Measurements of the air gap magnetic flux density, the air gap length, as well as the magnetization and size of the permanent magnets have been performed. Correlations are calculated and causalities ...

As a consequence, current trends in criteria air pollutants such as NO 2, SO 2, CO, Pb, PM 2.5 cannot be effectively evaluated with observational data in those locations. This represents a data gap ...

An ultrasonic air pump that uses a traveling wave along a small air gap between a bending vibrator and a reflector is discussed. The authors investigate ultrasonic air pumps that make use of bending ...
