DESIGN AND PARAMETERS OF WATER-PURIFYING RADIAL FILTERS

Design of polar-separable FIR filters by radial slice approximations

We introduce the design of polar-separable 2-D FIR lters by radial slice approximations (RSA). It is a two step procedure. First, 1-D lters for the radial and the angular components are designed. Then the desired lter response is approximated on many radial slices in a weighted mean square sense. In the case of circular lters, RSA outperforms other design procedures in terms of ripple size and ...

technical and legal parameters for determination of river boundary,( case study haraz river)

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...

Design Algorithms for Doppler MTI and Filters (Using Chebyshev Approximation)

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
