Recent researches have shown that grid resources can be accessed by client on-demand, with the help of virtualization technology in the Cloud. The virtual machines hosted by the hypervisors are being utilized to build the grid network within the cloud environment. The aim of this study is to survey some concepts used for the on-demand grid provisioning using Infrastructure as a Service Cloud an...

Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for impr...

we have studied the relation between bank deposit rates and house prices in iran. for that, we have run some var models, using the following variables: real deposit rates (including 1 and 5 years deposit rates), money supply (including the high powered money and the liquidity), gdp, housing services index, and number of licenses for new houses. our results show that a reduction in the deposit r...

Many forecasting techniques have been applied to sales forecasts in the retail industry. However, no one prediction model is applicable all cases. For demand of same item, different results models often confuse retailers. large companies with a wide variety products, it difficult find suitable for each item. This study aims propose dynamic selection approach that combines individual and combina...

this paper develops positive mathematical programming (pmp) model to determine the optimum cropping pattern and water demand function in six regions of lower part lands of shirindarre dam in north khorasan province of iran and then estimates the expected pay for water in each region. the quantity of water supplied from such different water resources as dams, wells, and rivers in different scena...

due to increasing number of international tourists and the enhancing role of tourism in economies of countries and competing environment, recognizing determinants in attracting international tourists seems very essential than ever before. public and private sectors need to examine determinants and forecast tourism demand. the primary aim of this study is using econometric techniques to analyzin...

Understanding of energy consumption patterns is extremely important for optimization of resources and application of green trends. Traditionally, analyses were performed for large environments like regions and nations. However, with the advent of Smart Grids, the study of the behavior of smaller environments has become a necessity to allow a deeper micromanagement of the energy grid. This paper...

The intermittent demand forecasting problem involves the forecasting of demand series that are characterized by the time between demands being significantly larger than the unit of time used for the forecast period. This causes the time series associated with the demand to have a large percentage of periods for which there are no demands. These types of series are often found in spare parts inv...
