Our main contribution is an algorithm to identify all paths that might become critical during the specified lifetime.
To assure that this design still works correctly during the specified lifetime, the circuit is monitored periodically and countermeasures are taken if the circuit degrades too much.
The concept of two-dimensional strength is proposed to incorporate the electric driving voltage and the working temperature of the piezoelectric actuators at a specified lifetime.
For the construction, design and operation of nuclear components and systems the appropriate technical codes and standards provide detailed analysis procedures which guarantee a reliable behaviour of the structural components throughout the specified lifetime.
Using the specified lifetime functions of new cars, I firstly estimated the survival rate of the used cars that are newly purchased at year 0 and survive at year t after re-registration at year τ, φ u t, τ), using Eq. (3).
Of course, this idea could not be adopted without amending the Constitution, which specifies lifetime tenure.
The end of study was based upon the 6-day ENL manufacturer-specified lifetime, after which the patient made a final visit.
In addition, the probability for fluorescent photon generation following absorption can be controlled through definition of the quantum yield, ϕ, a feature not available in the pre-existing GEANT4 class, and the time profile of fluorescence emission can be designated as a delta function or exponential distribution with a specified lifetime, t.
Using the two parameters, I can specify the lifetime distributions for cars newly registered during 1993 2014 and for used cars re-registered during the same period.
Manufacturers specify that the lifetimes of joint endoprostheses, i. e. the time between first operation and the first reoperation, is 15 years and above.
