    • Analysis of reactive scheduling problems in a job shop environment 

      Sabuncuoğlu, İ.; Bayız, M. (Elsevier, 2000)
      In this paper, we study the reactive scheduling problems in a stochastic manufacturing environment. Specifically, we test the several scheduling policies under machine breakdowns in a classical job shop system. In addition, ...
    • Asymptotic wave-like modeling of dielectric lenses 

      Yurchenko V.B.; Itintas, A.A. (2007)
      We propose asymptotic wave-like approximations for the accurate modeling of dielectric lenses used in quasi-optical systems of millimeter, submillimeter, and infrared wave applications. For the comparison, we obtain an ...
    • Capital maintenance as a key development tool 

      Boucekkine, R.; Martinez, B.; Saglam, C. (Wiley-Blackwell Publishing Ltd., 2010)
      We construct optimal growth models where labor resources can be allocated either to production, technology adoption or capital maintenance. We first characterize the balanced growth paths of a benchmark model without ...
    • Fault-tolerant irregular topology design method for network-on-chips 

      Tosun, S.; Ajabshir V.B.; Mercanoglu O.; Ozturk, O. (Institute of Electrical and Electronics Engineers Inc., 2014)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Fault-tolerant topology generation method for application-specific network-on-chips 

      Tosun, S.; Ajabshir, V. B.; Mercanoglu, O.; Ozturk, O. (Institute of Electrical and Electronics Engineers, 2015)
      As the technology sizes of integrated circuits (ICs) scale down rapidly, current transistor densities on chips dramatically increase. While nanometer feature sizes allow denser chip designs in each technology generation, ...
    • Graph aware caching policy for distributed graph stores 

      Aksu H.; Canim, M.; Chang, Y.-C.; Korpeoglu I.; Ulusoy Ö. (Institute of Electrical and Electronics Engineers Inc., 2015)
      Graph stores are becoming increasingly popular among NOSQL applications seeking flexibility and heterogeneity in managing linked data. Conceptually and in practice, applications ranging from social networks, knowledge ...
    • Hypergraph-theoretic partitioning models for parallel web crawling 

      Turk, A.; Cambazoglu, B.B.; Aykanat, C. (2012)
      Parallel web crawling is an important technique employed by large-scale search engines for content acquisition. A commonly used inter-processor coordination scheme in parallel crawling systems is the link exchange scheme, ...
    • ISO 9000 implementation in Turkish industry 

      Erel, E.; Ghosh, J. B. (Emerald, 1997)
      Notes that it has become a competitive necessity for firms doing business globally to acquire the ISO 9000 certification, despite the misgivings many have with regard to its true effectiveness. Turkey, an emerging industrial ...
    • Moving shadow detection in video using cepstrum 

      Cogun, F.; Cetin, A. E. (SAGE, 2013)
      Moving shadows constitute problems in various applications such as image segmentation and object tracking. The main cause of these problems is the misclassification of the shadow pixels as target pixels. Therefore, the use ...
    • Optimal and suboptimal receivers for code-multiplexed transmitted-reference ultra-wideband systems 

      Tutay, M. E.; Gezici, S. (Wiley, 2013)
      In this study, optimal and suboptimal receivers are investigated for code-multiplexed transmitted-reference (CM-TR) ultra-wideband systems. First, a single-user scenario is considered, and a CM-TR system is modeled as a ...
    • Physical optics modeling of 2D dielectric lenses 

      Yurchenko, V. B.; Altintas, A. (Optical Society of America, 2009-01-27)
      We propose an advanced physical optics formulation for the accurate modeling of dielectric lenses used in quasi-optical systems of millimeter, submillimeter, and infrared wave applications. For comparison, we obtain an ...
    • Strategic alignment and new product development: drivers and performance effects 

      Acur, N.; Kandemir, D.; Boer H. (Wiley-Blackwell Publishing, 2012)
      Strategic alignment is widely accepted as a prerequisite for a firm's success, but insight into the role of alignment in, and its impact on, the new product development (NPD) process and its performance is less well ...
    • Structuring research on conformal antennas a European collaboration 

      Sipus, Z.; Persson, P.; Lanne, M.; Heckler, M.; Maci, S.; Campos, J. L. M.; Knott, P.; Ertürk, V.; Vandenbosch, G. (2007)
      The topic of this paper is the work carried out within work package 2.4-3 of the EU network "antenna centre of excellence" (ACE). This work package is concerned with structuring research on conformal antennas. In particular, ...
    • Sulfur-tolerant BaO/ZrO2/TiO2/Al2O3 quaternary mixed oxides for deNOX catalysis 

      Say, Z.; Mihai, O.; Tohumeken, M.; Ercan, K. E.; Olsson, L.; Ozensoy, E. (Royal Society of Chemistry, 2017)
      Advanced quaternary mixed oxide materials in the form of BaO/Al2O3/ZrO2/TiO2 functionalized with Pt active sites (i.e. Pt/BaO/AZT) were synthesized and structurally characterized via XRD and BET in comparison to a ...
    • Throughput modeling of single hop CSMA networks with non-negligible propagation delay 

      Koseoglu, M.; Karasan, E. (IEEE, 2013)
      We analyze the performance of the CSMA protocol under propagation delays that are comparable with packet transmission times. We propose a semi-Markov model for the 2-node CSMA channel. For the 2-node case, the capacity ...
