Maximum Power Point Tracking (MPPT) is commonly used to optimize the power output of solar arrays for LEO satellites. Traditional MPPT techniques such as Perturb & Observe often struggle when the satellite is rotating and the temperature and incident irradiance are rapidly changing. This scenario frequently occurs with miniaturized...

From the perspective of wheelchair sports practice, there is a growing need to provide feedback on power output. Power can be used to monitor athletes' fitness and fatigue levels, thereby preventing overtraining and potential injuries, to individualize and analyze training programs, and it is also an objective measure of effort or intensity....

We have a general idea of what the term empathy refers to. We typically use the concept in a normative way - to express appreciation, concern, value, risks, etc, - with regard to how we relate to one another. However, the exact meaning of the concept is far from agreed upon. As such, it actually is unclear whether and how we can fairly use this...

This dissertation centers around two topics: graphene nanoribbons (GNRs) and superconductors. The aim of this thesis is to work towards combine these two topics, in order to study how superconducting correlations interact with magnetic correlations within graphene nanoribbons, such as the magnetic edge states present in the zigzag edges of...

Recently, quantum networks have emerged as a focal point of research and discussion due to their promise in overcoming the limitations of classical networks, offering unparalleled capabilities in secure communication, quantum computation, and distributed quantum information processing. Simply speaking, a quantum network is a network in which the...

Predicting aircraft Take-Off Weight (TOW) has been a long-sought task by aviation stakeholders, especially for operational and regulatory bodies involved in flight planning. Unfortunately, TOW being a sensitive parameter to operational trends and cost indices, aircraft operators tend to keep it confidential. In recent years, Machine Learning (ML...

Building materials generally perform poorly in a high temperature environment. Residential fires and fires in road tunnels are common occurrences. Furthermore, some factories have no option besides exposing their infrastructure to very high temperatures due to the nature of their operation logistics. Therefore, there is a clear need for...

Introduction: Movement disorders, such as Cerebral Palsy, prevent children from fully developing their motor coordination abilities reducing their quality of life. Trunk control is a core coordination competency but there is limited variety in sitting based therapies. This paper investigates a theorised trunk support device for children which...

Communications networks such as opportunistic mobile networks, vehicle networks, and social contact networks can be represented as temporal networks, where two cars or individuals are connected at a discrete time step if they are close to each other or interact with each other at that time step. These networks facilitate the propagation of...

With climate change posing an increasing danger to society, the Advisory Council for Aviation Research and Innovation in Europe (ACARE) has set a target to reduce $CO_2$ emissions by 75\% and $NO_x$ emissions by 90\% per passenger kilometre from the aviation sector by 2050 with respect to a baseline aircraft in service in the year 2000 [3]. The...

Race cars use aerodynamic downforce to reduce the lap times by increasing grip. Diffusers, upswept ramps located at the rear of a vehicle, are often used to enhance downforce. This investigation proposes a novel LPT facility featuring HFSB, LED illumination, and high-speed cameras to characterize the flow inside automotive diffusers. An RC car,...

Exploring planetary bodies using robot swarms can potentially increase the value of the exploration missions; enabling the execution of novel measurements and explorations previously deemed impractical or unattainable. Despite its potential, the technology readiness level of planetary swarms is not very mature. This work uses multi-agent...

This thesis investigates the use of artificial intelligence (AI) in public policy execution. To contribute to preserving citizen autonomy, it introduces the concept of ‘contestability’—a system quality that ensures citizens retain control over their lives in the face of AI systems and can influence AI system development. The central research aim...

There is a very popular fable, dating back to the early 1800s, about three little pigs that build their houses of different materials and a wolf that tries to catch them by blowing down their houses. From the three houses built from straws, sticks or bricks, only the house made out of bricks withstands the blow of the wolf. Although the moral of...

Inspired by the leading-edge protuberances found on the flippers of humpback whales, tubercles have drawn significant interest for improving airfoil aerodynamic performance. In static conditions, airfoils with tubercles exhibit a softer onset of stall and increased lift in post-stall regime, though with a reduced maximum lift coefficient....

The wrist is one of the most complex joints in the human body, comprised of multiple bones and ligaments, and capable of performing a variety of movements. Proper wrist motion relies heavily on the interplay between the carpal bones of the hand and its ligamentous connections, and when that interplay is compromised hand function can be severely...
