All ecosystem services of river are governed by flow regime. The different components of flow regime like topography, geology, and climatic variation contribute to different ecological processes. These ecosystems provide a wide range of direct and indirect benefits to a human being. The ecosystem services such as hydropower, irrigation, drinking...

On board of High Speed marine Craft (HSC), the crew and the passengers are exposed to high levels of Whole Body Vibrations (WBV) and large magnitude Repeated mechanical Shocks (RS) caused by the motions of the craft. The HSCs are typically 10 meters long, capable of reaching a maximum speed up to 50 knots and widely used by various maritime...

EPA: Multi-Modelling for Complex Challenges With the acknowledgement of international grand challenges, the demand for better and ever more complex models is likely to increase a manifold. Where single models may no longer be able to grasp the complexities of a system, multi-modelling (Nikolic, Warnier, et al., 2019;...

The constant pressure on the maritime sector to reduce Greenhouse Gas (GHG) emissions has led the shipping industry to search for alternatives, such as zero-emissions propulsion systems, which would allow meeting the 2050 target imposed by International Maritime Organization (IMO) regulation. Fuel cells have demonstrated to substantially...

Socio-technical systems consist of deeply interconnected and interdependent social entities and technical systems that collaborate to achieve a global goal. The individual characteristics and behaviours of each involved actor and their interactions define the resulting overall emergent system behaviour. Due to increased complexities in socio...

Migrants are moving in great numbers towards urban areas as a result of urbanization and drivers such as political-, economical- and climate crises. The influx of new people brings new challenges for cities and municipalities to provide for a suitable environment for new and existing citizens whilst preventing adverse effects to occur. Current...

Multi-robot motion planning without a central coordinator usually relies on the sharing of planned trajectories among the robots via wireless communication in order to achieve predictive collision avoidance. Path planners found in the literature that feature this scheme usually boast levels of performance comparable with their centralized...

After en bloc resection of primary pelvic bone tumours, orthopaedic oncologists usually try to perform reconstruction in order to achieve limb salvage. Reconstruction after these types of resections is challenging. Especially when the total ilium and parts of the sacrum needs to be removed. One of the reconstructive options is endoprosthetic...

Graph Neural Networks are a unique type of Deep Learning models that have a capability to exploit an explicitly stated structure of data representation. By design they carry a strong relational inductive bias, which is a set of assumptions that makes the algorithm prioritize some solutions over another, independent of observed data. This makes...

The field of prognostics on composites is relatively young, and research is focused on constant amplitude fatigue (CAF) loading, whereas variable amplitude fatigue (VAF) loading is more common in actual use-cases. Therefore in this research, the feasibility of different in-situ, data-driven probabilistic models is studied for prognostics on...

The urgent transition to other forms of energy production, delivery and consumption has induced investments in new technologies such as renewable energy sources, storage units and demand response programs. Investments in these assets represent long-term commitments (e.g. 40 years ahead) from civil society, governmental institutions and capital...

This research attempts to investigate the coastal flow structure horizontally. The flow cases with different flow directions, including perpendicular and parallel to the shoreline directions, are selected by analyzing the New Europe Wind Atlas (NEWA) reanalysis data. After the cases are determined, high-resolution Weather Research and...

This thesis presents the design of a performance prediction simulation model for an ship-to-shore crane. Current STS crane models do not take new trends in container terminal operations into account like automation. These models do not predict the performance accurately. This can lead to logistical and financial <br/>consequences. Automation...

Due to their simple structure and the possibility for in situ doping, light emitting electrochemical cells (LECs) are shaping up to be a cheap and easily produced alternative to LEDs. To date, little research has been done to combine the luminescent properties of colloidal quantum dots (QDs) with the LEC concept. In this thesis, steps are taken...

Climate change is a large and global concern. The healthcare sector contributes between 6% and 10% to national carbon emissions in developed countries. Within the healthcare sector, operation rooms are very resource-intensive. A lot of energy, medical products, equipment and pharmaceuticals are required to perform surgery on a daily basis. This...

During the past decade, the offshore wind energy industry evolved to bigger turbines, going into deeper waters and farther offshore. As bottom-fixed wind turbines are limited to shallow water depths, floating wind structures are the next frontier to unlock the vast potential of wind energy. Despite many techno-economic challenges, several full...

With increased awareness of anthropogenic emissions, industries and sectors worldwide are changing rapidly. One of those sectors is the transport sector which has seen immense change with the increase of electric vehicles in recent years. Although these electric vehicles reduce emissions and are a welcoming sign of change, they greatly increase...

Exposure to excessive community noise has become a large environmental health concern. Noise pollution continues to increase while it is accompanied by direct, as well as cumulative adverse health effects. In addition, prolonged exposure to excessive noise levels also has a negative economic impact. The incorporation of numerical tools in the...

The last decade has seen an immense growth in solar PV systems (both large-scale solar PV systems and distributed solar PV systems). It is expected that this growth will continue due to environmental concerns. Since conventional generators are defined by their physics and control, and solar PV systems are defined solely by their control...

The Oscillating Water Column (OWC) device is one of many available technologies for generating electricity from water waves. It is a caisson-like structure, which houses a water column in an enclosed chamber with an inlet at the bottom. Waves enter the device, exciting the water column. The trapped air above is forced out through a turbine,...
