Kinematic precision of gear trains [PDF]

open access: yes
Kinematic precision is affected by errors which are the result of either intentional adjustments or accidental defects in manufacturing and assembly of gear trains. A method for the determination of kinematic precision of gear trains is described.

Clinical and demographic characteristics of adolescents, emerging adults, and young adults presenting to an emergency department following a suicide attempt

open access: yesJCPP Advances, EarlyView.
Abstract Introduction Suicide is a significant public health concern and the second leading cause of death in adolescents and young adults. This study sought to better understand differences in demographic and clinical characteristics of young people who attempted suicide during three phases of this developmental period: late adolescence (14–17 years),

Dynamics of early planetary gear trains [PDF]

open access: yes
A method to analyze the static and dynamic loads in a planetary gear train was developed. A variable-variable mesh stiffness (VVMS) model was used to simulate the external and internal spur gear mesh behavior, and an equivalent conventional gear train ...

Multidexterity: Reframing Strategic Agility for Hyper‐Transformation

open access: yesStrategic Change, EarlyView.
ABSTRACT Organizations experiencing hyper‐transformation—continuous, multidimensional, accelerated, and simultaneous organizational changes—face some limitations in traditional strategic agility and ambidexterity frameworks. Current strategic agility emphasizes rapid responsiveness but insufficiently addresses the nuanced management of varying speeds ...

A Normative Modeling Method for Complex Gear Coupled Rotor-bearing System Dynamics

open access: yesJixie chuandong, 2023
Due to the coupling effect of gears, the vibration of each rotor in the gear rotor bearing system is coupled and affected by each other. The study of the dynamics of the gear rotor bearing system must be analyzed based on a systematic and holistic ...

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]

open access: yes
A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear

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 ...

Surface fatigue life of M50NiL and AISI 9310 spur gears and R C bars [PDF]

open access: yes
Spur gear endurance tests and rolling element surface fatigue tests were conducted to study vacuum induction melted, vacuum arc remelted (VIM-VAR) M50NiL steel for use as a gear steel in advanced aircraft applications, to determine its endurance ...

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

open access: yesStrategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.
