Efficient Characterization of Stochastic Electromagnetic Fields using Eigenvalue Decomposition and Principal Component Analysis Method

open access: yes, 2014
Stochastic electromagnetic fields can be described by the correlation function of the field amplitudes in all pairs of space points. We show that the description of stochastic electromagnetic fields by correlation matrices can be simplified using the ...

Supply Chain Network, ESG Scores and Financial Performance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper provides novel evidence on the role of supply chain networks in influencing firms' environmental, social and governance (ESG) scores and financial performance. Our analysis employs financial, board, ESG and supply chain data, resulting in an unbalanced panel of over 16,000 firm‐year observations from 3028 publicly traded US firms ...

Domain decomposition methods for eigenvalue problems [PDF]

open access: yes, 2000
This paper proposes several domain decomposition methods to compute the smallest eigenvalue of linear self-adjoint partial differential operators. Let us be given a partial differential operator on a domain which consists of two nonoverlapping subdomains.

Signal Eigenvalue Factor for Synthetic Transmit Aperture Ultrasound Imaging

open access: yesIEEE Access, 2018
Synthetic transmit aperture (STA) ultrasound imaging that obtain bi-directional focusing can create a high-resolution image. Delay-and-sum (DAS) approach is performed in both transmit and receive modes, which leads to low contrast and high sidelobe ...

Successive eigenvalue relaxation: a new method for the generalized eigenvalue problem and convergence estimates [PDF]

open access: yes, 2001
We present a new subspace iteration method for the efficient computation of several smallest eigenvalues of the generalized eigenvalue problem Au = lambda Bu for symmetric positive definite operators A and B.

Smart Cities Leading the Green Transition: Linking Open Innovation and Entrepreneurial Dynamics

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Smart cities today are vibrant spaces where technology, collaboration, and sustainability come together to shape a better future. The green transition in cities is not just about building greener infrastructure or cutting emissions. It also changes how people, institutions, and businesses think and act.

Corporate Governance and Environmental Performance: Does Contingency Theory Affect the Explanatory Power of Theoretical Frameworks?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT There is extensive literature on the relationship between corporate governance (CG) and firms' environmental performance (EP). However, the empirical findings remain somewhat equivocal. A variety of theoretical approaches have been utilised to provide a suitable basis for explaining the causal relationship, including legitimacy theory ...

Computation of H-infinity norm of linear discrete-time periodic systems [PDF]

open access: yes, 2006
We propose an efficient an numerically reliable procedure for the computation of H-infinity norm of discrete-time linear periodic systems. The new procedure is general being applicable to both standard as well as descriptor periodic systems with time ...

Drivers of Scope 3 Emissions Disclosure Quality—CDP Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Scope 3 emissions account for a significant portion of a supply chain's carbon footprint, yet very little research explores the key drivers of high‐quality Scope 3 disclosures. Additionally, while climate governance is a vital part of both improving carbon performance and ensuring corporate accountability, its broader impact on disclosure ...
