His last group of operas, composed for Rome, exhibit a deeper poetic feeling, a broad and dignified style of melody, a strong dramatic sense, especially in accompanied recitatives, a device which he himself had been the first to use as early as 1686 ( Olimpia vendicata ) and a much more modern style of orchestration, the horns appearing for the first time, and being treated with striking effect.

Paronomasia is a literary device which ' plays ' on the sound of each word for literary effect.

Investigating this effect, he created the device named after him.

Since there was no apparent practical use for such a device at the time, the patent application was most likely simply a precaution in case someone else did find a use for the so-called Edison effect.

The negative resistance of the active device cancels the ( positive ) internal loss resistance in the resonator, in effect creating a resonator with no damping, which generates spontaneous continuous oscillations at its resonant frequency.

As most applications requiring computation are now performed by small digital computers, the remaining useful application is in power sensing, which combines current sensing with voltage sensing in a single Hall effect device.

A Hall effect thruster ( HET ) is a relatively low power device that is used to propel some spacecraft, once they get into orbit or farther out into space.

In computer vision the effect is used for computer stereo vision, and there is a device called a parallax rangefinder that uses it to find range, and in some variations also altitude to a target.

The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started.

This creates a self-reinforcing effect that drives the resistance upwards, reducing the current and voltage available to the device.

When particles are measured using a low enough energy measurement device, the energy of the measurement device is not enough to cause the uncertainty principal and thus the ' observer effect ' is not a factor.

In 1904, as a result of experiments conducted on Edison effect bulbs imported from the USA, he developed a device he called an " oscillation valve " ( because it passes current in only one direction ).

Later improved vocoders use a high-pass filter to let some sibilance through from the microphone ; this ruins the device for its original speech-coding application, but it makes the " talking synthesizer " effect much more intelligible.

Electro-optic modulator ( EOM ) is an optical device in which a signal-controlled element displaying electro-optic effect is used to modulate a beam of light.

The operation of the device depends on the Faraday effect ( which in turn is produced by magneto-optic effect ), which is used in the main component, the Faraday rotator.

The device is also used to great effect in stories such as " The Three Apples " and " The Seven Viziers ".

Some cooling towers operate on this principle ; similarly the solar updraft tower is a proposed device to generate electricity based on the stack effect.

The standard ampere is most accurately realized using a watt balance, but is in practice maintained via Ohm's Law from the units of electromotive force and resistance, the volt and the ohm, since the latter two can be tied to physical phenomena that are relatively easy to reproduce, the Josephson junction and the quantum Hall effect, respectively.

Further investigation and theoretical work showed that the effect was a radiationless effect more than an internal conversion effect by use of elementary quantum mechanics and transition rate and transition probability calculations.

The quantum Hall effect was discovered by Klaus von Klitzing in 1980 when he observed the Hall conductivity to be integer multiples of a fundamental constant.

Shortly after, in 1982, Störmer and Tsui observed the fractional quantum Hall effect where the conductivity was now a rational multiple of a constant.

The quantum hall effect is another example of measurements with high magnetic fields where topological properties such as Chern-Simons angle can be measured experimentally.

In quantum field theory, the Casimir effect and the Casimir – Polder force are physical forces arising from a quantized field.

In most materials diamagnetism is a weak effect, but in a superconductor a strong quantum effect repels the magnetic field entirely, apart from a thin layer at the surface.

Although modern quantum optics tells us that there also is a semi-classical explanation of the photoelectric effect — the emission of electrons from metallic surfaces subjected to electromagnetic radiation — the photon was historically ( although not strictly necessarily ) used to explain certain observations.

In some contexts it is meaningful to speak of fractions of a charge ; for example in the charging of a capacitor, or in the fractional quantum Hall effect.

Heisenberg's principle was an attempt to provide a classical explanation of a quantum effect sometimes called non-locality.

