Algebraic approaches for fault identification in discreteevent systems
(2005)In this note, we develop algebraic approaches for fault identification in discreteevent systems that are described by Petri nets. We consider faults in both Petri net transitions and places, and assume that system events ...

Categorized sliding window in streaming data management systems
(2008)For many applications, data is collected at very large rates from various sources. Applications that produce results from this data have a requirement for very efficient processing in order to achieve timely decisions. An ...

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 ...

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 ...

Geneticsbased machine learning for the assessment of certain neuromuscular disorders
(1996)Clinical electromyography (EMG) provides useful information for the diagnosis of neuromuscular disorders. The utility of artificial neural networks (ANN's) in classifying EMG data trained with backpropagation or Kohonen's ...

Graphical inference methods for fault diagnosis based on information from unreliable sensors
(2006)In this paper, we study the application of decoding algorithms to the multiple fault diagnosis (MFD) problem. Prompted by the resemblance between graphical representations for MFD problems and parity check codes, we develop ...

LDPC decoding on the Intel SCC
(2012)LowDensity ParityCheck (LDPC) codes are powerful error correcting codes used today in communication standards such as DVBS2 and WiMAX to transmit data inside noisy channels with high error probability. LDPC decoding is ...

On the channel capacity of wireless fading channels
(2002)The objectives of this paper are twofold. First, to point out the significance of certain results on stochastic processes in computing the channel capacity for flat fading wireless channels. Second, to design an optimal ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2003)The sampling rate in most hard disk drives (HDDs) is limited by the number of servo burst sectors that have prewritten position error signal (PES) data and by the spinning speed of the HDD. This paper presents an algorithm ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2002)Track density in hard disk drives (HDD) is related to the performance characteristics of the HDD servo control system. Higher track density can be achieved by improving the performance characteristics of the servo controller ...

Rate distortion function with causal decoding
(2010)This paper considers source coding of general sources with memory, when causal feedback is available at the decoder. The rate distortion function is defined as the infimum of the socalled directed information over causal ...

Robust coding for uncertain sources: A minimax approach
(2005)This paper is concerned with designing minimum average length uniquely decodable codes, for a family of source distributions for which the relative entropy with respect to a given nominal distribution is bounded above by ...
