    Library of software modules for detecting extreme events.
    Internal code: TN01000024/13-V02 ; 2022
    Technical parameters: K dosažení popsaných detekcí jsou použity pokročilé metody využívající konkrétní strukturu problému. Knihovna je navržena v programovacím jazyce Python. Má strukturu centrální části (TN01000024/13-)V2.1 s obecnými analytickými moduly, doplněné specializovaným modulem V2.2 pro analýzu dat z non-destructive testing (NDT), a specializovaným modulem V2.3 pro analýzu video dat.
    Economic parameters: Výsledkem je knihovna softwarových modulů schopných detekovat náhlé události a detekovat přechody mezi různými režimy studovaného systému. Klíčovou funkcionalitou je detekce zásadních změn v systému zvolené kritické infrastruktury. Tato schopnost umožňuje operátorům efektivně detekovat extrémní události a stavové přechody. LICENCE: Modul V2.1: GNU Affero General Public License v3.0. Modul V2.2: bez licence, avšak všechna práva vyhrazena. Modul V2.3: Modul pro analýzu videodat je dostupný účastníkům projektu v neveřejném repozitáři, ostatním zájemcům bude nabízen pod komerční licencí.
