In fractal geometry, the Higuchi dimension (or Higuchi fractal dimension (HFD)) is an approximate value for the box-counting dimension of the graph of a real-valued function or time series. This value is obtained via an algorithmic approximation so one also talks about the Higuchi method. It has many applications in science and engineering and has been applied to subjects like characterizing primary waves in seismograms, clinical neurophysiology and analyzing changes i… WebHiguchi model The first example of a mathematical model aimed to describe drug release from a matrix system was proposed by Huguchi in 1961 (31).

However, the earliest equation expressing dissolution rate in a quantitative manner was proposed by Noyes and Whitney as:- dC / dt = k (C s - C t ) where dC / dt is the rate of change in concentration with respect to time, and k is the rate constant.
