1. Introduction Resonators are the basic building blocks of rf filters and oscillators. Like any other circuit component, a resonator must be experimentally tested to determine its properties. The three fundamental characteristics of an rf resonator that have to be determined by measurement are: (1) resonant frequency, (2) coupling coefficient, and (3) unloaded Q factor.

in this study, analysis is presented in two steps. in the first step, the theoretical s-wave displacement spectra, conditioned by frequency-independent q, was fitted with the observed displacement spectra. therefore corner frequency, moment magnitude and frequency-independent q for each record were estimated simultaneously and the estimate of error is given in the root-mean-square sense over al...

the purpose of this research was to determine the attitude of agricultural advisory and technical engineers towards anreo. the population of this study included 127 engineers in songhor township. based on their job tenure and field of study, a purposeful sample of 45 engineers participated in this study. this study was conducted using q methodology. it is a combination of qualititative and quan...

feeding performance of the green oak leaf roller, tortrix viridana (linnaeus) was determined on three host plants including quercus libani oliv, quercus infectoria oliv, and quercus branti lindl, under laboratory conditions. mean total leaf weight consumed by larvae was the highest on q. branti (0.31 g) and the lowest on q. libani (0.14 g).the feeding index was the highest on q. libani while th...

The neutron charge form factor G En (q) is determined from an analysis of the deuteron quadrupole form factor F C2 (q) data. Recent calculations, based on a variety of different model interactions and currents, indicate that the contributions associated with the uncertain two-body operators of shorter range are relatively small for F C2 (q), even at large momentum transfer q. Hence, G En (q) ca...

The statistical analysis in Q-methodology is based on factor analysis followed by a factor rotation. Currently, the most common factor extraction methods are centroid and principal component extractions and the common techniques for factor rotation are manual rotation and varimax rotation. However, there are some other factor extraction methods such as principal axis factoring and factor rotati...
