Planar Graphs with the Distance of 6--Cycles at Least 2 from Each Other Are DP-3-Colorable
Mathematics, 2020 DP-coloring as a generalization of list coloring was introduced by Dvořák and Postle recently. In this paper, we prove that every planar graph in which the distance between 6−-cycles is at least 2 is DP-3-colorable, which extends the result of Yin and Yu

Additive List Coloring of Planar Graphs with Given Girth
Discussiones Mathematicae Graph Theory, 2020 An additive coloring of a graph G is a labeling of the vertices of G from {1, 2, . . . , k} such that two adjacent vertices have distinct sums of labels on their neighbors.

Alternating Battery Discharge Method Using Discharge Time Balancing
Journal of IKEEE, 2015 This paper proposes an alternating battery discharge method by balancing discharge time of battery cells, which significantly increases battery lifetime. In the conventional method, several battery cells are alternately discharged to make battery recovery effect, and this increases battery lifetime.

Partial discharges measurement by UHF method
Zbornik radova Elektrotehnicki institut Nikola Tesla, 2020 The unconventional UHF (Ultra High Frequency) method of measuring partial discharges (PD) is based on measuring electromagnetic waves (EM) in the UHF frequency band (300-3000) MHz, using appropriate antennas. This method is unconventional, but is widely accepted due to the possibility of application in plants in the online mode and quick review ...

On Edge Colorings of 1-Planar Graphs without 5-Cycles with Two Chords
Discussiones Mathematicae Graph Theory, 2019 A graph is 1-planar if it can be drawn on the plane so that each edge is crossed by at most one other edge. In this paper, it is proved that every 1-planar graph with maximum degree ∆ ≥ 8 is edge-colorable with ∆ colors if each of its 5-cycles contains ...
