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 ...
The Defect Detection in Ceramic Materials Based on Time-Frequency Analysis by Using the Method of Impulse Noise
(Polish Acad Sciences Inst Fundamental Technological Research, 2011)
In this study, it was achieved by using the method of impulse noise to detect internal or surface cracks that can occur in the production of ceramic plates. Ceramic materials are often used in the industry, especially as ...
The determination of short circuits and grounding faults in electric power systems using time-frequency analysis
(Univ Cape Town, Energy Res Centre, 2015)
In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known ...
Application of Artificial Neural Networks for Defect Detection in Ceramic Materials
(Polska Akad Nauk, Polish Acad Sciences, Inst Fundamental Tech Res Pas, 2012)
In this study, an artificial neural network application was performed to tell if 18 plates of the same material in different shapes and sizes were cracked or not. The cracks in the cracked plates were of different depth ...
Application of artificial neural networks for short term wind speed forecasting in Mardin, Turkey
(Univ Cape Town, Energy Res Centre, 2012)
Artificial neural network models were used for short term wind speed forecasting in the Mardin area, located in the Southeast Anatolia region of Turkey. Using data that was obtained from the State Meteorological Service ...
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 ...
Effects Of Weather Conditions On Electromagnetic Field Parameters
(Ieee, 2015)
This study presents the results of electromagnetic field parameters measurements in an open area under different air temperature and humidity conditions. An attempt to consider the electromagnetic wave as a holistic harmonic ...
A Study on the Electromagnetic Fields in Wind Mills Farm Area
(Ieee, 2014)
This study presents the mathematical model of electromagnetic waveforms parameters which can be used for determination of the electromagnetic pollution level in windmills farm. The electromagnetic field parameters such as ...
Wind Speed Correlation Between Neighboring Measuring Stations
(Springer Heidelberg, 2012)
This study provides a wind speed estimation of the target station using wind speed data of the neighboring station despite the mountainous structure of the Southeastern Anatolian Region of Turkey. Within the study, a method ...
