7). When a receiver detects a path that is indeed the combination of several neighboring paths, due to fast variations of the phases of the original path, the amplitude of the detected path experiences Rayleigh or Rician fading and the TOA of the detected path obviously is something very ...

As a demonstration to prove the feasibility of the proposed method, measurements were performed during two representative electrochemical processes driven by near-infrared (NIR) continuous wave (CW) laser irradiation: electro-oxidation and electro-detection. Stable and reproducible correlations between the...
of GNSS observation stations increases, their application fields are becoming increasingly extensive. GNSS is not only used in PNT, but also can use its surface reflection signal for remote sensing. GNSS satellites continuously broadcast radio signals to Earth, and some of them are reflected off ...
The significant reduction in multiple scattering going from 1.3 to 4 μm therefore represents the transition from the domain of strong directional Mie scattering with a short photon mean-free path to the domain of weaker uniform Rayleigh scattering having a long photon mean-free path, compared ...
[44,45]. The jet shape is defined by the nozzle setup, through which the liquid is pumped to the interaction point. In addition, it is also possible to generate a droplet stream by using piezoelectric actuators, which generate standing waves through which the growing Plateau-Rayleigh ...
When distributed measurements are performed at 100 points with 10 times averaging, a repetition rate of 100 Hz is verified by tracking a mechanical wave propagating along the fibre. Some drawbacks of this ultrahigh-speed configuration, including the reduced measurement accuracy, lowered spatial ...
