The controllers regulate the vibration response measured by sensors, and the output control signal is the feedback to the actuators after power amplifying. The active method can be adapted online, and the control efficiency and accuracy are higher than the passive one. The key work of the ...
Abstract: The STEM approach is a student-centred teaching and learning process that involves an inquiry process in problem-solving questions. This study was conducted to examine the effectiveness of the STEM approach in enhancing students' mathematics performance. The study used a quasi- experimental ...

That is, at first, the speed of generation is slow and user awareness is low. However, the speed of development becomes faster and more recognizable to users as time passes. Ultimately, it reaches a certain limit and a new life cycle begins. In a capitalist society, the value of an ...
Introduction The air we breathe is composed of roughly 78% nitrogen (N2), 21% oxygen (O2), 0.9% argon (Ar), 0.03% carbon dioxide (CO2), and 0.07% other gases. Six pollutants have been identified as the main sources of air pollution [1]. In addition to lead and particulate matter, ...
The sequence investment program is to complete the investment in the first stage of the introduction period (product innovation), and then have the opportunity to invest in the next stage. After completing the second stage of growth (manufacturing innovation) innovation investment, the program has ...
Knowledge management can contribute to understanding the situation and gaps of different researchers/research institutions, and define agendas for future research [12]. However, there is usually a knowledge gap between the knowledge what has been already known and the knowledge in practical application,...
As part of the vast field of microfluidic application, the role of the microfluidic chip in synthetic chemistry and biology creates a new instrumental platform that is the microfluidic reaction system. It deals with the material synthesis by the flow of a minute amount of liquid (which can be ...
Even in Middle Eastern countries where energy costs are lower such as Saudi Arabia, UAE, Qatar, and Kuwait, almost all desalination plants where only water production is required have adopted the RO method. However, large plants in excess of half mega-ton size are required, and Seawater ...
