Synthesis of uniform cube shape CuFe2O4 nanoparticles by a hydrothermal method

tailieu.vn

In summary, CuFe 2 O 4 NPs which features with superparamagnetic, and cube shape structure was synthesized by a hydrothermal method. In this study, CuFe 2 O 4 nanoparticles (NPs) which features with superparamagnetic, and uniform cube shape structure was synthesized by a hydrothermal method. The CuFe 2 O 4 NPs were well dispersed with a mean particle size of about 50 nm. The CuFe 2 O 4 NPs is extremely useful for support catalyst in heterogeneous catalysis applications and adsorption..

k-fold cross-validated precision (Prec.) and F 1 score of our proposed method, default SpamAssassin rule set and re-trained default SpamAssassin rule set on English dataset D 2. We carried out this experiment to see how effective this new method is for English spam detection compared to the original method that generated SpamAssassin’s default rule sets. The default, unmodified rule set that comes with SpamAssassin 3.4.2 is used as a baseline for the comparison.

Convergence of Block Decorrelation Method for the Integer Ambiguity Fix

tainguyenso.vnu.edu.vn

In this paper, a new method for integer decorrelation of variance-covariance matrix Q a , which is faster than the method based on the Gauss transformation, will be presented. Therefore, the new method will be named as “Block Decorrelation Method” (BDM) hereafter.. 2 Block Decorrelation Method. the symmetric positive-definite matrix Q a of size n*n is divided into 3 by 3 blocks because of the pre-multiplication by Z k T and post-multiplication by Z k . In Equation (10), it is clear that:.
