In order to determine the effect of climatic factors on distribution of Artemisia aucheri and Artemisia sieberi in Isfahan province, thirty nine most important climatic elements in ecological condition of these species were selected. Using a factor analysis method, the most important factors in distribution of these species were determined. These factors which cover 92.3% of the total variance ...
Like developing countries, our country faces the problem of poverty and the spread of this phenomenon in rural areas and is one of the most important problems in rural areas. Measuring and identifying poverty is an integral part of the knowledge needed to formulate programs and policies for poverty alleviation in society and can be a powerful tool for policymakers' attention to the living condi...
Analysis of large geostatistical data sets, usually, entail the expensive matrix computations. This problem creates challenges in implementing statistical inferences of traditional Bayesian models. In addition,researchers often face with multiple spatial data sets with complex spatial dependence structures that their analysis is difficult. This is a problem for MCMC sampling algorith...
one of temperature estates is hot day occurrence. in order to recognize the mechanism of this estate, surveying its spatial behavior is crucially important. in current paper it has been attempted to recognized widespread hot days and their spatial distribution by using statistical methods. accordingly maximum temperature database of iran during 1962-2008 has been used. the analyses result has i...
ultrasound images suffer of multiplicative noise named speckle. different de-speckling algorithms run either in spatial domain or in transformed domain. in this paper, an adaptive filter in spatial domain according to assume the nakagami distribution as the statistic of log-compressed ultrasound images is used. for de-speckling in transformed domain, the non-sub sampled shearlet transform is us...
Rainfall is one of the most important climatic variables in the hydrology cycle. In flood estimation as well as environmental pollution studies in medium to large watersheds not only mus temporal pattern of rainfall t be known, but also the knowledge of its spatial distribution is required. Estimation of daily rainfall distribution without comparison and selection of suitable methods may lead...
many studies on precipitation trend have been performed in recent years (e.g., brunetti et al., 2006; rodrigo et al., 2007; turkesh, 1996), but spatial analysis of the sign of trends is rarely carried out (suppiah and hennessy, 1998; de luis et al., 2000). in the present paper we analyze the observational precipitation data from some oldest meteorological stations to investigate the possible sy...
nowadays, with the development of human societies and more mastery over the environment, to environmental changes caused by the faster and wider than before the occurrence of the joins. so having the necessary information about these changes and to manage the natural order is essential to sustainable ecosystems, metrics of landscape is tools landscape situation are few mechanisms that cause the...
Background and purpose: The effect of action observation on symmetry of weight distribution and stability indices in semi-dynamic stability in healthy older people is not identified yet. The aim of this study was to investigate the effect of action observation on the symmetry of weight distribution in lower limbs and stability indices in semi-dynamic stability among healthy non-athlete older pe...
The study of the roles and functions of cities and their developments is an important question in modern geographic studies. The unbalanced spatial distribution of populations, irregular migration to metropolises and imbalances in the distribution of economic opportunities between regions have led to focus on the idea of medium-sized cities as one of the most effective approaches to planning ...
