Cyber technologies are offering new horizons for quality monitoring and control in manufacturing and safety assurance of physical assets in service. The line between nondestructive evaluation (NDE) and Industry 4.0 is getting blurred since both are sensory data-driven domains. This multidisciplinary approach has led to the emergence of a new capabi...
Digital technologies provide significant efficiency gains to NDE (Nondestructive Evaluation) procedures. Digitalization of NDE further enhances its effectiveness and simplifies the processes. Digital transformation at the NDE ecosystem level can create unprecedented value for multiple stakeholders simultaneously. The aspects of technology (chapter...
The world of nondestructive evaluation (NDE) has seen digitization since the third revolution. Over the last decade or so, digitalization has also been observed to a point where it is now ready for digital transformation, in sync with the fourth industrial revolution. The intermediary step of digitalization overlaps the third and fourth revolution...
Just a few years back, when the term “NDE 4.0” was introduced at the ASNT Annual Conference, it was also mentioned it would become mainstream by the mid-2020s. At the recently concluded WCNDT 2024 in Korea, over half the presentations featured significant digital content—a trend similarly observed at ASNT 2024. As manufacturing is now rapidly under...
The cyber world of information technologies, digitization, digital transformation, Industry 4.0, and NDE 4.0 presents similar complexities to the physical world, including threats such as: loss of information, human error, ethical lapses, malicious intent, and political interests.

If digital transformation is not the ultimate goal, then what is? There are many common myths and misconceptions surrounding digital transformation. Technology plays a role, to be sure, but it’s not the only essential ingredient. A true digital transformation strategy requires many incremental steps involving changes in culture, business models, an...
Data is the backbone of digitalization, digital transformation, and NDE 4.0, but

Across so many industries, non-destructive evaluation has proven its worth time and again through quality and safety assurance of valuable assets. Yet, over time, it became underappreciated in business decisions. In most cases, the data gathered by NDT is used for quality assurance assessments resulting in binary decisions. And we seem to miss out...

Dear Digital Transformation specialists & experts,
I bet you can also see the impact of the digital transformation of companies on various departments, employees, customers, patients, suppliers, and on society.
We have started together with the Springer Nature Journal "Digital Society" a special issue on "The Impact of Digital Transformation on Society". With your experience, I bet you can add some fascinating papers to this special issue.
Thanks a lot to Federica Russo, editor-in-chief of Digital Society, for trusting us with this special issue.
The term NDE 4.0 originates from the idea of the fourth industrial revolution, or Industry 4.0. It is defined as the cyber-physical confluence between non-destructive testing and evaluation (NDT&E) and digital technologies including Artificial Intelligence, Digital Twins, Robotics, Advanced Sensing, and Sensor Networks. These ideas have the potential to become a cyber-physical NDE ecosystem (similar to the ongoing transformations in the medical and mobile communication sectors) that reshapes many traditional NDE, structural health monitoring, and prognoses. NDE 4.0 is also about the inspection of new generations of multi-functional components like additively manufactured parts and about fully automated inspection systems integrated into smart factories. Interest in this interdisciplinary field is growing and has the potential to involve all aspects of NDE. This special issue is focused on NDE 4.0, especially from a physics perspective.

Manchmal überrascht einen das Leben und die Aktionen von so manchen Mitmenschen und es zeigt recht deutlich warum in Deutschland die Digitalisierung und Digitale Transformation nicht vorankommt:
Der englische Wikipedia Artikel zu ZfP 4.0 wurde von Nathan Ida erstellt (ich habe mich extra nicht bei der ursprünglichen Erstellung eingemischt damit keiner den Punkt Interessenskonflikt aufführen kann) und es hat über ein halbes Jahr gedauert bis der Artikel freigegeben war.
Nachdem der Artikel freigegeben war habe ich ihn dann übersetzt. Möglichst 1:1.
Jetzt kommt ein, anscheinend recht aktives Mitglied der Wikipedia Gemeinde mit dem Pseudonym darkking3, und stellt einen Löschantrag: "Der Autor des Artikels ist identisch mit dem Verfasser der als relevanzgebenden ersten Referenz. Dementsprechend liegt mindestens eine Eigenreferenzierung und damit ein Interessenkonflikt vor."
darkking3 schreibt weiter:
"Möglicherweise (bzw. für mich sehr wahrscheinlich) fällt der Artikel auch in nicht offengelegtes bezahltes Schreiben."
Hier der link zum Löschantrag: https://de.wikipedia.org/wiki/Wikipedia:L%C3%B6schkandidaten/20._Juni_2023#Zerst%C3%B6rungsfreie_Pr%C3%BCfung_4.0
Auf Argumente dass ich den Artikel gar nicht geschrieben habe sondern nur übersetzt geht er nicht ein sondern bleibt bei seinem Argument.
Interessant finde ich auch dieses Argument von darkking3: "Auch Beteuerungen dahingehend, dass keine kommerziellen Interessen verfolgt werden, sind wertlos, da sie nicht prüfbar sind." Ist das nicht eine allgemeine Schuldvermutung???
Interessant finde ich auch folgende Statements:
- "Bei den ganzen Wortmeldungen sollte ggf. mal darüber nachgedacht werden, sich vielleicht zuerst der 29 aufgezählten Verfahren anzunehmen, fehlende ZfP Artikel zu erstellen und bestehende zu verbessern, anstatt neue anzulegen und zu versuchen, gefühlte Buzzwords zu etablieren."
- "1. Der deutsche Begriff, im Gegensatz zum englischen, existiert in der Fachwelt so nicht. Es handelt sich um Begriffsetablierung. 2. Mindestens der Abschnitt "Geschichte" ist unbelegte Theoriefindung. 3. Die Belegarbeit ist bestenfalls unsauber, mit zahlreichen Einzelnachweisen die gemachte Aussagen nicht belegen bzw. bei denen es sich vorsichtig formuliert um Theoriefindung handelt. Sekundärliteratur ist Mangelware. In dieser Form kann man das verlustfrei löschen"
- "Schwurbel-Beitrag, der bereits in der Einleitung einen kompletten Ausfall darstellt"
Wer hat schon einmal etwas ähnliches mit WIkipedia erlebt?
Sizing indications with ultrasonics can be challenging. For large indications sizing by probe travel is appropriate, for indications smaller than the beam width amplitude-based sizing. But what about indications smaller than the wavelength? This video is all about those TINY defects and why you should NEVER use Flat Bottom Holes smaller than ¼ of the wavelength!
