Evaluating The Most Reliable Combination Of Non-Destructive Test Methods For Concrete Uniformity And Relative Compressive Strength. by Sibisi, Nokwanda Pearl

“…Previous research revealed that numerous factors in the concrete can largely affect the accuracy of NDT results obtained from each type of NDT test method. Hence, a more accurate approach exists in combining test results from different NDT methods to improve their reliability to estimate the compressive strength, quality and uniformity of concrete. …”

The agreement, reliability and accuracy of a subjective-rating for technique measurement in rugby union after video-based training by Wulfsohn, Jason

“…Conclusion: Whether trained or untrained, the individual should be able to produce the same results if the footage is assessed within the same viewing period (agreement) or over two separate viewings (reliability). The tool is accurate for both groups when assessing at real- time or self-selected paces, with the latter being more accurate. …”

Distortion product otoacoustic emissions: towards reliable and valid early identification and monitoring of hearing in adults receiving ototoxic medication by Petersen, Lucretia

“…Preliminary study with healthy normal hearing participants: The results of the preliminary study in healthy, normal-hearing participants indicated that the highest levels of DPOAEs were elicited with L1/L2 intensity levels of 65/65 and 65/55 dB SPL, and f2/f1 ratios of 1.18, 1.20 and 1.22, as determined by mixed model analyses (p < 0.05). These same stimulus parameters yielded the most reliable DPOAEs in both ears, as determined by intraclass correlation coefficient analysis. …”

The reliability and validity of an isiZulu speech reception Threshold test in quiet for hearing and hearing-impaired individuals in KwaZulu-Natal by Panday, Seema

“…Of the 176 participants who were selected through non-probability sampling, 100 had normal hearing and 76 had hearing loss (mild and moderate conductive, moderately severe and severe sensorineural hearing loss). Results: For the reliability study, the zSRT test was found to have high internal and external consistency (reliability) [ICC values ranged from 0.69 to 0.79]; Bland and Altman analyses showed that the isiZulu SRT test scores differed by no more than 7.5 to 8.7 dB HL between original and repeat assessments. …”
