Unitary operators with decomposable corners
(Banach Mathematical Research Group, 2021-01)
We study pairs (U, L) , where U is a unitary operator in H and L⊂ H is a closed subspace, such that PL0U|L0:L0→L0has a singular value decomposition. Abstract characterizations of this condition are given, as well as relations ...
The singular value decomposition of a uniform matrixValores singulares de matrizes uniformes

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, ...
Monitoring of condition of the railway system.
(Association for Engineering Mechanics, 2010-05-31)
The multidimensional monitoring of symptoms applied to railway systems allow to detect and locate the sections of the track (straight and curved) that generate thedecrement of the safety and comfort of the passengers. It ...

Automatic online spike sorting with singular value decomposition and fuzzy C-mean clustering
(BioMed Central, 2012-08)
Background: Understanding how neurons contribute to perception, motor functions and cognition requires the reliable detection of spiking activity of individual neurons during a number of different experimental conditions. ...
Uncovering protein interaction in abstracts and text using a novel linear model and word proximity networks
(BioMed Central, 2008-09-01)
Background: We participated in three of the protein-protein interaction subtasks of the Second BioCreative Challenge: classification of abstracts relevant for protein-protein interaction (interaction article subtask [IAS]), ...
State of mechanical condition applied to industrial machines based on SVD method
(Universidad de Tarapaca, 2018-01-01)
A problem related to the operation of industrial machines has been the identification of the mechanical condition in exploitation, via dynamic performance variables which affect the nominal behavior of machine tasks. This ...
Quantification of Collagen Fiber Orientation and Organization by Singular Value Decomposition
(Sociedad Argentina de Bioingeniería, 2018-09)
Second-harmonic generation microscopy is a new imaging tool that allows analyzing non-centrosymmetric structures, such as collagen. This method can be used to detect structural organization of human ovarian extracellular ...
