They are made by holographic recording in a photo-polymerization induced phase separation process (PIPS) in which the liquid crystal molecules diffuse to dark zones in the

For the second case of this study, the features for training the SVM will be extracted from the brain sources estimated using the selected SLMs MLE, MNE and wMNE. The scenario is

Only a few of the studies made of the extraction of compounds from river water samples were developed in the on-line mode because the mobile phase used was the same as

The photometry of the 236 238 objects detected in the reference images was grouped into the reference catalog (Table 3) 5 , which contains the object identifier, the right

Different methods for removing interference by humic substances in the analysis of polar pollutants have been compared in the analysis of environmental water by solid-phase

Finally, with regard to research question 2, a factor analysis was applied in order to identify a likely combination of the on-line creative strategies used by the

Three sample treatment methods, based on QuEChERS, solid-phase extraction (SPE) and solid-phase microextraction (SPME), were compared and evaluated in order to obtain the
