French term or phrase: sous-échantillonnage glissant
Le sous-échantillonnage séquentiel consiste à découper le domaine de température I_T de la base de données en N sous-intervalles consécutifs disjoints (I_i )_(i=1,…,n) avec la même amplitude thermique ΔT.
Le **sous-échantillonnage glissant** consiste à découper le domaine de température I_T de la base de données en N sous-intervalles consécutifs ΔT. Il est alors question de construire un premier intervalle de température I_1 qui démarre avec la température la plus basse T_1 du domaine de température jusqu’à la température T_1+ΔT et le sous-intervalle suivant I_2 est obtenu en faisant glisser le sous-intervalle I_1 d’un décalage dT. Ainsi, I_2=[T_1+dT,T_1+dT+ΔT]. Cette opération est répétée jusqu’à ce que le sous-intervalle I_n atteint la température maximum de I_T.

"Sous-échantillonnage séquentiel" translates as sequential sub-sampling, but I can't find any similar literal translation of "sous-échantillonnage glissant" ("sliding sub-sampling"). I considered "progressive sub-sampling", but that also appears to correspond to "sous-échantillonnage séquentiel".

English translation:sub-sampling with lag
Explanation:
I'd translate what is happening literally. Sequential-subsampling is still being done but with a lag dt applied at each step.

OK - Claude-Andrew's version of the link will open for me (Tony's doesn't for some reason). It says "sub-sampling with sliding windows" - that's not canonical and the English seems a bit ropy e.g. "disjoined", but it's certainly a reasonable description of what's happening. Overlapping windows are created by shifting each by the lag dT.

They use "sliding sub-sampling" as a figure heading but I wouldn't use it on first occurrence - I'd go with "sub-sampling with sliding windows", "sub-sampling with lagged windows" or just "sub-sampling with lag".

This has a lot of extraneous stuff, but Sampling Time-Based Sliding Windows is a way of describing it
