Elastic Analysis of Irregularly or Sparsely Sampled Curves [PDF]

Biometrics, 2022
Abstract We provide statistical analysis methods for samples of curves in two or more dimensions, where the image, but not the parameterization of the curves, is of interest and suitable alignment/registration is thus necessary. Examples are handwritten letters, movement paths, or object outlines.

Integrable quadratic Hamiltonians on the Euclidean group of motions [PDF]

, 2010
This paper tackles the problem of globally computing sub-Riemannian curves on the Euclidean group of motions SE(3). In particular we derive a global result for special sub-Riemannian curves for which their Hamiltonian satisfies a particular condition ...

Uniform fatigue damage tolerance assessment for additively manufactured and cast Al-Si alloys: size and mean stress effects

Additive Manufacturing Letters, 2022
The near-net-shape manufacturing in additive manufactured and cast of Al-Si alloys results in a heterogeneous solidification and cooling of the parts, leading to significant gradients in microstructural and defect features as well as deformation behavior.

Evolution characteristics of elastic energy storage of marble under creep loading

矿业科学学报, 2022
In order to study the energy absorption and transformation characteristics of marble, the release of strain energy and dissipation mechanism during creep process, this paper tested the stress-strain relationship of marble under uniaxial cyclic loading ...

The curvature of plane elastic curves [PDF]

, 1993
In this paper plane elastic curves are revisited from a viewpoint that emphasizes curvature properties of these curves. The family of elastic curves is considered in dependence of a tension parameter Sigma and the squared global curvature maximum K2/m ...

Curves in the Lorentz-Minkowski plane with curvature depending on their position

Open Mathematics, 2020
Motivated by the classical Euler elastic curves, David A. Singer posed in 1999 the problem of determining a plane curve whose curvature is given in terms of its position. We propound the same question in the Lorentz-Minkowski plane, focusing on spacelike

Black rubber and the non-linear elastic response of scale invariant solids

Journal of High Energy Physics, 2020
We discuss the nonlinear elastic response in scale invariant solids. Following previous work, we split the analysis into two basic options: according to whether scale invariance (SI) is a manifest or a spontaneously broken symmetry.

Elastic Sturmian spirals in the Lorentz-Minkowski plane

Open Mathematics, 2016
In this paper we consider some elastic spacelike and timelike curves in the Lorentz-Minkowski plane and obtain the respective vectorial equations of their position vectors in explicit analytical form.
