Waveforms from amplitudes [PDF]

open access: yesPhysical Review D, 2022
We show how to compute classical wave observables using quantum scattering amplitudes. We discuss observables both with incoming and with outgoing waves. The required classical limits are naturally described by coherent states of massless bosons.

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Along with the development of the era, analog telephones have been replaced by IP Phones whose communication range can be wider and more flexible.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.

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 ...

Discrete Fourier Transform Windowing Techniques for Cerebral Physiological Research in Neural Injury: A Practical Demonstration

open access: yesNeurotrauma Reports, 2023
To optimally assess oscillatory phenomena within physiological variables, spectral domain transforms are used. A discrete Fourier transform (DFT) is one of the most common methods used to attain this spectral change.

Size Effect on the Acoustic Emission Behavior of Textile-Reinforced Cement Composites

open access: yesApplied Sciences, 2021
Acoustic emission (AE) is applied for the structural health evaluation of materials. It commonly uses piezoelectric sensors to detect elastic waves coming from energy releases within the material.

Prediction of vertical bearing capacity of waveform micropile [PDF]

open access: yes, 2019
This study proposes a predictive equation for bearing capacity considering the behaviour characteristics of a waveform micropile that can enhance the bearing capacity of a conventional micropile.

Stochastic Uncertainty in a Dam-Break Experiment with Varying Gate Speeds

open access: yesJournal of Marine Science and Engineering, 2021
Uncertainties inherent in gate-opening speeds are rarely studied in dam-break flow experiments due to the laborious experimental procedures required. For the stochastic analysis of these mechanisms, this study involved 290 flow tests performed in a dam ...

Accelerating gravitational wave parameter estimation with multi-band template interpolation [PDF]

open access: yes, 2017
Parameter estimation on gravitational wave signals from compact binary coalescence (CBC) requires the evaluation of computationally intensive waveform models, typically the bottleneck in the analysis.
