Matrix-Valued Gegenbauer-Type polynomials
(Springer, 2017-12)
We introduce matrix-valued weight functions of arbitrary size, which are analogues of the weight function for the Gegenbauer or ultraspherical polynomials for the parameter ν> 0. The LDU-decomposition of the weight is ...
Constrained Linear Regularised State Estimator For Observability Analysis In Power Systems
(Inst Engineering Technology-IETHertford, 2016)
Acoustic Event Classification using spectral band selection and Non-Negative Matrix Factorization-based features
(Elsevier Ltd, 2016)
Feature extraction methods for sound events have been traditionally based on parametric representations specifically developed for speech signals, such as the well-known Mel Frequency Cepstrum Coefficients (MFCC). However, ...
Matrix effects in supercritical CO2 extraction of essential oils from plant material
(ELSEVIER SCI LTD, 2009)
In this work, we reviewed the effect of the solid matrix in the supercritical CO2 (SC-CO2) extraction of essentials oils from plant material. A diffusional model was adopted that assumed the substrate is as an homogeneous ...
NMF-Based Spectral Analysis for Acoustic Event Classification Tasks
(Scopus, 2013)
In this paper, we propose a new front-end for Acoustic Event Classification tasks (AEC). First, we study the spectral contents of different acoustic events by applying Non-Negative Matrix Factorization (NMF) on their ...
NMF-based temporal feature integration for acoustic event classification
(International Speech and Communication Association, 2013)
In this paper, we propose a new front-end for Acoustic Event Classification tasks (AEC) based on the combination of the temporal feature integration technique called Filter Bank Coefficients (FC) and Non-Negative Matrix ...

Bird sound spectrogram decomposition through Non-Negative Matrix Factorization for the acoustic classification of bird species
(Public Library of Science, 2017)
Feature extraction for Acoustic Bird Species Classification (ABSC) tasks has traditionally been based on parametric representations that were specifically developed for speech signals, such as Mel Frequency Cepstral ...
Oxygen diffusion in soils: Understanding the factors and processes needed for modeling
(Inst Investigaciones Agropecuarias, 2015)
Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...
