Slurry flowmetering using correlation techniques
… Africa. An alternative flowmeter based on cross-correlation techniques is thus proposed. Random signals generated by the flowing fluid are measured at two points a known distance apart in the direction of the flow. Assuming that this distance is not "too" large, the downstream signal is a …

Fluid flow measurement using correlation techniques
The applicability of the temperature cross correlation method to measurement of flow under steady and pulsating flow conditions is investigated. The factors to be considered in applying this technique to different flow systems are discussed and its advantages over the conventional techniques are …

A Study of Ion Concentration Fluctuations in Turbulent Diffusion Flames using Correlation Techniques
… by the probe was analysed to determine its auto correlation function. The ionisation field was generated by seeding the flame with acetylene and other metal salt solutions preselected on the basis of their Damkohler number values in the flame. Studies have also been conducted to map the flame …

The Relation of Attachment, Adjustment and Narcissism to Masculine Gender Role Conflict
… Hypotheses were tested using canonical correlation techniques. Results indicated that healthy attachment was related to low masculine gender role conflict; however, unhealthy attachment was not related to high masculine gender role conflict. In terms of narcissism, higher amounts of …

HRVA - a velocity analysis technique for seismic data
… the time sampling interval, as are the existing correlation techniques. The technique liberally exploits the inexistence of significant energy in the higher frequency harmonies of seismic data, resulting in a considerable time saving. The technique is illustrated with West Texas seismic data. The …
