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

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
