      Text en actes de congrés
      Accés restringit per política de l'editorial
      The problem of testing whether a packet belongs to a set of filtered addresses has been traditionally addressed using Bloom filters. They have a small memory footprint and require few memory accesses per query and insertion, ...

    • A reliable statistical analysis of the best-fit distribution for High Execution Times 

      Civit, Xavier; Castillo, Joan del; Abella Ferrer, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Comunicació de congrés
      Accés obert
      Extreme Value Theory has been used to model the WCET probabilistically, relying on the assumption that probabilistic WCET (pWCET) estimates can be upper-bounded with exponential distributions, but this is only assessed on ...

    • Coagulation time detection by means of a real-time image processing 

      Gasull Llampallas, Antoni; Vallverdú Bayés, Sisco; Marqués Acosta, Fernando (. IEEE, 1992)
      Text en actes de congrés
      Accés obert
      Several techniques for semi-automatic or automatic detection of coagulation time in blood or in plasma analysis are available in the literature. However, these techniques are either complex and demand for specialized ...

    • Coping with the variability of combinational logic delays 

      Cortadella, Jordi; Kondratyev, Alex; Lavagno, Luciano; Sotiriou, Christos P. (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      Text en actes de congrés
      Accés obert
      This paper proposes a technique for creating a combinational logic network with an output that signals when all other outputs have stabilized. The method is based on dual-rail encoding, and guarantees low timing overhead ...

    • Error analysis and reduction for a simple sensor-microcontroller interface 

      Custodio Ruiz, Ángel; Pallàs-Areny, Ramon; Bragós Bardia, Ramon (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-12-31)
      Article
      Accés obert
      Error analysis of a resistive sensor-to-microcontroller interface based on pulse-width modulation and time–ratio measurement shows that internal input and output resistances in microcontroller digital ports produce zero, ...

    • Evaluation of clustering techniques for efficient searching in JXTA-based P2P systems 

      Xhafa Xhafa, Fatos; Jaen, Enric; Daradoumis, Thanasis; Barolli, Leonard (Institute of Electrical and Electronics Engineers (IEEE), 2008)
      Text en actes de congrés
      Accés obert
      The efficient file searching is an essential feature in P2P systems. While many current approaches use brute force techniques to search files by meta information (file names, extensions or user-provided tags), the interest ...

    • Event-IMU fusion strategies for faster-than-IMU estimation throughput 

      Chamorro Hernández, William Oswaldo; Solà Ortega, Joan; Andrade-Cetto, Juan (2023)
      Comunicació de congrés
      Accés obert
      This study presents new methods for integrating event data and IMU readings to achieve ultra-fast camera pose estimates. The conventional predict-with-IMU-correct-with-vision approach is no longer optimal because events ...

    • Guaranteed state estimation and fault detection based on zonotopes for differential-algebraic-equation systems
