Roosen, M.A. (author)
In the design process of prestressed bridges and viaducts, the required amount of shear reinforcement is determined with a model that assumes the presence of flexural cracks. In order to keep the design process simple, this model is also prescribed to determine the amount of shear reinforcement for the regions of the structure in which, at the...

Humans are incapable of attending to everything at the same time. The serial nature of focused attention limits the information intake capacity of the perceptual system. This thesis deals with the measurement and modelling of visual attention distribution. It is examined whether measures of visual attention are predictive of task performance....

The continuous increase in the number of flights in the last decades caused a steepgrowth of aviation-related pollution to the point that the aviation sector is responsible for3% of the global greenhouse gas emissions. Regulators have been slow at catching up withthis problem, and stringent emission targets have been put in place only very...

The COVID-19 pandemic had a significant impact on the aviation industry with more than 60% reduction in the passenger traffic in the year 2020 compared to year 2019. The passenger traffic which is now expected to reach the 2019 level only around the year 2024 will still continue to grow but at a lower pace compared to the pre pandemic levels....

The Atlantic Meridional Overturning Circulation (AMOC) quantifies the strength of the northward surface transports and southward deeper transports in the Atlantic Ocean. In particular, as warm surface waters flow northward in the Atlantic they gradually cool on they journey releasing heat to the atmosphere. Then, in the subpolar and polar...

Batteries gained a lot of attention due to a raising demand for energy storage, as required for renewable energy generation systems, portable electronics and transport applications. For the development of new battery materials understanding of fundamental processes is essential, which often relies on the development of new characterisation...

Specialized tools, such as IDEs, issue trackers, and code review tools, are an indispensable part of the modern software engineering process. These tools are constantly evolving. Besides enabling tools to support a wider range of technologies and frameworks, we are learning to provide additional features in completely new ways. One prominent...

Driven by a quest for efficiency, many Western countries have witnessed merger waves across the entire breadth of their public sectors. The underlying assumption is that economies of scale exist in public service delivery; the idea that the average cost of public services decreases as the size of public organizations increases. The analysis of...

Traffic congestion on motorways has become a common phenomenon across the world. Congestion on motorways is a major discomfort to road users and causes many problems such as reducing the capacity of the motorways, increasing travel times and fuel consumption leading to high economic and societal costs. Alleviating congestion and providing better...

Automated testing has become an essential process for improving the quality of software systems. Automated tests can help ensure that production code is robust under many usage conditions and that code meets performance and security needs. Nevertheless, writing effective tests is challenging and, unfortunately, often neglected. In the first part...

Frugal innovation emphasizes the reduced use of resources and cutting of costs through the process of innovating around constraints. However, how innovating around constraints leads to profitable (value creation) businesses and local economic development impact (value capture) is still unclear. Early frugal innovation literature assumed that a...

Road safety is still a challenging issue. In 2020, 1.35 million people have died as a result of traffic accidents, where the number one cause of death for young adults between the age of 5 and 29 is car accidents. In an attempt to improve road safety, the automotive industry has developed numerous types of Advanced Driver Assistance Systems ...

Faced with the highly overlapping factors of the external disturbances -- natural disasters caused by extreme climate change, and internal interactions -- the contradiction between natural conditions and rapid urbanization, traditional spatial planning and design used to pursue economic development could not be flexible enough to respond to the...

We propose a microscopy scheme for the controlled modulation of the electron wave front that utilizes patterned electron mirrors. The ability to control the wave front of the electron finds many applications in electron microscopy, for instance in contrast enhancement techniques, beam mode conversion, low-dose imaging techniques such as quantum...

Alkali-activated materials (AAMs), as eco-friendly alternatives to Ordinary Portland cement (OPC), have attracted increasing attention of researchers in the past decades. Unlike cement, which requires calcination of limestone, AAMs can be made from industrial by-products, or even wastes, with the use of alkali-activator. The production of AAMs...

Expanding cities across the world rely increasingly on the global food network, but should they? Population growth, urbanisation and climate change place pressure on this network, bringing its resilience into question. For decades urban agriculture has been discussed in popular media and academia as a potential solution to improve food security,...

van der Helm, M.P. (author)
The entire research described in this thesis is part of the larger field of Systems Chemistry. This field of chemistry deals with the understanding of the complexity of biology by mimicking biochemical reaction networks with emergent properties attributed to the entire system. In particular, this research focuses on the design of artificial non...
