Analysis Of Voice Quality on Aircraft Telephone Through Internet Telephony Gateway in Voice Over Internet Protocol

open access: yesJurnal Jaringan Telekomunikasi, 2022
Along with the development of the era, analog telephones have been replaced by IP Phones whose communication range can be wider and more flexible. Therefore, analog telephones are almost forgotten because of the limited communication range.

Predicting loss in magnetic steels under arbitrary induction waveform and with minor hysteresis loops [PDF]

open access: yes, 2004
We have studied ways of predicting power losses in soft magnetic laminations for generic time dependence of the periodic magnetic polarization J(t). We found that, whatever the frequency and the induction waveform, the loss behavior can be quantitatively

Effect of stress waveform on the rock blasting crack propagation mechanism using numerical simulation

open access: yes工程科学学报, 2022
The type, proportion, and charging method of explosives produce different stress waveforms, which greatly affect rock crack propagation. Because of the complex interaction law between waveform parameters such as the peak value, wavelength, energy, and ...

Waveform inversion of the S reflector west of Spain: fine structure of a detachment fault. [PDF]

open access: yes, 2005
The S reflection west of Iberia has been interpreted as a low-angle detachment fault separating crustal fault blocks from partially serpentinized mantle. We apply full waveform inversion to investigate the fine structure of S.
