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 ...

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 ...

Fault-tolerant 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 ...

Femtosecond dynamics in single wall carbon nanotube/poly(3-hexylthiophene) composites
(2008)Femtosecond transient absorption measurements on single wall carbon nanotube/poly(3-hexylthiophene) composites are used to investigate the relaxation dynamics of this blended material. The influence of the addition of ...

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 ...

Finite Difference Schemes for the Cauchy–Navier Equations of Elasticity with Variable Coefficients
(2015)We solve the variable coefficient Cauchy–Navier equations of elasticity in the unit square, for Dirichlet and Dirichlet-Neumann boundary conditions, using second order finite difference schemes. The resulting linear systems ...

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. ...

First measurement of the ratio B(t → Wb)/B(t → Wq) and associated limit on the Cabibbo-Kobayashi-Maskawa element ΙVtbΙ
(2001)The ratio of the branching fraction from particle collisions were measured. The data was recorded by the Collider Detector at fermilab during the Tevatron run. The measured values were in agreement with the standard model ...

First measurements of inclusive W and Z cross sections from run II of the fermilab tevatron collider
(2005)We report the first measurements of inclusive W and Z cross sections times leptonic branching ratios for pp collisions at √s = 1.96 TeV, based on their decays to electrons and muons. The data correspond to an integrated ...

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 ...

Improved detection of breast cancer nuclei using modular neural networks
(2000)A modular neural network-based approach to detect and classify breast cancer nuclei stained for steroid receptors in hispathological sections is evaluated. The system named biopsy analysis support system (BASS) is designed ...

Indirect adaptive control for systems with input rate saturation
(2008)An indirect adaptive control design with anti-windup augmentation for stable systems subject to input magnitude saturation is extended to address systems with significant input rate constraints. We use the method of ...

Information capacity of MIMO channels with relative entropy constraint
(2006)This paper addresses the issue of multiple-input multiple-output (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 ...
