Primordial Gravitational Waves in Bimetric Gravity [PDF]
, 2015 We study primordial tensor power-spectra generated during inflation in bimetric gravity. More precisely, we examine a homogeneous expanding spacetime in a minimal bimetric model with an inflaton and calculate tensor perturbations on the homogeneous ...

Modulation of internal estimates of gravity during and after prolonged roll-tilts. [PDF]
PLoS ONE, 2013 Perceived direction of gravity, as assessed by the subjective visual vertical (SVV), shows roll-angle dependent errors that drift over time and a bias upon return to upright.

Nonlinear roll damping of a barge with and without liquid cargo in spherical tanks
Journal of Ocean Engineering and Science, 2016 Damping plays a significant role on the maximum amplitude of a vessel's roll motion, in particular near the resonant frequency. It is a common practice to predict roll damping using a linear radiation–diffraction code and add that to a linearized viscous

Mechanistic driving force for martensite decay in rolling contact fatigue
Tribology International, 2023 Martensite decay due to large scale microstructural alterations is the main fatigue process which occurs during extensive rolling contact fatigue in bearing applications. Despite its practical and scientific importance, the full description of the controlling phenomena is still incomplete.

Exponential Decay of Contact-patch Friction Steering Moment with Rolling Speed
, 2021 Steering torque is a very important quantity for the driver feeling. In fact, it gives the driver an idea of the road adherence condition during driving. Several models have been developed to simulate shear forces at the contact patch, most of them are based on semi-empirical tire models that account for slip and slip angles. They have good reliability
