    • Assessment of information redundancy in ECG signals 

      Acar, Burak; Özçakır, Lütfü; Köymen, Hayrettin (IEEE, 1997-09)
      In this paper, the morphological information redundancy in standard 12 lead ECG channels is studied. Study is based on decomposing the ECG channels into orthogonal channels by an SVD based algorithm and then reconstructing ...
    • Diversity and novelty in information retrieval 

      Santos, R. L. T.; Castells, P.; Altıngövde, I. S.; Can, Fazlı (ACM, 2013-07-08)
      This tutorial aims to provide a unifying account of current research on diversity and novelty in different IR domains, namely, in the context of search engines, recommender sys- tems, and data streams.
    • Diversity and novelty in web search, recommender systems and data streams 

      Santos, R. L. T.; Castells, P.; Altingovde, I. S.; Can, Fazlı (Association for Computing Machinery, 2014-02)
      This tutorial aims to provide a unifying account of current research on diversity and novelty in the domains of web search, recommender systems, and data stream processing.
    • The effect of distribution of information on recovery of propagating signals 

      Karabulut, Özgecan (Bilkent University, 2015-09)
      Interpolation is one of the fundamental concepts in signal processing. The analysis of the di fficulty of interpolation of propagating waves is the subject of this thesis. It is known that the information contained in a ...
    • Motion-compensated prediction based algorithm for medical image sequence compression 

      Oǧuz, S. H.; Gerek, Ö. N.; Çetin, A. E. (Elsevier BV, 1995-09)
      A method for irreversible compression of medical image sequences is described. The method relies on discrete cosine transform and motion-compensated prediction to reduce intra- and inter-frame redundancies in medical image ...
    • A simulation study of two-level forward error correction for lost packet recovery in B-ISDN/ATM 

      Oğuz, Nihat Cem; Ayanoğlu, E. (IEEE, 1993)
      The major source of errors in B-ISDN/ATM systems is expected to be buffer overflow during congested conditions, resulting in lost packets. A single lost or errored ATM cell will cause retransmission of the entire packet ...
