      Article
      Accés obert
      The circulation of CO2-rich solutions through fractured marl cores (caprock) under different flow rates and supercritical CO2 conditions (PTotal = 150 bar, pCO2 = 61 bar and T = 60 °C) led to mineral changes caused mainly ...

    • A review of gerotor technology in hydraulic machines 

      Gámez Montero, Pedro Javier; Codina Macià, Esteban; Castilla López, Roberto (2019-06-24)
      Article
      Accés obert
      Over the years, numerous investigations have established the gerotor fundamentals. This work aims to provide a complete review of the literature from the last decade, focusing on the articles published in the past five ...

    • A smart textile system to detect urine leakage 

      Martínez Estrada, Marc; Gil Galí, Ignacio; Fernández García, Raúl (2021-05-17)
      Article
      Accés obert
      In this paper a wearable system with a sensor embroidered on a textile substrate to detect urine leaks is presented. The system consists of a moisture textile capacitive sensor together with the signal conditioning and its ...

    • Demand modeling for water networks calibration and leak localization 

      Sanz Estapé, Gerard (Universitat Politècnica de Catalunya, 2016-03-18)
      Tesi
      Accés obert
      The success in the application of any model-based methodology (e.g. design, control, supervision) highly depends on the availability of a well calibrated model. There is no best or unique solution for the calibration problem ...

    • Dynamic selective devectorization for efficient power gatting of SIMD units in a HW/SW co-designed enviromment 

      Kumar, Rakesh; Martínez, Alejandro; González Colás, Antonio María (IEEE Computer Society Publications, 2013)
      Text en actes de congrés
      Accés obert
      Leakage power is a growing concern in current and future microprocessors. Functional units of microprocessors are responsible for a major fraction of this power. Therefore, reducing functional unit leakage has received ...

    • Effects of Rotation on the Flow Structure in a Compressor Cascade 

      Ventosa Molina, Jordi; Koppe, Björn; Lange, Martin; Mailach, Ronald; Fröhlich, Jochen (American Society of Mechanical Engineers (ASME), 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In turbomachines, rotors and stators differ by the rotation of the former. Hence, half of each stage is directly influenced by rotation effects. The influence of rotation on the flow structure and its impact on the performance ...

    • Leakage localization in water distribution using data-driven models and sensitivity analysis 

      Jensen, Tom Nørgaard; Puig Cayuela, Vicenç; Romera Formiguera, Juli (2018-01-01)
      Article
      Accés restringit per política de l'editorial
      Water scarcity is becoming an increasing problem worldwide, and an issue compounding the problem is water leakage in the piping networks delivering potable/consumable water to end-users (Sensus, 2012). In this paper, we ...

    • Multi Jet Fusion PA12 manufacturing parameters for watertightness, strength and tolerances 

      Morales Planas, Sergio; Minguella Canela, Joaquim; Llumà Fuentes, Jordi; Travieso Rodríguez, José Antonio; García Granada, Andrés-Amador (Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-18)
      Article
      Accés obert
      The aim of this paper is to explore the watertightness behaviour for high pressure applications using Multi Jet Fusion technology and polyamide 12 as a material. We report an efficient solution for manufacturing functional ...

    • Study of Relative Endwall Motion Effects in a Compressor Cascade Through Direct Numerical Simulations
