  Background and Objective: Tissues that have been formed in the past and throughout a long process have been gradually weakened with the growth urbanization and urban development. On the other hand, the impacts of the immense growth of urban populations have led to a dispersed growth and the emergence of the marginalization phenomenon, having resulted in its own distinct problems. Yet, it is well-agree that the urban areas are the best option for urban development due to their existing infrastructure and urban amenities. Accordingly, the present paper seeks to locate these lands in the eroded urban fabrics of the Avini neighborhood by compiling the criteria and indices from theoretical texts and practical experiences to identify the lands susceptible to internal development.Method: In this regard, in order to reach a conceptual understanding and expert knowledge concerning the features of the lands susceptible to internal development, a questionnaire based on the theoretical framework was developed and completed by the urban planning experts on the one hand, the research method in this paper is, an F'ANP analytical method which is a combination of the functional analytical methods and the ANP; on the other hand, it is a secondary analysis of the location of the land susceptible to the development of an endogenous GIS.Findings: The findings of this study acknowledged that among all the factors affecting the identification of the lands susceptible to internal development in the Shahid Avini neighborhood, the performance criteria, and the accessibility and the related indicators attained the highest priority and prominence in locating these lands. Furthermore, a number of the parts related to the brownfields and the workshop located in the north and northeast areas of the neighborhood had a higher priority compared to the other parts to carry out the process of endogenous development with a weight between six and nine.Discussion and Conclusion: In line with the results of this study, among all the factors affecting the identification of the lands susceptible to internal development in Shahid Avini neighborhood, performance criteria and access and related indicators have the highest priority and importance in locating these lands. In addition, parts with barren use and production-workshop located in the northern and northeastern parts of the neighborhood, with a spatial weight between six to nine, have a higher priority than other parts to perform the process of internal development.  Manuscript profile

  In this paper, lift and drag forces of permanent-magnet electrodynamic suspension (PMEDS) System have been studied by considering the skin effect. Electrodynamic suspension is based on repulsive force between two magnetic fields with the same polarity. In this research the electrodynamic suspension system consists of a moving permanent magnet block levitated over a flat conducting plate with 2 mm thickness. At first, the analytical model of the PMEDS is proposed. For this propose, permanent magnet poles are modeled by the current sheets. Then the eddy current is calculated on aluminum sheet by considering the skin effect. Finally, the lift and drag forces are calculated in difference speed. The 2D finite element method is utilized to investigate the effect of speed variations on the performance of PMEDS at two different airgap. Two-dimensional finite element model, the accuracy of proposed analytical model is validated. The results of the finite element method are compared with results obtained by analytical model. It shows the accuracy of the analytical model in the estimation of the lift and drag forces of an electrodynamic suspension system. Manuscript profile
