compact

1. (Or "finite", "isolated") In domain theory, an element d of a cpo D is compact if and only if, for any chain S, a subset of D,

d <= lub S => there exists s in S such that d <= s.

I.e. you always reach d (or better) after a finite number of steps up the chain.

Compaction of the soil by tractors was achieved by driving the tractor once across the length of the plot at speed of 5 km/h.
Tyres of different sizes were used in this experiment, and their area of contact with the soil is reported to allow comparison of the compaction caused by each tractor.
2001) that soil water is an important factor in soil compaction.
The water itself acts as a binding agent in increasing soil compaction slightly, through its tensile strength; for example, increasing soil water content in the topsoil (0-100 mm), with no external load, from AD to 50% FC, FC, and Sat increased cone index values from 1.
The experimental design for in-plane permeability consisted of five compaction ratio levels for mats prepared with 0.
