Fault Detection in Induction Motors with Independent Component Analysis (ICA)
Guney, Irfan; Kilic, Erdal; Ozgonenel, Okan; Ulutas, Mustafa; Karadeniz, Erol (Ieee, 2009)In this study, the aim is to detect an induction motor's winding faults by using independent component analysis (ICA). Many laboratory experiments have been done on an induction motor to check the performance of the proposed ... -
Fault identification in transformers through a fuzzy discrete event system approach
Kilic, Erdal; Ozgonenel, Okan; Ulutas, Mustafa (Ieee, Electron Devices Soc & Reliability Group, 2007)A new fault detection and identification (FDI) scheme for transformer faults are suggested in this paper. The new method is based on fuzzy discrete event, from now FDES, composed from between a transformer's measured outputs ... -
Polynomial Approach in a Secret Image Sharing Using Quadratic Residue
Ulutas, Guzin; Nabiyev, Vasif V.; Ulutas, Mustafa (Ieee, 2009)Secret Image Sharing is a technique to share the secret among n participants. Each participant has meaningless, noise like shares. The secret image is revealed if any k of the shares are gathered. This scheme uses polynomial ... -
A PVSS Scheme Based on Boolean Operations with Improved Contrast
Ulutas, Mustafa; Nabiyev, Vasif V.; Ulutas, Guzin (Ieee, 2009)Visual Secret Sharing (VSS) is a method to encode a secret image into multiple shares. Coding one pixel of secret image into m sub-pixels in shares during encoding process causes pixel expansion problem. Probabilistic ... -
Secret Image Sharing Scheme Based on HS-TS Geometric Method
Ulutas, Mustafa; Nabiyev, Vasif V.; Ulutas, Guezin (Ieee, 2009)In 1979, Blakley and Shamir proposed a new concept called secret sharing based on dividing the secret among n participants. This method, also called the (t, n) threshold scheme, requires at least I of the n participants ... -
Steganography Based on Reduced Dynamic Range Subimage Intensity Variation
Ulutas, Mustafa; Nabiyev, Vastif V.; Ulutas, Guezin (Ieee, 2008)Hiding data in a medium such that it can not be perceived easily is called Steganography. Two of the most important performance metrics, of steganography are the embedding capacity and noticeability. Specific features of ...
