Analysis of coal drawing law and parameter research in shallow buried double hard and extra-thick coal seam

open access: yesGong-kuang zidonghua, 2022
The coal resources in Xinjiang are shallowly buried, the coal seam is thick, resulting in poor top coal caving and drawing. And the roof is overhanging in a large area, which makes it impossible to achieve safe and efficient top coal mining.

Training compliance control yields improvements in drawing as a function of Beery scores. [PDF]

open access: yesPLoS ONE, 2014
Many children have difficulty producing movements well enough to improve in sensori-motor learning. Previously, we developed a training method that supports active movement generation to allow improvement at a 3D tracing task requiring good compliance ...

From the Crossing Numbers of K5 + Pn and K5 + Cn to the Crossing Numbers of Wm + Sn and Wm + Wn

open access: yesAxioms
The crossing number of a graph is a significant measure that indicates the complexity of the graph and the difficulty of visualizing it. In this paper, we examine the crossing numbers of join products involving the complete graph K5 with discrete graphs,
