The aim of this work is to perform a detailed analysis the cracks paths obtained in fretting fatigue tests with cylindrical contact but taking into account presence an unavoidable (due device’s stiffness) small oscillatory rolling. In order obtain crack surfaces were measured confocal microscope after tests. Besides, area and surface initiation location by means optical microscope. measurements...

This paper proposes a test cost prediction model which estimates the cost of IC testing in a manufacturing environment. The model predicts chip testing cost and quality of test using a set of circuit manufacturing parameters. The objective is to use these circuit parameters which are available at the early stage of the design cycle to determine and optimize manufacturing test cost.

For the one-sample problem, a two-stage rank test is derived which realizes a required power against a given local alternative, for all sufficiently smooth underlying distributions. This is achieved using asymptotic expansions resulting in a precision of order m-~, where m is the size of the first sample. The size of the second sample is derived through a number of estimators of e.g. integrated...
