The spatial resolution of these data is one arcsecond (30 m along the equator) with a nominal planimetric accuracy of ±20 m and an elevation accuracy of ±16 m, and the WGS84 coordinate system and EGM96 elevation datum (orthometric) are adopted. The study area and DEM data are shown ...
During the braking process, due to the application of braking torque, the contact point of the wheel to the rail tends to slide to the right, and the load of the wheel causes the wheel to be tightly pressed onto the rail surface, forming a slight deformation. This deformation causes a sm...
4.14, if all failure criteria are active, the resulting failure envelope is the inner intersection of each individual criterion failure envelope, as denoted by the open circle symbols. Similarly, Fig. 4.15 shows the failure envelopes for the 6-ply quasi-isotropic laminate considered previously. ...

Although the number of publications with an RRI focus is steadily growing, the research on the topic is still relatively limited. Existing research tends to expound the concepts of RRI in a top-down manner to formulate standardized principles or frameworks guiding innovation towards producing the ‘...
