Well placement planning is one of the challenging issues in any field development plan. Reservoir engineers always confront problem that which point should be drilled to achieve highest recovery factor and/or maximum sweep efficiency. In this paper, we use Opportunity Index (ROI) as a spatial measure productivity potential for greenfields, hybridizes reservoir static properties, and brownfields...

We characterize two different approaches to the idea of equality of opportunity. Roemer’s social ordering is motivated by a concern to compensate for the effects of certain (non-responsibility) factors on outcomes. Van de gaer’s social ordering is concerned with the equalization of the opportunity sets to which people have access. We show how different invariance axioms open the possibility to ...

recently, the world health organization has made the need for countries to improve the school context and enhance the health of students at the school in terms of quality of life. this study aimed to determine the relation between improvement, adventure, social solidarity and opportunity with perceived stress among students. during the correlational qualitative research, among the population of...

Hugh Lafollette’s theoretical justification of parental licensing hinges upon consideration of the harms associated with raising children. If we understand Lafollette’s stance as one in which the moral status of children is equal to that of other human beings, we must consider what such a commitment might require of social institutions such as the family. Unlike other licensing programs, I argu...

The school reenrollment probability conditional on a child’s circumstances (gender, indigenous origin, and family background) is our measure of opportunity. For children who completed grades 1–6, we use generalized Lorenz dominance to show that Progresa improved aggregate opportunities reduced inequality Moreover, using the human opportunity index—or, alternatively, Gini aggregator—we decrease ...

We prove a local index formula for cusp-pseudodifferential operators on a manifold with boundary. This is known to be equivalent to an index formula for manifolds with cylindrical ends, and hence we obtain a new proof of the classical Atiyah-Patodi-Singer index theorem for Dirac operators on manifolds with boundary, as well as an extension of Melrose’s b-index theorem. Our approach is based on ...

This study examines the trade-off between the offered rental rate and on-farm and off-farm benefits made by North Carolina farmers during the 15 sign-up of the US Conservation Reserve Program. This program allows farmers to offer a ten year contract for an annual rental rate from the government to remove land from production and put it to a conservation use. Bid acceptance depends on the potent...

background and aim : about one-third of iranian children mortality is caused by injuries from which 36% occur due to road traffic injuries. using child restraint embedded in vehicles can reduce road traffic fatalities by 71% for neonates and 54% for children. based on its effectiveness in reduction of fatality and prevention of injury severity, child restraint usage mandatory law is a priority....
