    • A framework for structural systems based on the principles of statistical mechanics 

      Andújar Moreno, Rabindranath; Roset Calzada, Jaime; Kilar, Vojko (2014-11)
      Article
      Accés obert
      A framework is proposed in which certain well-known concepts of statistical mechanics and thermodynamics can be used and applied to characterize structural systems of interconnected Timoshenko beam elements. We first make ...

    • Determination of a System’s Entropy Using Pyroelectric Sensors 

      Cuadras Tomàs, Àngel; Ovejas Benedicto, Victòria Júlia (2015-12)
      Article
      Accés obert
      We propose a system for measuring entropy variations, S, in thermal systems using pyroelectric sensors. These sensors convert time-dependent temperature variations into electrical current. Consequently, heat and ...

    • Determination of groundwater flow based on temperature data 

      Casanovas López-Amor, Carlos (Universitat Politècnica de Catalunya, 2016-06-23)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Consejo Superior de Investigaciones Científicas
      Different techniques have been used to measure the groundwater flow velocity but they are either too invasive or too inaccurate. In the present study two analytical solutions have been developed and tested to determine ...

    • Estudio experimental y modelización matemática de dardos de fuego 

      Gómez Mares, Mercedes (Universitat Politècnica de Catalunya, 2009-11-27)
      Tesi

    • Thermal Rendering 

      Juncà i Sabrià, Albert (Universitat Politècnica de Catalunya, 2015-07-08)
      Projecte Final de Màster Oficial
      Accés obert
      A method for heat transfer that combines heat conduction and radiation. Our solution uses an explicit finite differences scheme for the heat conduction equation and a direct radiosity Monte Carlo technique to compute sun ...
