Um estudo sobre Proper Orthogonal Decomposition: fundamentação teórica
(Universidade Federal de São Paulo (UNIFESP), 2020-07-28)
The main objective of this work is to study the mathematical foundations of the Proper Orthogonal Decomposition (POD) method, the essence of which is to provides an orthogonal basis for representing a given set of data in ...
Proper orthogonal decomposition for model reduction of a vibroimpact system
(Springer, 2012-09)
The application that inspires this work is the percussion drilling. This problem has impacts and presents uncertainties. In this first analysis the focus is on the constru ction of an efficient reduced-order model to deal ...
Model updating of the non-linear vibrating structures through Volterra series and proper orthogonal decomposition
(Katholieke Univ Leuven, Dept Werktuigkunde, 2012-01-01)
Classical procedures for model updating in non-linear mechanical systems based on vibration data can fail because the common linear metrics are not sensitive for non-linear behavior caused by gaps, backlash, bolts, joints, ...

Approximation by partial isometries and symmetric approximation of finite frames
(Birkhauser Boston Inc, 2018-08)
We solve the problem of best approximation by partial isometries of given rank to an arbitrary rectangular matrix, when the distance is measured in any unitarily invariant norm. In the case where the norm is strictly convex, ...
