Considerations for Quantitative NDE and NDE Reliability Improvement

, 1983
A challenge has been presented to the scientific community to apply “first principles” to the understanding, prediction, and control of nondestructive evaluation (NDE) processes and applications. The success of the program is evident in the attention of new researchers and in the diversity of scientific specializations that have been directed to NDE ...

Architecting and Industrializing Advanced Production and Manufacturing Systems for Critical Industries

Systems Engineering, EarlyView.
ABSTRACT Advanced production systems play a vital role in modern society. Such systems are developed and industrialized over multiple years and at great expense. The complexities of these systems are exacerbated in the case of metal additive manufacturing, which involves numerous process variables and relies on various auxiliary systems.

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

A cross‐sectional and prospective examination of alcohol use and misuse among adult twin and sibling pairs discordant for neighborhood socio‐economic disadvantage

Addiction, EarlyView.
Abstract Aim To determine whether the association between neighborhood disadvantage and alcohol use and misuse can be explained by a potentially causal effect of neighborhoods or by between‐family genetic and environmental confounding. Design Cross‐sectional and prospective discordant twin and sibling study.

Infrared Thermographic Assessment of Fatigue Behavior in Bolted Composite Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study investigates the temperature evolution of bolted thick glass fiber reinforced polymer composites during fatigue testing. Three different adherend thicknesses (8, 10, and 12 mm) and three different bolt tightening torques (30, 40, and 50 N·$$ \cdotp $$m were considered to evaluate the effects of adherend thickness and bolt tightening

Acoustic Reconstruction for Photothermal Imaging

Bioengineering, 2018
Pulsed illumination of a sample, e.g., of a biological tissue, causes a sudden temperature increase of light absorbing structures, such as blood vessels, which results in an outgoing acoustic wave, as well as heat diffusion, of the absorbed energy.

CH50 as a Clinically Useful Biomarker of Disease Activity and Antihistamine Resistance in Chronic Spontaneous Urticaria: An Observational Ambispective Single‐Center Study

International Journal of Dermatology, EarlyView.
Personalized CSU care guided by CH50. ABSTRACT Background Chronic spontaneous urticaria (CSU) is frequently refractory to guideline‐based therapy, highlighting the need for predictive biomarkers. Dysregulation of the complement system has been implicated in CSU severity, but global complement activity has not been systematically evaluated.

Early‐life pathways to inequalities in child mental health: evidence from eight birth cohorts

Journal of Child Psychology and Psychiatry, EarlyView.
Background Socioeconomic inequalities in children's emotional and behavioural problems are already present at school entry. We examined associations between early‐life socioeconomic conditions and children's externalising and internalising problems and assessed whether early‐life risk factors mediated these associations.
