data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
همگام با سرعت در حال رشد خلاقیت و نوآوری های آموزش زبان به ویژه ظهور روش ارتباطی آموزش زبان? بسیاری از مدارس زبان با بازاندیشی آموزش و پرورش خود? برای گنجاندن فعالیت های ارتباطی، وزمینه ی شخصی سازی شده به شیوه های سنتی خود به روز رسانی شده اند. با این حال، مدارس ایرانی در این زمینه آهسته پیش رفته اند. از این رو، هدف عمده ی پژوهش حاضر برداشتن یک گام در پر کردن شکاف بین نظریه های آموزشی نو ظهور و...
plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...
Colorless sodic and sodic-calcic amphiboles occur in piemontite-quartz schists in the Asemi-gawa (garnet zone) and Besshi (albite-biotite zone) areas of high P-low T Sanbagawa metamorphic belt in central Shikoku, Japan. Colorless sodic amphiboles in the Asemi-gawa area are glaucophane while colorless sodic-calcic amphiboles from the Besshi area are barroisite and magnesiokatophorite. Colorless ...
the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...
the chadegan metamorphic complex is a wnw-ese- trending antiformal structure located in sanandaj-sirjan structural zone, iran.the inner core of the structure is made of orthogneiss, containing eclogitic lenses. schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. two main deformational episodes have been documented in theschists an...
Synthetic Aperture Radar (SAR) is the only way to evaluate deformation of the Earth’s surface from space on the order of centimeters and millimeters due to its coherent nature and short wavelengths. Hence, by this means the long term risk monitoring and security are performed as precisely as possible. Traditional SAR imaging delivers a projection of the 3-D object to the two dimensional (2-D) a...
Super duplex stainless steel is a kind of duplex stainless steel that has pitting resistant equivalent number over than 40. Unified Numbering System (UNS) S32750 is a common super duplex stainless stee, that is mostly applied in oil and gas refinery industries, because of its proper corrosion-resistant properties . Therefore, joining of these steels by welding is very important, but the greates...
