Due to their precision, compact size, and high torque transfer, Rotate vector (RV) reducers are becoming more popular in industrial robots.However, repetitive operations and varying speed conditions mean that these components are prone to mechanical failure.Therefore, it is important to develop effective health monitoring (HM) strategies.Traditiona
Optimization of fast tool servo diamond turning for enhancing geometrical accuracy and surface quality of freeform optics
Fast tool servo (FTS) in ultra-precision diamond turning is an efficient technique for high-precision fabrication of freeform optics.However, the currently adopted constant scheme for control point sampling takes no account of the shape variation of the desired surface, which might lose some micro features and result in low form accuracy and non-un
Second-order texton feature extraction and pattern recognition of building polygon cluster using CNN network
The cluster patterns of features in map space represent a comprehensive reflection of individual feature geometric attributes and their spatial adjacency relationships.These patterns also embody spatial cognition results under the Gestalt principle.Describing non-linear spatial cluster patterns as effective regular structures is one of the fundamen
Biochar boosts tropical but not temperate crop yields
Applying biochar to soil is thought to have multiple benefits, from helping mitigate climate change [ 1 , 2 ], to managing waste [ 3 ] to conserving soil [ 4 ].Biochar is also widely assumed to boost crop yield [ 5 , 6 ], but there is controversy regarding the extent and cause of any yield benefit [ 7 ].Here we use a global-scale meta-analysis to i
