When a steel pilot plant reactor was emptied, and left exposed to the humid summer atmosphere over a weekend, a heavy corrosion deposit formed on the inner surface. Because the process stream contained triflic acid (trifluoromethanesulfonic acid, CF3SO3H), the engineer wanted to determine whether the deposit contained triflate(s) [1]. The brown deposit was ground in a mortar and pestle. The maj...

During investigations of phase transformation kinetics by diffraction techniques, several hundreds or even thousands of diffraction patterns are collected. Automation of the data analysis process is mandatory to perform for example a long sequence of Rietveld refinements. The Bragg edge transmission (BET) technique, a neutron time-of-flight method, allows acquiring patterns of sufficient statis...

The notion of algebraic immunity of Boolean functions has been generalized in several ways to vector-valued functions and/or over arbitrary finite fields and reasonable upper bounds for such generalized algebraic immunities has been proved in Armknecht and Krause (Proceedings of ICALP 2006, LNCS, vol. 4052, pp 180–191, 2006), Ars and Faugere (Algebraic immunity of functions over finite fields, ...
