Liu, Haoyuan (author), Pisano, F. (author), Jostad, Hans Petter (author), Sivasithamparam, Nallathamby (author)Offshore monopiles accumulate permanent tilt under long-lasting cyclic environmental loads. Accurate prediction of monopile tilt is key to assessing their serviceability, and requires a fundamental understanding of loading history effects. While both experimental and numerical studies are shedding light on this matter, this work uses step-by...journal article 2022

Cunningham, H. J. (author), Higgins, C. (author), van den Bremer, T.S. (author)Recently, a number of authors have used global particle tracking simulations to identify the effect that different surface currents have on marine litter accumulation, including the role of surface waves through the Stokes drift. However, in the upper-ocean boundary layer and in the presence of the Coriolis force, a wave-driven Eulerian flow...journal article 2022

Ma, L. (author)Complex systems are made up of many interconnected components. The interactions between components further produce emerging complex collective behaviors. In most cases, a complex system can be represented as a network in which the nodes represent the elements and the connected links illustrate the interactions. The spreading process is one of...doctoral thesis 2021

Canongia Lopes Correia Diniz, Beatriz (author)Phosphate accumulating organisms (PAOs) perform a storage polymer metabolism within an anaerobic-aerobic cycle. Anaerobically, PAOs take up volatile fatty acids (VFA) and store them as poly-ẞ-hydroxyalkanoates (PHA). The energy (mainly ATP) necessary for the transport and storage of VFA (and general maintenance) is obtained through the cleavage...master thesis 2021

Deul, Marije (author)The current fatigue assessment methods for naval ships are intentionally conservative. This is in part due to uncertainties in the fatigue capacity (i.e. fatigue resistance) of the ship: the nominal and hot spot structural stress incorporate implicit conservatism due to the inherent data-scatter and the Linear Damage Accumulation Model (LDAM) by...master thesis 2021

Nunes, Cristiana (author), Godts, Sebastiaan (author), Maria Aguilar Sanchez, Asel (author), Slížková, Zuzana (author), Lubelli, B. (author)The RILEM TC 271-ASC is currently developing a new ageing test to assess the<br/>resistance of porous building materials to salt crystallisation. The new test consists of two phases: salt accumulation and damage propagation. This paper focuses on the salt accumulation phase; this phase should promote salt crystallisation close to the evaporative...conference paper 2021

Buchner, A.J.L.L. (author), Muller, K. (author), Mehmood, J. (author), Tam, D.S.W. (author)The accumulation of motile cells at solid interfaces increases the rate of surface encounters and the likelihood of surface attachment, leading to surface colonization and biofilm formation. The cell density distribution in the vicinity of a physical boundary is influenced by the interactions between the microswimmers and their physical...journal article 2021

Ma, L. (author), Sanders, Jaron (author)We study a classical model for the accumulation of errors in multi-qubit quantum computations. By modeling the error process in a quantum computation using two coupled Markov chains, we are able to capture a weak form of time-dependency between errors in the past and future. By subsequently using techniques from the field of discrete...conference paper 2021

Wesseling, Emilie (author)Of the world's population, 59% of the people are not connected to a sewer system and use on-site sanitation (OSS) systems. A large amount of these systems is unsafe. The ultimate goal of this research is to gain knowledge on manners to improve and monitor the safety of on-site sanitation (OSS) systems. The performance and safety of OSS systems...master thesis 2020

Hendriks, Céline (author)In 2017 the island Sint Maarten was hit by hurricane Irma. Approximately ninety-one per cent of the build environment was damaged. This made the existing housing shortage, caused by a growing population, even more significant. Now, three years later, the residential area of Philipsburg is mostly deserted. With the departure of its residents, the...master thesis 2020
