Investigation of Functional Dependency between the Characteristics of the Machining Process and Flatness Error Measured on a CMM

open access: yesMeasurement Science Review, 2021
Numerous studies have shown that the choice of measurement strategy (number and position of measurement points) when measuring form error on a coordinate-measuring machine (CMM) depends on the characteristics of the machining process which was used to ...

Flatness of the setting Sun [PDF]

open access: yes, 2002
Atmospheric refraction is responsible for the bending of light-rays in the atmosphere. It is a result of the continuous decrease in the refractive index of the air as a function of altitude.

Flat semimodules [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We introduce and investigate flat semimodules and k‐flat semimodules .We hope these concepts will have the same importance in semimodule theory as in the theory of rings and modules.

Stabilize and Flatten Multi-Wavelength Erbium-Doped Fiber Laser through Accurate Hybrid Dual-Ring-Configuration Control

open access: yesApplied Sciences, 2017
In order to enhance the practicality of multi-wavelength erbium-doped fiber lasers (MWEDFLs), a novel hybrid dual-ring configuration is proposed in this article, which can flatten the outputs through an optical nonlinear-polarization-rotation-based ring ...

Wake Width: Discussion of Several Methods How to Estimate It by Using Measured Experimental Data

open access: yesEnergies, 2021
Several methods of defining and estimating the width of a turbulent wake are presented and tested on the experimental data obtained in the wake past an asymmetric prismatic airfoil NACA 64(3)-618, which is often used as tip profile of the wind turbines ...

Flatness properties of acts over semigroups [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2021
In this paper we study flatness properties (pullback flatness, limit flatness, finite limit flatness) of acts over semigroups. These are defined by requiring preservation of certain limits from the functor of tensor multiplication by a given act. We give

Digital modeling geometrical and macrorough parameters of a highway [PDF]

open access: yesКомпьютерные исследования и моделирование, 2012
Original representation of statistical digital model of measurement of a macroroughness on a local site (to 15) consisting of determined (bias), correlated (standard periodic making and periodic deviations from flatness) and actually casual making ...

Generation of Flat Terahertz Noise by Mixing Incoherent Light Fields

open access: yesPhotonics, 2023
Terahertz (THz) noise sources play an irreplaceable role in testing THz devices and evaluating THz application systems, and the flatness of their radio frequency (RF) spectra is an important technical parameter.
