At speeds roughly between five and ten thousand km/h, hypersonic aircraft offer the promise of an extremely fast means of transport. Growing concerns about climate warming, however, direct attention to sustainability. This thesis focuses on atmospheric composition and radiation changes by considering a range of individual hypersonic aircraft...

Franse, W.J.M. (author)
The field of quantum acoustics studies high frequency sounds generated at low temperatures such that quantum mechanical effects become relevant. The studies mainly revolves around propagating quantized sound waves, or phonons, a collective excitation of atoms in solids or liquids. In quantum acoustics, the engineering and design tools described...

About 70 prestressed concrete T-beam bridges, constructed in the Netherlands between 1953–1977, are still in use today with many located in the main highway network. This type of bridge consists of prefabricated and prestressed T-shaped beams, with an integrated deck slab, cross-beams and transverse prestressing. Even if these bridges are well...

Food and medicines are two of the most essential categories of goods for human beings, providing vital nourishment and healthcare. However, as these products are commercialized and distributed on a global scale, consumers face the threat of counterfeit and deteriorated products. In response, this dissertation presents four prototypes consisting...

This study investigates the impact of smartphone use on passengers' comfort during travel, focusing on train trips. The literature review reveals that smartphones have become the primary activity for train passengers, leading to discomfort and potential musculoskeletal issues, particularly in the neck, shoulders, arms, and back. The study aims...

Humans have intervened in rivers for centuries. River engineering measures have aimed at protecting populations against flooding, ensuring reliable and safe navigation, providing freshwater for drinking, domestic and industrial use, irrigation, and energy supply, and providing opportunities for recreation. All around the world, measures such as...

Alkaliphiles thrive in environments with a pH of 8.5 or above, while maintaining an internal pH closer to neutral. Thus, alkaliphilic microorganisms have a proton gradient inverted with respect to the normal orientation. Intuitively, this would nullify the potential to generate energy via respiration with regularly oriented respiratory chains...

Vos, J. (author)
This dissertation explores what road characteristics trigger drivers’ speed adjustments when approaching freeway curves. It combines speed prediction modelling and human factors research methods. The results show that drivers primarily consider visible cues such as the preceding roadway, deflection angle, and the number of lanes, as opposed to...

Spitzbarth, B. (author)
Nature has inspired countless researchers in their quest to understand the phenomena we observe and utilise their findings to develop new technologies. This becomes especially apparent in systems chemistry, which heavily draws inspiration from natural systems in its pursuit for the understanding and development of chemical reaction networks ...

When considering air quality, notably in South America, it seems that we are falling behind more developed regions in exacerbating the issue. This shortfall serves not just as observation, but as a warning, as air quality problems here are rapidly escalating. Nevertheless, by examining how other countries have addressed similar issues, we can...

Souaid, C. (author)
This thesis examines the potential of small, low-carbon, (near) zero-energy dwellings as a solution that would both address sustainability challenges and answer to the growing housing shortage in North-West Europe. It adopts a multidimensional outlook that encompasses institutional, social and technical aspects surrounding the dwellings. The...

Vilkelis, K. (author)
A large part of condensed matter physics concerns itself with understanding the behaviour of electrons in solids and finding ways to control them. However, in mesoscopic systems (i.e., systems with nanometer to micrometre scale), the behaviour of electrons is difficult to predict through the Schrödinger equation. Instead, it is often more...

Distributed Acoustic Sensing (DAS) is a versatile dynamic strain sensing method that has been adopted for a wide range of seismic applications. In DAS, optical fibres are interrogated and used as sensors, where a strain or strain-rate measurement is made along a specific length of the fibre, called the gauge length. Its main appeal is the...

The biopharmaceutical industry is moving from a batch to a continuous mode of manufacturing. This shift promises to reduce costs and manufacturing footprint while improving productivity and consistency of the product. This thesis implements miniaturized and automated high-throughput screening techniques alongside a mathematical chromatography...

Physical human-robot cooperation (pHRC) has the potential to combine human and robot strengths in a team that can achieve more than a human and a robot working on the task separately. However, how much of the potential can be realized depends on the quality of cooperation, in which awarenes of the partner’s intention and preferences plays an...

Consider a random vector y = Σ <sup>1/2</sup> x, where the p elements of the vector x are i.i.d. real-valued random variables with zero mean and finite fourth moment, and Σ <sup>1/2</sup> is a deterministic p × p matrix such that the eigenvalues of the population correlation matrix R of y are uniformly bounded away from zero and infinity. In...

In recent years, Flash Delivery services have gained great popularity. Flash Delivery is a service where goods of daily need can be ordered on-demand and subsequently are delivered to the customer within a short time window, for example, in the next ten minutes. Operational efficiency and cost management are vital for sustainability in this...

Seismic survey design deals with determining the acquisition parameters that lead to the best possible imaging and characterization of the subsurface. The design of the survey is constrained by health, safety and environmental considerations and the available budget, seeking for a balance between quality and cost. Because seismic exploration is...

The ongoing growth of the global population has led to increased resource consumption, particularly in the realm of water resources, resulting in potential shortages and environmental concerns. The surge in industrialization has intensified the demand for freshwater, consequently causing significant contamination of global water sources through...

Varbanov, B.M. (author)
The theory of quantum mechanics describes many phenomena that may initially seem to be counter-intuitive and, in some cases, impossible, given the understanding of classical mechanics that most of us are more intimately familiar with. Following its initial introduction, there was a great deal of debate among scientists regarding the predictions...
