Optimization of process lability in logistics systems
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 3 Số SI3 - Trang SI29-SI35 - 2020
Csaba Imre Hencz, Tamás Hartványi
The management and effective operation of enterprise systems – depending on ever-changing environmental impacts – can only be achieved by an appropriate information management practice. Today, in the corporate environment, an astonishing amount of data (often unstructured) is generated. The efficient processing of these data is by no means straightforward and unambiguous, and thus presents signifi...... hiện toàn bộ
Preparation of activated red mud and its application for removal of hydrogen sulfide in air
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 2 Số SI2 - Trang SI40-SI45 - 2019
Tran Dinh Vi, Nguyen Nhat Huy, Le Truong Anh Huy, Pham Dan Thanh, Bui Khanh Le, Le Nguyen Dang Khoa, Le Thi Kieu Thi, Vo Thi Thanh Thuy, Pham Hong Hai, Lam Pham Thanh Hien, Doan Quoc Vinh
Red mud is a highly alkaline solid waste from the Bayer process for aluminum production. Red mud reservoirs are usually considered as a potential environmental risk. The treatment of red mud is costly due to the lack of an effective and economical treatment technology. On the other hand, the main components of red mud are Fe2O3, Al2O3, SiO2, and Na2O, which could be employed as a promising precurs...... hiện toàn bộ

Robustness control for nonlinear systems based on homogeneous prescribed sliding mode control
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 4 Số 2 - Trang 1019-1035 - 2021
PHU XUAN DO, HUNG QUOC NGUYEN
This paper presents a new homogeneous control using dual sliding mode control, and robustness control using linear matrix inequality (LMI) constraints. The controller is applied for the severe disturbance. A sliding surface function, which relates to an exponential function and itself t-norm, is applied to save the energy consumption of the control system. The constraints related LMI are proposed ...... hiện toàn bộ
Application of mathematical programming for optimal programming of Vietnamese fishing fleet
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 2 Số 4 - Trang 213-222 - 2020
Tran Gia Thai
The Vietnamese fishing fleet has been developing spontaneously without programming and control. It has bring about detrimental effect on the operate of fishing fleet, especially with a serious impact on the resources. The programming of the fishing fleet, that has been set up by the our fisheries authority, but so far there is no satisfactory solution for the complexity of the problem. In this pap...... hiện toàn bộ

With USV model with two hull, control and propulsion systems, both of which are specifically designed to allow the vehicel to perform this task flexibly, omnidirectional and maneuverable...... hiện toàn bộ
Use of wheat flour and sugarcane bagasse in the production of fiber-rich biscuit: Effects of sugarcane bagasse ratio on the product quality
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số 4 - Trang 1679-1685 - 2023
Nguyen Anh Kiet Vo, Thị Thu Trà Trần, Thị Nguyên Nguyễn, Nữ Minh Nguyệt Tôn, Hiền Thảo Lê, Văn Việt Mẫn Lê
Nowadays, sugarcane is used as main material to manufacture crystal sucrose and packaged sugarcane juice. The sucrose production generates sugarcane bagasse with sugarcane peel while the sugarcane juice production releases sugarcane bagasse without its peel. There have been many reports on the use of sugarcane bagasse with peel to produce various value-added products. Nevertheless, the application...... hiện toàn bộ

Screening for in vitro inhibiting Nrf2 of some Vietnamese medicinal plants
Tạp chí Kỹ thuật và Công nghệ Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 6 Số 3 - Trang In press - 2023
Hien Minh Nguyen, Han Nguyen Thien Le, Nhi Thi Yen Nguyen, Hoa Thanh Vo, Thi Tan Pham, Chia-Hung Yen
Nuclear factor erythroid 2–related factor 2 (Nrf2) is vital in regulating cellular defenses against oxidative or environmental aggressors. Some studies reveal that increasing Nrf2 activity affects chemotherapy drug resistance in cancer; thus, Nrf2 has become an attractive target in cancer therapeutics research. Our study screened the effects of 52 methanol extracts from different parts of 24 medic...... hiện toàn bộ
