Classification of power quality disturbances at power system frequency and out of power system frequency using support vector machines
Arikan Ç.; Özdemir M. (Wydawnictwo SIGMA - N O T Sp. z o.o., 2013)In this paper, firstly it is tried to classify pure sine and power quality disturbances (PQD) such as voltage sag, voltage swell, voltage with harmonics, transients and flicker at power system frequency (50 Hz). Wavelet ... -
Classification of power quality disturbances using support vector machines and comparing classification performance
Arikan Ç.; Özdemir M. (Praise Worthy Prize S.r.l, 2013)In this study pure sine and five kinds of power quality disturbances (PQD) such as voltage swell, voltage sag, voltage with harmonics, transients and flicker are classified by using wavelet based support vector machines ... -
Comparison of statistical methods and wavelet energy coefficients for determining two common PQ disturbances: Sag and well
Kocaman Ç.; Özdemir M. (2009)This paper presents statistical methods and wavelet based effective feature extraction method for power quality (PQ) disturbance classification problem. The PQ signals used in this study are two common types named as swell ... -
Desulfurization of two Turkish lignites by chlorinolysis
Özdemir M.; Bayrakçeken S.; Gürses A.; Gülaboúlu Ş. (1990)The desulfurization of two Turkish lignites by chlorinolysis with chlorine gas in carbon tetrachloride in the presence of water and at ambient pressure was examined. Almost all of the inorganic sulfur, and a significant ... -
Determining five kinds of power quality disturbances by using statistical methods and wavelet energy coefficients
Kocaman Ç.; Özdemir M. (European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2017)In this paper, it is tried to compare two methods for determining pure sine and five kinds of power quality disturbances (PQD) such as voltage sag, voltage swell, voltage with harmonics, transients and flicker. These methods ... -
Effect of the environmental temperature on the degradation period of carbaryl
Uyanik A.; Özdemir M. (TUBITAK, 1999)In this study, the effect of the temperature on the degradation period of Carbaryl (Sevin), a widely used outdoor and indoor insecticide, was investigated in a laboratory in soil and on green plants by using a new quantitative ... -
Modelling and simulation of a series excited synchronous motor
Özdemir M.; Önbilgin G. (2001)This study attempts to build up a mathematical model, for a type af series excited synchronous motor. This model, when used for simulation, is expected to yield the dynamic behaviour of the system for typical cases such ... -
A new wind power measurement algorithm: A sample calculation for OMU-Dedebuzagi hill
Kolsan Ö.; Ozgonenel O.; Özdemir M.; Karaca S. (2012)In this work, both unscented transform (UT) and frequency analysis techniques are used for calculating potential wind power of OMU - Dedebuzagi hill based on a year wind data. UT technique reduces process time since it ... -
Non-syndromic familial unerupted teeth: A rare contidion
Sener I.; Turer A.; Bereket C.; Özdemir M. (Cumhuriyet University Faculty of Dentistry, 2015)A tooth that remains unerupted beyond the normal time of eruption and fails to erupt is called an impacted tooth. Maxillofacial surgeons encounter the problem of impacted teeth very often. Usually, impacted teeth involve ... -
A novel one-pot synthesis of heterocyclic compound (4-benzoyl-5-phenyl-2-(pyridin-2-yl)-3,3a-dihydropyrazolo[1,5-c]pyrimidin-7(6H)-one): Structural (X-ray and DFT) and spectroscopic (FT-IR, NMR, UV-Vis and Mass) characterization Studies
Özdemir M.; Sönmez M.; Şen F.; Dinçer M.; Özdemir N. (Elsevier B.V., 2015)In this study, the title compound named as 4-benzoyl-5-phenyl-2-(pyridin-2-yl)-3,3a-dihydropyrazolo[1,5-c]pyrimidin-7(6H)-one (C24H18N4O2) was both experimentally and theoretically investigated. The compound was synthesized ... -
The structure and analysis of a hybrid compensation system
Dirik H.; Özdemir M.; Kocaman Ç. (2010)In this work, by using a classic electromechnical controlledcapacitor switched compensation system combined with DStatcom (which is a shunt compansator), it is aimed to improve the reactive power compensation of loads. In ...
