It is

**shown**that the simulation 1) represents a slow drift motion in reality. These figures show that by neglecting time varying of Ma or Du the maxima tend to be overestimated. The simulation 2) is an overestimate in Figs. 27 and 31.Page 166

The results are

**shown**in figure 7 . They indicate that an averaging period of half an hour or more gives good estimates for Mo. A one half hour initial averaging period is therefore acceptable . The data sampling and averaging procedure ...### What people are saying - Write a review
