Villages located in Isfahan province are one of the areas prone to the spread of cutaneous leishmaniasis, which is characterized by the occurrence of wounds on the skin. To predict the future prevalence of cutaneous leishmaniasis, Continuous monitoring of the spatial distribution of this disease is essential. Disease modeling was performed using two machine learning algorithms called support ve...
Background: Cone-beam computed tomography (CBCT) scanners for image-guided radiotherapy are in clinical use today, but there has been no consensus on uniform acceptance to verify the CBCT image quality yet. The present work proposed new methods to fully evaluate the performance of CBCT in its three-dimensional (3D) reconstruction space. Materials and Methods: Compared to the traditional methods...
In this paper, we explore the problem of scalable evaluation of Continuous Range Queries (CRQs) with non-spatial selections, each of which continually retrieves the moving objects that (i) are currently within a specified spatial query region and (ii) satisfy specified non-spatial selections. We propose a new query indexing structure, called the Bit-vector Query Region tree (BQRtree), which ena...
Today, soil erosion is considered as one of main subjects of watershed management at national and global levels. Assessment of decreasing risk of soil and it spatial distribution are one of key factors for successful evaluation of soil erosion. The objectives of research were calculation and modeling of rain erosivity factor in Ilam province using data of number of 28 pluviometry stations durin...
Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to eval...
The ornamental and medicinal saffron with high economic value encompasses a great share of non-oil exports in Iran. As a result, identification of suitable areas for saffron cultivation in Ardabil province located in northwestern part of Iran necessitate effective planning for expanding cultivation and production of this product. Given the effect of various environmental factors on growth and y...
Introduction: The present study investigated the role of the Basolateral Amygdala (BLA) N-methyl-D-aspartate (NMDA) receptors in stress-induced spatial memory disturbance among the male Wistar rats. Methods: The male Wistar rats (Average weight =200 g) were cannulated bilaterally in the BLA, and entered the study (n=6-8) after one week. They received seven electro–foot-shock stress sessions o...
abstract this study evaluated and compared medical terminology and english for the students of medicine (ii) as two representatives of the textbooks available on the iranian market for teaching english to the students of medicine. this research was performed on the basis of a teacher’s and a number of students’ attitudes and the students’ needs analysis for two reasons: first, to investigate...
This paper develops a new framework for analyzing the relations among distributions of spatial objects. Existing analytical methods usually focus on the distribution of one or two specific types of spatial objects. This paper, on the other hand, deals with the relations among more than two distributions of spatial objects. The framework is applicable independent of the type of spatial objects. ...
