Concentration curves in atomic absorption spectrometry
Spectrochimica Acta Part B: Atomic Spectroscopy, 1992A detailed analysis of the correlation between the number of absorbing atoms, N, and the absorbance, A, produced by them, i.e. A = f(N), is given. This analysis is valid for any optical thickness of the absorbing layer and accounts for Doppler broadening and pressure broadening of the emission and absorption lines, hyperfine structure and collisional ...

On The Behaviour of the Z p Concentration Curve
1990Since M. Zenga introduced in 1984 his point concentration measure Z p , based on the ratio between population and income fractiles, and the synthetic measure ζ, which is the espected value of Z p (Zenga, 1984), several authors have been interested in the analyses of the characteristics and properties of these measures.

Concentration Curves And Concentration Indexes Derived From Them
1990Many synthetic concentration measures are derived from concentration curves. The ordinate of the concentration curves may be utilized as point concentration measure (local concentration). In this paper, after having analysed the behaviour of the concentration curves derived from the Lorenz curve and the behaviour of the Z(p) curve, the formal ...

Concentration on curves for nonlinear Schrödinger Equations
Communications on Pure and Applied Mathematics, 2006AbstractWe consider the problem where p > 1, ε > 0 is a small parameter, and V is a uniformly positive, smooth potential. Let Γ be a closed curve, nondegenerate geodesic relative to the weighted arc length ∫Γ Vσ, where σ = (p + 1)/(p − 1) − 1/2.

Measuring concentration: Lorenz curves and their decompositions
The Annals of Regional Science, 2010This paper first reveals the basic properties behind the relative concentration measurement when using employment Lorenz curves. This involves axioms adapted not only from the literature on income distribution, but also from that on occupational segregation.

Determination of High Concentrations with Calibration Curves
1972The fluorescent intensity of a component is, in a first approximation, proportional to the concentration. The precise composition is determined with the aid of standard samples. For mixtures consisting of two and three components, the graphical method of determining the concentration is commonly used.
