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 ...
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 ...
The application of instantaneous reactive power calculation methods to a real power system
(Sila Science, 2012)
Many calculation methods have been developed to calculate the reactive power used in energy transmission lines. In this study; preferred instantaneous power calculation techniques such as instantaneous orthogonal currents, ...
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 ...
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 ...
A proposal for visually handicapped students to use electrical control laboratory
(Jve Int Ltd, 2011)
In this paper a technical solution is presented for blind or visually impaired students to acquire abilities of experimental work in laboratory conditions enabling them to participate in the experiments jointly with the ...
Spectral and Statistical Analysis for Ceramic Plate Specimens Subjected to Impact
(Trans Tech Publications Ltd, 2013)
