In the original publication of the article, the set of Equations 1 was wrongly typeset.

The set of Equations 1 should read as given below

$$\begin{aligned}P_{i}^{x} &= (F_{i} - C) \cdot (n \times h) \\ P_{i}^{y} &= (F_{i} - C) \cdot h \\ P_{i}^{z} &= (F_{i} - C) \cdot n \\ \end{aligned}$$

The original publication of the article has been updated to reflect the change.
