DOI: 10.1109/jsen.2024.3378916
Abstract: When the vibratory gyroscope works in rate integrating mode, the gain unbalance between driving circuits will lead to standing wave drift on the resonator, and the gain unbalance between detection circuits will also lead to… read more here.

DOI: 10.1177/0954406220913584
Abstract: With the rapid development of petroleum exploitation industry, vibrating screen actuated with a single frequency is unsuitable to separate cuttings from drilling fluid, since it usually results in screen blocking. Hence, for solving the above-mentioned… read more here.
