..., there is a tendency, in the case of the centrifuge, for this fact to be considered of relative insignificance. Alternatively machines may be designed with full regard to the stresses likely to arise in service but, in many cases, they are not subjected to any form of inspection during their service life...

... and model parameters have some uncertainty in real-world structures. To this day (2020), structural design codes are deterministically based, with the uncertainties accounted for by using conservatisms such as safety factors, design factors, and so on to cover a realistic range of variation. Given the level...

.... This continual variation approach was applied to the striping problem. Rather than operating the induction furnace at one frequency, the furnace control circuit was designed to continuously vary the frequency. This modification in operating conditions completely eliminated the striping problem. Case #3...
