Considerations for Quantitative NDE and NDE Reliability Improvement [PDF]

open access: yes, 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 ...

Ultrasound nondestructive evaluation (NDE) imaging with transducer arrays and adaptive processing [PDF]

open access: yes, 2012
This paper addresses the challenging problem of ultrasonic non-destructive evaluation (NDE) imaging with adaptive transducer arrays. In NDE applications, most materials like concrete, stainless steel and carbon-reinforced composites used extensively in ...

Miniature mobile sensor platforms for condition monitoring of structures [PDF]

open access: yes, 2009
In this paper, a wireless, multisensor inspection system for nondestructive evaluation (NDE) of materials is described. The sensor configuration enables two inspection modes-magnetic (flux leakage and eddy current) and noncontact ultrasound.

NDE 4.0: a Five Years Success Story

open access: yes, 2023
In my plenary lecture at the SPIE symposium “Smart Structures and NDE” 2017, I introduced the name NDE 4.0 for the first time as part of the Industrial Revolution 4.0. That was almost exactly 5 years ago. A few months later, several organizations started

Migraine aura, a predictor of near-death experiences in a crowdsourced study [PDF]

open access: yesPeerJ, 2019
Background Near-death experiences (NDE) occur with imminent death and in situations of stress and danger but are poorly understood. Evidence suggests that NDE are associated with rapid eye movement (REM) sleep intrusion, a feature of narcolepsy. Previous

Incidence of near-death experiences in patients surviving a prolonged critical illness and their long-term impact: a prospective observational study

open access: yesCritical Care, 2023
Background So far, the few prospective studies on near-death experience (NDE) were carried out only in intensive care unit (ICU) patients with homogeneous aetiologies, such as cardiac arrest or trauma survivors.
