The method used follows a procedure and calibration method developed by Johnson et al. where 10 aliquots (20 μL volumes) are withdrawn from well-defined positions within the gradient and their densities are measured by refractive index.
To ensure consistency across reviewers, a full set of guidance notes will be produced for the data collection procedure and calibration exercises will be conducted with new members of the review team prior to any individual contribution to this review.
The setup geometry as indicated in Figures1 and5 is derived using the same procedure, settings, and calibration sample as in[33].
In this paper, a detailed mathematical modelling of a newly designed fatigue-testing rig, description of the rig, experimental set-up and procedures, and sensor calibrations are presented.
Written standard operating procedures for measures and calibration were established, and repeated training sessions for all study personnel and site visits by the team of the principal investigator and external experts were performed.
Quality control was maintained by various procedures including training and calibration of staff, the use of a standard examiner, and ongoing monitoring of interexaminer reliability and consistency with the standard examiner (Drury et al. 1996).
In a previous survey organized by our group using similar procedures of training and calibration, the overall weighted kappa value obtained by 6 examiners compared to assessments performed by a benchmark examiner was 0.78 [ 4].
The development comprises the designing process based on rotary swaging process simulations, setup assembly, and calibration procedure.
This paper describes the detectors and their associated electronics, and details are given on the data acquisition system, the triggering and calibration procedures, and the operation of the array.
The design, instrumental control and data acquisition system, initial alignment and calibration procedures, as well as the developed experimental precautions and procedures are also described in detail.
