Shang, Y. (author)Transition zones in railway tracks, which occur at changes in track form and or substructure properties, are known to cause issues with track degradation. Examples can be found where a track section, usually a ballast track, transits to a slab track to cross a roadway or waterway through supporting structures such as bridges, level crossings,...doctoral thesis 2024

Vulnerability Assessment of Modern Power Systems: Voltage Stability and System Strength PerspectivesBoricic, Aleksandar (author)Climate change is one of the most dangerous and simultaneously most complex threats humanity has ever faced. The key response to this threat has been an unprecedented strategic shift in the energy sector, known as the<i> energy transition</i>. Electricity powers the modern world and is at the very centre of the energy transition. The shift to...doctoral thesis 2024

Alkharraa, H.S.H. (author)Oil exploitation of tight reservoirs has gained significant importance lately. Some researchers have defined tight reservoirs as those characterized with permeability lower than 0.1 mD. However, permeability is an absolute value, and tight reservoirs have complex pore systems that require a detailed geological and petrophysical rock...doctoral thesis 2024

Dorenbos, P. (author)The U-value defined as the energy difference between the Eu<sup>4+/3+</sup> and Eu<sup>3+/2+</sup> charge transition levels (CTLs) is the most important parameter in constructing vacuum referred binding energy diagrams (VRBEs) with all the lanthanide CTLs with respect to the vacuum level of energy. The parameter is difficult to determine from...journal article 2024

Jain, A. (author), Marykovskiy, Yuriy (author), Metrikine, A. (author), van Dalen, K.N. (author)Railway transition zones (RTZs) are regions where abrupt track stiffness changes occur that may lead to dynamic amplifications and subsequent track deterioration. The design challenges for these zones arise due to variations in material properties in both the depth (trackbed layers composed of different materials) and longitudinal directions of...journal article 2024

Kong, I. (author), Janssen, M.F.W.H.A. (author), Bharosa, Nitesh (author)By utilizing the properties of quantum mechanics, quantum computers have the potential to factor a key pair of a large prime number and break some of the core cryptographic primitives that most information infrastructures depend on. This means that today's widely used cryptographic algorithms can soon become unsafe and need to be modified...journal article 2024

Gürsan, C. (author), de Gooyert, V. (author), de Bruijne, M.L.C. (author), Raaijmakers, J. (author)District heating systems are considered a feasible heating alternative to replace natural gas to mitigate emissions in cities. However, urban transitions are very complex because energy systems often operate in densely populated areas, which gives rise to all kinds of interdependencies in cities. These interdependencies can result in...journal article 2024
