Correlation dropped by nearly 50% following a direction change of 90° or more, suggesting that accumulation is reduced but not abolished by large changes in movement direction.
      
The subjects reacted as quickly as possible to the direction change.
      
Further, unlike autocorrelation, which generally identifies lags close to the true lag, intra-multiplicity can erroneously identify lags anywhere in the time series and commonly results in a direction change of the correlation (i.e.

In oredrto use the tiltig-pad bearing which has optimum pivot position instead of central pivot position in reversible equipment, this paper presented the pivot position adjust installations of tilting-pad bearing according to bearing's starting with boundary friction or the liquid friction which has the station lift device. These installations can adjust pivot to optimum pivot position autimatically according to changing direction of equipment. The experimental investigation of bearing paves that these installations are reliable and valuable.
