Interest in the determination and screening of pesticide residues in soil is caused by widespread use of chemical pesticides in agriculture, which increase soil contamination. Two extraction techniques, matrix solid phase dispersion (MSPD) and liquid-liquid extraction (LLE) of residual pesticides (acaricides, insecticides, herbicides, and fungicides) from soil were compared. Advantages and disa...

In our previous comprehensive survey [41], we have categorized the disparate issues in distance metric learning. Within each of the four categories, we have summarized existing work, disclosed their essential connections, strengths and weaknesses. The first category is supervised distance metric learning, which contains supervised global distance metric learning, local adaptive supervised dista...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

For more features massive data sets efficiently reduction problems, to enhance the data uniformity of the near target instance, reduce the errors of represented neighbors, improve the effect of dimension reduction, proposed a dynamic K value method of massive data reduction based on improved LLE algorithm. Utilized the search algorithms based center point, searched an example neighborly, to ens...

Locally Linear Embedding (LLE) [2] and Isomap [1] techniques can be used to process and analyze high-dimensional data domains, such as semantics, images, and colour. These techniques allow creation of low-dimensional embeddings of the original data that are much easier to visualize and work with then the initial, high-dimensional data. In particular, the dimensionality of such embeddings is sim...
