Coding approaches to fault tolerance in linear dynamic systems
(2005)This paper discusses fault tolerance in discrete-time dynamic systems, such as finite-state controllers or computer simulations, with focus on the use of coding techniques to efficiently provide fault tolerance to linear ...

Coding techniques for fault-tolerant parallel prefix computations in Abelian groups
(2004)This paper presents coding techniques that can be used to provide fault tolerance to a parallel prefix computation that is performed on a binary tree of processing nodes. More specifically, we discuss how a parallel prefix ...

Decoding algorithm and architecture for BCH codes under the Lee metric
(2008)The Lee metric measures the circular distance between two elements in a cyclic group and is particularly appropriate as a measure of distance for data transmission under phase-shift-keying modulation over a white noise ...

Determination of the number of errors in DFT codes subject to low-level quantization noise
(2008)This paper analyzes the effects of quantization or other low-level noise on the error correcting capability of a popular class of real-number Bose-Chaudhuri-Hocquenghem (BCH) codes known as discrete Fourier transform (DFT) ...

Error detection and correction in switched linear controllers via periodic and non-concurrent checks
(2006)Control systems that utilize switched linear controllers have proven to be useful (and, in some cases, essential) for accomplishing certain control objectives in particular classes of plants. These controllers are often ...

Fault-tolerant computation in groups and semigroups: Applications to automata, dynamic systems and Petri nets
(2002)The traditional approach to fault-tolerant computation has been via modular hardware redundancy. Although universal and simple, modular redundancy is inherently expensive and inefficient. By exploiting particular structural ...

Fault-tolerant convolution via chinese remainder codes constructed from non-coprime moduli
(2008)This paper develops a framework for performing fault-tolerant convolution via error-correcting codes based on the chinese remainder theorem (CRT) with non-coprime moduli. In contrast to convolution that is protected through ...

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 ...

Finite-state machine embeddings for nonconcurrent error detection and identification
(2005)In digital sequential systems that operate over several time steps, a state-transition fault at any time step during the operation of the system can corrupt its state and render its future functionality useless. Such ...

Non-concurrent error detection and correction in discrete-time LTI dynamic systems
(2001)In this paper we develop fault-tolerant constructions for discrete-time (DT) linear time-invariant (LTI) dynamic systems that are build out of appropriately interconnected delay, adder and gain elements. More specifically, ...

Nonconcurrent error correction in the presence of roundoff noise
(2009)This paper analyzes the effects of roundoff noise on our ability to nonconcurrently detect and identify transient faults that corrupt state variables during the operation of a fault-tolerant discrete-time linear time-invariant ...

Nonconcurrent Error Detection and Correction in Fault-Tolerant Linear Finite-State Machines
(2003)In this paper, we construct fault-tolerant linear finite-state machines (LFSMs) in which error detection and correction can be performed nonconcurrently (e.g., periodically). More specifically, by jointly choosing the state ...

A p-version MITC finite element method for Reissner-Mindlin plates with curved boundaries
(2006)We consider the approximation of Reissner-Mindlin plates with curved boundaries, using a p-version MITC finite element method. We describe in detail the formulation and implementation of the method, and emphasize the need ...

Soft-decision decoding of linear block codes using preprocessing and diversification
(2007)Order-w reprocessing is a suboptimal soft-decision decoding approach for binary linear block codes in which up to w bits are systematically flipped on the so-called most reliable (information) basis (MRB). This correspondence ...

Stable indirect adaptive control of continuous-time systems with no a priori knowledge on the parameters
(Publ by Pergamon Press Inc, 1993)A crucial drawback of indirect adaptive control is the stabilizability or controllability of the estimated plant model which is required in order to calculate the controller parameters. Loss of stabilizability at a particular ...
