This paper introduces a resource‐aware Contrastive Scattering Meta‐Learning (CSML) framework for acoustic anomaly detection. By leveraging training‐free wavelet scattering and metric‐based meta‐learning, the model achieves competitive performance with only 50 K learnable parameters—a 98% reduction compared to state‐of‐the‐art frameworks—enabling ...

Effect of periodic ultrasonic vibration on forming and properties of 316L stainless steel’s TIG weld
To deal with large heat input and improve the structure and performance of traditional TIG welding, ultrasonic vibration was adopted and directly acted on the base material to introduce periodic ultrasonic vibration into the molten pool, and the ...

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Investigating Nucleation Inhibition in the Dehydrogenation of Perhydro Benzyltoluene
Nucleation can profoundly influence mass transport and the performance of reactive systems. Building on observations from other LOHC systems, this work demonstrates that gas bubble nucleation enhances hydrogen release during perhydro benzyltoluene dehydrogenation.

Fatigue of weldments with welding defects – defect sizing, crack nucleation and crack growth rate
Abstract Ultrasonic inspections of weldments in some existing bridges revealed the presence of cold cracks, slag inclusions, and porosities of sizes beyond todays acceptance criteria. We conducted a study on the prediction of the fatigue life of these weldments. This paper presents the models and main findings of the study.
