      Text en actes de congrés
      Accés obert
      Rockfalls are frequent natural processes in mountain regions with the potential to produce damage. The quantitative risk analysis (QRA) is an approach increasingly used to assess risk and evaluate the performance of ...

    • On the influence of initial geometric imperfections and second order effects on the structural behavior of austenitic stainless steel frames 

      Shen, Yanfei; Chacón Flores, Rolando Antonio; Arrayago Luquin, Itsaso; Real Saladrigas, Esther (2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper presents a numerical and theoretical study from an ongoing research program focused on the structural behavior of austenitic stainless steel frames. Four different rectangular hollow sections (RHS) subjected to ...

    • An experimental study on the cyclic response of austenitic stainless steel 

      Chacón Flores, Rolando Antonio; de Marco, Mauricio; Real Saladrigas, Esther; Arrayago Luquin, Itsaso (2018)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Strain hardening is one of the key features of stainless steel for all structural applications. This property directly affects the definition of cross-sectional resistance, cross-section classification, ductility and energy ...

    • Turbulence behind 3D multi-scale sparse grids 

      Usama, Syed; Tellez Alvarez, Jackson David; Kopec, Jasek; Kwiatkowski, Kamil; Redondo Apraiz, José Manuel; Malik, Nadeem (Institute of Physics (IOP), 2018)
      Text en actes de congrés
      Accés obert
      A fundamentally new idea in grid generated turbulence is the 3D Sparse Grid (3DS) concept [N. A. Malik. Sparse 3D Multi-Scale Grid Turbulence Generator. US Patent No. US 9,599,269 B2 (2017)] which reduces the effective ...

    • Exploring paradigm shift impacts in urban mobility: autonomous vehicles and smart cities 

      Medina Tapia, Marcos Christian; Robusté Antón, Francesc (2018)
      Text en actes de congrés
      Accés obert
      Urban mobility is a dynamic system that has had a (slow) natural evolution. Scientists and engineers are currently developing new mobility technologies. A progressive paradigm shift will change everything from the fuel ...

    • Active superelasticity in three-dimensional epithelia of controlled shape 

      Latorre Ibars, Ernest; Kale, Sohan Sudhir; Casares, Laura; Arroyo Balaguer, Marino (Macmillan Publishers, 2018-11)
      Article
      Accés restringit per política de l'editorial
      Fundamental biological processes are carried out by curved epithelial sheets that enclose a pressurized lumen. How these sheets develop and withstand three-dimensional deformations has remained unclear. Here we combine ...

    • Simulation of high temperature superconductors and experimental validation 

      Olm Serra, Marc; Badia, Santiago; Martín Huertas, Alberto Francisco (2018-12)
      Article
      Accés restringit per política de l'editorial
      In this work, we present a parallel, fully-distributed finite element numerical framework to simulate the low-frequency electromagnetic behaviour of superconducting devices, which efficiently exploits high performance ...

    • Study and comparison of discontinuous modulation for modular multilevel converters in motor drive applications 

      Picas, Ricard; Zaragoza Bertomeu, Jordi; Pou, Josep; Ceballos Recio, Salvador; Konstantinou, Georgios; Capellá Frau, Gabriel José (Institute of Electrical and Electronics Engineers (IEEE), 2019-01-01)
      Article
      Accés obert
      Discontinuous modulation applied to modular multilevel converters is an effective method for reducing the capacitor voltage ripples. In this paper, the discontinuous modulation is adapted and used in a motor drive application. ...

    • Effect of variable solar irradiance on the reactive power response of photovoltaic Generators 

      Cabrera Tobar, Ana; Aragüés Peñalba, Mònica; Gomis Bellmunt, Oriol (2018)
