In the command window of MATLAB, write the code as follows: x=[10 20 30 40 50 60 70]; sum(x) The MATLAB output will display the result as follows, 280. Snakes: active contour models. Graphical User Interfaces (GUIs) are implemented in order to import EBSD results, and to represent and quantify grain boundary slip resistance. We find that it is possible to use the magnetization measurements to determine the average grain size even if the SEM image analysis allows extracting more information about the grain size distribution. The parameters calculated for these analyses include: 1. The grain width and length of screened lines ranged from 1. 4 Discriminant Analysis 9. As the grain size decreases, more free volume is generated resulting in lattice mismatch. A quasi grain size distribution is calculated following Fehr's line-sampling method (VAW, 1987). Three samples of each biomass were analyzed, and the average value of the mass retained in each sieve of the three samples was taken.
