Self-Organizing Feature Maps (SOFM) are a variety of artificial neural networks that their applications in the areas of pattern recognition and data clustering makes them noticeable tools to perform regional flood frequency analysis (RFFA). In this study, ability of Self-Organizing Feature Maps for regionalization of Sefidrood watershed in order to perform regional flood frequency analysis usin...
In today's age where knowledge is a driving force at regional and country level, the role of entrepreneurial ecosystems that foster the innovative and knowledge based entrepreneurial activities is very crucial in terms of competitiveness of resource attraction and wealth creation. Now the question arises: what is the model of regional competitiveness based on the knowledge entrepreneurship ecos...
In this paper, the problem of designing fixed-order robustH∞ controllers is considered for linear systems affected by polytopic uncertainty. A polynomial method is employed to design a fixed-order controller that guarantees that all the closed-loop poles reside within a given region of the complex plane. In order to utilise the freedom of the controller design, an H∞ performance specification i...
A reduced order output feedback controller is designed for a linear time invariant system, which guarantees that the closed loop poles are placed within some pre-specified stability region in the complex plane. A convex approximation of the non-convex constraints is used to pose a sequence of semi-definite programs, which provide the lowest order proper controller satisfying the approximate con...
The globalization and urban development concepts are closely linked to each other. However, all cities around the world are not affected same by globalization, each one has its spatial and reciprocal international-local action. The international changes of economy, culture, and politics have huge effects on restructuring of cities around the world. The present study as a descriptive-analytical ...
R egional unbalanced growth and the factors affecting it are one of the most important economic issues in developing countries. In this research, after evaluating the regional inequality at the provincial level of Iran, in order to examine the effect of economic factors on it, it was considered as a spatial econometric model using panel data during the period of 2001 to 2015. The evaluatio...
Since developments of the Arab world in 2011, Qatar has sought to introduce itself an important regional actor. Qatar's desire to engage in regional equations has contrasted with the policies of traditional actors such as Iran and Saudi Arabia. These paper tries to explain Qatar's foreign policy toward its regional rivals, Iran and Saudi Arabia, through statistical and mathematical data, by lin...
