For a Gaussian filter, Equation 11.3 may be rewritten as: (11.4)F(p)=f(S,p)=(h⊗S)(p) where S is the signal, h is the filter function and ⊗ denotes the convolution operator. For the visualization of vasculature, the skeleton corresponds to the signal. The selected filter ...
If the crystallite size is known a priori , a standard deviation鈥搘idth scaling function can be calculated; also some insight can be gained into the nature of the curve describing the diffraction profile. A computer program in Fortran IV has been written which fits Gaussian curve forms to ...
a polynomial fit can always fit a curve , it's just a matter to find the minimal order (even by trial and error) look for polyfit J. Alex Lee on 15 Sep 2022 At first glance this looks to me like a superposition of a Gaussian and a line...or otherwise a line plus some kind...
Following improvements by Lo and Wilson (1999), Chang et al (1998) derive a modified Reynolds’ equation for Gaussian roughness as (4.12)ddxϕxht312ηdpvdx=u¯dhtdx+Δu2σdϕsdx where ht is the mean film thickness, Δu is the sliding speed and ϕx and ϕs are pressure and ...
Once you've summarized each curve as a single value, compare those values using a paired t test. For example, below are the results of a binding study to determine receptor number (Bmax). The experiment was performed three times with control and treated cells side-by-side. Each value is ...

7 for Austria. The distribution density is well approximated by the Gaussian curve with an average value of 10 and a standard deviation of 132. The differences from the Gaussian curve are characterized by the skewness of 1.1 and kurtosis equal to 2. Similar conclusions can be made for the ...
