Wiers, Christiaan (author)With the current transition towards renewable and high-tech solutions, the world is becoming increasingly complex. Consequently, the challenges faced by firefighters also intensify. For that reason, firefighting robots are rising in popularity despite being far from perfect. An important area of improvement is the perception capabilities of...master thesis 2024

Cools, Liam (author)Counter-acting image quality degradation caused by phase aberrations through physical correction requires the phase field to be known. As imaging hardware captures real-valued intensity, defined as the wave amplitude squared, obtaining this lost phase information is known as the phase retrieval problem and is a non-linear and non-convex...master thesis 2023

Verseput, Marien (author)Magnetic resonance imaging (MRI) is a non-invasive tool to image the body’s anatomy and physiology, but suffers from long scan times. Compressed Sensing (CS) is used to accelerate MRI scans by incoherently taking fewer measurements and using a nonlinear optimization algorithm to image the undersampled data. Convex optimization techniques are...master thesis 2023

Sitaram, Arnish (author)Unsteady numerical simulation has been proven to be an essential tool for research. The quality of the results can be improved by using mesh adaptation. Mesh adaptation uses error indicators to refine the mesh in regions with high errors. The error indicators used are output errors with the most accurate output error estimation method being...master thesis 2023

Talsma, Maaike (author)Osteoarthritis (OA) is a progressive joint degeneration disease resulting in joint pain, stiffness, and loss of mobility. Among patients with anterior cruciate ligament reconstruction (ACLR), OA incidence is increased. Articular cartilage (AC) degeneration is irreversible, therefore prevention and early detection are essential. Specifically, the...master thesis 2023

Berning, Max (author)Flood defense will have to be strengthened all over the world as sea level rise poses great challenges for the safety of coastal settlements. Strengthening traditional hard flood defenses is becoming increasingly more difficult due to limited space in the coastal zone and large costs inflicted with renovation. Adaptive ‘soft solutions’ pose an...master thesis 2023

El Coudi El Amrani, Nafie (author)Neural Radiance Fields (NeRFs) have demonstrated remarkable capabilities in photo-realistic 3D reconstruction. NeRFs often take as input posed images where the camera poses come from either off-the-shelf S\textit{f}M or online optimization together with NeRFs. However, we find that both strategies yield suboptimal results in recovering camera...master thesis 2023

Moes, Iris (author)<b>Introduction: </b>Breast reconstruction after a mastectomy is crucial to improve a patient’s quality of life. The Deep Inferior Epigastric artery Perforator (DIEP) flap procedure is considered the golden standard for breast reconstruction. Three-dimensional (3D) visualization methods have shown promise in providing a better understanding of...master thesis 2023

Ivanova, Daria (author)“Difficult heritage” often becomes a crucial point of current political and public debate in countries with totalitarian past (Vyazemtseva, 2020). This term refers mainly to architectural and sculptural monuments that were erected during the rule of totalitarian regimes, and it was first used relatively recently, in 2008 (Macdonald, 2008). At...master thesis 2023

Goedert, Gina (author)Once, counting as an important banking hub and capital for fashion design within the Arabian countries, Beirut’s favourable economic positioning was weakened by social unrests, political standstill, and economic volatility. Beirut’s population has been facing severe socioeconomic challenges for the past decades, also reflected in the fashion...master thesis 2023

Bekkers, Amerens (author)Introduction: Coronary atherosclerosis can form large lipid-rich plaques inside the arteries, which are prone to rupture. Rupture can lead to thrombus formation and subsequent obstruction of the blood flow, which is the most common cause of acute coronary events like myocardial infarction. Current imaging modalities lack the ability to image...master thesis 2022

de Boer, Dirk (author)In many flow experiments it is complex to measure all flow states of interest, leading to the need for a method to retrieve unmeasured flow states from measured ones. This work focuses on Hidden Fluid Mechanics (HFM), which refers to a Physics-Informed Neural Network (PINN) able to incorporate the Navier-Stokes (NS) equations into the loss...master thesis 2022

Wegener, Malte (author)Reconstructed Discontinuous Galerkin (rDG) methods aim to provide a unified framework between Discontinuous Galerkin (DG) and finite volume (FV) methods. This unification leads to a new family of spatial discretization schemes from order three upwards. The first of these new schemes is the rDG(P1P2) method, which represents the solution on each...master thesis 2022

Wang, Chuhan (author)3D scene reconstruction is a common computer vision task with many applications. The synthesized virtual environments are beneficial for many downstream applications such as 3D modeling, building inspection, virtual reality, etc. As conventional scene reconstruction methods often require expensive data collections and prior information on the...master thesis 2022

Meines, Wijnand (author)Bifacial modules are expected to have a 60% share in the PV market, which require spectral irradiance data incident on both sides to optimize the design. Sensors that provide spectrally resolved data are expensive and thus a cost-effective spectrally resolved albedometer was designed in two previous PVMD Master Theses. This albedometer measures...master thesis 2022

CHEN, ENPU (author)In inspection and display scenarios, reconstructing and rendering the entire surface of a building is a critical step in presenting the overall condition of the building. In building reconstruction, most works are based on point clouds because of their enhanced availability. In recent years, neural radiance fields (NeRF) have become a common...master thesis 2022

Hirsch, Quentin (author)In 3D seismic data acquisition, sufficiently dense spatial sampling is most often not possible, because of physical, financial, and temporal constraints. The resulting aliased data is a major obstacle for accurate subsurface images. Therefore, methods are needed to reconstruct these sparse data to an adequate sampling. We develop a novel...master thesis 2022

Minigher, Paolo (author)The reconstruction of the elastic deformed shape of a structure from strain measurements is a field which has received considerable attention over the years. This work aims to suggest some improvements for wing-like structures trying to limit as much as possible the amount of strain measurements needed. In particular, a simple beam model is...master thesis 2022

Xu, Jin (author)Federated learning is a private-by-design distributed learning paradigm where clients train local models on their own data before a central server aggregates their local updates to compute a global model. Depending on the aggregation method used, the local updates are either the gradients or the weights of local learning models. Unfortunately,...master thesis 2022
