Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Almost commutative Riemannian geometry: wave operators

open access: yes, 2011
Associated to any (pseudo)-Riemannian manifold $M$ of dimension $n$ is an $n+1$-dimensional noncommutative differential structure $(\Omega^1,\extd)$ on the manifold, with the extra dimension encoding the classical Laplacian as a noncommutative `vector ...

Is Job Embeddedness a Resource? Revisiting the Relationship of Job Embeddedness and Employee Well‐Being: A Meta‐Analytic Investigation

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Job embeddedness (i.e., organizational and community factors that explain why employees remain in their organization) is generally regarded as a positive construct. However, a growing body of research suggests that embeddedness may also have detrimental effects on well‐being, particularly when considering nonwork and cross‐domain outcomes.

A fast and high‐accurate commutation failure identification method for LCC‐HVDC system

open access: yesHigh Voltage
Commutation failure (CF) is one of the most common issues in line‐commuted converter‐based high voltage direct current systems (LCC‐HVDC), leading to critical power system security and stability problems.

CSR disclosure and investment efficiency in MENA countries: The moderating role of CSR committee

open access: yesStrategic Change, EarlyView.
ABSTRACT Corporate social responsibility disclosure (CSRD) is often recognized as a transparency mechanism that allows companies to communicate their commitment to CSR. However, CSRD may also exacerbate agency conflicts. This study addresses these two contrasting perspectives by investigating the impact of CSRD on investment efficiency and exploring ...

Oppression‐based stressors, posttraumatic stress symptoms, and self‐injurious thoughts and behaviors among a national sample of queer adolescents of color

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Oppression‐based stressors (OBS; e.g., heterosexism‐based stressors) are associated with a higher risk of trauma‐related symptoms and self‐injurious thoughts and behaviors (SITB) for queer (e.g., lesbian, gay, bisexual) adolescents. However, prior research has yet to examine posttraumatic stress symptoms (PTSS) and SITB in the context of the ...

Dual Pathways of Loneliness in the Marketplace: Emotional Attachment, Empowerment, and Evaluations of Brand Warmth and Brand Competence

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Loneliness shapes consumer behavior, yet whether it increases preference for warm or competent brands remains unresolved. We argue that this question cannot be answered without distinguishing who is perceived to be lonely. Individual loneliness, which is a person's subjective experience of social disconnection, activates agency‐restoration ...
