Sharma, Revanth (author)One of the novel methodologies in computational physics research is to use mimetic discretisation techniques. Among these, the mimetic spectral element method holds special promise as it not only has the benefits of mimetic methods but also the additional benefit of higher-order discretisations using higher polynomial degrees. These methods are...master thesis 2023

Hoekstra, Bas (author)The Dutch construction sector is confronted with a complex and challenging situation. The majority of the infrastructural elements in the Netherlands were built in the 1950s and 60s, which means they are approaching the end of their lifespan. This state, in combination with backlogged maintenance and budget cuts, created a significant and urgent...master thesis 2023

Moradi Sepahvand, M. (author), Amraee, Turaj (author)This paper presents a multi-stage expansion model for the co-planning of transmission lines, battery energy storage (ES), and wind power plants (WPP). High penetration of renewable energy sources (RES) is integrated into the proposed model concerning renewable portfolio standard (RPS) policy goals. The possibility of bundling existing...journal article 2023

Pachos-Fokialis, N. (author), Galanaki, Eleanna (author), van der Heijden, Beatrice I.J.M. (author)Previously, scholars have studied the need for implementing different human resource (HR) configurations that foster aging employees' outcomes, but there is a lack of evidence at the group level. Using the framework of Social Exchange Theory, coupled with the Selection, Optimization, and Compensation theory, we examine associations between...journal article 2023

Loor, Stephan (author)In the past few years, the search for good quantum low density parity check (qLDPC) codes suddenly took flight, and many different constructions of these codes have since been presented, including many product constructions. As these code constructions have a natural interpretation in the language of homology, this thesis studies the interplay...master thesis 2022

Sun, Zhu (author), Yang, J. (author), Feng, Kaidong (author), Fang, Hui (author), Qu, Xinghua (author), Ong, Yew Soon (author)Product bundling is a commonly-used marketing strategy in both offline retailers and online e-commerce systems. Current research on bundle recommendation is limited by: (1) noisy datasets, where bundles are defined by heuristics, e.g., products co-purchased in the same session; and (2) specific tasks, holding unrealistic assumptions, e.g.,...conference paper 2022

Zaaijer, Floris (author)Mechanical air entrapment, void compression and void dissolution are the main mechanisms behind void formation in liquid composite molding. Mechanical air entrapment is induced by the highly non-uniform geometry at the meso- and micro-scale and the heterogeneous properties of the reinforcing material. This results in differences in the velocity...master thesis 2021

Bertocchi, F. (author)Flows in rod bundles are common to many industrial applications such as heat exchangers or some types of nuclear reactors. The core of many classes of nuclear reactors can be easily sketched as a bundle of rods, the fuel pins, inmmersed in an axial ow of coolant that removes the heat produced by the fission reaction. Coupling this geometry to an...doctoral thesis 2020

Los, J. (author), Schulte, F. (author), Gansterer, Margaretha (author), Hartl, Richard F. (author), Spaan, M.T.J. (author), Negenborn, R.R. (author)While collaborative vehicle routing has a significant potential to reduce transportation costs and emissions, current approaches are limited in terms of applicability, unrealistic assumptions, and low scalability. Centralized planning generally assumes full information and full control, which is often unacceptable for individual carriers....conference paper 2020

Niestijl, Milan (author)Recent progress on the representation theory of certain infinite dimensional gauge groups has raised an interest in the strongly continuous unitary representations of groups of a specific form that satisfy a certain positive energy condition. An equivalent formulation of the positive energy condition is obtained, allowing for a geometrical...master thesis 2019

Bertocchi, F. (author), Rohde, M. (author), Kloosterman, J.L. (author)Gap vortex streets characterise many industrial applications involving rod bundle flows, such as heat exchangers and nuclear reactors. These structures, known as gap vortex streets, may excite the structural components of the bundle to resonance, leading to fretting and fatigue. This work aims to measure these coherent structures and the...journal article 2019

Bertocchi, F. (author), Rohde, M. (author), Kloosterman, J.L. (author)The core of a Liquid Metal Fast Breeder Reactor (LMFBR) consists of cylindrical fuel rods that are wrapped by a helicoidally-wound wire spacer to enhance mixing and to prevent damage by fretting. It is known that the liquid metal close to the rod is forced to follow the wires, and that liquid metal further away from the rod crosses the wires ...journal article 2019

Snijder, A.H. (author), van der Linden, L.P.L. (author), Goulas, C. (author), Louter, P.C. (author), Nijsse, R. (author)The majority of glass used in load-bearing structures is as planar elements. Some projects exist that use linear glass elements. This paper discusses in broad terms the design, engineering, and fabrication of a unique vector active glass structure consisting of glass bundles and partly printed steel connections. A structure was conceived that...journal article 2019

Awadalla, Tarek (author), Voskov, D.V. (author)Gas flow in fractured nano-porous shale formations is complicated by a hierarchy of structural features, ranging from nanopores to hydraulic fractures, and by several transport mechanisms that differ from standard viscous flow used in reservoir modeling. The use of accurate simulation techniques that honor the physical complexity of these...journal article 2018

Soriano Segúra, Clara (author)Introduction <br/>KLM aims to be the “most customer centric, innovative, and efficient European Network Carrier” with a special focus on customer intimacy. However, the current way in which KLM introduces its products to its customers is not aligned with this vision. This misalignment can reduce the company’s performance in relation to other...master thesis 2018

Bertocchi, F. (author), Rohde, M. (author), Kloosterman, J.L. (author)The enhancement of heat transfer from fuel rods to coolant of a Liquid Metal Fast Reactor (LMFR) decreases the fuel temperature and, thus, improves the safety margin of the reactor. One of the mechanisms that increases heat transfer consists of large coherent structures that can occur across the gap between adjacent rods. This work...journal article 2018

Koppenol, D.C. (author)Dermal wounds are a significant global problem; although the treatment of these wounds has improved considerably over the last few decades, a treatment still does not result in a complete regeneration of the injured tissue. Instead, the final outcome of the healing process is scar tissue. The material properties of scar tissue are different from...doctoral thesis 2017
