Abstract: The appearance of city and urbanism is one of the important processes which have affected social communities .Being industrialized urbanism developed along with each other in the history.In addition, they have had simple relationship for more than six thousand years, that is , from the appearance of the first cities . In 18th century by coming out of industrial capitalism, progressive development took place in urbanism in the world. In Iran, the city of each region made its decision by itself and the capital of region (downtown) was the only central part and also the regional city without any hierarchy, controlled its realm. However, this method of ruling during these three decays, because of changing in political, social and economical issues that have caused changes in rural and urban relationship. Moreover, it has changed the variety of performance of cites and systematic urban network in Iran. Today, urban system has very vast imbalanced apace and performance. In Isfahan, the trend

Abstract: Wind turbine blades are mostly made of fibre reinforced plastics. However, in particular for the part connected to the hub steel may be used for large turbines in the future. A 3-dimensional rolling process was developed for such wing profiles, which are rolled to shape and thickness in one step. This paper deals with a practical way to access the load carrying capacity of hot rolled steel parts and to give a simple material model for design purpose. Based on systematic finite element analyses, which are compared to a 3-point bending experiment, the parameters for a bilinear material model are derived. The material model shall be suitable to reproduce the overall behaviour of the steel component so that accurate analyses are possible for structural design.
