Methods and systems for thermodynamic evolution. The method decomposes the shape by introducing one or more splicing graphs on the shape. In one embodiment, the segmenting elements are located between selected channels, limiting the size of the different segments. The joint structure has an enlarged-diameter end formed at an end of the pipe, an internal sleeve movably inserted into the enlarged-diameter end of the pipe, and a hollow locking bolt movably fitted over the pipe at a position around the enlarged-diameter end. In one or more arrangements, an identity risk score may be determined based on whether information entered by the subscriber can be confirmed and a level of confidence with which the information is confirmed.
