AA. Despite the breadth of IR bands, the IR spectra of molecules are so complex that no 2 compounds with different structures have the same IR spectrum except for optical isomers and certain high molecular weight polymers differing only slightly in molecular weight. IR spectrometers are scanning ...

In general, the plasma is optically thin, and the discrete radiation spectrum is in strong non-Boltzmann equilibrium. The dominant spectral features will depend on the gas chemical composition and pressure, as well as the temperature (derived from the shock velocity). Entries faster than 7 km/s...
where 𝑉𝑅VR and 𝑉𝐻VH denote the ranges of respiratory and heartbeat frequencies, respectively; 𝑓𝑝fp is the peak index bin; 𝑃𝑥(𝑓)Pxf is the spectrum of vital sign, and the peak range is defined as 𝐵B. To evaluate the error, the following definition is made. ...

Blooming was continuous with its peaks in June and August 2015. All selected plants for morphological analysis presented a uniform and identical flower coloration pattern to the plants that were initially selected. To carry out SRAP and FT-IR analyses, one individual (propagated by leaf cuttings) ...
especially in dealing with a periodogram with multiple similar peaks, breaking through the premise that the frequency corresponding to the maximum peak is the correct frequency, and validated in two different environments. The experimental results show that the proposed method can improve the accuracy ...
