در محیط های دانشگاهی ایران ، آموزش ترجمه واژگان هم آیند که به منزله امری لاینفک برای دانش جویان رشته مترجمی زبان می باشد، تا حدود زیادی نادیده گرفته شده است . این واقعیت باعث شده است تا دانش جویان رشته مترجمی زبان در ترجمه ی واژگان هم آیند اشتباهات بسیاری مرتکب شوند. این پژوهش توجه ویژه ای به ترجمه واژگان هم آیند داشته است. برای مشخص نمودن مشکلات و استراتژی های مورد استفاده ی دانش جویان در ترجم...
Health is regarded as one of the basic rights of each person in society; so governments are obligated to provide it equally for everyone. The best way to achieve this goal is the establishment of health insurance with the orientation of family physician and the strategic referral system. Yet, such programs will not be successful without encouraging people to participate and changing social beha...
We consider minimal time problems governed by nonlinear systems under general time dependent state constraints and in the twoplayer games setting. In general, it is known that the characterization of the minimal time function, as well as the study of its regularity properties, is a difficult task in particular when no controllability assumption is made. In addition to these difficulties, we are...
Today, with an increasingly global population, agricultural production systems should meet the growing needs of food by using the new technologies. Increases in the level of production have inevitably resulted in some environmental issues. Addressing these problems require the application of organic farming as a sustainable way of agriculture system which possesses many promised advantages. How...

Abstract We consider the direct and inverse scattering problems for partially coated obstacles. To this end, we first use the method of integral equations of the first kind together with variational methods to solve a scattering problem for the Helmholtz equation where the scattered field satisfies mixed Dirichletimpedance boundary conditions on the Lipschitz boundary of the scatterer D. We the...
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
