A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003
(2008)Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...

Growth and characterization of ceria thin films and Ce-doped γ - Al 2 O 3 nanowires using sol-gel techniques
(2010)γ - Al 2 O 3 is a well known catalyst support. The addition of Ce to γ - Al 2 O 3 is known to beneficially retard the phase transformation of γ - Al 2 O 3 to α - Al 2 O 3 and stabilize the γ-pore structure. In this ...

Growth and structural characterization of orthorhombic and tetragonal SrCuO2 thin films
(2013)Epitaxial SrCuO2 thin films were grown on (0 0 1) SrTiO 3 substrates by pulsed laser deposition using a stoichiometric target. X-ray diffraction indicated that the SrCuO2 films undergo a structural phase transition as a ...

Hall effect above Tc in untwinned single-crystal YBa2Cu3O7-x: Normal-state behavior and superconducting fluctuations
(1991)We present a measurement of the Hall coefficient RH for an untwinned single crystal of YBa2Cu3O7-x. The crystal was produced by a method that does not involve thermomechanical detwinning, and has a resistivity along the ...

Hardware acceleration of n-body simulations for galactic dynamics
(Affiliation: Rutgers Univ., Piscataway, NJ, USA, United StatesCorrespondence Address: Cook, Todd A.Rutgers Univ., Piscataway, NJ, USAUnited States, 1995)N-body methods are used to simulate the evolution and interaction of galaxies. These simulations are usually run on large-scale supercomputers or on very expensive full-custom hardare. This paper presents an alternative ...
