    • A framework for the definition of metrics for actor-dependency models 

      Franch Gutiérrez, Javier; Grau Colom, Gemma; Quer, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2004)
      Text en actes de congrés
      Accés obert
      The authors define actor-dependency models as a restricted class of goal-oriented models in which we focus on the actors and dependencies that exist in a system. An example of actor-dependency models are i* strategic ...

    • Analysis of the specific absorption rate in handset antennas with slotted ground planes 

      Picher, Cristina; Anguera Pros, Jaume; Puente Baliarda, Carles; Kahng, Sungtek; Andújar Linares, Aurora (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Text en actes de congrés
      Accés obert
      The study of the interaction between human head and handset antennas should be taken into account since all the mobile phones have to guarantee a biological compatibility. This research analyzes several antennas with ...

    • Convolutional neural networks for apnea detection from smartphone audio signals: effect of window size 

      Castillo Escario, Yolanda; Werthen Brabants, Lorin; Groenendaal, Willemijn; Deschrijver, Dirk; Jané Campos, Raimon (2022)
      Text en actes de congrés
      Accés obert
      Although sleep apnea is one of the most prevalent sleep disorders, most patients remain undiagnosed and untreated. The gold standard for sleep apnea diagnosis, polysomnography, has important limitations such as its high ...

    • How much can be reduced the internal FM antenna of mobiles phones? 

      Borja, C.; Anguera Pros, Jaume; Puente Baliarda, Carles; Vergés, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Text en actes de congrés
      Accés obert
      The paper introduces both a new internal FM antenna for mobile phones based on the fractal Hilbert curve, and a new evaluation criterion for quantifying the quality of the signal received by the FM antenna of mobile phones. ...

    • Human face segmentation and tracking using connected components and partition projection 

      Marqués Acosta, Fernando; Vilaplana Besler, Verónica; Buxes, A (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Text en actes de congrés
      Accés obert
      A new technique for segmenting and tracking human faces in video sequences is presented. The algorithm uses a connected operator to extract the connected component that more likely belongs to a face. Such a connected ...

    • Optimum watermark detection in color images 

      Sayrol Clols, Elisa; Vidal Manzano, José; Cabanillas, Silvia; Santamaria, Sonia (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Text en actes de congrés
      Accés obert
      This work concentrates on the problem of watermarking embedding and optimum detection in color images through the use of spread spectrum techniques both in space (Direct Sequence Spread Spectrum or DSSS) and frequency ...

    • The effect of walking on the estimation of breathing pattern parameters using wearable bioimpedance 

      Blanco Almazán, María Dolores; Groenendaal, Willemijn; Catthoor, Francky; Jané Campos, Raimon (2022)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Wearable bioimpedance is a technique proposed to estimate breathing parameters such as respiratory rate (RR). However, its potential application lies in clinical investigation of daily-life activities like walking. This ...
