Time-frequency representation of earthquake accelerograms and inelastic structural response records using the adaptive chirplet decomposition and empirical mode decomposition [PDF]

open access: yes, 2007
In this paper, the adaptive chirplet decomposition combined with the Wigner-Ville transform and the empirical mode decomposition combined with the Hilbert transform are employed to process various non-stationary signals (strong ground motions and ...

The effect of technological changes on energy consumption in Iran: a structural decomposition analysis

open access: yesInternational Journal of Sustainable Energy, 2022
This study proposed a simple method to evaluate the effect of technological changes in sectors on energy consumption changes. Technological changes decomposed into two factors.

3-D axisymmetric subsonic flows with nonzero swirl for the compressible Euler-Poisson system [PDF]

open access: yes, 2016
We address the structural stability of 3-D axisymmetric subsonic flows with nonzero swirl for the steady compressible Euler-Poisson system in a cylinder supplemented with non small boundary data. A special Helmholtz decomposition of the velocity field is

Drivers of global nitrogen emissions

open access: yesEnvironmental Research Letters, 2022
Nitrogen is crucial for sustaining life. However, excessive reactive nitrogen (Nr) in the form of ammonia, nitrates, nitrogen oxides or nitrous oxides affects the quality of water, air and soil, resulting in human health risks.

Revealing the changes in water footprint at the provincial level and their drivers in the Yellow River Basin, China

open access: yesEnvironmental Research Communications, 2023
Water scarcity has become the most significant limiting factor for sustainable economic and social development in the Yellow River Basin (YRB). Despite this, most current studies on water resources in the YRB from a water footprint (WF) perspective have ...

Decomposition analysis of economic growth in Afar region, Ethiopia

open access: yesCogent Economics & Finance, 2022
This paper is aimed to decompose, the economic growth of the Afar national regional state of Ethiopia in to labor productivity, employment rate and working age population and to verify whether the positive economic growth registered earlier on the region

Structural decomposition analysis with disaggregate factors within the Leontief inverse

open access: yesJournal of Economic Structures, 2021
A trivial case in input–output structural decomposition analysis is a decomposition of a product of variables, or factors, where one factor is an inverse—typically, Leontief inverse—of a sum of other factors.

Sectoral water footprint dynamics: An input-output structural decomposition analysis for Morocco [PDF]

open access: yesE3S Web of Conferences, 2021
Over the last decades, Morocco has been facing increasingly severe water scarcity. To quantify water use in Morocco, we refer to the water footprint (WF) concept, including both direct and indirect water use. WF considered covers internal WF and exported

Identifying the sources of energy use change: Multiple calibration decomposition analysis and structural decomposition analysis [PDF]

open access: yesStructural Change and Economic Dynamics, 2011
Abstract Decomposition methodologies are requisite to identify the sources of changes in energy use or carbon dioxide emissions. This paper is an inquiry into the theoretical properties of such decomposition methodologies. The study first presents our new decomposition methodology – the Multiple Calibration Decomposition Analysis (MCDA) – as a tool ...

Material implication of Chile’s economic growth: combining material flow accounting (MFA) and structural decomposition analysis [PDF]

open access: yes, 2007
Over the last three decades, the economic integration of the Chilean economy into global markets has been taking place at a rapid pace. For example, in 1986, exports represented 29% of GDP while in 1996 they had increased to 38% of GDP.
