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...

Cobalt ferrite or CoFe2O4 has unique physical and magnetic properties depend on its synthesis method. The application of cobalt ferrite as nanomedicine material become more interesting, however analysis on physical and magnetic properties based on synthesis method have not been discussed. The cobalt ferrite in this research was synthesised using two different methods: the ...

The main purpose of this study is providing a competency model for talent identification and succession in the National Gas Company. The research was conducted with a mixed approach. The statistical population in the quality department is the human resources managers of the gas company and 5 university professors and the sampling method is purposeful. In the quantitative phase, the statistical ...

Introduction: Dental maturation is a useful indicator of growth. Moreover, skeletal maturation is assessed by the cervical vertebrae maturation (CVM) stages, using lateral cephalometric radiographs. This study aimed to investigate the association between Demirjian’s method and CVM stages and also to analyze the diagnostic performance of the dental maturation stages for identification of ...

This paper deals with a discrete time repetitive control synthesis for non minimum phase plants. Two parts can be distinguished. The main design features of the repetitive controllers are discussed in the first part. More precisely one shows that one can realize two objectives; tracking with zero error and tracking with nonzero error. In the second part, a suitable plant model identification pr...

This paper describes a blind algorithm, which is compared with two another algorithms proposed in the literature, for estimating of the minimum phase channel parameters. In order to identify blindly the impulse response of these channels, we have used Higher Order Statistics (HOS) to build our algorithm. The simulation results in noisy environment, demonstrate that the proposed method could est...
