There exist errors between the manufactured workpieces and the CAD models due to the springback of sheet-metal incremental air-bending forming.
Because there exist errors in the initial value at the starting time, and the random periodic solutions are sensitive to the initial value, we can only deal with SDEs whose random periodic solutions are mean-square uniformly asymptotically stable.
For the pollutant source identification of multiple point sources in a water pollution incident, there exists certain error even mistake, because this kind of "inverse problem" is a so called "ill-posed problem" mathematically, which does not have a unique solution.
Note that there always exists errors in channel estimation by using outdated CSI due to the channel variant characteristics of R→D links, and those errors will consequently deteriorate the relay selection if full CSI is employed.
If non-Gaussian interference is assumed in the radar, probably there exists some other error functions which give rise to better results, motivating the study to know if they fulfil the sufficient condition established in[1, 33].
Case 2. One error: when there exists one error in the column, only if the single error happens to be located at the erasure, the erasure can be recovered.
There exists an error floor for the minimum square error of channel estimation and the bit error rate (BER) even if the signal-to-noise ratio (SNR) is very high [27].
However, it is not easy because of the influence of setup error of measurement instrument, and there exists angular errors and displacement errors need to be identified simultaneously.
Since label proportions estimated by human in grid labeling may differ from the true label proportions, there possibly exist errors in label proportion p k.
The quality of the clinical chart is notoriously variable, so there may exist errors and distortions from missing symptoms and falsely rating symptoms as absent when reviewing a chart, because of the failure of the clinician to mention them in the chart, which would have been detected in a structured, face-to-face interview.
