Sentence examples for absolute frames from inspiring English sources

Pederson et al. (1998) investigated speakers of Tzeltal, a language that expressed absolute frames of reference (like "north" and "south") but lacks terms for relative frames of reference (such as "left" and "right").

Primed quantities are in the relative frame, unprimed quantities are in the absolute frame.

The flow velocity was measured by means of 2D and Stereo-PIV techniques applied in the absolute frame of reference.

Note that the velocities used in this equation are what we will later call absolute frame velocities (as opposed to relative frame velocities).

An 18-MHz linear array was used to acquire plane-wave data at absolute frame rates ≥10 kHz using a set of fixed transmission angles.

Velocity triangles are typically used to relate the flow properties and blade design parameters in the relative frame (rotating with the moving blades), to the properties in the stationary or absolute frame.

The unique absolute frame of rest with respect to which light waves had velocity c according to the prerelativistic viewpoint was often regarded, before Einstein, as being at rest relative to a hypothesized all-pervading ether.

Steered ultrasound plane waves were transmitted at an absolute frame rate of 12.5-kHz with M = 5 transmission angles spanning ±10 degrees where 0 degrees is normal to the transducer face.

In drawing these velocity diagrams it is important to note that the flow typically leaves the trailing edges of the blades at approximately the trailing edge angle in the coordinate frame attached to the blade (i.e. relative frame for the rotor, absolute frame for the stator).

Data were acquired from an image plane containing the liver and umbilical cord using a 10-kHz absolute frame rate with M = 5 transmission angles spanning ±10 degrees which yielded an effective slow-time frame rate of 2 kHz after beamforming and compounding.

The full image sequence is available as Movie 2. With the imaging plane showing the embryonic heart and umbilical vessels, data were acquired using an absolute frame rate of 20-kHz with M = 5 transmission angles spanning ±10 degrees which yielded an effective slow-time frame rate of 4 kHz after beamforming and compounding.
