A 2D representation for analysis and coding of power quality events
(IEEE, 2003)In this work, we demonstrate examples about uses of practical image processing techniques over a new interpretation of power quality event data. Power quality event data are 1D data obtained from a real life system with ... -
Frequency domain subispace-based identification of discrete-time power spectra from nonuniformly spaced measurements
(Pergamon-Elsevier Science LTD, 2004)In this paper, we present a new subspace-based algorithm for the identification of multi-input/multi-output, square, discrete-time, linear-time invariant systems from nonuniformly spaced power spectrum measurements. The ... -
The size of the membership-set in a probabilistic framework
(Pergamon-Elsevier Science LTD, 2004)In this paper, we study the size of the membership-set for system identification in a probabilistic framework. Assuming that the regressors are persistently exciting and the measurement noise is a sequence of independent, ... -
A study of random vibration characteristics of the quarter-car model
(Academic Press LTD Elsevier Science LTD, 2005)In this paper, the quarter-car model is used to study the response of the vehicle to profile imposed excitation with randomly varying traverse velocity and variable vehicle forward velocity. Root-mean-square response of ... -
Lossless image compression using an edge adapted lifting predictor
(IEEE, 2005)We present a novel and computationally simple prediction stage in a Daubechies 5/3 - like lifting structure for lossless image compression. In the 5/3 wavelet, the prediction filter predicts the value of an odd-indexed ... -
Decentralized supervisory controller design for discrete-event systems using overlapping decompositions and expansions
(Watam Press, 2004)A decentralized supervisory controller design approach for discrete-event systems (DESs) modeled by automata or formal languages is presented. The controller is designed in order to lead the DES to certain desired marked ... -
Robust tracking and disturbance rejection in linear hybrid systems
(Acta Press, 2005)Robust tracking and disturbance rejection problem, which is commonly referred as the robust servomechanism problem, is considered for linear hybrid systems. The necessary and sufficient conditions for the existence of a ... -
An integrated routing and flow control algorithm for data-communication networks
(Acta Press Anaheim, 2006)Routing and congestion control problems in data-communication networks are considered. A controller which acts both as a flow controller and a routing controller is presented. The controller is decentralized in the sense ... -
Algorithms for deadlock avoidance and reversibility enforcement in discrete event systems
(Watam Press, 2006)Discrete event systems which are modeled by automata are considered in this work. The algorithms which determine the set of deadlock states and the reversible set, and design the deadlock avoidance controller and the ... -
Centralized and decentralized supervisory controller design to enforce boundedness, liveness, and reversibility in Petri nets
(Taylor & Francis LTD, 2005)Supervisory controller design to enforce boundedness, liveness, and reversibility in Petri nets is considered. The Petri nets considered may have non-unity weight arcs and both controllable and uncontrollable transitions. ... -
Convergence analysis of central and minimax algorithms in scalar regressor models
(Springer London LTD, 2006)In this paper, the estimation of a scalar parameter is considered with given lower and upper bounds of the scalar regressor. We derive non-asymptotic, lower and upper bounds on the convergence rates of the parameter estimate ... -
A subspace-based method for solving Lagrange-Sylvester interpolation problems
(Siam Publications, 2007)In this paper, we study the Lagrange-Sylvester interpolation of rational matrix functions which are analytic at infinity, and propose a new interpolation algorithm based on the recent subspace-based identification methods. ... -
Synthesis of complete orthonormal fractional basis functions with prescribed poles
(IEEE-Inst Electrical Electronics Engineers Inc, 2008)In this paper, fractional orthonormal basis functions that generalize the well-known fixed pole rational basis functions are synthesized. For a range of noninteger differentiation orders and under mild restrictions on the ... -
An insight into instrumental variable frequency-domain subspace identification
(Pergamon-Elsevier Science LTD, 2010)In this paper, we study instrumental variable subspace identification of multi-input/multi-output linear-time-invariant, discrete-time systems from non-uniformly spaced frequency response measurements. A particular algorithm, ... -
Subspace-Based Rational Interpolation of Analytic Functions From Phase Data
(IEEE-Inst Electrical Electronics Engineers Inc, 2010)In this paper, two simple subspace-based identification algorithms to identify stable linear-time-invariant systems from corrupted phase samples of frequency response function are developed. The first algorithm uses data ... -
A study on performance of dynamic file replication algorithms for real-time file access in Data Grids
(Elsevier Science BV, 2009)Real-time Grid applications are emerging in many disciplines of science and engineering. In order to run these applications while meeting the associated real-time constraints with them, the Grid infrastructure should be ... -
Membership set identification with periodic inputs and orthonormal regressors
(Elsevier Science BV, 2006)In this paper, we study the central and the projection algorithms in membership-set estimation with periodic input signals and orthonormal basis functions for the special case that the number of the estimated parameters ... -
