Deep encoder and decoder for time-domain speech separation

open access: yesMechanical Engineering Journal, 2023
The previous research of speech separation has significantly improved separation performance based on the time-domain method: encoder, separator, and decoder. Most research has focused on revising the architecture of the separator.

The Validity of Ultra-Short-Term Heart Rate Variability during Cycling Exercise

open access: yesSensors, 2023
Ultra-short-term heart rate variability (HRV) has been validated in the resting state, but its validity during exercise is unclear. This study aimed to examine the validity in ultra-short-term HRV during exercise considering the different exercise ...

A Time-Domain Numerical Method for Multi-Conductor Coaxial Lines Using the Exact Retarded Potential Integral Equations

open access: yesIEEE Access, 2021
We present a time-domain numerical method for calculating the current propagating through coaxial lines including the radiation effect. In previous studies of transmission lines using the retarded potential integral equations (RPIE), the so-called thin ...

Unidimensional Time Domain Quantum Optics

open access: yes, 2019
Choosing the right first quantization basis in quantum optics is critical for the interpretation of experimental results. The usual frequency basis is, for instance, inappropriate for short, subcycle waveforms.

Some Applications of a Field Programmable Gate Array Based Time-Domain Spectrometer for NMR Relaxation and NMR Cryoporometry

open access: yesApplied Sciences, 2020
NMR Relaxation (NMRR) is an extremely useful quantitative technique for material science, particularly for studying polymers and porous materials. NMR Cryoporometry (NMRC) is a powerful technique for the measurement of pore-size distributions and total ...

Time domain optical sensing

open access: yes1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 1999
A chirped optical supercontinuum is used to map absorption spectra into temporal waveforms. Time-domain spectral measurement of acetylene is demonstrated using a modelocked fibre laser as the source of broadband radiation and a sampling oscilloscope for spectral measurement.
