(author), Hollander, Daan A.M.J. (author), ten Dam, Marc A.G.J. (author)Background: Dialysis patients are confronted with numerous, complex problems, which make it difficult to identify individual patient's most prominent problems. The objectives of this study were to (1) identify dialysis patients' most prominent problems from a patient perspective and (2) to calculate disease-specific norms for questionnaires...journal article 2022

Hermans, Max (author)The current ATC system is seen as the most significant limitation to coping with an increased air traffic density. Transitioning towards an ATC system with a high degree of automation is essential to cope with future traffic demand of the airspace. In recent studies, reinforcement learning has shown promising results automating Conflict...master thesis 2021

Brouwer, Juliette (author), van Eck, Miriam (author), Hermans, Joëlle (author), Louwen, Tijmen (author), Rensman, Cynthia (author)Human driven pollution is causing irreversible damage to the habitability of our planet. Due to these environmental concerns, it has become imperative to move away from petrochemical dependency as this industry contributes significant greenhouse gases causing air, soil and water pollution. About 85% of the petrochemical industry that travels...student report 2021

Jansen, B. (author), Hermans, Felienne (author)The use of spreadsheets in industry is widespread. It is known that spreadsheets have an average life span of five years, and during this life span, they are used on average by thirteen different persons. Consequently, spreadsheets need maintenance, and knowledge about the spreadsheet needs to be transferred from one user to another. To minimize...conference paper 2021

Ebrahimi, Amin (author), Kleijn, C.R. (author), Hermans, M.J.M. (author), Richardson, I.M. (author)Internal flow behaviour and melt-pool surface oscillations during arc welding are complex and not yet fully understood. In the present work, high-fidelity numerical simulations are employed to describe the effects of welding position, sulphur concentration (60-300 ppm) and travel speed (1.25-5 mms-1) on molten metal flow dynamics in fully...journal article 2021

Ebrahimi, Amin (author), Babu, A. (author), Kleijn, C.R. (author), Hermans, M.J.M. (author), Richardson, I.M. (author)One of the challenges for development, qualification and optimisation of arc welding processes lies in characterising the complex melt-pool behaviour which exhibits highly non-linear responses to variations of process parameters. The present work presents a computational model to describe the melt-pool behaviour in root-pass gas metal arc...journal article 2021

Fu, J. (author), Richardson, I.M. (author), Hermans, M.J.M. (author)Oxide dispersion-strengthened (ODS) Eurofer steel was laser welded using a short pulse duration and a designed pattern to minimise local heat accumulation. With a laser power of 2500 W and a duration of more than 3 ms, a full penetration can be obtained in a 1 mm thick plate. Material loss was observed in the fusion zone due to metal...journal article 2021

Butsch, Carsten (author), Chakraborty, Shreya (author), Gomes, S.L. (author), Kumar, Shamita (author), Hermans, L.M. (author)India’s urbanisation results in the physical and societal transformation of the areas sur-rounding cities. These periurban interfaces are spaces of flows, shaped by an exchange of matter, people and ideas between urban and rural spaces—and currently they are zones in transition. Periur-banisation processes result inter alia in changing water...journal article 2021

(author), Slangen, Aimée B.A. (author)The effective climate sensitivity (EffCS) of models in the Coupled Model Intercomparison Project 6 (CMIP6) has increased relative to CMIP5. We explore the implications of this for global mean sea-level (GMSL) change projections in 2100 for three emissions scenarios. CMIP6 projections of global surface air temperature are substantially higher...journal article 2021
