From the methods to reduce radar cross section (RCS) such as shaping of the target, radar absorbing material (RAM), and radar absorbing structure (RAS), the RAS composed of frequency selective surface (FSS) screens and low-loss composite materials is used widely because the FSS screen transmits or reflects electromagnetic (EM) waves selectively and the composite material withstands external loads.
It proposes a physical frame composed of frequency domain tiles of five subcarriers with one pilot subcarrier in the middle.
The two main types of nonlinearities were subharmonics, composed of frequency components that are integer fractions of the fundamental frequency, and deterministic chaos, composed of broadband noisy components (see [25]) (Fig. 2, all syllables marked "C").
But perhaps most importantly, we have established that this frequency comb is indeed composed of frequency aliases, and as such is an artifact of the way the genome is converted from a symbolic into a numeric sequence.
In contrast, in stimulus pairs with the opposite sweep direction, the end of the first and the onset of the second tone were composed of identical frequencies, and stronger frequency separation was present only at a longer temporal distance.
The superimposed pressure oscillations during normal-volume spontaneous breathing are composed of several frequencies, allowing the assessment of resistance (R) and reactance (X) at several frequencies simultaneously.
Due to oscillation of vehicle, the guideway is subject to dynamic load composed of different frequencies.
We find evidence that there is strong inter- and intra-sexual conflict within C. remanei, a dioecious species composed of equal frequencies of males and females.
In contrast, the latter situation involves smaller, residual, or metastatic cancer cell populations, composed of high frequencies of resistant variants or dormant cells (Klein et al., 2002).
The impedance diagrams are composed of four frequency domains: at very high frequency (VHF), a Warburg-like behaviour was attributed to the porosity effect of the external part of the oxide layer.
52 The average frequency of urination per day is composed of mean frequency of voluntary and incontinent urination, which represents the severity of frequent micturition and UI, respectively.
