Xây dựng và điều khiển mô hình con lắc ngược quay cho phòng thí nghiệm
Số 49 - 2018
Con lắc ngược quay là một mô hình quen thuộc và cơ bản trong lý thuyết điều khiển tự động. Tuy nhiên, giá tiền một mô hình là rất cao, không phù hợp điều kiện trang bị phòng thí nghiệm còn hạn chế ở Việt Nam. Các mô hình được tự chế tạo hiện nay thì không đáp ứng được thông số mô hình, dẫn tới việc áp dụng các giải thuật phụ thuộc vào mô hình không được thiết kế thành công.

Design and Optimization of a Large-Stroke Compliant Constant-Torque Mechanism
Số 68 - 2022
Compliant constant-torque mechanism (CTM) can produce an output torque that does not change within a prescribed input rotation range. This stability is maintained regardless of complicated sensorized control systems. Owing to the monolithic nature of the compliant mechanism, the device is more compact, lightweight, and portable, which is favorable to human joint rehabilitative devices or mobil...... hiện toàn bộ

Differences between Chemical Reaction Kinetics and Adsorption Kinetics: Fundamentals and Discussion
Số 70B - 2022
Adsorption kinetics is an essential part in adsorption studies. The pseudo-first-order (PFO) and pseudo-second-order (PSO) models are frequently used to model the experimental dataset of time-dependent adsorption. The differential equations (based on reaction rate and rate law) of the PFO and PSO models are similar to those of chemical reactions (i.e., first and second order-kinetic reactions). Th...... hiện toàn bộ

Study on Designing and Manufacturing the Freeze Drying System with the Process of Freezing Moist Materials inside the Freeze Drying Chamber to Preserve Valuable Products
Số 70B - 2022
Freeze drying is one of the most advanced drying technologies for food processing and preserving using temperature under 0oC or under the freezing point, and pressure of drying chamber environment under 4.58mmHg to process foods. This method helps to maintain the initial quality of proteins, lipids, carbohydrates, vitamins, bioactive substances and sensory activities… In this study, the calculatio...... hiện toàn bộ

Review on polychlorinated naphthalenes (pcns): properties, sources, characteristics of emission and atmospheric level
Số 59 - 2020
Polychlorinated Naphthalenes (PCNs) have been included as new persistent organic pollutants (POPs) under Stockholm Convention in May, 2015. Thereafter, various studies working on the occurrence, toxicity and characteristics of PCNs in all environmental matrices and emission sources were conducted worldwide. However, these kinds of study have never been done in Vietnam, where has a high potential o...... hiện toàn bộ

Critical success factors for e-learning at university level: A case study from Da Nang University of Technology and Education (UTE-DN)
Số 62 - 2021
E-learning has become a trend in university education around the world. Also, the EMVITET Erasmus+ project in developing Education 4.0 has focused on developing e-learning. This study investigates the effect of critical success factors (CSFs) on e-learning at Da Nang University of Technology and Education (UTE-DN), a member of The University of Danang. Five categories were firstly identified via t...... hiện toàn bộ

Structure and Procedure for Developing an Online Course
Số 62 - 2021
Online teaching or e-learning allows learners to participate in a virtual classroom environment based on web and based on digital applications or digital tools, to interact with learning content and (possibly) with teacher and other peers from a long distance to achieve learning goals defined by their learning needs. The article provides some theoretical backgrounds of online teaching related to t...... hiện toàn bộ

Modeling and Simulation of PID Controller-Based Active Suspension System for A Quarter Car Model
Số 68 - 2022
The most common automotive suspension systems have been used passive components with fixed damping coefficient and spring constant. They are two separate functions to reach a compromise between drive quality and handling performance. Because of the limit of structures, the passive suspension system could hardly enhance the two features at the same time. In recent years, the active suspension syste...... hiện toàn bộ
