There are three noise generation mechanisms; (i) acceleration noise, (ii) ringing noise due to longitudinal waves (vibration), and (iii) ringing noise due to flexural (bending) waves. Acceleration noise is dominant for the two spheres. For the cylinders, flexural ringing noise radiation is ...

This chapter defines noise as undesirable signals that are present in a circuit. Too much noise is a typical problem confronting many circuit designers. Once one evaluates where the noise sources are, eliminating circuit noise may be quite simple. Tools such as filters or lower noise devices prov...
The experimental results on 34 simulated and two real-world data sets consistently show that TDNC significantly outperforms the existing state-of-the-art noise correction algorithms in terms of the noise ratio. 展开 关键词: Crowdsourcing learning Noise correction Three-way decision ...

We developed an efficient method to quickly explore contrast sensitivity as a function of nine spatial frequencies at three levels of external noise in both young and old subjects. Fifty-two young and twenty-six old subjects have been screened for ophthalmological and mental diseases and participated...
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self–sustaining force proportional to its own velocity. This system
In droplet-based single-cell and single-nucleus RNA-seq experiments, not all reads associated with one cell barcode originate from the encapsulated cell. Such background noise is attributed to spillage from cell-free ambient RNA or barcode swapping event
(two, three, or four nodal diameters) with nodal spacing greater than the pad length. Squeal noiseis particularly difficult to suppress because circumferential symmetry in a brake disc or drum allows vibrational energy to be continually transferred between two closely spaced modal frequencies (‘...
20 (Xinhua) -- China has released a three-year action plan for noise pollution prevention and control at civil airports, as part of its efforts to promote the green transformation of civil aviation. The plan was jointly issued by the Civil Aviation Administration of China, the Ministry of ...
