Bilge keels are passive stability systems. On commercial shipping the bilge keel is the form of a strake, or small keel or blister, running along much of the length of the hull. They are typically fitted one on each side, low down on the side of the hull, so as not to increase the draft of the vessel.
Intensity is a measure of the strength of shaking experienced in an earthquake. The Modified Mercalli Scale represents the local effect or damage caused by an earthquake; the intensity reported at different points generally decreases away from the earthquake epicenter.
Intensity is measured in the speed of a runner or the height or distance of the jump. Sometimes intensity is estimated or inferred from the results of the behavior like measuring the distance of travel of the baseball off the bat or the speed of the baseball thrown.aseball (and other sports) fans seem to be obsessed with measuring behavior of all types. They measure the frequency of many things including the number of pitches thrown, number of strikes, balls, singles, doubles, home runs, wins, and loses.
