• Target wake time: scheduled access in IEEE 802.11ax WLANs

  Nurchis, Maddalena; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2019)

  The increasing interest in ubiquitous networking, and the tremendous popularity gained by IEEE 802.11 WLANs in recent years, is leading to very dense deployments where high levels of channel contention may prevent meeting ...
• Measuring the evolution of contemporary western popular music

  Serrà, Joan; Corral, Álvaro; Boguñá, Marián; Haro Berois, Martín; Arcos, Josep Lluis (Nature Research, 2012)

  Popular music is a key cultural expression that has captured listeners' attention for ages. Many of the structural regularities underlying musical discourse are yet to be discovered and, accordingly, their historical ...
• Measuring ensemble interdependence in a string quartet through analysis of multidimensional performance data

  Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Pérez Carrillo, Alfonso Antonio, 1977-; Maestre Gómez, Esteban (Frontiers, 2014)

  In a musical ensemble such as a string quartet, the musicians interact and influence each other's actions in several aspects of the performance simultaneously in order to achieve a common aesthetic goal. In this article, ...
• Enriched multimodal representations of music performances: online access and visualization

  Maestre Gómez, Esteban; Papiotis, Panagiotis, 1985-; Marchini, Marco, 1984-; Llimona, Joaquim; Mayor Soto, Oscar; Pérez Carrillo, Alfonso Antonio, 1977-; Wanderley, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)

  The authors provide a first-person outlook on the technical challenges involved in the recording, analysis, archiving, and cloud-based interchange of multimodal string quartet performance data as part of a collaborative ...
• Collaborative spatial reuse in wireless networks via selfish multi-armed bandits

  Wilhelmi Roca, Francesc; Cano, Cristina; Neu, Gergely; Bellalta, Boris; Jonsson, Anders, 1973-; Barrachina Muñoz, Sergio (Elsevier, 2019)

  Next-generation wireless deployments are characterized by being dense and uncoordinated, which often leads to inefficient use of resources and poor performance. To solve this, we envision the utilization of completely ...
• To overlap or not to overlap: Enabling channel bonding in high-density WLANs

  Barrachina Muñoz, Sergio; Wilhelmi Roca, Francesc; Bellalta, Boris (Elsevier, 2019)

  Wireless local area networks (WLANs) are the most popular kind of wireless Internet connection because of their simplicity of deployment and operation. As a result, the number of devices accessing the Internet through WLANs ...
• Optimizing resource allocation for virtualized network functions in a cloud center using genetic algorithms

  Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2017)

  With the introduction of network function virtualization technology, migrating entire enterprise data centers into the cloud has become a possibility. However, for a cloud service provider (CSP) to offer such services, ...
• A Machine learning approach to ornamentation modeling and synthesis in jazz guitar

  Ramírez, Rafael; Giraldo, Sergio (Taylor & Francis, 2016)

  We present a machine learning approach to automatically generate expressive (ornamented) jazz performances from un-expressive music scores. Features extracted from the scores and the corresponding audio recordings performed ...
• Spectral analysis of quadrature rules and fourier truncation-based methods applied to shading integrals

  Marques, Ricardo; Bouville, Christian; Bouatouch, Kadi (Institute of Electrical and Electronics Engineers (IEEE), 2019)

• Different ERP profiles for learning rules over consonants and vowels

  Monte Ordoño, Julia, 1989-; Toro Soto, Juan Manuel, 1976- (Elsevier, 2017)
