1 Spray coating technology for wear-resistant and anti-rust coating on cell brake disc = Công nghệ phun phủ tạo lớp chịu mài mòn và chống gỉ trên đĩa phanh ô tô / Vu Duong // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 3-9 .- 671

The article deals with gas thermal spraying technology for spraying or welding the layer of materials that are resistant to abrasion and grinding in environments with the impact of moisture. The author has proposed inexpensive materials and atmospheric plasma injection technology to lower the cost of products. This technology also has the potential to be applied in new construction or restoration of some duo parts of internal combustion engines.

2 Interval estimation of compressive strength of concrete using artificial neural network developed with Python = Dự báo theo khoảng cường độ chịu nén của bê tông sử dụng mạng nơ-ron thần kinh nhân tạo được phát triển với Python / Hoang Nhat Duc, Nguyen Quoc Lam, Pham Quang Nhat // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 10-15 .- 693

The compressive strength (CS) of concrete mixes is a crucial parameter. This paper aims to construct an artificial neural network (ANN) model for interval estimation of the CS of concrete blended with ground granulated blast furnace slag (GGBFS). The nonlinear regression based method is employed to derive the prediction intervals.

3 Current situation of design for sustainability application in visual communication design education in Vietnam = Thực trạng ứng dụng nguyên lí thiết kế bền vững trong giáo dục thiết kế truyền thông thị giác ở Việt Nam / Ngo Minh Thang, Dang Thu Phuong, Bui Mai Trinh // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 16-27 .- 004

The purpose of this study is to evaluate the current situation of applying DfS in visual communication design training in Vietnam. Besides, the study clarifies not only the current motivations, but also the existing hindrances when applying this trend at educational institutions with training courses in communication design in our country.

4 Energy and exergy analysis of a boiler : a comprehensive review = Phân tích năng lượng và dị ứng của lò hơi : bài đánh giá toàn diện / Tra Van Tung, Nguyen Thi To Nga, Tran Hai Vu, Tran Ba Quoc // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 28-38 .- 621

This review highlights the significance of energy and exergy analysis in optimizing boiler efficiency, reducing environmental impact, and promoting sustainable energy utilization. Future research should focus on advanced measurement techniques, computational modelling, and emerging technologies to enhance boiler performance.

5 The role of new generation of fashion designers = Vai trò của nhà thiết kế thời trang thế hệ mới / Bui Mai Trinh // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 44-50 .- 750

This article focuses on clarifying the role of fashion designers and assessing their ability to address the challenges in the industry. The results show that fashion designers play an important role in promoting the transformation of the fashion industry to be more sustainable; They are the pioneers in orienting and spreading sustainable fashion to consumers and the community.

6 About the model of mechanical dynamics on road motor vehicles with damping pillows installed = Về mô hình động lực học hệ máy móc trên phương tiện cơ giới đường bộ có lắp gối giảm chấn / Dao Duy Trung, Vu Duong // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 51-57 .- 621

This paper presents the results of building an oscillation analysis tool on a motor vehicle with an oscillating isolation pillow as a basis for calculating and designing electromagnetic damping pillows to reduce vibrations on this motor vehicle.

7 Fabrication of Cu2ZnSn(SxSe1-x)4 thin film solar cell using spray pyrolysis method = Chế tạo pin mặt trời màng mỏng Cu2ZnSn(SxSe1-x)4 bằng phương pháp phun nóng / Nguyen Thi Hiep, Tran Nguyen Tien, Ung Thi Dieu Thuy // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 58-63 .- 621

A kesterite Cu2ZnSn(SxSe1-x)4 (CZTSSe) thin film is fabricated on a Mo-coated glass substrate by a non-vacuum spray pyrolysis method from an aqueous precursor solution containing Cu(NO3)2, Zn(NO3)2, Sn(CH3SO3)2 and thiourea followed by sulfurization and selenization at 600°C. The fabricated CZTSSe thin film shows high crystallinity with optimal Cu-poor and Zn-rich compositions, which is confirmed by the X-ray diffraction pattern, Raman spectrum, and Energy dispersive X-ray spectroscopy results.

8 Laws of large number for random weighted sums of random variables with regularly varying tailed and application= Luật số lớn đối với tổng có trọng số ngẫu nhiên các biến ngẫu nhiên có xác suất đuôi biến đổi đều và ứng dụng / Tran Van Tam, Van Nguyen Yen Ngoc, Ho Duy Nguyen // .- 2023 .- Số 05 (60) - Tháng 10 .- P. 74-79 .- 510.76

In this paper, we study laws of large number for random weighted sums of random variables with regularly varying tailed and application. Firstly, we use the theory of slowly varying functions to establish the law of large. Then, we apply this result to estimate non parametric regression models by the k-nearest neighbors.

10 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) - Tháng 10 .- P. 80-87 .- 510

In this paper, 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.
