...first looked at a dashpot and sliding-piston arrangement for the damping job. But piston O-rings introduce unpredictable friction and hysteresis that equates to jerky poppet action and erratic fuel flow. Gas-filled dampers were also considered. But they suffer compressibility effects that diminish... are particularly difficult to monitor using SPC charts, partly because they exhibit erratic behavior and noisiness. While measurement data such as critical dimensions and depths follow a Gaussian, or normal, distribution (the well-known bell-shaped curve), defect data have an asymmetrical...

...electrostatic discharge (ESD) events. Such discharges can cause microprocessors in process tools to operate unpredictably. Erratic tool behavior, in turn, can result in tool lockups, failed calibrations, and error messages, all of which lead to tool downtime and the need for operator intervention...
