Finally, the study proves that, on the formed tubes, obtaining small calibration radii and obtaining high values of hardness are conflicting objectives.
The powder was filled in a small calibration chamber and in-line NIR spectra of calibration samples were collected from moving material while mimicking the powder flow dynamics in a typical continuous mixer.
Furthermore, in order to improve the calibration efficiency, a novel method of corner detection based on region of interest (ROI) is also proposed to quickly detect the chessboard corner in the image of a small calibration target.
This study aimed to assess whether intraocular pressure (IOP) measured by Goldmann applanation tonometers with known small calibration errors could be adjusted to reflect true IOP to allow continued clinical use.
In this work, we focused on a calibration factor obtained from a planar acquisition of a small calibration source imaged in air due to its relative simplicity.
Figure 5 SOS and STFD-MUSIC: standard deviation versus SNR for small calibration errors (SPR = 30 dB). Figure 6 SOS and STFD-MUSIC: standard deviation versus the number of sensors for low SNR (= -10 dB) and small calibration errors (SPR = 30 dB). Figure 7 SOS and STFD-MUSIC: standard deviation versus number of sensors for high SNR (= 10 dB) and small calibration errors (SPR = 30 dB).
In all simulations, we limit our discussion to small calibration errors and consider the signal to perturbation ratio (SPR) for the values 30, 35, and 40 dB.
Based on these results and observations, recommendations and suggestions can be made when a planar acquisition of an in-air small calibration source is the basis for determining the calibration factor.
As expected from data model (4) and Equation (28), it is observed in this figure that the presence of small calibration errors (SPR = 30 dB) have no significant effect on both methods and all occurs as if there were only the presence of the additive noise.
Even a small calibration error causes significant degradation of the reconstructions based on absolute data.
Pilot testing with a relatively small calibration sample is used to estimate the conditional probabilities that subjects of particular literacy levels will answer a particular question correctly.
