An Introduction to Classical Inverse Eigenvalue Problems,Aim of these notes is to present an elementary introduction to classical inverse eigenvalue problems in one dimension. Attention is mainly focused on Sturm-Liouville differential operators given in canonical form on a finite interval. A uniqueness result for a fourth order Euler-Bernoulli operator is also discussed.清澈 发表于 2025-3-24 10:49:58

Entwicklungsstufen der Wasserkraftnutzung,odal parameters is discussed through three experimental cases of masonry structures: a civil building, a monumental structure and a nineteenth century railway bridge. Modal parameters are response quantities that are sensitive to damage, whose variation with respect to an undamaged state can be expl
