Systematic error control for deflectometry with iterative reconstruction

, 2021
The slope calculation of phase measuring deflectometry is essentially a problem finding correspondence between camera, screen and reflecting point, while the reflecting point suffers from an ambiguity problem.

Investigation of the effect of temperature and other significant factors on systematic error and measurement uncertainty in CMM measurements by applying design of experiments

Measurement, 2020
The design of experiments was used in this paper in order to determine the significance of particular factors for the parameters that indicate the quality of measurement results obtained by means of a coordinate measuring machine (CMM).

A cylindricity evaluation approach with multi-systematic error for large rotating components

Metrologia, 2020
For reduction of the cylindricity evaluation uncertainty for large rotating components with large radius and height, the cylindrical profile measurement model is designed with multi-systematic error considering eccentricity, probe offset, probe radius ...

Improved Smoothing Frequency Shifting and Filtering Algorithm for Harmonic Analysis With Systematic Error Compensation

IEEE transactions on industrial electronics (1982. Print), 2019
Different from the fast Fourier transform-based method, the frequency shifting and filtering (FSF) algorithm employs only a few simple operations in the time domain for harmonic analysis.

Elimination of systematic error in digital image correlation caused by intensity interpolation by introducing position randomness to subset points

Optics and lasers in engineering, 2019
A strategy called random subset is presented to reduce systematic error in digital image correlation caused by intensity interpolation. In classical digital image correlation techniques, the subset points fall at integer locations; by contrast, the ...

A Systematic Model of Machining Error Reduction in Robotic Grinding

IEEE/ASME transactions on mechatronics, 2020
Robotic grinding is a promising automatic technique for free-form surface manufacturing. One important problem that restrains the application of robotic grinding is the machining quality.

Systematic Unidirectional Error-Detecting Codes

IEEE Transactions on Computers, 1985
The theory and design of systematic \(t\)-unidirectional error-detecting codes are developed. Optimal systematic codes capable of detecting \(2, 3\), and \(6\) unidirectional errors using \(2, 3\), and \(4\) check bits, respectively, are given. For \(r\geq 5\) where \(r\) is the number of check bits, the systematic codes described here can detect up to
