PDE-based multi-agent formation control using flatness and backstepping: analysis, design and robot experiments [PDF]
at - Automatisierungstechnik, 2019 A PDE-based control concept is developed to deploy a multi-agent system into desired formation profiles. The dynamic model is based on a coupled linear, time-variant parabolic distributed parameter system.

Flatness of the Meckel cave may cause primary trigeminal neuralgia: a radiomics-based study
The Journal of Headache and Pain, 2021 Background Neurovascular contact (NVC) is the main cause of primary trigeminal neuralgia (PTN); however, cases of PTN without NVC are still observed. In this study, the Meckel cave (MC) morphology in PTN were analyzed by radiomics and compared to healthy

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

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

Flatness pattern recognition of ultra-wide tandem cold rolling mill
工程科学学报, 2021 A cubic flatness pattern expressed by Legendre orthogonal polynomial was introduced to build a new flatness pattern recognition model,in which least squares regression was used.

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

Journal of Intelligent Manufacturing, 2020 The acceptance of the machined surfaces not only depends on roughness parameters but also in the flatness deviation (Δfl). Hence, before reaching the threshold of flatness deviation caused by the wear of the face mill, the tool inserts need to be changed

Assessment of flatness error by regression analysis
, 2021 The geometric tolerancing (GPS or GD&T) has increasing importance in machine design, manufacturing and measuring. The geometric tolerances define the deviation of the different kinds of geometric elements in more sophisticated way, than dimensional ...

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

Journal für die reine und angewandte Mathematik (Crelles Journal), 1993 Let \(Y\subset\mathbb{R}^ n\) be a codimension one analytic set, and fix a signature \(\sigma\) on \(\mathbb{R}^ n\backslash Y\) \((\sigma\) associates a \(\text{sign}+1\) or \(-1\) to each connected component of \(\mathbb{R}^ n\backslash Y)\). The signature \(\sigma\) is admissible at \(x\in Y\) when the germ \(\sigma_ x\) is induced by a germ of ...
