A fundamental parameters approach to X-ray line-profile fitting
, 1992A convolution approach to X-ray powder line-profile fitting is developed in which the line shape is synthesized from the Cu Kα emission profile, the dimensions of the diffractometer and the physical variables of the specimen.

Fundamental Parameters of B Supergiants
2006To understand the chemical evolution of galaxies, we need a deep understanding of the evolution of massive stars and their role in processing and delivering chemical elements. B-type supergiants represent a substantial population in this context. We present here initial results from non-LTE, line-blanketed stellar atmosphere modelling [1] of a large ...

The X-ray fluorescence (XRF) analysis of geological materials requires a robust analytical method because a large variety of elements to determine can be present in each sample and the concentration range of each one can be very large.

A Fast Algorithm for Fundamental Parameter Calculations
Advances in X-ray Analysis, 1991AbstractA fundamental parameter algorithm for quantitative XFA with characteristic Kα- and Lα-radiations of the specimens is presented. This allows an application to programmable pocket calculators or a fast evaluation of measured countrates for the unknown composition of the specimen by means of PCs. For the practical utilization we need the incidence

Fundamental-Parameters Calculations on a Laboratory Microcomputer
Advances in X-ray Analysis, 1979Fundamental-parameters calculations can be made on a laboratory microcomputer fo r automatic treatment of interelement absorption and enhancement effects in x-ray fluorescence analysis. A new software package, called XRF-11, uses an efficient combination of fundamental parameters and alpha factors to compensate for any lack of measured reference ...

Fundamental Parameters for Seven Be Stars
1998The fundamental parameters (distance, luminosity, temperature, mass) of seven Be stars were determined from a study combining ultraviolet fluxes, Balmer discontinuity parameters, near-infrared observations, and trigonometric parallaxes measured by the Hipparcos satellite.
