steam reforming integrated with oxidation of methanol was considered with numerical simulation. the parallel micro-channels with circular cross sections were used. because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. hence, the approximation of a cylindrical channel is appropriate. effect of this changing in cross section was considered and results ...

This paper investigates the accuracy of existing empirical design models and different machine learning (ML) models, known as Decision Tree (DT), Random Forest (RF), K-Nearest Neighbors (KNN), Adaptive Boosting (AdaBoost), Gradient Regression (GBRT), Extreme (XGBoost) in predicting ultimate axial load circular concrete-filled stainless steel tubular (CFSST) columns under loading. A test databas...

This paper aims to assess the structural overstrength (R), seismic behaviour factor (Q), and effective inertia (keff), of which elastic stiffness (Keff) is a function, i.e., Keff reinforced concrete (RC) cantilever columns with solid circular sections in urban bridges. The R Q factors proposed design codes have been based mainly on an empirical basis. However, some studies suggest that, case RC...
