Sentence examples for elevation threshold from inspiring English sources
Using the azimuth-dependent elevation threshold (ADET) mask typically gives 22 28% more useful data than using a fixed-elevation threshold at the sites studied in this paper.
To investigate the impact of the solar elevation threshold, when switching the boundary between different phases of day, we varied the elevation threshold and tested the performance of the proposed approach for recognition of perceptually similar colours.
We investigated the optimum number of periods in a year and the solar elevation threshold that results the best performance.
The Mahalanobis distance boundary settings were applied in three phases of the day (morning, midday and evening) with elevation threshold of 20°.
The maximum elevation threshold is also subjective, but in this case, it was based on mountain pine beetle biology (Safranyik and Carroll 2006).
A better solution, albeit one requiring a nonstandard analysis of the GNSS adjustment residuals, would be to reconstruct the satellite-receiver slant delays and, after selecting only those above a given elevation threshold, average their zenith projection [as in Sato et al. (2013)].
Some studies suggest that sensitivity can reach 80% or even 100% (see Table 1) leveraging regional-specific ST elevation thresholds or computer-generated features including the QRS complex and the T wave.
Conventional methods, such as the optimal-elevation threshold method, the optimal-curvature threshold method, and the D8 method, cannot achieve satisfactory performance under these conditions.
Typically, conservative fixed-elevation thresholds of 20 40° are used to filter out signals from low elevation angles, but this leads to the exclusion of a significant quantity of useable data.
In these investigations multipath effects and noise that contaminate the scintillation measurements are largely filtered by applying an elevation angle threshold.
On inspection, only the condition with the higher-contrast mask and a different pattern appears to show a clear elevation of threshold.
