Iterative substructuring methods with Lagrange multipliers for the elliptic system of linear elasticity are considered. The algorithms belong to the family of dual-primal FETI methods which was introduced for linear elasticity problems in the plane by Farhat et al. [2001] and then extended to three dimensional elasticity problems by Farhat et al. [2000]. In dual-primal FETI methods, some contin...

We examine the influences of urban redevelopment costs and land-use allocation efficiency and equity on the elasticity of housing development density with respect to urban demand shocks in the context of China’s urban growth from 1998 to 2004. We do so in an inter-city spatial equilibrium framework, where demand shocks are capitalized in urban land rent growth, which influences urban population...

Nanotechnology is one of the pillars of human life in the future. This technology is growing fast and many scientists work in this field. The behavior of materials in nano size varies with that in macro dimension. Therefore scientists have presented various theories for examining the behavior of materials in nano-scale. Accordingly, mechanical behavior of nano-plates, nanotubes nano-beams and n...

Atomic force microscopy provides a novel technique for differentiating the mechanical properties of various cell types. Cell elasticity is abundantly used to represent the structural strength of cells in different conditions. In this study, we are interested in whether physical or physiological cues affect cell elasticity in Atomic force microscopy (AFM)-based assessments. The physical cues inc...

Elastic materials are ubiquitous in nature and indispensable components in man-made devices and equipments. When a device or equipment involves composite or multiple elastic materials, elasticity interface problems come into play. The solution of three dimensional (3D) elasticity interface problems is significantly more difficult than that of elliptic counterparts due to the coupled vector comp...

the main purpose of this study was to determine the factors affecting the export of flowers in iran. after data collection using by the index of revealed comparative advantage (rca), the condition of business of flowers in iran was compared with a number of countries exporting the product. according to the results of study, the small elasticity of the exportation price in the function of export...

price is one of the four elements of marketing mix. one of the important decisions any business faces is select pricing strategies that can be effective in achieving company goals. pricing methods are generally divided into cost-based and value-based methods. considering that the marginal cost of information goods is zero, the pricing methods of these goods is value-based. in this study, mtn ir...

BACKGROUND Exposure to risk factors in childhood may have long-term influences on vascular function. We examined the relationship between risk factors identified in childhood and arterial elasticity assessed in adulthood. METHODS AND RESULTS Carotid artery compliance (CAC), Young's elastic modulus (YEM), and stiffness index (SI), 3 measures of large-artery elasticity, were assessed with nonin...
