Summary: A new thickness measurement model was developed by adding an auxiliary transparent film in the initial position of the dispersion field, overcoming the limitations of the conventional self-supporting film thickness measurement model. Experimental results showed significant improvements in stability and measurement accuracy with the proposed method.

Summary: We developed a mobile application called ARTreeWatch, based on augmented reality (AR), for measuring tree height and diameter at breast height using an Android smartphone. Compared to traditional ground surveys, ARTreeWatch showed high accuracy in measuring tree structural parameters and saved half the labor costs and time.

Summary: NASA's GEDI mission aims to provide high-resolution measurements of forest structure and topography, but current geolocation accuracy limits its applications. Researchers developed a method using lidar data to evaluate and mitigate geolocation errors, finding large errors in the first release of GEDI data but improved accuracy in the second release. This approach provides a short-term solution for improved calibration and validation of GEDI and has the potential to generate biomass products using in-situ data.

Summary: In this article, the idea of using machine learning methods for sea surface height retrieval based on GNSS-R is proposed. Two widely-used methods, PCA-SVR and CNN, are verified and compared based on observation data. The results show that the machine learning models achieve accurate SSH retrieval with good predictive performance.

Summary: This systematic review examines the methods and accuracy of symphysis fundal height (SFH) measurement for estimating gestational age (GA) in low- and middle-income countries. The findings suggest that SFH measurement is inaccurate and should not be used for GA dating. Improving access to quality ultrasound early in pregnancy is crucial for improving gestational age assessment in LMIC.

Summary: The study presents a method for using a depth camera sensor to acquire wave elevation fields and assesses the test uncertainty. The depth camera module of an Azure Kinect is calibrated using marker arrays to establish a mapping function between the pixel-wise and physical position. The depth camera is aligned using the built-in inertial measurement unit to be perpendicular to the calm water surface. The systematic and random standard uncertainties are evaluated through calibration and repeated tests, and the wave height measurement results are compared with other gauges.
