Period estimation of an almost periodic signal using persistent homology with application to respiratory rate measurement

Erden, F.; Çetin, A. Enis (Institute of Electrical and Electronics Engineers Inc., 2017)

Time-frequency techniques have difficulties in yielding efficient online algorithms for almost periodic signals. We describe a new topological method to find the period of signals that have an almost periodic waveform. ...
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 ...
