A Systematic (12, 8) Code for Correcting Single Errors and Detecting Adjacent Errors
Schwartz and Wolf give a parity check matrix for a systematic (12,8) binary code that corrects all single errors and detects eight of the nine double adjacent errors within any of the three 4-bit nibbles. Here, we present a parity check matrix for a systematic (12,8) binary code that corrects all single errors and detects any pair of errors within a nibble. nibble, parity-check matrix, systemat...
متن کاملDiagnosing and Correcting Systematic Errors in Spectral-Based Digital Imaging
A digital imaging system containing a calibration target, an image capture device, and a mathematical model to estimate spectral reflectance factor was treated as a spectrophotometer and as such subject to systematic and random errors. The systematic errors considered were photometric zero, photometric linear and nonlinear scale, wavelength linear and nonlinear scale, and bandwidth. To diagnose...
متن کاملGAIA Spectroscopy and Radial Velocities
GAIA spectroscopic and radial velocity performancies are reviewed on the base of groundbased test observations and simulations. The prospects for accurate analysis of stellar atmospheres (temperature, gravity, chemical abundances, rotation, peculiarities) and precise radial velocities (single stars, binaries, pulsating stars) are colorful provided the spectral dispersion is high enough. A highe...
متن کاملCorrecting Dependency Annotation Errors
Building on work detecting errors in dependency annotation, we set out to correct local dependency errors. To do this, we outline the properties of annotation errors that make the task challenging and their existence problematic for learning. For the task, we define a feature-based model that explicitly accounts for non-relations between words, and then use ambiguities from one model to constra...
متن کاملCorrecting Grammatical Verb Errors
Verb errors are some of the most common mistakes made by non-native writers of English but some of the least studied. The reason is that dealing with verb errors requires a new paradigm; essentially all research done on correcting grammatical errors assumes a closed set of triggers – e.g., correcting the use of prepositions or articles – but identifying mistakes in verbs necessitates identifyin...
