    • Analysis of design parameters in SIL-4 safety-critical computer 

      Ahangari, Hamzeh; Özkök, Y. I.; Yıldırım, A.; Say, F.; Atik, Funda; Öztürk, Özcan (IEEE, 2017-01)
      Nowadays, Safety-critical computers are extensively used in may civil domains like transportation including railways, avionics and automotive. We noticed that in design of some previous works, some critical safety design ...

    • Computational methods for risk-averse undiscounted transient markov models 

      Çavuş, O.; Ruszczyński, A. (Institute for Operations Research and the Management Sciences (I N F O R M S), 2014)
      The total cost problem for discrete-time controlled transient Markov models is considered. The objective functional is a Markov dynamic risk measure of the total cost. Two solution methods, value and policy iteration, are ...

    • Cost-effectiveness of adjuvant FOLFOX and 5FU/LV chemotherapy for patients with stage II colon cancer 

      Ayvaci, M.U.S.; Shi J.; Alagoz O.; Lubner, S.J. (2013)
      Purpose. We evaluated the cost-effectiveness of adjuvant chemotherapy using 5-fluorouracil, leucovorin (5FU/LV), and oxaliplatin (FOLFOX) compared with 5FU/LV alone and 5FU/LV compared with observation alone for patients ...

    • A robust system for counting people using an infrared sensor and a camera 

      Erden, F.; Alkar, A. Z.; Cetin, A. E. (Elsevier BV, 2015)
      In this paper, a multi-modal solution to the people counting problem in a given area is described. The multi-modal system consists of a differential pyro-electric infrared (PIR) sensor and a camera. Faces in the surveillance ...

    • VOC gas leak detection using pyro-electric infrared sensors 

      Erden, Fatih; Soyer, E. B.; Toreyin, B. U.; Çetin, A. Enis (IEEE, 2010)
      In this paper, we propose a novel method for detecting and monitoring Volatile Organic Compounds (VOC) gas leaks by using a Pyro-electric (or Passive) Infrared (PIR) sensor whose spectral range intersects with the absorption ...

    • Wavelet based flame detection using differential PIR sensors 

      Erden F.; Töreyin, B.U.; Soyer, E.B.; Inaç I.; Günay O.; Köse, K.; Çetin, A.E. (2012)
      In this paper, a flame detection system using a differential Pyro-electric Infrared (PIR) sensor is proposed. A differential PIR sensor is only sensitive to sudden temperature variations within its viewing range and it ...
