This paper proposes a simultaneous tuning method for PID controllers and dead-zone compensators based on particle swarm optimization. By the proposed algorithm, PID gains and dead-zone parameters are tuned online to minimize the error between the control output and the reference input. However, since ultrasonic motors intrinsically have a varying dead-zone in the control input associated with a...
This paper presents an improved zone content classification method. Motivated by our novel background-analysis-based table identification research, we added two new features to the feature vector from one previously published method [7]. The new features are the total area of large horizontal and large vertical blank blocks and the number of text glyphs in the zone. A binary decision tree is us...
در این پژوهش سنگ چینه نگاری، زیست چینه نگاری ریز رخساره ها و همچنین محیط رسوبی سازند سروک در طاقدیس آغار (جنوب غرب فیروزآباد) مورد بررسی قرار گرفت. برش مورد مطالعه در ناحیه مذکور 208 متر ضخامت دارد. در ناحیه مورد مطالعه، مرز زیرین سازند سروک با سازند کژدمی به صورت هم شیب و تدریجی می باشد و مرز بالایی این سازند با سازند ایلام یا سروک بالایی، بصورت ناپیوستگی فرسایشی است. سنگ شناسی سازند سروک در ب...
Background & objective: The present study was conducted to examine the risk factors associated with hand activity and to determine their cumulative effect on the development of upper extremity musculoskeletal disorders. Methods: The present clinical trial was conducted on 24 men and 6 women employed at a tea factory in Fuman in northern Iran. The human body map was used to assess the preva...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
