Text Clustering with Large Language Model Embeddings
International Journal of Cognitive Computing in Engineering
Text clustering is an important method for organising the increasing volume of digital content, aiding in the structuring and discovery of hidden patterns in uncategorised data. The effectiveness of text clustering largely depends on the selection of textual embeddings and clustering algorithms. Thi…

Experimental study of bending capacity of steel pipes
— 2025
This work presents an experimental investigation into bending capacity of steel pipes, analysing how material properties, local defects, and loading conditions influence their structural performance. Three point bending tests were conducted on steel pipes with an outer diameter of 60 mm and wall thi…

13th Mediterranean Combustion Symposium
The combustion of natural gas/hydrogen mixtures is experimentally investigated in a laboratory-scale combustor. A distinctive feature of this combustor is the injection of secondary air through holes in a plenum located at the top of the combustor in a direction opposite to the fuel jet, which is su…
