چکیده
Abstract The increase of pore water pressure under a dynamic load is an important reason for the vibration liquefaction saturated sand. Therefore, studying model tailings sand plays role in seismic analysis ponds. In this paper, development characteristics fine and silt pond with centerline method are studied by triaxial tests. research results show that ratio shows trend "rising–smooth–rising" increasing frequency ratio, pore-pressure approximate linear stable trend. According to law pressure, new stress proposed fitting effect compared four different models, which verifies applicability predict growth silt.

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
