    H ∞-filter based target tracking under time delayed measurements
    (IEEE, 2012) Ateş, Ezgi; Özbay, Hitay
    In this paper a new filter structure is proposed for the H ∞ estimation under delayed measurements for continuous time processes. As an example, target tracking problem is considered and results obtained from the classical H 2-optimal and the proposed H ∞-optimal filters are compared. © 2012 IEEE.

    VOC gas leak detection using pyro-electric infrared sensors
    (IEEE, 2010) Erden, Fatih; Soyer, E. B.; Toreyin, B. U.; Çetin, A. Enis
    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 bands of VOC gases. A continuous time analog signal is obtained from the PIR sensor. This signal is discretized and analyzed in real time. Feature parameters are extracted in wavelet domain and classified using a Markov Model (MM) based classifier. Experimental results are presented. ©2010 IEEE.
