The novel Malekan-e- Azab is the latest published work by Abu Torab-e Khosravi. The significance which is always assumed by Khosravi for words and writing is conspicuously seen in this novel as well; however, the author’s attempt to develop novel atmosphere and techniques has added a new dimension of complexity. To fully appreciate this complication and to gain an understanding of the dis...

the importance of drawing by hand in architectural design process is undoubtedly clear. nevertheless, different computer software for drawing and designing in the field of architecture are growing rapidly and the confrontation of these two different types of drawing has become an important subject of discussion, which needs to be addressed analytically. this article attempts to analyze the use ...

the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

Intelligent deep-drawing is an instrumental research field in sheet metal forming. A set of 28 different experimental data have been employed in this paper, investigating the roles of die radius, punch radius, friction coefficients and drawing ratios for axisymmetric workpieces deep drawing. This paper focuses an evolutionary neural network, specifically, error back propagation in collaboration...

In this paper, the problem of minimizing the number of drawing stages and heat treatments needed for the multi-stage deep drawing of cylindrical shells is addressed. A conventional rule-based computer-aided process planning (CAPP) is utilized within a dynamic programming approach to generate a set of alternative optimal process plans. A finite element analysis is carried out to guide the select...