Wavefunction collapse can be viewed as an epiphenomenon of quantum decoherence, which in turn is nothing more than an effect of the underlying local time evolution of the wavefunction of a system and all of its environment.

The quasiparticles of the fractional quantum Hall effect are also known as composite fermions, which are electrons with an even number of quantized vortices attached to them.

In a few materials, a much stronger interaction between spins arises because the change in the direction of the spin leads to a change in electrostatic repulsion between neighboring electrons, due to a particular quantum mechanical effect called the exchange interaction.

This is a direct effect of quantum mechanics: specifically, the zero point energy of the system is too high to allow freezing.

Experimental evidence for the existence of anyons exists in the fractional quantum Hall effect, a phenomenon observed in the two-dimensional electron gases that form the inversion layer of MOSFETs.

BCS theory views superconductivity as a macroscopic quantum mechanical effect.

:* Nanotechnology – rigorously, the study of materials where the effects of quantum confinement, the Gibbs – Thomson effect, or any other effect only present at the nanoscale is the defining property of the material ; but more commonly, it is the creation and study of materials whose defining structural properties are anywhere from less than a nanometer to one hundred nanometers in scale, such as molecularly engineered materials.

Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave – particle duality.

Since the complex algebra is responsible for the striking interference effect of quantum mechanics, phase of particles is therefore ultimately related to their quantum behavior.

There are many such components of acceleration present due to the effect of wind gusts, engine noise, turbulence around the vehicle, etc..

The effect is that the platform returns from an off-level position at a rapid rate until it is nearly level, at which point the platform is controlled by a proportional servo with low enough frequency response so that the noise has little effect on the leveling process.

In the presence of " communication noise " on the transmission channel ( air, in this case ), reception and decoding of content may be faulty, and thus the speech act may not achieve the desired effect.

The choice of print technology has a great effect on the cost of the printer and cost of operation, speed, quality and permanence of documents, and noise.

This reduces the effect of background noise, including clicks or pops, and also conserves the amount of physical space needed for each groove, by reducing the size of the low-frequency undulations.

The phenomenon of refraction of sound in the atmosphere has been known for centuries ; however, beginning in the early 1970s, widespread analysis of this effect came into vogue through the designing of urban highways and noise barriers to address the meteorological effects of bending of sound rays in the lower atmosphere.

The distinctive accompanying sound effect – a cyclic wheezing, groaning noise – was originally created in the BBC Radiophonic Workshop by Brian Hodgson.

This freezing reduces the radiation damage of the X-rays, as well as the noise in the Bragg peaks due to thermal motion ( the Debye-Waller effect ).

Because of the cliff effect, it can be difficult for users to tell if a particular system is right on the edge of failure, or if it can tolerate much more noise before failing.

These noise forms have the effect that the standard variance estimator does not converge when processing time error samples.

For a more thorough presentation on the Leeson effect see modern phase noise literature.

Note: The circuit noise level is usually expressed in dBrn0, signifying the reading of a circuit noise meter, or in dBa0, signifying circuit noise meter reading adjusted to represent an interfering effect under specified conditions.

An extra complication here is the effect of a reverberant room, and so noise measurement on appliances should state " at 1 m in an open field " or " at 1 m in anechoic chamber ".

A-weighted noise measurements were found to give misleading results because they did not give sufficient prominence to the 6 kHz region where the noise reduction was having greatest effect, and sometimes one piece of equipment would even measure worse than another and yet sound better, because of differing spectral content.

Though the noise level of 16-bit audio systems ( such as CD players ) is commonly quoted ( on the basis of calculations that take no account of subjective effect ) as − 96 dB relative to FS ( full scale ), the best 468-weighted results are in the region of − 68 dB relative to Alignment Level ( commonly defined as 18 dB below FS ) i. e. − 86 dB relative to FS.

The resulting effect of enhancing signal to noise ratio on the channel is called process gain.

This is an unwanted phenomenon as the previous symbols have similar effect as noise, thus making the communication less reliable.
