About SYSEV

SYSEV is for "System evolution". It is also a play on words "sysev" being pronounced "six F" in French. The 6 "F's" could be : Faits (= facts), Fluage (= creep of materials), Fiabilité (= reliability), Fatigue (= fatigue of systems), Feedback and Fenetre (= window). This website is devoted to being a "glass-case" on the way physical and biological systems evolve and age following a general adaptation pattern. The use of ".com" is not because of a commercial goal but only to give it more visibility.

Two aspects are considered here :

INFORMATIVE :to provide scientific information on the developments.

STUDIES :to offer free consultancy on ageing or evolving systems.
