Natural Frequencies of Composite Cylindrical Helical Springs,ea fraction is used as weights. The impedance method is then applied to determine the natural frequencies of the spring. The results show the existence of two sets of resonance frequencies, the frequencies of slow axial waves and those of rapid rotational waves. They correspond to the fundamental an

Principal Directions-Based Pivot Placemente been introduced in the literature. In this paper, we propose a pivot placement strategy which exploits the natural data orientation in order to select space points which achieve a good alignment with the whole data to be indexed. Comparison with existing methods substantiates the effectiveness of the approach.
