Demodulation and decoding are pivotal for the eLoran system’s timing information transmission capabilities. This paper proposes a novel demodulation algorithm leveraging multiclass support vector machine (MSVM) pulse position modulation (PPM) of signals. Firstly, existing method based on envelope phase detection (EPD) technology is reviewed, highlighting its limitations. Secondly, detailed exposition MSVM presented, demonstrating theoretical foundations comparative advantages over...
The coexistence of arsenic (As) and other salts in high concentrations groundwater northwest China restricts its use as a drinking water supply source. behavior negatively charged membrane nanofiltration (NF) at pilot-scale was investigated over the simultaneous removal As salinity from synthetic solution. parameters that affected rejection As(V) were studied; include pH temperature feed, applied pressure, natural organic matter (NOM), presence different feed. Meanwhile, fouling cleaning...
<title>Abstract</title> Dissolved organic carbon (DOC) is an indispensable component of the global cycle and potentially affects aquatic ecosystems. Previous research on runoff process DOC loss mainly focused surface flow, with few reports hydrological pathway interflow or via interflow. To address this deficiency, a series rainfall simulations were conducted three intensities 60, 90, 120 mm h<sup>− 1</sup> (R60, R90, R120) slope gradients 5, 15, 25° (S5, S15, S25) purplish soil. The initial...
In the field of modern navigation and positioning, ground-based eLoran system, serves as a vital backup to global satellite system (GNSS), which is crucial for numerous key applications. Signal demodulation, integral eLoran’s precision timing information transmission, significantly affects performance. Aiming at pulse position modulation (PPM) characteristics signals, this paper introduces an innovative phase spectrum smoothing demodulation (PSSD) algorithm, crafted improve performance under...
The objective of this study was to determine the distribution cadmium (Cd) accumulation in tobacco and identify relationship between soil properties plant Cd concentration. Forty samples were collected from Sichuan Basin, China (Panzhihua, Luzhou, Guangyuan Yibin). results showed highest (2.94 mg kg−1) Yibin. Correspondingly, concentrations Yibin significantly higher than those other regions. Yibin, Panzhihua 2.22 13.14, 0.59 2.12, 0.26 0.61, 0.10 0.37 kg−1, respectively. leaves stems roots....
