Aghayan K.L On stress concentrators like stringers and cracks in an infinite plate and strip ................................... 5 Several works related to the contact and mixed problems of the theory of elasticity, which explores issues of mutual influence of two types stress concentrators in an infinite plate and strip are presented. Due to appropriate choice of the relative location of the s...

− The constitutional diagnosis using human skins is classified to palpation in oriental medicines. From Sasang constitutional medicine which is one of oriental medicines, human could be divided by the properties of their skins such as texture, roughness, hardness and elasticity. Especially, the friction coefficient and roughness of skins have big discrimination ability in the classification of ...

We study a one-dimensional gas of needlelike objects as a testing ground for a formalism that relates the thermodynamic properties of "hard" potentials to the probabilities for contacts between particles. Specifically, we use Monte Carlo methods to calculate the pressure and elasticity coefficient of the hard-needle gas as a function of its density. The results are then compared to the same qua...

Analysing a large sample of 1980–2004 unbalanced panel data, the current study presents comparative global evidence on the role of (income) inequality in poverty reduction. The evidence involves both an indirect channel via the tendency of high inequality to decrease the rate at which income is transformed to poverty reduction and the tendency of rising inequality to increase poverty. Based on ...

Objective. Test-retest reliability of the myotonometer was investigated in patients with subacute stroke. Methods. Twelve patients with substroke (3 to 9 months poststroke) were examined in standardized testing position twice, 60 minutes apart, with the Myoton-3 myometer to measure tone, elasticity, and stiffness of relaxed bilateral biceps and triceps brachii muscles. Intrarater reliability of...

Numerical simulations of PTT fluids in axisymmetric sudden contractions were carried out to investigate the effect of contraction ratio on the flow patterns under conditions of negligible inertia. The PTT model selected has a linear stress coefficient, and contraction ratios (CR) in the range 4:1 to 100:1 were investigated. The simulations are based on a finite volume methodology using very fin...

This work introduces a new approach to fake finger detection, based on the analysis of human skin elasticity. When a user puts a finger on the scanner surface, a sequence of fingerprint images which describes the finger deformation process is captured. Then two features which represent the skin elasticity are extracted from the image sequence: 1) the correlation coefficient of the fingerprint a...

Objectives. The study seeks to provide comparative global evidence on the role of income inequality, relative to income growth, in poverty reduction.Methods. An analysis-of-covariance model is estimated using a large global sample of 1980–2004 unbalanced panel data, with the headcount measure of poverty as the dependent variable, and the Gini coefficient and PPP-adjusted mean income as explanat...
