Metallic Ti3C2Tx MXene Gas Sensors with Ultrahigh Signal-to-Noise Ratio.

open access: yesACS Nano, 2018
Achieving high sensitivity in solid-state gas sensors can allow the precise detection of chemical agents. In particular, detection of volatile organic compounds (VOCs) at the parts per billion (ppb) level is critical for the early diagnosis of diseases ...

Partition optimization for a random process realization to estimate its expected value [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2017
The paper provides an analytical proof the optimal number of partitions of a non-stationary random process realization, which is necessary for estimating its expected value when using “the estimation reproduction” method for signal processing ...

Improved signal-to-noise ratio in spectral-domain compared with time-domain optical coherence tomography.

open access: yesOptics Letters, 2003
A signal-to-noise ratio (SNR) analysis is presented for optical coherence tomography (OCT) signals in which time-domain performance is compared with that of the spectral domain.

Improved Radar Detection of Small Drones Using Doppler Signal-to-Clutter Ratio (DSCR) Detector

open access: yesDrones, 2023
The detection of drones using radar presents challenges due to their small radar cross-section (RCS) values, slow velocities, and low altitudes. Traditional signal-to-noise ratio (SNR) detectors often fail to detect weak radar signals from small drones ...
