    • Excitation of multiple spatial modes of a MENS cantilever in the pulsed digital oscillator 

      Blokhina, Elena; Feely, Orla; Domínguez Pumar, Manuel (IEEE Press. Institute of Electrical and Electronics Engineers, 2009)
      Conference report
      Open Access
      The aim of this paper is to apply an approach that will allow us to consider different mechanical modes of a MEMS cantilever in the form of separate mass-spring-damper equations with the appropriate form of an external ...

    • Exploring the performance of a miniature 3D wind sensor under extreme martian winds up to the dust devil scale 

      Domínguez Pumar, Manuel; Kowalski, Lukasz; Jiménez Serres, Vicente; Rodríguez Pérez, Ivette María; Soria Guerrero, Manel (2019)
      Conference report
      Open Access
      The objective of this paper is to explore the performance of a miniature 3D spherical wind sensor for Mars atmosphere, working under extreme wind speeds, up to the Dust Devil scale. The experimental campaign has been made ...

    • Fluid dynamics and heat transfer in the wake of a sphere 

      Rodríguez Pérez, Ivette María; Lehmkuhl Barba, Oriol; Soria Guerrero, Manel; Gómez, Samuel; Domínguez Pumar, Manuel; Kowalski, Lukasz (2019-04)
      Article
      Open Access
      Direct numerical simulation and large-eddy simulation have been performed for a heated sphere at Reynolds numbers of $Re=1000$ and $Re=10^4$, respectively. The Prandtl number for both simulations has been $Pr=0.7$. ...

    • General dynamics of pulsed digital oscillators 

      Domínguez Pumar, Manuel; Pons Nin, Joan; Ricart Campos, Jordi (IEEE, 2008-02-08)
      Article
      Open Access
      The objective of this work is to analyze pulsed digital oscillators (PDOs), as dynamical systems. It is proved that under some conditions, the bitstream at the output of the oscillator is that of the sign of a sampled ...

    • Heat flow dynamics in thermal systems described by diffusive representation 

      Domínguez Pumar, Manuel; Atienza García, María Teresa; Kowalski, Lukasz; Novio Vázquez, Santiago; Gorreta Mariné, Sergio; Jiménez Serres, Vicente; Silvestre Bergés, Santiago (Institute of Electrical and Electronics Engineers (IEEE), 2016-09-01)
      Article
      Open Access
      The objective of this paper is to analyze the dynamics of heat flow in thermal structures working under constant temperature operation. This analysis is made using the tools of sliding mode controllers. The theory is ...
