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 اولSliding Friction Contact Stiffness Model of Involute Arc Cylindrical Gear Based on Fractal Theory
Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...

translation of collocations from english into persian, based on ghazalas theory
غزالا همایندها را به صورت ترکیبی از دو یا چند واژه که همواره در متون مختلف زبان ها همراه با هم می آیند تعریف می نماید. از دیدگاه او روند رو به رشد میل به ترجمه ی همایندها در مطالعات ترجمه، به دلیل اهمیت آنها در انسجام ساختار زبان است. این پایان نامه اساسا به ترجمه ی همایندها منحصر شده است. هدف آن بررسی کاربرد راهکارهای غزالا در مورد ترجمه ی همایندها از انگلیسی به فارسی است. هدف دیگر آن یافتن پر...
15 صفحه اولToward real-time detection of deep tissue injury risk in wheelchair users using Hertz contact theory.
This study assessed the suitability of a new portable system that is based on Hertz's contact theory for evaluating internal gluteal muscle stresses under the ischial tuberosities of wheelchair users in real-time as a risk indicator for a deep tissue injury. Sitting in a wheelchair was monitored and processed with the portable system for six control subjects and five individuals with paraplegia...
