  The establishment of each urban element in the specific location of the city follows special principles that if these principles to be considered well, will lead to the success and functional efficiency of that element in that specific location. In this context, the selection of a suitable location for the establishment of science and technology cluster as one of the urban distinctive elements has significant importance since those contain scientific, industrial, manufacturing, laboratory, research facilities, infrastructure and communication environments, institutions, individuals, and information based on creativity and innovation. Therefore, the present study was conducted aimed to find the most suitable location for the establishment of Yazd science and technology cluster. For this purpose after the study of global experiences and regulations and upstream documentation the requirements and necessities Clusters Site Selection were identified. Then, the effective parameters in two levels of main indicators and sub-indicators according to the Analytical Hierarchy Process Model were classified. Then, receiving information according to the experts, managers and professionals ideas analyzed by the Super Decision software and weight of the indicators was determined. In the next step, the satellite image of study area was prepared and using GIS, attempted for preparation of data layers based on requirements that come from the results of questionnaire and interviews. To achieve the final map that is obtained by overlaying weighted maps, first the importance of data layers in terms of distance has been determined and then using layers overlap method, Suitable location for the establishment of Yazd Science and Technology cluster has been proposed.

  In the recent years, importance and the role of small and medium enterprises was on the increase in industrial and developing countries. With the appearance of modern technology in the production and communications, some transitions have been created in the ways of production, distribution and organizational structure of agencies, and in this regard the importance of small and medium units has been found an upward movement. Developed countries and recently developed ones, have always applied special policies and strategies for improvement of small and medium industries and facilitating of enterprises entrance in the economical arena. They have applied those strategies for the competitions guarantee in the free market and restraint of big companies monopolization. Networking is referred to groups of enterprises which have cooperation in the special project with each other, and are using their own specialties for overcoming the usual and common difficulties, and gaining access to better efficiency. Networks are propounded in the universal trading subjects as a strong situation and condition, and have considered in the modern trading realm since 90s. Its importance as assistance in the creation of innovations in small and medium enterprises has been considered increasingly. Because small and medium enterprises have similar bonds, difficulties and opportunities, so they are providing the same networking policy strategy, the suitable networking facilities that are proportional with necessities and requirements of small and medium enterprises. Furthermore, clustering and networking of small and medium enterprises are considered as an important informational source and ideas creation for the process and productions innovations. On the other hand, the related small and medium enterprises can have the continual research and development, in which total sum of expenses is less than the research and developments expenses of each one solitarily and separately. In addition, products development, processs recovery, common consultation and coordination in the processs recovery of small and medium enterprises, which have been located in the networking discipline, are more fruitful than the processing and consultation of the distinct small and medium enterprises.Adoption of standard certificates and their related codes for the networking organizations is more accessible and cheaper. Also the instructional networks are providing this possibility, for accessing to the continual educational sources, for all small and medium enterprises in the networks. And finally advantages which obtained from the formation of small and medium enterprises networks can fulfill their needs in relation to their entrance to the universal competition arena. In this essay it was tried to consider the role of research and development networking among the small and medium enterprises and study the opportunities and problems which obtained from that. Furthermore, we will discuss the advantages and benefits of clustering and networking among the small and medium enterprises. The creation of values which obtained from research and development networking in the success and development of small and medium enterprises in the competition market will be analyzed too.

  According to definition, knowledge based economic development is creating value in society by means of wisdom, knowledge and technology. Some infrastructures for commercializing research outcomes and facilitating technological exchanges are required in order to form a system for getting to this point In other hand, Technology Clusters are geographic concentrations of interconnected knowledge-based and innovative companies who work closely with each other, local suppliers, infrastructure providers, educational institutions, and other relevant agencies. Cluster-based development is based on the premise that a company (and their region) can realize higher levels of competitiveness when it looks beyond its own limited capacity and strategically partners with other companies and support institutions to address challenges and solve problems that it is unable to solve when operating as an isolated entity. It is an approach that encourages companies who compete to come together and identify ways in which they can cooperate to their mutual benefit This paper, with a review to basic concepts, presents the main components and requirements of technology clusters along with a compatible model to use it more effectively for commercialization of technology and R&D outcomes in Iran.

  In a Competitive Market, Understanding Customer Demand and Effective Advertising is one of the most Important Factors in Survival. Extend the Internet and virtual networks have provided a great opportunity for companies to advertise, and thus studying electronic marketing methods and models is of great importance. One of the newest marketing methods is viral marketing that is based on mouth-to-mouth advertising and has a lot of power. Viral marketing relies on the principle that on any social network, a number of users have high power and influence on others, and by identifying them and creating good advertising messages, They can be used to effectively marketing. Therefore, The identification of important users is considered the most important activity in viral marketing. In this regard, various studies have been conducted to identify users using a variety of graph-based and publish-based methods. In this research, the capabilities of both methods have been used and by Using a semi-localized centrality criterion based on graph-based methods and Markov clustering model based on propagation methods, a new hybrid model for user clustering and identification of key users presented. The results show higher correlation between the proposed method and the SIR standard and, therefore, its higher efficiency than other methods used in the research. Manuscript profile
