ENVIRONMENTAL ASSESSMENT OF WIND ENERGY CONVERSION SYSTEMS IN TURKEY
(Scibulcom Ltd, 2012)
Nowadays, approximation of fossil-based fuel to exhaustion reveals that countries will have difficulty in meeting energy needs in the near future. Renewable energy sources are prognosed as a solution to this problem. Among ...
Application of wavelet transform to defect detection of building's structure
(Kaunas Univ Technol, 2012)
Various methods can be used to detect the defects of structures. In this paper wavelet transform method is used. Continuous wavelet transform (CWT) is applied to vibration signal analysis of building's construction with ...
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 ...
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, ...
Testing the reliability of a velocity definition in a dispersive medium
(Amer Physical Soc, 2012)
We introduce a method to test if a given velocity definition corresponds to an actual physical flow in a dispersive medium. We utilize the equivalence of the pulse dynamics in the real-omega and real-k Fourier expansion ...
Speed Estimation of Brushless Direct Current (BLDC) Motor with Multilayer Perceptron
(Wydawnictwo Sigma-N O T Sp Z O O, 2012)
This study used an artificial neural network model to estimate the revolutions per minute of a brushless direct current (BLDC) motor operating at different driver modes and different load currents. The dataset that was ...
An investigation into the usability of straight light-pipes in Istanbul
(Sila Science, 2012)
With the impact of global warming, recent years has witnessed a tremendous revival of interest in environmental issues. At the moment, the world's electricity generation mainly depends on the fossil fuels which are eventually ...
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 ...
Diagnostics of construction defects in a building by using time-frequency analysis
(Kaunas Univ Technol, 2012)
The paper analyzes the problem of detection and identification of the defects in the layers of the buildings. In order to analyze the behaviour of the damaged and undamaged layer, the defects in the layers were modelled ...
Spectrum Analysis of GMA Welter in Various Working Modes
(Budapest Tech, 2012)
In this study, a current drawn by a welter at initial, stable-state and finish modes is examined using spectral analysis. The current shunt measurement method is utilized in order to measure the current drawn by the welter. ...
