By placing a liquid particle counter in-line with an ICP-OES system it is possible to analyze wear metals and particles in lubricant samples in one run. This approach streamlines the monitoring of in-service lubricants and meets the ASTM D5185 standard. Such analyses are critical for heavy machinery maintenance.

High-precision statistics on desertification of grassland features are an important part of ecosystem research. In this study, a vis-NIR hyperspectral remote sensing system for unmanned aerial vehicles (UAVs) was used to analyze the type and presence of vegetation and soil of typical desertified grassland in Inner Mongolia using a deep belief network and 2D and 3D convolutional neural networks.
