We propose simple modifications for the Kakwani tax progressivity measure that make it suitable for evaluating access inequality for medical services. Our modification is to measure inequality using the ratio of the concentration index to the Gini coefficient instead of the difference between them. We also propose a measure using the Gini coefficient or concentration index of consumption expend...
The soil-foundation interaction is one of the most important issues in geotechnical engineering that deals with studying the soil behavior subjected to the side loading. Winkler’s model is the first and simplest method for consideration of the soil-foundation interaction. It is vitally important to determine the coefficient of subgrade reaction of the soil. Since several methods have been prov...
In this study, the elastic bending of sector graphene sheet has been studied based on elasticity using Eringen Nonlocal Elasticity Theory. In order to do this, the balance equations governing the sector graphene sheet have been solved in terms of displacements with regard to nonlocal relationship of stress, shear theory of the first order, and obtained linear strains using developed Kantorovich...
this research develops thermo-elastic analysis of a functionally graded cylinder under thermo-mechanical loadings. heat conduction equation in cylindrical coordinate system is solved. thermal conductivity coefficient is graded along the radial direction. by considering a symmetric distribution of temperature, loading and boundary conditions, strain-displacement and stress-strain relations can b...
Eigenvalue elasticity methods have been widely applied in analyzing linear and simple nonlinear systems. In this study, we applied this approach to gain insight into the leverage offered by parameter changes in individual-based viral dynamic models for studying and controlling infectious disease spread. We found that such eigenspace based methods encounter severe limitations when applied to non...
BACKGROUND The skin score, a subjective assessment of skin elasticity, is widely used in patients with systemic sclerosis. Although this scoring method is regarded as a validated and accepted tool, the interobserver and intraobserver reproducibility is relatively poor. OBJECTIVE Our purpose was to investigate whether the recently developed SEM 474 cutometer, which exerts a controlled vacuum f...
BACKGROUND AND AIMS Real-time shear wave elastography (2D-SWE) is a two-dimensional transient elastography and a competitor as a biomarker of liver fibrosis in comparison with the standard reference transient elastography by M probe (TE-M). The aims were to compare several criteria of applicability, and to assess inflammation and steatosis impact on elasticity values, two unmet needs. METHODS...
This paper seeks to evaluate the effects of expansionary monetary policy by the central bank on inflation, output and employment in a limited-participation model for different parameters value of inter-temporal elasticity of substitution and the Frisch (inverse of the labor supply) elasticity. To this end, a modified cash in advance model in line with Lucas (1990), Christiano (1991) and F...
