Harmonic Analysis of Multipath Index Time Series in GPS Stations†
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2015)
The identification of the cyclical and seasonal variations can be very important in time series. In this paper, the aim is to identify the presence of cyclical or seasonal variations in the indices of the multipath effect ...
The impact of OFDI on economic growth countries: an econometric approach using panel data and time-series evidence
(2012-12-20)
The thesis at hand adds to the existing literature by investigating the relationship between economic growth and outward foreign direct investments (OFDI) on a set of 16 emerging countries. Two different econometric ...
Aplicação e performance da análise de intervenção em séries de emissão de gases poluentes na Cidade do México
(Universidade Federal de Santa MariaBREngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de Produção, 2016-02-23)
This research aims to evaluate the performance of time-series models together with the use of analysis, when the time for action is determined by visual inspection of the series or the spectral analysis, greenhouse gas ...
SHAPE-BASED TIME SERIES ANALYSIS FOR REMOTE PHENOLOGY STUDIES
(Ieee, 2013-01-01)
Remote phenology has motivated the development of new technologies for pattern observation. In this scenario, digital cameras have been used as data source for studies that estimate changes on phenological events. In this ...
Using missing ordinal patterns to detect nonlinearity in time series data
(American Physical Society, 2017-08)
The number of missing ordinal patterns (NMP) is the number of ordinal patterns that do not appear in a series after it has been symbolized using the Bandt and Pompe methodology. In this paper, the NMP is demonstrated as a ...
Time series characterization via horizontal visibility graph and Information Theory
(Elsevier Science, 2016-12)
Complex networks theory have gained wider applicability since methods for transformation of time series to networks were proposed and successfully tested. In the last few years, horizontal visibility graph has become a ...
Using Time Series Analysis to support the Water Resources Management in the Upper Basin of the Suquía River
(Universidad de Effurun, 2015-03)
A time series analysis is a valuable tool to get information about analyzed data structures and their components, which providesa good basis for successful future predictions. This information is useful to make decisions ...
