many modifications to be able to simulate multi-radio multi-channel ...
  • Canadas Quesada, Francisco Jesus; Vera Candeas, Pedro; Ruiz Reyes, Nicolas; Carabias Orti, Julio; Cabanas Molero, Pablo (SpringerOpen, 2014)
    In this paper, unsupervised learning is used to separate percussive and harmonic sounds from monaural non-vocal polyphonic signals. Our algorithm is based on a modified non-negative matrix factorization (NMF) procedure ...
  • Carabias Orti, Julio J; Cobos, Máximo; Vera Candeas, Pedro; Rodríguez Serrano, Francisco J (SpringerOpen, 2013)
    Close-microphone techniques are extensively employed in many live music recordings, allowing for interference rejection and reducing the amount of reverberation in the resulting instrument tracks. However, despite the use ...
