  • Nikbakht, Rasoul; Jonsson, Anders, 1973-; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This paper applies feedforward neural networks to the problem of centralized power allocation in the downlink of cell-free wireless systems with conjugate beamforming. The formulation relies only on large-scale channel ...
  • AbuRa’ed, Ahmed; Saggion, Horacio; Shvets, Alexander; Bravo Serrano, Àlex, 1984- (Springer, 2020)
    Related work sections or literature reviews are an essential part of every scientific article being crucial for paper reviewing and assessment. However, writing a good related work section is an activity which requires ...
  • Cano Bastidas, Cristina; Bellalta, Boris; Sfairopoulou, Anna; Oliver Riera, Miquel; Barceló Vicens, Jaume (Springer, 2011)
    LWT-MAC is a new Low Power Listening MAC protocol for WSNs designed to rapidly react to instantaneous increases of the network load. It takes advantage of overhearing by waking up all nodes at the end of a transmission to ...
  • Amiri Nezhad, Maryam; Cerdà Alabern, Llorenç; Bellalta, Boris; Guerrero Zapata, Manel (Inderscience Enterprises Ltd, 2013)
    Channel assignment (CA) has been extensively researched for multi-radio wireless mesh networks (WMNs), but it is still very challenging when it comes to its implementation. In this paper we propose a semi-dynamic and ...
  • AlSkaif, Tarek; Guerrero Zapata, Manel; AlSkaif, Tarek; Bellalta, Boris; Nilsson, Anders (Springer, 2016)
    In microgrids, the integration of distributed energy resources (DERs) in the residential sector can improve power reliability, and potentially reduce power demands and carbon emissions. Improving the utilization of renewable ...
  • Tovstogan, Philip; Serra, Xavier; Bogdanov, Dmitry (ICML, 2020)
    We present an online graphical web interface for the exploration and evaluation of embedding and tag spaces of music auto-tagging systems. It allows for quick and qualitative evaluation of individual and pairwise tag ...
  • Ferraro, Andrés; Jeon, Jea Ho; Kim, Biho; Serra, Xavier; Bogdanov, Dmitry (ICML, 2020)
    To evaluate if the recommendations are fair, we have to consider how all the stakeholders are affected. In this work, we focus on the artists in the music domain. We analyze the recommendations made with Collaborative ...
  • Meseguer, Pedro; Bouhmala, Noureddine; Bouzoubaa, Taoufik; Irgens, Morten; Sànchez Fibla, Martí (Springer, 2003)
    We summarize existing approaches to model and solve overconstrained problems. These problems are usually formulated as combinatorial optimization problems, and different specific and generic formalisms are discussed, ...
  • Miatton, Federico (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    5G propels mobile technology into the exclusive group of general purpose technologies that have marked the evolution of our history and triggered transformative changes in society. Edge computing is instrumental in helping ...
  • Bernardino Perez, Gabriel; Benkarim, Oualid M.; Sanz de la Garza, Maria; Prat Gonzàlez, Susanna; Sepúlveda Martínez, Álvaro; Crispi Brillas, Fàtima; Sitges, Marta; Butakoff, Constantine; De Craene, Mathieu; Bijnens, Bart; González Ballester, Miguel Ángel, 1973- (Elsevier, 2020)
    Statistical shape analysis is a powerful tool to assess organ morphologies and find shape changes associated to a particular disease. However, imbalance in confounding factors, such as demographics might invalidate the ...
  • Lai, I-Wei; Shih, Jhih-Wei; Chen, Kwang-Cheng; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Opportunistic links are emerging as a novel technology for state-of-the-art wireless networks, such as cognitive radio networks, energy-harvesting networks, and low-latency vehicular networks. To increase the reliability ...
  • Nikbakht, Rasoul; Mosayebi, Reza; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This letter proposes respective policies for uplink power control and downlink power allocation in cell-free wireless networks. Both policies rely only on large-scale quantities and are expressed in closed form, being ...
  • Attarifar, Masoud; Abbasfar, Aliazam; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    This paper formulates linear MMSE receivers that are both network- and user-centric for the uplink of cell-free wireless networks with centralized processing. Precisely, every user’s reception involves a distinct subset ...
  • Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Alarcón, Francisco; Caixal, Gala; Mont, Lluís; Camara, Oscar; Butakoff, Constantine (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Two-dimensional representation of 3D anatomical structures is a simple and intuitive way for analysing patient information across populations and image modalities. While cardiac ventricles, especially the left ventricle, ...
  • López Raventós, Álvaro; Bellalta, Boris (Elsevier, 2020)
    Enterprise Wireless Local Area Networks (WLANs) consist of multiple Access Points (APs) covering a given area. In these networks, interference is mitigated by allocating different channels to neighboring APs. Besides, ...
  • Pishtari, Gerti; Rodríguez-Triana, María Jesús; Sarmiento Márquez, Edna M.; Pérez Sanagustín, Maria del Mar; Ruiz Calleja, Adolfo; Santos Rodríguez, Patrícia; Prieto, Luis P.; Serrano Iglesias, Sergio; Väljataga, Terje (Wiley, 2020)
    Mobile and Ubiquitous Learning (m/u‐learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in ...
  • Cifra, Michal; Apollonio, Francesca; Liberti, Micaela; García Sánchez, Tomás; Mir, Lluis M. (Springer, 2020)
    Mechanisms of how electromagnetic (EM) field acts on biological systems are governed by the same physics regardless of the origin of the EM field (technological, atmospheric...), given that EM parameters are the same. We ...
  • Vohryzek, Jakub; Deco, Gustavo; Cessac, Bruno; Kringelbach, Morten L.; Cabral, Joana R. B. (Frontiers, 2020)
    Functionally relevant network patterns form transiently in brain activity during rest, where a given subset of brain areas exhibits temporally synchronized BOLD signals. To adequately assess the biophysical mechanisms ...
  • Carrascosa Zamacois, Marc; Bellalta, Boris (Elsevier, 2020)
    WiFi densification leads to the existence of multiple overlapping coverage areas, which allows user stations (STAs) to choose between different Access Points (APs). The standard WiFi association method makes STAs select ...
  • Cook, John; Mor, Yishay; Santos Rodríguez, Patrícia (Wiley, 2020)
    The paper contributes to design discourse by drawing on Educational Design Research (EDR) that has been conducted into what we call a Zone of Possibility (ZoP) over the past seven years. We define a ZoP as a place where ...
