Dilation and Erosion on the Triangular Tessellation: An Independent Approach
IEEE Access, 2018 In this paper, a new idea for morphological operations, i.e., dilation and erosion on the regular triangular tessellation is presented. The triangles have two orientations; they are addressed by zero-sum and one-sum triplets and called even and odd ...

A family of H-div-div mixed triangular finite elements for the biharmonic equation
Results in Applied Mathematics, 2022 A family of Pk+22×2-PkH(divdiv)mixed finite elements on triangular grids is constructed for the biharmonic equation. For the H(divdiv)mixed finite element functions, both the stress tensor and its divergence have continuous normal components, σh⋅nand ...

Two-Step Colouring of Grid Graphs of Different Types
Моделирование и анализ информационных систем, 2022 In this article, we consider the NP-hard problem of the two-step colouring of a graph. It is required to colour the graph in a given number of colours in a way, when no pair of vertices has the same colour, if these vertices are at a distance of 1 or 2 ...

Bijective, Non-Bijective and Semi-Bijective Translations on the Triangular Plane
Mathematics, 2019 The triangular plane is the plane which is tiled by the regular triangular tessellation. The underlying discrete structure, the triangular grid, is not a point lattice. There are two types of triangle pixels. Their midpoints are assigned to them.

Effect of boundaries on grid cell patterns
Physical Review Research, 2020 Mammalian grid cells represent spatial locations in the brain via triangular firing patterns that tessellate the environment. They are regarded as the biological substrate for path integration and to provide an efficient code for space.

Stress Distribution on Sandwich Structure with Triangular Grid Cores Suffered from Bending Load
International Journal of Aerospace Engineering, 2015 Triangular grid reinforced by carbon fiber/epoxy (CF/EP) was designed and manufactured. The sandwich structure was prepared by gluing the core and composite skins.

CYCLIC PROPERTIES OF TRIANGULAR GRID GRAPHS [PDF]
IFAC Proceedings Volumes, 2006 Abstract It is known that all 2-connected, linearly convex triangular grid graphs, with only one exception, are hamiltonian (Reay and Zamfirescu, 2000). In the paper, it is shown that this result holds for a wider class of connected, locally connected triangular grid graphs and, with more exceptions, even for some general class of graphs.
