(aerospace engineering)
An airfoil feature in which either the thickness or the chord length or both decrease from the root to the tip.
(electricity)
Continuous or gradual change in electrical properties with mechanical position such as rotation or length; for example, continuous change of cross section of a waveguide, or distribution of resistance in a potentiometer.

taper

A gradual diminution of thickness in an elongated object, as in a spire.

The tooth preparations with different tapers and chamfer shoulder, together with the complete cast crowns were designed (Fig.
Now, according to a report in New Scientist, Vera Smolyaninova of Towson University in Baltimore, Maryland, and colleagues have used a convex lens to create the tapered waveguide and trap a rainbow of light.
There was no significant difference (p>0.05) in the peak HR between the two tapers. However, peak HR on day 9 of each taper was significantly lower than on days 1 and 3.
While the 22/15 mm taper connectors were retained, the International Standard used a simplified system that did not use the sequential system of tapers and added a coaxial 15 mm socket taper to the 22 mm conical taper of the machine outlets and breathing-system connectors which connected to equipment such as catheter mounts or 15 mm endotracheal connectors.
David Matthew, CX-7 vehicle line manager, describes the front as looking like "a big, angry RX-8." On the side, there's a higher beltline than is found on the typical SUV and the roofline tapers back, starting with the A-pillar, which is angled back 65.6[degrees].
On the street frontage the site is 3.2m wide, but tapers down along its length to just under a metre.
Last, but certainly not least, is the ability of the 330F to cut heavy tapers. A heavy taper is very important in the process of cutting complex extrusion tools.
``But there are two sets of taper relief, and the gain tapers away much more quickly for business assets than for assets seen as passive investments.''
The most commonly used methods for creating this radial "clamping" force are interference fits, axially preloaded tapers, and radially preloaded slotted hubs.
Another way to change the performance of a line is by shortening or lengthening its front and back tapers or shortening or lengthening its "head," the total length from the back taper to the tip (see illustration).
The SPM concept is amazingly simple - drop the batch discharged from an internal mixer into a wide mouthed hopper which tapers to a casing featuring dual tapered screws, where the screws in turn convey stock material to a transition area.
An alternative means for creating tapers in the core without the external diameter of the fiber changing is to heat the fiber locally for some period of time so that the core diffuses from its original location out into the fiber.when this happens, that is, when the index of refraction of the core is decreased and the size is increased, the V-number stays roughly the same.
