Abstract: A method of identifying pattern in a series of data, or curve, includes: first converting a curve to a permutation by relabelling the data points with their rank; second, segregating the set of all permutations into clusters of different sizes with respect to some map: permutations mapped to the same number are assigned to the same cluster. From this, one can write an alternative description of any curve, from which the original curve can be fully recovered. The length of this description is a bound on its AIC. The difference between this bound and the length of the original curve in bits, or Shannon information of the curve, is the number of bits k by which the curve can be compressed. The compression k is used to order a collection of curves in decreasing order of significance.

Abstract: A mechanism for mounting a soil leveling device to the mounting arm of a leveling attachment operates in either a fixed setting or a floating setting. The mechanism includes a rearwardly extending carrier arm which carries the soil leveling device at its distal end. The carrier arm is pivotably connected at its proximal end to the mounting arm of the leveling attachment for upward and downward movement. A connecting link is mounted to the mounting arm and a spring assembly extends between the link and the carrier arm. The connecting link is selectively operable in either a fixed setting or a released, floating setting. When the connecting link is in the fixed setting, the spring assembly biases the carrier arm and the leveling device with a downward force. When the connecting link is in the floating setting, the leveling device can move across a soil surface free of a downward bias from the spring assembly.
