ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
There are several parts of the video encoding process that can be optimized for high quality, high compression ratio and fast encoding speed. In this paper we focus on some of these encoder optimization issues. We first study motion estimation, a computationally intensive part of encoding, and propose efficient algorithms based on exploiting spatially correlated motion, that perform well in ter...
Motion measurement of video signal has been one of the most researched topic in the field of video processing [1], [2]. The need for true and accurate motion measurement is a necessity for video coding and motion compensated picture processing. Very few algorithms have been proposed that are both efficient in terms of accuracy, complexity and ease of implementation in reference hardware and sof...
PURPOSE To test the feasibility and accuracy of measuring joint motion with real-time MRI in a 1.5T scanner and in a 0.5T open-bore scanner and to assess the dependence of measurement accuracy on movement speed. MATERIALS AND METHODS We developed an MRI-compatible motion phantom to evaluate the accuracy of tracking bone positions with real-time MRI for varying movement speeds. The measurement...
the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...
