An equitable(O^(1)_(k),O^(2)_(k),...,O^(m)_(k))-partition of a graph G,which is also called a k cluster m-partition,is the partition of V(G)into m non-empty subsets V_(1),V_(2),...,Vm such that for every integer i in{...
This study is to utilize the heat-absorbing and releasing capabilities of phase change materials(PCM)to regulate the surface temperature fluctuations of batteries during charging and discharging.The goal is to keep th...
Electric vehicles(EVs)are going to overrule the transportation sector due to their pollution-free technology and low running costs.However,charging the EVs causes significant power demand and stress on the power deliv...
