  • Damping of Seismic Vibrations of a 3D Asymmetrical Building Model with Multiple TMD’s 

    Pinelli, Jean-Paul; Chen, Kai; Gutierrez, Hector; Rusovici, Razvan (2014-07)
    In this paper, the authors investigate the control of the seismic response of a three dimensional asymmetrical tier-building model, with a combination of three tuned mass dampers (TMD) located on the upper floor of the ...
  • Integrodifferential diffusion equation for continuous-time random walk 

    Wang, Kegang; Fa, Kwok Sau (2010-01-21)
    In this paper, we present an integrodifferential diffusion equation for continuous-time random walk that is valid for a generic waiting time probability density function. Using this equation, we also study diffusion behaviors ...
  • Continuous time random walk with generic waiting time and external force 

    Wang, Kegang (2010-05-20)
    We derive an integrodifferential diffusion equation for decoupled continuous time random walk that is valid for a generic waiting time probability density function and external force. Using this equation we also study ...
  • Shock interaction with one-dimensional array of particles in air 

    Sridharan, P.; Jackson, Thomas L.; Zhang, J.; Balachandar, S. (2015)
    In this paper, we present axisymmetric numerical simulations of shock propagation in air over an aluminum particle for Mach numbers up to 10. The numerical method is a finite-volume based solver on a Cartesian grid that ...
  • Singular behavior of the Debye-Waller factor of graphene 

    Tewary, Vinod K.; Yang, Bo (2009-03-16)
    It is shown that the mean-square displacement or the exponent of the Debye-Waller factor of graphene has a singularity except at zero temperature. The zero-temperature values of the mean-square displacement are calculated ...
  • Parametric interatomic potential for graphene 

    Tewary, Vinod K.; Yang, Bo (2009-02-27)
    A parametric interatomic potential is constructed for graphene. The potential energy consists of two parts: a bond energy function and a radial interaction energy function. The bond energy function is based on the ...
  • Road surface mirage: A bunch of hot air? 

    Zhou, Huaichun; Huang, Zhifeng; Cheng, Qiang; Lü, Wei; Qiu, Kui; Chen, Chen; Hsu, Peifeng (2011-04-20)
    The inferior mirage from road surfaces is a common phenomenon, which can be easily seen in everyday life. It has been recognized in the literature as a light refraction phenomenon due to the refractive index gradient caused ...
  • Hydrogenation of magnesium nanoblades: The effect of concentration dependent hydrogen diffusion 

    Yang, Bo; He, Yuping; Zhao, Yiping (2011-02-22)
    By assuming the H diffusion coefficient and H adsorption rate to be exponentially and linearly dependent on concentration, a physical model is developed to predict the hydrogenation process of Mg nanoblades. The predicted ...
  • Capillary-mediated dendritic branching 

    Glicksman, Martin E. (2012)
    We consider the Gibbs-Thomson temperature distribution as an active interface energy field with gradients and fluxes. Capillarity in conventional dendritic growth theories acts only as a passive boundary condition on the ...
