WebThe mean overall glucose concentrations were 0.11±0.02 mg/dL in saliva and 86.3±0.8 mg/dL in plasma, and these did not differ significantly by body–weight groups. By regression analysis, the plasma concentration equaled 13.5 times the saliva concentration, with a threshold level of 84.8 mg/dL. WebboostThreshold: number. Set the point threshold for when a series should enter boost mode. Setting it to e.g. 2000 will cause the series to enter boost mode when there are 2000 or more points in the series. To disable boosting on the series, set the boostThreshold to 0. Setting it to 1 will force boosting.
WebSep 17, 2024 · The value provided by the Hough transform for each line indicates the number of positive pixels on each line. All possible lines are parameterized by polar coordinates, i.e. radius r and angle 0 (see Fig. 3). The Hough transform supplies a matrix whose entries are assigned possible values of radius r and angle 0.
