Wide variation in the way clinical services are provided to similar patients for similar visit types results in highly variable costs but similar clinical outcomes. Objective: To identify optimal ...

Common cause vs. special cause variation, aren’t they the same thing? At first glance, you’d be allowed to think so. However, as with any part of the production cycle, there is a reason for these two ...

The economics for random variation are changing, particularly at advanced nodes and in complex packaging schemes. Random variation always will exist in semiconductor manufacturing processes, but much ...

As technology nodes shrink to 90 nanometers and below, chips become much more difficult to manufacture. In-die process variations increase substantially at 90 nm — even more at 65 nm. If these effects ...
