It had already trimmed the frequency of the service on the route.
In an atomic clock these quantum transitions are observed and maintained in a feedback loop that trims the frequency of the electromagnetic radiation; like the recurrent events in other types of clocks, these waves are then counted.
The presented frequency trimming technique is based on assessing the modes mismatch and cross-coupling between modes by means of fitting the experimental frequency response curves to the analytical solutions of the dual-mass system in presence of imperfections.
Additionally, the vibration mode shapes are presented, and the frequency trimming concept due to attached imperfections is investigated.
In order to make MEMS oscillators suitable for system applications, a review of two of the biggest technical challenges, frequency trimming and temperature compensation, is presented.
This paper proposes a method for trimming the natural frequencies of an imperfect ring to simultaneously eliminate certain of the frequency splits present.
This paper presents a practical method for trimming the natural frequencies of an initially imperfect ring to simultaneously eliminate certain of the frequency splits present.
A model cavity is designed to verify the frequency modulation trimming algorithm featuring a half-wave structure and eight sets of rotating blades for 1 kHz frequency modulation.
This work proposes a practical mass trimming approach for eliminating the frequency splits between these four natural frequencies for an initially imperfect ring.
Even after having trimmed down the frequency and switched to a smaller, Boeing 787 plane, BA has confirmed that the service will end this January.
