WebI have an estimation for the magnitude of the pressures I'll be reading along the airfoil (resolution of 256 points on the x-axis, evenly spaced). Understandably, I want to place the greatest amount of sensors at the spots where there is going to be the greatest change in pressure with respect to x (i.e. the gradient of the pressure). WebTo do that, I have two functions, one being a gaussian, and one the sum of two gaussians. To test the goodness of these fits, I test the with scipy's ks-2samp test. The result of both tests are that the KS-statistic is 0.15, and the P-value is 0.476635. eagle industry taiwan https://holtprint.com
