Finds the 3 parameters —
Fickian contribution fraction, x,
Fickian and relaxation parameters,
kF, and kR —
in the "swelling" (expansion) of superabsorbent polymers.
Some of these polymers can absorb water up to ~1 000 times
their dry weight (1 kg / g), as in [Rosa et al., 2002].
This PHP front-end calls a Python master that
uses Fortran 90 and 'gnuplot'. The main files are:
(a) P-SupAPolymer.php
(this one);
(b) Superabsorbent.php,
'action' manager;
(c) superabsorbent.py,
Python hub importing the following module and calling 'gnuplot'; and
(d) user module from
modSuperabsorbent.f90,
created through 'f2py3'.
This is also a template (or paradigm) for many other
Engineering (or better, STEM) problems.
Advantage is taken from: PHP,
for the web page; Python, as "glue"; Fortran,
for numerical segment; and 'gnuplot', for plotting.
Draws graphs with the experimental points and
the calculated points from regression.
