Kooij, C. (author)
Unmanned and low-manned transport has increasingly been studied this past decade. While there have been successful trials for autonomous navigation, unmanned cargo ships are not commercially available yet. First, this dissertation investigates how changes to a ship’s systems and organizational structure can affect the crew’s size and composition...

This dissertation focuses on the Eems-Dollard estuary in the north of the Netherlands and contributes to the MVED (’Meerjarige Veldmetingen Eems-Dollard’) field measurement project in the area. The Eems-Dollard estuary is part of the Wadden Sea, a shallow shelf sea with barrier islands, deep tidal channels, shallow tidal flats and wetlands. The...

Erdmanis, J. (author)
The microscopic theory of superconductivity proposed by John Bardeen, Leon Cooper, and John Robert Schrieffer has been a vital milestone of condensed matter physics and the basis of development of new quantum technologies. It explained the superconductivity as an emergent phenomenon arising from weak phonon-mediated attraction of individual...

Data transmission is ubiquitous in all walks of life, ranging from basic home and office appliances like compact disc players and hard disk drives to deep space communication. More often than not, the communication and storage channels are noisy, and data might be distorted during transmission. However, noise is not the only disturbance during...

Campos Martins, G. (author)
This thesis presents the design and measurement of an RF energy harvesting and power management unit that operates across a wide range of available input power. The system comprises an adaptive impedance matching network, a single-stage cross-coupled differential-drive rectifier, a start-up charge pump, an adaptive buck-boost converter, a...

This thesis a method is described to include manufacturing constraints of the additive manufacturing process into topology optimization. Topology optimization often results in complex structures, which can only be produced by additive manufacturing. Although additive manufacturing has much fewer design restrictions compared to conventional...

Onstein, A.T.C. (author)
This thesis studies the factors that influence physical distribution structure design. Distribution Structure Design (DSD) concerns the spatial layout of the distribution channel as well as the location(s) of logistics facilities. Despite the frequent treatment of DSD in supply chain handbooks, an empirically validated conceptual framework of...

Phylogenetic networks are a type of graph with vertices and edges, used to elucidate the evolutionary history of species. The fundamental goal of phylogenetic research is to infer the true phylogeny of species from raw data such as DNA sequences and morphological data. Most network inference methods require one to solve an NP-hard problem;...

Studies of drought have increased in light of new data availability and advances in spatio-temporal analysis. However, the following gaps still need to be filled: 1) methods to characterise drought that explicitly consider its spatio-temporal features, such as spatial extent (area) and pathway; 2) methods to monitor and predict drought that...

Jafino, B.A. (author)
Climate change and anthropogenic pressures are threatening the livelihood of people in the world’s deltas. To secure a sustainable future, alternative courses of actions should be well prepared in advance, and their efficacy should be evaluated against future uncertainties. The assessment of alternative adaptation plans often takes an aggregate...

With continuous breakthroughs in quantum science and technology in recent years, the development of quantum computers is moving from pure scientific research to engineering realization. Meanwhile, the underlying physical structures also develop from the initial single qubit to multiple qubits or medium-scale qubit registers. Since qubits are...

Quantum computers can provide exponential speedup in solving certain computational problems pertaining to drug discovery, cybersecurity, weather forecasting, etc. Although a quantum computer with just 50-qubits has been shown to surpass the computing power of the best supercomputers in specific applications, millions of qubits would be required...

Ngo, Q.H. (author)
Flooding is one of the most frequently occurring and damaging natural disasters worldwide. Quantitative flood risk management (FRM) in the modern context demands statistically robust approaches (e.g. probabilistic) due to the need to deal with complex uncertainties. However, probabilistic estimates often involve ensemble 2D hydraulic model runs...

Coopmans, T.J. (author)
Communication between remote quantum computers enables tasks that are unachievable with their conventional counterparts, such as unconditionally-secure communication or quantum computing in the cloud. Bridging long distances, where the communication fundamentally suffers from loss, can be achieved by splitting up the distance into segments and...

Liu, H. (author)
The focus of this thesis is on the utilization of biodegradable drug nanocarriers combined with ionizing radiation in cancer treatment. Polymeric micelles based on PCL-PEO block copolymers were selected as the main platform for delivering various therapeutic substances due to their size, degradability and easy preparation. This thesis can...

Zhang, X. (author)
As a primary component of the marine propulsion systems, ship propellers have been traditionally made of nickel-aluminium-bronze (NAB) or manganese bronze (MB). With the development of fibre reinforced composite materials, the advanced plastic materials are considered to be applied in the manufacturing of marine propellers. Compared to...

In the current linear take-make-waste pattern the production of goods starts with raw material extraction followed by industrial conversion into products that are used and finally wasted. This linear system accelerates resource depletion and therefore hinders the development of sustainable societies. This is also valid for the use of water and...

Deaf people, who mainly use a signed language for communication, encounter multiple information accessibility challenges in their daily lives. Vital information, like health, has been limitedly accessible to Deaf people across the globe, including those in the Western Cape, South Africa—the studied context of this thesis. The lack of access to...

Offshore wind is expected to be one of the important contributors to the energy transition towards a more renewable and sustainable energy future. This can be clearly seen from the amount of investments over the past years as well as from the substantial upcoming offshore wind projects in the years to come. Many technological implementation...

Human-induced climate change is one of the challenges of our time. The increasing global mean temperature, shifts in precipitation patterns, and the rising sea level threaten ecosystems and natural resources, and pose a great risk on society at large. Policymakers need information about the expected impacts, as accurate as possible, in order to...
