Technology advances have made gigabit signal a viable and attractive. A method to design IEEE 1394 based 1GHz Phase Locked Loop (PLL) system as frequency synthesizer with Low Phase Noise is proposed. A complementary LC oscillator is used to generate the 1GHz oscillation frequency and is divided into lower frequency clock by the feedback frequency divider. The architecture is type II third order...

In this paper, a model for MEMS capacitive microphone is presented for integrated circuits.  The microphone has a diaphragm thickness of 1 μm, 0.5 × 0.5 mm2 dimension, and an air gap of 1.0 μm. Using the analytical and simulation results, the important features of MEMS capacitive microphone such as pull-in voltage and sensitivity are obtained 3.8v and 6.916 mV/Pa, respectively while there is no...

The article deals with algorithms for signal and image processing in presence of interference from the underlying surface, flicker noise, and other types of interference with fractal properties. Models of fractal interference are considered on the basis of the statistical approach. Application of the fractal Brownian motion model with fractional dimension is proved for the statistical descripti...

Electric arc furnace (EAF) is one of the most disturbing loads in power system as it highly time-varying and nonlinear. In this paper, new models based on instantaneous EAF voltage current, recorded from EAFs Mobarakeh steel company Isfahan/Iran are proposed. The focus paper developing efficient Schwarz model where three modified types original has four constant parameters. Unlike which uses in...

in order to identify the effects of vitamin a and aspirin on reducing uv lightinduced retinopathy, erg waves were compared before and after uv light exposure in rabbits. 30 rabbits were divided into 3 groups: the first group received vitamin a, 50,000 units i.m., single dose, the second group received aspirin, 50 mg/ kg/day po and the third group did not receive any medication. all three groups...

This study describes an approach to identify multiple flicker sources at the point of common coupling (PCC). The voltage signals different flicker such as electrical arc furnace, fixed-speed wind turbine, and diesel-engine driven generator were recorded PCC. For this purpose, various aerodynamic mechanical faults a turbine shear tower shadow, gearbox tooth-breaking, blade crash, pitch angle erro...

The problem of information extraction from discrete stochastic time series, produced with some finite sampling frequency, using flicker-noise spectroscopy, a general framework for information extraction based on the analysis of the correlation links between signal irregularities and formulated for continuous signals, is discussed. It is shown that the mathematical notions of Dirac δ and Heavisi...

In order to identify the effects of vitamin A and aspirin on reducing UV lightinduced retinopathy, ERG waves were compared before and after UV light exposure in rabbits. 30 rabbits were divided into 3 groups: the first group received vitamin A, 50,000 units I.M., single dose, the second group received aspirin, 50 mg/ kg/day PO and the third group did not receive any medication. All three gr...

Abstract: This paper presents a dual neural network based technique for detecting and classifying the power quality disturbances. In the proposed method, Adaptive Linear Neural Network is used to extract the rms voltage for harmonics and Interharmonics estimations. With the help of these indices, PQ disturbances such as Sag, Swell, Outages are detected and classified, Harmonics and Interharmoni...
