      1D model for the energy yield calculation of natural convection solar air collectors 

      Demou, A. D.; Grigoriadis, D. G. E. (2018)
      A one dimensional model has been developed and presented to calculate the seasonal energy yield of solar air collectors. This model takes into account local meteorological conditions, the effects of geometrical configuration, ...

      Are any growth theories robust? 

      Durlauf, Steven N.; Kourtellos, Andros; Tan, Chih Ming (2008)
      This article investigates the strength of empirical evidence for various growth theories when there is model uncertainty with respect to the correct growth model. Using model averaging methods, we find little evidence that ...

      A consistent velocity approximation for variable-density flow and transport in porous media 

      Albets-Chico, X.; Kassinos, Stavros C. (2013)
      Using a finite-volume nodal-based code, we introduce a new consistent numerical scheme for approximating the seepage velocity in variable-density flow in porous media. It has been known from previous works that the lack ...

      Controlling illegal immigration: ON the scope for cooperation with a transit country 

      Djajic, Slobodan; Michael, Michael S. (2014)
      We consider the implications of cooperation with respect to immigration control between a final-destination country (D) and its poorer neighbor (T). Assuming that the latter serves as a transit country for undocumented ...

      Core of the magnetic obstacle 

      Votyakov, E. V.; Kassinos, Stavros C. (2010)
      Rich recirculation patterns have been recently discovered in the electrically conducting flow subject to a local external magnetic termed "the magnetic obstacle" (E.V. Votyakov, Y. Kolesnikov, O. Andreev, E. Zienicke, and ...

      Dispersed-phase structure in sheared MHD turbulence 

      Xu, X.; Rouson, D. W. I.; Kassinos, Stavros C.; Radhakrishnan, H. (2012)
      Direct numerical simulations are performed to examine particle dispersion in homogeneous turbulence subjected to mean shear and an externally applied magnetic field. We employ the Brucker et al. algorithm for simulating ...
