Abstract Background Two-dimensional (2D) medical visualization techniques are often insufficient for displaying complex, three-dimensional (3D) anatomical structures.Moreover, the visualization of medical data on a 2D screen during surgery is undesirable, because it requires a surgeon to continuously switch focus.This switching focus problem also r
In complex mountainous areas where earthquakes are frequent, landslide hazards pose a significant threat to human life and property due to their high degree of concealment, complex development mechanism, and abrupt nature.In view of the problems of the existing landslide hazard susceptibility evaluation model, such as poor effectiveness and inaccur

The application of cold-formed steel channel sections for portal frames becomes more popular for industrial and residential purposes.Experimental tests showed that such structures with long-span up to 20 m can be achieved when knee brace joints are included.In this paper, the influence of knee brace configuration on the optimum design of long-span
To solve the problems of dynamic model parameter perturbation and external disturbances during the operation of the ball screw meta-action unit, an adaptive sliding mode control method based on disturbance compensation and inertia identification is proposed in this paper.First, a model of the ball screw meta-action unit is established and the dynam
