Closing the loop: autonomous experiments enabled by machine-learning-based online data analysis in synchrotron beamline environments

Journal of Synchrotron Radiation, 2023
Recently, there has been significant interest in applying machine-learning (ML) techniques to the automated analysis of X-ray scattering experiments, due to the increasing speed and size at which datasets are generated.

Comparison and Synergy of BPSK and BOC Modulations in GNSS Reflectometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Signals from global navigation satellite systems (GNSSs) have been advocated as opportunities for remote sensing of the Earth. In the multi-GNSS era, signals from different constellation, at different frequency, and under different modulation are ...

Investigating Adsorption of Cellulose Nanocrystals at Air–Liquid and Substrate–Liquid Interfaces after pH Manipulation

Advanced Materials Interfaces, 2023
Coatings of anisotropic nanoparticles such as cellulose nanocrystals (CNCs) can provide tuneable physicochemical surface properties to a substrate such as modifying wettability. These coatings are often formed using dip coating, with CNCs enriched at the

Using microwave refraction to determine local inhomogeneities of a rotating plasma

Nukleonika, 2023
To determine the local inhomogeneities of a rotating plasma, the method based on microwave refraction was used. The method is based on spectral and correlation analysis of the reflected signals from the rotating plasma layer at normal and inclined ...

Application of GNSS Interferometric Reflectometry for the Estimation of Lake Ice Thickness

Remote Sensing, 2020
Lake ice thickness is a sensitive indicator of climate change largely through its dependency on near-surface air temperature and on-ice snow mass (depth and density). Monitoring of the seasonal variations and trends in ice thickness is also important for
