  • Superregenerative reception of narrowband FSK modulations 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; López Riera, Alexis; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2015-03-01)
    Article
    Open Access
    In this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different ...
  • Forward backward asymmetries of lepton pairs in events with a large transverse momentum jet at hadron colliders 

    Águila López, Francisco del; Ametller Congost, Lluís; Talavera Sánchez, Pedro (2002-10)
    Article
    Open Access
    We discuss forward-backward charge asymmetries for lepton-pair production in association with a large-transverse-momentum jet at hadron colliders. The lepton charge asymmetry relative to the jet direction AjFB gives a new ...
  • A low in-band radiation superregenerative oscillator 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2013-05-27)
    Article
    Open Access
    This brief describes a superregenerative (SR) voltage-controlled oscillator as a building block for SR receivers where most of the oscillator spectrum components are outside the reception frequency band. This allows ...
  • Unlocking higher harmonics in atomic force microscopy with gentle interactions 

    Santos Hernández, Sergio; Barcons Xixons, Víctor; Font Teixidó, Josep; Verdaguer Prats, Albert (2014-03-11)
    Article
    Open Access
    In dynamic atomic force microscopy, nanoscale properties are encoded in the higher harmonics. Nevertheless, when gentle interactions and minimal invasiveness are required, these harmonics are typically undetectable. Here, ...
  • A superregenerative QPSK receiver 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2014-01)
    Article
    Open Access
    In this paper we present a description and experimental verification of a superregenerative receiver (SR) for QPSK signals. Exploiting the fact that a conventional SR generates pulses which preserve the input phase ...
  • Stability, resolution, and ultra-low wear amplitude modulation atomic force microscopy of DNA: small amplitude small set-point imaging 

    Santos Hernández, Sergio; Barcons Xixons, Víctor; Christenson, Hugo K.; Billingsley, Daniel J.; Bonass, William A.; Font Teixidó, Josep; Thomson, Neil H. (2013)
    Article
    Open Access
    A way to operate fundamental mode amplitude modulation atomic force microscopy is introduced which optimizes stability and resolution for a given tip size and shows negligible tip wear over extended time periods ( 24 ...
  • Improving symbolic language comprehension 

    Alsina Aubach, Montserrat; Bonet Dalmau, Jordi (2013)
    Conference report
    Open Access
    We focus on the goal of “Handling mathematical symbols and formalism” through the methodology of Content and Language Integrated Learning. The use of foreign language highlights, and possibly increases, the difficulties ...
  • Elaboració de recursos multimèdia per a l'ensenyament/aprenentatge en anglès en graus tecnològics 

    Alsina Aubach, Montserrat; Fortuny Santos, Jordi; Giralt Mas, Ma. Rosa (Octaedro, 2012)
    Conference report
    Open Access
    En aquest article es presenta el procés d'elaboració de recursos per a la impartició d'assignatures en anglès a l'ensenyament superior. Els principals resultats són les aplicacions Class-Talk i Multilingual Formulae, ...
  • Eines de la web 2.0 per a la coordinació d'assignatures: resultats preliminars 

    Giralt Mas, Ma. Rosa; Bonet Dalmau, Jordi; Vila Marta, Sebastià; Palà Schönwälder, Pere; Águila López, Francisco del (2012)
    Conference lecture
    Open Access
    Aquesta comunicació presenta els resultats d'utilització d'un Dipòsit de Material Docent amb les característiques pròpies de l'Open Course Ware, en el primer quadrimestre del nou grau en Enginyeria de Sistemes TIC que ...
  • Teaching symbolic language to non-native speakers 

    Bonet Dalmau, Jordi; Alsina Aubach, Montserrat (2012)
    Conference lecture
    Restricted access - publisher's policy
    In this paper, we describe how an on-line resource, primarily intended to improve the proficiency in a foreign language, can also facilitate the understanding of the symbolic language in an engineering degree course. We ...
