Structural analysis by partial decomposition

Journal of the Franklin Institute, 1970
Abstract A partial decomposition of the flexibility matrix of a structural system is shown to yield directly all the required information in the analysis from which displacements at the coordinates, internal forces and deformations can be obtained.

Regression component decomposition in structural analysis

Communications in Statistics - Theory and Methods, 1991
A crucial problem in the Lisrel model remains that of finding necessary and sufficient conditions for the identification of the parameters. But even if the parameters in a particular model are identifiable, there remains an indeterminacy of the scores of the latent variables.

Decomposition methods for structural reliability analysis

Probabilistic Engineering Mechanics, 2005
A new class of computational methods, referred to as decomposition methods, has been developed for predicting failure probability of structural and mechanical systems subject to random loads, material properties, and geometry. The methods involve a novel function decomposition that facilitates univariate and bivariate approximations of a general ...

Domain decomposition in acoustic and structure–acoustic analysis

Computer Methods in Applied Mechanics and Engineering, 2001
Conclusion: This paper suggests a scheme for modal decomposition of interacting structure-fluid and fluid-fluid systems. A symmetric standard eigenvalue analysis is employed for interacting systems based on eigenvalue analysis conducted on subdomains.

Structure-Preserving Sparse Decomposition for Facial Expression Analysis

IEEE Transactions on Image Processing, 2014
Although facial expressions can be decomposed in terms of action units (AUs) as suggested by the facial action coding system, there have been only a few attempts that recognize expression using AUs and their composition rules. In this paper, we propose a dictionary-based approach for facial expression analysis by decomposing expressions in terms of AUs.

Factor decomposition of China’s industrial electricity consumption using structural decomposition analysis

Structural Change and Economic Dynamics, 2019
Abstract We analyzed changes in China’s industrial electricity consumption using a structural decomposition model based on input-output analysis. China’s industrial electricity consumption changes during 2007–2012 were decomposed into four factors: electricity intensity, technology-input structural, final demand structure and total final demand.

Structural Analysis and Decomposition of Complex Systems

IFAC Proceedings Volumes, 1983
Abstract This paper deals with the application of hierarchical structural analysis to the decomposition and control of complex systems. The strength of the relationship between subsets of variables describing the systems is obtained by computation, using information theory concepts, among a set of experimental data. “Good decompositions” are obtained

Accounting for nitrogen in Denmark—a structural decomposition analysis

Ecological Economics, 1999
Abstract This paper examines the environmental-economic cycle for nitrogen in Denmark based on nitrogen input and output from different economic sectors. An input-output model is employed together with a nitrogen mass balance to apportion total nitrogen loading by final demand and estimate export and import of nitrogen from foreign trade. The changes

Using Additional Information in Structural Decomposition Analysis: The Path-based Approach

Economic Systems Research, 2008
Structural decomposition analysis (SDA) is a well-known methodology to assess the relative importance of effects that together constitute the actual change in a variable of interest. A widely recognized problem of SDA is that the results often depend strongly on the specific decomposition formula chosen, while numerous formulae are equivalent from a ...

Input-output structural decomposition analysis for Austria

Journal of Policy Modeling, 1989
Abstract The structural transformation of an economy, as represented, for example, by changes in the level and composition of net output value and of employment, raises questions about the sources of the shifts in the position of individual industries. Input-output structural decomposition analysis can ascribe the source of these shifts to changes in
