The research analyses the essence and relationships between the variables in the context of light and architecture, and it aims to develop the knowledge and design based on the light and recognition of the space, an effort was made to analyze the role of light on quality of the Iranian architecture and three samples of the most precious mosques were selected as the instances of this phenomenon,...

in this paper, we introduce the concepts of $2$-isometry, collinearity, $2$%-lipschitz mapping in $2$-fuzzy $2$-normed linear spaces. also, we give anew generalization of the mazur-ulam theorem when $x$ is a $2$-fuzzy $2$%-normed linear space or $im (x)$ is a fuzzy $2$-normed linear space, thatis, the mazur-ulam theorem holds, when the $2$-isometry mapped to a $2$%-fuzzy $2$-normed linear space...

the aim of this research paper was to determine the role of urban space design on cities competitiveness in the process of globalization. in the era of globalization and with the rush of investors to find attractive places for investment, cities are becoming the focal points for investors and the urban managers, who need to present a variety of attractions to draw financial capital and be able ...

in this paper, the operation of helix traveling wave tube in interaction region is investigated by using a three dimensional large signal lagrangian model in frequency domain. the complete simulation of these tubes is essential for optimum design and minimum manufacturing cost. this 3d code can compute interception current (or current losses ), beam radius changes in interaction region and the ...

nowadays, numerous realities in the field of architecture has gathered architects’ concentration; this has alienated designer’s attention from theoretical thinking in the initial stages of design process. new considerations such as human attitude and orientation in urban areas, the environmental impacts, behavioral relations between man and building, considering sociology and psychology in crea...
