Building upon the concept of utilizing quasi-parabolic approximations to determine plasma frequency profiles from ionograms, we present a refined multi-quasi-parabolic method for modeling the E and F ...

Abstract: The inversion algorithm attracts much attention since it converts surface potential to the distribution of surface charges on solid insulation. The surface charge inversion algorithm for ...

To meet the requirements of single-angle and multi-band polarization aerosol detection, a research team led by Professor SUN Xiaobing from Anhui Institute of Optics and Fine Mechanics, Hefei ...

Abstract: In order to deal with the inverse problem in aperture synthesis radiometers (ASRs) imaging, some deterministic inversion algorithms are proposed. However, these inversion algorithms are ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

In recent years shallow gas blowouts have occurred several times in Balikpapan residential areas due to drilling activities for groundwater exploration and geological structures that play as a gas ...

An eye-safe 1.5μm visibility lidar is presented in this work considering in situ particle size distribution, which can be deployed in crowded places like airports. In such a case, the measured ...

Surface waves have proven to be valuable instruments in subsurface investigation, finding applications in diverse fields such as hydrocarbon and mineral resource exploration. The computation of ...
