An analytical model is developed for accelerated performance degradation tests. The performance degradations of products at a specified exposure time are assumed to follow a normal distribution. It is assumed that the relationship between the location parameter of normal distribution and the...

Effective Curie-temperatures measured in Fe monolayer strips agree reasonably with computer simulations of two-dimensional Ising model strips. The simulations confirm the domain structure seen already by Albano et al. (1989).
