آرایه های منطقی برنامه پذیر در حوزه کار (fpga) به یکی از عمومی ترین واسطه های پیاده سازی مدارات دیجیتال تبدیل شده اند. در طی پانزده سالی که از معرض آنها می گذرد، اکثر تحقیقات انجام شده بر روی fpga ها در راستای کاهش مساحت و افزایش سرعت کار آنها بوده است . زیرا fpga ها به خاطر اینکه انعطاف پذیر ترین افزاره های برنامه پذیر هستند، نسبت به دیگر واسطه های پیاده سازی کندتر و بزرگتر می باشند. معماری مو...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...
The angular error of indexing table on machine tool is measured using new developed measuring device. The measuring techniques, which have been reviewed in this paper, are currently available in manufacturing engineering to calibrate the angle measurement. The new developed measuring device using 6 points kinematic concept and employing ball and vee grooves is used to calibrate angle errors of ...
Introduction: Musculoskeletal disorders are one of the prevalent factors that lead to absenteeism at work. The purpose of this study was to evaluate the physical posture and methods to improve workstations in the petrochemical industry. Methods: This interventional study was carried out at the Petrochemical Company and according to the type of work and posture evaluation using two methods QEC a...
