We show that by modifying the doping, we can tune the frequency of emission.
The sound directivity, frequency of emission and intensity of warning sound systems will guarantee their efficiency and limited noise impact.
Even though ROM did not vary in frequency of emission as a function of the number of players involved, it was reciprocated more often during dyadic encounters, in which the players had the highest probability to engage in a face-to-face interaction.
Attempts to describe the origin of the emission and absorption lines (i.e., the frequencies of emission and absorption) of even the simplest atom, hydrogen, in the framework of classical mechanics and electromagnetism failed miserably.
Since no wave magnetic field measurements were made, information concerning the mode of propagation of the detected waves must be deduced from the spectral and temporal characteristics of the emissions, the relationship of the frequency of the emission to characteristic frequencies of the plasma, and comparisons with similar emissions studied at the Earth.
In the plasma emission theory, the frequency drift of emission features can be explained by (i) non-thermal electron beams, which are common in type III bursts (e.g., Suzuki and Dulk, 1985), or (ii) whistler-mode waves, thought to be the origin of fiber bursts (e.g., Kuijpers, 1975).
In the second phase, the frequency of acoustics emission counts appears to gradually increase, and the peak count of acoustics emission gradually increases.
where E is the photon energy, h is the Planck constant (6.63 × 10−34 J·s), γ is the frequency of the emission light, c is the light velocity (3×108 m/s), and λ is the wavelength of the emission light.
In the third phase, the frequency of acoustic emission counts appears very high.
In the triaxial compression test, the frequency of acoustic emission counts appears very high in the first stage.
where Ip is the photocurrent generated by p-FET, e is the electron charge, h is the Planck constant, and ν is the photon frequency of fluorescence emission.
