Restrepo Sierra, A.M. (author)
Life, the most complex and admirable machine that one could think of has evolved over billions of years to display a beautiful variety of mechanisms that keep cells adapting, self-maintaining, reproducing, and evolving. If we think about it, what is this magic? What are the mechanisms behind life’s origins and wonderful coordination? Attracted...

How does the small intestine maintain itself? What mechanism does it use to achieve<br/>homeostasis, and how optimal is this mechanism? We approached these questions<br/>mainly using cell tracking in organoids, for which we developed new cell trackers.<br/>We found that the intestinal crypt uses a surprisingly simple and effective strategy.<br/...

In this thesis, we aim to improve the application of deep reinforcement learning in portfo- lio optimization. Reinforcement learning has in recent years been applied to a wide range of problems, from games to control systems in the physical world and also to finance. While reinforcement learning has shown success in simulated environments (e.g....

Aerodynamic stall has been a critical factor in recent aircraft crashes, leading to revisions in the regulations on the fidelity of stall models in flight simulation training devices. However, the updated regulations still lack a clearly defined accuracy required for effective pilot training. To determine the required accuracy, this research...

Plastics have become indispensable in modern life due to their versatility and affordability. However, their widespread use has resulted in far-reaching environmental damage, including the accumulation of plastic waste, fossil fuel depletion, and significant greenhouse gas emissions. Bio-based plastics have been proposed as a sustainable,...

The digital world is evolving toward representing - and serving the interconnection of - natural persons. Instead of depending on the intrastructure of Big Tech companies and governments, users can cooperate and use their hardware to form public infrastructure. Instead of existing by virtue of a reference in some institution's database, users...

The transport sector in the Netherlands is under pressure to reduce emissions, constituting about 12% of the country's total emissions, to align with the goals of the Paris Agreements. One promising solution is the adoption of hydrogen fuel cell heavy-duty trucks, particularly for long-haul transport, providing emission-free operation when...

Brachytherapy (BT) is an essential component in the curative treatment of cervical cancer. With commercial BT implant devices, called applicators, the radioactive sources can only be positioned in fixed intracavitary channels or in a fixed array of interstitial needles. Patient-tailored BT applicators containing individualised needle channels...

As an alternative to kerosene (Jet-A1), green hydrogen is considered a potential solution to reduce the environmental impact of the medium-range aviation industry. While the technical feasibility of liquid hydrogen (LH2)-powered aircraft is already being researched and demonstrated, the required infrastructure, as well as its impact on the...

The origin of the Martian dichotomy is subject to question and no substantial evidence exists. Some surface and interior features that are not visible in, e.g., topography data, can show up in gravity data. Therefore, this research inverts gravity data to find a crustal and mantle global density model. Previous research performed a one-layer...

The tissue electrical properties of conductivity and permittivity affect the interactions of electromagnetic fields in the body. These properties vary throughout the different tissues as the tissue structure and composition varies. In this thesis, medical imaging and diagnosis is used as primary example to motivate exploration of a novel...

Brackish waters can be found in transition zones between freshwater rivers and saltier seas. These dynamic coastal landscapes harbor multiple functions such as housing, agriculture, nature, and industry. Because of climate change, existing borders between fresh and saline water - and between land and water - are becoming contested. Extreme...

The electricity grid in the Netherlands is highly congested and poses a significant challenge due to increasing demand and the transition to sustainable energy sources, which overwhelms the existing infrastructure. To address this issue, Distribution System Operators (DSOs) like Alliander are tasked with managing waiting lists for power...

The increasing dependence on technology has made society vulnerable to cyber threats, with ransomware becoming a major concern. The complex nature of the Ransomware-as-a-Service (RaaS) model makes identifying the attackers challenging. Traditional methods often rely on direct indicators, but these may not be readily available or reliable. This...

Wind energy is one of the most important renewable energy sources, effectively addressing climate change issues and promoting sustainable development on a global scale. Blade failures may cause long shut-down times and may present a safety hazard. Continuous and real-time monitoring of the blade conditions is helpful for finding blade damage at...

Since the introduction of cementitious materials, shrinkage-induced earlyage cracking (EAC) has emerged as a significant issue that negatively influences the function, durability, and aesthetics of concrete structures like dams, tunnels, and underground garages. This thesis aims to develop new experimental and modelling techniques that help...

While learning-based control techniques often outperform classical controller designs, safety requirements limit the acceptance of such methods in many applications. Recent developments address this issue through Certified Learning (CL), which combines a learning-based controller with formal methods to provide safety guarantees. This thesis...

Privacy-enhancing technologies (PETs) have historically been used for safeguarding individual privacy from both public and private interference. But lately, tech companies have started using PETs as one instrument for the expansion of their power over different actors, as appears to be unfolding in the case of Amazon’s Sidewalk service: a United...
