The satisfying of human needs through designing technical objects requires the compromisation and settling of various conflicting criteria at different stages of the engineering design process. The need for back and forth adjustment of design specifications, concept finding, and design embodiment can be considered to be carried out in a telescopic review fashion. The present study is concerned ...

poly(vinylidene fluoride) (pvdf) nanofibers were prepared via electrospinning process. several different factors influence on this process and application of experimental design for its optimization is of great importance. the central composite design (ccd) was used for planning and optimizing of the experiments and also, the analysis of variance (anova) was employed for the statistical validat...

functions in landscape design include values in design and management process to satisfy moral and environmental needs that current attitudes see that as open space design by natural and man-made elements, while the basic intellectual layers related to human as the principles of environmental design have been forgotten. human urban knowledge seeks to meet in health, biological, psychological, s...

A procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. The method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. The main advantage of this systematic procedure with respect to other reported procedures is using non-equilibri...

the oil content of the wax produced in a dewaxing process is the key economic parameter thatshould be reduced as much as possible. some factors such as the type of solvents, cooling rate,temperature, and solvent to oil ratio influence the dewaxing process. due to the fact that crude oildiffers from place to place and since the operational conditions for wax extraction vary for differenttypes of...

design process consists of multiple coherent stages in which a lot of factors involve and their impact on each other is inseparable. design is a process of transfer, translates, and interact the concepts and internal ideas of designer through sketches. visual reasoning is the main factor in connecting designer's knowledge and experiences through sketch and continues till achieving a satisf...
