in this paper, a novel method is developed for designing the output feedback controller for static synchronous series compensator (sssc). in the proposed method, the problem of selecting the output feedback gains for the sssc controllers is changed into an optimization problem with a time domain-based objective function.then, it is solved by using the particle swarm optimization (pso) algorithm...
computer-integrated manufacturing (cim), technologies are presented as solutions tomanufacturing organizations, which need to perform well in all customer-related dimensionssimultaneously. in the literature, cim technologies providing such benefits as more frequentproduction changes, reduced inventory level, improved ability of producing complex parts with ahigh degree of accuracy and repeatabi...
in recent years, encapsulation of drugs and antigens in hydrogels, specifically in calcium alginate particles, is an interesting and practical technique that was developed widespread. it is well known that alginate solution, under proper conditions, can form suitable nanoparticles as a promising carrier system, for vaccine delivery. the aim of this study was to synthesis alginate nanoparticles ...
the science parks have important role in development of technology and are able to make economic growth of the countries. the purpose of this paper is the presentation of a fuzzy expert system (fis) as intelligent systems to evaluate the science and technology parks. one of the problems for evaluating science and technology parks is to have the high number of criteria and science parks which ah...
this paper presents a novel indirect adaptive power system stabilizer (pss) via a developed synergetic control methodology and fuzzy systems. fuzzy system is utilized in an adaptive scheme to estimate the system using a nonlinear model. the synergetic control guarantees robustness of the controller and makes the controller easy to implement because of using a chatter free continuous control law...

this paper presents an efficient global meta-model building technique for solving high fidelity multidisciplinary design optimization (mdo) problems. the main difficulties associated with mdo are often characterized by interdisciplinary couplings, high computational cost of an analysis in individual disciplines and a large number of design variables and constraints. these issues result in very ...
سیستم های فراپهن باند با قابلیت انتقال داده با سرعت بالاتر و مصرف توان کمتر، توجه زیادی را به خود جلب نموده اند. تقویت کننده کم نویز یک بلوک حساس در گیرنده های فراپهن باند می باشد که باید مشخصات دقیق زیادی را نظیر امپدانس ورودی پهن باند، بهره کافی، عدد نویز پایین، مصرف توان کم و مساحت تراشه کوچک فراهم آورد. برای تقویت کننده کم نویز مسئله تأمین بهره کافی و ایجاد نویز کم اهمیت ویژه ای می یابد، چو...
برای رسیدن به سطوح بالای پوشش خطا، معمولا تغییرات زیادی در مقادیر سیگنالهای داخلی مدار ایجاد می گردد که باعث افزایش مصرف توان نسبت به حالت کار عادی مدار است. علاوه بر این آزمون مبتنی بر پویش در زمان شیفت دادن بردارها تعداد زیادی گذار در ورودی مدار تحت آزمون ایجاد می نماید که این مسئله باعث فعالیتهای کلیدزنی زیاد در مدارهای داخلی واحد تحت آزمون و افزایش توان خواهد شد. توان مصرفی بالا در زمان آزم...
