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...

growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...

Introduction: Simultaneously with the changes of techniques and skills, and the emergence of new phenomena in information communication technology, e- learning as a knowledge acquisition tool, rapidly is expanding, developing and evolving. On the other hand, due to environmental conditions and crises, the traditional education is encountered with serious threat, electronic (e)-learning is consi...

حلقه r، آیکدا ناکایاما حلقه (حلقه –in) نامیده می شود هرگاه پوچ ساز چپ اشتراک هر دو ایده آل راست برابر با مجموع پوچ سازهای چپ آن دو ایده ال باشد. در این پایان نامه نشان داده می شود که اگر r یک in-حلقه راست باشد و a,b دو ایدآل راست r باشند که مکمل یکدیگرند، آن گاه خود توان e?r وجود دارد به طوری که a=er و b=(1-e)r. به عنوان یک نتیجه نشان داده می شود که r خود تزریقی راست است اگر و تنها اگر m2(r) یک...
