VIBRATION EXPERIMENT OF COAL SHEARER CUTTING UNIT GEARBOX HOUSING IN OBLIQUE CUTTING

open access: yesJixie qiangdu, 2020
Oblique cutting is a working condition in fully mechanized mining whose main task is making it possible for long wall shearer to cut the coal seam,and it is a harsh working condition since the shearer is forced to be bent.

Comparison of an oblique single cut rotation osteotomy with a novel 3D computer-assisted oblique double cut alignment approach [PDF]

open access: yesScientific Reports, 2021
AbstractAn oblique double-cut rotation osteotomy (ODCRO) enables correcting a complex bone deformation by aligning, in 3D, the distal, middle and proximal bone segments with a target bone, without intersegmental gaps. We propose virtual preoperative planning of an ODCRO.
