The phrase "absolute gradient" is correct and usable in written English.
It can be used in contexts related to mathematics, physics, or engineering, particularly when discussing the concept of a gradient that is not relative to any other point or reference.
Example: "To find the absolute gradient of the function, we need to calculate the derivative at the specified point."
Alternatives: "total gradient" or "overall gradient".
With the gradient method, the fatigue stress is adjusted with the relative or absolute gradient of the fatigue stress itself.
R 2, calculate the gradient in x and y directions and estimate the absolute gradient magnitude ?
Typically it is used to find the approximate absolute gradient magnitude at each point in an input grayscale image.
Sobel operator is also less expensive in terms of computations because it computes absolute gradient magnitude, which is an integer value.
The noisy measurements of the gradient are assumed to be, where is an independent zero-mean Gaussian random variable (and thus fulfils the conditions of a martingale difference noise) whose variance depends on and is percent of the absolute gradient value.
To do so, we apply the Sobel operator to find the absolute gradient magnitude at each pixel of the given image (Iin) and then use a threshold on the values to approximate the regions (pixels) corresponding to edges (I E ) and non-edges (I NE ).
Monte Carlo simulations and experimental data from laminar flames are used to verify and validate the models used to predict noise propagation for the measurements of the absolute gradients, squared gradients, and scalar dissipation rates.
Similarly, we found no evidence that absolute gradients (where we disregarded the signs) were related to the degree of common orientation.
Thus, the smaller absolute gradients in pStat3 seen in conditions without LIF may be due to the down-regulation of pathway components due to decreased responsiveness to the pathway.
While fractional gradients appear to be significantly poorer candidates for guidance cues than are VEGF concentrations, absolute gradients seem to be as effective as VEGF concentrations (Additional file 1, section S3; Figs. S3.2, S3.3).
Absolute gradients greatly extend the range of isoforms for which matrix-bound VEGF in the HSPG-binding-only model displays isoform monotonicity (Additional file 1, Figure S3.2Biii), however in the matrix-sequestered VEGF degradation model, it seems to show little variation with respect to changes in MMP activity, indicating weak HSPG/MMP antagonism (Additional file 1, Figure S3.3).
