The incubation time, inct , required for an appearance of the BFe2 iron boride was obtained by a linear regression from the experimental data taken from Campos-Silva et al. [6].

Balenda et al. first used simple springs to represent the foundation flexibility supporting asymmetric multi-storey buildings[2].
