On the semicontinuity of curvatures [PDF]

open access: yesCommentarii Mathematici Helvetici, 1992
For a convex body \(K\) in \(\mathbb{R}^ n\) with a boundary of class \(C^ 2\) and positive curvatures and for \(\alpha\in\mathbb{R}\backslash\{0\}\) and \(j=1,\ldots,n-1\), let \[ \psi^ \alpha_ j(K)=\left\{{1\over\omega_ n}\int_{S^{n-1}}s_ j(K,u)^ \alpha d\omega(u)\right\}^{1/\alpha}, \] where \(s_ j(K,u)\) is the normalized \(j\)-th elementary ...

Mean Curvature in the Light of Scalar Curvature [PDF]

open access: yesAnnales de l'Institut Fourier, 2020
We formulate several conjectures on mean convex domains in the Euclidean spaces, as well as in more general spaces with lower bonds on their scalar curvatures, and prove a few theorems motivating these conjectures.

A Novel Approach for Software Defect prediction Based on the Power Law Function

open access: yesApplied Sciences, 2020
Power law describes a common behavior in which a few factors play decisive roles in one thing. Most software defects occur in very few instances. In this study, we proposed a novel approach that adopts power law function characteristics for software ...

Low-resolution spherical harmonics models in application to quasi-quadric particle shapes

open access: yesEngineering Structures and Technologies, 2016
In this paper a numerical analysis was performed developing low-resolution spherical harmonics (LRSH) models in order to describe particle shapes. The potential of LRSH, limited by the expansion degree L ≤ 3, to describe quasi-regular particle shapes was

Failure of Elliptical Tubes with Different Long–Short Axis Ratios under Cyclic Bending in Different Directions

open access: yesMetals, 2023
Although elliptical tubes are stronger and more stable than circular tubes, few studies have fully considered the behavior of elliptical tubes under cyclic bending loads. This study experimentally investigated the response and failure of SUS304 stainless

Loewner curvature

open access: yesMathematische 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

Curvature-Adjustable Polymeric Nanolens Fabrication Using UV-Controlled Nanoimprint Lithography

open access: yesMicromachines, 2022
Nanolenses are gaining importance in nanotechnology, but their challenging fabrication is thwarting their wider adoption. Of particular challenge is facile control of the lens’ curvature.

Anterior diaphyseal curvature of the femur and tibia has biomechanical consequences during unloaded uphill locomotion

open access: yesFrontiers in Ecology and Evolution, 2023
The biomechanics of limb bone curvature are complex, and though anterior curvature clearly exhibits some relationship with behavior, the mechanisms shaping it and its biomechanical purpose remain unclear. Among both Neanderthals and humans, anterior limb
