Planar and Quasi-Planar Simultaneous Geometric Embedding [PDF]

open access: yesThe Computer Journal, 2014
A simultaneous geometric embedding SGE of two planar graphs G 1 and G 2 with the same vertex set is a pair of straight-line planar drawings Γ1 of G 1 and Γ2 of G 2 such that each vertex is drawn at the same point in Γ1 and Γ2. Many papers have been devoted to the study of which pairs of graphs admit a SGE, and both positive and negative results have ...

Hydrodynamic simulation of hypervelocity generation by multidimensional graded impactors: Planarity enhancement study

open access: yesHeliyon, 2023
Hypervelocity impact in the universe can be generated by a three-stage gas gun. Achieving the desirable planarity of the flyer enlarges the experimentally effective area of the flyer under the hypervelocity condition.

Planar Depth and Planar Subalgebras

open access: yesJournal of Functional Analysis, 2002
In [Planar algebras. I (preprint math.QA/9909027)] planar algebras were introduced by \textit{V. F. R. Jones} to get insight in the study of subfactors, especially in the algebraic-combinatorial aspects of the lattice of higher relative commutants. To each extremal type \(II_1\) finite index subfactor inclusion, Jones has associated a spherical \(C^*\)-

Recognizing IC-Planar and NIC-Planar Graphs

open access: yesJournal of Graph Algorithms and Applications, 2018
We prove that triangulated IC-planar graphs and triangulated $K_5$-free or $X4W$-free NIC-planar graphs can be recognized in cubic time. A graph is 1-planar if it can be drawn in the plane with at most one crossing per edge. A drawing is IC-planar if, in addition, each vertex is incident to at most one crossing edge and NIC-planar if two pairs of ...

Inverse Neutrosophic Planar Graphs and its application in optimizing the expenditure in inter-cropping [PDF]

open access: yesNeutrosophic Sets and Systems
Though Neutrosophic graphs have high impact on dealing with problems of indeterminacy, it may not directly address all aspects of edge membership degree constraints such as the truth membership degree of all edge is greater than or equal to the minimum ...

A Multiview Stereo Algorithm Based on Image Segmentation Guided Generation of Planar Prior for Textureless Regions of Artificial Scenes

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Textureless building surfaces composed of homogenized pixels could lead to failure of photometric consistency. However, textureless regions widely present in artificial scenes usually exhibit strong planarity enabling depth estimation of textureless ...

Clustered Planarity = Flat Clustered Planarity [PDF]

open access: yes, 2018
The complexity of deciding whether a clustered graph admits a clustered planar drawing is a long-standing open problem in the graph drawing research area. Several research efforts focus on a restricted version of this problem where the hierarchy of the clusters is "flat", i.e., no cluster different from the root contains other clusters.
