in recent years, the studies of location play a key role in success and stability of economic activities. location studies are under consideration in both national and international levels. meanwhile, identification of goals and methods of solving location problems have significant importance. the purpose of this paper is to examine spatial distribution of economic activities in 14 zones of esf...
in recent years, space syntax theory has been used for analyzing spatial configurations; these analyses mostly focus on social aspects. according to the space syntax theory, space arrangements affect the space usage in buildings. this paper aims at studying spatial configurations of some traditional houses in iran in terms of flexibility factor. besides of having the housing function and provid...
Abstract With the rapid growth of population and urbanization since the last century, the complexity and understanding of the spatial organization of the city, as well as the ability to predict urban events in its spaces, have become difficult and in some cases impossible. Karaj metropolis is one of the major metropolitan areas of Iran that has been experiencing rapid population growth and thi...
Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...
Dust is influenced by the interaction of the atmosphere-Earth system and, by changing radiation energy, atmospheric chemistry and physics, affects the climate of an area. Due to the necessity of the role of dust and its spatial-dynamic distribution in the atmosphere of a region, as well as the existence of advanced remote sensing techniques and modeling in the field of dust simulation, the pres...
Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...
To investigate the spatial error correlation in panel regression models, various statistical hypothesizes and testings have been proposed. This paper, within introduction to spatial panel data regression model, existence of spatial error correlation and random effects is investigated by a joint Lagrange Multiplier test, which simultaneously tests their existence. For this purpose, joint Lagrang...
Spatial pattern of trees in forests reveals how trees interact with each other and their environment. Spatial structure of trees in forest ecosystems is affected by environmental heterogeneity that leads to their heterogeneous distribution. This study was aimed to investigate the appropriate methods to analyze spatial pattern of heterogeneous wild pistachio woodlands in Zagros, Iran. A 40-ha pu...
Introduction and Background: With the ever-increasing superiority of neoliberalism views and decreasing government investments in public affairs since the 1980s, the functional and ownership roles of the government have been reduced. These functions replaced by the actively growing roles of corporations and nongovernmental institutions in space development and management. For instance, the inde...
One of the major issues examined in the quantitative ecology is the spatial distribution pattern of plant species. Knowledge of the spatial distribution patterns is essential to measure the level of uniformity in the surrounding environment, plant reproduction, and distribution of the seedlings, plant behavioral patterns, coexistence, allelopathic relations, and competition. Therefore, the aim ...
