Improving the Robustness of Time Difference of Arrival Estimation Based on the Energy Center of Gravity Rearrangement

Sensors, 2023
An accurate estimation of the time difference of arrival (TDOA) is crucial in localization, communication, and navigation. However, a low signal-to-noise ratio (SNR) can decrease the reliability of the TDOA estimation result.

Channel Competition and Coordination of a Dual-Channel Supply Chain under Interval Demand

Mathematics, 2023
Interval demand is becoming more common than ever before, since the variation bounds of uncertain demand are only required in practice, and they could be obtained through only a small amount of uncertain information.

Quantitative dual-channel FRET microscopy

Optics Express, 2017
Acceptor-sensitized quantitative Förster resonance energy transfer (FRET) measurement (E-FRET) is mainly impeded by donor emission crosstalk and acceptor direct excitation crosstalk. In this paper, we develop a novel E-FRET approach (Lux-E-FRET) based on linear unmixing (Lux) of the fluorescence intensity ratio between two detection channels with each ...
