Analysis of Vibration data at Properly Working Washing Machine with Time-Frequency Method
(Kaunas Univ Technology Press, 2013)
In this study, the vibration analysis of the properly working washing machine and the washing machine having axial disturbance were made. The received data from analysed machine were processed for spectrum analyses through ...
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 ...
Reverse Power Data Analysis and Feature Extraction Based Upon Continuous Wavelet Transform for Electric Power Plants
(2010)
This study is focused on the investigating of a power plant generator in reverse power condition. For this purpose, reverse power data were collected from a Combined Heat and Power Plant generator protection relay. The ...
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 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 ...
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 ...
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 ...
System of Power Supply and Oscillating Pulse Current Synchronous Drive in Power Network
(Ieee, 2014)
There are a number of electrical drives with oscillatory driven mechanisms. As a result it is possible to use oscillating movement electrical drives there. These drives create ineligible reactive power, therefore it is ...
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 ...
The defect detection in ceramic materials based on wavelet analysis by using the method of impulse noise
(Jve Int Ltd, 2013)
In this experimental study, it was achieved to detect internal or surface cracks that can occur in the production of ceramic plates by using the method of impulse noise. This method is a test technique which was not used ...
