Abstract In this paper, a flexible robotic arm system was designed and constructed based on the aspect ratio of arms. The mathematical modeling derived using finite element method. addition, necessary information about dynamic behavior suggested collected used to design controllers knowledge fuzzy logic theory. purpose building perform different movements while ensure accuracy model. This achie...

Quality control charts are limited to controlling one characteristic of a production process, and it needs large amount data determine limits the process. Another limitation traditional chart is that doesn’t deal with vague environment. The fuzzy work uncertainty exists in data. Also, investigate random variations found between samples. In modern industries, productivity often different designs...

Rosa damascena (Rosaceae) has been found to act on central nervous system including the brain. Several studies confirm that Rosa damascena inhibits the reactivity of the hypothalamus and pituitary systems in rat and can suppress the reactivity of central nervous system. In traditional medicine the hypnotic effect of rose is also suggested. In the present study hypnotic effect of ethanolic, aque...

The paper deals with both theoretical and application aspects concerning Iterative Feedback Tuning (IFT) algorithms in the design of a class of fuzzy control systems employing Mamdani-type PI-fuzzy controllers. The presentation is focused on twodegree-of-freedom fuzzy control system structures resulting in one design method. The stability analysis approach based on Popov’s hyperstability theory...

In today's highly competitive industrial environment due to fast technology development, quality practitioners will to detect out-of-control situations and take actions whenever is necessary as soon as possible. Accordingly, new statistical procedures have been enhanced incessantly both to handle high yield processes along with looking for methods of minimizing all quality cost. CCC-r chart, th...
