It is argued that the flow process analysis essentially provides two new options for improvement of production: elimination or reduction of non value adding activities (also called waste) in flow processes and increase of output value from the customer point of view. The typical categories of waste and value loss in a construction project are analyzed in this framework, and the corresponding im...

In this study, two goals are followed. First, by means of the Generalized Differential Quadrature (GDQ) method, parametric analysis on the vibration characteristics of three-parameter Functionally Graded (FG) beams on variable elastic foundations is studied. These parameters include (a) three parameters of power-law distribution, (b) variable Winkler foundation modulus, (c) two-parameter elasti...

The dynamic behaviour of a circular plate in contact with fluid and resting on two-parameter elastic foundations is of interest in the field of geotechnics, structure, highway, railway, oil and gas and mechanical engineering. In this work, the dynamic behaviour of circular plate in contact with fluid and resting on Winkler and Pasternak foundations is investigated. The coupled differential equa...

in order to restrain the potential of wind energy, the first step is to determine the wind energy potential. in this study the wind data was used from the three-hour frequency recording of 10-year period (2002-2011). to predict the occurrence probability of each wind speed, the two-parameter weibull function was used. the goodness of fit test by chi-square test showed that the wind speed distri...

A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...

In this study a time-frequency method based on Wigner-Ville Distribution (WVD) is used for detection and parameter estimation of Frequency Modulated Continuous Wave (FM-CW) Radar Signal. The proposed method uses the Pseudo-Wigner-Ville Distribution (PWVD) as a time-frequency detection technique and Radon Transform to identify the parameter of the modulation. The Wigner-Ville Radon Transform (WV...

In this paper, a frequency-variation based method has been proposed for transistor parameter estimation in a commonemitter transistor amplifier circuit. We design an algorithm to estimate the transistor parameters, based on noisy measurements of the output voltage when the input voltage is a sine wave of variable frequency and constant amplitude. The common emitter amplifier circuit has been mo...

This paper presents the steps of the approach to identify the linear parameters of a salient-pole synchronous machine at standstill and by frequency response tests data (SSFR). It is currently established and demonstrated that stability parameters for synchronous machines can be obtained by performing frequency response tests with the machine at standstill. The objective of this study is to use...

This paper presents a novel approach to parameter estimation based on the sample covariance matrix linear processing. The originality of this framework relies upon two facts: firstly, the gaussian assumption about the nuisance parameters is avoided and, secondly, quadratic feed-forward schemes are designed saving the complexity and delay of conventional ML-based algorithms that carry out an exh...
