friction-stir welding process is a novel method of solid state welding, which produces heat due to friction between the pin, the shoulder and the workpiece. this heat causes a paste area. shoulder pressure and pin spin cause edges integration and lead to welding. in this study, firstly, the feasibility of welding of steel sheet (en10130) with a thickness of 1.5mm has been tested by 58 experimen...

The main aim of this article is to analyze the applicability resulting from the practice, a new method of designing information systems operationally named confrontational pattern design method. At the beginning of the work the specificity and assumptions a new methodology is presented and its compatibility with modern design methods. This is followed by studies, which verify of the application...

this paper evaluates and ranks the temporal dimensions, known as fourth dimension of urban design, of a number of places in a city by topsis method. topsis method is technique for order preference by similarity to ideal solution. topsis is one of the renowned methods for classical multi-criteria decision-making (mcdm) problems that defines the positive ideal solution and negative ideal solution...
