Journal ArticleDOI
Data-Driven Modeling of the Modal Properties of a Six-Degrees-of-Freedom Industrial Robot and Its Application to Robotic Milling
TL;DR: The results show that the GPR model presented in this paper can serve as a useful tool for understanding and optimizing the tool tip vibrations produced in robotic milling.
Journal ArticleDOI
Quantization noise, fixed-point multiplicative roundoff noise, and dithering
TL;DR: It is shown that regardless of the probability distribution of the input signal x/sub n/, it is always possible to add a suitable dither signal to the input of the system so that both the quantization error and the roundoff error are uniformly distributed, white, and mutually uncorrelated.

Cascaded models and the DQE of flat-panel imagers: noise aliasing, secondary quantum noise, and reabsorption
TL;DR: In this paper, the authors present the governing principles of cascaded models and conditions that must be satisfied to prevent misuse of such models, including the Lubberts effect, secondary quantum noise, reabsorption of K x rays from photo-electric interactions, and noise aliasing.

Band moiré images
Roger D. Hersch,Sylvain Chosson +1 more
TL;DR: A mathematical model describing the geometric transformation that a moire image undergoes, when its base layer and its revealing layer are subject to different freely chosen non-linear geometric transformations is proposed.

La spectroscopie de photoélectrons induits par rayons X et la répartition des ions cuivre Cu+ et Cu2+ dans les ferrites de cuivre
TL;DR: In this paper, it was shown that copper is monovalent and divalent and that Cu 2+ and Cu + cations are found in the tetrahedral and octahedral O 2− anion environments.
