We provide a description of each method and the underlying assumptions. We outline advantages and disadvantages as seen by their authors. We hope that this collection provides th...
Three objectives are set for this year: (1) The development and implementation of probabilistic seismic hazard model for multi-sites with consideration of spatial variation of ground motions; (2) The refinement of the methodology to calculate seismic fragility of water supply systems based on a combination of Monte Carlo simulation and hydraulic network analysis for damaged systems; and (3) The...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
A Monte Carlo simulation study of water and hydrocarbons aiming at understanding the degradation of polyethylene cable insulation is presented. Atomistic simulations of water, hydrocarbons and ions are presented. The SPC/E and TraPPE potential functions are used. The equilibrium distributions and clustering of water in vapour and in hydrocarbons was investigated using Gibbs-ensemble Monte-Carlo...
We assume a monopolistic market for a non-durable non-renewable resource such as crude oil, phosphates or fossil water. Stating the problem of obtaining optimal policies on extraction and pricing of the resource as a non-linear program allows general conclusions to be drawn under diverse assumptions about the demand curve, discount rates and length of the planning horizon. We compare the result...
the study investigates consumers’ preference for cowpea reflected in the nigerian markets through price discounts and premiums that consumers pay for different cowpea characteristics. the price data used for this study were obtained through a market survey. a common data collection protocol was employed. every month, between october 2009 to december 2010, five cowpea samples per seller were bou...
Nowadays, transmission pricing is one of the most challenging topics in power systems. Selection a fair price in which emphasizing on returning the cost of transmission networks to owners, and on the other side, would be a fair for users requires considerable study and examination. In transmissions mix approach, a mix of several pricing methods has been used to approach to eliminate the disadva...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Public pricing of products is one of the most important economicalissues, since any changes in the pricing, affects both the welfare ofconsumers and quantity of goods and Services which are produced.In this paper which is done for natural gas pricing in Iran, the purpose is giving a price that the government can consider it as a suitable choice for using in subsidies targeting project. These p...
Price, as an element of marketing, plays an essential role in the decision-making of tourists as well as the income of tourism activists.
