To prevent climate change, Europe and the world must shift to low-carbon and renewable energies.Hydrogen, as an energy vector, provides viable solutions for replacing polluting and carbon-emitting fossil fuels.Gaseous hydrogen can be stored underground and coupled with existing natural gas pipe networks.Salt cavern storage is the best suited techno

We explore the estimation of a two-dimensional (2D) nonsymmetric coherently distributed (CD) source using L-shaped arrays.Compared with a symmetric source, the modeling and estimation of a nonsymmetric source are more practical.A nonsymmetric CD source is established through modeling the deterministic angular signal distribution function Aluminium

Feature selection has emerged as a craft, using which we boost the performance of our learning model.Feature or Attribute Selection is a data preprocessing technique, where only the most informative features are considered and given to the predictor.This reduces the computational overhead and improves the correctness of the classifier.Attribute Sel

The aim of this paper is to review material properties of a new filling material for cold sleeve.The first experimental measurements were Hygiene and Beauty Products performed on samples to determine required material properties.Then the structural analysis was performed for a pressurized pipe with insufficiently welded root and installed cold slee

This paper dwells on an interesting contrast between Romance (Romanian, Spanish a.o.) and Germanic languages (English, German a.o.) with respect to the syntax and the interpretation of the direct object (DO).One structural difference between these two groups of languages amounts to the fact that the former clitic double (CD) and differentially obje
