Showing papers in "Chemometrics and Intelligent Laboratory Systems in 1986"

TL;DR: Das Programmpaket SAS befindet sich installiert auf einem Rechner des Rechenzentrums (RZ) der Universität für alle Kursteilnehmer notwendig, neben einem gültigen Account auf den rechnern der Fakultät ebenfalls einen gügtigen Account für die Rechners des Rechens zu besitzen.

TL;DR: Shrager et al. as mentioned in this paper used singular value decomposition (SVD) to resolve chemical transitions measured by spectra and resolved using SVD-based data reduction step.

TL;DR: In this paper, Chen et al. showed that the theoretical precision in determining experimental spectral peak parameters (height, width, and position) should depend in a calculable way upon the peak shape, signal-to-noise ratio, and number of data points per line width.

TL;DR: The concept of fuzzy predictions is introduced, which reveals a fuzzy valuation of the predicted concentrations by a membership function rather than associating approximate confidence intervals with the sought concentrations.

TL;DR: Cheng et al. as mentioned in this paper investigated the use of various numerical techniques in the chemical mass balance receptor model, leading to different estimations of mass contributions by the identified sources for an ambient air quality data set.

TL;DR: In this article, the influence of mobile phase modifications on the selectivity of chalcones on an ODS stationary pase has been investigated and the same methods of analysis are used to compare chalcone selectivity in systems with stationary phases of different polarity.

TL;DR: An expert system developed using KES is presented and it is explained how such an expert system was developed and validation results are presented.

TL;DR: The use of Lotus' Symphony software package on a personal computer (PC) can enable a laboratory to easily establish an inexpensive data collection and management system.
