  • AlSkaif, Tarek; Luna, Adriana C.; Guerrero Zapata, Manel; Guerrero, Josep M.; Bellalta, Boris (Elsevier, 2017)
    Due to the decreasing revenues from the surplus renewable energy injected into the grid, mechanisms promoting self-consumption of this energy are becoming increasingly important. Demand response (DR) and local storage are ...
  • Barrachina Muñoz, Sergio; Bellalta, Boris; Adame, Toni; Bel, Albert (Elsevier, 2017)
    Low-Power Wide Area Networks (LPWANs) have arisen as a promising communication technology for supporting Internet of Things (IoT) services due to their low power operation, wide coverage range, low cost and scalability. ...
  • Faridi, Azadeh; Bellalta, Boris; Checco, Alessandro (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Dynamic Channel Bonding (DCB) allows for the dynamic selection and use of multiple contiguous basic channels in Wireless Local Area Networks (WLANs). A WLAN operating under DCB can enjoy a larger bandwidth, when available, ...
  • Sanabria Russo, Luis; Barceló, Jaume; Bellalta, Boris; Gringoli, Francesco (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Collisions are a main cause of throughput degradation in wireless local area networks. The current contention mechanism used in the IEEE 802.11 networks is called carrier sense multiple access with collision avoidance ...
  • Vázquez, Toni Adame; Barrachina Muñoz, Sergio; Bellalta, Boris; Bel, Albert (MDPI, 2018)
    The emergence of low-power wide area networks (LPWANs) as a new agent in the Internet of Things (IoT) will result in the incorporation into the digital world of low-automated processes from a wide variety of sectors. The ...
  • Lyamin, Nikita; Vinel, Alexey; Jonsson, Magnus; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Cooperative awareness on the road is intended to support the road users by providing knowledge about the surroundings and relies on the information exchange enabled by vehicular communications. To achieve this goal the ...
  • Nettleton, David F.; Orriols Puig, Albert; Fornells, Albert (Springer, 2010)
    Machine learning techniques often have to deal with noisy data, which may affect the accuracy of the resulting data models. Therefore, effectively dealing with noise is a key aspect in supervised learning to obtain reliable ...
  • Fabri, Marcelus; Ramalhinho, Helena; de Souza, Mauricio C.; Ravetti, Martin G. (Hindawi, 2019)
    This work aims to present a methodology to support a company in the automotive business on scheduling the jobs on its final processes. These processes are: (i) checking the final product and (ii) loading the dispatch trucks. ...
  • Liu, Fan; García Rodriguez, Adrián; Masouros, Christos; Geraci, Giovanni (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    In this paper, we focus on the coexistence between a MIMO radar and cellular base stations. We study the interfering channel estimation, where the radar is operated in the “search and track” mode, and the BS receives the ...
  • Fang, Dong; Huang, Yu Chih; Geraci, Giovanni; Ding, Zhiguo; Claussen, Holger (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    The fifth-generation (5G) air interface, namely, dynamic multiple access (MA) based on multiuser superposition transmission (MUST) and orthogonal MA (OMA), may require a complicated scheduling and heavy signaling overhead. ...
  • Al-Nahari, Azzam; Geraci, Giovanni; Al-Jamali, Mukarram; Hossam Ahmed, Mohamed; Yang, Nan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    In this paper, we consider multiple-input single-output multi-eavesdropper cognitive radio networks (MISOME-CRNs), where a secondary user (SU) aims to transmit confidential information to a legitimate SU receiver in the ...
  • Hernandez, Mireia; Fairhall, Scott L.; Lenci, Alessandro; Baronai, Marco; Caramazza, Alfonso (MIT Press, 2014)
    Verbs and nouns are fundamental units of language, but their neural instantiation remains poorly understood. Neuro- psychological research has shown that nouns and verbs can be damaged independently of each other, and ...
  • Bernardino, Gabriel; Sanz de la Garza, Maria; Domenech Ximenos, Blanca; Prat Gonzàlez, Susanna; Perea, Rosario J.; Blanco, Isabel; Burgos, Felip; Sepúlveda Martínez, Álvaro; Rodríguez López, Mérida; Crispi, Fàtima; González Ballester, Miguel Ángel, 1973-; De Craene, Mathieu; Sitges, Marta; Bijnens, Bart (Springer, 2020)
    Aims: Endurance athletes develop cardiac remodeling to cope with increased cardiac output during exercise. This remodeling is both anatomical and functional and shows large interindividual variability. In this study, we ...
  • Duñabeitia, Jon Andoni; Costa, Albert, 1970- (Springer, 2015)
    This study explores the interaction between deceptive language and second language processing. One hundred participants were asked to produce veridical and false statements in either their first or second language. Pupil ...
  • Butti, Silvia; Stanislav Zivný (SIAM (Society for Industrial and Applied Mathematics), 2020)
    A cut ε-sparsifier of a weighted graph G is a re-weighted subgraph of G of (quasi)linear size that preserves the size of all cuts up to a multiplicative factor of ε. Since their intro- duction by Bencz´ur and Karger ...
  • Bonfante, Andrea; Galati Giordano, Lorenzo; López Pérez, David; García Rodríguez, Adrián; Geraci, Giovanni; Baracca, Paolo; Butt, Majid; Marchetti, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    In this paper, we focus on one of the key technologies for the fifth-generation wireless communication networks, massive multiple-input-multiple-output (mMIMO), by investigating two of its most relevant architectures: ...
  • Geraci, Giovanni; García Rodríguez, Adrián; Galati Giordano, Lorenzo; López Pérez, David; Björnson, Emil (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    The purpose of this article is to bestow the reader with a timely study of UAV cellular communications, bridging the gap between the 3GPP standardization status quo and the more forward-looking research. Special emphasis ...
  • Goldrick, Matthew; Runnqvist, Elin; Costa, Albert, 1970- (SAGE Publications, 2014)
    It is well known that multilingual speakers’ nonnative productions are accented. Do these deviations from monolingual productions simply reflect the mislearning of nonnative sound categories, or can difficulties in processing ...
