1 Weak two-scale convergence in L2 for a two-dimensional case = Hội tụ hai-kích thước yếu trong L2 cho một trường hợp hai chiều / Tina Mai // .- 2021 .- Số 05(48) .- P. 88-92 .- 510
Present definitions and some properties of the weak two-scale convergence (introduced by Nguetseng in 1989) for component-wise vector or matrix functions within a two-dimensional case.
2 Strong two-scale convergence for a two-dimensional case = Hội tụ hai-kích thước mạnh cho một trường hợp hai chiều / Tina Mai // .- 2021 .- Số 05(48) .- P. 121-125 .- 510
Present definitions and some properties of the classical strong two-scale convergence for component-wise vector or matrix functions in a two-dimensional case.
3 Transition nodal basis functions in p-adaptive finte element methods = Hàm nút cơ sở chuyển giao dùng trong phương pháp phần tử hữu hạn thích nghi loại p / Nguyen Trung Hieu, Phan Quoc Hung, Mai Tina, Tran Xuan Linh // .- 2021 .- Số 06(49) .- P. 35-39 .- 510
Present two different approaches to define transition nodal basis functions that can be used to allow elements of different degrees on the same mesh in p-adaptive finite element method.
4 Compare transient stress induced in in-air and in-water laser ablation using simulation method = So sánh ứng suất tức thời sinh ra trong quá trình phá hủy bằng tia laser trong không khí và trong nước bằng phương pháp mô phỏng / Nguyen Thi Phuong Thao // .- 2021 .- Số 06(49) .- P. 46-49 .- 363
Simulate the laserinduced ablation in air and in water to compare the induced stress between the two ablation regimes First, the simulation is carried out to reconstruct the experimental images obtained by photoelasticity imaging technique for in-air and in-water ablation. Then, the Von Mises Stress is elucidated from simulation for each regime. The result confirms the stress enhancement effect of water layer and showed that the stress is increased by at least two orders of magnitude if the ablation is carried in water.
5 h-adaptive refinement strategies for triangular finite element meshes = Các thuật toán làm mịn h-thích nghi cho lưới phần tử hữu hạn tam giác / Nguyen Trung Hieu // .- 2022 .- Số 05(54) .- P. 50-57 .- 510
Present two different approaches to h-adaptively refine triangular finite element messes. These two strategies are designed to keep the shape regularity of the meshes almost the same and to preserve the sparsity pattern of the resulting system of equations.
6 Ulam-Hyers-Rassias stability for a random nonlinear Volterra equation = Sự ổn định Ulam-Hyers-Rassias của phương trình tích phân Volterra ngẫu nhiên / Nguyen Tan Huy, Huynh Anh Thi // .- 2023 .- Số 05(60) .- P. 80-87 .- 510
By using the classical Banach contraction principle, we investigate and establish stability in the sense of Ulam-Hyers and Ulam-Hyers-Rassias for random nonlinear integral equations.
7 Nghiên cứu mức độ biểu hiện của một số gene kháng Magnaporthe oryzae ở lúa bằng kỹ thuật qPCR = Expression levels of rice blast resistance genes in rice-Magnaporthe oryzae interaction by qPCR / Nguyen Minh Hung, Vu Van Van // .- 2022 .- Số 6(55) .- P. 74-81 .- 570
The fungus Magnapothe oryzae causes rice blast disease, which significantly reduces the yield and quality of rice in all rice-growing regions of the world. In response to the pathogen colonization and the formation of appressorium, several families of enzymes acting on polysaccharide and lignin substrates are secreted which might facilitate infection into rice plants. In this study, we present the results on the interaction between rice and KO mutants of Magnapothe oryzae based on the analysis of expression levels of rice blast resistance genes by pPCR.
8 Two-scale convergence in Sobolev spaces for a two-dimensional case = Hội tụ two-scale trong các không gian Sobolev cho một trường hợp hai chiều / Tina Mai // .- 2023 .- Số 02 (63) - Tháng 4 .- P. 54-60 .- 510
We present some properties of the two-scale convergence in Sobolev spaces for a two-dimensional case.
9 Gabor filter based image segmentation for detecting damages on surface of reinforce concrete structures = Phát hiện các khuyết tật trên bề mặt kết cấu bê tông cốt thép sử dụng kỹ thuật phân ngưỡng ảnh dựa trên bộ lọc Gabor / Hoang Nhat Duc, Nguyen Quoc Lam, Tran Van Duc // .- 2021 .- Số 02(45) .- P. 10-15 .- 690
This study aims at developing a computer vision tool to segment images capturing surface of reinforced concrete structures. The image processing technique of Gabor filter is used with k-Means clustering algorithm and principal component analysis to automatically segment damages on concrete surface including spall, crack, bughole, and stain.
10 Optical properties of Nitrogen and Sulfur doped Graphene quantum dots = Tính chất quang của các chấm lượng tử Graphene pha tạp Nitơ và Lưu huỳnh / Le Xuan Hung, Trinh Thi Hue, Pham Thu Nga // .- 2021 .- Số 02(45) .- P. 29-34 .- 530
Present new results on the synthesis of nitrogen-doped GQDs (NGQDs) and sulfur-doped GQDs (S-GQDs) and their respective optical properties such as absorption spectra, fluorescence, and Raman spectra. The fluorescent mechanisms of GQDs, N-GQDs, and S-GQDs will also be clarified and explained.
