  • Rewriting XPath queries using materialized XPath views
    Ramanan, Prakash (Elsevier, 2012-07)
    Let XP(/, //, []) be the fragment of XPath 1.0, consisting of queries that involve only the child and descendant axes, and predicates without disjunction or negation (and no wildcard nodetests); these queries can be ...
  • RFID security threats to consumers: Hype vs. reality
    Rao, Shantanu; Thanthry, Nagaraja; Pendse, Ravi (IEEE, 2007-10-08)
    Radio frequency identification (RFID) tags are being adopted rapidly by retail giants such as Wal-Mart In the near future these tags will be used for item level tracking of consumer products such as milk cartons, television ...
  • Robustness of sampled-data control to unmodeled high-frequency dynamics
    Dinh, Joseph H.; Sawan, M. Edwin (IEEE, 1993-06-02)
    Robustness of sampled-data control designs to unmodeled high-frequency dynamics is studied using singular perturbation theory. When a plant is preceded by a zero-order holder, a direct transmission term of the reduced-order ...
  • A robust observer-based model-following control
    Moursi, Z. M.; Raptis, J.; Sawan, M. Edwin (IEEE, 1988-06-15)
    The model-following problem has been expressed as an LQ-problem, and robustness achieved by including an exponential factor in the cost integrand. In this paper the observer-based case is considered and the inherent ...
  • Robust performance design of PID controllers with inverse multiplicative uncertainty
    Emami, Tooran; Watkins, John Michael (IEEE, 2011-06-29)
    In this paper a graphical method is introduced for finding all proportional integral derivative (PID) controllers that satisfy a robust performance constraint for a given single input-single-output (SISO) linear time ...
  • Route optimized nested mobility solution using PAT
    Dattani, M.; Thanthry, Nagaraja; Best, Tish; Bhagavathula, Ravi; Pendse, Ravi (IEEE, 2004-09-26)
    Mobile computing is becoming increasingly important due to the rise in the number of portable computers and the desire to have continuous network connectivity to the Internet, irrespective of the physical location of the ...
  • RRQR based closed-form blind carrier offset estimator for OFDM systems
    Qasaymeh, M.M.; Nizar, T.; Hiren, G.; Sawan, M. Edwin; Pendse, Ravi (IEEE, 2009-05-25)
    Carrier Frequency Offset (CFO) is one of the major drawbacks of the Multi Carrier Modulation (MCM) technique. Blind, semiblind and data-aided techniques have been introduced to estimate the CFO. In this paper, a new blind ...
  • Scalable QoS provisioning for mobile networks using wireless sensors
    Bahety, V.; Pendse, Ravi (IEEE, 2004-03-21)
    In the past few years support for mobility has increased to a large extent. Mobile IP enables nodes to move from one network to the other while maintaining the same IP address. Minimal packet loss during handoff is a ...
  • Secure, redundant, and fully distributed key management scheme for mobile ad hoc networks: An analysis
    Joshi, Deepti; Namuduri, Kameswara; Pendse, Ravi (Hindawi Publishing Corporation, 2005-05)

  • Selective prefetching: prefetching when only required
    Pendse, Ravi; Katta, H. (IEEE, 1999)
    Cache memories are commonly used to reduce the number of slower lower-level memory accesses, thereby improving the memory hierarchy performance. However, high cache miss-ratio can severely degrade system performance. It ...
