Electroplated rhodium foil was employed as the target for cyclotron production of palladium-103. An electrodissolution apparatus was found better than other dissolution methods in terms of personnel shielding and palladium-103 yield. The ion-exchange column chromatography method was simple and effective for the purification of palladium-103 and the final stripping agent of NH4Cl + NH3(1:1) was ...

Recently, there has been an increased attention in the literature on the use of ensemble methods in multivariate regression and classification. These methods have been shown to have interesting properties both for regression and classification. In particular, they can improve the accuracy of unstable predictors. Ensemble methods have so far, been little studied in situations that are common for...

Aboveground biomass (AGB) is one of the strategic biophysical variables of interest in vegetation studies. The main objective of this study was to evaluate the Support Vector Machine (SVM) and Partial Least Squares Regression (PLSR) for estimating the AGB of grasslands from field spectrometer data and to find out which data pre-processing approach was the most suitable. The most accurate model ...

Visible and near infrared spectroscopy (VIS-NIR) is increasingly being transferred from laboratory to industry for in-line portable applications in various domains. By intensively using VIS-NIR spectroscopy, some abnormal observations may certainly arise. It then important properly handle outliers elaborate effective prediction models. The objective of this study investigate the potential a rob...

With the development of mid-infrared (MIR) photoelectric devices, spectroscopy has become one important methods for non-invasive detection blood glucose. The region (4000 - 400 cm-1) well-known fingerprint (1200 800 glucose, which clearer characteristic absorption peaks and better specificity. There is a lot molecular information about glucose in MIR. by needs to achieve certain accuracy, quant...

In this paper, the variation transmission model is introduced to build the key quality characteristics identifying model in multistage manufacturing process. Then the PLSR (Partial Least Squares Regression) method is used to solve the multicollinearity problem of the quality characteristics, make model analyzing and identify the key quality characteristics. At last, the aircraft parts manufactu...

Many actual multistage manufacturing processes are not serial structure, but parallel structure or hybrid structure. The quality relationship model for multistage manufacturing process with parallel structure was developed based on state space model. The quality relationship model of multistage manufacturing process with hybrid structure was developed via the hierarchical iteration method based...
