Continuous wavelet transform for ferroresonance phenomena in electric power systems
(Elsevier Sci Ltd, 2013)
The common characteristics of a nonlinear system are multiple equilibrium points, limit cycles, jump resonance and sub-harmonic generation. Ferroresonance is also a nonlinear electrical phenomenon, which occurs frequently ...
Spectral and statistical analysis for ferroresonance phenomenon in electric power systems
(Springer, 2012)
This study presents our findings on the ferroresonance phenomenon for the Seyitomer-Isiklar part of the Electric Power System of 380 kV in Turkey. In this context, the power spectral density approach and Short-Time Fourier ...
Defect Detection for Ceramic Materials by Continuous Wavelet Analysis
(Kaunas Univ Technology Press, 2011)
In this study, it is achieved to detect internal or surface cracks that can occur in the production of ceramic plates by using the method of impulse noise. Ceramic materials are often used in the industry especially as ...
Coherence analysis between hydrogen flow and electricity current in fuel cells
(Sila Science, 2012)
In this study the spectral properties of the hydrogen flow and electricity current data which are collected from a fuel cell system are extracted. The electricity current of the fuel cell system is in the DC character ...
Spectral and Statistical Analysis for Ceramic Plate Specimens Subjected to Impact
(Trans Tech Publications Ltd, 2013)
In this study, ceramic plate behaviour was elaborated on the basis at sound signal variations caused by the impact. All tests were performed using plate specimens and pendulum testing station; with date acquisition and ...
Detection of the Deformations in Ceramic Plates with Coherence Analysis and Transfer Function Model
(Kaunas Univ Technology Press, 2015)
In this study, in order to detect the deformation in ceramic plates, a new measurement method has been identified. In the measurement system, exerting impact on the ceramic plates that have the same features and size, sound ...
A neuro-detector based on the cybernetic concepts for fault detection in electric motors
(Jve Int Ltd, 2011)
In this study, an auto-associative neural network (AANN) is designed as a fault detector using the cybernetic concepts. In this sense, an artificial neural network structure is connected with a finite state system or a ...
Fault detection of washing machine with discrete wavelet methods
(Kaunas Univ Technol, 2014)
In the last decade, a new mathematical method has allowed scientists and engineers to view the details of time varying and transient phenomena that are not possible through conventional tools. This invention, called wavelet ...
Analysis of Vibration data at Properly Working Washing Machine with Time-Frequency Method
(Kaunas Univ Technology Press, 2013)
