    • Economic design of EWMA control charts based on loss function 

      Serel, D. A. (Elsevier, 2009)
      For monitoring the stability of a process, various control charts based on exponentially weighted moving average (EWMA) statistics have been proposed in the literature. We study the economic design of EWMA-based mean and ...

    • Evaluate of braze joint strength and microstructure characterize of titanium-CP with Ag-based filler alloy 

      Ganjeh, E.; Sarkhosh H.; Khorsand H.; Sabet H.; Dehkordi, E.H.; Ghaffari, M. (2012)
      This research investigates the influences of brazing parameters (temperature and time) on microstructures and the mechanical properties of commercially pure (CP) titanium sheet when it is brazed with CBS34 (Ag-20Cu-22Zn-24Cd) ...

    • Exploiting index pruning methods for clustering XML collections 

      Altıngövde, İsmail Şengör; Atılgan, Duygu; Ulusoy, Özgür (Springer, Berlin, Heidelberg, 2010)
      In this paper, we first employ the well known Cover-Coefficient Based Clustering Methodology (C3M) for clustering XML documents. Next, we apply index pruning techniques from the literature to reduce the size of the document ...

    • Investigation on braze joint strength and microstructure of Ti-CP with Ag and Ti base filler alloys 

      Ganjeh, E.; Khorsand H.; Sarkhosh H.; Ghaffari, M.; Sabet H.; Dehkordi, E.H. (American Welding Society, 2012)
      This research investigates influences of brazing parameters (brazing alloy, temperature and time) on microstructures and mechanical properties of a commercially pure (CP) titanium sheet which is brazed with CBS 34 (Ag-based) ...

    • Investing in quality under autonomous and induced learning 

      Serel, D. A.; Dada, M.; Moskowitz, H.; Plante, R. D. (Taylor & Francis, 2003)
      The reduction of variability in product performance characteristics is an important focus of quality improvement programs. Learning is intrinsically linked to process improvement and can assume two forms: (i) autonomous ...

    • Optimization of the gain-bandwidth product of capacitive micromachined ultrasonic transducers 

      Olcum, S.; Senlik, M. N.; Atalar, Abdullah (IEEE, 2005-12)
      Capacitive micromachined ultrasonic transducers (cMUT) have large bandwidths, but they typically have low conversion efficiencies. This paper defines a performance measure in the form of a gain-bandwidth product and ...

    • Quality control chart design under jidoka 

      Berk, E.; Toy, A. Ö. (John Wiley & Sons, Inc., 2009)
      We consider design of control charts in the presence of machine stoppages that are exogenously imposed (as under jidoka practices). Each stoppage creates an opportunity for inspection/repair at reduced cost. We first model ...

    • Source and filter estimation for Throat-Microphone speech enhancement 

      Turan, M. A. T.; Erzin, E. (Institute of Electrical and Electronics Engineers Inc., 2016)
      In this paper, we propose a new statistical enhancement system for throat microphone recordings through source and filter separation. Throat microphones (TM) are skin-attached piezoelectric sensors that can capture speech ...

    • Univariate X̄ control charts for individual characteristics in a multinormal model 

      Serel, D. A.; Moskowitz, H.; Tang, J. (Taylor & Francis, 2000)
      The early work on multivariate statistical process control was built upon Hotelling's T2 control chart which was developed to simultaneously monitor the means of correlated quality variables. This chart, however, has a ...
