In this article, the sliding mode control of frequency load control of power systems is studied. The study areaconsists of a system of water and heat. First, a mathematical model of the proposed system disturbances ismade and then sliding control mode for frequency load control is provided. By the system simulation andsliding mode control, it can be shown that the damping of oscillations is wel...
conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardi...
In this paper, a novel approach for two-loop control of the DC-DC Ćuk converter in discontinuousconduction mode is presented using a sliding mode controller. The proposed controller can regulatethe output of the converter in a wide range of input voltage and load resistance. Controllerparameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of thedeveloped sl...
Brushless doubly fed machine (BDFM) is indeed an induction machine which has two windings in the stator and a cage rotor with a special design. Due to absence of brushes and slip rings, this machine is considered for the applications needs high reliability, such as wind turbines. In this paper, stead state performance of BDFM in synchronous mode of operation, the most interesting mode of operat...
اندازه گیری، اجرا و تحلیل راهکارهای کاهش زمان انتظار مراجعین به مراکز درمانی عمومی بر پایه شبیه سازی
زمینه: مدیریت یک مرکز بیماران سرپایی بسیار مشکل است.همیشه مهمترین مشکلی که مدیریت در این مراکز با آن مواجه است زمان انتظار طولانی بیماران است و بدتر اینکه زمان مشاوره و سرویس گیری بیمار بسیار کمتر از زمان انتظار است.سیستمهای مراقبت از سلامت کاملا پیچیده و دارای منابع محدود هستند. لازم است راهی بیابیم تا هم رضایت بیمار و هم بازده کلی سیستم افزایش یابد.جهت افزایش رضایت بیمار و بازده کلی سیستم بای...
introduction radon is a colorless and tasteless gas which exists in most soils. it is a substance that poses a potential risk for lung cancer in case a person is exposed to high levels over long periods of time. the environmental protection agency (epa) estimates that 90% of lung cancers per year are caused by radon. the aim of this paper is to estimate the absorbed doses of 222rn by mcnpx simu...
the paper will provide a summary of all lifelines performance in this strong earthquake. the paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. the impact as a result of the lifelines service interruption will be discussed; most important is the ...
small scale industries are suffering most from the marketing problems due to their owners’ attitudes, units’ capacity, and quality of products along with the scale of production. the researchers analyzed the problems of selected twenty small scale industrial units of various industrial groups of industrial estates of sylhet division of bangladesh to get insights of the problem. primary and seco...
مقدمه: هدف این مطالعه اندازه گیری دقیق پاسخ های قلب به تمرینات استقامتی با استفاده از دو روش m-mode و توزین در موش ها و هم چنین ارزیابی تغییرات ناشی از تمرین در قلب و بطن چپ به نسبت وزن بدن، طول استخوان درشت نی و سطح رویه بدن است. بحث و نتیجه گیری: به نظر می رسد، برای ارزیابی سازگاری های قلبی ناشی از فعالیت های استقامتی، روش m-mode قابل اعتماد تر است. به علاوه برای نسبی کردن شاخص های وزنی قلب، ...
breed-wise standard echocardiographic values in dogs have been reported as there is variation in body and chest conformation which limits the application of data of one breed for other breed. labrador retrievers being originated from hunting dogs, might have different echocardiographic values from standard normal range of other dog breeds. so, the present study was aimed to determine the m-mode...
