Adaptive power supply system in plot with artificially complex profile [PDF]

open access: yesE3S Web of Conferences, 2023
The paper deals with the issues of energy saving in the railway section, which has a tunnel with a double longitudinal slope, which limits the capacity of trains due to a decrease in the rated voltage by more than 10%, which negatively affects thermal ...

Tailored Gires–Tournois etalons as tunable dispersion slope compensators [PDF]

open access: yesOptics Letters, 2004
We present a novel concept of a tailored Gires-Tournois etalon structure and show that such a device is useful for the fabrication of a dispersion-slope compensator with an almost arbitrary dispersion profile and also with tunability in the dispersion slope.

Differential Confocal Optical Probes with Optimized Detection Efficiency and Pearson Correlation Coefficient Strategy Based on the Peak-Clustering Algorithm

open access: yesMicromachines, 2023
Quantifying free-form surfaces using differential confocal microscopy can be challenging, as it requires balancing accuracy and efficiency. When the axial scanning mechanism involves sloshing and the measured surface has a finite slope, traditional ...
