For small w, the height should be proportional to w, for w ->
infinity, the height should rise to a limit asymptotically.
- Hence we take F(x) such that
- F(0) = 0 , F'(0) = 1, and F(infty) = 1
+ Hence we take F (x) such that
+ F (0) = 0 , F' (0) = 1, and F (infty) = 1
and use
- h = h_infinity * F(x * r_0 / h_infinity)
+ h = h_infinity * F (x * r_0 / h_infinity)
Examples:
- * F(x) = 2/pi * atan (pi x/2)
+ * F (x) = 2/pi * atan (pi x/2)
- * F(x) 1/alpha * x^alpha / (1 + x^alpha)
+ * F (x) 1/alpha * x^alpha / (1 + x^alpha)
* (etc.)

Although this might seem cand_idates to SCM-ify, it is not all clear
- which parameters (ie. h_inf, r_0, F(.)) should be candidates for
+ which parameters (ie. h_inf, r_0, F (.)) should be candidates for
this. At present h_inf and r_0 come from paper settings, but we did
no experiments for determining the best combinations of F, h_inf and
r_0.
