Determination of the Colorants in Various Samples by Chemometric Methods Using Statistical Chemistry
partial least square and principal component regression methods were applied to various mixtures of Allura Red and Brilliant Blue to determine the concentrations. Colorants, at the same time, were analyzed with UV-spectrophotometry in chemical separation. The obtained experimental data have been evaluated by chemometric methods as Partial Least Squares (PLS) and Principle Component Regressi...
متن کاملDetermination of N-nitrosodimethylamine in environmental aqueous samples by isotope-dilution GC/MS-SIM.
An analytical method for the determination of N-nitrosodimethylamine (N-NDMA) in environmental aqueous samples has been developed using isotope dilution gas chromatography/mass spectrometry in the selected ion monitoring mode (GC/MS-SIM). After deuterated N-nitrosodimethylamine (d6-N-NDMA) as surrogate standard was added to the samples, the analytes were extracted with methylene chloride, dried...
متن کاملInvestigation of Test Automation Data Using Statistical Methods
As the scale of software projects increase, the time allocated to development of software increases that testing of software quality is becoming important depending of this situation. Software test teams take some responsibilities to reduce time of project development and make particular planning to shorten completion of project as well as the time of maintenance. At this point of view, various...
متن کاملOptimal Feature Extraction for Discriminating Raman Spectra of Different Skin Samples using Statistical Methods and Genetic Algorithm
Introduction: Raman spectroscopy, that is a spectroscopic technique based on inelastic scattering of monochromatic light, can provide valuable information about molecular vibrations, so using this technique we can study molecular changes in a sample. Material and Methods: In this research, 153 Raman spectra obtained from normal and dried skin samples. Baseline and electrical noise were eliminat...
متن کاملPrediction of Hurricane Motion by Statistical Methods
Equations for the prediction of hurricane tracks have been developed by use of statistical methods. Data at sea level, 700 mb., and 500 mb. were selected as predictors. Forecasts are prepared in 12-hr. steps for periods up to 48 hr. The forecast equations have been tested on an operational basis during the 1964 and 1965 hurricane seasons. The accuracy of these forecasts compares favorably with ...
