Bad Vibrations: Machine Design Risks in Structure
The more delicate or mission-critical your application is, the more you need to keep it together – literally. The obvious risk of a poorly designed structural framing system is loss of stability(and, inevitably, structural failure). Shiny, new machine supports may inspire confidence on Day 1, but if those supports loosen with vibrat…See more on anglelock

Machine learning-based classification of quality grades for …
Upon closer examination of the samples, it was found that the presence of the two samples with zero vibration time may have contributed to the phenomenon of missing vibrations. Due to the presence of missing vibration, there were four categories in the samples, including under vibration, over vibration, normal, and 0 vibration time.
