thin-film pressure sensors are based on the strain effect of metals and are widely used in the automotive electronics and aerospace fields, especially as ultralow-temperature pressure sensors. However, the fabrication cost is excessively high for batch consumer electronic applications. The sensing mater...
When choosing drip tape, it is important to watch the quality of its filtration area where the water is released. Large, seamlessly integrated filtration areas and a low emitter profile are essential quality criteria to ensure uniform water flow. ...
There is an urgent need for scientific management of urban air systems. Mathematical modeling of air quality helps the researchers and urban authorities in devising scientific management plans for mitigation of the associated impacts. We present an organized review of the broad aspects related to ...
