Composite error prediction of multistage machining processes based on error transfer mechanism

The International Journal of Advanced Manufacturing Technology, 2014
Nowadays, modern manufacturing enterprises are paying more and more attention to machining process quality control in order to ensure the product quality. Since machining quality fluctuation is performed as composite error, then error control is becoming the key point in product quality assurance.

Global Composite Learning Fixed-Time Control of Robotic Systems With Asymmetric Tracking Error Constraints

IEEE transactions on industrial electronics (1982. Print), 2023
Superior parameter convergence is desirable in adaptive robot control as it can enhance the overall stability of the closed-loop system. However, most current studies of adaptive robot control concentrate on parameter convergence in the steady state ...

Measurement error in compositional data

Journal of the International Association for Mathematical Geology, 1984
Compositional data, consisting of vectors of proportions summing to unity such as the geochemical compositions of rocks, have proved difficult to analyze. Recently, the introduction of logistic and logratio transformations between the d-dimensional simplex and Euclidean space has allowed the use of familiar multivariate methods.
