Dicyanofuroxan is a new and interesting high explosive that can be used instead of some classical explosives. The present density functional treatment considers dicyanofuroxan its ring opened dinitroso isomer. has been based on theory at the level UB3LYP/6-311++G(d,p). Within constraints basis set employed results indicated form electronically more stable thermodynamically favored compared to r...

In this study, we compare the single-carrier (SC) waveform adopted in IEEE 802.11ad and unique word discrete Fourier transform spread orthogonal frequency division multiplexing (UW DFT-s-OFDM) waveform. We provide equivalent representations of up-sampling and down-sampling operations of the SC waveform by using discrete Fourier transform (DFT) and inverse DFT to enable explicit comparison of th...
