In the latter group, descriptors are created through an empirically verifiable procedure and are based on observable learner behavior, including 'the data-based or data-driven approach,'empiricallyly derived, binary-choice, boundary definition scales,'scalingng descriptors' (Fulcher 2003, p. 92).
In order to determine whether this result is due to our choice of boundary conditions we implemented periodic boundary conditions.
Thus, we find non-linear deformations of Einstein solutions which, after taking a suitable near horizon limit and imposing our particular choice of boundary conditions, turn out to be precisely characterised by solutions to the incompressible Navier-Stokes equation.
Since none of the results in the paper actually relies on the boundaries of the spatial region under consideration, the effect of this choice of boundary condition is minimal.
An important issue is the choice of boundary conditions (cases when either ( {R}_1^{in} ) or ( {R}_1^{out} ) equals 0 or 100): contrary to previous studies, the boundary conditions are fixed to be the perfect mixing case (Eq. 2).
However, a good predictability could be achieved when appropriate choice of boundary and inflow conditions is made.
The shape of the optimal folding is shown to be greatly influenced by the choice of boundary condition.
As an application, we show that the integrated density of states is independent of the choice of boundary conditions.
The stark choice between boundary and bridge creates a middle space, an in-between that holds the possibility of exchanges and encounters.
The paper discusses a number of modelling and implementation aspects including model geometry and computational domain, choice of boundary conditions, and discretisation schemes.
