Covering the Plane with Translates of a Triangle [PDF]

Discrete & Computational Geometry, 2009
The author proves that the minimum density of a covering of the plane by translates of a triangle is 3/2. This establishes that triangles are the least economical sets for translative plane covering.

THE FULFILLED EUCLIDEAN PLANE [PDF]

, 2002
The fulfilled euclidean plane is the real projective plane completed with the infinite point of its infinite line. This new incidence structure is a structure with neighbouring elements, in which the unicity of the line through two distinct points is not

Collineation groups of translation planes of small dimension

International Journal of Mathematics and Mathematical Sciences, 1981
A subgroup of the linear translation complement of a translation plane is geometrically irreducible if it has no invariant lines or subplanes. A similar definition can be given for “geometrically primitive”.

Full-Field Vibration Measurements by Using High-Speed Two-Dimensional Digital Image Correlation

Applied Sciences, 2023
This work developed a method that uses a single monochrome high-speed camera without sacrificing the spatial resolution to measure both in-plane and out-of-plane full-field vibrations.

Cranio-caudal and medio-lateral navicular translation are representative surrogate measures of foot function in asymptomatic adults during walking.

PLoS ONE, 2018
IntroductionThe translation of the navicular bone is thought to be a representative surrogate measure to assess foot pronation and hence foot function; however, it is not known how it is related to multi-segment foot kinematics.MethodsCranio-caudal (NCC)

Two infinite families of polyominoes that tile the plane by translation in two distinct ways [PDF]

, 2011
It has been proved that, among the polyominoes that tile the plane by translation, the so-called squares tile the plane in at most two distinct ways. In this paper, we focus on double squares, that is, the polyominoes that tile the plane in exactly two ...

Weighted minimal translation surfaces in the Galilean space with density

Open Mathematics, 2017
Translation surfaces in the Galilean 3-space G3 have two types according to the isotropic and non-isotropic plane curves. In this paper, we study a translation surface in G3 with a log-linear density and classify such a surface with vanishing weighted ...
