The melting point of gallium (29.7646 °C) is a defining thermometric fixed point of the International Temperature Scale of 1990 (ITS-90). Realization of this melting point is performed using a fixedpoint cell containing high-purity (≥99.999 99 wt. % pure) gallium. A 30 kg single lot of gallium (99.999 9956 wt. % pure) constituting Standard Reference Material (SRM) 1751 was evaluated, and certif...

In this report we give an overview of our first evaluations of the upcoming H.26L video encoding standard of the ITU–T. Since this standard is still in the development phase, all of the results presented here are to be seen as preliminary, as is the introduction to the standard itself. The video encodings analyzed in this report have been generated with a preliminary version of the H.26L encode...

Parallel addition in integer base is used for speeding up multiplication and division algorithms. k-block parallel addition has been introduced by Kornerup in [14]: instead of manipulating single digits, one works with blocks of fixed length k. The aim of this paper is to investigate how such notion influences the relationship between the base and the cardinality of the alphabet allowing block ...
