    • A fuzzy AHP approach to evaluating machine tool alternatives 

      Ayağ, Zeki; Özdemir, Rifat Gürcan (SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2006-04)
      Selecting process of a machine tool has been very important issue for companies for years, because the improper selection of a machine tool might cause of many problems affecting negatively on productivity, precision, ...
    • An Intelligent Approach To Machine Tool Selection Through Fuzzy Analytic Network Process 

      Ayağ, Zeki; Özdemir, Rifat Gürcan (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2011-04)
      In this study, we utilize analytic network process (ANP), a more general form of AHP, for justifying stand-alone machine tools out of available alternatives in market due to the fact that AHP cannot accommodate the variety ...
    • On The Evolution Of Anomalous X-Ray Pulsars And Soft Gamma-Ray Repeaters Wıth Fall Back Disks 

      Ertan, Ünal; Ekşi, Kazım Yavuz; Erkut, Mehmet Hakan; Alpar, Mehmet Ali (Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2009-09-10)
      We show that the period clustering of anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), their X-ray luminosities, ages, and statistics can be explained with fall back disks with large initial specific ...
    • Raman Micro-Spectroscopic Analysis of Cultured HCT116 Colon Cancer Cells in The Presence of Roscovitine 

      Akyüz, Sevim; Özel, Ayşen; Balcı, Kubilay; Akyüz, Zeki Tanıl; Çoker, Ajda; Arısan, Elif Damla; Palavan-Ünsal, Narçin; Özalpan, Atilla (Pergamon-Elsevier Science Ltd, The Boulevard, Langford Lane, Kidlington, Oxford Ox5 1Gb, England, 2011-05)
      Raman micro-spectroscopic analysis of cultured HCT116 colon cancer cells in the presence of roscovitine, [seliciclib, 2-(1-ethyl-2-hydroxy-ethylamino)-6-benzylamino-9-isopropylpurine], a promising drug candidate in cancer ...
    • Solution of counter diffusion problem with position dependent diffusion coefficent by using variational methods 

      Yüksek, Kemal; Koca, Yeliz; Sadıkoğlu, Hasan (ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 2009-10-15)
      Unsteady state counter diffusion problem with position dependent diffusion coefficient can be modeled using Fick's second law. A mathematical model was constructed and solved to quantitatively describe the dynamic behavior ...
    • The Effect Of Activity-Related Meridional Flow Modulation On The Strength Of The Solar Polar Magnetic Field 

      Jiang, J.; Işık, Emre; Cameron, R. H.; Schmitt, D.; Schuessler, M. (Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2010-07-01)
      We studied the effect of the perturbation of the meridional flowin the activity belts detected by local helioseismology on the development and strength of the surface magnetic field at the polar caps. We carried out ...
