Surface acoustic wave (SAW) sensors are currently being investigated in a wide range in fields including physical, chemical and bio-sensing. The basic principle in a SAW sensor is the detection of changes in the propagation characteristics of the surface acoustic waves which are caused by perturbations on the active surface of the device. The most common situation is measuring the change in pro...

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...

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...

شاخص های مسکن از مهمترین موارد در برنامه ریزی ها و شناخت وضع موجود است که بررسی آن باعث می شود در اولویت های برنامه ریزی و ارائه پیشنهادات به نحوی مطلوب تاثیرگذار واقع شوند. کلانشهر تهران به عنوان پایتخت و پرجمعیت ترین شهر کشور دارای مشکلات متعددی در بخش مسکن می باشد که توجه به برنامه ریزی های متناسب با شرایط موجود در جهت بهبود وضعیت مسکن در آینده باید مد نظر قرار گیرد. در این پژوهش با استفاده ...

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...
