CNN‐based multi‐output regression model to estimate infrastructural surface crack dimensions adopting a generalised patch size and FWHM‐based width quantification

Digital Twins and Applications, Volume 2, Issue 1, January/December 2025.
Multi‐output regression based on convolution neural network is proposed to estimate crack properties directly from an input image. Ablation study of the top 3 models. Mathematical morphology for efficient crack segmentation and FWHM‐based crack‐width quantification. Abstract To cater the need for real‐time crack monitoring of infrastructural facilities,

Non-destructive Thermal Monitoring of Temperature and Flow Rate of the Heat Carrier in a Heating Device [PDF]

E3S Web of Conferences
Conducting various calculations for the heating system of a building under operational conditions is impossible without knowledge of the temperature and flow rate of the heat carrier at specific points. Contact measurement means are not always applicable,

Determination of Groove Filling Levels of Pressed Pipe-Fitting Connections Using Phased Array Ultrasound Evaluated by a CNN

Applied Sciences
In this paper, a method for determining the filling level of grooves (1 mm (W) × 0.25 mm (H)) in pressed titanium pipe-fitting joints is presented. The joints are inspected in a water bath using a 20 MHz phased array ultrasound, and the acquired raw B ...
