  • Precision timing in ocean sensor systems 

    Río Fernandez, Joaquín del; Mihai Toma, Daniel; Shariat Panahi, Shahram; Manuel Lázaro, Antonio; Geirinhas Ramos, Helena María (2011-12-16)
    Article
    Open Access
    This paper discusses the use of the IEEE 1588 standard in ocean observatories. The performance result of prototype implementations of this standard in an Ethernet Marine Sensor Network (MSN) is presented. The performance ...
  • Precision timing in TDMA - based Wireless Sensor Network through IEEE 1588 standard 

    Toma, Daniel; Río Fernandez, Joaquín del; Manuel Lázaro, Antonio; Gomáriz Castro, Spartacus; Carreras Pons, Normandino (2013)
    Conference report
    Open Access
    This paper proposes an energy-efficient time synchronization scheme for Wireless Sensor Networks(WSNs) based on the IEEE 1588 standard. Although a number of methods have been studied for time synchronization of WSNs, some ...
  • Smart IEEE-1588 GPS clock emulator for cabled ocean sensors 

    Río Fernandez, Joaquín del; Toma, Daniel Mihai; Shariat Panahi, Shahram; Auffret, Yves; Manuel Lázaro, Antonio (2014-04-02)
    Article
    Restricted access - publisher's policy
    Today, cabled seafloor observatories are installed at many sites around the globe, gathering different types of sensors in the marine environment where a Global Positioning System (GPS) signal is not accessible. Accurate ...
  • Time-domain electromagnetic interference measurement system for intermittent disturbances 

    Costa Godo, Gerard; Pous Solà, Marc; Atienza Picola, Andreu; Silva Martínez, Fernando (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    In Electromagnetic Compatibility emission measurements, a common problem takes place when equipment producing intermittent disturbances are measured according to standard procedures. In many cases, it is impossible to ...
  • Voltage balancing of a five-level flying capacitor converter using optimum switching transitions 

    Ghias, Amer M.Y.M.; Pou Félix, Josep; Ciobotaru, M.; Agelidis, Vassilios (2012)
    Conference report
    Open Access
    The flying capacitor (FC) multilevel converter requires a capacitor voltage balancing mechanism for proper operation. This paper proposes a voltage balancing scheme for a five-level FC converter based on phase disposition ...
