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Along with the development of the era, analog telephones have been replaced by IP Phones whose communication range can be wider and more flexible.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

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.

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 ...

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.

Duration of Purkinje cell complex spikes increases with their firing frequency

open access: yesFrontiers in Cellular Neuroscience, 2015
Climbing fiber (CF) triggered complex spikes (CS) are massive depolarization bursts in the cerebellar Purkinje cell, showing several high frequency spikelet components (±600 Hz). Since its early observations, the CS is known to vary in shape.

CardioLabelNet: An uncertainty estimation using fuzzy for abnormalities detection in ECG

open access: yesHealth Care Science, 2023
Electrocardiography (ECG) abnormalities are evaluated through several automatic detection methods. Primarily, real‐world ECG data are digital signals those are stored in the form of images in hospitals.
