Alwani, Neil (author)This study investigates the application of generative models for synthetic data generation in pathway optimization experiments within the field of metabolic engineering. Conditional Variational Autoencoders (CVAEs) use neural networks and latent variable distributions to generate new, plausible data samples. We adapt this model by conditioning...bachelor thesis 2024

van Donselaar, Kevin (author)Large parts of the Netherlands lay below mean sea level. An extensive network of flood protection measures is in place to prevent flooding. Periodic safety assessment and reinforcement are required to guarantee a resilient system. Currently, in the Netherlands, an extensive sea dike reinforcement program is underway to meet the safety standards...master thesis 2023

Sensitivity of the seismic response of monopile-supported offshore wind turbines to soil variabilityPanagoulias, S. (author), de Winter, C. (author), Navalkar, S.T. (author), Nernheim, A. (author)The expansion of the offshore wind industry in areas with high seismicity has led to engineering challenges related to the design of the offshore wind turbines (OWTs). Monopiles, i.e., tubular steel piles of large outer diameter, low aspect ratio (penetration depth over outer diameter), and relatively thin pile wall, are traditionally the...journal article 2023

Le Grand, Oscar (author)Sea level rise will increase the risk of flooding in coastal areas. This poses a risk to the coastal protection as well as rivers and lakes close to the coast. Solutions are needed to cope with this threat. The past decade, nature based solutions have gained significant interest. One of these solutions could be sandy foreshores. Due to the use...master thesis 2022

CAUMO, GIORGIO (author)In the last decades, renewable energies gained an increasing interest due to the environmental awareness of people, especially in the developed countries. Moreover sustainable resources represent a long-term investment full of possibilities of use. <br/>In the Netherlands a technology which is getting more and more popular to produce green...master thesis 2022

van der Werf, Jilles (author)Reliability analysis is a rational method for dealing with uncertainties. It is increasingly used for the design and assessment of (civil) structures. Reliability analysis, possibly in combination with performance data, allows for instance to update (extend) the lifetime of existing quay wall structures. This gives economic advantages when...master thesis 2021

Han, Han (author)Soil properties are spatially variable due to the natural deposition process. Because of this inherent spatial variability, a slope can actually fail along any potential slip surface. A single value of Factor of safety cannot account for this variation dominated the slope stability problem. Probabilistic analysis considering the spatial...master thesis 2021

Huijsman, Douwe (author)There is a lot of uncertainty in climate change developments, and therefore in its consequences. For the flood defence system of the Netherlands, an important consequence of climate change is the sea level rise. Marine locks are large, rigid, and intricate structures, with a required lifespan of at least 100 years, for which often design...master thesis 2021

Verma, Amrit Shankar (author), Jiang, Zhiyu (author), Caboni, Marco (author), Verhoef, Hans (author), van der Mijle Meijer, Harald (author), Castro, Saullo G.P. (author), Teuwen, Julie J.E. (author)Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and maintenance costs. For efficient operation and maintenance, erosion models are required that provide estimates of blade coating lifetime at a real scale. In this study, a statistical rainfall model is established that describes probabilistic...journal article 2021

van Dam, Johan (author)New and existing bridges in the Netherlands must abide by structural safety codes, such as the Eurocode. In this code, structural safety is expressed through the reliability index 훽. For certain reference periods a threshold value for 훽 exists. When applying prescribed load models given in the Eurocode, the structure is guaranteed to at least...master thesis 2020

van Wierst, Bas (author)During construction of breakwaters, adverse weather conditions can result in damage, in the form of reshaping and loss of material to the open work fronts of the structure. Based on literature research, analysis of work methods, analysis of damage to older breakwater projects and interviews, it was deduced that during construction, the open work...master thesis 2019

Anastasiadou, Anastasia (author)Over the last decades, laser scanners are becoming more and more established for the acquisition of geo-information. Depending on the sensor platform where the laser scanners are mounted, there are MLS, ALS and TLS techniques for both indoor and outdoor environments. The high-quality 3D point clouds produced from laser scanners is an important...master thesis 2019

Wu, W. (author), Kolstein, M.H. (author), Veljkovic, M. (author)The orthotropic steel decks (OSDs) are widely used in bridge engineering to support traffic loads. A possible crack, initiating from the weld toe of rib-to-deck welded joint and growing into the deck plate, is studied using linear elastic fracture mechanics. A detailed FE model is created and the results are compared with the fatigue tests...journal article 2019

Korswagen, Paul A. (author), Jonkman, Sebastiaan N. (author), Terwel, K.C. (author)Evaluating and predicting structural damage from multi-hazards is a complex task mainly due to the varying ways in which hazards affect structures. Also, different damage scales that employ different parameters and criteria are used for evaluating the hazards, making a connection between the damage assessment of two or more hazards difficult....journal article 2019

Kolen, B. (author), van Gelder, P.H.A.J.M. (author)It is important for decision-makers in emergency response situations to determine the scope, scale, timing, path and resettlement area of an evacuation decision when there is an imminent threat of flooding. In this paper, a method called the "Evacuation Diagram" is described to support risk-based evacuation planning and decision-making. In...journal article 2018

Csicsek, A. (author)The assessment of rock mechanical data is a fundamental step in the process of evaluating the profitability of an open pit mine. The steepness of bench, interramp and resulting overall slope angles have a direct effect on the stripping ratio, therefore on the profitability of the mining operation. With the recently challenging metal prices in...master thesis 2016
