GE was shortest following the HF intervention.
Both methods show no interference concerning the high HF concentration, because the samples are diluted in order to pass the respective measurement ranges of the methods.
Chen and Leung proposed a speech BWE method based on least significant bits (LSB) audio watermark [11], which can embed more HF speech components information but is susceptible to noise and channel interference.
These properties make the use of HF a common pretreatment step for removing paramagnetic interferences and concentrating carbon prior to solid-state 13C NMR spectroscopy with the working assumption that any SOM lost during HF treatment will not bias the resulting NMR spectra.
The most critical point in obtaining accurate Hf isotope data is to correct the isobaric interferences of Yb and Lu imposed on the 176Hf peak.
HF and VHF radio communication are vulnerable to atmospheric interference, thus having blind coverage areas and poor confidentiality.
A hydrofluoric acid (HF) bonding technique for multilayer thin films was studied to fabricate dielectric multilayer interference filters.
In this study, the isobaric interferences of 176Lu and 176Yb on 176Hf were directly estimated by monitoring the intensities of interference-free Lu and Yb signals as the following: 176 Hf measured = 176 Hf + Lu + Yb measured – 175 Lu measured × 176 Lu / 175 Lu true × M 175 / M 176 Lu β Lu – [ 173 Yb measured × 176 Yb / 173 Yb true × M 173 / M 176 Yb β Yb ].
The present study tests the validity of isobaric interference correction at mass 176 by using MC-ICP-MS analysis of Hf standard solutions doped with Yb and Lu.
HF transmissions are able to carry a longer distance than VHF, but are vulnerable to interference and static; VHF is clearer with less interference, and preferred by flight crews.
The cumulative interpretation of the beaming complies well with a Huygens–Fresnel (HF) point of view, where any component of the electric field E Pθ) results from the interference of the direct transmission and the scattering from the grooves at any detection point Pθ in the far field at a distance R0 from the SH and R n from the nth groove; see Figure 1b.
