Abstract At present, there is a problem, which inconvenient for people to record structure failure data, in some experimental process of special equipment. Focusing on the trigger method high speed photography recording component strength experiment equipment, and choosing feature vibration situation that specimen failure, we design two schemes, are integration switch basing velocity voltage co...

Several factors have been incriminated in the etiologies of critical incidents: shortages in organizing rules, anesthesia technique, patient environment, human factor, team work and communication. This is the third follow up report describing our performance during the last five years (2003-2008). The possible incriminating causes were identified with the objective of avoiding such eventualitie...

Reliability engineering focuses on the ability of physical equipment to function without failure [...]

Anti friction bearings in process pumps, by design, frequently utilize oil sump lubrication technology. For many years, it was an accepted condition that the lubricating oil used in oil sump bearing lubrication needed to be changed on a regular basis to prevent high levels of contamination that can lead to premature bearing failure, contributing to equipment downtime. Often, the indicators used...
