Determination of organic fluorinated compounds content in complex samples through combustion ion chromatography methods: a way to define a “Total Per- and Polyfluoroalkyl Substances (PFAS)” parameter?

Emerging contaminants are a growing concern for scientists and public authorities. The group of per-polyfluoroalkyl substances (PFAS), known as ‘forever chemicals', in complex environmental liquid and solid matrices was analysed in this study. The development of global analytical methods based on combustion ion chromatography (CIC) is...

Learning to recognise words using visually grounded speech

We investigated word recognition in a Visually Grounded Speech model. The model has been trained on pairs of images and spoken captions to create visually grounded embeddings which can be used for speech to image retrieval and vice versa. We investigate whether such a model can be used to recognise words by embedding isolated words and using...

A multidimensional examination of performances of HSR (High-speed rail) systems

This paper deals with a multidimensional examination of the infrastructural, technical/technological, operational, economic, social, and environmental performances of high-speed rail (HSR) systems, including their overview, analysis of some real-life cases, and limited (analytical) modeling. The infrastructural performances reflect design and...

Comparison of quay wall designs in concrete, steel, woord and composites with regard to the co2-emission and the life cycle analysis

In this paper quay wall designs in different materials are compared with regard to the CO2-emission and the Life Cycle Analysis (LCA). For this study the requirements and boundary conditions of the quay wall in the Euromax Terminal, the Port of Rotterdam, have been used. An overview of preliminary designs of the tender phase with a concrete...
