با توجه به کاربرد وسیع فیلترهای آنالوگ زمان- پیوسته همچون طبقات مختلف مدارهای مخابراتی و مبدل داده، هر روز بر اهمیت طراحی فیلترهایی مناسب برای استفاده در مدارهای مجتمع افزوده می شود. همچنین با گسترش رو به رشد وسایل الکترونیکی قابل حمل در سال های اخیر، پردازش سیگنال حالت جریان به دلیل قابلیت طراحی مدارهای ولتاژ پایین، کم توان و دارای پهنای باند زیاد کارایی بسیاری یافته است. در این پایان نامه، رو...
this study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of iran at safiabad agricultural research center in 2014-2015. the cultivars included: 'gratex', '10j', 'wichita 6j', 'graking', 'choctaw' as pollinated cultivars (♀) and 'gratex', 'peruque', 'comanche 4m', &apos...
conclusions this study showed that, compared to simply increasing the dose of morphine, adding chloropromazine, promethazine, midazolam, and clinidine to morphine significantly controlled pain scores and increased treatment satisfaction in addicted patients without notable side effects. objectives the objective of this study was to evaluate the analgesic effects of adding clonidine, promethazin...
background & aim: the aim of this clinical trial study was to evaluate sleep quality in patients with chronic lung disease and the role of controlled breathing to improve the quality of sleep. methods & materials: sixty-four patients with chronic lung disease in two group (experimental and control group) enrolled in a 7 weeks. before interventions, the pittsburgh sleep quality index (psqi) and ...
conclusions the evidence that btx-a decreases ntg-induced cgrp-li and sp-li levels in trigeminovascular system suggests that btx-a attenuates migraine by suppression of neuropeptide release. btx-a injections for migraine at acupoint-sites and fixed-sites are effective. acupoint-sites btx-a administration shows more efficacy for migraine than fixed-sites application. results local btx-a injectio...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Rivers have a complicated and various condition in the diverse environment, and various science such as Hydrology, geomorphology, hydraulic, ecology and engineering have it been discussed. River geomorphology with studying of river process and landforms, examination of river landscape evolution, can be playing an important role in identifying of river channel character and behavior. To order th...
In this article we found the solution of fuzzy linear controlled systemwith fuzzy initial conditions by using -cuts and presentation of numbersin a more compact form by moving to the eld of complex numbers. Next, afuzzy optimal control problem for a fuzzy system is considered to optimize theexpected value of a fuzzy objective function. Based on Pontryagin MaximumPrinciple, a constructive equati...
زمینۀ مطالعه: توراکوسکوپی روشی کمتهاجم با کاربردهای تشخیصی، درمانی و تحقیقاتی در گونههای مختلف است، اما مطالعاتی که به استفاده از این روش در گونههای کوچکتر حیوانات پرداخته باشند کمتر به چشم میخورند. این مسئله میتواند به دلیل چالشها و سختیهای انجام موفقیتآمیز این روش در گونههای کوچک باشد. هدف: این مطالعه به منظور بررسی عملی بودن و معرفی بهترین رهیافت برای انجام توراکوسکوپی در خرگوش با ...
