  • Sfairopoulou, Anna; Bellalta, Boris; Macián, Carlos; Oliver Riera, Miquel (Springer Verlag, 2010)
    In multi-rate WLANs, users can suffer transmission rate changes due to the link adaptation mechanism. This results in a variable capacity channel, which is very hostile for VoIP and can cause serious quality of service ...
  • Sfairopoulou, Anna (Universitat Pompeu Fabra, 2011-04-12)
    In IEEE 802.11 WLANs, Link Adaptation mechanisms, which choose the transmission rate of each node, provoke unexpected and random variations on the effective channel capacity. When these changes are towards lower bitrates, ...
  • Della Valle, Fabio; Oliver Riera, Miquel (MDPI, 2021)
    Blockchains play a crucial role in the digitalization of future supply chains (SCs). In this study, we analyzed the major influences that blockchain-based digital business strategies may play in SC operations. We conducted ...

    Through advances in sensor, networking, semiconductor and energy storage technologies, Wireless Sensor Networks (WSNs) are increasingly being deployed in many important applications to enable users to access information ...
  • Bellalta, Boris; Daza, Vanesa; Oliver Riera, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    A queueing model for Multi-rate Multi-user MIMO systems is presented. The model is built upon the assumption that the probability distribution of available destinations among the buffered frames at the Base Station (BS) ...
  • Albó, Laia; Hernández Leo, Davinia; Oliver Riera, Miquel (2016)
    Most MOOCs offer open learning opportunities at Higher Education (HE) level./nHowever, it is still unclear how HE students are taking this type of course. This/nstudy focuses on the profile of HE students participating in ...
  • Albó, Laia; Hernández Leo, Davinia; Oliver Riera, Miquel (CEUR Workshop Proceedings, 2015)
    Blended Massive Open Online Courses (bMOOCs) have arisen as a blended learning strategy that combines the use of MOOC platform-supported activities and video-based content with in-class face-to-face activities in Higher ...
  • Della Valle, Fabio; Oliver Riera, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Supply chain management is considered one of the main sectors of development for blockchain technology. This study provides solid contributions to understanding blockchain innovation and presents some main features and ...

    This thesis presents a study of blockchain impacts for supply chain (SC) application. By conducting explorative research, the thesis presents a grounded theory analysis based on eighteen interviews with international experts ...
  • Della Valle, Fabio; Oliver Riera, Miquel (MDPI, 2021)
    Performance measurement and information management are vital assets for supply chain management. In this study, we analyzed the effective combination between blockchain technologies and supply chain management processes. ...
  • Barceló Vicens, Jaume (Universitat Pompeu Fabra, 2011-04-12)
    Aquesta tesi suggereix usar un compte enrere determinista després de les transmissions exitoses en les xarxes d'àrea local sense fils. Com que les estacions que han transmès amb èxit en el seu darrer intent no poden ...
  • Oliveira, Thays Aparecida de; Oliver Riera, Miquel; Ramalhinho-Lourenço, Helena (MDPI, 2020)
    The way citizens interact with cities affects overall life quality. Their participation in social decisions is of paramount importance for helping on public decisions that affect governance, regulation and education. This ...
  • Sanabria-Russo, Luis (Universitat Pompeu Fabra, 2016-11-23)
    Using a deterministic backoff after successful transmissions as a distributed contention mechanism for access to the channel can draw benefits from scheduled operation, like the elimination of simultaneous transmissions, ...
