Typically, a new logfile is created periodically, and the old logfile is renamed by appending a "1" to the name. Each time a new log file is started, the numbers in the file names of old logfiles are increased by one, so the files "rotate" through the numbers (thus the name "log rotation").
Cycloramic is an iOS and Windows Phone application that makes the Apple iPhone and Compatible Windows Phones rotate 360 degrees without user intervention. It switches the phone's vibrator at a specific (undisclosed) frequency to make the phone spin around its vertical axis and track the rotation angle using the gyroscope, compass and accelerometer while taking panoramic images.
Video of the propeller of a Bombardier Q400 taken with a digital camera showing the wagon-wheel effect Video of a spinning, patterned paper disc. At a certain speed the sets of spokes appear to slow and rotate in opposite directions.
Centrifugal force is one of several so-called pseudo-forces (also known as inertial forces), so named because, unlike real forces, they do not originate in interactions with other bodies situated in the environment of the particle upon which they act. Instead, centrifugal force originates in the rotation of the frame of reference within which ...
The D- and L- prefixes describe the molecule as a whole, as do the (+) and (−) prefixes for optical rotation. In contrast, the ( R )- and ( S )- prefixes from the Cahn–Ingold–Prelog priority rules characterize the absolute configuration of each specific chiral stereocenter with the molecule, rather than a property of the molecule as a whole.
For orbits that do not have an eccentricity close to zero, the rotation rate tends to become locked with the orbital speed when the body is at periapsis, which is the point of strongest tidal interaction between the two objects. If the orbiting object has a companion, this third body can cause the rotation rate of the parent object to vary in ...
The reciprocal of the rotational shear is the lap time, i.e. the time it takes for the equator to do a full lap more than the poles. The relative differential rotation rate is the ratio of the rotational shear to the rotation rate at the equator: α = Δ Ω Ω 0 {\displaystyle \alpha ={\frac {\Delta \Omega }{\Omega _{0}}}}
Associativity of a binary operation means that performing a tree rotation on it does not change the final result. The Day–Stout–Warren algorithm balances an unbalanced BST. Tamari lattice, a partially ordered set in which the elements can be defined as binary trees and the ordering between elements is defined by tree rotation.
