Deep Neural Networks (DNNs) have found extensive applications across diverse fields, such as image classification, speech recognition, and natural language processing. However, their susceptibility to various adversarial attacks, notably the backdoor attack, has repeatedly been demonstrated in recent years. <br/>The backdoor attack aims to...

In evolutionary biology, networks are becoming increasingly used to represent evolutionary histories for species that have undergone non-treelike or reticulate evolution. Such networks are essentially directed acyclic graphs with a leaf set that corresponds to a collection of species, and in which non-leaf vertices with indegree 1 correspond...

Interactions are essential to life. At the cellular level, the most fundamental processes rely on interactions between DNA, RNA, and proteins. Given that the structure and function of these molecules are determined by their sequence, it is ultimately the sequence that dictates the strength and specificity of these interactions. Thus, to improve...

Hydraulic transport pipelines are used in dredging, (wet) mining and deep sea mining. These pump-pipeline systems are typically designed using steady-state principles. However, recent cases have shown that steady-state design does not always guarantee stable pipelines. Transients like self-amplifying density waves have shown to be able to...

Shell structures can be either calculated with complex mathematics and differential geometry, or with the help of finite element method (FEM) software. Neither method gives the designer sufficient insight about the behaviour of the shell in the early design stage. The first method is for most designers too complex, it requires proficiency in at...

The energy transition towards decarbonization and modernization of the electric network requires the development of new technologies. Offshore windfarms, essential to this transition, rely on Gas-Insulated Systems (GIS) due to their compactness and extended lifespan. Despite the reliability of GIS, the high maintenance costs and severe...

Cardiovascular diseases stand as the leading cause of death worldwide. Cardiovascular diseases are a group of disorders of the heart and blood vessels, such as atherosclerosis, congenital heart diseases, rheumatic heart diseases, and arrhythmias. Early detection of cardiovascular issues is imperative for effective treatment, and the...

In this thesis, research is presented that explores the characteristics and possibilities of hole spin qubits defined in quantum dots in a germanium/silicon germanium heterostructure. The results of the most important experiments are concerned with distributing quantum information: either by entangling three qubits as the basis for the phase...

Improving the efficiency in deploying deep neural networks (DNNs) and processing complex high-dimensional data has drawn increasing attention in recent years. Yet, the deployment of large DNN models is challenged by the high computational complexity and energy consumption, making it difficult to run on resource-constrained devices such as mobile...

In this thesis, we use mathematical models to assist the Dutch Ministry of Defence with understanding and decision-making within contemporary conflicts and crises. We explore ways to reduce the spread of COVID-19, study dynamics in the Sino-Indian border dispute, and investigate the value of scouting in conflicts involving autonomous systems. ...

Recently, there has been a growing need for sustainable agriculture to increase food security, alleviate poverty, and contribute to climate change mitigation. Smallholder farmers (SFs) play a key role in this endeavor as they are a considerable segment of the global farming population. Despite their relevance, SFs face several challenges that...

Correlative light-electron microscopy (CLEM) combines the molecular specificity of fluorescence microscopy (FM) with the ultrastructural resolution of electron microscopy (EM) to provide functional information in the context of structural detail. However, the correlation between the two modalities is hindered by a 100-fold resolution gap....

Over many decades, intensive studies have been performed towards safe and sustainable substitutes for chromate corrosion inhibitors in active corrosion protection coatings for aerospace aluminium alloys. The proposed candidates must provide similar corrosion protection as compared to that of chromate-based compounds and be cost-effective for...

Genetic information encoded in the DNA sequences is maintained, replicated, and transcribed across the tree of life. Organisms evolved multiple hierarchical layers of chromosome organization which ensure that DNA can be contained but also processed within individual cells. This thesis focuses on SMC (Structural Maintenance of Chromosomes)...

The main objectives of bioprocesses are to reliably deliver drugs in a relatively short time frame with high quality within a tight regulatory framework. Bioprocesses are highly complex, the level of automation is moderate, and there is constant pressure to improve efficiency and costs. In addition, climate change and resource scarcity...

This thesis explores the ethical challenges that a potential research program for solar climate engineering via Stratospheric Aerosol Injection (SAI) could incur. These ethical challenges are comprised of epistemic hurdles in relation to the research process, as well as societal questions of justice and the value of nature. The thesis proposes a...

Software testing is important to make sure that code works as intended. Traditionally, this verification process has relied on manual testing, which is not only time-consuming but also susceptible to human errors. Through the use of automated test case generation techniques, we can automate this process and reduce the time and effort needed to...

Induced seismicity refers to seismic events (earthquakes) triggered by human activities. Such events, even when characterized by relatively modest magnitudes, have the potential to jeopardize the safety of individuals, the surrounding environment, and infrastructure. <br/><br/>Production from hydrocarbon reservoirs can alter the in-situ stress...
