      Dynamic count filters 

      Aguilar-Saborit, J.; Trancoso, Pedro; Muntes-Mulero, V.; Larriba-Pey, J. L. (2006)
      Bloom filters are not able to handle deletes and inserts on multisets over time. This is important in many situations when streamed data evolve rapidly and change patterns frequently. Counting Bloom Filters (CBF) have been ...

      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 ...

      Nonconcurrent error correction in the presence of roundoff noise 

      Takos, G.; Hadjicostis, Christoforos N. (2009)
      This paper analyzes the effects of roundoff noise on our ability to nonconcurrently detect and identify transient faults that corrupt state variables during the operation of a fault-tolerant discrete-time linear time-invariant ...
