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...

This paper presents an estimate of the price elasticity of supply for tobacco output in Zimbabwe using an adapted Nerlovian model. The results indicate a short-run elasticity of +0.34 and a long-run elasticity of +0.81, suggesting that tobacco farmers are highly unresponsive to price changes. These estimates are similar to those obtained for tobacco in supply response studies conducted in other...

In the database area, elasticity of cloud computing has required data systems to increase and decrease their resources on demand. However, traditional benchmark tools for data systems are not sufficient to analyze some specificities of these systems in a cloud. New metrics for elasticity are needed to provide an indicator both from consumer and provider perspective. In this work we present a se...

Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal con...

For classical elasticity, the constitutive equations (Hooke’s law) have the same functional form for both homogeneous and nonhomogeneous materials. However, for straingradient elasticity, such is not the case. This paper shows that for strain-gradient elasticity with volumetric and surface energy (Casal’s continuum), extra terms appear in the constitutive equations which are associated with the...

The analysis of collusion in infinitely repeated Cournot oligopoly games has generally assumed that demand is linear, but this note uses constant−elasticity demand functions to investigate how the elasticity of demand affects the sustainability of collusion.

"Elasticity" in bakery is a sensory perception that is felt when the dough is rapidly stretched and released. Elasticity is good when the dough contracts rapidly to approximately its original shape. In another test the baker tries to stretch the dough into a thin membrane (Fig. 82). The formation of membranes with no fissures is attributed to good gluten quality 14 The Role of Gluten Elasticity...

Elasticity imaging is emerging as an important tool for breast cancer detection and monitoring of treatment. Viscoelastic contrast in lesions is generated by disease specific processes that modify the molecular structure of connective tissues. We showed previously that gelatin hydrogels exhibit mechanical behavior similar to native collagen found in breast tissue and therefore are suitable as p...
