An analog synthesizer generates its sound by electricity passing through capacitors, resisters and other electronic components. The electricity flows through continuously like water, and the sound it produces is a continuous wave. On a digital synthesizer the sound is constructed incrementally by stringing together hundreds of digitized samples or "snapshots" of a sound to simulate a waveform.  3, record 1, English, - digital%20synthesizer

The jigging cycle for coal may be represented as a sine wave... in which water velocity is plotted against time. Starting from rest, the water commences to rise through the closely packed bed of coal with increasing velocity. Dilation of this bed begins with the loosening of the uppermost stratum.(In jigging coal it is possible to apply water so as to toss the whole bed solidly upward and then to allow it to open out upward and downward, but this is not feasible with heavy minerals.) As the water column attains a rising velocity of 100 mm./sec., the upper part of the coal bed opens and begins to teeter. Velocity continues to increase, and layer after layer opens until the whole bed is dilated and teetering. Then, as the pulsion stroke passes its peak, the velocity of the water lessens and the suction stroke begins.  5, record 13, English, - dilation

Electromagnetic radiation passes through the first half-silvered mirror(left-hand side). The radiation can then either be transmitted through or reflected by the second mirror.

Subatomic particles have various properties and are affected by certain forces that exhibit symmetry. An important property that gives rise to a conservation law is parity. In quantum mechanics all elementary particles and atoms may be described in terms of a wave equation. If this wave equation remains identical after simultaneous reflection of all spatial coordinates of the particle through the origin of the coordinate system, then it is said to have even parity. If such simultaneous reflection results in a wave equation that differs from the original wave equation only in sign, then the particle is said to have odd parity. The overall parity of a collection of particles, such as a molecule, is found to be unchanged with time during physical processes and reactions; this fact is expressed as the law of conservation of parity.  2, record 26, English, - law%20of%20conservation%20of%20parity

A particularly sensitive and accurate type of hygrometer has been developed in recent years by the Instrument Division of the U. S. Weather Bureau. The device, known as the infrared hygrometer, employs a beam of infrared light projected through the air to a photo-electric detector. Two separate wave lengths of light are used; one is absorbed by water vapor and the other passes through undiminished. The ratio of the infrared light transmitted by the different wave lengths is a direct indication of the amount of water vapor in the light path.  1, record 33, English, - infrared%20hygrometer

In the homogeneous equilibrium model (HEM) one assumes that the velocity, temperature and pressure between the phases or components are equal.  1, record 34, English, - homogeneous%20equilibrium%20model

Record number: 34, Textual support number: 1 OBS

This assumption is based on the belief that differences in these three potential variables(and chemical potential if chemical reactions are considered) will promote momentum, energy, and mass transfer between the phases rapidly enough so that equilibrium is reached. For example, when one phase is finely dispersed in another phase generating large interfacial area, under certain circumstances this assumption can be made; e. g., bubbly flow of air in water or steam in water at high pressures. The resulting equations resemble those for a pseudo-fluid with mixture properties and an equation of state which links the phases to obtain these mixture thermodynamic properties. Whenever the HEM model is used it is advisable to check the validity of the equilibrium assumptions by using more accurate theoretical models for comparison. For example, rapid acceleration or pressure changes cannot be always accurately modelled with the HEM model; i. e., discharge of flashing vapor-liquid mixtures, or shock wave propagation through a multiphase medium. This is especially true when the pressure change is large when compared to the ambient pressure, or any of the driving potentials are large relative to their reference values.  1, record 34, English, - homogeneous%20equilibrium%20model

Les écoulements à direction privilégiée peuvent soit être considérés comme monodimensionnels, soit conduire à des équations simplifiées en ne considérant que les termes prédominants.

En écoulement à direction privilégiée (vertical ascendant), les deux phases étant en équilibre thermodynamique et mécanique, le modèle homogène à l'équilibre (HEM) se révèle satisfaisant et particulièrement utile.

Various methods have been proposed to implement a digital-to-analog converter(DAC). One such method is to create a pulse train whose average value is equal to the magnitude of the digital input and then average the pulse train by passing it through a low-pass filter. Conventionally, pulse wave modulators(PWM) are used to create the pulse train from a digital input signal. However, the quality of the analog signal that results from the filtered pulse train may contain considerable noise unless an expensive low-pass filter is constructed.  1, record 38, English, - pulse%20wave%20modulator

Wave Motion. A wave is, in general, a disturbance which moves through a medium. It carries energy from one location to another without transporting the material of the medium. Examples of mechanical waves include water waves, waves on a string, and sound waves.  3, record 49, English, - wave%20motion

Record number: 49, Textual support number: 2 CONT

For example, sound is a form of wave motion; wind is not. Wave motion can occur in a vacuum (electromagnetic waves), in gases (sound waves), in liquid (hydrodynamic waves) in solids (vibration waves) and in plasmas (soliton waves).  4, record 49, English, - wave%20motion
