Stator Current Analysis by Subspace Methods for Fault Detection in Induction Machines [PDF]
, 2015 International audienceThis paper aims to develop a condition monitoring architecture for induction machines, with focus on bearing faults. The main objective of this paper is to identify fault signatures at an early stage by using high-resolution ...

Effect of random antenna element displacements on sparse-UCA-Root-MUSIC direction-of-arrival estimation [PDF]
, 2018 We leverage a generalized polynomial chaos (GPoC) expansion to model the effect of correlated random antenna element displacements in a uniform circular antenna array (UCA) on the probability density function of the estimated directions-of-arrival (DOAs).

Grid-free compressive beamforming [PDF]
, 2015 The direction-of-arrival (DOA) estimation problem involves the localization of a few sources from a limited number of observations on an array of sensors, thus it can be formulated as a sparse signal reconstruction problem and solved efficiently with ...

Nondestructive testing of optical fibers using the optical coherence tomography
St. Petersburg Polytechnical University Journal: Physics and MathematicsOptical coherence tomography (OCT) is a widely used imaging technique in biomedical research and non-destructive testing. It provides high spatial resolution, but for some applications, such as non-destructive testing, a further improvement in resolution

Partial Relaxation Approach: An Eigenvalue-Based DOA Estimator Framework
, 2018 In this paper, the partial relaxation approach is introduced and applied to DOA estimation using spectral search. Unlike existing methods like Capon or MUSIC which can be considered as single source approximations of multi-source estimation criteria, the

A Root-MUSIC-Like Direction Finding Method for Cyclostationary Signals [PDF]
EURASIP Journal on Advances in Signal Processing, 2004 Summary: We propose a new root-MUSIC-like direction finding algorithm that exploits cyclostationarity in order to improve the direction-of-arrival estimation. The proposed cyclic method is signal selective, it allows to increase the resolution power and the noise robustness significantly, and it is also able to handle more sources than the number of ...

Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
