Characteristics Regarding Lift-Off Intersection of Pulse-Modulation Eddy Current Signals for Evaluation of Hidden Thickness Loss in Cladded Conductors [PDF]

open access: yesSensors, 2019
The cladded conductor is broadly utilized in engineering fields, such as aerospace, energy, and petrochemical; however, it is vulnerable to thickness loss occurring in the clad layer and nonconductive protection coating due to abrasive and corrosive ...

Age Influences Loss Aversion Through Effects on Posterior Cingulate Cortical Thickness

open access: yesFrontiers in Neuroscience, 2021
Decision-making strategies shift during normal aging and can profoundly affect wellbeing. Although overweighing losses compared to gains, termed “loss aversion,” plays an important role in choice selection, the age trajectory of this effect and how it ...

Change in brain volume and cortical thickness after behavioral and surgical weight loss intervention

open access: yesNeuroImage: Clinical, 2019
Obesity is associated with reduced cortical thickness and brain volume, which may be related to poor nutrition. Given that brain atrophy in anorexia nervosa recovers with nutritional improvements and weight gain, it is worth examining how brain structure

Improvement of transmission loss of bellows through thickness improvement and structural modification

open access: yesAdvances in Mechanical Engineering, 2021
The bellows of the vehicle are vulnerable to noise because of the low transmission loss among the components. Therefore, in this study, we modified the thickness and the structure of the bellows to improve transmission loss.

Small Ultrasound-Based Corrosion Sensor for Intraday Corrosion Rate Estimation

open access: yesSensors, 2022
The conventional way of studying corrosion in marine environments is by installing corrosion coupons. Instead, this paper presents an experimental field study using an unattended corrosion sensor developed on the basis of ultrasound (US) technology to ...

Ultrasound-Based Smart Corrosion Monitoring System for Offshore Wind Turbines

open access: yesApplied Sciences, 2022
The ultrasound technique is a well-known non-destructive and efficient testing method for on-line corrosion monitoring. Wall thickness loss rate is the major parameter that defines the corrosion process in this approach.

Comparison of Multi-criteria Decision Making Methods for Selection of Handmade Carpets

open access: yesJournal of Natural Fibers, 2022
Selecting the best carpet from a set of available alternatives for a particular end-use situation is a difficult job because of association with multiple decision criteria. Three multicriteria decision-making (MCDM) methods, i.e., weighted sum model (WSM)

Wing-feather loss in white-feathered laying hens decreases pectoralis thickness but does not increase risk of keel bone fracture

open access: yesRoyal Society Open Science, 2022
Feather loss in domestic chickens can occur due to wear and tear, disease or bird-to-bird pecking. Flight feather loss may decrease wing use, cause pectoral muscle loss and adversely impact the keel bone to which these muscles anchor.

Maximum Thickness Location Selection of High Subsonic Axial Compressor Airfoils and Its Effect on Aerodynamic Performance

open access: yesFrontiers in Energy Research, 2021
Solidity and camber angle are key parameters with a primary effect on airfoil diffusion. Maximum thickness location has a considerable impact on blade loading distribution. This paper investigates correlations of maximum thickness location, solidity, and

Mass Balances of a Drained and a Rewetted Peatland: on Former Losses and Recent Gains

open access: yesSoil Systems, 2020
Drained peatlands are important sources of greenhouse gases and are rewetted to curb these emissions. We study one drained and one rewetted fen in terms of losses—and, after rewetting—gains of organic matter (OM), carbon (C), and peat ...
