Separable codes for detecting unidirectional errors

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1989
Systematic and separable codes are widely used for error detection in VLSI circuits. Recently, systematic codes have been found for detecting t-unidirectional and burst unidirectional errors. In such codes, r checkbits are added to k information bits to form a codeword of length (k+r), and it is assumed that all 2/sup k/ possible information k-tuples ...

Separability of ternary Error-Correcting Output Codes

2008 19th International Conference on Pattern Recognition, 2008
Error correcting output codes (ECOC) represent a successful framework to deal with multi-class categorization problems based on combining binary classifiers. In this paper, we present a new formulation of the ternary ECOC distance and the error-correcting capabilities in the ternary ECOC framework.

Parity-Check Matrices Separating Erasures From Errors

IEEE Transactions on Information Theory, 2013
Most decoding algorithms of linear codes, in general, are designed to correct or detect errors. However, many channels cause erasures in addition to errors. In principle, decoding over such channels can be accomplished by deleting the erased symbols and decoding the resulting vector with respect to a punctured code.

Four-point error separation technique for cylindricity

Measurement Science and Technology, 2018
A four-point error separation technique integrating three-point roundness and two-point straightness error separations is proposed to measure and reconstruct a cylindrical profile for the accurate evaluation of cylindricity. Four probes mounted onto two sections in the probe carriage target the surface of the cylinder to detect the differential vector ...

Method of optical interference testing error separation

Frontiers of Optoelectronics in China, 2010
During the testing of aspherical mirrors through the null compensation method, structural parameters observe changes which affect the test results of interference pattern. Several errors are induced due to the maladjustment among compensator, interferometer and the mirror under test.

Research of Spindle Error Separation Mixed Method

Advanced Materials Research, 2013
This paper introduces a spindle error separation technique called orthogonal mixed method. The problem of harmonic suppression is solved by the orthogonal mixed method, which exists in the process of measurement based on three point method.The measuring system consisting of a displacement sensor and a angle sensor is developed for spindle error and ...

Two ADPCM Algorithms with Widely Separated Error Recovery Times

IEEE Transactions on Communications, 1979
Two adaptive differential pulse code modulation (ADPCM) algorithms are discussed that provide for transmitter-receiver resynchronization when used in a non-zero error rate digital transmission medium. Novel techniques are used in the algorithms (e.g., step-size bias) and in their extensive characterization (e.g., intermodulation distortion measurements)

On separability for deformations and gross errors

Journal of Geodesy, 1990
According to the testing theory with two alternative hypotheses, the theory of detectability for a deformation monitoring network has been extended to the theory of separability for deformations and gross errors. With this theory it can be evaluated whether deformations and gross errors can be statistically distinguished each other, which is very ...
