Tangent Lines and Lipschitz Differentiability Spaces [PDF]
Analysis and Geometry in Metric Spaces, 2016 We study the existence of tangent lines, i.e. subsets of the tangent space isometric to the real line, in tangent spaces of metric spaces.We first revisit the almost everywhere metric differentiability of Lipschitz continuous curves.

The Kabod: The Journal of the Liberty University Honors College, 2018 In [1] Leibniz published the first treatment of the subject of calculus. An English translation can be found in [2]; he says that to find a tangent is to draw a right line, which joins two points of the curve having an infinitely small difference, or the

Ferenczi’s times: the tangent-out, the segments, the meandering line [PDF]
American Imago, 2015 The article examines Sándor Ferenczi’s ideas about time and psychoanalytic technique. It proposes three metaphors for making sense of Ferenczi’s times: originary time (the tangent-out), organic time (segments), and pulsating time (the meandering line ...

A Geometrically Exact Curved Beam Element Based on Cubic Spline Interpolation [PDF]
Zhengzhou Daxue xuebao. Gongxue ban, 2023 To accurately model and simulate the multibody system including large deformation beams, a 2D large deformation curved beam element, which had few element parameters and can be integrated with the CAD geometric model, was proposed based on cubic spline

Affine Subspace Concentration Conditions [PDF]
Épijournal de Géométrie Algébrique, 2023 We define a new notion of affine subspace concentration conditions for lattice polytopes, and prove that they hold for smooth and reflexive polytopes with barycenter at the origin.

Existence of tangent lines to Carnot–Carathéodory geodesics [PDF]
Calculus of Variations and Partial Differential Equations, 2018 We show that length minimizing curves in Carnot-Carathéodory spaces possess at any point at least one tangent curve (i.e., a blow-up in the nilpotent approximation) equal to a straight horizontal line. This is the first regularity result for length minimizers that holds with no assumption on either the space (e.g., its rank, step, or analyticity) or ...

Maxillofacial Plastic and Reconstructive Surgery, 2019 Background To test the hypothesis that in profile smiling view, for ideal aesthetics, a tangent to the labial face of the maxillary central incisor crowns should be approximately parallel to the true vertical line and thereby perpendicular to the true ...

THE STUDY OF TANGENCY TO CONICAL SURFACES
Journal of Industrial Design and Engineering Graphics, 2019 This paper aims to study the problem of tangency of straight lines and planes, with application at conical surfaces. With the help of descriptive geometry knowledge, the plane and straight lines tangent to the conical surfaces are being determined ...

Rigidity properties of holomorphic Legendrian singularities [PDF]
Épijournal de Géométrie Algébrique, 2019 We study the singularities of Legendrian subvarieties of contact manifolds in the complex-analytic category and prove two rigidity results. The first one is that Legendrian singularities with reduced tangent cones are contactomorphically biholomorphic to
