      Fault-tolerant discrete-time linear time-invariant filters 

      Hadjicostis, Christoforos N. (Institute of Electrical and Electronics Engineers Inc., 2000)
      Modular redundancy, the traditional approach to fault tolerance, is prohibitively expensive because of the overhead in replicating the hardware. In this paper we discuss alternative methods for obtaining fault-tolerant ...

      A meshless numerical identification of a sound-hard obstacle 

      Karageorghis, Andreas; Lesnic, D. (2012)
      We propose a simple meshless method for detecting a rigid (sound-hard) scatterer embedded in a host acoustic homogeneous medium from scant measurements of the scattered near field. This inverse problem is ill-posed since ...
