Threshold amplitude

This spectrum will be compared with standard one built by the manufacturer. In this paper, the standard spectrum of well-known elevator manufacturers such as Kone, Schindler etc. will be introduce for reference of Vietnamese elevator manufacturers.

In this paper, we analytically investigated the possibility of parametric resonance of acoustic and optical phonons. We obtained a general dispersion equation for parametric amplification and transformation of phonons.

Based on the importance of the short range order effect of the plasmas OCP, which is expressed through the damped oscillations of the pair correlation function g(r), we carry out elaborate examinations of the location rmax as well as of the amplitude gmax of its first maximum for various values of the screening parameter and put forward for the first time the analytical formulae for these data. The linear variation of the screening potential for some interionic distance can be therefore explained thoroughly by considering the relation between this first maximum and the screening potential.

Speech signals have a very wide dynamic range: Harsh “oh” and “b” type sounds have a large amplitude, whereas softer sounds such as “sh” have small amplitudes. If a uniform quantization scheme were used then although the loud sounds would be represented adequately the quieter sounds may fall below the threshold of the LSB and therefore be quantized to zero and the information lost. Therefore non-linear quantizers are used such that the quantization level at low input levels is much smaller than for higher level signals.
