The purpose of the current research is to measure and evaluate the distribution of urban services in the 51 districts of Ardabil city. The research method is descriptive-analytical based on documentary sources and a questionnaire to collect public opinions. For this purpose, 385 questionnaires have been completed and collected from urban areas using a random classification method. To analyze the data the VIKOR model was used in which the following were considered: determination of the weight of 11 main research indicators using the opinions of 10 experts (through the snowball method) and the entropy method using. The findings of the research show that the central areas of the city are at a favorable level in terms of access to urban services, and the more the distance from the city center to the periphery, the lower the level of favorability. Also, the results of the cluster analysis showed that the urban areas located in the center of the city are on the first floor and the peripheral areas are on the last floor (i.e. the fifth floor). Also, comparing the results of objective data (distribution of services) and subjective data (citizens' questionnaire) showed that there is a significant statistical difference between them. In fact, considering the objective results, the subjective results are far from the facts and the people's emotional opinions mostly prevail. The result is that the urban services of Ardabil are not distributed based on spatial justice and the dominant pattern of distribution is cluster like and center-peripheral.

The purpose of this research is to compare the efficiency of Pixel-Based kernel functions on the support vector machine algorithm and Object-Based fuzzy operators in the extraction of built-up land in Hamedan. For this purpose, the Sentinel 2 satellite multi-spectral image with a spatial resolution of 10 meters has been used. ENVI software was used for image preprocessing and Pixel-Based classification, and eCognation software was used for Object-Based classification. In the processing stage, first, in the ENVI software environment, training data and ground truth points were determined, and then using support vector machine kernel functions, including linear, polynomial, radial, and sigmoid basis functions, the class process The pixel-based classification was done and then the classification accuracy of the pixel-based method was evaluated. In the environment of eCognation software, segmentation operation was done with a certain scale, shape factor, and compression factor, and then using object-oriented fuzzy operators including AND, OR, MGE, MAR, MGWE and ALP, the classification process was performed. The object-Based fuzzy classification was also performed and the accuracy of each of the maps produced by the Object-Based method was also calculated. Producing a map of built-up urban lands with better accuracy using satellite images justifies the innovative aspect of this research. In this research, the AND fuzzy operator had the highest amount of accuracy in the produced maps, which indicates that by using Object-Based processing of satellite images, more accuracy can be achieved in the production of urban built-up lands.

The purpose of this article is to analyze and identify the factors affecting the sense of place in religious-cultural buildings and to promote these factors in order to enrich the sense of place in these buildings. The research method is descriptive-analytical. The statistical population is determined based on Morgan table = 78n = n. What distinguishes this research from its similar researches is the analysis and study of the components of sense of place in Ali Ibn Mahziar's tomb as the most significant shrine building in Ahvaz, which has not been researched in this field so far. The results of Pearson test, while confirming the correlation of all criteria and sub-criteria with the sense of place, show; The variable of peace and spirituality has the highest and the variable of security has the lowest correlation with the amount of sense of place. According to the results of regression test, perceptual and physical dimensions have the most effect and functional and social dimensions have less effect on inducing a sense of place in the shrine. The results show that in addition to the four components of physical, semantic, social and service, other components are involved in creating a sense of place in tombs and religious buildings.Therefore, it is possible to deepen the sense of place among pilgrims in pilgrimage buildings and religious tombs by providing more grounds for both physical and semantic components.
