In today's communities achieving to effectiveness of urban advertising is one of troubles of advertisement industry. This research is trying to answer this question that using three-dimensional design in urban advertising has what place in urban field? This query has been conducted in the method of iconological analysis on chosen urban advertising works of last 15 years in the world with the goal of achieve to volume effect on effectiveness of public advertisement. Results show that reason of effectiveness of chosen urban advertising (billboard) of last 15 years in the world (2000-2015) is -due to public audience of commercial advertisement and services- using volume display in the amount of 86.7% which among this number 83.3% of them have interacted with around environment space.

Recreation (creativity) is undoubtedly one of the important designing bases and a durable, matchless and unique factor which determines distinction, excellence, and elegance of a building in comparison with other buildings; and architecture as one of the manifestations of human life in a special time and place can be a reflection of thoughts, ideas and living method and also represent identity in shape of thought and creativity which is known as creator of architecture work from viewpoint of architecture. Firstly reflection of architect’s character in architecture work, then cultural concept of the work and its belonging to a specific social and ideological movement and besides talent and creativity of the artist, the cultural and artistic movements affect drastically on the result of architect’s act who is creator of the art work in form of an architecture event. Therefore it can be mentioned that variables of the present research are nominal and qualitative; the dependent variables are also of the same type. The effects of economic, political, social and cultural movements can also be mentioned which are expressed in form of concepts such as tangible and intangible strategies. The present paper attempted to analyze metaphors used in the major building of Behsharh Industrial Group, which is an objective evidence of Nader Ardalan’s work. The analysis was done in a historical-interpretation method and in qualitative form.

No unique method has been so far specified for determining the number of neurons in hidden layers of Multi-Layer Perceptron (MLP) neural networks used for prediction. The present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. The data used in the present research for prediction are consumption data of water subscribers in Fasa City of Fars Province (Iran) between the years 2010 to 2013. Ultimately, using the respective data set, the data of the subsequent year 2014 can be predicted. In the present research it was observed that the mean square errors of per data (MSEPD) for the abovementioned algorithms are less than 0.2, indicating a high performance in the neural networks’ prediction. Correlation coefficients using genetic and hill climbing algorithms were respectively equal to 0.891 and 0.759. Thus, GA was able to leave a better effect on optimization of neural network.

Urban spaces and in other words urban design and architecture have been found with close linkage with art and beauty especially the arts such as painting and sculpture. Addressing beauty at different areas such as creation of galleries to offer works of art, addressing form of urban spaces and representing works of art in urban environment have improved social life and increased identity, consensus and collective solidarity. On the other hand, it can provide an interesting and calm environment for the citizens and residents. Concurrent with the socio-political developments in the twentieth century and the progress of science and technology, all the areas of the arts were subjected to change. The metamorphosis of the art and stylistic developments took place and a large number of artists tended to innovative phenomena. Since the art at the twentieth century especially the second half of the twentieth century sought to affect the addressee, a group of the contemporary artists including sculptors have not known the tight enclosure of museums and galleries to represent their works and preferred to display their works at open space and wide and large places of cities. Representing works at open space requires largeness of dimensions of works at multiple scale and use of modern materials and techniques. Sol Lewitt (1928 - 2007) has been regarded among the artists at contemporary age at the area of Minimalism and Conceptual Art. American philosopher and theorist and contemporary art critic, Arthur Coleman Danto, has conducted articles in criticism to works by Sol Lewitt and has appeared in exhibition of his works. Lewitt made the earliest structures in 1965 and continued his activity at the 1970s by expansion of plans and planning for the larger projects which have been being made based on morphological and conceptual ideas. Ultimately his arrangements were proposed at huge scale and extended from the space of galleries and museums which tended to conceptual and minimalist art to the urban space. In the present research, works of this artist and ideas of Arthur C. Danto about minimalism and works of Sol Lewitt are analyzed. The main questions are as follow: What outcome representation of these works has in natural environment and urban space? how the border between art has removed the daily life and addressee?
