Verhagen, R.S. (author), Neerincx, M.A. (author), Tielman, M.L. (author)Because of recent and rapid developments in Artificial Intelligence (AI), humans and AI-systems increasingly work together in human-agent teams. However, in order to effectively leverage the capabilities of both, AI-systems need to be understandable to their human teammates. The branch of eXplainable AI (XAI) aspires to make AI-systems more...conference paper 2021

Haji Aghajany, S. (author), Amerian, Yazdan (author), Verhagen, S. (author), Rohm, Witold (author), Schuh, Harald (author)Tropospheric wet delay, the main source of which is water vapor, is one of the major factors affecting the accuracy of positioning techniques using microwave. Tropospheric tomography is a powerful method to reconstruct the water vapor content in four-dimensional (4D) space. This paper studies the effect of using function-based and voxel-based...journal article 2021

Massart, Philippe F.R. (author), Dhanisetty, V.S.V. (author), Kassapoglou, C. (author), Verhagen, W.J.C. (author), Curran, R. (author)This paper proposes an analytical model that uses historical damage dimension data to deduce physical impactor characteristics (size and energy) that has caused a certain resulting damage. Maintenance tasks occur in operations due to impact, however the source of the damage caused in the event remains in most cases unknown. Consequently, by...journal article 2020

Haji Aghajany, S. (author), Amerian, Yazdan (author), Verhagen, S. (author), Rohm, Witold (author), Ma, H. (author)The water vapor content in the atmosphere can be reconstructed using the all-weather condition troposphere tomography technique. In common troposphere tomography, the water vapor of each voxel is represented by an unknown parameter. This means that when the desired spatial resolution is high or study area is large, there will be a huge number of...journal article 2020

Verhagen, K.J.A. (author), van Gulik, W.M. (author), Wahl, S.A. (author)Redox metabolism plays an essential role in the central metabolic network of all living cells, connecting, but at the same time separating, catabolic and anabolic pathways. Redox metabolism is inherently linked to the excretion of overflow metabolites. Overflow metabolism allows for higher substrate uptake rates, potentially outcompeting...review 2020
