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

Article
Coding techniques for faulttolerant 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 ...

Article
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 phaseshiftkeying modulation over a white noise ...

Demo: Indoor geolocation on multisensor smartphones
(2013)In this demo, we present an efficient hybrid indoor positioning solution that uses multisensory locationoriented observations, including WiFi, accelerometer, gyroscope and digital compass data, that are widely available ...

Determination of the number of errors in DFT codes subject to lowlevel quantization noise
(2008)This paper analyzes the effects of quantization or other lowlevel noise on the error correcting capability of a popular class of realnumber BoseChaudhuriHocquenghem (BCH) codes known as discrete Fourier transform (DFT) ...

Article
Error detection and correction in switched linear controllers via periodic and nonconcurrent 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 ...

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

Faulttolerant convolution via chinese remainder codes constructed from noncoprime moduli
(2008)This paper develops a framework for performing faulttolerant convolution via errorcorrecting codes based on the chinese remainder theorem (CRT) with noncoprime moduli. In contrast to convolution that is protected through ...

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 ...

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

Nonconcurrent error detection and correction in discretetime LTI dynamic systems
(2001)In this paper we develop faulttolerant constructions for discretetime (DT) linear timeinvariant (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 faulttolerant discretetime linear timeinvariant ...

Article
Nonconcurrent Error Detection and Correction in FaultTolerant Linear FiniteState Machines
(2003)In this paper, we construct faulttolerant linear finitestate machines (LFSMs) in which error detection and correction can be performed nonconcurrently (e.g., periodically). More specifically, by jointly choosing the state ...

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

Article
Softdecision decoding of linear block codes using preprocessing and diversification
(2007)Orderw reprocessing is a suboptimal softdecision decoding approach for binary linear block codes in which up to w bits are systematically flipped on the socalled most reliable (information) basis (MRB). This correspondence ...

Stable indirect adaptive control of continuoustime 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 ...
