In the future, voice communication is expected to migrate from the Public Switched Telephone Network (PSTN) to the Internet. Because of the particular characteristics (low volume and burstiness) and stringent delay and loss requirements of voice traffic, it is important to separate voice traffic from other traffic in the network by providing it with a separate queue. In this study, we conduct a...

The k-Leaf Root problem is a particular case of graph power problems. Here, we study “error correction” versions of k-Leaf Root—that is, for instance, adding or deleting at most l edges to generate a graph that has a k-leaf root. We provide several NP-completeness results in this context, and we show that the NP-complete Closest 3Leaf Root problem (the error correction version of 3-Leaf Root) i...

Topology for closed loop reactive power compensation suitable for dynamic loads using TCR is presented. Firing angle range of TCR is selected in such a way to keep the harmonic content at a minimum level. Simulation results show that the proposed scheme can achieve reactive power compensation in less than a half cycle and the harmonics contents of source are maintained at insignificant levels d...

elevated levels of C-reactive protein, and it persisted after the acute event. Moreover, TCR dim cells were also more represented within CD8 T cell, NK, and CD4 CD28 T cell subsets in ACS compared to CSA and controls. Finally, CD4 and CD8 TCR dim T cells isolated from ACS displayed an enhanced transendothelial migratory capacity. Conclusions—TCR dim T cells, an effector T-cell subset with trans...
