Abstract This paper mainly investigates the multi-user coordinated anti-jamming problem in clustering communication networks.In such kinds of networks, there exist multiple clusters and multiple users who communicate with their receivers ilootpaperie simultaneously.Besides, a malicious jammer persistently attacks channels with wide-band and dynamic
The purpose of the study conducted was an analysis of the influence of pulse density per area unit of LSP on (7277AL Alloy) regarding the surface characterization, roughness achieved and microhardness.The samples, which were used in this investigation, are here 7277Al Alloy.Specify the laser parameter used in this study effect on sample surface pro
We demonstrate the generation, spectral broadening and post-compression of second harmonic pulses using a thin beta barium borate (BBO) crystal on a fused-silica substrate as the nonlinear beetroot birkenstock interaction medium.By combining second harmonic generation in the BBO crystal with self-phase modulation in the fused-silica substrate, we e
