The behavior of many physical processes is greatly aaected by some of their localized physical properties. For such cases it is essential that local grid reenement techniques be applied. We present the results of implementation of four local error indicators, namely the residual based error indicator, an error indicator based on the approximation of the second derivatives, Zienkeiwicz-Zhu error...

Various evolutionary multiobjective optimization algorithms (EMOAs) have replaced or augmented the notion of dominance with quality indicators and leveraged them in selection operators. Recent studies show that indicator-based EMOAs outperform traditional dominance-based EMOAs. Many quality indicators have been proposed with the intention to capture different preferences in optimization. Theref...

Life Cycle Assessment (LCA) is the study of the environmental impact of products taking into account their entire life-span and production chain. This requires gathering data from a variety of heterogeneous sources into a Life Cycle Inventory (LCI). LCI preparation involves the integration of observations and engineering models with reference data and literature results from around the world, f...

Rodent baits containing systemic insecticides are potential tools to interrupt the cycle of transmission of Leishmania parasites by killing sand flies that take bloodmeals from rodents as adults. Bio-indicators that can be used in conjunction with rodent-targeted sand fly control methods also have been developed to demonstrate that the insecticide treatments are reaching the targeted life stage...

purpose: the distinction between the concepts of science and technology has made it necessary for economic and scientific policymakers to know the realms of these two areas. the relationship between the science and the technology is changing and also is variable depending on the circumstances, scientific areas, and from one time to another one. the current research aims at studying the growth t...

Previous work by Tesser (1993) and Bourgeois (2002) found that heritable attitudes are more resistant to social influence and attitude change. The present study sought to replicate and extend previous work by utilizing attitudes and heritability estimates not previously used in studies examining the effect of heritable attitudes on social influence processes. It was hypothesized that attitudesw...

Poverty analysis is often based on national level indicators that are compared over time or across countries. The broad trends that can be identified using aggregate information are useful for evaluating and monitoring the overall performance of a country. For many policy and research applications, however, the information that can be extracted from aggregate indicators is not sufficient. Resea...
