This paper investigates the effect of four driving forces, including elevation, slope, distance to drainage and distance to major roads, on urban expansion in five Saudi Arabian cities: Riyadh, Jeddah, Makkah, Al-Taif and Eastern Area. The prediction of urban probabilities in the selected cities based on the four driving forces is generated using a logistic regression model for two time periods...

â  industrial site selection is a complicated decision and is related to various factors, so it is kind of multi-criteria decision analysis which is used for prioritizing different factors and selecting the best alternative among possible alternatives. in fact by scientific site selection, it is possible to minimize negative impacts of industrial construction and going towards sustainable devel...

Background and objectives: The regionalization is a suitable approach to reduce the cost of health services and to increase the number of patients covered by special services. Since the establishment of the Neonatal Intensive Care Unit (NICU) needs expensive equipment and experts, it is critical to find the optimal number and location for NICU beds and referral networks. <stro...

This paper contains a description of a general class of city formation models. Individual economic agents have preferences for locations that depend upon the population distribution. A location's attractiveness depends upon some combination of its population and its average distance to other agents. Economic variables enter indirectly. Taking this broad perspective leads to a deeper understandi...

In this paper we analyse the profile of land use and population density with respect to the distance to the city centre for the European city. In addition to providing the radial population density and soil-sealing profiles for a large set of cities, we demonstrate a remarkable constancy of the profiles across city size. Our analysis combines the GMES/Copernicus Urban Atlas 2006 land use databa...

Air pollution in industrial cities with emissions from firms is a growing problem in India. Durgapur, one of the growing industrial cities in eastern India, covering a host of industries, suffers from similar problems. The paper estimates the marginal abatement cost of air pollution of industries in Durgapur, West Bengal. We model the technology of a firm with output-distance function. Here the...

In view of the imbalanced distribution of power load and resources, including the status of “electric shortage” in some cities in our country, the article discusses the long-distance transmission technology. It mainly analyzed two ways of the long-distance transmission: UHV AC transmission and UHV DC transmission. The fractional frequency transmission technology and half wavelength AC transmiss...

We propose a new polynomial-time deterministic algorithm that produces an approximated solution for the traveling salesperson problem. The proposed algorithm ranks cities based on their priorities calculated using a power function of means and standard deviations of their distances from other cities and then connects the cities to their neighbors in the order of their priorities. When connectin...
