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...
15 صفحه اولConstitutive Relation for an Orthotropic Body with Damage
In the present paper, the damage of fiber-reinforced composite laminates is considered with the aim to examine the change of their mechanical properties. The crucial issue for theoretical analysis is to construct constitutive relations, which take into account the development of damage, along with stress and strain. The paper is mainly focused on this problem. In order to derive an adequate des...
متن کاملطراحی، ساخت و کنترل model based یک روبات موازی هگزا
توسعه و افزایش تولید صنایع و در پی آن رشد اقتصادی و اجتماعی یک جامعه در قرن جدید، با خودکار کردن روندهای تولید گره خورده است. یکی از اجزای خودکار ساختن صنایع، استفاده از روباتها در چرخه تولید به منظورهای مختلف می¬باشد؛ رنگ پاشی، جابجایی، نصب قطعات و جوشکاری بخش کوچکی از فضایی است که به روباتهای کارا نیازمند است. پس از استفاده فراوان از روباتهای سرال در صنایع و انجام پژوهشهای پایه¬ای بر روی طراح...
Orthotropic remodelling of cancellous bone based on a parametric constitutive model - discussion of local microstructure constraints
Formation, maintenance and repair processes of bone tissues are only possible due to the internal ability of bones to remodel their microstructure. The mechanobiological factors of tissue formation, differentiation and regeneration in bone have been investigated by many authors. Here, the simplified yet well-justified Wolff's hypothesis will be recalled, postulating that processes of remodellin...
