(k, p)-Planarity: A Relaxation of Hybrid Planarity [PDF]
Theoretical Computer Science, 2018 We present a new model for hybrid planarity that relaxes existing hybrid representations. A graph $G = (V,E)$ is $(k,p)$-planar if $V$ can be partitioned into clusters of size at most $k$ such that $G$ admits a drawing where: (i) each cluster is associated with a closed, bounded planar region, called a cluster region; (ii) cluster regions are pairwise ...

Broadband Compact Quasi Yagi Antenna for UHF Wireless Communication Systems with Enhanced Performance at UHF ISM Bands [PDF]
Radioengineering, 2020 In this study, a broadband planar quasi Yagi antenna operated at ultra-high frequency (UHF) band is presented. The performance of the antenna is particularly improved for two popular UHF frequencies of 433 and 868 MHz used in several wireless ...

Planar and Quasi-Planar Simultaneous Geometric Embedding [PDF]
The 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 ...

Porous Polypropylene Membrane Based pH Sensing for Skin Monitoring
IEEE Access, 2022 An iridium oxide-based electrical pH sensor that is suitable to be embedded in an electronic bandage for skin monitoring has been developed. The electrical pH sensor does not entail high-temperature fabrication processes thus is suitable to be built on ...

Theoretical Computer Science, 2018 We introduce the family of $k$-gap-planar graphs for $k \geq 0$, i.e., graphs that have a drawing in which each crossing is assigned to one of the two involved edges and each edge is assigned at most $k$ of its crossings. This definition is motivated by applications in edge casing, as a $k$-gap-planar graph can be drawn crossing-free after introducing ...

Clustered Planarity = Flat Clustered Planarity [PDF]
, 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.
