The paper sheds light on the adaptation of a literary work reaching the pinnacle of Vietnamese medieval written literature in the context of the regional and Vietnam's particular traditional culture through decoding the creative process of Nguyen Du's The Tale of Kieu - a symbol of Vietnamese national culture. The paper shows how a literary work has become a national literary peak and the image of The Tale of Kieu becomes a symbol of national consciousness, the spirit of cultural nationalization.

In this paper, the effect of continuous carbon fibers (CCF) on the stiffness of 3D printed frames is investigated. Fused deposition modelling (FDM) technology is employed to build three typical frames with 15% of CCF and 85% poliamide 12 which is combined 10% short carbon fibers (PA12-CF) for compress testing.

This paper applies the homotopy analysis method to study nonlinear free vibrations. The paper has used the homotopy analysis method to find analytical solutions of a nonlinear two-degree-of-freedom system. Analytical results have found the natural oscillation frequencies, the displacement formula of the system are approximately calculated at the 10th order.

In this paper, we propose an effective AMC using deep learning (DL) for flexible and adaptive OFDM-based optical networks. The proposed DL-based AMC is able to classify four typical modulation schemes such as binary phase-shift keying (BPSK), quadrature PSK (QPSK), 8-PSK, and 16- quadrature amplitude modulation (QAM) in dynamic network conditions.
