Sentence examples for uncertain frequency from inspiring English sources

A control algorithm emulating a dynamic vibration absorber (DVA) is developed for a flexible structure subject to harmonic disturbances of uncertain frequency.

The resulting solution sets have been studied through various post-processing methods, including visualization of Pareto fronts, uncertain frequency response plots, time-domain simulations, and random vibration analysis.

Aiming at the complex frequency transformation, the low measurement resolution and the uncertain frequency linking precision in the traditional frequency linking method, a new frequency linking method is proposed based on phase group synchronization.

Because of the uncertain frequency of fireplace use, we have not included homes with fireplaces in our estimate, although they likely are important sources of indoor PM.

Frequency was measured using 8 categories: never, one off, less than once a month, once a month, once or twice a week, 3-6 times a week, daily use and uncertain frequency.

Furthermore, numerical results reveal the influences of various uncertainty resources on the upper and lower bounds of uncertain frequencies and uncertainty propagation percent.

The design of an adaptive learning regulator is addressed for uncertain minimum phase linear systems (with known bounds, known upper bound on system order, known relative degree, known high frequency gain sign) and for unknown exosystems (with unknown order, uncertain frequencies).

This paper presents the quantification of uncertain natural frequency for laminated composite plates by using a novel surrogate model.

If the panel study only relies on email or mobile phones, the tracking outcomes may be undermined due to uncertain use frequency (email) and possible disruption (mobile phones).

We were uncertain which frequency bands might exhibit changes in long-range synchronization because theta (here 4 8 Hz), alpha (here 9 14 Hz), and gamma (30 50 Hz) bands all have been implicated in various ways in such phase locking [2], [46] [49].

Although SNP arrays suffer notably from ascertainment bias and low marker resolution, pooled sequencing guarantees a high resolution, but produces uncertain allelic frequency profiles and remains blind to the individual genotypes and local haplotype structures.
