In this paper we describe how the Stepwise Adaptation of Weights (saw) technique can be applied in genetic programming. The saw-ing mechanism has been originally developed for and successfully used in eas for constraint satisfaction problems. Here we identify the very basic underlying ideas behind saw-ing and point out how it can be used for different types of problems. In particular, saw-ing i...
Abstract: The See-Saw mechanism provides a nice way to explain why neutrino masses are so much lighter than their charged lepton partners. It also provides a nice way to explain baryon asymmetry in our universe via the leptogenesis mechanism. In this talk we review leptogenesis and LHC physics in a See-Saw model proposed in 1989, now termed the Type III See-Saw model. In this model, SU(2)L trip...
Due to further applications of Surface acoustic wave (SAW) devices in many applicable electronics and communications fields, modeling and simulation for these devices become more urgent in recent years. SAW devices can found in frequency range from 10 MHz to several GHz. It can found in RF, IF, stages of mobile. SAW devices convert mechanical waves to electrical and vice versa through IDT. This...
توسعه ی شهری در هر کشور یک امر اتفاقی نیست و از سوی دیگر کنترل روند آینده ی آن، نیاز به برنامه ریزی های دقیق دارد.در این میان می توان به آسیب پذیری مخاطرات طبیعی در پهنه های شهری اشاره کرد، که در صورت عدم توجه به آن درصورتی که توسعه شهر به سمت اراضی با آسیب پذیری بالا باشد، میزان مخاطرات را افزایش داده و تلفات جانی و مالی فراوانی به همراه خواهد داشت. توجه به این امر محور اصلی این پژوهش می باشد....
This study aimed to the first report of Saw-belly, Hemiculter leucisculus from the Zarinehrud River and investigation of its morphometric and meristic characteristics, length-weight and length-length relationships. A total of 77 saw-belly specimens were caught on September 2013 from the Zarinehrud River. Twenty-one morphometric and 10 meristic characters were examined. The total length and weig...
A new micro gyroscope based on the surface acoustic wave (SAW) gyroscopic effect was developed. The SAW gyroscopic effect is investigated by applying the surface effective permittivity method in the regime of small ratios of the rotation velocity and the frequency of the SAW. The theoretical analysis indicates that the larger velocity shift was observed from the rotated X-112°Y LiTaO3 substrate...
Saw marks on bone have been routinely reported in dismemberment cases. When saw blade teeth contact bone and the bone is not completely sawed into two parts, bone fragments are removed forming a channel or kerf. Therefore, kerf width can approximate the thickness of the saw blade. The purpose of this study is to evaluate 100 saw kerf widths in bone produced by ten saw types to determine if a sa...
OBJECTIVES To evaluate the ability of an alignment jig/saw guide to reproduce appropriate osteotomy positions in the tibial plateau leveling osteotomy (TPLO) in the dog. METHODS Lateral radiographs of 65 clinical TPLO procedures using an alignment jig and freehand osteotomy performed by experienced TPLO surgeons using a 24 mm radial saw blade between Dec 2005-Dec 2007 and Nov 2013-Nov 2015 we...
صنعت بیمه از جمله پدیده هایی است که در تجارت داخلی و خارجی اعتبار و اهمیت خاصی دارد و رتبه بندی شرکت های بیمه علاوه بر آگاهی دادن به ذی نفعان، باعث افزایش رقابت، پویایی صنعت و توسعه ی جامعه می گردد. این پژوهش با استفاده از مدل کارت امتیازی متوازن (برای دست یابی به شاخص ها) و روش های madm شرکت های بیمه را رتبه بندی و ارزیابی می نماید. یکی ازموارد قابل توجه در استفاده از روش های madm، مستقل بودن ...
