  • A model for a multiresolution time series database system 

    Llusà Serra, Aleix; Escobet Canal, Teresa; Vila Marta, Sebastià (WSEAS Press, 2013)
    Conference report
    Open Access
    In this paper we propose a model for multiresolution time series database management systems. Thismodel stores compactly a time series and manages consistently its temporal dimension. This is achieved byextracting different ...
  • Health-aware model predictive control of wind turbines using stifness degradation approach 

    Eloy Sanchez, Hector; Escobet Canal, Teresa; Puig Cayuela, Vicenç (2020)
    Conference report
    Open Access
    Wind turbine blades are under signi cant gravitational, inertial, and aero-dynamic loads, which cause their fatigue and degradation during the wind turbine operational life. The present work proposes a Model Predictive ...
  • Fault detection and identification in a fuel cell system 

    Escobet Canal, Antoni; Nebot Castells, M. Àngela (IOS Press, 2009)
    Conference report
    Restricted access - publisher's policy
    In this work a fault diagnosis system for non-linear plants based on fuzzy logic, called VisualBlock-FIR, is presented and applied to an energy generation system based on fuel cells. VisualBlock-FIR runs under the Simulink ...

    The “EXPLORATORI” is a project from the Universitat Politècnica de Catalunya (UPC) and the Berga Town Council. The main objective of the project is to bring science closer to secondary school students, their teachers and ...
  • Fracture mechanics based modelling of failure in advanced high strength steels 

    Jonsén, Par; Frómeta Gutiérrez, David; Casellas Padró, Daniel (2017)
    Conference report
    Open Access
    In the last decade, the favorable properties of the press hardening process for advanced high strength steel (AHSS) have increased the demands concerning passenger safety and lightweight design. AHSS show excellent mechanical ...
  • Determination of the essential work of fracture at high strain rates 

    Frómeta Gutiérrez, David; Casellas Padró, Daniel; Jonsén, Par (2017)
    Conference report
    Open Access
    During the last decades, the use of ultra-high strength steel (UHSS) has increased as its favorable ratio between strength and mass allows the design of lighter body-in-white while maintaining passenger safety. Modeling ...
  • 3D-printing and computational fluid dynamics "meet" paperbased microfluidics for enhanced flow control in difusive sensors 

    López Martínez, Joan Antoni; Fernández, Pau; Mehrdel, Pouya; Casals Terré, Jasmina (2020)
    Conference lecture

    This paper proposes combination of a 3D printed cartridge and paper-based microfluidic design that minimizes the amount of sample required to achieve the best control over the diffusion Y-microfluidic mixers. The use of ...
  • Software-based implementation of dual connectivity for LTE 

    Pupiales Yépez, Carlos; Nitzold, Walter; Felber, Clemens; Demirkol, Ilker Seyfettin (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    One of the major challenges of current mobile networks is to increase the per-user data rate without significant infrastructure cost and using the already existing physical resources, i.e., the bandwidth. In this sense, ...
