  • Anharmonicity in multifrequency atomic force microscopy 

    Santos Hernandez, Sergio; Barcons Xixons, Víctor (2014-07)
    Report de recerca
    Accés obert
    In multifrequency atomic force microscopy higher eigenmodes are externally excited to enhance resolution and contrast while simultaneously increasing the number of experimental observables with the use of gentle forces. ...
  • Deconstructing the governing dissipative phenomena in the nanoscale 

    Santos Hernandez, Sergio; Amadei, Carlo Alberto; Tang, Tzu-Chieh; Barcons Xixons, Víctor; Chiesa, Matteo (2014-01)
    Report de recerca
    Accés obert
    An expression describing the controlling parameters involved in short range nanoscale dissipation is proposed and supported by simulations and experimental findings. The expression is deconstructed into the geometrical, ...
  • Wearing a single DNA molecule with an AFM tip 

    Santos Hernandez, Sergio; Barcons Xixons, Víctor; Font Teixidó, Josep; Thomson, Neil H. (2015-06)
    Report de recerca
    Accés obert
    While the fundamental limit on the resolution achieved in an atomic force microscope (AFM) is clearly related to the tip radius, the fact that the tip can creep and/or wear during an experiment is often ignored. This is ...
  • Informe sobre la Competència de Sostenibilitat i Compromís Social a la Universitat Politècnica Catalunya

  • Tools to deal with under-constrained geometric constraint graphs 

    Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià (2003-12)
    Report de recerca
    Accés obert
    We present tools for handling geometric constraint problems with under-constrained configurations. The basic idea is to add to the given set of constraints a set of extra constraints which can be defined either automatically ...
  • Detecció i identificació de falles en una xarxa de distribució d'aigües 

    Escobet Canal, Antoni; Nebot Castells, M. Àngela (2001-04)
    Report de recerca
    Accés obert
    This technical report deals with two of the main tasks of Fault Monitoring Systems (FMS): fault detection and fault identification. During fault detection, the FMS should recognize that the plant behavior is abnormal, ...
  • Declarative characterization of a general architecture for constructive geometric constraint solvers 

    Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià; Vilaplana Pasto, Josep (2002-02)
    Report de recerca
    Accés obert
    Geometric constraint solving is a growing field devoted to solve geometric problems defined by relationships, called constraints, established between the geometric elements. There are several techniques to solve ...
  • Revisiting decomposition analysis of geometric constraint graphs 

    Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià; Vilaplana Pasto, Josep (2002-02)
    Report de recerca
    Accés obert
    Geometric problems defined by constraints can be represented by geometric constraint graphs whose nodes are geometric elements and whose arcs represent geometric constraints. Reduction and decomposition are techniques ...
  • Transforming an under-constrained geometric constraint problem into a well-constrained one 

    Joan Arinyo, Robert; Soto Riera, Antoni; Vila Marta, Sebastià; Vilaplana Pasto, Josep (2002-12)
    Report de recerca
    Accés obert
    We present an approach for handling geometric constraint problems with under-constrained configurations. The approach works by completing the given set of constraints with constraints that can be defined either ...
  • Desarrollo de una aplicación CAE para el diseño de circuitos de ventilación 

    Ayala Vallespí, M. Dolors; Pla García, Núria; Soto Riera, Antoni; Vigo Anglada, Marc; Vila Marta, Sebastià (1999-07)
    Report de recerca
    Accés obert
    En este trabajo se presenta una aplicacion CAE para el diseno de circuitos de ventilacion. En ella se han desarrollado aspectos de diseno del modelo, de la interaccion con el usuario y de simulacion del comportamiento ...
