Foundations of population-based SHM, Part III: Heterogeneous populations – Mapping and transfer

چکیده

This is the third and final paper in a series laying foundations for theory/methodology of Population-Based Structural Health Monitoring (PBSHM). PBSHM involves utilising knowledge from one set structures population applying it to different set, such that predictions about health states each member can be performed improved. Central ideas behind are those transfer mapping. In context PBSHM, using information source domain structure, where labels known given feature sets, mapping these onto unlabelled space different, target structure. means classifier trained on transformed data will generalise data; i.e. built structure another, making Heath (SHM) cost-effective applicable wide range challenging industrial scenarios. process features across domains defined here via adaptation, subcategory learning. A mathematical underpinning when adaptation possible structural dynamics provided, with reference topology within graphical representation structures. Subsequently, novel procedure performing topologically outlined.

Foundations of Heterogeneous Specification

We provide a semantic basis for heterogeneous specifications that not only involve different logics, but also different kinds of translations between these. We show that Grothendieck institutions based on spans of (co)morphisms can serve as a unifying framework providing a simple but powerful semantics for heterogeneous specification.
