Compared with a conventional single-channel GPR system, a GPR system with a multi-input and multioutput (MIMO) antenna array is not only more efficient in 3D data acquisition, but also allows the collection of a multi-offset dataset, thereby providing additional information for more effective subsurface imaging. We develop a three-dimensional (3-D) reverse time migration (RTM) algorithm for processing...
The performance of speaker verification system (SVS) declines dramatically in noisy environments. To suppress the adverse impact of the noise on SVS, this paper investigates employing the nonnegative matrix factorization (NMF) technique to reconstruct the speech based on the pre-trained speech basis matrix (SBM) and noise basis matrix (NBM). The contribution of this research lies in utilizing the...
A highly efficient spin-polarized electron source is a key element for spintronic devices. One Co-based Heusler alloy in particular, Co2MnSi (CMS), has attracted much interest [1-5] because of its theoretically predicted half-metallic nature and high Curie temperature of 985 K. To fully exploit the half-metallic character of CMS, the effect of defects associated with off-stoichiometry on its half-metallicity...
A Heusler alloy Co2MnSi (CMS) has been extensively studied as a promising spin source material [1,2] because of its theoretically predicted half-metallicity and high Currie temperature of 985 K. We recently demonstrated that the suppression of Co antisites at nominal Mn/Fe sites is critical to obtaining half-metallic quaternary Co2(Mn, Fe)Si (CMFS) [3] in a similar way as in ternary alloy CMS [1,4,5]...
The purpose of this article is to ascertain the characteristic elements of Litchi in Zengcheng city, Guangdong province. Eleven elements in Litchi fruit and soil samples were determined by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES). The content of trace elements in various parts of the fruit and the soil samples and the Biological Absorption Coefficient are analyzed. The characteristic...
With the trend of global economic integration, strengthening economic and trade exchanges between different countries, the economic value of products of designations of origin increased. Fourteen trace elements of soil and plants samples were determined by ICP-AES. The accuracy of method was between 0.76% and 8.46%, and the precision was 0.15%~8.1%, and the detection limits of elements determined...
The purpose of this study is to ascertain the characteristic elements in the Kaempferia Galangal L. Yangchun region, Guangdong province (South China). Thus, fourteen trace elements from soil and plants samples from the place of origin are determined by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES). The correlation of trace elements content between soil and plants and the Biological...
