This paper is aimed at deriving the universality of largest eigenvalue a class high-dimensional real or complex sample covariance matrices form $\mathcal{W}_{N}=\Sigma^{1/2}XX^{*}\Sigma^{1/2}$. Here, $X=(x_{ij})_{M,N}$ an $M\times N$ random matrix with independent entries $x_{ij}$, $1\leq i\leq M$, j\leq such that $\mathbb{E}x_{ij}=0$, $\mathbb{E}|x_{ij}|^{2}=1/N$. On dimensionality, we assume $M=M(N)$ and $N/M\rightarrow d\in(0,\infty)$ as $N\rightarrow\infty$. For general deterministic...
Soil hydraulic properties are essential for understanding soil hydrological and erosion processes. The importance of roots on parameters has been widely recognized, but current studies have focused mainly the root effect a single plant species. However, few carried out to investigate mixed parameters. Undisturbed samples were collected from three natural sampling sites with types four types. Both measured: saturated conductivity (Ks) water content (SW). Then effects Ks SW subsequently...
Abstract Removal of phosphorus is a reaction, which plays an important role in combined converter steelmaking process, and the precise control end‐point content during BOF process would greatly improve quality liquid steel. Therefore, relation between dephosphorization ratio temperature steel, FeO slag, slag basicity clearly clarified through thermodynamic analysis this paper. Besides, by means combining methods multivariate regression multi‐level recursive completely, model, used to...
In this study, scanning electron microscopy (SEM), backscatter diffraction analysis (EBSD), and probe microanalysis (EPMA) were used to investigate the impact of rare-earth Sc on interface microstructure mechanical properties Al/steel bimetallic composites fabricated by liquid–solid casting. With addition 0.3% Sc, morphology eutectic Si changed from needle-like fibrous granular. The did not change types intermetallic compounds in reaction layer, which comprised Al5Fe2, τ1-Al2Fe3Si3, Al13Fe4,...
Through analyzing the factors that influence end-point manganese content during BOF steelmaking process, multiple linear regression model for prediction of was obtained on basis actual production data. Given advantages artificial neural network, it used to predict and BP network established. By means combining characteristics genetic algorithm completely, a combined GA-BP The verification comparison above three models show has highest accuracy. hit rate is 90% 84% respectively when...
Dual energy subtraction (DES) radiography is a powerful but underutilized technique which aims to improve the diagnostic value of an X-ray by separating soft tissue from bones, producing two different images. Compared traditional chest X-rays, DES requires exposure higher doses radiation may achieve accuracy. The objective this study was assess clinical benefits comparing speed and accuracy diagnosis pulmonary nodules with versus X-rays.Five radiologists five radiology residents read X-rays...
In order to investigate the effect of shot peening (SP) on residual stress distribution AISI 304 stainless steel, a 3D dynamic model for describing single and multiple impact phenomenon was built via ABAQUS/Explicit 6.10 by considering mesh density treated component as well friction coefficient between validated X-ray measurement. The results show that an optimal surface element size about 1/18th dimple diameter reasonable μ > 0.2 are key factors accuracy estimation computational efficiency....
After high-load spherical indentation treatment, the variations of hardness on plastic zone Ti-6Al-4V were investigated via nanoindentation method. The within center was measured by nanoindenter, and magnitude decreased gradually along depth, which caused different extent deformation under residual imprint. microstructure observed using scanning electron microscope (SEM) before after surface etching, results showed that microhardness revealed average α β phases Ti-6Al-4V. maximum reached...
This paper proposes a multi-grade reactive power utilization evaluation strategy for distribution networks with high renewables to identify the devices low-grade efficiency. Firstly, suitability assessment indicator is presented quantify mismatch degree between demand and compensation capacity in substations, then Kantorovich distance-based scenario reduction method used obtain typical load curves from historical data. Furthermore, influence factors on planning are investigated different...
