    Article
    Open Access
    Media use cases for emergency services require mission-critical levels of reliability for the delivery of media-rich services, such as video streaming. With the upcoming deployment of the fifth generation (5G) networks, a ...
  • A universal specification for multicore fiber crosstalk 

    Gené Bernaus, Joan M.; Winzer, Peter J. (2019-05-01)
    Article
    Open Access
    In order to transition multi-core fiber (MCF) technologies from their research state to volume production, the key design specifications have to be broadly agreed upon, first and foremost an acceptable level of inter-core ...
  • Large eddy simulation and laboratory experiments on the decay of grid wakes in strongly stratified flows 

    Fraunie, P.; Chashechkin, Y.; Redondo Apraiz, José Manuel; Velasco Montes, David; Rayo Berreba, S. (2009-07-27)
    Article
    Open Access
    A detailed analysis of the flow structure resulting from the combination of turbulence and internal waves is carried out and visualized by means of the Schlieren method on waves in a strongly stratified fluid at the ...
  • The dichotomy of distributed and centralized control: METRO-HAUL, when control planes collide for 5G networks
