An experimental study

By the aim to enhance the listening skills of EFL freshmen, an experiment was conducted using cartoons with thirty-five first-year students in an experimental group, compared to a control group, through pre-tests and post-tests. The intervention took place over five weeks during the first semester of the 2022-2023 school year, utilizing ten cartoons as research tools.

This paper develops an Artificial Neural Network (ANN) model based on 96 experimental data to forecast the dynamic modulus of asphalt concrete mixtures. This study applied the repeated KFold cross-validation technique with 10 folds on the training data set to make the simulation results more reliable and find a model with more general predictive power.

The susceptibility of the diagonal member of the Concentrically Braced Frames (CBFs) to buckling reduces the energy-dissipating capacity of the CBFs. Despite of high ultimate strength and stiffness of the CBFs as considerable advantages, its shortcoming (low dissipating energy capacity) is accounted as an important dilemma for this system.
