# yeadon python module ([email protected]) # Measurement input template. # Lines beginning with pound (#) are comment lines. # There are 95 distance measurements, consisting of lengths, # perimeters, widths, and # depths. # # For details about how the measurements are to be taken, consult the # journal article Yeadon 1989-ii or the documentation of this python package. # # CONVERSION FACTOR to convert measurements INTO meters # (set to 1 if measurements are in meters, 0.001 if measurements are in mm, # 0.0254 if measurements are in inches) measurementconversionfactor : .01 # # DENSITY CORRECTION # the mass of the human can be set to a measured mass (by scaling the densities # used) if the totalmass field below is set to a a value greater than 0. # Alternatively, the next line can be deleted from the input file. totalmass: 84.273 ############################################################################## # TORSO # Ls0 hip joint centre # Ls1 umbilicus # Ls2 lowest front rib # Ls3 nipple # Ls4 shoulder joint centre # Ls5 acromion # Ls6 beneath nose # Ls7 above ear # Ls8 top of head # # lengths to levels 1 through 5 are measured from Ls0, the hip centre: Ls1L: 14.8 Ls2L: 21.6 Ls3L: 35.7 Ls4L: 50.2 Ls5L: 55.7 # lengths to levels 6 through 8 are measured from Ls5, the acromion: Ls6L: 13.9 Ls7L: 17.4 Ls8L: 28.9 # # stadium parameters: Ls0p: 102.1 Ls1p: 90.9 Ls2p: 85.8 Ls3p: 96.5 Ls5p: 41 Ls6p: 53.5 Ls7p: 58.1 # # stadium widths: # width nor depth are measured for Ls5, acromion, because its shape is set by # estimates from Ls4, shoulder joint centre.
