The formation index is a measure used in paper manufacturing to assess the uniformity and distribution of fibers within a sheet of paper, impacting its strength, printability, and overall quality. A higher formation index indicates a more evenly distributed fiber network, leading to better performance and appearance of the final paper product.
Seismic sensors are devices used to detect and measure ground motion, typically for monitoring earthquakes and other seismic events. They play a crucial role in geophysical research, infrastructure safety, and early warning systems by providing data on the intensity and location of seismic activities.
