Four common free radical photoinitiators were evaluated for use in thick photopolymerizations illuminated with a medium-pressure 200W mercury–xenon arc lamp and a high-intensity 400nm light-emitting diode (LED) lamp. For each photoinitiator/lamp combination, the spatial and temporal evolution of the photoinitiation rate profile was analyzed by solving the set of differential equations that govern the light intensity gradient and initiator concentration gradient for polychromatic illumination.

Paper for the Adhesive and Sealant Council’s (ASC) 2000 conference in Las Vegas, NV.
The concept of reliability-centered maintenance has been around since the 1930’s. Maintenance has evolved from the “fix it when it is broken” mode of operation to a philosophy of maintenance where technology and expectations meet in an effort to improve operation, reduce operating costs and increase equipment longevity. Monitoring has also progressed from the processing of sensor information installed on a piece of machinery, to developing custom inspection, test and measurement systems that provide extremely useful diagnostic information on manufacturing processes themselves. This trend is taking reliability-centered maintenance to the next level and requiring more complex system-level development efforts.
