Object reconstruction from in-line Fresnel holograms without explicit depth focusing
(Spie-Int Society Optical Engineering, 2004)We propose two computational techniques for extracting object cross-sectional shape information from digitized in-line Fresnel holograms that do not require prior knowledge of object depths but recover relative depth ... -
On the existence of a disk algebra basis
(Elsevier Science BV, 2000)In this paper, approximation of discrete-time systems by fixed pole orthonormal basis functions is investigated. It is shown that if accumulation points of basis poles do not cover the entire unit circle, then the Fourier ... -
On the realization of common matrix classifier using covariance tensors
(Academic Press Inc Elsevier Science, 2015)Due to the growing interest in image classifiers, the concept of native two dimensional (2-D) classifiers continues to attract researchers in the field of pattern recognition. In most cases, the 2-D extension of a regular ... -
On the uniform approximation of discrete-time systems by generalized Fourier series
(IEEE-Inst Electrical Electronics Engineers Inc, 2001)In this paper, model sets for linear time-invariant discrete-time systems spanned by fixed orthonormal bases are studied. It is shown that the Fourier series of the system transfer function with respect to these bases ... -
Overlapping decompositions and expansions of Petri nets
(IEEE-Inst Electrical Electronics Engineers Inc, 2002)Overlapping decompositions and expansions are considered to design decentralized controllers for discrete-event systems (DESs) modeled, by Petri nets. The inclusion principle for Petri nets is first defined. It is shown ... -
Overlapping decompositions, expansions, contractions, and stability of hybrid systems
(IEEE-Inst Electrical Electronics Engineers Inc, 1998)Inclusion and extension principles are defined and studied for hybrid systems, The controller design problem for hybrid systems is then considered within the framemork of the extension principle. It is shown that if the ... -
Paley inequalities for discrete-time rational orthonormal bases
(Elsevier Science BV, 2000)In this paper, we derive some inequalities which provide information about the Fourier coefficients of linear-time-invariant discrete-time systems with respect to the bounded rational orthonormal basis functions studied ... -
A path selection-based algorithm for real-time data staging in Grid applications
(Academic Press Inc Elsevier Science, 2005)Efficient data scheduling is becoming an important issue in distributed real-time applications that produce huge data sets. The Grid environment on which these applications may run seeks to harness the geographically ... -
Performance and Robustness of Flow Controllers Designed Using Non-causal Uncertainty Blocks
(Wiley, 2013)According to some recent results, use of non-causal uncertainty blocks may be advantageous in the robust controller design of systems with multiple uncertain time-delays. In this work, performance and robustness improvements ... -
Performance level and stability margins of an optimal H-infinity flow controller
(SAGE Publications LTD, 2012)Flow controllers are needed to avoid congestion in different types of networks. The dynamics of such networks, however, can usually be represented by infinite-dimensional models, which are either based on partial-differential ... -
A Perturbation Method for Scattering by a Dielectric Cylinder Buried in a Half-Space
(IEEE-Inst Electrical Electronics Engineers Inc, 2018)A simple method is presented for transverse magnetic plane-wave scattering by a dielectric cylinder of arbitrary cross section buried in a half-space. The interface between two semi-infinite dissimilar half-spaces is ... -
