Stribeck Curve for Starved Concentrated Contacts
2006This paper discusses a mixed lubrication model in order to predict the Stribeck curve for starved lubricated line contacts. Themodel is an extension of themixed lubrication model of Gelinck and Schipper [1]. In order to build the starved Stribeck curve model, the contact model of Greenwood and Williamson [2] and the EHL film thickness for starved line ...

Light-reflecting concentrators for photomultipliers with curved photocathodes
Applied Optics, 1996Three-dimensional (3D) concentrators for photomultipliers with curved photocathodes have been designed by taking the figures of revolution of ideal two-dimensional (2D) concentrators that are constructed from the 2D profiles of the photocathodes.

Inference on Lorenz and on Concentration Curves
2012In a pathbreaking paper, Atkinson (1970) proved several results concerning the ranking of income distributions according to expected values of all concave social welfare functions. One of the important results is that for distributions with equal means, all social welfare functions show the same order of average social welfares (i.e., the same ordering

Applications of Concentration Curves to Economic Analysis
2022AbstractThis chapter provides many economic applications of the theorems and corollaries developed in Chapter 9. These applications relate to analyzing the relationships among individuals’ or families’ distribution of economic variables. These relationships play a crucial role in understanding many economic phenomena.

Choosing between Concentration Indices: The Iso-Concentration Curve
Economica, 1979It is usual to identify two constituent parts to concentration in any industry: n, the number of firms in that industry and I, the inequalities in the market shares of those firms. For instance, in the conventional structure-conduct-performance models relating industry profitability to the potential for collusion, it is usually argued that collusion ...

Analysis of asymmetry of agonist concentration–effect curves
Journal of Pharmacological and Toxicological Methods, 1999We have developed a fitting procedure, based on nonlinear mixed effect modelling and original work by Richards (1959, J Exp Botany 10, 290-300), to describe the degree of asymmetry of concentration-effect E/[A] curves and analysed the shape of E/[A] curves obtained with alpha1-adrenoceptor agonists in rat aorta.

1937
The discussion of the kinetics of drug action in chapter 11 showed that the rate of action of drugs on living tissues often could be expressed by simple formulae, but that closer examination of the processes involved showed that the processes in most cases were of a complex chain character and that the theoretical significance of the formulae was very ...

Yield Curve and Time-Varying Debt Concentration
SSRN Electronic JournalWe demonstrate the intertemporal behavior of debt concentration by analyzing firms' responses to yield-curve dynamics summarized by the dynamic Nelson-Siegel factors. Firms exhibit countercyclical debt concentration: in bad times, firms increase debt concentration primarily by increasing bank debt and reducing public debt.

Concentration of the sun's rays using catenary curves
Applied Optics, 1978An examination has been carried out of the difficulties a horizontally placed parabola would encounter in concentrating the sun's rays when the angle of incidence between the axis of the parabola and parallel incident rays grows from 0 degrees to 50 degrees .

Concentration dependence curves of cathodoluminescence of Y2O2S:Tb
Applied Physics Letters, 1976It has been demonstrated that the concentration dependence of cathodoluminescence can be explained by a Brownian motion of the energy carriers out of the penetration volume in which they were initially created by the incident electrons. The model predicts several concentration regions and a crystal size effect.
