In literature:

Lockley interpreted the term to mean sine waves, rounded at top and trough.
"Operation Terror" by William Fitzgerald Jenkins
Nobody hardly uses anything but sine waves for communication, but I got to make this gadget turn out a freak wave-type by guess and golly.
"The Machine That Saved The World" by William Fitzgerald Jenkins
I drew some sketches of overlapping sine waves for her to explain what I thought was going on.

The machine scans the patterns of the mind, translates what it sees into charts and sine waves.

The new line of UPS systems from Middle Atlantic features Pure Sine Wave technology, integration with AV control systems, and a sliding rackrail mount for single-person UPS mounting capability.
The UL/cUL distinctions also coincide with the first American theatrical-venue use of sine wave technology at the Overture Center for the Arts, in Madison, WI.
To serve wideband analog-to-digital-converter (ADC) and direct-digital-synthesis (DDS) architectures, the VFTX210 temperature-compensated crystal oscillator (TCXO) provides a sine-wave output frequency to 1.0 GHz with jitter under 0.3 ps.
It is a true sine wave unit and therefore an excellent inverter charger .
Upgraded features include a real-time measurement mode, an enhanced impulse response mode, support for multichannel input devices, and triggered swept sine wave functionality for traditional laboratory quality control measurements .
Chances are that if you ask the typical electrical engineer to generate a 120-Hz sine wave, delay a signal by 300 µsec, or create a 10-µsec pulse once every second, most engineers would not think of using a microcontroller.
From the beginning of the power quality era, designers of disturbance analyzer equipment have understood that sine wave distortions are essentially unique.
When necessary, data center computer synchronization is done on a digital signal level rather than on the power source's 60 Hz sine wave.
The two-tone-terminator (T3) line of diode mixers offers excellent suppression of IMD while providing high performance levels with both sine-wave and square-wave local-oscillator signals through 12 GHz.

In science:

Vref is the amplitude of the test signal without perturbation and ∆Vtest is the maximal error Vtest - Vref. Without encoding the sine wave stimulus the rejection of a perturbation that has its power concentrated around the test frequency (not filtered by the sensor or the test filter) is equal to 0dB.

In the basic superposition scheme presented in , the stimulus is a sine wave signal (see Figure 1).

Let us consider a sheet deforming as a sine-wave propagating to the right (Fig. 3).

The sensor sensitivity is measured by transmitting single cycle gated sine wave signals with different central frequencies from 5 kHz to 100 kHz.

We choose a sine wave that propagates towards the right through a periodic box.
Conservative, special-relativistic smoothed particle hydrodynamics
We use equal mass particles in this test, constant pressure throughout the box is instantiated as in the sine wave problem above and we impose again a constant initial velocity of v0 = 0.997.

Second, we expand the Shapiro delay for small-eccentricity orbits as a function of orbital harmonics, i.e., sine and cosine waves with frequencies that are integer multiples of the orbital frequency.

Identity (64) means that the triangular sine and rectangular cosine waves capture temporal symmetries of periodic processes regardless specifics of individual vibrating systems.
