Abstract : This report considered the mean number of crossings of an arbitrary curve, in a given time T, by a nonstationary normal process. A formula was obtained for this and sufficient conditions for its validity given. These conditions concern the behavior of the covariance function of the normal process. Incidental results include sufficient conditions for continuity of a normal (nonstationary) process x(t), and also for x(t) to satisfy a Holder condition. (Author)
