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 aim of this study is to investigate the impact of employee relationship proneness in creating employee loyalty including attitudinal and behavioural loyalty within a Vietnamese bank context. In order to address these aims, structural equation modeling with two-steps approach was recruited with 315 valid samples. The evidence illustrated the increase in employee relationship proneness resulted in the rise of employee loyalty in both attitudinal and behavioural loyalty.

The main objective of the research is to examine internet banking service quality’s impact on customer satisfaction of Bank for Investment and Development of Vietnam (BIDV). This study is a quantitative study using the SERVQUAL model developed by Parasuraman et al. (1988) in internet banking service to define 5 dimensions of internet banking service quality as independent variables and customer satisfaction is the dependent variable. Questionnaires were also given for 320 customers and 300 surveys which were valid for analysis.

This paper is set out to explore the performance of the APT in the Vietnamese market in the context of the U.S - China trade war 2018. Testing on the listed stocks in Vietnamese stock exchanges provides a certain impact of the trade war on the asset pricing models’ effectiveness. Specifically, the trade war casts the effects on the prediction power of economic forces on the expected returns of the Vietnamese stocks. This is the first study to bring light into the investigation of the validity of the APT in the Vietnamese economy in the wake of the trade war.

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

This study focuses on experimental testing and subsequent numerical analysis of impacted and pre-loaded composite coupons and bonded composite scarf joints under varying impact conditions. A methodology will be developed for the numerical modelling of preloaded impact tests to enable capture of critical failure modes and ultimate failure. The main aim is to validate a modelling strategy that will provide accurate failure characterisation of the tested joints using numerical analysis.
