  • Re-mining item associations: Methodology and a case study in apparel retailing 
    Demirer, Ahmet; Kula, Ufuk; Demiriz, Ayhan (ELSEVIER SCIENCE BV, 2011)
    Association mining is the conventional data mining technique for analyzing market basket data and it reveals the positive and negative associations between items. While being an integral part of transaction data, pricing ...
  • Structural optimization with CADO method for a three-dimensional sheet-metal vehicle body 
    Çalışkan, Mehmet; Uçar, Vahdet (ELSEVIER SCIENCE BV, 2011)
    The aim of this study is to increase power/weight ratio of a steel-alloyed vehicle body without any structural weakness and to use an integrated engineering solution of "computer-aided design, engineering and optimization ...
  • The Hyperfine Structure Calculations of Some Excited Levels for La-139 I 
    Usta, Betül; Özdemir, Leyla (POLISH ACAD SCIENCES INST PHYSICS, 2009)
    We calculated hyperfine structure constants of the 5d6s(2), 5d(2)6s, 5d(3), 5d(2)7s, 5d6s7s, 5d6p(2), 4f(2)5d, 4f6s6p, 5d6s6p, 5d(2)6p, 4f5d6s and 4f5d(2) levels for La-139 I (Z = 57). The calculations are based upon the ...
  • The level structure of atomic lutetium (Z=71): a relativistic Hartree-Fock calculation 
    Usta, Betül; Özdemir, Leyla (INDIAN ASSOC CULTIVATION SCIENCE, 2011)
    We have calculated relativistic energies, Land, factors and lifetimes for 5d6s (2), 5d (2)6s, 6s (2) ns (n = 7-14), 6s (2) nd (n = 6-25), 6s (2) ng (n = 5-7), 6s (2) np (n = 6-25), 5d6s6p and 6s (2) nf (n = 5-23) excited ...
  • The level structure of singly-ionized actinium 
    Ürer, Güldem; Özdemir, Leyla (KOREAN PHYSICAL SOC, 2012)
    We have presented a multiconfiguration Dirac-Fock (MCDF) study in the framework of Breit and quantum electrodynamic (QED) effects on the low-lying level structure of singly-ionized actinium (Ac II). The computations have ...
  • The Study of Exchange Bias Effect in PtxCo1-x/CoO Bilayers 
    Erkovan, Mustafa; M. E. Akoz; U. Parlak; Öztürk, Oğuzhan (SPRINGER, 2017)
    We investigated the exchange bias effect in PtxCo1-x/CoO bilayers as a function of Pt concentration. Chemical analysis on the Pt Co-x(1-x) layer confirmed that x varies from 0.6 to 0.9 by 0.1 step. Hereby, we present ...
  • Transition Energies of Lutetium 
    Usta, Betül; Özdemir, Leyla (PHYSICAL SOC REPUBLIC CHINA, 2012)
    Transition energies of neutral lutetium (Lu I, Z = 71) belonging to the lanthanide series, including the ionization potential, excitation energies, and electron affinity, are calculated by the multiconfiguration Hartree-Fock ...
  • Transition energies of neutral and singly ionized lanthanum 
    Usta, Betül; Özdemir, Leyla (INDIAN ASSOC CULTIVATION SCIENCE, 2010)
    We have calculated the transition energies (ionization potential, excitation energies, electron affinity) of neutral lanthanum (La I) and singly ionized lanthanum (La II). The calculations are based upon the multiconfiguration ...
  • Transition Energies of Ytterbium (Z=70) 
    Usta, Betül; Özdemir, Leyla (VERLAG Z NATURFORSCH, 2011)
    Transition energies of neutral ytterbium (Yb I, Z = 70, belonging to the lanthanide series), including ionization potential, excitation energies, and electron affinity are calculated by the multiconfiguration Hartree-Fock ...
  • Transition Parameters for Doubly Ionized Lutetium 
    Usta, Betül; Özdemir, Leyla (POLISH ACAD SCIENCES INST PHYSICS, 2013)
    Using the relativistic Hartree-Fock method developed by Cowan, we calculated the electric dipole (E1) transition parameters such as the wavelengths, the weighted oscillator strengths, and the transition probabilities (or ...
