    • A simple method to estimate the return stroke current from close electric field measurements 

      Montañá Puig, Juan; Illa Arnau, Àngel; Hermoso Alameda, Blas; Romero Durán, David (2004)
      Conference lecture
      Restricted access - author's decision
      During summers 2003 and 2004 a measurement campaign was carried out over Catalonia (N-E of Spain). In these campaigns, lightning electrostatic field as well electric and magnetic fields were measured. This paper describes ...

    • Charge-induced force noise on free-falling test masses: results from LISA pathfinder 

      Armano, M.; Audley, H.; Auger, G.; Baird, J.; Binetruy, P.; Ramos Castro, Juan José (2017-04-26)
      Article
      Open Access
      We report on electrostatic measurements made on board the European Space Agency mission LISA Pathfinder. Detailed measurements of the charge-induced electrostatic forces exerted on free-falling test masses (TMs) inside the ...

    • Design of an apparatus for measuring atmospheric electrostatic fields 

      Cirera Jordana, Pol (Universitat Politècnica de Catalunya, 2014-06-20)
      Bachelor thesis
      Restricted access - author's decision
      The sky has always been something that the human race has tried to understand and use, in the first moments trying to imitate the birds and a way to fly and some steps further studying their composition; what we use to ...

    • Effect of dielectrophoretic force in the self-assembly process of electrosprayed nanoparticles 

      Castañer Muñoz, Luis María; Bermejo Broto, Sandra; Domínguez Pumar, Manuel (2017-03-31)
      Article
      Open Access
      In this work the effect of the dielectrophoretic force (DEP) in the self-assembly process of nanoparticles electrosprayed onto a substrate, is examined. DEP force is originated by the electric field created by the electrospray ...

    • Particle in cell simulation of electrostatic waves in Saturn's magnetosphere 

      Gasparin Pedraza, Laia (Universitat Politècnica de Catalunya / Kungl. Tekniska högskolan, 2012-09-05)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Kungliga Tekniska högskolan
      [ANGLÈS] The characteristics of electrostatic waves are investigated using PIC simulations of a four component plasma: cool and hot electrons, cool ions and an electron beam. The velocities are defined by Maxwellian ...

    • Short-range interactions of concentrated proline in aqueous solution 

      Busch, Sebastian; Lorenz, Christian D.; Taylor, Jonathan; Pardo Soto, Luis Carlos; McLain, Sylvia E. (2014-12-11)
      Article
      Restricted access - publisher's policy
      Molecular interactions for proline in a highly concentrated aqueous solution (up to 1:5 proline:water molecular ratio) have been investigated using a variety of experimental and computational techniques. Rather than the ...

    • Study of large-signal stability of an inverter-based generator using a Lyapunov function 

      Andrade, Fabio; Kampouropoulos, Konstantinos; Romeral Martínez, José Luis; Vasquez Quintero, Juan Carlos; Guerrero, Josep M. (2014)
      Conference report
      Open Access
      This document analyses the large-signal stability for an inverter-based generator such as photovoltaic and wind power sources. The objective of this study is to determine the stability region taking into account the ...

    • Testing assembly for directional Gecko inspired adhesives 

      Cañones Bonham, David Francesc (Universitat Politècnica de Catalunya, 2018-06)
      Bachelor thesis
      Open Access
      Covenantee:   Illinois Institute of Technology
      Gecko inspired adhesives are useful for situations where on/off states of adhesion are needed. Such adhesives are made of microstructured elastomers (usually a few microns in length) that are able to conform to a substrate ...
