The phrase "spectrum spectrum" is not grammatically correct and cannot be used in written English.
However, depending on the context, other forms of the word "spectrum" can be used in written English. For example, "The cityscape has a wide spectrum of colors."
It allows zooming, highlighting of regions within the spectrum, spectrum reversal and display of multiple spectra.
Box-counting method was applied to compute multifractal spectrum, spectrum width Δα and spectrum difference Δf of counter surfaces.
A possible manifestation of genesis of fractal dimensions in the system of "spectrum of turbulent pulsations of cosmic plasma – galactic cosmic rays' spectrum – spectrum of atmospheric turbulent pulsations" is analyzed.
It temporarily allows unused portions of the spectrum (spectrum holes/white-spaces), owned by the licensed users (primary users PUs), to be accessed by unlicensed users (secondary users SUs), without causing intrusive interference to the former's communication[1].
Even though many applications still depend on exclusive access to spectrum, spectrum sharing [1 3] is increasingly recognized as the breeding framework for wireless innovation that triggers the development and deployment of more resilient and flexible wireless technologies.
CR entails the temporary usage of unused portions of the spectrum (spectrum holes or white spaces), owned by the licensed users (Primary Users--PUs), to be accessed by unlicensed users (Secondary Users--SUs).
Chroma varied in relation to the contrast in relative brightness in segments of the spectrum; spectra with the strongest differences between reflectance in yellow and blue or red and green (e.g., spectrum 1) gave the highest chroma values.
Among the simulated spectra, spectrum iii is most sensitive to dynamic heterogeneities.
When flash spectra (spectra of the atmosphere during an eclipse) were first obtained, astronomers found several surprising features.
In order to quantify this effect for varying representative spectra, spectra for cloud optical thicknesses from 0 to 150 were investigated.
Sunscreen labels often advertise "full spectrum" or "broad spectrum" properties, meaning that they block both UVA and UVB rays.
