A finite element model using a multi-fiber approach is proposed in this paper for the analysis of reinforced concrete (RC) members using fiber-reinforced polymer (FRP) reinforcements, with a specific focus on the effect of pure torsion. The main objective of this study is to develop a numerical finite element model to predict the behavior of RC beams with FRP reinforcement under pure torsional effects.

Model for energy and exergy analysis of absorption refrigeration using waste heat from textile factory has been built. The analysis that uses different models of heat exchangers are the overall heat conductance (UA) model, and the effectiveness model. The result show that the exergy loss in the generator and absorber are the larger than condenser and evaporator.

The modulus reduction and damping curves represent the nonlinear behavior of soil under cyclic load. In the literature, those curves were produced from lab tests of soil at particular confining stresses. This study developed a set of parameters that can be used to normalize the modulus reduction and damping curves to be stress-independent.

The shear behavior of steel fiber reinforced concrete (SFRC) beams has been assessed in a large number of previous studies. However, the shear strength of corroded SFRC beams without shear reinforcement is still an unresolved topic. In this paper, the finite element models of non-corroded and corroded SFRC beams have been constructed and verified regarding load-displacement curves, crack patterns, and failure modes.

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.
