Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

This paper argues that Vidya (education), Veda (religion) and Varna (caste) are inter-linked in India. It examines whether, and to what extent, the enrolment of children at school in India is influenced by community norms such those of religion (Hindu or Muslim) or caste (Scheduled or nonScheduled). The econometric estimates are based on unit record data from a survey of 33,000 rural households...

this paper seeks to understand the role of the cost of pollution from vehicles fuel in feasibility of cng national plan. optimal control theory is used with two target functions, one with and another without the cost of pollution. model results indicate the high importance of pollution cost in the project feasibility, in such a way that without consideration of that the project will be infeasib...

This paper presents an economic evaluation of gas to liquids (GTL) project using “South-Pars” gas field of Iran based on the latest actual performing GTL projects. Iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of GTL products which have lower pollution and higher quality than refinery products. The results of cost-benefit analysis sho...

This work is devoted to the study of a viscous shallow-water system with friction and capillarity term. We prove in this paper the existence of global strong solutions for this system with some choice of large initial data when N ≥ 2 in critical spaces for the scaling of the equations. More precisely, we introduce as in [14] a new unknown,a effective velocity v = u+μ∇ lnh (u is the classical ve...
