A novel multi-scale numerical model for prediction of texture-related impacts on fuel consumption [PDF]
, 2017 It is estimated that to overcome rolling resistance (RR) a typical vehicle, on average, consumes 4152 MJ/119 L of fuel annually, depending not only on vehicle-related factors but also on pavement-related factors.

Fluctuating Nonlinear Spring Model of Mechanical Deformation of Biological Particles [PDF]
, 2015 We present a new theory for modeling forced indentation spectral lineshapes of biological particles, which considers non-linear Hertzian deformation due to an indenter-particle physical contact and bending deformations of curved beams modeling the ...
