Structured pseudospectra in structural engineering [PDF]

open access: yes, 2005
This paper presents a new method for computing the pseudospectra of a matrix that respects a prescribed sparsity structure. The pseudospectrum is defined as the set of points in the complex plane to which an eigenvalue of the matrix can be shifted by a ...

Socioeconomic status, parenting factors and academic achievement among Chinese adolescents aged 12–13: How do they relate?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Extensive research has shown that students from higher socioeconomic status (SES) backgrounds generally outperform their lower SES peers. Nevertheless, some low SES students succeed, albeit it ‘against the odds.’ Coleman's (1988) theory of social capital in the family suggests that financial capital, human capital and social capital all affect

The Solutions to Matrix Equation AX=B with Some Constraints

open access: yesJournal of Applied Mathematics, 2014
Let P be a given Hermitian matrix satisfying P2=I. Using the eigenvalue decomposition of P, we consider the least squares solutions to the matrix equation AX=B with the constraints PX=XP and X*=X.

Extremal Inverse Eigenvalue Problem for a Special Kind of Matrices

open access: yesJournal of Applied Mathematics, 2014
We consider the following inverse eigenvalue problem: to construct a special kind of matrix (real symmetric doubly arrow matrix) from the minimal and maximal eigenvalues of all its leading principal submatrices. The necessary and sufficient condition for

Sustainable Innovation and Impact on Triple Bottom Line Performance: Are Innovation Types Simple Mediators?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the way sustainable innovation, conceptualized as a second‐order construct integrating sustainable orientation and innovation culture, impacts triple bottom line (TBL) performance. It also examines the mediating roles of product, process, organizational, and marketing innovations.

Matrix Iteration for Large Symmetric Eigenvalue Problems [PDF]

open access: yes, 2002
Eigenvalue problems are common in engineering tasks. In particular the prediction of structural stability and dynamic behavior leads to large symmetric real matrices with profile structure, for which a set of successive eigenvalues and the ...
