Flatness optimization of micro-injection moulded parts: The case of a PMMA microfluidic component [PDF]

open access: yes, 2011
Micro-injection moulding (µ-IM) has attracted a lot of interest because of its potential for the production of low-cost, miniaturized parts in high-volume.

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 ...

FPGA Design for On‐Board Measurement of Intermittency From In‐Situ Satellite Data

open access: yesEarth and Space Science, 2021
Intermittency is a fundamental property of space plasma dynamics, characterizing turbulent dynamical variables as well as passive scalars. Its qualitative and quantitative description from in‐situ data requires an accurate estimation of the probability ...

Dynamical Solutions to the Horizon and Flatness Problems [PDF]

open access: yes, 1993
We discuss in some detail the requirements on an early-Universe model that solves the horizon and flatness problems during the epoch of classical cosmology ($t\ge t_i\gg 10^{-43}\sec$).

Flatness of tracer density profile produced by a point source in turbulence [PDF]

open access: yes, 2003
The average concentration of tracers advected from a point source by a multivariate normal velocity field is shown to deviate from a Gaussian profile. The flatness (kurtosis) is calculated using an asymptotic series expansion valid for velocity fields ...

A Test for Differential Flatness by Reduction to Single Input Systems [PDF]

open access: yes, 1995
For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.

Laser Scanning and the Continuous Wavelet Transform for Flatness Control [PDF]

open access: yes, 2015
Current methods for surface flatness control in construction are based on sparse measurements and therefore may lead to inaccurate and imprecise results.

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 ...

Flat semilattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
Let S (respectively S 0 {{\mathbf {S}}_0} ) denote the category of all join-semilattices (resp. join-semilattices with 0) with (0-preserving) semilattice homomorphisms. For A ∈ S A \in

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.
