today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
Development of an Intelligent Cavity Layout Design System for Injection Molding Dies (RESEARCH NOTE)
This paper presents the development of an Intelligent Cavity Layout Design System (ICLDS) for multiple cavity injection moulds. The system is intended to assist mould designers in cavity layout design at concept design stage. The complexities and principles of cavity layout design as well as various dependencies in injection mould design are introduced. The knowledge in cavity layout design is ...
urban design problems have become so complex that no single designer is able to consider all aspects of a design area simultaneously. lately the application of computerized and scientific methods have helped designers analyze complex problems. one of these new methods is space syntax. the purpose of this study is to first investigate the strengths and weaknesses of this method and then suggest ...
برای اینکه یک ارتباط تلفنی ساده بین مبدا و مقصد برقرار شود نیاز به تجهیزاتی از قبیل گوشی تلفن مشترک a ، کابل جهت ارتباط با مرکز سوئیچینگ ، گوشی تلفن مشترک b ، اگر هر دو مشترک a و b در یک ناحیه نباشند در اینصورت نیاز به تجهیزات transmission که در مخابرات به قسمت pcm مشهور است . حال در نظر بگیرید مشترک a بخواهد با مشترک b تماس بگیرد چه کسی مشترک b را خبر می کند یا وقتی مشترک b گوشی را برمی دارد چ...
High-frequency velocimeters used for flow measurements during laboratory experiments allow the user to select range several operation parameters set up instrument optimal velocity measurement. The discrepancies between collected with different configurations can be significant, depending on flume bed configuration and boundary conditions. aim of this paper is quantify differences in profiles me...
In human-impacted coastal ecosystems, living shorelines are becoming a common restoration technique. However, we lack comprehensive understanding of the ecological and physical benefits, how they could inform management needs. To address this, studied effectiveness at broad spatial scale within Washington State boundaries Salish Sea, USA, with restored site ages spanning 1–11 years. We surveyed...

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
there is widespread recognition today that we are living in a period of profound technological, social, economic and political change, and that this process of change is accelerating. yet, there is less certainty about the nature and meaning of these changes—whether they should be regulated or liberalized, supported or resisted— and the kind of world they are leading to. despite these uncertai...
