Applications of minimum principle for continuous-time partially observable risk-sensitive control problems
(IEEE, 1995)This paper employs the minimum principle derived in [1], for nonlinear partially observable exponential of integral control problems, to solve linear-exponential-quadratic-Gaussian (LEQG) tracking problems using two different ...

Compact, linear, lead/lag phase shifters using negative refractive index metamaterials
(2003)A new type of phase shifter using cascaded sections of NRI metamaterials and PRI transmission lines is proposed, which offers some significant advantages over conventional delay lines. The phase shifter is compact in size, ...

Fault-tolerant discrete-time linear time-invariant filters
(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 ...

Finite-State Machine Embeddings for Non-Concurrent Error Detection and Identification
(2003)In digital sequential systems that operate over several time steps, a state-transition fault at any time step during the operation of the system corrupts its state in a way that can render its future functionality useless. ...

MIMO disturbance and plant uncertainty attenuation by feedback
(2002)This paper investigates the ability of feedback to reduce plant and disturbance uncertainties in the MIMO case, by solving two fundamental problems posed by Zames in the late seventies. The approach used here is Banach ...

Modeling change of haplotype distributions in random mating populations using random sets
(2004)Several mathematical models have been developed to describe the genetic structure of populations. Most of these models focus on only one, or few genetic loci. In this paper, we develop a model to describe a large number ...

Multiobjective H2/H∞ by banach space operator theory
(2001)In this paper Banach space duality theory and operator theory are combined to show that the optimal performance index in the multiobjective H2/H∞ is equal to the operator induced norm of a particular operator. This operator ...

Optimal merging algorithms for lossless codes with generalized criteria
(2014)This paper presents lossless prefix codes optimized with respect to a payoff criterion consisting of a convex combination of maximum codeword length and average codeword length. The optimal codeword lengths obtained are ...

A Perfect Reconstruction Paradigm for Digital Communication
(2003)In this paper we present a deterministic worst-case framework for reconstruction of discrete data transmissions through dispersive communication channels. This framework can be explored based on robust control ideas and ...

Relations between information theory, robustness, and statistical mechanics of stochastic systems
(2004)The fundamental question, which will be addressed in this talk are the relations between dissipation, which is a concept of robustness, entropy rate, which is a concept of information theory, and statistical mechanics. ...

Soft-decision decoding of linear block codes using multiple information bases
(2003)A previous study addressed algorithms that perform soft-decision decoding by utilizing encodings of test error patterns (TEPs) on the so-called "most reliable basis" which can be obtained by a greedy search algorithm. In ...

Soft-decision decoding of linear block codes using preprocessing
(2004)Two universally applicable preprocessing rules to improve iterative recoding algorithms, which utilize the most reliable basis (MRB), while focusing on order-w reprocessing, was investigated. The first preprocessing rule ...

Synchronization-based fault detection in discrete event systems
(2004)In this paper we study fault detection in systems that can be modeled as finite state machines (FSMs). We aim at detecting faults that manifest themselves as permanent changes in the next-state transition functionality of ...
