Laser distance meters are easy to use, accurate, and accessible hand-held devices that can measure up to 150-250 metres, making them versatile in everyday use. They are the ideal option for projects ...

Abstract: With the rapid development of high-voltage direct current (HVdc) transmission technology, the demand for monitoring the DC total electric field at ground level has increased significantly.

Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

While liver stiffness measurement by vibration-controlled transient elastography with a 25 kPa threshold might detect CSPH, the overall low quality of the studies means that these results are not very ...

Abstract: Precise wideband impedance measurement for a power grid is crucial for small-signal stability analysis of the grid-connected converter system. Various techniques have been investigated for ...
