introduction: fractures of the orbital floor, which are caused by various mechanisms, result in the herniation of periorbital tissue into the paranasal sinuses and its subsequent complications. early diagnosis using various techniques and reduction of fractures are necessary to preserve ocular function and esthetic. use of an endoscope has been associated with some advantages, including a decre...

Reinforced steel is one of the most important building materials in civil engineering and improving intelligence reinforcement can greatly promote intelligent development construction industry. This research addressed problems slow speed poor accuracy manually extracting rebar processing information, which leads to a low degree intelligence. Firstly, based on digital image technology, preproces...

Clad rebars of four different base materials (20MnSiV, 35# steel, 45# and 55# steel) were successfully produced by a vacuum hot rolling process. A metallographic optical microscope (OM), electron backscatter diffractometer (EBSD), probe micro-analyzer (EPMA), salt spray corrosion chamber used to investigate the clad contour, properties, composite interface microstructure all rebars. The results...
