Power-quality event analysis using higher order cumulants and quadratic classifiers
(IEEE-Inst Electrical Electronics Engineers Inc, 2006)
In this paper, we present a novel power-quality (PQ) event detection and classification method using higher order cumulants as the feature parameter, and quadratic classifiers as the classification method. We have observed ...
Road Roughness Modelling by Using Spectral Factorization Methods
(IEEE, 2016)
In this paper, road roughness model for the right and the left tracks are constructed by utilizing two methods. In the first method, from time-domain measurements the empirical auto and cross-power spectral densities of ...
Induction Motor Identification from Acoustic Noise Spectrum by a Covariance Subspace Algorithm
(IEEE Computer Society, 2018)
In this paper, we study identification of induction motors by using a recently developed covariance-based subspace algorithm from sound measurements. The sound data are collected by an array of five-microphones placed ...
Decentralized robust flow controller design for networks with multiple bottlenecks
(Institute of Electrical and Electronics Engineers Inc., 2003)
Decentralized rate-based flow controller design in multi-bottleneck networks is considered. An H? problem is formulated to find decentralized controllers which are robust to time-varying uncertain multiple time-delays in ...
Endpoint detection of isolated words using center of gravity method [Agirlik merkezi yöntemini kullanarak yalitik kelimelerin uç noktalarinin belirlenmesi]
(2007)
In this study, center of gravity (COG) method is proposed to detect endpoints of isolated words. Common vector approach (CVA) is employed to evaluate the effect of the proposed method in the isolated word recognition. Since ...
Detection of Voltage Flicker and Voltage Harmonic Using Hilbert Huang Transform
(IEEE, 2014)
Hilbert Huang Transform, which was suggested by Huang and improved by Flandrin and his group, is a new signal processing method. The analysis of nonlinear and non stationary signals can use HHT. This paper deals with the ...
A Comparative Study of Three Different Mathematical Methods for Solving the Unit Commitment Problem
(Hindawi Publishing Corporation, 2009)
The unit commitment (UC) problem which is an important subject in power system engineering is solved by using Lagragian relaxation (LR), penalty function (PF), and augmented Lagrangian penalty function (ALPF) methods due ...
Determination of displacements on a cutting disc during sawing process
(Elsevier Science BV, 2016)
In this paper, the displacement signals of a saw disc during cutting of square shaped metallic profiles are examined. The most important aspects of the study for sustainable manufacturing are reducing maintenance costs by ...
Wind Speed Prediction with Mycielski Algorithm
(IEEE, 2009)
Wind speed prediction is an important issue in wind related engineering studies. However, the wind data has random behavior like other meteorological events. Therefore, it is difficult to apply conventional statistical ...
Power quality event detection using joint 2D-wavelet subspaces
(IEEE, 2003)
In this work, we present a novel 2D representation of power system waveforms for the automatic analysis of transients. The representation is composed of a matrix whose rows are formed by time segments of digital waveforms. ...
