... behavior of a thin-walled box-girder bridge exposed to high-speed train loads using regression analysis. Design/methodology/approach The high-speed train is mathematically represented by a system with 38 degrees of freedom (DOF), while the sub-track system uses China’s Railway Track System slab track...

... the fabrication of welded joint under different parameters Friction stir welding Mechanical properties Fuzzy logic model Regression analysis Aluminium alloys are highly sought after due to their unique and appealing qualities, which include a high strength-to-weight ratio, sufficient toughness...

... in ANSYS. Regression analysis was performed to obtain the relation between density and thermal conductivity. Finally, the quality of the predicted regression equations was assessed using root mean square error (RMSE), mean absolute error (MAE), integral absolute error (IAE) and normal efficiency (NE...

... Regression analysis Factor of safety Underground quarries Parametric study Resistance of pillar Underground quarries constitute a serious risk in the context of geological hazards. Localized instabilities at the level of quarries can also lead to consequential collapses at the overlaying terrain...

.... According to the method of uniform design, 8 groups of test matching scheme of calcareous coal gangue mixture were designed. The experiments were conducted on calcareous coal gangue mixtures in various matching proportions. The experimental results are analyzed by regression analysis model. The regression...
