This study presents the application of six single algorithm-based models of artificial intelligence, such as artificial neural network (ANN), support vector machine (SVM), classification and regression trees (CART), linear regression (LR), general linear model (GENLIN), and automatic Chisquared interaction detection (CHAID) to predict the residual flexural capacity of corroded RC structures.

Structural and spatial patterns of tree species in forests are important indicators to explain which underlying mechanisms or processes regulating forest structure. In this article, techniques of spatial point pattern analysis were used to characterize structural and spatial patterns of two secondary rain forest stands in Cuc phuong National park, Vietnam.
