Lifetime Assessment at High Temperatures
1998A classical power plant was generally expected to last for about 20 years or more (nuclear plant for 35–40 years). It would not normally be in operation continuously throughout the whole of this time, however, and the design was usually based on a life of 100000 hours, which is about 11 years.

Lifetime Suicide Attempts in Juvenile Assessment Center Youth
Archives of Suicide Research, 2008To describe suicide risk in youth seen at a Juvenile Assessment Center (JAC), we examined relationships among self-reported lifetime attempts and demographic, justice, and psychiatric data via logistic regression. Similar to other settings, youth reporting lifetime attempts were more likely to be older, female, not living with both parents and ...

Assessment of Lifetime Participation in Cognitively Stimulating Activities
Journal of Clinical and Experimental Neuropsychology, 2003Cognitively stimulating experience is thought to contribute to cognitive reserve. We constructed a questionnaire consisting of 25 items about frequency of participation in cognitive activities across the life span and administered it to two groups of older persons.

STATUS OF FIRST WALL LIFETIME ASSESSMENT
1993This paper describes the progress made in the various activities being carried out to determine realistic lifetimes for first wall components subjected to thermal fatigue. Testing of two medium-scale ‘prototypical’ first wall components is under way; one of these has failed after 5038 cycles and the other has accumulated 5500 cycles without visible ...

Assessment of vacuum lifetime in nL-packages
2005 7th Electronic Packaging Technology Conference, 2005Vacuum wafer bonding technology provides a number of very effective techniques to produce low-cost, hermetic sealed packages for micromachined sensors and actuators. Beside the protection of the device from outside environmental stresses, the package must also provide a cavity ambient compatible with the device performance and reliability.

STATISTICAL TESTING FOR ASSESSING LIFETIME PERFORMANCE INDEX OF THE RAYLEIGH LIFETIME PRODUCTS
Journal of the Chinese Institute of Industrial Engineers, 2008In the service (or manufacturing) industries, process capability indices (PCIs) are utilized to assess whether product quality meets the required level. And the lifetime performance index (or larger-the-better process capability index) C(subscript L) is frequently used as a means of measuring product performance, where L is the lower specification ...
