1Thickness planer — A thickness planer (also known in the UK and Australia as a thicknesser or in North America as a planer) is a woodworking machine which is used to create boards that are of an even thickness throughout their length and flat on the upper… …
2Boundary-layer thickness — This page describes some parameters used to measure the properties of boundary layers. Consider a stationary body with a turbulent flow moving around it, like the semi infinite flat plate with air flowing over the top of the plate. At the solid… …
3Audio tape length and thickness — Since the widespread adoption of reel to reel audio tape recording in the 1950s, audio tapes and tape cassettes have been available in many formats. This article describes the length, tape thickness and playing times of some of the most common… …
4Intima-media thickness — (IMT), also called intimal medial thickness, is a measurement of the thickness of artery walls, usually by external ultrasound, occasionally by internal, invasive ultrasound catheters, see IVUS, to both detect the presence and to track the… …
5Knot thickness — In knot theory, each link and knot can have an assigned knot thickness. Each realization of a link or knot has a thickness assigned to it. The thickness tau; of a link allows us to introduce a scale with respect to which we can then define the… …
6Finite thickness — In formal language theory, a class of languages mathcal L has finite thickness if for every string s , there are only finite consistent languages in mathcal L. This condition was introduced by Dana Angluin in connection with learning, as a… …
7Thin-film thickness monitor — Thin film thickness monitors, deposition rate controllers, and so on, are a family of instruments used in high and ultra high vacuum systems. They can measure the thickness of a thin film, not only after it has been made, but while it is still… …
8Momentum thickness — In aeronautics and viscous fluid theory, the boundary layer thickness ({delta}) is the distance from a fixed boundary wall where zero flow is considered to occur, and beyond {delta} the fluid is considered to move at a constant velocity. This… …
9Ultrasonic thickness gauge — measuring instrument for the non destructive investigation of the materials thickness using the ultrasonic waves.First ultrasonic thickness gauge in the world was constructed by the Polish engineer Werner Sobek from Katowice, in year 1967. The… …
10Optical thickness — Optical thickness, also called optical depth, is the depth of a material or medium in which the intensity of light (or other radiation) of a given frequency is reduced by a factor of 1/e. In rough terms 1/3 of the light is absorbed within one… …
