A steady-state model of NEA binaries formed by tidal disruption of gravitational aggregates
Asteroids dynamics Satellites of asteroids
<
2015/12/25
We present results of a simulation of a steady-state binary near-Earth asteroid (NEA) population. This study combines previous work on tidal disruption of gravitational aggregates [Walsh, K.J., Richar...
A semi-analytical solution to accelerate spin-up of a coupled carbon and nitrogen land model to steady state
The spin model The steady state coupling Ecosystems Carbon transfer
<
2014/12/10
The spin-up of land models to steady state of coupled carbon–nitrogen processes is computationally so costly that it becomes a bottleneck issue for global analysis. In this study, we introduced a semi...

2011/9/13
We develop a comparative thermodynamic theory, based on master-equation description of driven chemical reactions, for quasi-steady-state (QSS) and open-system nonequilibrium steady-state (NESS) sustai...
Local structure of the set of steady-state solutions to the 2D incompressible Euler equations
Local structure of the set steady-state solutions 2D incompressible Euler equations
