Considering the great application of Sea Surface Temperature (SST) in climatic and oceanic investigations, this research deals with the investigation of spatial autocorrelation pattern of SST data obtained from AVHRR sensor for Gulf of Oman from 2003 to 2015 (13 years). To achieve this aim, two important spatial statistics, i.e. global Moran and Anselin local Moran’s I were employed within mont...
introduction precipitation plays an important role in the global energy and water cycle. it is important for assessment and management of land use, agriculture and hydrology such as flood and drought risk reduction to know about the amount of precipitation reaching the ground water. assessment of climate change and its effects require long-term rainfall analysis in all spatial scales. growing c...
Introduction This survey is based on deciphering the space of globalization phenomenon and revealing affected by spatial actions mechanism under investment discipline (according to compressed space and time). The basic question is how the space could be used, organized and created so that it could be in line with investment flow progress necessities. This can be unrevealed by applying concep...
owledge of spatial rainfall behavior in environmental, land planning is effective. These changes in the later place in the form of time later and in the climate of the area. The Target of this study was to reveal the presence or absence of precipitation trend in the ratio of the height of local precipitation behavior and identify province mazandarn. Therefore, the purpose of the rainfall data s...
introduction in 1950s, only 30% of the world's population lived in urban areas. by 2000, that proportion increasedup to 47%, and by 2050 the estimated number will be around 72%. urban sprawl, an undesirable type of urban growth, is one of the major concerns ofthe city planners and administrators. understanding urban patterns, dynamic processes, and their relationships is a primary objectiv...
In recent years, due to the increased population, urbanization and changes in human consumption patterns, urban, industrial and agricultural soils have been exposed to various pollutants such as heavy metals. The objective of this research was to identify hotspots of Pb by using global and local Moran Indices in urban and suburban soils of Kashafrood catchment. A total of 261 surface soil sampl...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
1. introduction drought is one of the most complex problems not only in the management of water resources, but also creates economic and social issues . but the problem definition, identification and prediction of unresolved. the occurrence of drought can be caused by several factors, mainly rooted in the general circulation of the atmosphere and space physics, and earth's energy balance is sou...
Today, with the development of paradigms such as the compact city, smart growth and new urbanism, mixed land use-as one of principles of this paradigm- has been expanded in urban planning of developing countries and various researchers tried to develop literature and assessment methods of land use based on the concept of mixture of land use. The conc...
Spatial synchrony, that is, correlated population fluctuation over wide geographical areas, has been detected in diverse taxa and over various geographical scales. The most commonly suggested mechanisms to explain spatial synchrony include dispersal and regional stochasticity (i.e., “the Moran effect”). We analyzed landscape-scale historical outbreak data for six forest insect species: spruce b...
