Urbanization changes have been widely examined and numerous urban growth models have been proposed. We introduce an alternative urban growth model specifically designed to incorporate spatial heterogeneity in urban growth models. Instead of applying a single method to the entire study area, we segment the study area into different regions and apply targeted algorithms in each subregion. The wor...

Simulating complex natural or social systems often implies to consider entitites at several levels of organisation, and take into account the way they influence each other. The choice of scales is driven by both methodological and thematic constraints which among others include the objects of significiance for the specialists, availability of relevant data for comparison, question of interest a...

the blending of nr and br rubber blend with n330 carbon black is studied on curing behavior and the physico-mechanical properties of a sbr rubber based tire tread compound containing n234 carbon black. the effect of sulphur and accelerator contents on different properties of rubber compound is also tested with a wide range of curing agents. partial substitution of sbr with nr shows significant ...

in this study myer index was calculated for six groups of a sample of urban and rural population of iran, classified by population size. the data used were information collected on 146116 urban and 158124 rural populations, for estimation of death, birth and growth rates in iran. the results indicate: the range of the index varies between 23.14-68.06 for women and 28.41-69.62 for men (urban or ...

Coastal cities in China are challenged by multiple growth paths and strategies related to demands in the housing market, economic growth and eco-system protection. This paper examines the effects of conflicting strategies between economic growth and environmental protection on future urban scenarios in Ningbo, China, through logistic-regression-based cellular automata (termed LogCA) modeling. T...

Land use changes result from population growth and migration of poor rural people to urban areas for economic opportunities. Changes in land use directly influence the regional air quality, energy consumption and climate at global, regional and local scales. Controlled, coordinated and planned urbanization is a gift to the human society. However, unplanned urbanization can be a disaster. Urban ...

Urbanization is one of the great challenges of our time and unchecked haphazard urbanization is a serious threat both to the environment and social and economic balance. In order to meet global sustainability targets, rapid urban growth must be channelled into environmentally friendly, sustainable and liveable urban environments. Thus, this special issue focuses on sustainable urban design whic...

in our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. the objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). the urban form design will bediscussed through the simulation of airflow by using computation...

the shape of urban development and its impact on economic growth is one of the most important issues in urban economic literature. in accordance to the corresponding theory, economic growth and urban concentration have an inverse-u shape relation. the shape of urban development is related to how resources are spread out in existing cities of an urban system and investigated under the term of ur...
