Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...

Aperodic (or called Golay)/Periodic complementary pairs (GCPs/ PCPs) are of sequences whose aperiodic/periodic autocorrelation sums zero everywhere, except at the shift. In this paper, we introduce GCPs/PCPs over quaternion group \begin{document}$ Q_8 $\end{document}, which is a generalization quaternary ...

Heat transfer by electromagnetic radiation is one of the common methods of energy transfer between objects. Using the fluctuation-dissipation theorem, we have studied the effect of particle arrangement in the transmission of radiative heat in many-body systems. In order to show the effect of the structure morphology on the collective properties, the radiative heat transfer is studied and the re...

Filter structures for interpolation and decimation with factors of two are introduced. The structures are derived by using the frequency-response masking approach, in which the overall Þlter is composed of a periodic model Þlter, its complementary periodic Þlter, and two masking Þlters. The model and complementary model Þlters consist of two allpass Þlters in parallel, whereas the masking Þlter...

We exploit the mirror and complementary symmetries of elementary cellular automata (ECAs) to rewrite their rules in terms logical operators. The operator representation based on these fundamental enables us construct a periodic table ECAs that maps all unique clusters similar asymptotic behavior. also expand automaton (ECA) dynamics by introducing parameter scales pace with which operators iter...
