چکیده
The methodology in the seismic design of slopes has evolved with technological advancement and development geotechnical engineering, methods great limitations such as pseudostatic analysis to rigorous that require a lot information for better understanding behavior soil dynamic analysis. This article develops procedure, comparison application simplified earthquake-induced displacement methods, which are Newmark method (1965), Makdisi & Seed (1978), Bray Travasarou (2007), Bray, Macedo (2018). Each these displacements is associated model explains sliding mass, rigid block model, decoupled coupled analyzed this article.
 As an applicative case, earthen dam rocky central core 50 m high placed sandstone strata moraine deposits interspersed shale intrusions shown, consideration Lima 1974 earthquake, Attic 2001 earthquake were used. Pisco 2007, considering both NS EW directions. Likewise, response spectrum on fault surface, resulting from 3 columns dam, considered information. (2018) applied, obtaining deformation results between 1 10 cm according their order magnitude represent stable condition dam.

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
