Some Star Related Vertex Odd Divisor Cordial Labeling of Graphs

Abstract

are vertex odd divisor cordial graphs. Also, investigated lots of properties.

Reactive Power Injection to Grid Using Transformer-Less MOSFET Based Single Phase Inverter Using PV to Achieve High Efficiency

“…Energy is said to be stored in this stage and hence is called energy storage mode. 𝑉 = 0 [11] Figure 3. Switching pulses for six switches…”

“…This fluctuation causes common mode leakage current to flow which causes electromagnetic distortion, harmonics, interferences and other power quality issues. The efficiency of the system is reduced by these power quality issues.To avoid the issue of leakage current generation due to absence of galvanic isolation, the transformer is removed which leads to new topology that is HERIC where two IGBTs are used instead of two IGBTs and two diodes (11). But, IGBTs have high switching losses and are not very suitable for high frequency and fast switching operation.…”

Algorithm for Finding Roman Dominating Number of Extended Duplicate Graph of Star Families

“…K.Thirusangu and M.Madhu[4] introduced extended duplicate graph of star and bistar graphs. S K Vaidya and N H Shah[5] studied some Star and Bistar Related Divisor Cordial graphs. This paper determines the roman dominating number for extended duplicate graph of star, doublestar and bistar and gives an algorithm to find the roman dominating number.…”
