This software is licensed to: Carl Kim CPT name: CPT--3 <br />TRANSITION LAYER DETECTION ALGORITHM REPORT <br />Summary Details & Plots <br />Short description <br />The software will delete data when the cone is in transition from either clay to sand or vise-versa. To do this the software <br />requires a range of 4 values over which the transition will be defined (typically somewhere between 1.80 < 4 < 3.0) and a rate <br />of change of Ic. Transitions typically occur when the rate of change of Ic is fast (i.e. delta 4 is small). <br />The SBTn plot below, displays in red the detected transition layers based on the parameters listed below the graphs. <br />SBTn Index Norm.
