Extrapolation of AR models using cubic splines for damage progression evaluation in composite structures
(2021-02-01)
This paper presents the potentiality of the use of extrapolation of a set of Auto-Regressive (AR) models to inspect a future damage sensitive indices based on changes in one-step-ahead prediction errors. The key idea is ...
Autoregressive model extrapolation using cubic splines for damage progression analysis
(2021-01-01)
The application of Structural Health Monitoring (SHM) methods focuses mainly on its initial levels of the hierarchy of damage identification. The contribution of this paper is to propose a new strategy that allows going ...
Data-driven autoregressive model identification for structural health monitoring in anisotropic composite plates
(2019-01-01)
A simple data-driven AutoRegressive (AR) model may be used to assess a model to describe and to predict the time-series outputs of the PZT sensors receiving Lamb waves for different operating conditions in composite ...
Extrapolation of autoregressive model for damage progression analysis
(Universidade Estadual Paulista (Unesp), 2019-04-16)
O principal objetivo deste trabalho é usar métodos de extrapolação em coeficientes de modelos autorregressivos (AR), para fornecer informações futuras de condições de estruturas na existência de mecanismo de danos ...
Extrapolation of a structural equation model for digital soil mapping
(Elsevier, 2020-05)
In theory, two separate regions with the same soil-forming factors should develop similar soil conditions. This theoretical finding has been used in digital soil mapping (DSM) to extrapolate a model from one area to another, ...
Using scale heights derived from bottomside ionograms for modelling the IRI topside profile
(Copernicus Publications, 2005-05)
Groundbased ionograms measure the Chapman scale height HT at the F2-layer peak that is used to construct the topside profile. After a brief review of the topside model extrapolation technique, comparisons are presented ...
From town to town: Predicting the taxonomic, functional and phylogenetic diversity of birds using NDVI
(Elsevier Science, 2020-12)
Biodiversity mapping in urban areas is imperative for their conservation. Remote sensors produce environmental information, such as the Normalized Difference Vegetation Index (NDVI), an indicator of vegetation cover in ...
Trends in Technological Advances in Food Dehydration, Identifying the Potential Extrapolated to Cocoa Drying: A Bibliometric Study
This work presents a systematic review of the literature based on bibliometric networks structured with the VOSviewer application, which was run on different scientific databases, seeking for improvements of drying processes ...
Magnetic Topology of Active Regions and Coronal Holes: Implications for Coronal Outflows and the Solar Wind
(Springer, 2012-11)
During 2-18 January 2008 a pair of low-latitude opposite-polarity coronal holes (CHs) were observed on the Sun with two active regions (ARs) and the heliospheric plasma sheet located between them. We use the Hinode/EUV ...
How Can Active Region Plasma Escape into the Solar Wind from Below a Closed Helmet Streamer?
(Springer, 2014-11)
Recent studies show that active-region (AR) upflowing plasma, ob- served by the EUV-Imaging Spectrometer (EIS), onboard Hinode, can gain access to open field-lines and be released into the solar wind (SW) via magnetic- ...
