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 ...
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, ...
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 ...

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 ...
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 ...
