Development of an On-Board Measurement System for Railway Vehicle Wheel Flange Wear
Sensors, 2020 The maintenance of railway systems is critical for their safe operation. However some landscape geographical features force the track line to have sharp curves with small radii. Sharp curves are known to be the main source of wheel flange wear.

Mathematische Annalen, 2015 The purpose of this paper is to interpret the phase transition in the Loewner theory as an analog of the hyperbolic variant of the Schur theorem about curves of bounded curvature. We define a family of curves that have a certain conformal self-similarity property. They are characterized by a deterministic version of the domain Markov property, and have

High curvatures drive river meandering
Geology, 2019 We thank Finotello et al. (2019) for their Comment on our analysis of the link between migration rate (M) and curvature (C). While their analysis calls attention to an interesting flattening of the migration rate curve at the highest curvatures, we ...

Conformal metrics with prescribed gaussian and geodesic curvatures [PDF]
Annales Scientifiques de l'Ecole Normale Supérieure, 2018 We consider the problem of prescribing the Gaussian and the geodesic curvatures of a compact surface with boundary by a conformal deformation of the metric.

Journal of the Mechanical Behavior of Materials, 2014 This paper elaborates that at micro/nanoscales, highly curved matter spaces may induce abnormal driving forces. Such abnormal driving forces are controlled by two fundamental factors: one is the bending extent of surfaces (curvature) and another is the ...

Special helices on equiform differential geometry of timelike curves in E_1^4
Cumhuriyet Science Journal, 2021 In this paper, we introduce the moving Frenet frame along the timelike curve in E_1^4 and then Frenet formulas with the equiform parameter in the equiform geometry of the Minkowski space-time.

Scalar Curvature and Q-Curvature of Random Metrics [PDF]
The Journal of Geometric Analysis, 2010 We study Gauss curvature for random Riemannian metrics on a compact surface, lying in a fixed conformal class; our questions are motivated by comparison geometry. Next, analogous questions are considered for the scalar curvature in dimension $n>2$, and for the $Q$-curvature of random Riemannian metrics.

Integral Formulas for a Class of Curvature PDE'S and Application to Isoperimetric Inequalities and to Symmetry Problems [PDF]
, 2007 We prove integral formulas for closed hypersurfaces in C^(n+1); which furnish a relation between elementary symmetric functions in the eigenvalues of the complex Hessian matrix of the defining function and the Levi curvatures of the hypersurface. Then

A Design Optimization Study for the Die Dimensioning Using the Locking Nut Folding Simulation
Journal of Mechanical Engineering, 2021 An inverse analysis based on optimization process is performed to determine die curvatures for a locking nut’s flange folding process which has highly nonlinear material behaviour. The nut material is AISI C1040 steel.

Extended curvatures and Lie pseudoalgebras [PDF]
ITM Web of Conferences, 2022 The aim of the paper is to prove that if some extended curvatures on a preinfinitesimal module L, considered in the paper, vanish, then the derived preinfinitesimal module L(1) is a Lie pseudoalgebra. Two non-trivial examples are given. The first example
