In the following, we provide a mathematical investigation of the Higuchi method [1], an algorithm which aims at approximating the box-counting dimension of the graph Γ of a bounded real valued function f: [0, 1] → R arising from a (measured) time series. For numerous applications, the graphs of these functions … WebAug 26, 2008 · The present work evaluates the two-layer technique on the heat affected zone (HAZ) of AISI 4140 steel welded with different heat input levels between the first and second layer. The weld heat input levels selected by the Higuchi test were 5/5, 5/10, and 15/5 kJ/cm. The evaluation of the refining and/or tempering of the coarsened grain HAZ of the …
