A Hybrid Parameterization Technique for Speaker Identification [PDF]

open access: yes, 2008
Classical parameterization techniques for Speaker Identification use the codification of the power spectral density of raw speech, not discriminating between articulatory features produced by vocal tract dynamics (acoustic-phonetics) from glottal source ...

Survey of effectiveness of inverse analysis computation [PDF]

open access: yesComputer Methods in Materials Science, 2014
The paper presents a survey of inverse analysis focusing on two aspects: computing time and accuracy of the solution. Identification of flow stress model in metal forming processes was considered as the inverse problem.

Approximation of Bayesian inverse problems for PDEs [PDF]

open access: yes, 2010
Inverse problems are often ill posed, with solutions that depend sensitively on data. In any numerical approach to the solution of such problems, regularization of some form is needed to counteract the resulting instability.

Two inverse non-stationary problems of axially symmetric deformation of a finite-length elastic cylindrical shell [PDF]

open access: yesAvtomobilʹnyj Transport (Harʹkov), 2022
Problem. Among the many problems of the solid mechanics, there is a whole class of problems that are related to inverse problems. In turn, among the inverse problems, many problems are ill-posed.

Identification of Phase Inversion on Sieve Trays [PDF]

open access: yesChemie Ingenieur Technik, 2021
AbstractThe fundamental differences in hydrodynamics of the froth and spray regime account for the ongoing interest in search for the point of phase inversion. This short communication presents a new approach for identification of phase inversion on sieve trays in terms of an image‐based measurement technique.

Inverse medium problem for a singular contrast [PDF]

open access: yes, 2019
We consider an inverse medium problem in two- and three-dimensional cases. Namely, we investigate the problem of reconstruction of unknown compactly supported refractive index (contrast) from L-2 with a fixed positive wave number.

Adaptive inverse control using kernel identification [PDF]

open access: yes2012 American Control Conference (ACC), 2012
Kernel methods are exploited to implement an adaptive inverse control scheme of which a first introductory presentation is given. The resulting controller has faster convergence than the solutions proposed in literature utilizing Support Vector Machines (SVMs) [1] and Artificial Neural Networks (ANNs) [2].

Model predictive control architecture for rotorcraft inverse simulation [PDF]

open access: yes, 2013
A novel inverse simulation scheme is proposed for applications to rotorcraft dynamic models. The algorithm adopts an architecture that closely resembles that of a model predictive control scheme, where the controlled plant is represented by a high-order ...
