The effect of model generated solar radiation data usage in hybrid (wind-PV) sizing studies
(Pergamon-Elsevier Science LTD, 2009)
Wind speed and solar radiation characteristics belonging to past years of a region are the main input parameters in wind-photovoltaic hybrid system (WPHS) sizing studies. Classically, these data are fed to several scenarios ...
PLD: Power line detection system for aircrafts
(Institute of Electrical and Electronics Engineers Inc., 2017)
Power Line Detection (PLD) is still an important issue for aircraft safety. In this study, two simple PLD algorithms are developed that utilize two alternative line detection algorithms (EDLines and LSD) and feed their ...
A novel wind speed modeling approach using atmospheric pressure observations and hidden Markov models
(Elsevier Science BV, 2010)
Modeling the wind speed data has important implications in wind studies, providing valuable insight and parametric quantities for further engineering analysis. The classical modeling approach is to fit the probability ...

Novel Models for Hourly Solar Radiation Using a 2-D Approach
(Icic Int, 2009)
In this work one year hourly solar radiation data are analyzed and modeled using a novel visualization method. Using a 2-D(Dimensional) surface fitting approach, the general behavior of the solar radiation in a year is ...
Steepest Descent Algorithm For Block Wavelet Transform Filter Coefficients That Generate Orthogonal Transform Matrix
(IEEE, 2008)
It's known that the transform matrix generated by Block Wavelet Transform (BWT) is orthogonal. Eigenvector matrix of the autocorrelation matrix obtained in Karhunen-Loeve transform is also orthogonal. This matrix is used ...
Covariance analysis of voltage waveform signature for power-quality event classification
(IEEE-Inst Electrical Electronics Engineers Inc, 2006)
In this paper, covariance behavior of several features (signature identifiers) that are determined from the voltage waveform within a time window for power-quality (PQ) event detection and classification is analyzed. A ...
Segmentaton performance comparison over HDR images [YDA Görüntülerde Bölütleme Algoritmalarinin Performans Karşilaştirmasi]
(Institute of Electrical and Electronics Engineers Inc., 2015)
Achievement of sharp, crisp and contrasty photos plays an important role in automatic image segmentation. A fair contrast can be achieved by successful exposure settings in the camera, which can be difficult to achieve ...
Circular Uncertainty method for range-only localization with imprecise sensor positions
(Springer, 2018)
This study provides an effective new method to solve the range-only localization in the presence of sensor position errors. In practice, the sensors can stay only within a limited region whereas the target can be far from ...
