    We formalise a specialised database management system model for time series using a multiresolution approach. These special purpose database systems store time series lossy compressed in a space-bounded storage. Time series ...
  • Sensibilidades de primero y segundo orden en circuitos lineales. Aplicación al desarrollo de un optimizador de la respuesta frecuencial 

    Miró Sans, Joan Maria; Palà Schönwälder, Pere (1991)
    Conference report
    Open Access
    Since using the Modified Nodal Approach formulation it is possible to obtain exact first and second arder sensitivities of any linear circuit with an affordable computational cost, first and second arder optimization ...
  • CiOpt: a program for optimization of the frequency response of linear circuits 

    Miró Sans, Joan Maria; Palà Schönwälder, Pere (IEEE Computer Society, 1991)
    Conference report
    Open Access
    An interactive personal-computer program for optimizing the frequency response of linear lumped circuits (CiOpt) is presented. CiOpt has proved to be an efficient tool in improving designs where the inclusion of more ...
  • Comunicaciones opticas no guiadas. Fotobalizaje 

    Miró Sans, Joan Maria; Miguel López, José María; Sanz Postils, Margarita (1991)
    Conference report
    Open Access
    After a brief overview of unguided optical communications, this paper presents a system for intelligent photo-buoying of vehicles which has been implementad into a public transport controlling system in a urban traffic ...
  • Prototipo experimental para ver y oir la dinámica caótica en un circuito 

    Miguel López, José María; Herranz Luis, Jaime; Miró Sans, Joan Maria; Palà Schönwälder, Pere; Sanz Postils, Margarita (1991)
    Conference report
    Open Access
    Chaos, apparently disordered behaviour which is nonetheless deterministic, is a universal phenomenon which occurs in many systems in all areas of science. For it to have place, the equations describing the situation must ...
  • Programa de simulación de circuitos analógicos lineales y de capacidades conmutadas

  • Design and performance comparison of a superregenerative MPSK transceiver 

    Bonet Dalmau, Jordi; López Riera, Alexis; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier; Babí Oller, Albert (2015)
    Conference lecture
    Open Access
    In this paper we present a superregenerative transceiver able to switch among BPSK, QPSK and 8PSK modulations. An HF-band proof-of-concept transceiver is implemented on an FPGA with a minimum of analog circuitry. The ...
  • Single cycle and transient force measurements in dynamic atomic force microscopy 

    Gadelrab, Karim Raafat; Santos, Sergio; Font Teixidó, Josep; Chiesa, Matteo (2013-11-21)
    Article
    Open Access
    The monitoring of the deflection of a micro-cantilever, as the end of a sharp probe mounted at its end, i.e. the tip, interacts with a surface, forms the foundation of atomic force microscopy AFM. In a nutshell, developments ...
  • Establishing nanoscale heterogeneity with nanoscale force measurements 

    Chang, Yun-Hsiang, Yun-Hsiang; Olukan, Tuza; Lai, Chia-Yun; Santos, Sergio; Lin, Tze-Yu; Apostoleris, Harry; Font Teixidó, Josep; Barcons Xixons, Víctor; Chiesa, Matteo (2015-08-13)
    Article
    Restricted access - publisher's policy
    Establishing the presence or absence of nanoscale compositional heterogeneity with nanoscale resolution is becoming instrumental for the development of many fields of science. Force versus distance measurements and parameters ...
