In this study we evaluated the performance of a newly developed multi-layer energy budget (Ryder et al., 2014) in a land surface model, ORCHIDEE-CAN (Naudts et al., 2014),

The entrained lighter fluid from the upper layer will be carried downward and the heavy fluid (entrained from the lower layer) will be carried upward by the overturning

In other words, if one considers, as in RMZL12, that the source of tidal dissipation is restricted to the core, it seems obvious that one has to relate the tidal dissipation in the

In the hope of attaining better local minima, and inspired by optimization techniques used in deep learning [6], the proposed approach summarized in Algorithm 1 is a

The optimization of the final thickness profile is generally achieved by trial and error, changing the design of the component, the polymer material, and the process parameters such
