The Italian Approach for the Evaluation of the Potential Ecotoxicity of Spoil Material in EPB Excavation

Earth Pressure Balance TBM is currently the most used technology in mechanised tunnelling. The use of EPB-BM requires soil conditioning additives among which the most important is foam to optimise soil properties, stabilise the tunnel face, reduce wear on the TBM equipment and prevent clogging of the screw conveyor, thereby improving operational efficiency. The various parameters for which foam is used in real excavations should be studied in detail in site-specific studies at the design stag...

Interaction-Aware Gaussian Weighting for Clustered Federated Learning

Federated Learning (FL) emerged as a decentralized paradigm to train models while preserving privacy. However, conventional FL struggles with data heterogeneity and class imbalance, which degrade model performance. Clustered FL balances personalization and decentralized training by grouping clients with analogous data distributions, enabling improved accuracy while adhering to privacy constraints. This approach effectively mitigates the adverse impact of heterogeneity in FL. In this work, we ...

Gaborized MCS for Precise Code Phase Offset Estimation in Radionavigation

In radar and radionavigation systems, waveform design optimization has mostly focused on Gabor bandwidth (GB), as a metric to infer code phase offset estimation accuracy. While optimization algorithms have maximized GB w.r.t. to specific design parameters and receiver bandwidth, they lack closedform solutions for pulse shapes. Inspired by Gabor pulse theory, this paper presents a family of waveforms shaping multi-level coded spreading (MCS) coefficients with a Gaussian envelope, namely the Ga...

Exploring Observation-Domain with Nonlinear Time-Series Warping for Aided GNSS Navigation.

This paper investigates the application of sequence matching (SM) techniques to enhance aided GNSS navigation in lunar mission scenarios. Focusing on the challenges of aligning GNSS derived Position, Velocity, and Time (PVT) solutions with pre-designed Aiding Trajectories (ATs) under varying geometric conditions, the study identifies Dynamic Time Warping (DTW) as the most effective SM strategy. The novelty lies in extending nonlinear time-series warping methods towards the exploration of the ...

Real-time thermographic monitoring for automated defect detection in welding

Welding quality is quite critical in manufacturing. This work provides a method to enhance defect detection in robotic welding by combining statistical approaches with real-time thermographic monitoring. A robotic arm welds, and an infrared camera records temperature data. After segmentation and morphological processing, key features are extracted and optionally smoothed (e.g., via Savitzky–Golay). Principal Component Analysis (PCA) reduces dimensionality, and an Isolation Forest then identif...
