Aliasing probability calculations in nonlinear compactors
(2003)This paper discusses a systematic methodology for calculating the aliasing probability when an arbitrary finitestate machine is used to compact the response of a combinational circuit to a sequence of randomly generated ...

Bounds on FSM switching activity
(2008)This paper obtains lower and upper bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven by typical input sequences. More specifically, the paper provides bounds on the average ...

Conditional densities for continuoustime nonlinear hybrid systems with applications to fault detection
(1999)Continuoustime nonlinear stochastic differential state and measurement equations, all of which have coefficients capable of abrupt changes at a random time, are considered; finitestate jump Markov chains are used to model ...

A convex programming approach to the multiobjective H2/H∞ problem
(2002)In this paper, Banach space duality theory for the multiobjective H2/H∞ problem developed recently by the authors, is used to develop algorithms to solve this problem by approximately reducing the dual and predual ...

Current transport in semiconductor nanowires with builtin barriers based on a 1D transfer matrix calculation
(2008)A one dimensional (1D) transfer matrix calculation of current transport in semiconductor nanowires with builtin barriers is described within the effective mass approximation by taking into account (i) the quantum confinement ...

Delayed observers for linear systems with unknown inputs
(2007)We present a method for constructing reducedorder state observers for linear systems with unknown inputs. Our approach provides a characterization of observers with delay, which eases the established necessary conditions ...

Distributed function calculation and consensus using linear iterative strategies
(2008)Given an arbitrary network of interconnected nodes, we develop and analyze a distributed strategy that enables a subset of the nodes to calculate any given function of the node values. Our scheme utilizes a linear iteration ...

Encoded finitestate machines for nonconcurrent error detection and identification
(2003)In this paper we develop a methodology for systematically constructing redundant finitestate machines in a way that enables an external mechanism to detect and identify transient statetransition faults by performing ...

Exact filters for NewtonRaphson parameter estimation algorithms for continuoustime partially observed stochastic systems
(IEEE, 1999)This paper presents explicit finitedimensional filters for implementing NewtonRaphson (NR) parameter estimation algorithms. The models which exhibit nonlinear parameter dependence are stochastic, continuoustime and ...

Fault detection and identification in Petri net controllers
(2004)This paper proposes a methodology for providing fault tolerance to Petri net controllers. In order to provide tolerance against faults that may compromise the functionality of the Petri net controller, we construct a ...

Faulttolerant discretetime linear timeinvariant 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 faulttolerant ...

Article
Faulttolerant dynamic systems
(2000)We use unreliable system replicas and unreliable voters to construct redundant dynamic systems that tolerate transient failures in their state transition and error correcting mechanisms. Using low density parity check ...

Filtering for linear systems driven by fractional Brownian motion
(2003)In this paper we study continuous time filtering for linear multidimensional systems driven by fractional Brownian motion processes. We present the derivation of the optimum linear filter equations which involve a pair of ...

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

Hierarchical decentralized fusion from correlated sensor measurements
(2005)In this paper we consider hierarchical decentralized fusion of possibly correlated noisy measurements of a random variable. Our goal is to obtain initial estimates in a decentralized fashion (based on disjoint groupings ...

Information capacity of MIMO channels with relative entropy constraint
(2006)This paper addresses the issue of multipleinput multipleoutput (MIMO) wireless channel capacity, when the probability distribution of the channel matrix p(H) is not completely known to the transmitter and the receiver. ...

Information states in stochastic control and filtering: a lie algebraic theoretic approach
(2000)The purpose of this paper is twofold: i) to introduce the sufficient statistic algebra which is responsible for propagating the sufficient statistics, or information state, in the optimal control of stochastic systems and ...
