The rate of decreasing altitude (semimajor axis) depends on the ballistic parameter B \({(B= C}_{D}\frac{A}{m}\)) and the increasing drag shown by Eq. (2). As previously explained, the increased drag is caused
On the one end is simple ballistic motion, which describes straight-line movement of individuals in random directions (Mosimann, 1958, Gerritsen, Strickler, 1977, Hutchinson, Waser, 2007). On the other extreme is Brownian motion (BM), which describes infinitely tortuous trajectories (Visser, K...
For our purposes it is set to 1.0. This is because the drift coefficient is a scaling parameter; that is, if the parameter were doubled, other parameters of the model could be doubled to produce exactly the same predictions. However, with multiple conditions we can estimate how this noise...
The noise in each sample is determined by the parameter σ 2 called the drift coefficient. For our purposes it is set to 1.0. This is because the drift coefficient is a scaling parameter; that is, if the parameter were doubled, other parameters of the model could be doubled to produce ...
