Vibration Analysis of Viscoelastic Timoshenko Cracked Beams with Massless Viscoelastic Rotational Spring Models

open access: yesJournal of Applied Mathematics, 2023
Based on the equivalent bending stiffness of the viscoelastic cracked beam with open cracks, the corresponding complex frequency characteristic equations of a Timoshenko viscoelastic cracked beam are obtained by using the method of separation of ...

Vibration Based - Crack Detection in Simplified Wind Turbine Blades Using Artificial Neural Networks [PDF]

open access: yesEngineering and Technology Journal, 2014
Wind turbine blades are complicated components for inspection by non-destructive techniques because they are multi-layered, have variable thickness and are made of anisotropic materials. This paper proposes the use of Artificial Neural Networks (ANN) for

Cracking Open the News Feed

open access: yesJournal of Quantitative Description: Digital Media, 2021
In this study, we analyze for the first time newly available engagement data covering millions of web links shared on Facebook to describe how and by which categories of U.S. users different types of news are seen and shared on the platform. We focus on articles from low-credibility news publishers, credible news sources, purveyors of clickbait, and ...

Cracking “Open” Technology in Ecohydrology [PDF]

open access: yes, 2020
In recent years, the adjective “open” has been applied to many aspects of scientific knowledge discovery and dissemination, including open-source software and hardware, open access journal articles, massive open online courses, and open data. Applying the term open to these entities emphasizes an intention for them to be accessible—a quality ...

The Effects of Breathing Behaviour on Crack Growth of a Vibrating Beam

open access: yesShock and Vibration, 2018
The effects of breathing behaviour on the dynamic response and crack growth are studied through a cracked cantilever beam. The main goal is to reveal the coupling mechanism of dynamic response and crack growth by employing a plain single-degree-of ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
