REVISING THE SI: THE JOULE TO REPLACE THE KELVIN AS A BASE UNIT
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 2
Abstract
The joule is proposed to replace the kelvin in the set of SI base units. Arguments in favour of such replacement are presented, including improved standard accuracy and unit system coherence. The joule is also proposed to be added to the quantum metrological triangle (which couples the volt, the ampere and the hertz) to transform it into a system called quantum metrological pyramid, that would couple four units rather than three, and allow comparison of the respective standards.

FOUR-PARAMETER SINE-FITTING ALGORITHM FOR DETECTION AND CLASSIFICATION OF TRANSIENTS AND WAVEFORM DISTORTIONS
This paper describes a new method for detection of some power quality (PQ) disturbances, namely transients and waveform distortions. The proposed algorithm is based on a modified version of the four-parameter sine-fitti...
