abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
This research investigated the effectiveness of IPM/FFS project from economic, technical, social-communicative, environmental and psychological aspects in a descriptive-correlational design based on the survey method. The research population consisted of 70 greenhouse producers that had implemented IPM/FFS project in Tehran and Alborz provinces, Iran. Using Krejcie and Morgan (1970)'s sample si...
Background and aims: during last decades, attention to ergonomic factors has been increased. Nowadays, most ergonomic assessors in workstations, assess ergonomic factors, considering either technical requirements or workers needs, both of which can affect design efficiency. But it seems an integration model of these two factors can be more effective. So this paper aims to present a pattern to a...
The course entitled ‘Product Design for Sustainability’ was opened in the Department of Industrial Design at the Middle East Technical University for graduate level students in the spring semester of 2011. Throughout the course, the nature of sustainability is examined so as to allow students to develop an understanding of its applicability to the area of product design and development. A usefu...
exogeneity and controllabillty of money is a basic assumption in neo-keynesian and monetarist analysis, as well as most contemprory economic macro-models. equilibrium path cattani & cavallo & khan model (j990)1 is employed, and pree & stienhe,2 model (j989) has been used for calculation of the real exchange rate unstability index. the results, indicate negative effects of real exchange rate dev...
When we consider large/expensive technical products/systems, it isoften the case (after some time) that repair is required toreplace modules that are not working and no longer commercially available orthe functionality ofthe system needs improving. The problem is to make these changes at minimal cost. In this paper, we outline a reconfiguration approach within our constraint-based model for the...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
