Kılıç, Yasin Ozan; Aydın, Mehmet Nafiz (2009)As the enterprise systems increasingly use the XML technology in their data presentation, the Enterprise Application Integration is gradually becoming the problem of Xml Schema matching. Different organizations overall ... -
Behavior of quantum fisher information of bell pairs under decoherence channels
Özaydın, Fatih; Altıntaş, Azmi Ali; Buğu, Sinan; Yeşilyurt, Can (Polish Acad Sciences Inst Physics, 2014-02)Quantum Fisher information has recently been an essential tool for analyzing the phase sensitivity of the quantum states in various quantum tasks, requiring high precision, such as quantum clock synchronization, positioning ... -
Bifurcation of drift shells near the dayside magnetopause
Öztürk, Mehmet Kaan; Wolf, Richard A. (Amer Geophysical Union, 2007-07-10)Close to the dayside magnetopause, there is a region of space where each field line has two magnetic field minima, one near each cusp. That region is located around local noon, and extends about 1-2 R-e from the magnetopause. ... -
Co-registration of surfaces by 3D least squares matching
