PUPMSI (version 0.1.0)

OswinMSI: Oswin Moisture Sorption Isotherm

Description

An empirical model developed through a series of mathematical equations that consists in a series expansion for sigmoidal curves.

Usage

OswinMSI(WaterAct, AdsorpM, DesorpM)

Arguments

WaterAct

the numerical value of Water Activity, which ranges from 0 to 1.

AdsorpM

the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1.

DesorpM

the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1.

Value

the nonlinear regression, parameters, and graphical visualization for the Oswin Moisture Sorption Isotherm model.
