inrtoduction developing countries and newly industrialized countries face the twin challenges of protecting the environment while also strengthening their economies. over the past few decades, the intensified process of urbanization and industrialization undertaken by these countries, coupled with rapid population growth, has resulted in the degradation of the environmental quality. particularl...

We analyze the comparative static effects of beneficial changes in the dependence structure between risks. In a quasi-linear decision model with an endogenous risk and a dependent background risk, a mean-variance decision maker will choose a lower level of risky activities upon an increase in the coefficient of correlation of the risks if, and only if, the elasticity of risk aversion is larger ...

The effect of frequency content on the dynamic response of concrete gravity dams is investigated in this paper. Dams are one of the most complex structures to handle when there is dynamic analysis involved. One of the influential parameters on these structureschr('39') seismic response is the frequency content of the earthquakes. An index to represent frequency content, which represents frequen...

-In this paper, an attempt has been made to establish a market mechanism for primary and secondary frequency regulation services in the restructured power system environment. The concept of elasticity of offer price and elasticity of offer quantity has been proposed. Such a design of offer structure helps the providers to respond to the system requirements based on the market price variations i...

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...

Stabilized mixes are used in the construction of bearing layers in asphalt and concrete pavement structures. Two nondestructive methods: resonant frequency method and ultrasonic pulse velocity method, were used for estimation of elastic properties of fly ash-stabilized mixes. Stabilized mixes were designed containing sand from the river Drava and binder composed of different share of cement and...

PURPOSE The biomechanical properties of the cornea have an important role in determining the shape of the cornea and visual acuity. Since the cornea is a nonhomogeneous tissue, it is thought that the elastic properties vary throughout the cornea. We aim to measure a map of corneal elasticity across the cornea. METHODS An acoustic radiation force elasticity microscope (ARFEM) was used to creat...
