Laser Scanning and the Continuous Wavelet Transform for Flatness Control [PDF]
, 2015 Current methods for surface flatness control in construction are based on sparse measurements and therefore may lead to inaccurate and imprecise results.

Safe certificate-based maneuvers for teams of quadrotors using differential flatness [PDF]
IEEE International Conference on Robotics and Automation, 2017 Safety Barrier Certificates that ensure collision-free maneuvers for teams of differential flatness-based quadrotors are presented in this paper. Synthesized with control barrier functions, the certificates are used to modify the nominal trajectory in a ...

Flatness and Monge parameterization of two-input systems, control-affine with 4 states or general with 3 states [PDF]
, 2005 This paper studies Monge parameterization, or differential flatness, of control-affine systems with four states and twocontrols. Some of them are known to be flat, and this implies admitting a Monge parameterization.

Heredity and evolution laws of flatness defects in steel strip temper rolling processes
工程科学学报, 2015 Three-dimensional temper rolling processes are simulated by nonlinear elastoplastic finite element software called ABAQUS. In this simulation, the initial flatness defects of steel strips are modeled by the temperature field, and the adjustment effect of

Measurement 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 ...

Representability of Hom implies flatness [PDF]
, 2003 Let $X$ be a projective scheme over a noetherian base scheme $S$, and let $F$ be a coherent sheaf on $X$. For any coherent sheaf $E$ on $X$, consider the set-valued contravariant functor $Hom_{E,F}$ on $S$-schemes, defined by $Hom_{E,F}(T) = Hom(E_T,F_T)$

Flatness and Submersivity of Discrete-Time Dynamical Systems
IEEE Control Systems Letters, 2020 This letter addresses flatness of discrete-time systems called difference flatness. A definition of flatness, that encompasses the standard ones, in particular backward and forward difference flatness, is introduced.

Curvatures, graph products and Ricci flatness [PDF]
Journal of Graph Theory, 2019 In this paper, we compare Ollivier–Ricci curvature and Bakry–Émery curvature notions on combinatorial graphs and discuss connections to various types of Ricci flatness.
