Modeling the Microwave Transmissivity of Row Crops

Applied Computational Electromagnetics Society, 2021
We develop a method to model the microwave transmissivity of row crops that explicitly accounts for their periodic nature as well as multiple scattering. We hypothesize that this method could eventually be used to improve satellite retrieval of soil moisture and vegetation optical depth in agricultural regions. The method is characterized by unit cells

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Labor carrier experiments in row crops

California Agriculture, 1966
The six-man labor carrier designed and tested by the University of California demonstrates a basic concept that can be adapted to the needs of individual growers and produced at a low cost per man—offering a useful tool to aid in attracting and keeping ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Theoretical and experimental substantiation of the design parameters for the working body of a row cultivator [PDF]

E3S Web of Conferences, 2019
The authors of the article propose the design of a row cultivator, equipped with combined working bodies, which makes it possible to carry out inter-row weed control in one pass with full cultivation of the protective zones of grown crops.
